-
-	* st.c: uses malloc instead of xmalloc to avoid GC. syck uses st_insert
-	  in gram.c to insert node from rb_syck_bad_anchor_handler into
-	  SyckParser's hash table. if GC occurs in st_insert, it's not under
-	  SyckParser's mark system yet. so RString can be released wrongly.
-
-	* ext/syck/syck.h (S_FREE): small hack. no need to check if pointer is
-	  NULL or not before S_FREE.
-
-	* ext/syck/rubyext.c (syck_parser_assign_io): rb_check_string_type can
-	  return new RString. if so, it becomes unreachable from GC after

-	  so no need to check if NULL, and "volatile VALUE hash"

-	  not syck_free_node, and it won't free data.str->ptr and type_id.

-	  pipe. So socket handle didn't reach winsock's select function.
-
-	* win32/win32.c (rb_w32_select): read for pipe was still blocked

-
-	    r,w = IO.pipe

-
-	* lib/{soap,wsdl,xsd}, test/{soap,wsdl,xsd}: imported soap4r/1.5.4.
-
-	  == SOAP client and server ==
-
-	  === for both client side and server side ===
-
-	  * improved document/literal service support.
-	    style(rpc,document)/use(encoding, literal) combination are all
-	    supported.  for the detail about combination, see
-	    test/soap/test_style.rb.
-
-	  * let WSDLEncodedRegistry#soap2obj map SOAP/OM to Ruby according to
-	    WSDL as well as obj2soap.  closes #70.
-
-	  * let SOAP::Mapping::Object handle XML attribute for doc/lit service.
-	    you can set/get XML attribute via accessor methods which as a name
-	    'xmlattr_' prefixed (<foo name="bar"/> -> Foo#xmlattr_name).
-
-	  === client side ===
-
-	  * WSDLDriver capitalized name operation bug fixed.  from
-	    1.5.3-ruby1.8.2, operation which has capitalized name (such as
-	    KeywordSearchRequest in AWS) is defined as a method having
-	    uncapitalized name. (converted with GenSupport.safemethodname
-	    to handle operation name 'foo-bar').  it introduced serious
-	    incompatibility; in the past, it was defined as a capitalized.
-	    define capitalized method as well under that circumstance.
-
-	  * added new factory interface 'WSDLDriverFactory#create_rpc_driver'
-	    to create RPC::Driver, not WSDLDriver (RPC::Driver and WSDLDriver
-	    are merged).  'WSDLDriverFactory#create_driver' still creates
-	    WSDLDriver for compatibility but it warns that the method is
-	    deprecated.  please use create_rpc_driver instead of create_driver.
-
-	  * allow to use an URI object as an endpoint_url even with net/http,
-	    not http-access2.
-
-	  === server side ===
-
-	  * added mod_ruby support to SOAP::CGIStub.  rename a CGI script
-	    server.cgi to server.rb and let mod_ruby's RubyHandler handles the
-	    script.  CGIStub detects if it's running under mod_ruby environment
-	    or not.
-
-	  * added fcgi support to SOAP::CGIStub.  see the sample at
-	    sample/soap/calc/server.fcgi.  (almost same as server.cgi but has
-	    fcgi handler at the bottom.)
-
-	  * allow to return a SOAPFault object to respond customized SOAP fault.
-
-	  * added the interface 'generate_explicit_type' for server side
-	    (CGIStub, HTTPServer).  call 'self.generate_explicit_type = true'
-	    if you want to return simplified XML even if it's rpc/encoded
-	    service.
-
-	  == WSDL ==
-
-	  === WSDL definition ===
-
-	  * improved XML Schema support such as extension, restriction,
-	    simpleType, complexType + simpleContent, ref, length, import,
-	    include.
-
-	  * reduced "unknown element/attribute" warnings (warn only 1 time for
-	    each QName).
-
-	  * importing XSD file at schemaLocation with xsd:import.
-
-	  === code generation from WSDL ===
-
-	  * generator crashed when there's '-' in defined element/attribute
-	    name.
-
-	  * added ApacheMap WSDL definition.
-
-	* sample/{soap,wsdl}: removed.

-
-	* lib/csv.rb: [CAUTION] API change
-

-	    CSV::Row was a subclass of Array, it won't hurt almost all programs
-	    except one which depended CSV::Row#match.
-
-	  * CSV::Cell removed.  a cell is represented as just a String or

-
-	* lib/csv.rb: [CAUTION] record separator(CR, LF, CR+LF) behavior
-	  change.  CSV.open, CSV.parse, and CSV,generate now do not force
-	  opened file binmode.  formerly it set binmode explicitly.
-
-	  with CSV.open, binmode of opened file depends the given mode
-	  parameter "r", "w", "rb", and "wb".  CSV.parse and CSV.generate open
-	  file with "r" and "w".
-
-	  setting mode properly is user's responsibility now.
-
-	* lib/csv.rb: accepts String as a fs (field separator/column separator)
-	  and rs (record separator/row separator)
-

-
-	* ext/tk/lib/tkafter.rb: support 'wait on a thread' and 'wait on

-
-Thu Oct  9 12:05:46 2003  Eric Sunshine <sunshine@sunshineco.com>
-
-	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
-	  had become unbuildable; enhanced --enable-fat-binary option so that
-	  it accepts a list of desired architectures (rather than assuming a
-	  fixed list), or defaults to a platform-appropriate list if user does
-	  not provide an explicit list; made the default list of architectures
-	  for MAB (fat binary) more comprehensive; now uses -fno-common even
-	  when building the interpreter (in addition to using it for
-	  extensions), thus allowing the interpreter to be embedded into a
-	  plugin module of an external project (in addition to allowing
-	  embedding directly into an application); added checks for
-	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
-	  ensures that -I/usr/local/include is employed when extensions'
-	  extconf.rb scripts invoke have_header() since extension checks on
-	  NextStep and OpenStep will fail without it if the desired resource
-	  resides in the /usr/local tree; fixed formatting of --help message.
-
-	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
-	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
-	  (see configure's --enable-fat-binary option); added rule for new
-	  missing/getcwd.c.
-
-	* defines.h: fixed endian handling during MAB build (see configure's
-	  --enable-fat-binary option) to ensure that all portions of the
-	  project see the correct WORDS_BIGENDIAN value (some extension modules
-	  were getting the wrong endian setting); added missing constants
-	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
-	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
-	  define in NeXT section.
-
-	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
-	  NextStep since, on some installations, this value always resolves
-	  uselessly to zero.
-
-	* dln.c: added error reporting to NextStep extension loader since the
-	  previous behavior of failing silently was not useful; now ensures
-	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
-	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
-	  on Rhapsody since this header lacks multiple-include protection,
-	  which resulted in "redefinition" compilation errors.
-
-	* main.c: also create hard reference to objc_msgSend() on NeXT
-	  platforms (in addition to Apple platforms).
-
-	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
-	  makefiles so that extensions can be built MAB (see configure's
-	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
-	  (but not cpp_command() because MAB flags are incompatible with
-	  direct invocation of `cpp').
-
-	* ext/curses/extconf.rb: now additionally checks for presence of these
-	  curses functions which are not present on NextStep or Openstep:
-	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
-	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
-	  wscrl(), wsetscrreg()
-
-	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
-	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
-	  window_bkgd() to correctly return boolean result rather than numeric
-	  result; fixed window_getbkgd() to correctly signal an error by
-	  returning nil rather than -1.
-
-	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
-	  pointers before invoking rb_tainted_str_new2() upon fields extracted
-	  from `struct passwd' and `struct group' since null pointers in some
-	  fields are common on NextStep/OpenStep (especially so for the
-	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
-	  when it receives a null pointer.
-
-	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().
-
-	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
-	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
-	  (char*) for older platforms such as NextStep and OpenStep.
-
-	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup(); include
-	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
-	  argument of gethostbyaddr() and getservbyname() from (const char*) to
-	  non-const (char*) for older platforms.
-
-	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+# NEWS for Ruby 3.2.0
+
+This document is a list of user-visible feature changes
+since the **3.1.0** release, except for bug fixes.
+
+Note that each entry is kept to a minimum, see links for details.
+
+## Language changes
+
+* Anonymous rest and keyword rest arguments can now be passed as
+  arguments, instead of just used in method parameters.
+  [[Feature #18351]]
+
+    ```ruby
+    def foo(*)
+      bar(*)
+    end
+    def baz(**)
+      quux(**)
+    end
+    ```
+
+* A proc that accepts a single positional argument and keywords will
+  no longer autosplat. [[Bug #18633]]
+
+    ```ruby
+    proc{|a, **k| a}.call([1, 2])
+    # Ruby 3.1 and before
+    # => 1
+    # Ruby 3.2 and after
+    # => [1, 2]
+    ```
+
+* Constant assignment evaluation order for constants set on explicit
+  objects has been made consistent with single attribute assignment
+  evaluation order. With this code:
+
+    ```ruby
+    foo::BAR = baz
+    ```
+
+    `foo` is now called before `baz`. Similarly, for multiple assignments
+    to constants,  left-to-right evaluation order is used. With this
+    code:
+
+    ```ruby
+    foo1::BAR1, foo2::BAR2 = baz1, baz2
+    ```
+
+    The following evaluation order is now used:
+
+    1. `foo1`
+    2. `foo2`
+    3. `baz1`
+    4. `baz2`
+
+    [[Bug #15928]]
+
+* "Find pattern" is no longer experimental.
+  [[Feature #18585]]
+
+* Methods taking a rest parameter (like `*args`) and wishing to delegate keyword
+  arguments through `foo(*args)` must now be marked with `ruby2_keywords`
+  (if not already the case). In other words, all methods wishing to delegate
+  keyword arguments through `*args` must now be marked with `ruby2_keywords`,
+  with no exception. This will make it easier to transition to other ways of
+  delegation once a library can require Ruby 3+. Previously, the `ruby2_keywords`
+  flag was kept if the receiving method took `*args`, but this was a bug and an
+  inconsistency. A good technique to find the potentially-missing `ruby2_keywords`
+  is to run the test suite, for where it fails find the last method which must
+  receive keyword arguments, use `puts nil, caller, nil` there, and check each
+  method/block on the call chain which must delegate keywords is correctly marked
+  as `ruby2_keywords`. [[Bug #18625]] [[Bug #16466]]
+
+    ```ruby
+    def target(**kw)
+    end
+
+    # Accidentally worked without ruby2_keywords in Ruby 2.7-3.1, ruby2_keywords
+    # needed in 3.2+. Just like (*args, **kwargs) or (...) would be needed on
+    # both #foo and #bar when migrating away from ruby2_keywords.
+    ruby2_keywords def bar(*args)
+      target(*args)
+    end
+
+    ruby2_keywords def foo(*args)
+      bar(*args)
+    end
+
+    foo(k: 1)
+    ```
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Fiber
+
+    * Introduce Fiber.[] and Fiber.[]= for inheritable fiber storage.
+      Introduce Fiber#storage and Fiber#storage= (experimental) for
+      getting and resetting the current storage.  Introduce
+      `Fiber.new(storage:)` for setting the storage when creating a
+      fiber. [[Feature #19078]]
+
+        Existing Thread and Fiber local variables can be tricky to use.
+        Thread-local variables are shared between all fibers, making it
+        hard to isolate, while Fiber-local variables can be hard to
+        share.  It is often desirable to define unit of execution
+        ("execution context") such that some state is shared between all
+        fibers and threads created in that context.  This is what Fiber
+        storage provides.
+
+        ```ruby
+        def log(message)
+          puts "#{Fiber[:request_id]}: #{message}"
+        end
+
+        def handle_requests
+          while request = read_request
+            Fiber.schedule do
+              Fiber[:request_id] = SecureRandom.uuid
+
+              request.messages.each do |message|
+                Fiber.schedule do
+                  log("Handling #{message}") # Log includes inherited request_id.
+                end
+              end
+            end
+          end
+        end
+        ```
+
+        You should generally consider Fiber storage for any state which
+        you want to be shared implicitly between all fibers and threads
+        created in a given context, e.g. a connection pool, a request
+        id, a logger level, environment variables, configuration, etc.
+
+* Fiber::Scheduler
+
+    * Introduce `Fiber::Scheduler#io_select` for non-blocking IO.select.
+      [[Feature #19060]]
+
+* IO
+
+    * Introduce IO#timeout= and IO#timeout which can cause
+      IO::TimeoutError to be raised if a blocking operation exceeds the
+      specified timeout. [[Feature #18630]]
+
+        ```ruby
+        STDIN.timeout = 1
+        STDIN.read # => Blocking operation timed out! (IO::TimeoutError)
+        ```
+
+    * Introduce `IO.new(..., path:)` and promote `File#path` to `IO#path`.
+      [[Feature #19036]]
+
+* Class
+
+    * Class#attached_object, which returns the object for which
+      the receiver is the singleton class. Raises TypeError if the
+      receiver is not a singleton class.
+      [[Feature #12084]]
+
+        ```ruby
+        class Foo; end
+
+        Foo.singleton_class.attached_object        #=> Foo
+        Foo.new.singleton_class.attached_object    #=> #<Foo:0x000000010491a370>
+        Foo.attached_object                        #=> TypeError: `Foo' is not a singleton class
+        nil.singleton_class.attached_object        #=> TypeError: `NilClass' is not a singleton class
+        ```
+
+* Data
+
+    * New core class to represent simple immutable value object. The class is
+      similar to Struct and partially shares an implementation, but has more
+      lean and strict API. [[Feature #16122]]
+
+        ```ruby
+        Measure = Data.define(:amount, :unit)
+        distance = Measure.new(100, 'km')            #=> #<data Measure amount=100, unit="km">
+        weight = Measure.new(amount: 50, unit: 'kg') #=> #<data Measure amount=50, unit="kg">
+        weight.with(amount: 40)                      #=> #<data Measure amount=40, unit="kg">
+        weight.amount                                #=> 50
+        weight.amount = 40                           #=> NoMethodError: undefined method `amount='
+        ```
+
+* Encoding
+
+    * Encoding#replicate has been deprecated and will be removed in 3.3. [[Feature #18949]]
+    * The dummy `Encoding::UTF_16` and `Encoding::UTF_32` encodings no longer
+      try to dynamically guess the endian based on a byte order mark.
+      Use `Encoding::UTF_16BE`/`UTF_16LE` and `Encoding::UTF_32BE`/`UTF_32LE` instead.
+      This change speeds up getting the encoding of a String. [[Feature #18949]]
+    * Limit maximum encoding set size by 256.
+      If exceeding maximum size, `EncodingError` will be raised. [[Feature #18949]]
+
+* Enumerator
+
+    * Enumerator.product has been added.  Enumerator::Product is the implementation. [[Feature #18685]]
+
+* Exception
+
+    * Exception#detailed_message has been added.
+      The default error printer calls this method on the Exception object
+      instead of #message. [[Feature #18564]]
+
+* Hash
+
+    * Hash#shift now always returns nil if the hash is
+      empty, instead of returning the default value or
+      calling the default proc. [[Bug #16908]]
+
+* Integer
+
+    * Integer#ceildiv has been added. [[Feature #18809]]
+
+* Kernel
+
+    * Kernel#binding raises RuntimeError if called from a non-Ruby frame
+      (such as a method defined in C). [[Bug #18487]]
+
+* MatchData
+
+    * MatchData#byteoffset has been added. [[Feature #13110]]
+    * MatchData#deconstruct has been added. [[Feature #18821]]
+    * MatchData#deconstruct_keys has been added. [[Feature #18821]]
+
+* Module
+
+    * Module.used_refinements has been added. [[Feature #14332]]
+    * Module#refinements has been added. [[Feature #12737]]
+    * Module#const_added has been added. [[Feature #17881]]
+    * Module#undefined_instance_methods has been added. [[Feature #12655]]
+
+* Proc
+
+    * Proc#dup returns an instance of subclass. [[Bug #17545]]
+    * Proc#parameters now accepts lambda keyword. [[Feature #15357]]
+
+* Process
+    * Added `RLIMIT_NPTS` constant to FreeBSD platform
+
+* Regexp
+
+    * The cache-based optimization is introduced.
+      Many (but not all) Regexp matching is now in linear time, which
+      will prevent regular expression denial of service (ReDoS)
+      vulnerability. [[Feature #19104]]
+
+    * Regexp.linear_time? is introduced. [[Feature #19194]]
+
+    * Regexp.new now supports passing the regexp flags not only as an Integer,
+      but also as a String.  Unknown flags raise ArgumentError.
+      Otherwise, anything other than `true`, `false`, `nil` or Integer will be warned.
+      [[Feature #18788]]
+
+    * Regexp.timeout= has been added. Also, Regexp.new new supports timeout keyword.
+      See [[Feature #17837]]
+
+* Refinement
+
+    * Refinement#refined_class has been added. [[Feature #12737]]
+
+* RubyVM::AbstractSyntaxTree
+
+    * Add `error_tolerant` option for `parse`, `parse_file` and `of`. [[Feature #19013]]
+      With this option
+
+        1. SyntaxError is suppressed
+        2. AST is returned for invalid input
+        3. `end` is complemented when a parser reaches to the end of input but `end` is insufficient
+        4. `end` is treated as keyword based on indent
+
+        ```ruby
+        # Without error_tolerant option
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY)
+        def m
+          a = 10
+          if
+        end
+        RUBY
+        # => <internal:ast>:33:in `parse': syntax error, unexpected `end' (SyntaxError)
+
+        # With error_tolerant option
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY, error_tolerant: true)
+        def m
+          a = 10
+          if
+        end
+        RUBY
+        p root # => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-4:3>
+
+        # `end` is treated as keyword based on indent
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY, error_tolerant: true)
+        module Z
+          class Foo
+            foo.
+          end
+
+          def bar
+          end
+        end
+        RUBY
+        p root.children[-1].children[-1].children[-1].children[-2..-1]
+        # => [#<RubyVM::AbstractSyntaxTree::Node:CLASS@2:2-4:5>, #<RubyVM::AbstractSyntaxTree::Node:DEFN@6:2-7:5>]
+        ```
+
+    * Add `keep_tokens` option for `parse`, `parse_file` and `of`. Add `#tokens` and `#all_tokens`
+      for RubyVM::AbstractSyntaxTree::Node [[Feature #19070]]
+
+        ```ruby
+        root = RubyVM::AbstractSyntaxTree.parse("x = 1 + 2", keep_tokens: true)
+        root.tokens # => [[0, :tIDENTIFIER, "x", [1, 0, 1, 1]], [1, :tSP, " ", [1, 1, 1, 2]], ...]
+        root.tokens.map{_1[2]}.join # => "x = 1 + 2"
+        ```
+
+* Set
+
+    * Set is now available as a built-in class without the need for `require "set"`. [[Feature #16989]]
+      It is currently autoloaded via the Set constant or a call to Enumerable#to_set.
+
+* String
+
+    * String#byteindex and String#byterindex have been added. [[Feature #13110]]
+    * Update Unicode to Version 15.0.0 and Emoji Version 15.0. [[Feature #18639]]
+      (also applies to Regexp)
+    * String#bytesplice has been added.  [[Feature #18598]]
+    * String#dedup has been added as an alias to String#-@.  [[Feature #18595]]
+
+* Struct
+
+    * A Struct class can also be initialized with keyword arguments
+      without `keyword_init: true` on Struct.new [[Feature #16806]]
+
+        ```ruby
+        Post = Struct.new(:id, :name)
+        Post.new(1, "hello") #=> #<struct Post id=1, name="hello">
+        # From Ruby 3.2, the following code also works without keyword_init: true.
+        Post.new(id: 1, name: "hello") #=> #<struct Post id=1, name="hello">
+        ```
+
+* Thread
+
+    * Thread.each_caller_location is added. [[Feature #16663]]
+
+* Thread::Queue
+
+    * Thread::Queue#pop(timeout: sec) is added. [[Feature #18774]]
+
+* Thread::SizedQueue
+
+    * Thread::SizedQueue#pop(timeout: sec) is added. [[Feature #18774]]
+    * Thread::SizedQueue#push(timeout: sec) is added. [[Feature #18944]]
+
+* Time
+
+    * Time#deconstruct_keys is added, allowing to use Time instances
+      in pattern-matching expressions [[Feature #19071]]
+
+    * Time.new now can parse a string like generated by Time#inspect
+      and return a Time instance based on the given argument.
+      [[Feature #18033]]
+
+* SyntaxError
+    * SyntaxError#path has been added.  [[Feature #19138]]
+
+* TracePoint
+
+    * TracePoint#binding now returns `nil` for `c_call`/`c_return` TracePoints.
+      [[Bug #18487]]
+    * TracePoint#enable `target_thread` keyword argument now defaults to the
+      current thread if a block is given and `target` and `target_line` keyword
+      arguments are not passed. [[Bug #16889]]
+
+* UnboundMethod
+
+    * `UnboundMethod#==` returns `true` if the actual method is same. For example,
+      `String.instance_method(:object_id) == Array.instance_method(:object_id)`
+      returns `true`. [[Feature #18798]]
+
+    * `UnboundMethod#inspect` does not show the receiver of `instance_method`.
+      For example `String.instance_method(:object_id).inspect` returns
+      `"#<UnboundMethod: Kernel#object_id()>"`
+      (was `"#<UnboundMethod: String(Kernel)#object_id()>"`).
+
+* GC
+
+    * Expose `need_major_gc` via `GC.latest_gc_info`. [GH-6791]
+
+* ObjectSpace
+
+    * `ObjectSpace.dump_all` dump shapes as well. [GH-6868]
+
+## Stdlib updates
+
+* Bundler
+
+    * Bundler now uses [PubGrub] resolver instead of [Molinillo] for performance improvement.
+    * Add --ext=rust support to bundle gem for creating simple gems with Rust extensions.
+      [[GH-rubygems-6149]]
+    * Make cloning git repos faster [[GH-rubygems-4475]]
+
+* RubyGems
+
+    * Add mswin support for cargo builder. [[GH-rubygems-6167]]
+
+* CGI
+
+    * `CGI.escapeURIComponent` and `CGI.unescapeURIComponent` are added.
+      [[Feature #18822]]
+
+* Coverage
+
+    * `Coverage.setup` now accepts `eval: true`. By this, `eval` and related methods are
+      able to generate code coverage. [[Feature #19008]]
+
+    * `Coverage.supported?(mode)` enables detection of what coverage modes are
+      supported. [[Feature #19026]]
+
+* Date
+
+    * Added `Date#deconstruct_keys` and `DateTime#deconstruct_keys` same as [[Feature #19071]]
+
+* ERB
+
+    * `ERB::Util.html_escape` is made faster than `CGI.escapeHTML`.
+        * It no longer allocates a String object when no character needs to be escaped.
+        * It skips calling `#to_s` method when an argument is already a String.
+        * `ERB::Escape.html_escape` is added as an alias to `ERB::Util.html_escape`,
+          which has not been monkey-patched by Rails.
+    * `ERB::Util.url_encode` is made faster using `CGI.escapeURIComponent`.
+    * `-S` option is removed from `erb` command.
+
+* FileUtils
+
+    * Add FileUtils.ln_sr method and `relative:` option to FileUtils.ln_s.
+      [[Feature #18925]]
+
+* IRB
+
+    * debug.gem integration commands have been added: `debug`, `break`, `catch`,
+      `next`, `delete`, `step`, `continue`, `finish`, `backtrace`, `info`
+        * They work even if you don't have `gem "debug"` in your Gemfile.
+        * See also: [What's new in Ruby 3.2's IRB?](https://st0012.dev/whats-new-in-ruby-3-2-irb)
+    * More Pry-like commands and features have been added.
+        * `edit` and `show_cmds` (like Pry's `help`) are added.
+        * `ls` takes `-g` or `-G` option to filter out outputs.
+        * `show_source` is aliased from `$` and accepts unquoted inputs.
+        * `whereami` is aliased from `@`.
+
+* Net::Protocol
+
+    * Improve `Net::BufferedIO` performance. [[GH-net-protocol-14]]
+
+* Pathname
+
+    * Added `Pathname#lutime`. [[GH-pathname-20]]
+
+* Socket
+
+    * Added the following constants for supported platforms.
+        * `SO_INCOMING_CPU`
+        * `SO_INCOMING_NAPI_ID`
+        * `SO_RTABLE`
+        * `SO_SETFIB`
+        * `SO_USER_COOKIE`
+        * `TCP_KEEPALIVE`
+        * `TCP_CONNECTION_INFO`
+
+* SyntaxSuggest
+
+    * The feature of `syntax_suggest` formerly `dead_end` is integrated in Ruby.
+      [[Feature #18159]]
+
+* UNIXSocket
+

+
+## Supported platforms
+
+* WebAssembly/WASI is added. See [wasm/README.md] and [ruby.wasm] for more details. [[Feature #18462]]
+
+## Compatibility issues
+
+* `String#to_c` currently treat a sequence of underscores as an end of Complex
+  string. [[Bug #19087]]
+
+* Now `ENV.clone` raises `TypeError` as well as `ENV.dup` [[Bug #17767]]
+
+### Removed constants
+
+The following deprecated constants are removed.
+
+* `Fixnum` and `Bignum` [[Feature #12005]]
+* `Random::DEFAULT` [[Feature #17351]]
+* `Struct::Group`
+* `Struct::Passwd`
+
+### Removed methods
+
+The following deprecated methods are removed.
+
+* `Dir.exists?` [[Feature #17391]]
+* `File.exists?` [[Feature #17391]]
+* `Kernel#=~` [[Feature #15231]]
+* `Kernel#taint`, `Kernel#untaint`, `Kernel#tainted?`
+  [[Feature #16131]]
+* `Kernel#trust`, `Kernel#untrust`, `Kernel#untrusted?`
+  [[Feature #16131]]
+* `Method#public?`, `Method#private?`, `Method#protected?`,
+  `UnboundMethod#public?`, `UnboundMethod#private?`, `UnboundMethod#protected?`
+  [[Bug #18729]] [[Bug #18751]] [[Bug #18435]]
+
+### Source code incompatibility of extension libraries
+
+* Extension libraries provide PRNG, subclasses of Random, need updates.
+  See [PRNG update] below for more information. [[Bug #19100]]
+
+### Error printer
+
+* Ruby no longer escapes control characters and backslashes in an
+  error message. [[Feature #18367]]
+
+### Constant lookup when defining a class/module
+
+* When defining a class/module directly under the Object class by class/module
+  statement, if there is already a class/module defined by `Module#include`
+  with the same name, the statement was handled as "open class" in Ruby 3.1 or before.
+  Since Ruby 3.2, a new class is defined instead. [[Feature #18832]]
+
+## Stdlib compatibility issues
+
+* Psych no longer bundles libyaml sources.
+  And also Fiddle no longer bundles libffi sources.
+  Users need to install the libyaml/libffi library themselves via the package
+  manager like apt, yum, brew, etc.
+
+    Psych and fiddle supported the static build with specific version of libyaml
+    and libffi sources. You can build psych with libyaml-0.2.5 like this.
+
+    ```bash
+    $ ./configure --with-libyaml-source-dir=/path/to/libyaml-0.2.5
+    ```
+
+    And you can build fiddle with libffi-3.4.4 like this.
+
+    ```bash
+    $ ./configure --with-libffi-source-dir=/path/to/libffi-3.4.4
+    ```
+
+    [[Feature #18571]]
+
+* Check cookie name/path/domain characters in `CGI::Cookie`. [[CVE-2021-33621]]
+
+* `URI.parse` return empty string in host instead of nil. [[sec-156615]]
+
+## C API updates
+
+### Updated C APIs
+
+The following APIs are updated.
+
+* PRNG update
+
+    `rb_random_interface_t` in ruby/random.h updated and versioned.
+    Extension libraries which use this interface and built for older
+    versions need to rebuild with adding `init_int32` function.
+
+### Added C APIs
+
+* `VALUE rb_hash_new_capa(long capa)` was added to created hashes with the desired capacity.
+* `rb_internal_thread_add_event_hook` and `rb_internal_thread_add_event_hook` were added to instrument threads scheduling.
+  The following events are available:
+    * `RUBY_INTERNAL_THREAD_EVENT_STARTED`
+    * `RUBY_INTERNAL_THREAD_EVENT_READY`
+    * `RUBY_INTERNAL_THREAD_EVENT_RESUMED`
+    * `RUBY_INTERNAL_THREAD_EVENT_SUSPENDED`
+    * `RUBY_INTERNAL_THREAD_EVENT_EXITED`
+* `rb_debug_inspector_current_depth` and `rb_debug_inspector_frame_depth` are added for debuggers.
+
+### Removed C APIs
+
+The following deprecated APIs are removed.
+
+* `rb_cData` variable.
+* "taintedness" and "trustedness" functions. [[Feature #16131]]
+
+## Implementation improvements
+
+* Fixed several race conditions in Kernel#autoload. [[Bug #18782]]
+* Cache invalidation for expressions referencing constants is now
+  more fine-grained. `RubyVM.stat(:global_constant_state)` was
+  removed because it was closely tied to the previous caching scheme
+  where setting any constant invalidates all caches in the system.
+  New keys, `:constant_cache_invalidations` and `:constant_cache_misses`,
+  were introduced to help with use cases for `:global_constant_state`.
+  [[Feature #18589]]
+* The cache-based optimization for Regexp matching is introduced.
+  [[Feature #19104]]
+* [Variable Width Allocation](https://shopify.engineering/ruby-variable-width-allocation)
+  is now enabled by default. [[Feature #18239]]
+* Added a new instance variable caching mechanism, called object shapes, which
+  improves inline cache hits for most objects and allows us to generate very
+  efficient JIT code. Objects whose instance variables are defined in a
+  consistent order will see the most performance benefits.
+  [[Feature #18776]]
+* Speed up marking instruction sequences by using a bitmap to find "markable"
+  objects.  This change results in faster major collections.
+  [[Feature #18875]]
+
+## JIT
+
+### YJIT
+
+* YJIT is no longer experimental
+    * Has been tested on production workloads for over a year and proven to be quite stable.
+* YJIT now supports both x86-64 and arm64/aarch64 CPUs on Linux, MacOS, BSD and other UNIX platforms.
+    * This release brings support for Mac M1/M2, AWS Graviton and Raspberry Pi 4.
+* Building YJIT now requires Rust 1.58.0+. [[Feature #18481]]
+    * In order to ensure that CRuby is built with YJIT, please install `rustc` >= 1.58.0
+      before running `./configure`
+    * Please reach out to the YJIT team should you run into any issues.
+* Physical memory for JIT code is lazily allocated. Unlike Ruby 3.1,
+  the RSS of a Ruby process is minimized because virtual memory pages
+  allocated by `--yjit-exec-mem-size` will not be mapped to physical
+  memory pages until actually utilized by JIT code.
+* Introduce Code GC that frees all code pages when the memory consumption
+  by JIT code reaches `--yjit-exec-mem-size`.
+    * `RubyVM::YJIT.runtime_stats` returns Code GC metrics in addition to
+      existing `inline_code_size` and `outlined_code_size` keys:
+      `code_gc_count`, `live_page_count`, `freed_page_count`, and `freed_code_size`.
+* Most of the statistics produced by `RubyVM::YJIT.runtime_stats` are now available in release builds.
+    * Simply run ruby with `--yjit-stats` to compute and dump stats (incurs some run-time overhead).
+* YJIT is now optimized to take advantage of object shapes. [[Feature #18776]]
+* Take advantage of finer-grained constant invalidation to invalidate less code when defining new constants. [[Feature #18589]]
+* The default `--yjit-exec-mem-size` is changed to 64 (MiB).
+* The default `--yjit-call-threshold` is changed to 30.
+
+### MJIT
+
+* The MJIT compiler is re-implemented in Ruby as `ruby_vm/mjit/compiler`.
+* MJIT compiler is executed under a forked Ruby process instead of
+  doing it in a native thread called MJIT worker. [[Feature #18968]]
+    * As a result, Microsoft Visual Studio (MSWIN) is no longer supported.
+* MinGW is no longer supported. [[Feature #18824]]
+* Rename `--mjit-min-calls` to `--mjit-call-threshold`.
+* Change default `--mjit-max-cache` back from 10000 to 100.

-* What's Ruby
-
-Ruby is the interpreted scripting language for quick and
-easy object-oriented programming.  It has many features to
-process text files and to do system management tasks (as in
-Perl).  It is simple, straight-forward, and extensible.
-
-
-* Features of Ruby
-
-  + Simple Syntax
-  + *Normal* Object-Oriented features(ex. class, method calls)
-  + *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
-  + Operator Overloading
-  + Exception Handling
-  + Iterators and Closures
-  + Garbage Collection
-  + Dynamic Loading of Object files(on some architecture)
-  + Highly Portable(works on many UNIX machines, and on DOS,
-    Windows, Mac, BeOS etc.)
-
-
-* How to get Ruby
-
-The Ruby distribution can be found on:
-
-  ftp://ftp.ruby-lang.org/pub/ruby/
-
-You can get it by anonymous CVS.  How to check out is:
-
-  $ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/src login
-  (Logging in to anonymous@cvs.ruby-lang.org)
-  CVS password: anonymous
-  $ cvs -z4 -d :pserver:anonymous@cvs.ruby-lang.org:/src checkout ruby
-
-
-* Ruby home-page
-
-The URL of the Ruby home-page is:
-
-   http://www.ruby-lang.org/
-
-
-* Mailing list
-
-There is a mailing list to talk about Ruby.
-To subscribe this list, please send the following phrase
-
-	subscribe YourFirstName YourFamilyName
-e.g.
-        subscribe Joseph Smith
-
-in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
-
-
-* How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-  1. If ./configure does not exist or is older than configure.in,
-     run autoconf to (re)generate configure.
-
-  2. Run ./configure, which will generate config.h and Makefile.
-
-  3. Edit defines.h if you need.  Probably this step will not need.
-
-  4. Remove comment mark(#) before the module names from ext/Setup (or
-     add module names if not present), if you want to link modules
-     statically.
-
-     If you don't want to compile non static extension modules
-     (probably on architectures which does not allow dynamic loading),
-     remove comment mark from the line "#option nodynamic" in
-     ext/Setup.
-
-  5. Run make.
-
-  6. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  7. Run 'make install'
-
-     You may have to be a super user to install ruby.
-
-If you fail to compile ruby, please send the detailed error report with
-the error log and machine/OS type, to help others.
-
-
-* Copying
-
-See the file COPYING.
-
-
-* The Author
-
-Feel free to send comments and bug reports to the author.  Here is the 
-author's latest mail address:

-This document explains how to make extension libraries for Ruby.
-
-1. Basic knowledge
-
-In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have a static type, and data themselves have
-types, so data will need to be converted between the languages.
-
-Data in Ruby are represented by C type `VALUE'.  Each VALUE data has
-its data-type.
-
-To retrieve C data from a VALUE, you need to:
-
- (1) Identify the VALUE's data type
- (2) Convert the VALUE into C data
-
-Converting to the wrong data type may cause serious problems.
-
-
-1.1 Data-types
-
-The Ruby interpreter has the following data types:
-
-	T_NIL		nil
-	T_OBJECT	ordinary object
-	T_CLASS		class
-	T_MODULE	module
-	T_FLOAT		floating point number
-	T_STRING	string
-	T_REGEXP	regular expression
-	T_ARRAY		array
-	T_FIXNUM	Fixnum(31bit integer)
-	T_HASH		associative array
-	T_STRUCT	(Ruby) structure
-	T_BIGNUM	multi precision integer
-	T_FILE		IO
-	T_TRUE		true
-	T_FALSE		false
-	T_DATA		data
-	T_SYMBOL        symbol
-
-In addition, there are several other types used internally:
-
-	T_ICLASS
-	T_MATCH
-	T_UNDEF
-	T_VARMAP
-	T_SCOPE
-	T_NODE
-
-Most of the types are represented by C structures.
-
-1.2 Check Data Type of the VALUE
-
-The macro TYPE() defined in ruby.h shows the data type of the VALUE.
-TYPE() returns the constant number T_XXXX described above.  To handle
-data types, your code will look something like this:
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* process Fixnum */
-      break;
-    case T_STRING:
-      /* process String */
-      break;
-    case T_ARRAY:
-      /* process Array */
-      break;
-    default:
-      /* raise exception */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-There is the data-type check function
-
-  void Check_Type(VALUE value, int type)
-
-which raises an exception if the VALUE does not have the type specified.
-
-There are also faster check macros for fixnums and nil.
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-1.3 Convert VALUE into C data
-
-The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
-respectively.  They are singletons for the data type.
-
-The T_FIXNUM data is a 31bit length fixed integer (63bit length on
-some machines), which can be convert to a C integer by using the
-FIX2INT() macro.  There is also NUM2INT() which converts any Ruby
-numbers into C integers.  The NUM2INT() macro includes a type check, so
-an exception will be raised if the conversion failed.  NUM2DBL() can
-be used to retrieve the double float value in same way.
-
-To get char* from a VALUE, version 1.7 recommend to use new macros
-StringValue() and StringValuePtr().  StringValue(var) replaces var's
-value to the result of "var.to_str()".  StringValuePtr(var) does same
-replacement and returns char* representation of var.  These macros
-will skip the replacement if var is a String.  Notice that the macros
-requires to take only lvalue as their argument, to change the value
-of var in the replacement. 
-
-In version 1.6 or earlier, STR2CSTR() was used to do same thing
-but now it is obsoleted in version 1.7 because of STR2CSTR() has
-a risk of dangling pointer problem in to_str() impliclit conversion.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. The VALUE of the type which has corresponding structure
-can be cast to retrieve the pointer to the struct.  The casting macro
-will be of the form RXXXX for each data type; for instance, RARRAY(obj). 
-See "ruby.h".
-
-For example, `RSTRING(str)->len' is the way to get the size of the
-Ruby String object.  The allocated region can be accessed by
-`RSTRING(str)->ptr'.  For arrays, use `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible for the result.  This ends up being the cause of interesting
-bugs.
-
-1.4 Convert C data into VALUE
-
-To convert C data to Ruby values:
-
-  * FIXNUM
-
-    left shift 1 bit, and turn on LSB.
-
-  * Other pointer values
-
-    cast to VALUE.
-
-You can determine whether a VALUE is pointer or not by checking its LSB.  
-
-Notice Ruby does not allow arbitrary pointer values to be a VALUE.  They
-should be pointers to the structures which Ruby knows about.  The known
-structures are defined in <ruby.h>.
-
-To convert C numbers to Ruby values, use these macros.
-
-  INT2FIX()	for integers within 31bits.
-  INT2NUM()	for arbitrary sized integer.
-
-INT2NUM() converts an integer into a Bignum if it is out of the FIXNUM
-range, but is a bit slower.
-
-1.5 Manipulating Ruby data
-
-As I already mentioned, it is not recommended to modify an object's internal
-structure.  To manipulate objects, use the functions supplied by the Ruby
-interpreter. Some (not all) of the useful functions are listed below:
-
- String functions
-
-  rb_str_new(const char *ptr, long len)
-
-    Creates a new Ruby string.
-
-  rb_str_new2(const char *ptr)
-
-    Creates a new Ruby string from a C string.  This is equivalent to
-    rb_str_new(ptr, strlen(ptr)).
-
-  rb_tainted_str_new(const char *ptr, long len)
-
-    Creates a new tainted Ruby string.  Strings from external data
-    sources should be tainted.
-
-  rb_tainted_str_new2(const char *ptr)
-
-    Creates a new tainted Ruby string from a C string.
-
-  rb_str_cat(VALUE str, const char *ptr, long len)
-
-    Appends len bytes of data from ptr to the Ruby string.
-
- Array functions
-
-  rb_ary_new()
-
-    Creates an array with no elements.
-
-  rb_ary_new2(long len)
-
-    Creates an array with no elements, allocating internal buffer
-    for len elements.
-
-  rb_ary_new3(long n, ...)
-
-    Creates an n-element array from the arguments.
-
-  rb_ary_new4(long n, VALUE *elts)
-
-    Creates an n-element array from a C array.
-
-  rb_ary_push(VALUE ary, VALUE val)
-  rb_ary_pop(VALUE ary)
-  rb_ary_shift(VALUE ary)
-  rb_ary_unshift(VALUE ary, VALUE val)
-
-    Array operations.  The first argument to each functions must be an 
-    array.  They may dump core if other types given.
-
-2. Extending Ruby with C
-
-2.1 Addding new features to Ruby
-
-You can add new features (classes, methods, etc.) to the Ruby
-interpreter.  Ruby provides APIs for defining the following things:
-
- * Classes, Modules
- * Methods, Singleton Methods
- * Constants
-
-2.1.1 Class/module definition
-
-To define a class or module, use the functions below:
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-These functions return the newly created class or module.  You may
-want to save this reference into a variable to use later.
-
-To define nested classes or modules, use the functions below:
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-2.1.2 Method/singleton method definition
-
-To define methods or singleton methods, use these functions:
-
-  void rb_define_method(VALUE klass, const char *name, 
-		        VALUE (*func)(), int argc)
-
-  void rb_define_singleton_method(VALUE object, const char *name, 
-			          VALUE (*func)(), int argc)
-
-The `argc' represents the number of the arguments to the C function,
-which must be less than 17.  But I believe you don't need that much. :-)
-
-If `argc' is negative, it specifies the calling sequence, not number of
-the arguments.  
-
-If argc is -1, the function will be called as:
-
-  VALUE func(int argc, VALUE *argv, VALUE obj)
-
-where argc is the actual number of arguments, argv is the C array of
-the arguments, and obj is the receiver.
-
-If argc is -2, the arguments are passed in a Ruby array. The function
-will be called like:
-
-  VALUE func(VALUE obj, VALUE args)
-
-where obj is the receiver, and args is the Ruby array containing
-actual arguments.
-
-There are two more functions to define methods.  One is to define
-private methods:
-
-  void rb_define_private_method(VALUE klass, const char *name, 
-			        VALUE (*func)(), int argc)
-
-The other is to define module functions, which are private AND singleton
-methods of the module.  For example, sqrt is the module function
-defined in Math module.  It can be call in the form like:
-
-  Math.sqrt(4)
-
-or
-
-  include Math
-  sqrt(4)
-
-To define module functions, use:
-
-  void rb_define_module_function(VALUE module, const char *name, 
-				 VALUE (*func)(), int argc)
-
-Oh, in addition, function-like methods, which are private methods defined
-in the Kernel module, can be defined using:
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-To define alias to the method,
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-To define and undefine the `allocate' class method,
-
-  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
-  void rb_undef_alloc_func(VALUE klass);
-
-func have to take the klass as the argument and return a newly
-allocated instance.  This instance should be empty as possible,
-without any expensive (including external) resources.
-
-2.1.3 Constant definition
-
-We have 2 functions to define constants:
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-The former is to define a constant under specified class/module.  The
-latter is to define a global constant.
-
-2.2 Use Ruby features from C
-
-There are several ways to invoke Ruby's features from C code.
-
-2.2.1 Evaluate Ruby Programs in a String
-
-The easiest way to use Ruby's functionality from a C program is to
-evaluate the string as Ruby program.  This function will do the job.
-
-  VALUE rb_eval_string(const char *str)
-
-Evaluation is done under the current context, thus current local variables
-of the innermost method (which is defined by Ruby) can be accessed.
-
-2.2.2 ID or Symbol
-
-You can invoke methods directly, without parsing the string.  First I need
-to explain about ID.  ID is the integer number to represent Ruby's
-identifiers such as variable names.  The Ruby data type corresponding to ID
-is Symbol.  It can be accessed from Ruby in the form:
-
- :Identifier
-
-You can get the ID value from a string within C code by using
-
-  rb_intern(const char *name)
-
-You can retrieve ID from Ruby object (Symbol or String) given as an
-argument by using
-
-  rb_to_id(VALUE symbol)
-
-You can convert C ID to Ruby Symbol by using
-
-  VALUE ID2SYM(ID id)
-
-and to convert Ruby Symbol object to ID, use
-
-  ID SYM2ID(VALUE symbol)
-
-2.2.3 Invoke Ruby method from C
-
-To invoke methods directly, you can use the function below
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-This function invokes a method on the recv, with the method name
-specified by the symbol mid.
-
-2.2.4 Accessing the variables and constants
-
-You can access class variables and instance variables using access
-functions.  Also, global variables can be shared between both environments.
-There's no way to access Ruby's local variables.
-
-The functions to access/modify instance variables are below:
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-id must be the symbol, which can be retrieved by rb_intern().
-
-To access the constants of the class/module:
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-See 2.1.3 for defining new constant.
-
-3. Information sharing between Ruby and C
-
-3.1 Ruby constants that C can be accessed from C
-
-The following Ruby constants can be referred from C.
-
-  Qtrue
-  Qfalse
-
-Boolean values.  Qfalse is false in C also (i.e. 0).
-
-  Qnil
-
-Ruby nil in C scope.
-
-3.2 Global variables shared between C and Ruby
-
-Information can be shared between the two environments using shared global
-variables.  To define them, you can use functions listed below:
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-This function defines the variable which is shared by both environments.
-The value of the global variable pointed to by `var' can be accessed
-through Ruby's global variable named `name'.
-
-You can define read-only (from Ruby, of course) variables using the
-function below.
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-You can defined hooked variables.  The accessor functions (getter and
-setter) are called on access to the hooked variables.
-
-  void rb_define_hooked_variable(constchar *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-If you need to supply either setter or getter, just supply 0 for the
-hook you don't need.  If both hooks are 0, rb_define_hooked_variable()
-works just like rb_define_variable().
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-This function defines a Ruby global variable without a corresponding C
-variable.  The value of the variable will be set/get only by hooks.
-
-The prototypes of the getter and setter functions are as follows:
-
-  (*getter)(ID id, void *data, struct global_entry* entry);
-  (*setter)(VALUE val, ID id, void *data, struct global_entry* entry);
-
-3.3 Encapsulate C data into Ruby object
-
-To wrap and objectify a C pointer as a Ruby object (so called
-DATA), use Data_Wrap_Struct().
-
-  Data_Wrap_Struct(klass, mark, free, ptr)
-
-Data_Wrap_Struct() returns a created DATA object.  The klass argument
-is the class for the DATA object.  The mark argument is the function
-to mark Ruby objects pointed by this data.  The free argument is the
-function to free the pointer allocation.  If this is -1, the pointer
-will be just freed.  The functions mark and free will be called from
-garbage collector.
-
-You can allocate and wrap the structure in one step.
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro returns an allocated Data object, wrapping the pointer to
-the structure, which is also allocated.  This macro works like:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-Arguments klass, mark, and free work like their counterparts in
-Data_Wrap_Struct().  A pointer to the allocated structure will be
-assigned to sval, which should be a pointer of the type specified.
-
-To retrieve the C pointer from the Data object, use the macro
-Data_Get_Struct().
-
-  Data_Get_Struct(obj, type, sval)
-
-A pointer to the structure will be assigned to the variable sval.
-
-See the example below for details. 
-
-4. Example - Creating dbm extension
-
-OK, here's the example of making an extension library.  This is the
-extension to access DBMs.  The full source is included in the ext/
-directory in the Ruby's source tree.
-
-(1) make the directory
-
-  % mkdir ext/dbm
-
-Make a directory for the extension library under ext directory.
-
-(2) design the library
-
-You need to design the library features, before making it.
-
-(3) write C code.
-
-You need to write C code for your extension library.  If your library
-has only one source file, choosing ``LIBRARY.c'' as a file name is
-preferred.  On the other hand, in case your library has multiple source
-files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
-with an intermediate file ``LIBRARY.o'' on some platforms.
-
-Ruby will execute the initializing function named ``Init_LIBRARY'' in
-the library.  For example, ``Init_dbm()'' will be executed when loading
-the library.
-
-Here's the example of an initializing function.
-
---
-Init_dbm()
-{
-    /* define DBM class */
-    cDBM = rb_define_class("DBM", rb_cObject);
-    /* DBM includes Enumerate module */
-    rb_include_module(cDBM, rb_mEnumerable);
-
-    /* DBM has class method open(): arguments are received as C array */
-    rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-
-    /* DBM instance method close(): no args */
-    rb_define_method(cDBM, "close", fdbm_close, 0);
-    /* DBM instance method []: 1 argument */
-    rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-		:
-
-    /* ID for a instance variable to store DBM data */
-    id_dbm = rb_intern("dbm");
-}
---
-
-The dbm extension wraps the dbm struct in the C environment using 
-Data_Make_Struct.
-
---
-struct dbmdata {
-    int  di_size;
-    DBM *di_dbm;
-};
-
-
-obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
---
-
-This code wraps the dbmdata structure into a Ruby object.  We avoid wrapping
-DBM* directly, because we want to cache size information.
-
-To retrieve the dbmdata structure from a Ruby object, we define the
-following macro:
-
---
-#define GetDBM(obj, dbmp) {\
-    Data_Get_Struct(obj, struct dbmdata, dbmp);\
-    if (dbmp->di_dbm == 0) closed_dbm();\
-}
---
-
-This sort of complicated macro does the retrieving and close checking for
-the DBM.
-
-There are three kinds of way to receive method arguments.  First,
-methods with a fixed number of arguments receive arguments like this:
-
---
-static VALUE
-fdbm_delete(obj, keystr)
-    VALUE obj, keystr;
-{
-	:
-}
---
-
-The first argument of the C function is the self, the rest are the
-arguments to the method.
-
-Second, methods with an arbitrary number of arguments receive
-arguments like this:
-
---
-static VALUE
-fdbm_s_open(argc, argv, klass)
-    int argc;
-    VALUE *argv;
-    VALUE klass;
-{
-	:
-    if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-	mode = 0666;		/* default value */
-    }
-	:
-}
---
-
-The first argument is the number of method arguments, the second
-argument is the C array of the method arguments, and the third
-argument is the receiver of the method.
-
-You can use the function rb_scan_args() to check and retrieve the
-arguments.  For example, "11" means that the method requires at least one
-argument, and at most receives two arguments.
-
-Methods with an arbitrary number of arguments can receive arguments
-by Ruby's array, like this:
-
---
-static VALUE
-fdbm_indexes(obj, args)
-    VALUE obj, args;
-{
-	:
-}
---
-
-The first argument is the receiver, the second one is the Ruby array
-which contains the arguments to the method.
-
-** Notice
-
-GC should know about global variables which refer to Ruby's objects, but
-are not exported to the Ruby world.  You need to protect them by
-
-  void rb_global_variable(VALUE *var)
-
-(4) prepare extconf.rb
-
-If the file named extconf.rb exists, it will be executed to generate
-Makefile.
-
-extconf.rb is the file for check compilation conditions etc.  You
-need to put
-
-  require 'mkmf'
-
-at the top of the file.  You can use the functions below to check
-various conditions.
-
-  have_library(lib, func): check whether library containing function exists.
-  have_func(func, header): check whether function exists
-  have_header(header): check whether header file exists
-  create_makefile(target): generate Makefile
-
-The value of the variables below will affect the Makefile.
-
-  $CFLAGS: included in CFLAGS make variable (such as -O)
-  $CPPFLAGS: included in CPPFLAGS make variable (such as -I, -D)
-  $LDFLAGS: included in LDFLAGS make variable (such as -L)
-  $objs: list of object file names
-
-In normal, object files list is automatically generated by searching
-source files, but you need directs them explicitly if any sources will
-be generated while building.
-
-If a compilation condition is not fulfilled, you should not call
-``create_makefile''.  The Makefile will not generated, compilation will
-not be done.
-
-(5) prepare depend (optional)
-
-If the file named depend exists, Makefile will include that file to
-check dependencies.  You can make this file by invoking
-
-  % gcc -MM *.c > depend
-
-It's no harm.  Prepare it.
-
-(6) generate Makefile
-
-Try generating the Makefile by:
-
-  ruby extconf.rb
-
-You don't need this step if you put the extension library under the ext
-directory of the ruby source tree.  In that case, compilation of the
-interpreter will do this step for you.
-
-(7) make
-
-Type
-
-  make
-
-to compile your extension.  You don't need this step either if you have
-put extension library under the ext directory of the ruby source tree.
-
-(8) debug
-
-You may need to rb_debug the extension.  Extensions can be linked
-statically by the adding directory name in the ext/Setup file so that
-you can inspect the extension with the debugger.
-
-(9) done, now you have the extension library
-
-You can do anything you want with your library.  The author of Ruby
-will not claim any restrictions on your code depending on the Ruby API.
-Feel free to use, modify, distribute or sell your program.

-Appendix B. Ruby extension API reference
-
-** Types
-
- VALUE
-
-The type for the Ruby object.  Actual structures are defined in ruby.h,
-such as struct RString, etc.  To refer the values in structures, use
-casting macros like RSTRING(obj).
-
-** Variables and constants
-
- Qnil
-
-const: nil object
-
- Qtrue
-
-const: true object(default true value)
-
- Qfalse
-
-const: false object
-
-** C pointer wrapping
-
- Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval)
-
-Wrap a C pointer into a Ruby object.  If object has references to other
-Ruby objects, they should be marked by using the mark function during
-the GC process.  Otherwise, mark should be 0.  When this object is no
-longer referred by anywhere, the pointer will be discarded by free
-function.
-
- Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro allocates memory using malloc(), assigns it to the variable
-sval, and returns the DATA encapsulating the pointer to memory region.
-
- Data_Get_Struct(data, type, sval)
-
-This macro retrieves the pointer value from DATA, and assigns it to
-the variable sval. 
-
-** Checking data types

-
-** defining class/module
-
- VALUE rb_define_class(const char *name, VALUE super)
-
-Defines a new Ruby class as a subclass of super.
-
- VALUE rb_define_class_under(VALUE module, const char *name, VALUE super)
-
-Creates a new Ruby class as a subclass of super, under the module's
-namespace.
-
- VALUE rb_define_module(const char *name)
-
-Defines a new Ruby module.
-
- VALUE rb_define_module_under(VALUE module, const char *name)
-
-Defines a new Ruby module under the module's namespace.
-
- void rb_include_module(VALUE klass, VALUE module)
-
-Includes module into class.  If class already includes it, just
-ignored.
-
- void rb_extend_object(VALUE object, VALUE module)
-
-Extend the object with the module's attributes.
-
-** Defining Global Variables
-
- void rb_define_variable(const char *name, VALUE *var)
-
-Defines a global variable which is shared between C and Ruby.  If name
-contains a character which is not allowed to be part of the symbol,
-it can't be seen from Ruby programs.
-
- void rb_define_readonly_variable(const char *name, VALUE *var)
-
-Defines a read-only global variable.  Works just like
-rb_define_variable(), except defined variable is read-only.
-
- void rb_define_virtual_variable(const char *name,
-				 VALUE (*getter)(), VALUE (*setter)())
-
-Defines a virtual variable, whose behavior is defined by a pair of C
-functions.  The getter function is called when the variable is
-referred.  The setter function is called when the value is set to the
-variable.  The prototype for getter/setter functions are:
-
-	VALUE getter(ID id)
-	void setter(VALUE val, ID id)
-
-The getter function must return the value for the access.
-
- void rb_define_hooked_variable(const char *name, VALUE *var,
-				VALUE (*getter)(), VALUE (*setter)())
-
-Defines hooked variable.  It's a virtual variable with a C variable.

-
-	VALUE getter(ID id, VALUE *var)
-
-returning a new value.  The setter is called as
-
-	void setter(VALUE val, ID id, VALUE *var)

-
-** Method Definition
-
- rb_define_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a method for the class.  func is the function pointer.  argc
-is the number of arguments.  if argc is -1, the function will receive
-3 arguments: argc, argv, and self.  if argc is -2, the function will
-receive 2 arguments, self and args, where args is a Ruby array of
-the method arguments.
-
- rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a private method for the class.  Arguments are same as
-rb_define_method().

- rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a singleton method.  Arguments are same as rb_define_method().
-
- rb_scan_args(int argc, VALUE *argv, const char *fmt, ...)
-
-Retrieve argument from argc, argv.  The fmt is the format string for
-the arguments, such as "12" for 1 non-optional argument, 2 optional
-arguments.  If `*' appears at the end of fmt, it means the rest of
-the arguments are assigned to the corresponding variable, packed in
-an array.
-
-** Invoking Ruby method
-
- VALUE rb_funcall(VALUE recv, ID mid, int narg, ...)
-
-Invokes a method.  To retrieve mid from a method name, use rb_intern().
-
- VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
-
-Invokes a method, passing arguments by an array of values.
-
- VALUE rb_eval_string(const char *str)
-
-Compiles and executes the string as a Ruby program.
-
- ID rb_intern(const char *name)
-
-Returns ID corresponding to the name.
-
- char *rb_id2name(ID id)
-
-Returns the name corresponding ID.
-
- char *rb_class2name(VALUE klass)
-
-Returns the name of the class.
-
- int rb_respond_to(VALUE object, ID id)
-
-Returns true if the object responds to the message specified by id.
-
-** Instance Variables
-
- VALUE rb_iv_get(VALUE obj, const char *name)
-
-Retrieve the value of the instance variable.  If the name is not
-prefixed by `@', that variable shall be inaccessible from Ruby.
-
- VALUE rb_iv_set(VALUE obj, const char *name, VALUE val)
-
-Sets the value of the instance variable.
-
-** Control Structure
-
- VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, supplying func2 as the block.  func1 will be
-called with the argument arg1.  func2 receives the value from yield as
-the first argument, arg2 as the second argument.
- 
- VALUE rb_yield(VALUE val)
-
-Evaluates the block with value val.
-
- VALUE rb_rescue(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, with arg1 as the argument.  If an exception
-occurs during func1, it calls func2 with arg2 as the argument.  The
-return value of rb_rescue() is the return value from func1 if no
-exception occurs, from func2 otherwise.
-
- VALUE rb_ensure(VALUE (*func1)(), void *arg1, void (*func2)(), void *arg2)
-
-Calls the function func1 with arg1 as the argument, then calls func2
-with arg2 if execution terminated.  The return value from
-rb_ensure() is that of func1.
-
-** Exceptions and Errors
-
- void rb_warn(const char *fmt, ...)
-
-Prints a warning message according to a printf-like format.
-
- void rb_warning(const char *fmt, ...)
-
-Prints a warning message according to a printf-like format, if
-$VERBOSE is true.
-
-void rb_raise(rb_eRuntimeError, const char *fmt, ...)
-
-Raises RuntimeError.  The fmt is a format string just like printf().
-
- void rb_raise(VALUE exception, const char *fmt, ...)
-
-Raises a class exception.  The fmt is a format string just like printf().
-
- void rb_fatal(const char *fmt, ...)
-
-Raises a fatal error, terminates the interpreter.  No exception handling
-will be done for fatal errors, but ensure blocks will be executed.
-
- void rb_bug(const char *fmt, ...)
-
-Terminates the interpreter immediately.  This function should be
-called under the situation caused by the bug in the interpreter.  No
-exception handling nor ensure execution will be done.
-

+# Rubyとは
+
+Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です． Rubyは純粋なオブジェクト指向言語として設計されているので，
+オブジェクト指向プログラミングを手軽に行う事が出来ます．もちろん普通の手続き型のプログラミングも可能です．
+
+Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力です．さらにシンプルな文法と，
+例外処理やイテレータなどの機構によって，より分かりやすいプログラミングが出来ます．
+
+## Rubyの特長
+
+*   シンプルな文法
+*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
+*   特殊なオブジェクト指向機能(Mixin，特異メソッドなど)
+*   演算子オーバーロード
+*   例外処理機能
+*   イテレータとクロージャ
+*   ガーベージコレクタ
+*   ダイナミックローディング (アーキテクチャによる)
+*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で動くだけでなく，Windows， macOS，
+    Haikuなどの上でも動く cf.
+    https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#platform-maintainers

+
+Ruby開発者向けメーリングリストもあります．こちらではrubyのバグ，将来の仕様拡張など実装上の問題について議論されています．
+参加希望の方は [ruby-dev-request@ruby-lang.org] までruby-listと同様の方法でメールしてください．
+
+Ruby拡張モジュールについて話し合うruby-extメーリングリストと数学関係の話題について話し合うruby-mathメーリングリストと
+英語でrubyについて話し合うruby-talkメーリングリストもあります．参加方法はどれも同じです．

+[ruby-dev-request@ruby-lang.org]: mailto:ruby-dev-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe
+
+## コンパイル・インストール
+
+以下の手順で行ってください．
+
+1.  (Gitリポジトリから取得したソースをビルドする場合) `./autogen.sh` を実行して新しく `configure` を生成する
+
+2.  `configure` を実行して `Makefile` などを生成する
+
+    環境によってはデフォルトのCコンパイラ用オプションが付きます． `configure` オプションで `optflags=..`
+    `warnflags=..` 等で上書きできます．
+
+3.  (必要ならば)`include/ruby/defines.h` を編集する
+
+    多分，必要無いと思います．
+
+4.  (必要ならば)`ext/Setup` に静的にリンクする拡張モジュールを指定する
+
+    `ext/Setup` に記述したモジュールは静的にリンクされます．
+
+    ダイナミックローディングをサポートしていないアーキテクチャでは `Setup` の1行目の「`option nodynamic`」という行のコ
+    メントを外す必要があります．
+    また，このアーキテクチャで拡張モジュールを利用するためには，あらかじめ静的にリンクをしておく必要があります．
+
+5.  `make` を実行してコンパイルする
+
+6.  `make check`でテストを行う．
+
+    「`check succeeded`」と表示されれば成功です．ただしテストに成功しても完璧だと保証されている訳ではありません．
+
+7.  `make install`
+
+    以下のディレクトリを作って，そこにファイルをインストー ルします．
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    RubyのAPIバージョンが'*x.y.z*'であれば，`${MAJOR}`は
+    '*x*'で，`${MINOR}`は'*y*'，`${TEENY}`は'*z*'です．
+
+    **注意**: APIバージョンの `teeny` は，Rubyプログラムのバージョンとは異なることがあります．
+
+    `root` で作業する必要があるかもしれません．
+
+
+もし，コンパイル時にエラーが発生した場合にはエラーのログとマシン，OSの種類を含むできるだけ詳しいレポートを作者に送って下さると他の方のためにもなります．
+
+## 移植
+
+UNIXであれば `configure` がほとんどの差異を吸収してくれるはずですが，思わぬ見落としがあった場合(ある事が多い)，作者にその
+ことを報告すれば，解決できる可能性があります．
+
+アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
+のアーキテクチャが`setjmp()`または`getcontext()`によって全てのレジスタを `jmp_buf` や `ucontext_t`
+に格納することと， `jmp_buf` や `ucontext_t` とスタックが32bitアラインメントされていることを仮定
+しています．特に前者が成立しない場合の対応は非常に困難でしょう． 後者の解決は比較的簡単で， `gc.c` でスタックをマークしている
+部分にアラインメントのバイト数だけずらしてマークするコードを追加するだけで済みます．`defined(__mc68000__)`で括られてい
+る部分を参考にしてください．
+
+レジスタウィンドウを持つCPUでは，レジスタウィンドウをスタックにフラッシュするアセンブラコードを追加する必要があるかもしれません．

+# What is Ruby?
+
+Ruby is an interpreted object-oriented programming language often
+used for web development. It also offers many scripting features
+to process plain text and serialized files, or manage system tasks.
+It is simple, straightforward, and extensible.
+
+## Features of Ruby
+
+* Simple Syntax
+* **Normal** Object-oriented Features (e.g. class, method calls)
+* **Advanced** Object-oriented Features (e.g. mix-in, singleton-method)
+* Operator Overloading
+* Exception Handling
+* Iterators and Closures
+* Garbage Collection
+* Dynamic Loading of Object Files (on some architectures)
+* Highly Portable (works on many Unix-like/POSIX compatible platforms as
+  well as Windows, macOS, etc.) cf.

+ *  An \Array is an ordered, integer-indexed collection of objects, called _elements_.
+ *  Any object (even another array) may be an array element,
+ *  and an array can contain objects of different types.
+ *
+ *  == \Array Indexes
+ *
+ *  \Array indexing starts at 0, as in C or Java.
+ *
+ *  A positive index is an offset from the first element:
+ *
+ *  - Index 0 indicates the first element.
+ *  - Index 1 indicates the second element.
+ *  - ...
+ *
+ *  A negative index is an offset, backwards, from the end of the array:
+ *
+ *  - Index -1 indicates the last element.
+ *  - Index -2 indicates the next-to-last element.
+ *  - ...
+ *
+ *  A non-negative index is <i>in range</i> if and only if it is smaller than
+ *  the size of the array.  For a 3-element array:
+ *
+ *  - Indexes 0 through 2 are in range.
+ *  - Index 3 is out of range.
+ *
+ *  A negative index is <i>in range</i> if and only if its absolute value is
+ *  not larger than the size of the array.  For a 3-element array:
+ *
+ *  - Indexes -1 through -3 are in range.
+ *  - Index -4 is out of range.
+ *
+ *  Although the effective index into an array is always an integer,
+ *  some methods (both within and outside of class \Array)
+ *  accept one or more non-integer arguments that are
+ *  {integer-convertible objects}[rdoc-ref:implicit_conversion.rdoc@Integer-Convertible+Objects].
+ *
+ *
+ *  == Creating Arrays
+ *
+ *  You can create an \Array object explicitly with:
+ *
+ *  - An {array literal}[rdoc-ref:literals.rdoc@Array+Literals]:
+ *
+ *      [1, 'one', :one, [2, 'two', :two]]
+ *
+ *  - A {%w or %W: string-array Literal}[rdoc-ref:literals.rdoc@25w+and+-25W-3A+String-Array+Literals]:
+ *
+ *      %w[foo bar baz] # => ["foo", "bar", "baz"]
+ *      %w[1 % *]       # => ["1", "%", "*"]
+ *
+ *  - A {%i pr %I: symbol-array Literal}[rdoc-ref:literals.rdoc@25i+and+-25I-3A+Symbol-Array+Literals]:
+ *
+ *      %i[foo bar baz] # => [:foo, :bar, :baz]
+ *      %i[1 % *]       # => [:"1", :%, :*]
+ *
+ *  - \Method Kernel#Array:
+ *
+ *      Array(["a", "b"])             # => ["a", "b"]
+ *      Array(1..5)                   # => [1, 2, 3, 4, 5]
+ *      Array(key: :value)            # => [[:key, :value]]
+ *      Array(nil)                    # => []
+ *      Array(1)                      # => [1]
+ *      Array({:a => "a", :b => "b"}) # => [[:a, "a"], [:b, "b"]]
+ *
+ *  - \Method Array.new:
+ *
+ *      Array.new               # => []
+ *      Array.new(3)            # => [nil, nil, nil]
+ *      Array.new(4) {Hash.new} # => [{}, {}, {}, {}]
+ *      Array.new(3, true)      # => [true, true, true]
+ *
+ *    Note that the last example above populates the array
+ *    with references to the same object.
+ *    This is recommended only in cases where that object is a natively immutable object
+ *    such as a symbol, a numeric, +nil+, +true+, or +false+.
+ *
+ *    Another way to create an array with various objects, using a block;
+ *    this usage is safe for mutable objects such as hashes, strings or
+ *    other arrays:
+ *
+ *      Array.new(4) {|i| i.to_s } # => ["0", "1", "2", "3"]
+ *
+ *    Here is a way to create a multi-dimensional array:
+ *
+ *      Array.new(3) {Array.new(3)}
+ *      # => [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ *  A number of Ruby methods, both in the core and in the standard library,
+ *  provide instance method +to_a+, which converts an object to an array.

+ *
+ *  == Example Usage
+ *
+ *  In addition to the methods it mixes in through the Enumerable module, the
+ *  \Array class has proprietary methods for accessing, searching and otherwise
+ *  manipulating arrays.
+ *
+ *  Some of the more common ones are illustrated below.
+ *
+ *  == Accessing Elements
+ *
+ *  Elements in an array can be retrieved using the Array#[] method.  It can
+ *  take a single integer argument (a numeric index), a pair of arguments
+ *  (start and length) or a range. Negative indices start counting from the end,
+ *  with -1 being the last element.
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr[2]    #=> 3
+ *     arr[100]  #=> nil
+ *     arr[-3]   #=> 4
+ *     arr[2, 3] #=> [3, 4, 5]
+ *     arr[1..4] #=> [2, 3, 4, 5]
+ *     arr[1..-3] #=> [2, 3, 4]
+ *
+ *  Another way to access a particular array element is by using the #at method
+ *
+ *     arr.at(0) #=> 1
+ *
+ *  The #slice method works in an identical manner to Array#[].
+ *
+ *  To raise an error for indices outside of the array bounds or else to
+ *  provide a default value when that happens, you can use #fetch.
+ *
+ *     arr = ['a', 'b', 'c', 'd', 'e', 'f']
+ *     arr.fetch(100) #=> IndexError: index 100 outside of array bounds: -6...6
+ *     arr.fetch(100, "oops") #=> "oops"
+ *
+ *  The special methods #first and #last will return the first and last
+ *  elements of an array, respectively.
+ *
+ *     arr.first #=> 1
+ *     arr.last  #=> 6
+ *
+ *  To return the first +n+ elements of an array, use #take
+ *
+ *     arr.take(3) #=> [1, 2, 3]
+ *
+ *  #drop does the opposite of #take, by returning the elements after +n+
+ *  elements have been dropped:
+ *
+ *     arr.drop(3) #=> [4, 5, 6]
+ *
+ *  == Obtaining Information about an \Array
+ *
+ *  Arrays keep track of their own length at all times.  To query an array
+ *  about the number of elements it contains, use #length, #count or #size.
+ *
+ *    browsers = ['Chrome', 'Firefox', 'Safari', 'Opera', 'IE']
+ *    browsers.length #=> 5
+ *    browsers.count #=> 5
+ *
+ *  To check whether an array contains any elements at all
+ *
+ *    browsers.empty? #=> false
+ *
+ *  To check whether a particular item is included in the array
+ *
+ *    browsers.include?('Konqueror') #=> false
+ *
+ *  == Adding Items to Arrays
+ *
+ *  Items can be added to the end of an array by using either #push or #<<
+ *
+ *    arr = [1, 2, 3, 4]
+ *    arr.push(5) #=> [1, 2, 3, 4, 5]
+ *    arr << 6    #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  #unshift will add a new item to the beginning of an array.
+ *
+ *     arr.unshift(0) #=> [0, 1, 2, 3, 4, 5, 6]
+ *
+ *  With #insert you can add a new element to an array at any position.
+ *
+ *     arr.insert(3, 'apple')  #=> [0, 1, 2, 'apple', 3, 4, 5, 6]
+ *
+ *  Using the #insert method, you can also insert multiple values at once:
+ *
+ *     arr.insert(3, 'orange', 'pear', 'grapefruit')
+ *     #=> [0, 1, 2, "orange", "pear", "grapefruit", "apple", 3, 4, 5, 6]
+ *
+ *  == Removing Items from an \Array
+ *
+ *  The method #pop removes the last element in an array and returns it:
+ *
+ *     arr =  [1, 2, 3, 4, 5, 6]
+ *     arr.pop #=> 6
+ *     arr #=> [1, 2, 3, 4, 5]
+ *
+ *  To retrieve and at the same time remove the first item, use #shift:
+ *
+ *     arr.shift #=> 1
+ *     arr #=> [2, 3, 4, 5]
+ *
+ *  To delete an element at a particular index:
+ *
+ *     arr.delete_at(2) #=> 4
+ *     arr #=> [2, 3, 5]
+ *
+ *  To delete a particular element anywhere in an array, use #delete:
+ *
+ *     arr = [1, 2, 2, 3]
+ *     arr.delete(2) #=> 2
+ *     arr #=> [1,3]
+ *
+ *  A useful method if you need to remove +nil+ values from an array is
+ *  #compact:
+ *
+ *     arr = ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact  #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact! #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, 'bar', 7, 'baz']
+ *
+ *  Another common need is to remove duplicate elements from an array.
+ *
+ *  It has the non-destructive #uniq, and destructive method #uniq!
+ *
+ *     arr = [2, 5, 6, 556, 6, 6, 8, 9, 0, 123, 556]
+ *     arr.uniq #=> [2, 5, 6, 556, 8, 9, 0, 123]
+ *
+ *  == Iterating over Arrays
+ *
+ *  Like all classes that include the Enumerable module, \Array has an each
+ *  method, which defines what elements should be iterated over and how.  In
+ *  case of Array's #each, all elements in the \Array instance are yielded to
+ *  the supplied block in sequence.
+ *
+ *  Note that this operation leaves the array unchanged.
+ *
+ *     arr = [1, 2, 3, 4, 5]
+ *     arr.each {|a| print a -= 10, " "}
+ *     # prints: -9 -8 -7 -6 -5
+ *     #=> [1, 2, 3, 4, 5]
+ *
+ *  Another sometimes useful iterator is #reverse_each which will iterate over
+ *  the elements in the array in reverse order.
+ *
+ *     words = %w[first second third fourth fifth sixth]
+ *     str = ""
+ *     words.reverse_each {|word| str += "#{word} "}
+ *     p str #=> "sixth fifth fourth third second first "
+ *
+ *  The #map method can be used to create a new array based on the original
+ *  array, but with the values modified by the supplied block:
+ *
+ *     arr.map {|a| 2*a}     #=> [2, 4, 6, 8, 10]
+ *     arr                   #=> [1, 2, 3, 4, 5]
+ *     arr.map! {|a| a**2}   #=> [1, 4, 9, 16, 25]
+ *     arr                   #=> [1, 4, 9, 16, 25]
+ *
+ *
+ *  == Selecting Items from an \Array
+ *
+ *  Elements can be selected from an array according to criteria defined in a
+ *  block.  The selection can happen in a destructive or a non-destructive
+ *  manner.  While the destructive operations will modify the array they were
+ *  called on, the non-destructive methods usually return a new array with the
+ *  selected elements, but leave the original array unchanged.
+ *
+ *  === Non-destructive Selection
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.select {|a| a > 3}       #=> [4, 5, 6]
+ *     arr.reject {|a| a < 3}       #=> [3, 4, 5, 6]
+ *     arr.drop_while {|a| a < 4}   #=> [4, 5, 6]
+ *     arr                          #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  === Destructive Selection
+ *
+ *  #select! and #reject! are the corresponding destructive methods to #select
+ *  and #reject
+ *
+ *  Similar to #select vs. #reject, #delete_if and #keep_if have the exact
+ *  opposite result when supplied with the same block:
+ *
+ *     arr.delete_if {|a| a < 4}   #=> [4, 5, 6]
+ *     arr                         #=> [4, 5, 6]
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.keep_if {|a| a < 4}   #=> [1, 2, 3]
+ *     arr                       #=> [1, 2, 3]
+ *
+ *  == What's Here
+ *
+ *  First, what's elsewhere. \Class \Array:
+ *
+ *  - Inherits from {class Object}[rdoc-ref:Object@What-27s+Here].

+# AbstractSyntaxTree provides methods to parse Ruby code into
+# abstract syntax trees. The nodes in the tree
+# are instances of RubyVM::AbstractSyntaxTree::Node.
+#
+# This module is MRI specific as it exposes implementation details
+# of the MRI abstract syntax tree.
+#
+# This module is experimental and its API is not stable, therefore it might
+# change without notice. As examples, the order of children nodes is not
+# guaranteed, the number of children nodes might change, there is no way to
+# access children nodes by name, etc.
+#
+# If you are looking for a stable API or an API working under multiple Ruby
+# implementations, consider using the _parser_ gem or Ripper. If you would
+# like to make RubyVM::AbstractSyntaxTree stable, please join the discussion
+# at https://bugs.ruby-lang.org/issues/14844.

-= How to build ruby using Borland C++
-
-== Requirement
-
-(1) Borland C++ 5.0 or later.
-
-(2) Please set environment variable (({PATH}))
-    to run required commands properly from the command line.
-
-    Note: building ruby requires following commands.
-     * make
-     * bcc32
-     * tlib
-     * ilink32
-
-(3) If you want to build from CVS source, following commands are required.
-     * bison ((<URL:http://gnuwin32.sourceforge.net/packages/bison.htm>))
-     * sed   ((<URL:http://gnuwin32.sourceforge.net/packages/sed.htm>))
-
-(4) We strongly recommend to build ruby on C++Builder, to link following files.
-     * usebormm.lib
-     * memmgr.lib
-
-    RTL's internal memory manager cannot handle large memory block properly,
-    so we should use borlndmm.dll instead.
-     10000.times { "" << "." * 529671; GC.start } # crash
-
-== How to compile and install
-
-(1) Execute bcc32\configure.bat on your build directory.
-     ex. c:\src\ruby> bcc32\configure.bat
-    You can specify the target platform as an argument.
-    For example, run `((%configure i686-bccwin32%))'
-    You can also specify the install directory.
-    For example, run `((%configure --prefix=<install_directory>%))'
-    Default of the install directory is /usr .
-     
-(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
-    if you want to change the name of the executable files. 
-    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
-    executable without console window if also you want.
-
-(3) Run `((%make%))'
-
-(4) Run `((%make test%))'
-
-(5) Run `((%make install%))'
-
-    This command will create following directories and install files onto them.
-      * <install_directory>\bin
-      * <install_directory>\lib
-      * <install_directory>\lib\ruby
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\lib\ruby\site_ruby
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\man\man1
-    If Ruby's version is `x.y.z', the ((|<MAJOR>|)) is `x' and the ((|<MINOR>|)) is `y'.
-    The default ((|<PLATFORM>|)) is `(({i386-bccwin32}))'.
-
-(6) Requires dynamic RTL (cc3250.dll on C++Builder5) and borlndmm.dll (If built with
-    usebormm.lib) to use installed binary. These files are ordinary in bcc32's bin
-    directory.
-
-== Icons
-
-Any icon files(*.ico) in the build directory, directories specified with
-((|icondirs|)) make variable and (({win32})) directory under the ruby
-source directory will be included in DLL or executable files, according
-to their base names.
-    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
-    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
-    the others                             --> $(RUBY_SO_NAME).dll
-
-Although no icons are distributed with the ruby source or in the official 
-site, you can use anything you like. For example, followings are written 
-in Japanese, but you can download at least.
-
-* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
-  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
-* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
-  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
-
-== Build examples
-
-* Build on the ruby source directory.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-
-    C:
-    cd \ruby
-    bcc32\configure --prefix=/usr/local
-    make
-    make test
-    make install
-
-* Build on the relative directory from the ruby source directory and CPU type 
-  i386.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby\bccwin32
-    install directory:      C:\usr\local
-    CPU                     i386
-    
-    C:
-    cd \ruby
-    mkdir bccwin32
-    cd bccwin32
-    ..\bcc32\configure --prefix=/usr/local
-    make
-    make test
-    make install
-
-* Build on the different drive.
-
-  ex.)
-    ruby source directory:  C:\src\ruby
-    build directory:        D:\build\ruby
-    install directory:      C:\usr\local
-
-    D:
-    cd D:\build\ruby
-    C:\src\ruby\bcc32\configure --prefix=C:/usr/local
-    make
-    make test
-    make install
-
-== Bugs
-
-You can ((*NOT*)) use a path name contains any white space characters as
-the ruby source directory, this restriction comes from the behavior of
-(({!INCLUDE})) directives of (({MAKE})).
-((- you may call it a bug. -))
-

+# ruby/benchmark
+
+This directory has benchmark definitions to be run with
+[benchmark\_driver.gem](https://github.com/benchmark-driver/benchmark-driver).
+
+## Normal usage
+
+Execute `gem install benchmark_driver` and run a command like:
+
+```bash
+# Run a benchmark script with the ruby in the $PATH
+benchmark-driver benchmark/app_fib.rb
+
+# Run benchmark scripts with multiple Ruby executables or options
+benchmark-driver benchmark/*.rb -e /path/to/ruby -e '/path/to/ruby --jit'
+
+# Or compare Ruby versions managed by rbenv
+benchmark-driver benchmark/*.rb --rbenv '2.5.1;2.6.0-preview2 --jit'
+
+# You can collect many metrics in many ways
+benchmark-driver benchmark/*.rb --runner memory --output markdown
+
+# Some are defined with YAML for complex setup or accurate measurement
+benchmark-driver benchmark/*.yml
+```
+
+See also:
+
+```console
+Usage: benchmark-driver [options] RUBY|YAML...
+    -r, --runner TYPE                Specify runner type: ips, time, memory, once, block (default: ips)
+    -o, --output TYPE                Specify output type: compare, simple, markdown, record, all (default: compare)
+    -e, --executables EXECS          Ruby executables (e1::path1 arg1; e2::path2 arg2;...)
+        --rbenv VERSIONS             Ruby executables in rbenv (x.x.x arg1;y.y.y arg2;...)
+        --repeat-count NUM           Try benchmark NUM times and use the fastest result or the worst memory usage
+        --repeat-result TYPE         Yield "best", "average" or "worst" result with --repeat-count (default: best)
+        --alternate                  Alternate executables instead of running the same executable in a row with --repeat-count
+        --bundler                    Install and use gems specified in Gemfile
+        --filter REGEXP              Filter out benchmarks with given regexp
+        --run-duration SECONDS       Warmup estimates loop_count to run for this duration (default: 3)
+        --timeout SECONDS            Timeout ruby command execution with timeout(1)
+    -v, --verbose                    Verbose mode. Multiple -v options increase visilibity (max: 2)
+```
+
+## make benchmark
+
+Using `make benchmark`, `make update-benchmark-driver` automatically downloads
+the supported version of benchmark\_driver, and it runs benchmarks with the downloaded
+benchmark\_driver.
+
+```bash
+# Run all benchmarks with the ruby in the $PATH and the built ruby
+make benchmark
+
+# Or compare with specific ruby binary
+make benchmark COMPARE_RUBY="/path/to/ruby --jit"
+
+# Run vm benchmarks
+make benchmark ITEM=vm
+
+# Run some limited benchmarks in ITEM-matched files
+make benchmark ITEM=vm OPTS=--filter=block
+
+# You can specify the benchmark by an exact filename instead of using the default argument:
+# ARGS = $$(find $(srcdir)/benchmark -maxdepth 1 -name '*$(ITEM)*.yml' -o -name '*$(ITEM)*.rb')
+make benchmark ARGS=benchmark/erb_render.yml
+
+# You can specify any option via $OPTS
+make benchmark OPTS="--help"
+
+# With `make benchmark`, some special runner plugins are available:
+#   -r peak, -r size, -r total, -r utime, -r stime, -r cutime, -r cstime
+make benchmark ITEM=vm_bigarray OPTS="-r peak"

+  Hello there, Izchak Miller was my father.  When I was younger I spent 
+  many a night, hunched over the keyboard with a cup of tea, playing 
+  nethack with him and my brother.  my dad was a philosopher with a strong 
+  weakness for fantasy/sci fi.  I remember when he started to get involved 
+  with the Nethack team- my brother's Dungeons and Dragons monster book 
+  found a regular place beside my dad's desk. it's nice to see him living 
+  on in the game he loved so much :-).

-## Transitional Hack ####
-#
-#  RDoc was initially distributed independently, and installed
-#  itself into <prefix>/lib/ruby/site_ruby/<ver>/rdoc...
-#
-#  Now that RDoc is part of the distribution, it's installed into
-#  <prefix>/lib/ruby/<ver>, which unfortunately appears later in the
-#  search path. This means that if you have previously installed RDoc,
-#  and then install from ruby-lang, you'll pick up the old one by
-#  default. This hack checks for the condition, and readjusts the
-#  search path if necessary.

-# == Installing Documentation
-#
-# 'ri' uses a database of documentation built by the RDoc utility.
-# 
-# So, how do you install this documentation on your system?
-# It depends on how you installed Ruby.
-#
-# <em>If you installed Ruby from source files</em> (that is, if it some point
-# you typed 'make' during the process :), you can install the RDoc
-# documentation yourself. Just go back to the place where you have 
-# your Ruby source and type
-#
-#    make install-doc
-#
-# You'll probably need to do this as a superuser, as the documentation
-# is installed in the Ruby target tree (normally somewhere under 
-# <tt>/usr/local</tt>.
-#
-# <em>If you installed Ruby from a binary distribution</em> (perhaps
-# using a one-click installer, or using some other packaging system),
-# then the team that produced the package probably forgot to package
-# the documentation as well. Contact them, and see if they can add
-# it to the next release.

+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:
+
+    the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
+    moral rights retained by the original author(s) and/or performer(s);
+    publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
+    rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
+    rights protecting the extraction, dissemination, use and reuse of data in a Work;
+    database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
+    other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+    No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
+    Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
+    Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.
+    Affirmer understands and acknowledges that Creative Commons is not a party to this document and has no duty or obligation with respect to this CC0 or use of the Work.

+     * - It contains key-value pairs.  So we need to take every two elements.
+     *   We can assume that the length is always even.
+     *
+     * - Merging is done by a method call (id_core_hash_merge_ptr).
+     *   Sometimes we need to insert the receiver, so "anchor" is needed.
+     *   In addition, a method call is much slower than concatarray.
+     *   So it pays only when the subsequence is really long.
+     *   (min_tmp_hash_len must be much larger than min_tmp_ary_len.)
+     *
+     * - We need to handle keyword splat: **kw.
+     *   For **kw, the key part (node->nd_head) is NULL, and the value part
+     *   (node->nd_next->nd_head) is "kw".
+     *   The code is a bit difficult to avoid hash allocation for **{}.

+/* Multiple Assignment Handling
+ *
+ * In order to handle evaluation of multiple assignment such that the left hand side
+ * is evaluated before the right hand side, we need to process the left hand side
+ * and see if there are any attributes that need to be assigned, or constants set
+ * on explicit objects.  If so, we add instructions to evaluate the receiver of
+ * any assigned attributes or constants before we process the right hand side.
+ *
+ * For a multiple assignment such as:
+ *
+ *   l1.m1, l2[0] = r3, r4
+ *
+ * We start off evaluating l1 and l2, then we evaluate r3 and r4, then we
+ * assign the result of r3 to l1.m1, and then the result of r4 to l2.m2.
+ * On the VM stack, this looks like:
+ *
+ *     self                               # putself
+ *     l1                                 # send
+ *     l1, self                           # putself
+ *     l1, l2                             # send
+ *     l1, l2, 0                          # putobject 0
+ *     l1, l2, 0, [r3, r4]                # after evaluation of RHS
+ *     l1, l2, 0, [r3, r4], r4, r3        # expandarray
+ *     l1, l2, 0, [r3, r4], r4, r3, l1    # topn 5
+ *     l1, l2, 0, [r3, r4], r4, l1, r3    # swap
+ *     l1, l2, 0, [r3, r4], r4, m1=       # send
+ *     l1, l2, 0, [r3, r4], r4            # pop
+ *     l1, l2, 0, [r3, r4], r4, l2        # topn 3
+ *     l1, l2, 0, [r3, r4], r4, l2, 0     # topn 3
+ *     l1, l2, 0, [r3, r4], r4, l2, 0, r4 # topn 2
+ *     l1, l2, 0, [r3, r4], r4, []=       # send

+ *     [r3, r4]                           # pop
+ *
+ * This is made more complex when you have to handle splats, post args,
+ * and arbitrary levels of nesting.  You need to keep track of the total
+ * number of attributes to set, and for each attribute, how many entries
+ * are on the stack before the final attribute, in order to correctly
+ * calculate the topn value to use to get the receiver of the attribute
+ * setter method.

+ *     lhs_attr1, lhs_attr2, ..., rhs_array, ..., rhs_arg2, rhs_arg1
+ *
+ * For multiple assignment with splats, while processing the part before
+ * the splat (splat+post here is an array of the splat and the post arguments):
+ *
+ *     lhs_attr1, lhs_attr2, ..., rhs_array, splat+post, ..., rhs_arg2, rhs_arg1
+ *
+ * When processing the splat and post arguments:
+ *
+ *     lhs_attr1, lhs_attr2, ..., rhs_array, ..., post_arg2, post_arg1, splat
+ *
+ * When processing nested multiple assignment, existing values on the stack
+ * are kept.  So for:
+ *
+ *     (l1.m1, l2.m2), l3.m3, l4* = [r1, r2], r3, r4
+ *
+ * The stack layout would be the following before processing the nested
+ * multiple assignment:
+ *
+ *     l1, l2, [[r1, r2], r3, r4], [r4], r3, [r1, r2]
+ *
+ * In order to handle this correctly, we need to keep track of the nesting
+ * level for each attribute assignment, as well as the attribute number
+ * (left hand side attributes are processed left to right) and number of
+ * arguments to pass to the setter method. struct masgn_lhs_node tracks
+ * this information.
+ *
+ * We also need to track information for the entire multiple assignment, such
+ * as the total number of arguments, and the current nesting level, to
+ * handle both nested multiple assignment as well as cases where the
+ * rhs is not needed.  We also need to keep track of all attribute
+ * assignments in this, which we do using a linked listed. struct masgn_state
+ * tracks this information.

+/*
+ *  Document-class: Fiber
+ *
+ *  Fibers are primitives for implementing light weight cooperative
+ *  concurrency in Ruby. Basically they are a means of creating code blocks
+ *  that can be paused and resumed, much like threads. The main difference
+ *  is that they are never preempted and that the scheduling must be done by
+ *  the programmer and not the VM.
+ *
+ *  As opposed to other stackless light weight concurrency models, each fiber
+ *  comes with a stack.  This enables the fiber to be paused from deeply
+ *  nested function calls within the fiber block.  See the ruby(1)
+ *  manpage to configure the size of the fiber stack(s).
+ *
+ *  When a fiber is created it will not run automatically. Rather it must
+ *  be explicitly asked to run using the Fiber#resume method.
+ *  The code running inside the fiber can give up control by calling
+ *  Fiber.yield in which case it yields control back to caller (the
+ *  caller of the Fiber#resume).
+ *
+ *  Upon yielding or termination the Fiber returns the value of the last
+ *  executed expression
+ *
+ *  For instance:
+ *
+ *    fiber = Fiber.new do
+ *      Fiber.yield 1
+ *      2
+ *    end
+ *
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *
+ *  <em>produces</em>
+ *
+ *    1
+ *    2
+ *    FiberError: dead fiber called
+ *
+ *  The Fiber#resume method accepts an arbitrary number of parameters,
+ *  if it is the first call to #resume then they will be passed as
+ *  block arguments. Otherwise they will be the return value of the
+ *  call to Fiber.yield
+ *
+ *  Example:
+ *
+ *    fiber = Fiber.new do |first|
+ *      second = Fiber.yield first + 2
+ *    end
+ *
+ *    puts fiber.resume 10
+ *    puts fiber.resume 1_000_000
+ *    puts fiber.resume "The fiber will be dead before I can cause trouble"
+ *
+ *  <em>produces</em>
+ *
+ *    12
+ *    1000000
+ *    FiberError: dead fiber called
+ *
+ *  == Non-blocking Fibers
+ *
+ *  The concept of <em>non-blocking fiber</em> was introduced in Ruby 3.0.
+ *  A non-blocking fiber, when reaching a operation that would normally block
+ *  the fiber (like <code>sleep</code>, or wait for another process or I/O)
+ *  will yield control to other fibers and allow the <em>scheduler</em> to
+ *  handle blocking and waking up (resuming) this fiber when it can proceed.
+ *
+ *  For a Fiber to behave as non-blocking, it need to be created in Fiber.new with
+ *  <tt>blocking: false</tt> (which is the default), and Fiber.scheduler
+ *  should be set with Fiber.set_scheduler. If Fiber.scheduler is not set in
+ *  the current thread, blocking and non-blocking fibers' behavior is identical.
+ *
+ *  Ruby doesn't provide a scheduler class: it is expected to be implemented by
+ *  the user and correspond to Fiber::Scheduler.
+ *
+ *  There is also Fiber.schedule method, which is expected to immediately perform
+ *  the given block in a non-blocking manner. Its actual implementation is up to
+ *  the scheduler.

+ *  call-seq:
+ *     fiber.transfer(args, ...) -> obj
+ *
+ *  Transfer control to another fiber, resuming it from where it last
+ *  stopped or starting it if it was not resumed before. The calling
+ *  fiber will be suspended much like in a call to
+ *  Fiber.yield.
+ *
+ *  The fiber which receives the transfer call treats it much like
+ *  a resume call. Arguments passed to transfer are treated like those
+ *  passed to resume.
+ *
+ *  The two style of control passing to and from fiber (one is #resume and
+ *  Fiber::yield, another is #transfer to and from fiber) can't be freely
+ *  mixed.
+ *
+ *  * If the Fiber's lifecycle had started with transfer, it will never
+ *    be able to yield or be resumed control passing, only
+ *    finish or transfer back. (It still can resume other fibers that
+ *    are allowed to be resumed.)
+ *  * If the Fiber's lifecycle had started with resume, it can yield
+ *    or transfer to another Fiber, but can receive control back only
+ *    the way compatible with the way it was given away: if it had
+ *    transferred, it only can be transferred back, and if it had
+ *    yielded, it only can be resumed back. After that, it again can
+ *    transfer or yield.
+ *
+ *  If those rules are broken FiberError is raised.
+ *
+ *  For an individual Fiber design, yield/resume is easier to use
+ *  (the Fiber just gives away control, it doesn't need to think
+ *  about who the control is given to), while transfer is more flexible
+ *  for complex cases, allowing to build arbitrary graphs of Fibers
+ *  dependent on each other.
+ *
+ *
+ *  Example:
+ *
+ *     manager = nil # For local var to be visible inside worker block
+ *
+ *     # This fiber would be started with transfer
+ *     # It can't yield, and can't be resumed
+ *     worker = Fiber.new { |work|
+ *       puts "Worker: starts"
+ *       puts "Worker: Performed #{work.inspect}, transferring back"
+ *       # Fiber.yield     # this would raise FiberError: attempt to yield on a not resumed fiber
+ *       # manager.resume  # this would raise FiberError: attempt to resume a resumed fiber (double resume)
+ *       manager.transfer(work.capitalize)
+ *     }
+ *
+ *     # This fiber would be started with resume
+ *     # It can yield or transfer, and can be transferred
+ *     # back or resumed
+ *     manager = Fiber.new {
+ *       puts "Manager: starts"
+ *       puts "Manager: transferring 'something' to worker"
+ *       result = worker.transfer('something')
+ *       puts "Manager: worker returned #{result.inspect}"
+ *       # worker.resume    # this would raise FiberError: attempt to resume a transferring fiber
+ *       Fiber.yield        # this is OK, the fiber transferred from and to, now it can yield
+ *       puts "Manager: finished"
+ *     }
+ *
+ *     puts "Starting the manager"
+ *     manager.resume
+ *     puts "Resuming the manager"

+# Objects of class Dir are directory streams representing
+# directories in the underlying file system. They provide a variety
+# of ways to list directories and their contents. See also File.
+#
+# The directory used in these examples contains the two regular files
+# (<code>config.h</code> and <code>main.rb</code>), the parent
+# directory (<code>..</code>), and the directory itself
+# (<code>.</code>).
+#
+# == What's Here
+#
+# First, what's elsewhere. \Class \Dir:
+#
+# - Inherits from {class Object}[rdoc-ref:Object@What-27s+Here].
+# - Includes {module Enumerable}[rdoc-ref:Enumerable@What-27s+Here],
+#   which provides dozens of additional methods.
+#
+# Here, class \Dir provides methods that are useful for:
+#
+# - {Reading}[rdoc-ref:Dir@Reading]
+# - {Setting}[rdoc-ref:Dir@Setting]
+# - {Querying}[rdoc-ref:Dir@Querying]
+# - {Iterating}[rdoc-ref:Dir@Iterating]
+# - {Other}[rdoc-ref:Dir@Other]
+#
+# === Reading
+#
+# - #close: Closes the directory stream for +self+.
+# - #pos=: Sets the position in the directory stream for +self+.
+# - #read: Reads and returns the next entry in the directory stream for +self+.
+# - #rewind: Sets the position in the directory stream for +self+ to the first entry.
+# - #seek: Sets the position in the directory stream for +self+
+#   the entry at the given offset.
+#
+# === Setting
+#
+# - ::chdir: Changes the working directory of the current process
+#   to the given directory.
+# - ::chroot: Changes the file-system root for the current process
+#   to the given directory.
+#
+# === Querying
+#
+# - ::[]: Same as ::glob without the ability to pass flags.
+# - ::children: Returns an array of names of the children
+#   (both files and directories) of the given directory,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - ::empty?: Returns whether the given path is an empty directory.
+# - ::entries: Returns an array of names of the children
+#   (both files and directories) of the given directory,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - ::exist?: Returns whether the given path is a directory.
+# - ::getwd (aliased as #pwd): Returns the path to the current working directory.
+# - ::glob: Returns an array of file paths matching the given pattern and flags.
+# - ::home: Returns the home directory path for a given user or the current user.
+# - #children: Returns an array of names of the children
+#   (both files and directories) of +self+,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - #fileno: Returns the integer file descriptor for +self+.
+# - #path (aliased as #to_path): Returns the path used to create +self+.
+# - #tell (aliased as #pos): Returns the integer position
+#   in the directory stream for +self+.
+#
+# === Iterating
+#
+# - ::each_child: Calls the given block with each entry in the given directory,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - ::foreach: Calls the given block with each entry in the given directory,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - #each: Calls the given block with each entry in +self+,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - #each_child: Calls the given block with each entry in +self+,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+#
+# === Other
+#
+# - ::mkdir: Creates a directory at the given path, with optional permissions.
+# - ::new: Returns a new \Dir for the given path, with optional encoding.
+# - ::open: Same as ::new, but if a block is given, yields the \Dir to the block,
+#   closing it upon block exit.
+# - ::unlink (aliased as ::delete and ::rmdir): Removes the given directory.
+# - #inspect: Returns a string description of +self+.

+  #   two literals may be specified.
+  #
+  # <code>\\</code>::
+  #   Escapes the next metacharacter.
+  #
+  #   Note that this means you cannot use backslash on windows as part of a
+  #   glob, i.e.  <code>Dir["c:\\foo*"]</code> will not work, use
+  #   <code>Dir["c:/foo*"]</code> instead.
+  #

-* How to compile and install on djgpp
-
-This is what you need to do to compile and install Ruby:
-
-  1. Run configure.bat, which will generate config.h and Makefile
-     (GNU sed required).
-     Message like this is normal:
-       sed.exe: can't read 123456789: No such file or directory (ENOENT)
-
-  2. Edit defines.h if you need.  Probably this step will not need.
-
-  3. Remove comment mark(#) before the module names from ext/Setup.dj (or
-     add module names if not present).
-
-  4. Run make.
-
-  5. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  6. Run 'make install'

+Fri Oct 14 13:22:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* version 0.52: ……なんてこったい.
+
+	* eval.c(rb_call): returnの処理が間違っていたので, マシンによって
+	  はreturnで関数を終了するだけでなくtoplevelまでつき抜けていた.
+
+	* object.c: Builtinクラスを新設. 組み込み関数をKernelから移した.
+	  nilが組み込み関数を理解するとトラブルの元である.
+
+	* dbm.c: Dictと同様にeachが[key,value]を返すように.
+
+	* version 0.51
+
+Thu Oct 13 12:13:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(SETUP_ARGS): 付加演算子が配列でない時には配列に変換する.
+
+	* parse.y: 括弧なしのメソッド呼び出しでも`*'による付加引数が使える
+	  ようにした. ただし, 通常引数が一つもない場合は乗算演算子と区別が
+	  つかないので, 必ず括弧が必要.
+
+Wed Oct 12 10:09:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(rb_call): キャッシュの計算をinline化. キャッシュミスがあ
+	  れば関数呼び出しでメソッドを検索する. methods.cはなくなった.
+
+	* eval.c(rb_eval): ローカル変数用の領域をalloca()するように変更.
+	  サイズの変更が必要になれば改めてmalloc()するように.
+
+	* parse.y: error recoveryの際にlex_stateを更新しておくように.
+
+Tue Oct 11 17:10:46 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* socket.c(for_fd): ファイル記述子(Fixnum)からソケットインスタンス
+	  を得るメソッド. たとえばinetdから起動されたサーバで標準入出力に
+	  ソケット操作を行なうために使う. つまりSocket.for_fd($stdin)で標
+	  準入力に対応するソケットオブジェクトが得られる.
+
+	* io.c(to_i): IOクラスのインスタンスを整数に変換するとそのファイル
+	  記述子を返すように.
+
+	* numeric.c(num2int): to_iメソッドを使ってできる限り整数に変換する.
+	  以前はnum2fixだけが全てのオブジェクトに対してto_iメソッドを適用
+	  していた.
+
+	* sprintf.c(Fsprintf): 整数表示の際, オブジェクトをできる限り整数
+	  に変換するように(to_iメソッドを使う).
+
+Fri Oct  7 14:06:32 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Fcaller): 必要性がよく分からないのでドキュメントから削除.
+	  将来デバッガを作る時に復活させよう.
+
+	* eval.c(rb_call): Cで記述されたメソッド呼び出しでは環境をスタック
+	  にセーブしないことによって高速化.
+
+Wed Oct  5 15:00:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.h: 一時env.hに移動してたQselfの定義を復活. ただし今回は関数
+	  として実現(env.hでは変数として再定義してある).
+
+	* ruby.h: TRUEでsyntax errorにならないよう#undefを追加.
+
+	* eval.c(rb_eval): thread化に挑戦したが, 失敗(速くならなかった).
+	  が, Scopingなどの無駄なコードの削除とメソッド呼び出しの引数セッ
+	  トのinline化で若干の高速化を実現した. 副作用として, argc, argv形
+	  式の関数呼び出しの仕様が変化した(argvにselfを含まなくなった).
+
+	* eval.c(rb_call): メソッド呼び出しの高速化.
+
+Tue Oct  4 11:40:53 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby-mode.el: 修飾子に対応した.
+
+	* parse.y: 多重代入にrestをつけた. この機能を使えばoptional引数の
+	  解析が簡単にできる(はず).
+
+	* pack.c(unpack): uuencode形式のdecodeの際に文字列の長さが間違って
+	  いた.
+
+Mon Oct  3 15:58:41 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* file.c(type): ファイルタイプを文字列で返すメソッド.
+
+Fri Sep 30 11:36:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* object.c: デフォルトの真の値である%TRUEの値を1(Fixnum)からtに変
+	  更した. to_sで文字列に変換した時にも`t'と表示される. 更に踏み込
+	  んで`t'を予約語にしてlispのようにしようかとも思ったが, そこまで
+	  は決心できなかった. 一文字のローカル変数はかなり使いそうな気がす
+	  るので….
+
+	* array.c,dict.c: equalを再定義しているクラスで, hashを正しく定義
+	  した.
+
+Wed Sep 28 23:30:28 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(Ffail): 今までfailはカーネルクラスのメソッドであったが,
+	  構文に組み込んだ. この変更によって, 1)`fail'は予約語となり, ロー
+	  カル変数に用いることができなくなった. 2)`fail'単体で例外を発生す
+	  るようになった. 3)failはメソッドではなくなったので再定義される可
+	  能性がなくなった.
+
+	* dic.c, dbm.c(indexes): Arrayのindexesと同様の機能を持つメソッド
+	  を追加.
+
+	* array.c(indexes): 引数をインデックスとする要素の配列を返す. 整数
+	  の配列を引数とする時には引数の要素をインデックスとする要素の配列
+	  を返す.
+
+Mon Sep 19 13:42:31 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* array.c(aset): 部分配列に対する代入で配列以外のオブジェクトが指
+	  定された場合に多重代入と同じルールで配列化するようにした.
+
+	* io.c(print): 引数として与えられた各オブジェクトにprint_onメッセー
+	  ジを与えるように. 実行速度は落ちるが柔軟性は増す.
+
+Fri Sep 16 14:59:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* glob.c: ワイルドカードの導入. bashに使われているGNUのglobルーチ
+	  ンを流用した.
+
+Mon Sep 12 18:36:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(value_expr): 式がnilの時に対応.
+
+	* class.c: ICLASSのclassが必ずClass/Moduleを指すように.
+
+Tue Sep  6 16:23:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* re.c:	正規表現内で「\数字」形式が指定できるように.
+
+	* parse.y:「do expr using var ... end」形式はなくなった. 寂しい気
+	  もする. *BACKWARD INCOMPATIBILITY*
+
+Mon Sep  5 10:59:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* numeric.c(next): Numericクラスにもnextを提供.
+
+	* string.c(upto): uptoを提供.
+
+	* range.c(each): nextを使ったインタフェースからuptoを使うように変
+	  更した. この方が一つのメソッドで処理をまとめで行なうことができる.
+
+Fri Sep  2 15:25:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* dict.c(each): 戻り値を[key, value]のペアに変更. 今までのeachは
+	  each_valueとして残る. *BACKWARD INCOMPATIBILITY*
+
+Thu Sep  1 10:49:04 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 成功した(特別な戻り値を持たない)システムコールは`0'を返すように.
+
+Wed Aug 31 00:26:51 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* string.c: チェックサムを得るメソッド`sum'を作った.
+
+	* class.c(include_class_new): ICLASSのclassをもとのクラスにした.
+	  gcの際に元クラスをマークする必要があるのが, フィールドを増やす余
+	  地が無いので, classフィールドを流用した. 私の見積りが間違ってい
+	  て, ICLASSのインスタンスにメッセージを送る事があれば, おかしな動
+	  作をするだろう.
+
+	* eval.c(masign): 式(a,b = nil)の値を[nil]からnilに変更した.
+
+Mon Aug 29 11:56:09 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* class.c: rb_define_mfuncを無くして, メタクラスにモジュールをイン
+	  クルードするようにした.
+
+	* error.c(yyerror): 同じ行で複数のsyntax errorをリポートしないよう
+	  にした.
+
+	* file.c: FileTestモジュールにファイルテストメソッドを分離した.
+

+
+Sat Aug 27 01:23:34 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y: if/whileなどの複合式をprimaryに移動した. これによって例
+	  えば「if cond then a else b end.message()」のような式が書けるよ
+	  うになった.
+
+Fri Aug 26 10:46:30 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* spec: 整理された文法にしたがって書き直した.
+
+	* parse.y: ここ数日で混乱していた文法を整理した. 括弧を省略したメ
+	  ソッド呼び出しができるようになったこと, modifierが付けられるよう
+	  になったこと, returnにリストが渡せるようになったことが主な変更点
+	  である.
+
+	* process周りが怪しいがとにかくSolaris 2.3で動くように.
+
+	* parse.y: 曖昧性がない場合にはメソッド呼び出しの引数の括弧を省略
+	  できるように. 省略できるメソッド呼び出しの条件は, 1)かならず1個
+	  以上の引数を必要とすること, 2)第1引数が`+', `-', `(', `[', `{',
+	  `/'など, 式の始まりに置かれた時と途中に現れた時とで解釈が違う記
+	  号で始まらないこと, である.
+
+Thu Aug 25 13:54:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(cond): 条件式の展開部にbugがあった.
+
+Wed Aug 24 00:01:15 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y: returnはコンマで区切ったリストも受け取るように. つまり,
+	  return a, b, cはreturn [a, b, c]と同じ意味になる.
+
+	* parse.y: yield以外の大域脱出制御式をexprからexpr0に移した. よっ
+	  てメソッドの引数に制御式を使えなくなる(これで困る人はいないはず).
+
+	* parse.y: `+'の定数展開の際に演算子の優先順位を忘れていた.
+
+	* eval.c: untilの戻り値はnilになった.
+
+	* parse.y: modifierとしてのif/unless/while/untilを追加.
+
+	* parse.y: 文法からendの後ろにつけるキーワードを削除. ほとんど使わ
+	  なかった上に, emacsではruby-modeがあれば対応のチェックが機械的に
+	  出来るため.
+
+Tue Aug 23 18:08:33 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c: スクリプト実行開始前に例外が発生した時にcore dumpした.
+	  組み込み用にコードを変更した時にenbugしてしまった.
+
+Tue Aug 23 00:07:17 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c: doの戻り値がいつもnilになっていた.
+
+	* parse.y: loop制御変数の多重代入化にbugがあった.
+
+	* parse.y(expand_op): 文字列も畳み込みの対象に.
+
+Mon Aug 22 10:50:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(expand_op): `+'に関しては結合則を使って, より多く定数畳
+	  み込みを行なうように.
+
+	* ruby.c(proc_options): argcが0の時にも対応.
+

+
+Sat Aug 20 00:59:40 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y(call_op): 演算子`~'の取り扱いをルール部へ移動.
+
+Fri Aug 19 11:44:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* main.c: rubyをほかのプログラムに組み込めるようにmain()を分割した.
+	  それにともない, プログラムの呼び出し構造を修正した.
+
+	* parse.y: 条件式の定義を変更. ifなどの条件式の中でだけ`&&'や`||'
+	  および`!'の引数が条件式になるように. この変更により条件式以外の
+	  場所での `&&', `||', `!'演算子の動作が直観に一致する.
+
+	* parse.y: 実引数の`*'の後に続く引数はexprに制限した. 今までは全て
+	  の文が有効であったが, ここで定義文があってもしょうがない.
+
+Thu Aug 18 10:21:45 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* re.c: 正規表現ルーチンの初期化部分を削除してしまっていた. これで
+	  はemacsの正規表現になってしまう.
+
+	* version.c: copyright表示を追加.
+
+	* version.c: バージョン表示をstderrに.
+
+	* configure.in: gccがない場合testに失敗していた.
+
+Fri Aug 12 14:12:23 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* array.c(astore): 配列の拡大する時にある程度の大きさをまとめて拡
+	  大するように.
+
+	* io.c(Fprint): 配列に対しては一度文字列に変換することなく, 直接内
+	  容を出力するように.
+
+	* string.c(str_new): memmoveからmemcpyへ置き換えた. これでもかなり
+	  速度が違う.
+
+	* ruby.h: データメンバの取り出しで名前を文字列からIDで指定するよう
+	  にした. かなりの高速化になる.
+
+	* io.c: $ARGFという変数で引数列からなる仮想ファイルをオブジェクト
+	  として扱えるようにした. 今まではトップレベルのgets()などを使って
+	  アクセスしていたが, どうもオブジェクト指向的ではなかった.
+
+Thu Aug 11 11:43:15 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* gc.c: mark_location()の間違った呼び出し方の行が残っていた.
+
+	* method.c: プロトタイプ宣言が足りなかった.
+
+Wed Aug 10 15:54:46 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* variable.c: -vオプションが指定されている時は初期化されていない,
+	  大域変数, インスタンス変数, ローカル変数を参照した時点でwarning
+	  を出すようにした.
+
+Tue Aug  9 11:50:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* bignum.c: 冪乗に関しても多倍長演算を行なうように. 特に浮動小数点
+	  数の範囲を越えた時の処理を的確に行なうように.
+
+	* eval.c: メソッド定義後は構文木から, メソッド定義部分を外す. 無駄
+	  な再定義が起こらないようにするためと2重にfree()されないため.
+
+	* array.c(Fary_aref): 引数が1つでFixnumの時, Range checkを行なわな
+	  いように修正.
+
+	* eval.c: メソッドの引数の数をコンパイル時に計算して若干の高速化.
+
+Mon Aug  8 13:06:24 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* object.c: nilによる比較連鎖をなくした.
+
+	* parse.y: bit演算子の優先順位を比較演算子よりも強くした.  Cとは異
+	  なることになるが, 直観には合致する.
+
+	* gc.c: クラスを解放する時, 個々のメソッド毎にキャッシュをクリアす
+	  るのではなく, クラス単位でクリアするように.
+
+Thu Aug  4 18:45:09 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* methods.c(method_free): 解放されたメソッドに関してキャッシュをク
+	  リアしておく必要があった.
+
+	* gc.c: Dataクラスのデータ部分をfree()し忘れていた.
+
+Wed Aug  3 09:58:14 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: def func .. end形式による関数メソッドの定義はなくなった.
+
+	* methods.c: func形式のメソッドをなくした. あっても, あまり意味が

+
+	* eval.c: $0への代入でps(1)の出力が変化するように.
+
+	* io.c(Fsyscall): syscall()を実現.
+
+Mon Aug  1 13:41:11 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: ダブルクォートで囲まれた文字列や正規表現中で"#{変数名}"
+	  または"#変数名"という形式で変数の内容を埋め込むことができるよう
+	  になった.
+
+	* io.c: 関数メソッドsystem2()はなくなった. 今はバッククォートがあ
+	  るからね.
+
+	* parse.y: `cmd`によってコマンドを文字列に展開することができるよう
+	  になった.
+
+	* parse.y: __FILE__, __LINE__を追加. それぞれファイル名(文字列),
+	  行番号(整数)を値とする疑似変数.
+
+Fri Jul 29 13:16:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* methods.h: メソッドをオブジェクトとして扱うのをやめる. メソッド
+	  のメモリ管理にはリファレンスカウントを使うことにした. これでオブ
+	  ジェクトの数が減ってほんの少しだけGCが速くなる(かな).
+
+	* purifyによってメモリ関係のバグを検査した(見つかる,見つかる…).
+
+	* gc.c: GCをプログラマが変数をマークする形式から, スタックとレジス
+	  タからマークする方法に変更. 移植性が下がるような気もするが, siod
+	  やscmでも採用されているから多分大丈夫だろう. Linux on i486でも動
+	  作を確認した.
+
+Wed Jul 27 16:13:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Eval): トップレベルでは構造木をfreeしないように. どうせ解
+	  放されるから時間の無駄である.
+

+
+Fri Jul 22 10:14:09 1994  Yukihiro Matsumoto  (matz@ix-02)

+
+Thu Jul 21 14:06:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(freenode),eval.c(Eval): 解析木を解放し忘れていた.
+
+Mon Jul 18 10:19:15 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: 多重代入を処理するルールにバグがあって, 3要素以上の多重
+	  代入に失敗していた.
+
+	* eval.c(rb_eval): 多重代入で, 右辺が配列でない時には`to_a'メソッ
+	  ドで配列に変換して代入するようにした. 今までの仕様だと右辺値が第
+	  1要素にそのまま代入されていたが, structなど配列に変換できるもの
+	  は変換した方が嬉しい気がする.
+
+	* dbm.c,dict.c(delete_if): メソッド追加.
+
+	* process.c(wait,waitpid): システムコールwaitpidまたはwait4がある
+	  時はそちらを使うように. configureもそれらをチェックするように変更.
+

+
+Fri Jul 15 10:54:45 1994  Yukihiro Matsumoto  (matz@ix-02)

+
+	* string.c(Fstr_split): $;の値が長さ1の文字列である時, これを正規
+	  表現化しないで, 単なる文字として分割する.
+
+	* string.c(Fstr_aset/Fstr_aref): インデックスが文字列の範囲外だっ
+	  た時の動作をArrayを参考に修正した.
+
+	* array.c(astore,Fary_aset): 領域をreallocした後, ゼロでクリアする
+	  ように. 今まで配列にゴミが入っていた.
+
+	* array.c: []/[]=でのインデックス関係を整理. 基本的に負のインデッ
+	  クスに代入しない限り例外は起きないように変更した. 必要に応じて適
+	  当に解釈して, 必要ならば領域を拡張するように.
+
+Thu Jul 14 11:18:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* autoexec.c: 削除. autoload関係の機能は今後検討しよう.
+
+	* dict.c: 辞書クラスの正式名称をDictに変更した. 別名としてHashを用
+	  意した. 今までDictionaryなどと長い名前にしていたが誰も使っていな
+	  かったしね. *BACKWARD INCOMPATIBILITY*
+
+	* parse.y: Dictを生成する構文を追加. こちらを{..}にした.
+
+	* parse.y: 配列を生成する構文を[..]に変更した. 過去のRubyスクリプ
+	  トとの互換性が保てないが, Dictを生成する構文を導入するに当たり,
+	  perl5に合わせて(意識して), 変更する時期は今しかないと考えた.
+	  *BACKWARD INCOMPATIBILITY*
+
+	* eval.c(Feval): eval()でメソッドを定義する時, 定義されるクラスを
+	  メソッドの所属するクラスにした. 今まではObjectクラスに定義されて
+	  いた.
+
+	* parse.y: ローカル引数がない時のeval()で落ちていた.
+
+Tue Jul 12 09:41:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* pack.c: uuencode形式のサポート.
+
+	* `-0'を`-R'に. 出力レコードセパレータをコマンドラインから指定する
+	  方法はなくなった. どうも, 仕様がゆれるなあ.
+
+Mon Jul 11 09:51:24 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.c: `-r'オプションは`-0'オプションになった. 当面は`-r'も有効
+	  だが変更される可能性がある. `-R'は当面はそのまま.
+
+	* version.c: version表示に日付を含めた.
+
+	* parse.y: private methodの復活. RubyのprivateメソッドはC++におけ
+	  るprotected methodに該当するもので, `@'で始まる名前を持つ.
+
+	* env.h: struct ENVIRONの定義を分離.
+
+	* parse.y: `\$var', `\@var', `%var'も許すように.
+
+	* variable.c(Fdefined): idも引数として受け付けるように.
+
+	* parse.y: if文/unless文にキーワードthenを追加. thenなしというのは,
+	  意外と間違いが多いので. もちろん省略できる.
+
+Sat Jul  9 02:16:04 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(rb_eval): class/moduleの評価で新しいスコープを割り当てて
+	  いなかった. スコープ割り当て部分をrb_call()からrb_eval()に移した.
+
+	* eval.c(rb_call): realloc()に渡される事のある, ローカル変数用の領
+	  域をalloca()していた. たまに落ちるわけだ.
+
+	* string.c(Fstr_times): 割り当てた領域を越えた部分を変更していた.
+
+Wed Jul  6 15:52:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* socket.c: Socket -> BasicSocket, RawSocket -> Socket に改名.
+
+	* string.c(ucfirst,lcfirst): 最初の1文字だけの大文字/小文字変換.
+
+	* numeric.c(chr): 整数の文字列化メソッド.
+
+	* inits.c, dbm.c: DBMが使えない時はクラスそのものを定義しないよう
+	  にした.  利用できないクラスはnilとすることを今後のポリシーとしよ
+	  う(いままではアクセスした時点でエラーが発生していた). autoexec()
+	  のあり方も検討が必要になりそうだ.
+
+	* bignum.c(bigadd): バグ修正.
+
+Thu Jul  7 11:12:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Fload,Feval): eval_treeをクリアし忘れていた.
+

+	  出力用).
+
+Wed Jul  6 00:57:18 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* numeric.c, bignum.c: 整数に対する`[]'演算子. nビット目がセットさ

+
+Tue Jul  5 12:48:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* io.c(Feof): 追加. コマンドラインからなる仮想ファイルについても
+	  EOFが検出できるように.
+
+	* ruby.c: -l/-r/-R/-Xオプションの追加.
+
+	* ruby.c: -n/-pオプションのloopの付加などをメインルーチンに移動し
+	  た. これで, オプションの解析途中で(`-c'オプションのせいで)終了な
+	  どといったことはない.
+
+	* io.c(Fgets): 高速化. 凝ったことをしない方が速かった. 虚しい.
+
+Mon Jul  4 15:55:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Socket:getsockname/getpeername - ようやく仕様が安定した.
+
+	* io.c(Fgets): eachでgetsを記述するのではなく, getsでeachを記述す
+	  るようにした.
+
+Fri Jul  1 10:35:49 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* $ENV[env] = nil/$ENV.delete(env)で環境変数を削除できるようになっ
+	  た. $ENV.deleteは環境変数の以前の値を返す.
+
+	* !~の定義が間違っていた.
+
+	* Dict,DBM:[]= - nilの代入によって要素を削除できるようになった. こ
+	  れにともないnilはDictの要素になれなくなった.
+
+	* ソースの整理. 盲腸のような使われていないコードをなくしたり, 変数
+	  名を付け変えたりした.
+
+Fri Jul  1 00:21:29 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Array:join() - 要素数0の配列に対して空文字列を返す.
+
+	* RawSocket:open(),socketpair() - 文字列で指定できるドメインとタイ
+	  プをいくつか追加した.
+
+Thu Jun 30 13:51:29 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* -fオプションをなくした. 昔(loadのなかった頃)の名残なので, 今となっ
+	  ては必要ないだろう.
+
+	* -sオプションを追加. perlの-sオプションと同じ動きをする.
+
+	* RawSocketクラスを提供する. Socketに対するシステムコールレベルの
+	  アクセスが可能になった.
+
+Thu Jun 30 00:27:19 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Socket - bug fixes.
+
+	* linuxではsyscall(SYS_select)が正常に動作しない.
+
+	* Socket:addr,peeraddr - 配列としてsockaddrの情報を返す.
+
+Wed Jun 29 00:14:20 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Socket:setopt,getopt - setsockopt(2), getsockopt(2)へのアクセス
+	  を実現.
+
+	* sprintf() - rubyにはunsignedは無いので, %uを取り除いた.
+
+	* sprintf() - %b, %x, %oでは2の補数表現, %B, %X, %Oでは符号付き表
+	  現で出力するように. ここ数日でsprintf()の仕様がゆらいでいたが,
+	  これで落ち着きそうだ.
+
+Tue Jun 28 14:42:03 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Bignum:<<,>> - 2の補数をとる処理を除いた. シフト演算には関係ない
+	  処理だった.
+
+	* Bignum:^ - bug fix. 符合が反対だった.
+
+	* sprintf() - 2進出力子"%b"を追加.
+
+	* sprintf() - %x, %oでFixnumを出力する時, 2の補数表示を行なわない.
+
+	* sprintf() - %x, %oはやはり負の数の時は`-'を出力するように.
+
+Mon Jun 27 14:56:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* sprintf() - Bignumについても%d, %oは(2の補数表現に変換して)正の
+	  整数を表示するようにした.
+
+	* Bignumに対する論理演算の定義を修正した. 負の数は2の補数表現であ
+	  るとみなし, かつ仮想的に左側に無限に1が連続しているような演算結
+	  果を得る.
+
+	* Fixnum:<<,>> - 符合付シフトに変更.
+
+	* Bignum:>> - 負の整数のシフトに対応した.
+
+	* __END__, ^D, ^Zでスクリプトを終了できる.
+
+	* -xオプションを追加. #! ..rubyなる行まで読み飛ばす.
+
+	* -cオプションを追加. コンパイルのみを行う.
+
+Sat Jun 25 01:37:21 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Fixnum:<< - 必要に応じてBignumに拡張して左シフトするように. よっ
+	  て, シフト幅が32を越えるとCやPerlとは違った値を返す.
+
+Fri Jun 24 10:01:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ioctl()/fcntl() - システムコールを呼び出す前にバッファの大きさを
+	  調節するようにした.
+
+	* String:toupper/tolower - 文字列を置き換えたコピーを作るのではな
+	  く, 元の文字列の内容を変更するようにした.
+
+	* inplace editを実現した. perlと同じように`-i'オプションで指定する.
+	  もっとも, こちらはMS-DOSのこととか考えてないけど.
+
+	* デフォルトの出力先を追加した. 今までは$stdoutに代入するしか方法
+	  はなかった.
+
+Fri Jun 17 10:55:08 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 環境変数にアクセスする方法としてgetenv()/setenv()以外に$ENVを用
+	  意した. $ENVは文字列-文字列の辞書であるかのように動作するEnvDict
+	  オブジェクトが代入されている(eachはassocを与える).
+
+	* nilに代入するとcore dumpした. コンパイル時のチェックを強化.
+
+	* Struct: struct_new()の引数をGCプロテクトする必要がある. せめてス
+	  タック領域だけでもスキャンできるようにしなければいけないんだろう
+	  か? でも, 移植性がなあ.
+
+Fri Jun 17 01:01:46 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Time::asctime() - 日付のフォーマットで日が落ちていた.
+
+	* Stat: StatはEtcなどと同様にStructで実現したので, Statクラスは無
+	  くなった.
+
+Thu Jun 16 10:32:23 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* bignum.c: いくつかのバグを修正した. Fixnumを渡すべきところで普通
+	  のintを渡していた. 失敗.
+
+	* big2str() - 1桁ずつbaseで割る代わりに, 4桁ずつ割算を行なうように
+	  した. これで多倍長割算の回数が1/4になる. さらに整数->数(文字)へ
+	  の変換をテーブルを用いるようにした.
+
+	* rb_ivar_get_1() - すでに何らかのインスタンス変数を持つオブジェク
+	  トでは, 未定義のインスタンス変数の値が不定値になっていた.
+
+	* yylex() - インスタンス変数の認識に失敗していた. attr()は正しく動
+	  作していたので, 混用すると動作しなかった. 全部違っていたから動い
+	  ていたのね.
+
+	* Object:attr() - すでにアクセスメソッドが定義されている時にはデフォ
+	  ルトのアクセスメソッドを定義しないようにした. もっともアクセスメ
+	  ソッドと同名のメソッドの区別はRubyには存在しないけど, それは仕方
+	  がないよね.
+
+	* pack.c: エンディアンをautoconfで判定するようにしたので, v/Vが使
+	  えるようになった. またntoh?()/hton?()も自前で用意した.
+
+	* Stat: st_rdevをアクセスするメソッドを追加. さらにシステムがstat
+	  構造体にst_blksize, st_blockを持っているかをautoconfでチェックす
+	  るようにした.
+
+	* ドキュメントを少し整備した.
+
+	* INT2FIX()のうち, 31bit幅が保証できないものは, int2inum()に置き換
+	  えた.
+
+Wed Jun 15 10:18:27 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* sprintf() - bignumの出力の時, 出力幅を正しく計算するようにした.
+
+	* str2inum() - baseが0の時, baseを自動判定するように(0xで始まる時
+	  16 進, 0で始まる時8進).
+
+Tue Jun 14 16:08:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* gc.c: Bignum型を追加するのを忘れていた. 組み込み型を追加した時に
+	  は必ずmark()とsweep()にその型に関する処理を追加する必要がある.
+
+	* bignum: 割算も動いたような気がする. アルゴリズムを理解していない
+	  ので, 自信がない.
+
+Mon Jun 13 14:36:55 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* まだサポートしていないメソッドなどがあるが, 曲がりなりにもBignum
+	  が使えるようになる. これでioctlも使える.
+
+Fri Jun 10 17:26:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Comparable: 基礎となるメソッドを`=='と`>'から`<=>'に変更した. 今
+	  後Comparableのサブクラスは`<=>'だけを再定義する必要がある.
+
+Wed Jun  8 13:12:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Need_Fixnum()をほとんどなくして, NUM2INT()で直接intに変換するこ
+	  とにした. これで31bitに丸めて桁落ちをおこす問題がなくなる.
+
+Tue Jun  7 09:45:31 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.h: マクロFIXABLE(n)を追加. ついでにFIXNUM周りの定義を変更し
+	  て, 移植性を高めた(つもり).
+
+	* C++の予約語であるnewを削除した. しかし, もうひとつの予約語である
+	  classに関しては, 置き換える単語が思いつかないこともあってそのま
+	  まになっている.
+
+	* 31bitを越えそうなINT2FIX()を関数呼び出しに変えた. 将来bignumが導
+	  入された時には自動的にbignumを返すようにする.
+
+	* readline() - 引数の`-'は標準入力を意味するようになった.
+
+	* ruby.h: 右シフトが論理シフトか算術シフトかは処理系依存のようなの
+	  で, ruby.hでcppを使ってチェックするようにした. これでうまくいく
+	  と思うのだが, 手元に符合付intを論理シフトする処理系がないので確
+	  認できない. NEWS-OSのCCは確か右シフトはいつも論理シフトだったよ
+	  うな気がするんだけど….
+
+Mon Jun  6 10:10:22 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* FIX2INT()の定義を変更した. どうして昔はうまく動かなかったんだろ
+	  うか? もしかして, 右シフトの符号拡張は処理系依存?
+
+	* FIX2INT()とFIX2UINT()を使い分けるようにした. もっともfixnumは31
+	  ビットしかないので, 本質的な解決にはならないのだが(ioctlが組み込
+	  みたかった).
+
+	* printを関数的メソッドから通常メソッドに変更. 引数が与えられない
+	  時にはレシーバをプリントするようにした. これでprintをメッセージ
+	  形式でも実行できるようになった. 例:
+
+		ruby -e 'readlines().sort.print'
+
+	  上のスクリプトは, 引数として与えられた(あるいは標準入力から読み
+	  込まれた)文字列を各行毎にソートして表示する.
+
+	* eval.c: argc,argvパターンで引数を受けるメソッドに引数が一つも与
+	  えられない時, argvがnilになっていた(argv[0]にアクセスすると落ち
+	  てしまう).
+
+	* _exit()を追加. こちらは例外処理など行なわない.
+
+	* dbmクラス: クラス名称をDBM(大文字)に統一した.
+
+Sat Jun  4 00:51:04 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* ループ変数にも属性や配列要素を指定できるようにした.
+
+Fri Jun  3 09:49:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 多重代入において, 属性代入, 配列要素への代入も行なえるようにした.
+
+	* Need_Fixnum(): nilを0に変換するように.
+
+	* Enumerable:min, max, index, includes - 追加. min, maxは要素が
+	  `<=>'メソッドを持つことを仮定している.
+
+	* Dict/Dbm:length - 要素数を返すメソッド.
+
+	* Dbmクラスにto_aメソッドを追加.
+
+	* Sunにおけるsortの誤動作の件, 昨日の修正でfixされた. しかし, それ
+	  でなぜ動かなかったのかは明らかではないが…. 比較関数がどんな値を
+	  返しても指定した領域外をアクセスするのはバグではないか.
+
+	* ファイルの全内容を読んで, 各行を配列として返すメソッドはpythonを
+	  参考にして`readlines'という名前にした. それにともないgetsに対し
+	  てreadlineという別名を用意した.
+
+Fri Jun  3 00:08:38 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Array:sort - 判別関数の戻り値はFixnumではなく, Intであるべきだっ
+	  た. 間違い. Sunで動作がおかしかったのはこのせいかも知れない.
+
+Thu Jun  2 11:48:37 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* IO:read_all() - ストリームの最後まで入力して, 各行を要素とする配
+	  列を返すメソッドを追加. また関数メソッド read_all()も追加した.
+  	  これは引数のファイルから読み込んで各行を要素とする配列を返す. 意
+	  味的には
+
+		def read_all()
+	  	  ary = {}
+	  	  while gets()
+		    ary.push($_)
+		  end
+		end
+
+	  とほぼ等価である.
+
+	* String:atoiメソッドを削除. to_aメソッドからaが配列であるとの連想
+	  を呼んで, 混乱を招かないため. 代わりにto_iメソッドを使うこと.
+
+	* 配列への変換メソッドto_aを導入した. 通常のオブジェクトは自分自身
+	  を唯一の要素とする長さ1の配列を返す. 配列は自分自身を, 辞書はキー
+	  と値のペアの配列を返す. Enumeratedをincludeしたクラスは, eachが
+	  返す各要素を含む配列を返す.
+
+	* file.c: 不定個の引数を受けとるメソッド(chmod,chown,utimes)を書き
+	  換えて, 整理した. それに伴い, 最初に全ての引数の型チェックを行な
+	  うようにした. 型チェックに失敗すると処理を行なわずに例外を発生さ
+	  せる.
+
+	* configure.in: 不必要なテストを行なわないように修正した.
+
+Tue May 31 10:41:08 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* String:pack(): 2進数の文字列変換(B,b)で0と1が逆だった.
+
+	* Math.c: 実数系のメソッドに引数として整数が渡された時に自動的に変
+	  換するようにした.
+
+	* toupper(), tolower(): 文字列の判定ミスで変換されていなかった.
+
+	* getopt_long()の仕様によって, スクリプトへの引数がインタプリタの
+	  引数だと解釈されていた. 引数パターン文字列の先頭に`+'を追加.
+
+	* config.hを削除した. DEFINEはMakefileで与えられる.
+
+	* sprintf(): "%d"に文字列が与えられた時にはアドレスではなく内容を
+	  整数に変換するようにした. ついでに浮動小数点数も変換するように変
+	  更した.
+
+	* regexp.c: rubyの拡張正規表現(\d, \D, \s, \S)の処理で割り当てた領
+	  域を越えてバッファに書き込んでいた. 処理前にバッファをきちんと拡
+	  張するようにした. これで昨日問題にしていたメモリの問題は解決でき
+	  たと思う.
+
+	* yylex(): ダブルクォート文字列中でダブルクォートを表現するため
+	  のバックスラッシュ表現ができなかった.
+
+Mon May 30 10:07:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 演算子`!'の右辺も条件式であるとした. これによって, この演算子を
+	  再定義する人は混乱するかも知れないが, 大多数のこの演算子を使う人
+	  は混乱を避けることができると思う.
+
+	* autoconfを使って, 自動的にMakefile, config.hを生成するようにした.
+	  これで, 多くのマシンでは`configure'を実行した後, `make'一発でコ
+	  ンパイルできると思う.
+
+	* clone: サブクラスに対して用いられた場合, 元のオブジェクトと同じ
+	  クラスのインスタンスを返すように(以前はビルトインクラスの場合を
+	  考えてなかった).
+
+	* ビルトインクラスのサブクラスも作れるように, リテラルのあるクラス
+	  にもnewメソッドを追加した.
+
+	* malloc()で落ちる. purifyが必要かも知れない.
+
+	* re.c: rb_global_variable()の呼びだし形式の間違い. 変数へのポイン
+	  タを渡さなければいけない.
+
+	* parse.y: ローカル変数の扱いに引数の評価順に依存する移植性のない
+	  部分があった.
+
+	* attr(): 属性設定のバグを直した. いつ内部仕様が変わったんだろう…?
+
+Sat May 28 23:08:18 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 正規表現キャッシュの文字列一致判定をポインタ一致から内容一致に変
+	  更した. そういえば文字列リテラルは一回毎に新しくオブジェクトが生
+	  成されるのだった.
+
+Fri May 27 11:42:00 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* trから文字削除(delete), 文字圧縮(squeeze)を分離した. それにとも
+	  ないtrのオプション引数はなくなった.
+
+Thu May 26 10:32:55 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* スクリプト読み込みルーチンを書き直して, 通常ファイル以外のファイ
+	  ル名や空文字列がスクリプトとして与えられた場合に対応した. また,
+	  標準入力からスクリプトを読み込む時に, 一時ファイルが/tmpに残らな
+	  いようにした.
+
+	* Fixnum:id2name - IDから文字列に戻す関数. String:internの逆.
+
+	* Array: 配列の範囲外の要素をアクセスした時に例外を発生させずに,
+	  nilを返すようにした. 配列は自動的に拡張される.
+
+	* string:stripを追加.
+
+	* -nオプションが-eオプションを複数指定した時も動作するように.
+
+	* parse.yで<sys/types.h>もインクルードするようにした.
+
+	* fname周りの細かいbugを修正.
+
+Wed May 26 11:45:10 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 定数をキャッシュするようにした. 繰り返しが多い場合には有効のはず
+	  だが, 一度しかアクセスしない場合は遅くなるなあ.
+
+Wed May 25 00:42:24 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 多重代入文(foo, bar = 1, 2)の採用.
+
+	* 条件式部に文字列あるいは正規表現リテラルをおくと`=~'演算子によっ
+	  て`$_'と比較される. 更に`...'の両辺では整数リテラルが`$.'と比較
+	  される.
+
+Mon May 23 23:27:03 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* &式 形式はなくなった. 代わりにkernel:apply(id, args..)を導入.
+
+	* def op () ..形式の導入. opは再定義可能な演算子.
+
+	* constantの代入時チェック. 既に初期化されている定数に代入した場合
+	  は例外が発生する.
+
+	* 多重代入文.
+
+Thu May 19 22:57:07 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 複合文でもvoid valueのチェックを行うようにした.
+
+	* untilの動作の修正(do..until型だった).
+
+Wed May 18 01:06:25 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 移植に関する若干の問題を修正.
+
+	* 別名の構文を「def a b」にした.
+
+	* until/unless: 演算子から制御文へ. 例外を捕捉する機能はそのまま.
+
+	* 選択可能な機能をconfig.hからdefines.hに移動.
+
+Fri May 13 23:20:21 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* -yオプションを新設. -dオプションからコンパイラのデバッグ部分を分
+	  離した.
+
+Tue Apr 25 20:17:33 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* マルチバイト文字列を識別子に使えるように. 個人的には使いたくは無
+	  いけどなあ.
+
+	* `-v'フラグの状態を$verboseでアクセスできるように.
+
+	* CVSの導入に伴い, バージョン管理の方法を変更.
+
+	* 真面目にChangeLogをつける事にした.
+
+Tue Mar  8 10:09:25 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* %変数名 によるクラス定数を導入.
+
+	* undef メソッド によるメソッド定義の取り消しを導入.
+
+	* rb_get_method_bodyではthe_envを変更せず, rb_call()で明示的に変更
+	  するように. これでresponds_toなどで環境が破壊されない.
+
+Mon Mar  7 17:46:15 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* 「&文字列」形式. 「式.文字列」型のメッセージセンドはなくなった.
+
+	* 自己代入形式(+=. -=, ...)
+
+	* obj.attr = expr形式の採用.
+
+Thu Feb 24 16:23:28 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* toint, tofloat, print_stringをそれぞれto_i, to_f, to_sに変更.
+
+	* String:clone - Copy on Writeの実現.
+
+Tue Feb 22 11:11:44 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* re.c: マッチした文字列の保存に失敗していた.
+
+	* trap: 可能ならば処理に時間のかかるシステムコール(read, wait,
+	  sigpause, select)をフックして割り込み処理の即答性を高める(DOSな
+	  どでは無理だなあ).
+
+	* trap: 割り込みをその場で処理するか(迅速だが危険), 安全なタイミン
+	  グで処理するかを選択できるように.
+
+Tue Feb 17 11:11:12 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* trap: 割り込みハンドラ.
+
+Wed Feb 16 12:29:12 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* String:crypt: 暗号化ルーチン
+
+	* "::"演算子の追加. a::b は {a, b}と同義. a::b::c は {a, {b, c}}と
+	  同義(右結合). 同義とはいうものの, "::"演算子を使った方が少しだけ
+	  メモリ効率が良い.
+
+	* Dir.rmdir(), File.unlink(), File.utime() -- 各システムコールへの
+	  インタフェース.
+
+	* kill -- kill(2) I/F
+
+	* select(): readのチェックではstdioにバッファリングされているかど
+	  うかをチェックするように.
+
+Tue Feb 15 15:08:31 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* file.c: statをキャッシュするように.
+
+	* File:utime()を追加.
+
+	* unliteralize(): フラグを破壊していた.
+
+	* Bug(): coreを吐くように.
+
+	* String:tr -- tr(1)互換. 引数パターンがちょっと違うけど….
+
+Mon Feb 14 18:24:13 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* unless, untilが例外も偽と見なすように.
+
+	* select() -- select(2) I/F
+
+	* Array:pack, String:unpack: perlのpack/unpackの同等品
+
+Tue Feb  8 17:11:10 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* setenv()のないシステムのためにputenv()を使ったコードも用意した.
+
+Mon Feb  7 09:52:44 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* 引数の一番最後に`*'を置けるようにした. これでrest引数のリストを
+	  操作する必要が少なくなる.
+
+Fri Feb  4 18:23:26 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* ruby-mode.elを書き直す. ずいぶんましになったと思う.
+
+	* 文字列リテラルのCopy on Writeを実現. これで文字列がリテラルであ
+	  るからといっていちいちcloneしなくても済む.
+
+Tue Feb  1 09:21:09 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* sub(), gsub()で, マッチした文字列を$&, $1..$9でアクセスできるよ
+	  うにした. 同時にマッチした部分文字列をコピーしておくように(元の
+	  文字列が変更されても状態を保存するため).
+
+Mon Jan 31 15:16:58 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* プライベートメソッドの仕様を変更. 今までは同じクラスのメソッドか
+	  らしかアクセスできなかったが, サブクラスのメソッドからもアクセス
+	  できるようにした(C++におけるprotected メンバ関数).
+
+	* メソッドサーチのアルゴリズムを改善し, 10%程度の高速化を行なった.
+
+	* 高速化. Cで記述されたメソッドを呼び出す時にはsetjmpを呼ばないよ
+	  うにした. これでCメソッドを多用する場合には3倍程度高速になった.
+
+Fri Jan 28 15:44:04 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* sh-modeを元にruby-mode.elを作る. 演算子で終る, 2行に渡る文には対
+	  応していないけど….
+
+Thu Jan 27 11:35:19 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* freenode(): NODE_NILの解放忘れ.
+

+
+Tue Oct 25 00:36:16 1994  Yukihiro Matsumoto  (matz@ix-02)

+	* socket.c(recvfrom): recvと同様だが, データと相手アドレスのペアを
+	  返す.
+
+	* socket.c(accept): 戻り値をつながったソケットから, ソケットとアド
+	  レスのペアに変更した.
+
+	* eval.c(eval): the_classをセットする時に, last_moduleがincludeさ

+	  能性があり, 不審な動作をする(はず).
+
+	* class.c: オブジェクトのcloneの際に特異クラス(特異メソッド用のク
+	  ラス)をきちんとコピーするようにした. 今までは個々のメソッドのコ

+	* object.c(export,unexport): 関数メソッドの設定用メソッド.
+
+	* eval.c, class.c: 関数的メソッドを復活させ(またか…), `@'による

+	   *BACKWARD INCOMPATIBILITY*
+
+	* eval.c: メソッドの構成を変更し, 別名管理と関数メソッドの管理を分
+	  離した.
+
+	* eval.c: the_env->last_funcをCメソッドの時にも更新する. これがな

+	* eval.c(SETUP_ARGS): 付加引数が配列でない時には配列に変換する.
+
+	* parse.y: 括弧なしのメソッド呼び出しでも`*'による付加引数が使える
+	  ようにした. ただし, 通常引数が一つもない場合は乗算演算子と区別が
+	  つかないので, 必ず括弧が必要.
+
+Wed Oct 12 10:09:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(rb_call): キャッシュの計算をinline化. キャッシュミスがあ
+	  れば関数呼び出しでメソッドを検索する. methods.cはなくなった.
+
+	* eval.c(rb_eval): ローカル変数用の領域をalloca()するように変更.
+	  サイズの変更が必要になれば改めてmalloc()するように.
+
+	* parse.y: error recoveryの際にlex_stateを更新しておくように.
+
+Tue Oct 11 17:10:46 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* socket.c(for_fd): ファイル記述子(Fixnum)からソケットインスタンス
+	  を得るメソッド. たとえばinetdから起動されたサーバで標準入出力に
+	  ソケット操作を行なうために使う. つまりSocket.for_fd($stdin)で標
+	  準入力に対応するソケットオブジェクトが得られる.
+
+	* io.c(to_i): IOクラスのインスタンスを整数に変換するとそのファイル
+	  記述子を返すように.
+
+	* numeric.c(num2int): to_iメソッドを使ってできる限り整数に変換する.
+	  以前はnum2fixだけが全てのオブジェクトに対してto_iメソッドを適用
+	  していた.
+
+	* sprintf.c(Fsprintf): 整数表示の際, オブジェクトをできる限り整数
+	  に変換するように(to_iメソッドを使う).
+
+Fri Oct  7 14:06:32 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Fcaller): 必要性がよく分からないのでドキュメントから削除.
+	  将来デバッガを作る時に復活させよう.
+
+	* eval.c(rb_call): Cで記述されたメソッド呼び出しでは環境をスタック

+
+Wed Oct  5 15:00:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.h: 一時env.hに移動してたQselfの定義を復活. ただし今回は関数
+	  として実現(env.hでは変数として再定義してある).
+
+	* ruby.h: TRUEでsyntax errorにならないよう#undefを追加.
+
+	* eval.c(rb_eval): thread化に挑戦したが, 失敗(速くならなかった).
+	  が, Scopingなどの無駄なコードの削除とメソッド呼び出しの引数セッ
+	  トのinline化で若干の高速化を実現した. 副作用として, argc, argv形
+	  式の関数呼び出しの仕様が変化した(argvにselfを含まなくなった).
+
+	* eval.c(rb_call): メソッド呼び出しの高速化.
+
+Tue Oct  4 11:40:53 1994  Yukihiro Matsumoto  (matz@ix-02)

+
+Mon Oct  3 15:58:41 1994  Yukihiro Matsumoto  (matz@ix-02)

+
+	* object.c: デフォルトの真の値である%TRUEの値を1(Fixnum)からtに変
+	  更した. to_sで文字列に変換した時にも`t'と表示される. 更に踏み込
+	  んで`t'を予約語にしてlispのようにしようかとも思ったが, そこまで
+	  は決心できなかった. 一文字のローカル変数はかなり使いそうな気がす
+	  るので….
+
+	* array.c,dict.c: equalを再定義しているクラスで, hashを正しく定義
+	  した.
+
+Wed Sep 28 23:30:28 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(Ffail): 今までfailはカーネルクラスのメソッドであったが,
+	  構文に組み込んだ. この変更によって, 1)`fail'は予約語となり, ロー
+	  カル変数に用いることができなくなった. 2)`fail'単体で例外を発生す
+	  るようになった. 3)failはメソッドではなくなったので再定義される可
+	  能性がなくなった.
+
+	* dic.c, dbm.c(indexes): Arrayのindexesと同様の機能を持つメソッド
+	  を追加.
+
+	* array.c(indexes): 引数をインデックスとする要素の配列を返す. 整数
+	  の配列を引数とする時には引数の要素をインデックスとする要素の配列
+	  を返す.

+
+	* array.c(aset): 部分配列に対する代入で配列以外のオブジェクトが指
+	  定された場合に多重代入と同じルールで配列化するようにした.
+
+	* io.c(print): 引数として与えられた各オブジェクトにprint_onメッセー
+	  ジを与えるように. 実行速度は落ちるが柔軟性は増す.
+
+Fri Sep 16 14:59:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* glob.c: ワイルドカードの導入. bashに使われているGNUのglobルーチ

+
+	* parse.y(value_expr): 式がnilの時に対応.

+	* class.c: ICLASSのclassが必ずClass/Moduleを指すように.
+
+Tue Sep  6 16:23:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* re.c:	正規表現内で「\数字」形式が指定できるように.
+
+	* parse.y:「do expr using var ... end」形式はなくなった. 寂しい気
+	  もする. *BACKWARD INCOMPATIBILITY*
+
+Mon Sep  5 10:59:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* numeric.c(next): Numericクラスにもnextを提供.
+
+	* string.c(upto): uptoを提供.
+
+	* range.c(each): nextを使ったインタフェースからuptoを使うように変
+	  更した. この方が一つのメソッドで処理をまとめで行なうことができる.
+
+Fri Sep  2 15:25:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* dict.c(each): 戻り値を[key, value]のペアに変更. 今までのeachは
+	  each_valueとして残る. *BACKWARD INCOMPATIBILITY*
+
+Thu Sep  1 10:49:04 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 成功した(特別な戻り値を持たない)システムコールは`0'を返すように.
+
+Wed Aug 31 00:26:51 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* string.c: チェックサムを得るメソッド`sum'を作った.
+
+	* class.c(include_class_new): ICLASSのclassをもとのクラスにした.
+	  gcの際に元クラスをマークする必要があるのが, フィールドを増やす余
+	  地が無いので, classフィールドを流用した. 私の見積りが間違ってい
+	  て, ICLASSのインスタンスにメッセージを送る事があれば, おかしな動
+	  作をするだろう.
+
+	* eval.c(masign): 式(a,b = nil)の値を[nil]からnilに変更した.
+
+Mon Aug 29 11:56:09 1994  Yukihiro Matsumoto  (matz@ix-02)

+	  えば「if cond then a else b end.message()」のような式が書けるよ
+	  うになった.
+
+Fri Aug 26 10:46:30 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* spec: 整理された文法にしたがって書き直した.
+
+	* parse.y: ここ数日で混乱していた文法を整理した. 括弧を省略したメ

+	  である.
+
+	* process周りが怪しいがとにかくSolaris 2.3で動くように.
+
+	* parse.y: 曖昧性がない場合にはメソッド呼び出しの引数の括弧を省略
+	  できるように. 省略できるメソッド呼び出しの条件は, 1)かならず1個
+	  以上の引数を必要とすること, 2)第1引数が`+', `-', `(', `[', `{',
+	  `/'など, 式の始まりに置かれた時と途中に現れた時とで解釈が違う記
+	  号で始まらないこと, である.
+
+Thu Aug 25 13:54:58 1994  Yukihiro Matsumoto  (matz@ix-02)

+
+Wed Aug 24 00:01:15 1994  Yukihiro Matsumoto  (matz@dyna)

+	  return a, b, cはreturn [a, b, c]と同じ意味になる.
+
+	* parse.y: yield以外の大域脱出制御式をexprからexpr0に移した. よっ
+	  てメソッドの引数に制御式を使えなくなる(これで困る人はいないはず).
+
+	* parse.y: `+'の定数展開の際に演算子の優先順位を忘れていた.
+
+	* eval.c: untilの戻り値はnilになった.
+
+	* parse.y: modifierとしてのif/unless/while/untilを追加.
+
+	* parse.y: 文法からendの後ろにつけるキーワードを削除. ほとんど使わ
+	  なかった上に, emacsではruby-modeがあれば対応のチェックが機械的に
+	  出来るため.

+
+Fri Aug 19 11:44:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* main.c: rubyをほかのプログラムに組み込めるようにmain()を分割した.
+	  それにともない, プログラムの呼び出し構造を修正した.
+
+	* parse.y: 条件式の定義を変更. ifなどの条件式の中でだけ`&&'や`||'
+	  および`!'の引数が条件式になるように. この変更により条件式以外の
+	  場所での `&&', `||', `!'演算子の動作が直観に一致する.
+
+	* parse.y: 実引数の`*'の後に続く引数はexprに制限した. 今までは全て
+	  の文が有効

+	  RB_RESERVED_FD_P): added.  This C API is to limit to access
+	  fds which are used by RubyVM internal.  In this version of
+	  CRuby, return 1 if fd is communication pipe.
+	  If your application needs to close all file descriptors to
+	  present resource leak, skip internal fds using this C API.
+	  We also define a macro RB_RESERVED_FD_P(fd).  So you can write
+	    #ifndef RB_RESERVED_FD_P
+	    #define RB_RESERVED_FD_P(fd) 0
+	    #endif
+	  for Ruby 1.9.2 or previous version to write compatible extensions.

+
+	* lib/benchmark.rb: merge eregon/benchmark.
+	  https://github.com/eregon/ruby/tree/benchmark
+	  patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]
+
+	* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
+	  for the return value.
+
+	* test/benchmark: remove preemptive test instead of skipping
+	  I removed the preemptive test I wrote for Feature #4197.
+	  I'll add it back when the implementation will be able to satisfy it.
+
+	* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
+	  #format is an alias of #to_s test/benchmark: add a test for
+	  format of long time.
+
+	* lib/benchmark: fix label width: always add 1 to ensure there is a
+	  space delimiter even with times over 100s
+	  When I asked for Feature #4197, I wanted to make delimiting spaces
+	  consistent for #bm and #bmbm.
+	  But with times over 100s, the output contains no space between the
+	  label and the first time (user).
+	  Now both ensure there is always a space, even if that means 3 spaces
+	  with times under 10s (because it is formatted as %10.6f)
+
+	* test/benchmark: let labels be a constant
+	  lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
+	  lib/benchmark (Benchmark#benchmark): use ensure clause to restore
+	  STDOUT.sync, as in #bmbm

+	  several environment (we found a crash on FreeBSD).
+	  And remove const value "buff_size", and define CCP_READ_BUFF_SIZE
+	  macro.

+
+	* ext/syck/rubyext.c (mktime_do): avoid buffer overrun, by
+	  silently ignoring lesser significant digits.  Required buffer
+	  length can be computable so you might at first think of
+	  allocating enough memory space on the fly using alloca().  That
+	  is a wrong idea because when using alloca there is always risk
+	  of integer overflow.  A function that accepts outer-process
+	  resources like this should not blindly trust its inputs.  In
+	  this particular case we just want to generate milliseconds
+	  resolution by strtod() so the string in question needs no more
+	  length than what we originally have.  Ignoring lesser
+	  significant digits should suffice I believe.

+	  The problem is, you have to connect to the imaps server via
+	  the canonical name written in a server certificate, and that
+	  of the server.cert is "localhost".  So you have to listen to
+	  the address of what "localhost" resolves to.  I think this
+	  situation cannot be resolved in a handy manner because the
+	  test "test_imaps_post_connection_check" is actually
+	  expecting to connect to a server via an address other than
+	  the CN.  On my machine several assertions won't pass because
+	  the test cannot connect to the server.

+	  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on;
+	  those are attributes of event object). It means that Ruby/Tk accepts
+	  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but
+	  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }".
+	  It is potentially incompatible, when user passes symbols to the
+	  arguments of the callback block (the block receives the symbols as
+	  strings). I think that is very rare case (probably, used by Ruby/Tk
+	  experts only). When causes such trouble, please give strings instead
+	  of such symbol parameters (e.g. call Symbol#to_s method).

+
+	* ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets'
+	  instate/state/identify method to avoid the conflict with standard
+	  widget options. Those methods are renamed to ttk_instate/ttk_state/
+	  ttk_identify (tile_instate/tile_state/tile_identify are available
+	  too). Although I don't recommend, if you really need old methods,
+	  please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before
+	  "require 'tkextlib/tile'".
+
+	* ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!"
+	  is obsolete. It outputs warning. To control default widget set,
+	  use "Tk.default_widget_set = :Ttk".
+
+	* ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and
+	  __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defined
+	  as module methods of TkConfigMethod. It may help users to wrap old
+	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
+	  Ttk widgets don't have some options of standard widgets which are
+	  control the view of widgets. When set ignore-mode true, configure
+	  method tries to ignore such unknown options with no exception.
+	  Of course, it may raise other troubles on the GUI design.
+	  So, those are a little danger methods.
+
+	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__
+	  method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method
+	  are defined as module methods of TkItemConfigMethod as the same
+	  purpose as TkConfigMethod's ones.
+
+	* ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for
+	  wrapping old Ruby/Tk scripts (which use standard widgets) to use
+	  Ttk (Tile) widgets as default.
+
+	* ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state
+	  method instead of instate/state method.
+
+	* ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb,
+	  ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's
+	  are replaced to "instance_exec(self)".
+
+	* ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not
+	  a character code on Ruby1.9).
+
+	* ext/tk/lib/tk/variable.rb: support new style of operation argument
+	  on Tcl/Tk's 'trace' command for variables.
+
+	* ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix
+
+	* ext/tk/sample/demos-jp/textpeer.rb,

+
+	* ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command
+	  to make Tcl/Tk theme sources (based on different version of Tile
+	  extension) available.
+	  (Tk::Tile::__define_LoadImages_proc_for_compatibility__)
+
+	* ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames
+	  (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets
+	  as toplevel widgets.
+
+	* ext/tk/lib/tkextlib/tile/style.rb: ditto.
+	  (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__)
+
+	* ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get
+	  properties as a hash. metrics_hash method returns a boolean value
+	  for 'fixed' option. But metrics method returns numeric value
+	  (0 or 1) for 'fixed' option, because of backward compatibility.
+
+	* ext/tk/lib/tk/timer.rb: sometimes fail to set callback procedure.
+
+	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep
+	  doesn't block the eventloop. It will be better to use the method
+	  in event callbacks.
+
+	* ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep.

+
+	* ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set
+	  switchable between Tk (standard Tcl/Tk widget set) and
+	  Ttk (Tile). Initial default widget set is Tk. Now, toplevel
+	  widget classes are removed and defined as aliases.
+	  For example, "TkButton" is an alias of the "Tk::Button" class.
+	  Those aliases are replaced when switching default widget set.
+	  "Tk.default_widget_set=" is the method for switching default
+	  widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile)
+	  widget set as default. It means that "TkButton" denotes
+	  "Tk::Tile::Button" class. And then, "TkButton.new" creates
+	  a Tk::Tile::Button widget. Of course, you can back to use
+	  standard Tk widgets as the default widget set by calling
+	  "Tk.default_widget_set = :Tk", whenever you want. Based on
+	  the feature, you can use Ttk widget styling engine on your
+	  old Ruby/Tk application without modifying its source, if you
+	  don't use widget options unsupported on Ttk widgets (At first,
+	  call "Tk.default_widget_set = :Ttk", and next load and run
+	  your application).
+	  This is one step for supporting Tcl/Tk8.5 features.

+	  SyckParser's hash table. if GC occurs in st_insert, it's not under
+	  SyckParser's mark system yet. so RString can be released wrongly.
+
+	* ext/syck/syck.h (S_FREE): small hack. no need to check if pointer is
+	  NULL or not before S_FREE.
+
+	* ext/syck/rubyext.c (syck_parser_assign_io): rb_check_string_type can
+	  return new RString. if so, it becomes unreachable from GC after
+	  returns syck_parser_assign_io, and can be freed by GC. (dangling
+	  in syck io system) so extends its life time till syck_parse is called.
+
+	* ext/syck/rubyext.c (syck_parser_s_alloc): always allocates bonus,
+	  so no need to check if NULL, and "volatile VALUE hash"
+	  is not needed. (bonus->port was not protected in syck_emitter_reset)
+
+	* ext/syck/rubyext.c (syck_mark_parser): ditto.

+
+	* ext/syck/rubyext.c: sorry, I reverted my "should set newly
+	  allocated memory instead of RString's internal storage" stuff.
+	  node allocated in rubyext.c seems to be freed by rb_syck_free_node
+	  not syck_free_node, and it won't free data.str->ptr and type_id.
+
+	 (I still think this is unsafe because RString(foo)->ptr becomes
+	  dangling pointer when RString is modified or freed, but anyway
+	  I misunderstood, so go back to original code for now)

+

+
+Thu Oct  9 12:05:46 2003  Eric Sunshine  <sunshine@sunshineco.com>
+
+	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
+	  had become unbuildable; enhanced --enable-fat-binary option so that
+	  it accepts a list of desired architectures (rather than assuming a
+	  fixed list), or defaults to a platform-appropriate list if user does
+	  not provide an explicit list; made the default list of architectures
+	  for MAB (fat binary) more comprehensive; now uses -fno-common even
+	  when building the interpreter (in addition to using it for
+	  extensions), thus allowing the interpreter to be embedded into a
+	  plugin module of an external project (in addition to allowing
+	  embedding directly into an application); added checks for
+	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
+	  ensures that -I/usr/local/include is employed when extensions'
+	  extconf.rb scripts invoke have_header() since extension checks on
+	  NextStep and OpenStep will fail without it if the desired resource
+	  resides in the /usr/local tree; fixed formatting of --help message.
+
+	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
+	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
+	  (see configure's --enable-fat-binary option); added rule for new
+	  missing/getcwd.c.
+
+	* defines.h: fixed endian handling during MAB build (see configure's
+	  --enable-fat-binary option) to ensure that all portions of the
+	  project see the correct WORDS_BIGENDIAN value (some extension modules
+	  were getting the wrong endian setting); added missing constants
+	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
+	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
+	  define in NeXT section.
+
+	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
+	  NextStep since, on some installations, this value always resolves
+	  uselessly to zero.
+
+	* dln.c: added error reporting to NextStep extension loader since the
+	  previous behavior of failing silently was not useful; now ensures
+	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
+	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
+	  on Rhapsody since this header lacks multiple-include protection,
+	  which resulted in "redefinition" compilation errors.
+
+	* main.c: also create hard reference to objc_msgSend() on NeXT
+	  platforms (in addition to Apple platforms).
+
+	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
+	  makefiles so that extensions can be built MAB (see configure's
+	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
+	  (but not cpp_command() because MAB flags are incompatible with
+	  direct invocation of `cpp').
+
+	* ext/curses/extconf.rb: now additionally checks for presence of these
+	  curses functions which are not present on NextStep or Openstep:
+	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
+	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
+	  wscrl(), wsetscrreg()
+
+	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
+	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
+	  window_bkgd() to correctly return boolean result rather than numeric
+	  result; fixed window_getbkgd() to correctly signal an error by
+	  returning nil rather than -1.
+
+	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
+	  pointers before invoking rb_tainted_str_new2() upon fields extracted
+	  from `struct passwd' and `struct group' since null pointers in some
+	  fields are common on NextStep/OpenStep (especially so for the
+	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
+	  when it receives a null pointer.
+
+	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().
+
+	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
+	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
+	  (char*) for older platforms such as NextStep and OpenStep.
+
+	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup(); include
+	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
+	  argument of gethostbyaddr() and getservbyname() from (const char*) to
+	  non-const (char*) for older platforms.
+
+	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().

+
+	* vm.c: support variable VM/Machine stack sizes.
+	  Specified by the following environment variables:
+	    - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
+	      default: 128KB (32bit CPU) or 256KB (64bit CPU).
+	    - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
+	      creation. default: 512KB or 1024KB.
+	    - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
+	      default: 64KB or 128KB.
+	    - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
+	      creation. default: 256KB or 256KB.
+	  This values are specified at launched timing. You can not change
+	  these values at running time.
+	  Environ variables are only *hints* because:
+	    - They are aligned to 4KB.
+	    - They have minimum values (depend on OSs).
+	    - Machine stack settings are ignored by some OSs.
+	  Default values especially fiber stack sizes are increased.
+	  This change affect Fiber's behavior:
+	    (1) You can run more complex program on a Fiber.
+	    (2) You can not make many (thousands) Fibers because of
+	        lack of address space (on 32bit CPU).
+	  If (2) bothers you,
+	    (a) Use 64bit CPU with big memory, or
+	    (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
+	  You need to choose correct stack size carefully. These values
+	  are completely rely on systems (OS/compiler and so on).

+
+	* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.
+	  This method type is for optimized CFUNC such as Fixnum#+ and so on.
+	  This feature is half-baked and no way to use them.
+	  [Background]
+	  Now, VM has opt_plus instructions to optimize `+' methods for
+	  some Classes (such as Fixnum, Float (flonum)). We call this
+	  type of instructions as `specialized instructions'.
+	  This simple technique improve simple program dramatically.
+	  However, we can make specialized instructions for only several
+	  types (classes) and selectors (method names) because a large
+	  instruction will be slow. In other words, this technique has no
+	  extensibility.
+	  To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
+	  introduced (r37198). This type is a variant of CFUNC, but called
+	  their functions directly without building a method frame.
+	  Any CFUNC method can be defined as frameless methods if a method
+	  is not needed to make method frame. Frameless methods are faster
+	  as specialized instructions (a bit slower, but no need to care).
+	  No problem described at
+	  http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
+	  because this technique doesn't see class, but see method body
+	  itself. Alias is also no problem.
+	  [Problem]
+	  However, we can't set frameless method type for polymorphic methods
+	  such as Array#[]. Necessity for method frame depends on which
+	  parameter type. For example, Fixnum#+ needs method frame if
+	  coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
+	  flexible and need more tuning to introduce it.
+	  Expected behavior of frameless method type may be:
+	    result = optimized_cfunc(params); /* call optimized cfunc */
+	    if (result == Qundef) { result = normal_cfunc(); }
+	  This is why I say this feature is half-baked.
+	  We need to learn primitive method in Smalltalk more.
+	  (I heard this name at RubyConf Taiwan this month. Thanks!)
+	  [Conclusion]
+	  I remove this feature and consider again.
+	  This feature goes to next minor (2.1?).
+	  Nobody may use this feature and there is no compatibility issue.
+
+	* proc.c (rb_method_entry_arity): ditto.
+
+	* vm_eval.c, vm_insnhelper.c, vm_method.c: ditto.
+
+Tue Dec 18 04:58:22 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_trace.c (fill_id_and_klass): TracePoint#defined_class returns
+	  singleton class. `set_trace_func' passed attached class (which is
+	  attached/modified by singleton class) by 6th block parameter if it
+	  is singleton class. Previous behavior follows this spec.
+	  However, this method named `defined_class' should return singleton
+	  class directly because singleton methods are defined in singleton
+	  class. There are no compatible issue because TracePoint is introduced
+	  after 2.0.
+	  But compatibility with `set_trace_func' is broken. This means that
+	  you can not replace all `set_trace_func' code with TracePoint
+	  without consideration of this behavior.
+	  [Bug #7554]
+
+	* test/ruby/test_settracefunc.rb: change a test to catch up

+
+	* eval.c (rb_using_refinement): skip the above superclass (the
+	  refined class) when creating iclasses for refinements.  Otherwise,
+	  `using Refinement1; using Refinement2' creates iclasses:
+	  <Refinement2> -> <RefinedClass> -> <Refinement1> -> RefinedClass,

+	  searched before Refinement1.  The correct iclasses should be
+	  <Refinement2> -> <Refinement1> -> RefinedClass.
+
+	* vm_insnhelper.c (vm_search_normal_superclass): if klass is an
+	  iclass for a refinement, use the refinement's superclass instead
+	  of the iclass's superclass.  Otherwise, multiple refinements are
+	  searched by super.  For example, if a refinement Refinement2
+	  includes a module M (i.e., Refinement2 -> <M> -> RefinedClass,
+	  and if refinements iclasses are <Refinement2> -> <M>' ->
+	  <Refinement1> -> RefinedClass, then super in <Refinement2> should
+	  use Refinement2's superclass <M> instead of <Refinement2>'s
+	  superclass <M>'.
+
+	* vm_insnhelper.c (vm_search_super_method): do not raise a
+	  NotImplementError if current_defined_class is a module included
+	  into a refinement.  Because of the change of

+
+Thu Dec  6 18:23:05 2012  Shugo Maeda  <shugo@ruby-lang.org>
+
+	* revised r37993 to avoid SEGV/ILL in tests.  In r37993, a method
+	  entry with VM_METHOD_TYPE_REFINED holds only the original method
+	  definition, so ci->me is set to a method entry allocated in the
+	  stack, and it causes SEGV/ILL.  In this commit, a method entry
+	  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
+	  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
+	  avoid GC for iclasses created by copy_refinement_iclass().
+
+	* vm_method.c (rb_method_entry_make): add a method entry with
+	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
+	  the target module is a refinement.  When a method entry with
+	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
+	  the same name is searched in refinements.  If such a method is
+	  found, the method is invoked.  Otherwise, the original method in
+	  the refined class (rb_method_definition_t::body.orig_me) is
+	  invoked.  This change is made to simplify the normal method lookup
+	  and to improve the performance of normal method calls.
+
+	* vm_method.c (EXPR1, search_method, rb_method_entry),
+	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
+	  refinements for method lookup.
+
+	* vm_insnhelper.c (vm_call_method): search methods in refinements if
+	  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
+	  super (i.e., ci->call == vm_call_super_method), skip the same
+	  method entry as the current method to avoid infinite call of the
+	  same method.
+
+	* class.c (include_modules_at): add a refined method entry for each
+	  method defined in a module included in a refinement.
+
+	* class.c (rb_prepend_module): set an empty table to
+	  RCLASS_M_TBL(klass) to add refined method entries, because
+	  refinements should have priority over prepended modules.
+
+	* proc.c (mnew): use rb_method_entry_with_refinements() to get
+	  a refined method.
+
+	* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
+	  copy_refinement_iclass().
+
+	* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
+
+	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
+	  the test because it should pass successfully.
+
+	* test/ruby/test_refinement.rb (test_redefine_refined_method): new
+	  test for the case a refined method is redefined.

+
+	* vm_method.c (rb_method_entry_make): add a method entry with
+	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
+	  the target module is a refinement.  When a method entry with
+	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
+	  the same name is searched in refinements.  If such a method is
+	  found, the method is invoked.  Otherwise, the original method in
+	  the refined class (rb_method_definition_t::body.orig_def) is
+	  invoked.  This change is made to simplify the normal method lookup
+	  and to improve the performance of normal method calls.
+
+	* vm_method.c (EXPR1, search_method, rb_method_entry),
+	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
+	  refinements for method lookup.

+	  super (i.e., ci->call == vm_call_super_method), skip the same
+	  method entry as the current method to avoid infinite call of the
+	  same method.
+
+	* class.c (include_modules_at): add a refined method entry for each
+	  method defined in a module included in a refinement.
+
+	* class.c (rb_prepend_module): set an empty table to
+	  RCLASS_M_TBL(klass) to add refined method entries, because
+	  refinements should have priority over prepended modules.
+
+	* proc.c (mnew): use rb_method_entry_with_refinements() to get
+	  a refined method.
+
+	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
+	  the test because it should pass successfully.
+
+	* test/ruby/test_refinement.rb (test_redefine_refined_method): new

+	* lib/rubygems.rb (Gem.load_yaml): return if Kernel#gem is not defined

+
+	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):
+	  add a new optimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
+	  This optimization makes all cfunc method calls `frameless', which
+	  is faster than ordinal cfunc method call.
+	  If `frame' is needed (for example, it calls another method with
+	  `rb_funcall()'), then build a frame. In other words, this
+	  optimization delays frame building.
+	  However, to delay the frame building, we need additional overheads:
+	    (1) Store the last call information.
+	    (2) Check the delayed frame building before the frame is needed.
+	    (3) Overhead to build a delayed frame.
+	  rb_thread_t::passed_ci is storage of delayed cfunc call information.
+	  (1) is lightweight because it is only 1 assignment to `passed_ci'.
+	  To achieve (2), we modify GET_THREAD() to check `passed_ci' every
+	  time. It causes 10% overhead on my environment.
+	  This optimization only works for cfunc methods which do not need
+	  their `frame'.
+	  After evaluation on my environment, this optimization does not
+	  effective every time. Because of this evaluation results, this
+	  optimization is disabled at default.
+
+	* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour
+	  of VM internals. I will extend this feature.
+
+	* vm_method.c, method.h: change parameters of the `invoker' function.

+
+Wed Oct 17 08:32:46 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* compile.c (compile_dstr_fragments): use `putobject' instead of
+	  `putstring' for all of strings used by NODE_DSTR because
+	  ruby users can not grab this string.
+	  For example, the string object of "baz" in "foo#{bar}baz"
+	  is located by `putobject' (users can not touch "baz" object
+	  directly). This change reduces GC pressure.
+	  This improvement is suggested by Aaron Patterson.

+Wed Oct 17 05:05:07 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_invoke_block): vm_caller_setup_args() can skip

+
+Wed Oct 17 01:53:47 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_getivar, vm_setivar): support index inline cache
+	  with rb_call_info_t to speedup `attr' getter and setter.
+	  Cached index is stored in rb_call_info_t::aux::index.
+	  `index' == 0 means not cached. `index' > 0 means cached and cached
+	  index is `index - 1'.
+
+	* insns.def ((get|set)instancevariable): use new wrapper functions
+	  vm_(get|set)instancevariable() defined in vm_insnhelper.c.
+
+	* vm_core.h (rb_call_info_t::aux): introduce new union data because
+	  opt_pc can share with index.

+	  if two or more executables are given.
+
+Tue Oct 16 21:59:01 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* benchmark/driver.rb: some refactoring.
+	  (1) Remove `average differential'.
+	      In this benchmark driver, We should not care about `average'.
+	      We use fastest score because this score should not include
+	      any disturbances (affections of background process, etc).
+	      If you care about timing affect, I recommend `median'
+	      score with more than 5 examinations rather than simple
+	      `average' score (`average' score was affected by error scores).
+	  (2) Show log file name.

+
+Tue Oct 16 06:29:18 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_call_method): disable CI_SET_FASTPATH() if
+	  this method call needs splat argument because cached functions
+	  (vm_call_attrset, vm_call_ivar, vm_call_cfunc_fast_(unary|binary))
+	  do not check an arity.
+
+	* bootstraptest/test_method.rb: add a test to check an above issue.
+
+Tue Oct 16 06:15:44 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* method.h: introduce new method type VM_METHOD_TYPE_CFUNC_FAST.
+	  This method is similar to VM_METHOD_TYPE_CFUNC methods, but
+	  called cfunc without building new frame (does not push new control
+	  frame). If error is occurred in cfunc, the backtrace only shows
+	  caller frame and upper.
+	  This kind of methods can be added by rb_define_method_fast().
+	  This feature is similar to specialized instructions (opt_plus, etc),
+	  but more flexible (but a bit slower).
+
+	* class.c (rb_define_method_fast): added.
+	  Maybe it will be renamed soon.
+
+	* vm_insnhelper.c (vm_call_method): support method type
+	  VM_METHOD_TYPE_CFUNC_FAST.
+
+	* proc.c (rb_method_entry_arity): catch up new method type.
+
+	* vm_method.c (rb_add_method_cfunc_fast): added.
+
+Tue Oct 16 02:32:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h (CI_SET_FASTPATH): add new parameter `enabled'.
+	  If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
+	  And add new configuration option OPT_CALL_FASTPATH. If this macro
+	  was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
+
+	* vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
+	  of CI_SET_FASTPATH if this method is protected.
+
+Tue Oct 16 02:17:35 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_core.h (VM_CALL_*): rename VM_CALL_*_BIT
+	  to VM_CALL_* (remove `_BIT' suffix).
+	  Add comments on each macros.
+	  Remove unused macro VM_CALL_TAILRECURSION_BIT.

+	  rewrite file assertions.
+
+Mon Oct 15 09:41:17 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (VM_CALLEE_SETUP_ARG): skip CI_SET_FASTPATH() if
+	  it was called from vm_yield_setup_args().
+
+Mon Oct 15 05:20:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h CI_SET_FASTPATH: introduce new macro
+	  `CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'.
+	  `func' (ci->call) is called at the last of `send'
+	  (and `invokesuper') instruction.
+	  `CI_SET_FASTPATH' does not set `ci->call' when the method
+	  (stored in `ci->me') is `protected'.
+
+	* vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'.
+	  After several checking (visibility, argc checking), the result of
+	  checking can be reused until re-definition of this method
+	  with inline method cache.
+
+	  Note that this optimization is now experimental.
+	  If you find any problem about it, please tell us.
+
+Mon Oct 15 04:51:55 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c: refactoring.
+	  - move all `call' related functions to the last of file.
+	  - make functions for respective method types in vm_call_method().
+	    (all functions have same function parameters)
+
+	* vm_core.h: add `opt_pc' field in `rb_call_info_t'
+	  as temporal variable.

+
+Mon Oct 15 03:51:46 2012  Koichi Sasada  <ko1@atdot.net>
+

+
+Mon Oct 15 02:51:16 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (vm_call0_body): add new function.
+	  `vm_call0()' makes call_info struct and calls `vm_call0_body()'
+	  with this struct. In near future, `vm_call0()' will be removed
+	  because all of `vm_call0()' users setup call_info struct by itself.
+
+Mon Oct 15 01:38:06 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* insns.def (send, invokesuper, invokeblock, opt_*), vm_core.h:
+	  use only a `ci' (rb_call_info_t) parameter instead of using
+	  parameters such as `op_id', 'op_argc', `blockiseq' and flag.
+	  These information are stored in rb_call_info_t at the compile
+	  time.
+	  This technique simplifies parameter passing at related
+	  function calls (~10% speedups for simple method invocation at
+	  my machine).
+	  `rb_call_info_t' also has new function pointer variable `call'.
+	  This `call' variable enables to customize method (block)
+	  invocation process for each place. However, it always call
+	  `vm_call_general()' at this changes.
+	  `rb_call_info_t' also has temporary variables for method
+	  (block) invocation.
+
+	* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP
+	  VM_CALL macro.  This flag indicates that this call can skip
+	  caller_setup (block arg and splat arg).
+
+	* compile.c: catch up above changes.
+
+	* iseq.c: catch up above changes (especially for TS_CALLINFO).
+
+	* tool/instruction.rb: catch up above changes.
+
+	* vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions
+	  parameters are changed.

+	* vm_trace.c, vm_core.h: simplify tracing mechanism.
+
+	  (1) add rb_hook_list_t data structure which includes
+	      hooks, events (flag) and `need_clean' flag.
+	      If the last flag is true, then clean the hooks list.
+	      In other words, deleted hooks are contained by `hooks'.
+	      Cleanup process should run before traversing the list.
+	  (2) Change check mechanism
+	      See EXEC_EVENT_HOOK() in vm_core.h.
+	  (3) Add `raw' hooks APIs
+	      Normal hooks are guarded from exception by rb_protect().
+	      However, this protection is overhead for too simple
+	      functions which never cause exceptions.  `raw' hooks
+	      are executed without protection and faster.
+	      Now, we only provide registration APIs.  All `raw'
+	      hooks are kicked under protection (same as normal hooks).
+
+	* include/ruby/ruby.h: remove internal data definition and
+	  macros.
+
+	* internal.h (ruby_suppress_tracing), vm_trace.c: rename
+	  ruby_suppress_tracing() to rb_suppress_tracing()

+	* vm.c (mark_event_hooks): move definition to vm_trace.c.

+	  with ruby_vm_event_flags.

+
+	* iseq.c, vm_eval.c: set th->base_block properly.
+	  th->base_block is information for (a) parsing, (b) compiling
+	  and (c) setting up the frame to execute the program passed by
+	  `eval' method.  For example, (1) parser need to know up-level
+	  variables to detect it is variable or method without paren.
+	  Befor (a), (b) and (c), VM set th->base_block by passed bindng
+	  (or previous frame information).  After execute (a), (b) and (c),
+	  VM should clear th->base_block.  However, if (a), (b) or (c)
+	  raises an exception, then th->base_block is not cleared.
+	  Problem is that the uncleared value th->balo_block is used for
+	  irrelevant iseq compilation.  It causes SEGV or critical error.
+	  I tried to solve this problem: to clear them before exception,
+	  but finally I found out that it is difficult to do it (Ruby
+	  program can be run in many places).
+	  Because of this background, I set th->base_block before
+	  compiling iseq and restore it after compiling.
+	  Basically, th->base_block is dirty hack (similar to global
+	  variable) and this patch is also dirty.

+
+	* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).
+	  Before this commit:
+	    `finish frame' was place holder which indicates that VM loop
+	    needs to return function.
+	    If a C method calls a Ruby methods (a method written by Ruby),
+	    then VM loop will be (re-)invoked.  When the Ruby method returns,
+	    then also VM loop should be escaped.  `finish frame' has only
+	    one instruction `finish', which returns VM loop function.
+	    VM loop function executes `finish' instruction, then VM loop
+	    function returns itself.
+	    With such mechanism, `leave' instruction (which returns one
+	    frame from current scope) doesn't need to check that this `leave'
+	    should also return from VM loop function.
+	    Strictly, one branch can be removed from `leave' instruction.
+	  Consideration:
+	    However, pushing the `finish frame' needs costs because
+	    it needs several memory accesses.  The number of pushing
+	    `finish frame' is greater than I had assumed.  Of course,
+	    pushing `finish frame' consumes additional control frame.
+	    Moreover, recent processors has good branch prediction,
+	    with which we can ignore such trivial checking.
+	  After this commit:
+	    Finally, I decide to remove `finish frame' and `finish'
+	    instruction.  Some parts of VM depend on `finish frame',
+	    so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
+	    If this frame should escape from VM function loop, then
+	    the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
+	    `leave' instruction checks this flag every time.
+	    I measured performance on it.  However on my environments,
+	    it improves some benchmarks and slows some benchmarks down.
+	    Maybe it is because of C compiler optimization parameters.
+	    I'll re-visit here if this cause problems.
+
+	* insns.def (leave, finish): remove finish instruction.

+
+	* vm_core.h: remove lfp (local frame pointer) and rename
+	  dfp (dynamic frame pointer) to ep (environment pointer).
+	  This change make VM `normal' (similar to other interpreters).
+	  Before this commit:
+	    Each frame has two env pointers lfp and dfp.  lfp points
+	    local environment which is method/class/toplevel frame.
+	    lfp[0] is block pointer.
+	    dfp is block local frame. dfp[0] points previous (parent)
+	    environment pointer.
+	    lfp == dfp when frame is method/class/toplevel.
+	    You can get lfp from dfp by traversing previous environment
+	    pointers.
+	  After this commit:
+	    Each frame has only `ep' to point respective environment.
+	    If there is parent environment, then ep[0] points parent
+	    environment (as dfp).  If there are no more environment,
+	    then ep[0] points block pointer (as lfp).  We call such ep
+	    as `LEP' (local EP).  We add some macros to get LEP and to
+	    detect LEP or not.
+	    In short, we replace dfp and lfp with ep and LEP.
+	  rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
+	  and member `ep' is added.
+	  rename rb_thread_t's member `local_lfp' and `local_svar' to
+	  `root_lep' and `root_svar'.
+	  (VM_EP_PREV_EP(ep)): get previous environment pointer.  This macro

+Sat May 26 13:40:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c (RubyVM::FrameInfo): add a class to access each frame
+	  information.  You don't need to parse strings from caller().
+	  FrameInfo has the following methods:
+	    FrameInfo#name: method name, class name, etc with decorations.
+	    FrameInfo#basename: name without decorations.
+	    FrameInfo#line_no: line number.
+	    FrameInfo#filename: file name.
+	    FrameInfo#filepath: full filepath.
+	    FrameInfo#iseq: iseq if it is iseq frame (defined by ruby script)
+	    FrameInfo#to_s: return caller() method style string.
+	  RubyVM::FrameInfo.caller(n, lev) returns array of FrameInfo objects.
+	  The name "RubyVM::FrameInfo.caller" is long and ambiguous (it is
+	  confusing with Kernel::caller() method), we need to change the name
+	  before Ruby 2.0 release. Good names or comments are welcome.
+
+	* test/ruby/test_backtrace.rb: add a test for above change.

+
+	* vm.c (rb_backtrace_to_str_ary): fix to use backtrace_object().
+	  This change improve performance of caller(lev, n).
+
+	* benchmark/bm_vm3_backtrace.rb: added to check above improvement.
+	  FYI: measurement on my laptop, 1.9.3p229 needs 5.125 sec,

+
+	* ext/openssl/ossl_ssl.c: Allow disabling client-side renegotiation.
+	* test/openssl/test_ssl.rb: Simple tests for this.
+
+	  Client-side renegotiation is still considered problematic, even
+	  when used in the context of secure renegotiation (RI, RFC 5746).
+	  The changes allow users to either completely disable client
+	  renegotiation on the server, or to specify a maximum number of
+	  handshakes allowed in total. The number of total handshakes is
+	  counted in a callback set as SSL_set_info_callback. If the
+	  maximum number of handshakes is exceeded an error will be raised
+	  We do not support renegotiation in the OpenSSL extension, therefore
+	  this feature can only be tested externally.
+	  The feature is opt-in, the default setting will be to allow
+	  unlimited client renegotiation, as was the case before.
+
+Fri May 25 23:38:58 2012  Martin Bosslet  <Martin.Bosslet@googlemail.com>
+
+	* test/openssl/test_ssl.rb: Clarify the intention of errors to be
+	  expected. Two errors are possible when connection is refused due

+	  OpenSSL version in use.

+
+Fri May 25 19:51:36 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (rb_f_caller): caller() method accepts second optional
+	  argument `n' which specify how many frames should return.
+	  For example, `caller(0, 1)' returns only one frame information
+	  which calls caller() method.  If there are less than n frame
+	  information, then all frame information are returned.  If n is 0,
+	  then always return [].
+	  This fix is part of [ruby-dev:42345] [Ruby 1.9-Feature#3917].
+	  However, performance and features are not enough.
+	  RDoc is also not available.
+
+	* test/ruby/test_backtrace.rb: add a test for above.

+
+Fri May 25 10:52:52 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: refactoring backtrace related functions.
+	  (1) unify similar functions (rb_backtrace_each() and
+	      backtrace_object()).  backtrace_each() is a unified function.
+	      variation:
+	      a) backtrace_object(): create backtrace object.
+	      b) vm_backtrace_str_ary(): create bt as an array of string.
+	      c) vm_backtrace_print(): print backtrace to specified file.
+	      d) rb_backtrace_print_as_bugreport(): print backtrace on
+	                                            bugreport style.
+	  (2) remove rb_backtrace_each().  Use backtrace_each() instead.
+	  (3) change the type of lev parameter to size_t.
+	      a) lev == 0 means current frame (exception, etc use it).
+	      b) lev == 1 means upper frame (caller(0) use it).
+
+	* vm_core.h, vm_dump.c, vm_eval.c: ditto.
+
+	* vm.c (backtrace_object(), vm_backtrace_str_ary()): fix to return a
+	  correct size of caller(lev) array.
+	  Let n be a "caller(0).size" then ln as caller(lev).size should be
+	  (n - lev).  However, the previous implementation returns a wrong
+	  size array (ln > n - lev).  [ruby-dev:45673]
+
+	* test/ruby/test_backtrace.rb: add tests for backtrace.

+	* error.c, eval_error.c: change for above.
+
+Thu May 24 14:30:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: add RubyVM::Backtrace object (btobj).
+	  Backtrace information contains an array consists of location
+	  information for each frames by string.
+	  RubyVM::Backtrace object is lightweight backtrace information,
+	  which contains complete information to generate traditional style
+	  backtrace (an array of strings) with faster generation.
+	  If someone accesses to backtrace information via
+	  Exception#backtrace, then convert a RubyVM::Backtrace object to
+	  traditional style backtrace.
+	  This change causes incompatibility on marshal dumped binary
+	  of Exception.  If you have any trouble on it, please tell us
+	  before Ruby 2.0 release.
+	  Note that RubyVM::Backtrace object should not expose Ruby level.
+
+	* error.c, eval.c, vm_eval.c: ditto.
+
+	* internal.h: ditto.
+
+	* eval_error.c: fix to skip "set_backtrace" method invocation in
+	  creating an exception object if it call a normal set_backtrace
+	  method (defined by core).
+
+	* test/ruby/test_settracefunc.rb: fix for above change.
+
+	* vm_method.c (rb_method_defined_by): added.  This function
+	  checks that the given object responds with the given method
+	  by the given cfunc.
+
+	* benchmark/bm_vm2_raise1.rb, benchmark/bm_vm2_raise2.rb:
+	  add to measure exception creation speed. raise1 create
+	  exception objects from shallow stack frame.  raise2 create
+	  exception objects from deep stack frame.

+
+	  In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
+	  TLS-CBC-IV vulnerability described at
+	  http://www.openssl.org/~bodo/tls-cbc.txt
+	  It's known issue of TLSv1/SSLv3 but it attracts lots of attention
+	  these days as BEAST attack. (CVE-2011-3389)
+
+	  Until now ossl sets OP_ALL at SSLContext allocation and call
+	  SSL_CTX_set_options at connection.  SSL_CTX_set_options updates the
+	  value by using |= so bits set by OP_ALL cannot be unset afterwards.
+
+	  This commit changes to call SSL_CTX_set_options only 1 time for each
+	  SSLContext. It sets the specified value if SSLContext#options= are
+	  called and sets OP_ALL if not.
+
+	  To help users to unset bits in OP_ALL, this commit also adds several
+	  constant to SSL such as
+	  OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.  These constants were
+	  not exposed in Ruby because there's no way to unset bits in OP_ALL
+	  before.
+
+	  Following is an example to enable 0/n split for BEAST prevention.
+
+	    ctx.options = OP_ALL & ~OP_DONT_INSERT_EMPTY_FRAGMENTS
+
+	* test/openssl/test_ssl.rb: Test above option exists.

+
+Fri Aug 26 19:12:08 2011  Hiroshi Nakamura  <nahi@ruby-lang.org>
+
+	* variable.c: Make autoload thread-safe. See #921.
+
+	  What's the problem?
+	    autoload is thread unsafe. When we define a constant to be
+	    autoloaded, we expect the constant construction is invariant. But
+	    current autoload implementation allows other threads to access the
+	    constant while the first thread is loading a file.
+
+	  What's happening inside?
+	    The current implementation uses Qundef as a marker of autoload in
+	    Constant table. Once the first thread find Qundef as a value at
+	    constant lookup, it starts loading a defined feature. Generally a
+	    loaded file overrides the Qundef in Constant table by module/class
+	    declaration at very beginning lines of the file, so other threads
+	    can see the new Module/Class object before feature loading is
+	    finished. It breaks invariant construction.
+
+	  How to solve?
+	    To ensure invariant constant construction, we need to override
+	    Qundef with defined Object after the feature loading. For keeping
+	    Qundef in Constant table, I expanded autoload_data struct in
+	    Module to have a slot for keeping the defined object while feature
+	    loading. And changed Module's constant lookup/update logic a
+	    little so that the slot is only visible from the thread which
+	    invokes feature loading. (== the first thread which accessed the
+	    autoload constant)
+
+	  Evaluation?
+	    All test passes (bootstrap test, test-all and RubySpec) and added
+	    8 tests for threading behavior. Extra logics are executed only
+	    when Qundef is found, so no perf drop should happen except
+	    autoloading.
+
+	* variable.c (rb_autoload): Prepare new autoload_data struct.
+
+	* variable.c (rb_autoload_load): Load feature and update Constant

+	* variable.c (rb_const_defined_0): Ditto.
+
+	* variable.c (rb_const_set): When the specified constant is under
+	  autoloading, it sets the object only for the thread which starts
+	  autoloading. Otherwise, simply overrides Qundef with constant
+	  override warning.

+	  This problem is caused by changing dfp (dynamic env pointer)

+	  the dfp can be moved because VM copies env from VM stack to
+	  the heap.  At this copying, dfp was also changed.  To solve this

+
+	* internal.h: do not use ruby_sized_xrealloc() and ruby_sized_xfree()

+
+	  We don't need these function if malloc_usable_size() is available.

+
+	* gc.c: change terminology OLDSPACE -> OLDMALLOC.
+	  (oldspace -> oldmalloc for variable names)
+
+	  OLDSPACE is confusing because it is not includes slots.
+	  To more clearly, rename such as (oldspace_limit -> oldmalloc_limit).

+
+	* gc.c: change RGENGC_CHECK_MODE (>= 2) logic.
+	  Basically, make an object graph of all of living objects before and
+	  after marking and check status.
+
+	  [Before marking: check WB sanity]
+	  If there is a non-old object `obj' pointed from old object
+	  (`parent') then `parent' or `obj' should be remembered.
+
+	  [After marking: check marking miss]
+	  Traversible objects with the object graph should be marked.
+	  (However, this alert about objects pointed by machine context
+	   can be false positive. We only display alert.)
+
+	  [Implementation memo]
+	  objspace_allrefs() creates an object graph.
+	  The object graph is represented by st_table, key is object (VALUE)
+	  and value is referring objects. Referring objects are stored by
+	  "struct reflist".
+
+	* gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init.
+	  This pre-allocation causes failure on is_mark_stack_empty()
+	  without any pushing.

+
+	* gc.c: add support to estimate increase of oldspace memory usage.
+	  This is another approach to solve an issue discussed at r43530.
+	  This feature is disabled as default.
+
+	  This feature measures an increment of memory consumption by oldgen
+	  objects. It measures memory consumption for each objects when
+	  the object is promoted. However, measurement of memory consumption
+	  is not accurate now. So that this measurement is `estimation'.
+
+	  To implement this feature, move memsize_of() function from
+	  ext/objspace/objspace.c and expose rb_obj_memsize_of().
+
+	  Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
+	  measure memory size, so that we ignores T_DATA objects now.
+	  For example, some functions skip NULL check for pointer.
+
+	  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
+	  and turned off as default.
+
+	  We need to compare 3gen GC and this feature carefully.
+	  (it is possible to enable both feature)
+	  We need a help to compare them.
+
+	* internal.h: expose rb_obj_memsize_of().
+
+	* ext/objspace/objspace.c: use rb_obj_memsize_of() function.

+
+	* gc.c: add 3gen GC patch, but disabled as default.
+
+	  RGenGC is designed as 2 generational GC, young and old generation.
+	  Young objects will be promoted to old objects after one GC.
+	  Old objects are not collect until major (full) GC.
+
+	  The issue of this approach is some objects can promote as old
+	  objects accidentally and not freed until major GC.
+	  Major GC is not frequently so short-lived but accidentally becoming
+	  old objects are not freed.
+
+	  For example, the program "loop{Array.new(1_000_000)}" consumes huge
+	  memories because short lived objects (an array which has 1M
+	  elements) are promoted while GC and they are not freed before major
+	  GC.
+
+	  To solve this problem, generational GC with more generations
+	  technique is known. This patch implements three generations gen GC.
+
+	  At first, newly created objects are "Infant" objects.
+	  After surviving one GC, "Infant" objects are promoted to "Young"
+	  objects.
+	  "Young" objects are promoted to "Old" objects after surviving
+	  next GC.
+	  "Infant" and "Young" objects are collected if it is not marked
+	  while minor GC. So that this technique solves this problem.
+
+	  Representation of generations:
+	  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]
+	  * Young :  FL_PROMOTED and !oldgen_bitmap [10]
+	  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
+
+	  The macro "RGENGC_THREEGEN" enables/disables this feature, and
+	  turned off as default because there are several problems.
+	  (1) Failed sometimes (Heisenbugs).
+	  (2) Performance down.
+	      Especially on write barriers. We need to detect Young or Old
+	      object by oldgen_bitmap. It is slower than checking flags.
+
+	  To evaluate this feature on more applications, I commit this patch.
+	  Reports are very welcome.
+
+	  This patch includes some refactoring (renaming names, etc).
+
+	* include/ruby/ruby.h: catch up 3gen GC.

+	  Tomb heap is where zombie objects and ghost (freed slot) lived in.
+	  Separate from other heaps (now there is only eden heap) at sweeping
+	  helps freeing pages more efficiently.
+	  Before this patch, even if there is an empty page at former phase
+	  of sweeping, we can't free it.
+
+	  Algorithm:
+	    (1) Sweeping all pages in a heap and move empty pages from the
+	        heap to tomb_heap.
+	    (2) Check all existing pages and free a page
+	        if all slots of this page are empty and
+	           there is enough empty slots (checking by swept_num)
+
+	  To introduce this patch, there are several tuning of GC parameters.

+
+	  * Add ruby-electric-mode-hook.
+
+	  * Use a remap in binding ruby-electric-delete-backward-char.
+
+	  * Totally revamp electric keywords and then introduce electric
+	    return.  Modifier keywords are now properly detected making
+	    use of ruby-mode's indentation level calculator, and

+	  * block-mid keywords (then, else, elsif, when, rescue and

+
+	  * Add standardized comments for ELPA integration.
+
+	  * Fix interaction with smartparens-mode by disabling its end
+	    keyword completion, since ruby-electric has become more clever
+	    at it.
+
+	  * The custom variable `ruby-electric-keywords` is changed to
+	    `ruby-electric-keywords-alist`, allowing user to fine-grained

+
+	* gc.c: simplify threshold of GC caused by malloc_increase.
+	  Now, malloc_limit is increased/decreased by mysterious logic.
+	  This fix simplify malloc_limit increase/decrease logic such as:
+	    if (malloc_increase > malloc_limit) /* so many malloc */
+	      malloc_limit += malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1);
+	    else
+	      malloc_limit -= malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1)/4;
+	  Default value of GC_MALLOC_LIMIT_FACTOR is 1.8.
+	  malloc_limit is bounded by GC_MALLOC_LIMIT_MAX (256MB by default).
+	  This logic runs at gc_before_sweep(). So there are no effect from
+	  caused by lazy sweep. And we can remove malloc_increase2.
+
+	* gc.c (HEAP_MIN_SLOTS, FREE_MIN, HEAP_GROWTH_FACTOR): rename to
+	  GC_HEAP_MIN_SLOTS, GC_FREE_MIN, GC_HEAP_GROWTH_FACTOR respectively.
+	  Check them by `#ifndef' so you can specify these values outside gc.c.
+
+	* gc.c (ruby_gc_params_t): add initial_malloc_limit_factor and
+	  initial_malloc_limit_max.
+
+	* gc.c (vm_malloc_prepare, vm_xrealloc): use vm_malloc_increase to
+	  add and check malloc_increase.

+
+	* variable.c (rb_const_set): fix WB miss.
+
+	  WBs had located before creating reference between a klass
+	  and constant value. It causes GC bug.
+
+	    # pseudo code:
+	    WB(klass, value); # WB and remember klass
+	    st_insert(klass->const_table, const_id, value);
+
+	  `st_insert()' can cause GC before inserting `value' and
+	  forget `klass' from the remember set. After that, relationship
+	  between `klass' and `value' are created with constant table.
+	  Now, `value' can be young (shady) object and `klass' can be old
+	  object, without remembering `klass' object.
+	  At the next GC, old `klass' object will be skipped and
+	  young (shady) `value' will be miss-collected. -> GC bug
+
+	  Lesson: The place of a WB is important.

+
+	* ext/objspace/object_tracing.c: add two new methods:
+	  * ObjectSpace.allocation_class_path(o)
+	  * ObjectSpace.allocation_method_id(o)
+	  They are not useful for Object.new because they are always
+	  "Class" and :new.

+
+Mon May 27 18:57:28 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.
+	  Read the following test to know HOWTO.
+	  This feature is a sample of RUBY_INTERNAL_EVENT.
+
+	* test/objspace/test_objspace.rb: add a test.

+
+	* vm_trace.c (rb_postponed_job_flush, rb_postponed_job_register): use

+
+Mon May 27 09:24:03 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* test/-ext-/postponed_job/test_postponed_job.rb: fix typo and class name.
+
+Mon May 27 09:05:17 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.
+	  * RUBY_INTERNAL_EVENT_NEWOBJ: object created.
+	  * RUBY_INTERNAL_EVENT_FREE: object freed.
+	  * RUBY_INTERNAL_EVENT_GC_START: GC started.
+	  And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
+
+	  Internal events can not invoke any Ruby program because the tracing
+	  timing may be critical (under huge restriction).
+	  These events can be hooked only by C-extensions.
+	  We recommend to use rb_postponed_job_register() API to call Ruby
+	  program safely.
+
+	  This change is mostly written by Aman Gupta (tmm1).

+
+Mon May 27 06:22:41 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.
+	  Postponed jobs are registered with this API. Registered jobs
+	  are invoked at `ruby-running-safe-point' as soon as possible.
+	  This timing is completely same as finalizer timing.
+
+	  There are two APIs:
+	  * rb_postponed_job_register(flags, func, data): register a
+	    postponed job with data. flags are reserved.
+	  * rb_postponed_job_register_one(flags, func, data): same as
+	    `rb_postponed_job_register', but only one `func' job is
+	    registered (skip if `func' is already registered).

+	  This change is mostly written by Aman Gupta (tmm1).
+	  https://bugs.ruby-lang.org/issues/8107#note-15

+
+	* gc.c (gc_stat): collect shade_operation_count,

+
+Mon May 27 01:15:22 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* hash.c (rb_hash_tbl_raw), internal.h: added.

+
+	* proc.c (rb_method_entry_min_max_arity): fix missing break in switch.
+	  This was introduced in r38236, which is not intentional apparently.
+	  This has caused no actual harm because VM_METHOD_TYPE_OPTIMIZED is
+	  not used except for OPTIMIZED_METHOD_TYPE_SEND, but may do in

+	  This function reveal internal (hidden) object by rb_obj_hide().
+	  Note that do not change class before and after hiding.
+	  Only permitted example is:
+	    klass = RBASIC_CLASS(obj);
+	    rb_obj_hide(obj);
+	    ....
+	    rb_obj_reveal(obj, klass);
+
+	  TODO: API design. rb_obj_reveal() should be replaced with others.
+
+	  TODO: modify constified variables using cast may be harmful for
+	        compiler's analysis and optimization.
+	        Any idea to prohibit inserting RBasic::klass directly?
+	        If rename RBasic::klass and force to use RBASIC_CLASS(obj),
+	        then all codes such as `RBASIC(obj)->klass' will be
+	        compilation error. Is it acceptable? (We have similar
+	        experience at Ruby 1.9,
+	        for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
+
+	* internal.h: add some macros.

+	    object.

+
+	  Before this patch, gc_marks_step() marks (white -> grey) fixed
+	  number objects. However, this strategy does not fit practical
+	  cases, for example too slow to make progress.
+
+	  This patch changes this strategy how many objects the
+	  gc_marks_step() should handle.
+
+	  We can estimate how many times gc_marks_step() is called during
+	  this major marking (== C) with the free slot number in pooled
+	  pages. We also can estimate the living object number (== L)
+	  using last marked_slots value. We can solve this problem (how
+	  many objects should be process in gc_marks_step()) by L/C.
+
+	* gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_slots and
+	  step_slots.

+	  [Feature #10440] (Details are described in this ticket)
+
+	  Most of complex part is moved to vm_args.c.
+
+	  Now, ISeq#to_a does not catch up new instruction format.

+	* insns.def (opt_send_simple): removed and add new instruction
+	  "opt_send_without_block".

+	* parse.y (new_args_tail_gen): reorder variables.
+	  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
+	  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
+	  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
+	  (locate a block variable at last)

+	    (ruby process)
+	    (... repeat (5), (6))
+	  (7) GC_ENTER
+	      (finish lazy sweep)
+	    - (8) GC_END_SWEEP
+	  (9) GC_EXIT
+
+	  2nd example (incremental major marking):
+	  (1) GC_ENTER
+	  - (2) GC_START (minor GC)
+	    (start incremental marking)
+	  (3) GC_EXIT
+	    (ruby process)
+	  (4) GC_ENTER
+	    (incremental marking)
+	  (5) GC_EXIT
+	     (ruby process)
+	     (... repeat (4), (5))
+	  (6) GC_ENTER
+	    (finish incremental marking)
+	  - (7) GC_END_MARK
+	    (start lazy sweep)
+	  (8) GC_EXIT
+	    (ruby process)
+	  (9) GC_ENTER
+	    (lazy sweep)
+	  (10) GC_EXIT
+	    (ruby process)
+	    (... repeat (9), (10))
+	  (11) GC_ENTER
+	    (finish lazy marking)
+	  - (12) GC_STOP_SWEEP
+	  (13) GC_EXIT

+	  This change also introduces the following changes.
+
+	  * Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
+	    Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
+	    RBasic::flags (2 bit). Age == 3 objects become old objects.
+	  * WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
+	  * LONG_LIVED bitmap to represent living objects while minor GCs
+	    It specifies (1) Old objects and (2) remembered shady objects.
+	  * Introduce rb_objspace_t::marked_objects which counts marked
+	    objects in current marking phase. marking count is needed to
+	    introduce incremental marking.
+	  * rename mark related function and sweep related function to
+	    gc_(marks|sweep)_(start|finish|step|rest|continue).
+	  * rename rgengc_report() to gc_report().

+	  never a serious bug.  But is annoying indeed to see warnings
+	  every time.  I added `=0` and all went healthy.
+
+	* configure.in: Also, I found that the problematic macro expansion
+	  only happens when we lack __typeof__ C extension, which shall
+	  not be the case of my compiler.  I added AC_C_TYPEOF to kick ass.

+	             write `buff' with WB(ary, &buff[i], obj)
+	             -> if `ary' and `shared' are old, then only `ary'
+	                will be remembered.
+	             -> traverse from `ary'. But `shared' is old, so
+	                that written `obj' is not marked.
+
+	  It cause WB miss so that shared arrays were WB-unprotected.
+	  (WB-unprotected objects are marked everytime if it is living)

+

+
+	* vm_insnhelper.c: introduce new call handler for simple ISeqs.
+
+	  vm_call_iseq_setup_normal_0start() is simple, however it has
+	  some loops/conditions depends on ISeq::param.size and
+	  ISeq::local_size (in vm_push_frame(), inlined into this function).
+
+	  There are many simple methods which has a few parameters and local
+	  variables. So that this patch introduces several special functions
+	  generated in vm_call_iseq_optimized.inc by
+	  tool/mk_call_iseq_optimized.rb.
+
+	  This script makes
+	    vm_call_iseq_setup_normal_0start_Xparams_Ylocals()
+	  where X is 0 to 3 and Y is 1 to 6 (as current setting).
+	  In this case, X * Y = 24 functions are created.
+
+	  These functions creates fast method dispatch by inlining
+	  vm_push_frame() with immediate params/locals sizes.
+
+	  On my laptop, we can have the following results.
+
+	  vm2_method*       1.083 (8.3% faster)
+	  vm2_poly_method*  0.961 (3.4% slower)
+
+	  It shows 8.3% faster for inner loop method dispatch (hit inline
+	  cache), but 3.4% slower when inline cache miss because we need
+	  to find a suitable call handler.
+
+	* common.mk: add a rule for vm_call_iseq_optimized.inc.
+
+	* tool/mk_call_iseq_optimized.rb: added.
+

+
+	  Trying to deq from a closed empty queue return nil
+	  if exception parameter equals to false (default).
+
+	  If exception parameter is truthy, it raises
+	  ClosedQueueError (< StopIteration).
+	  ClosedQueueError inherits StopIteration so that you can write:
+
+	    loop{ e = q.deq; (using e) }
+
+	  Trying to close a closed queue raises ClosedQueueError.
+
+	  Blocking threads to wait deq for Queue and SizedQueue will be
+	  restarted immediately by returning nil (exception=false) or
+	  raising a ClosedQueueError (exception=true).
+
+	  Blocking threads to wait enq for SizedQueue will be

+
+	* ext/thread/thread.c: move definitions of Queue, SizedQueue
+	  and ConditionalVariables to thread_tools.c. In other words,
+	  such classes are built-in.
+	  [Feature #8919]
+
+	  At first, I planned to embed only a Queue class.
+	  However, rubygems requires 'thread.rb' (rubygems are
+	  required at first, when launch MRI without --disable-gems).
+	  So most of people require 'thread.rb' as an embedded library.
+
+	  Now, ext/thread/thread.c is empty, only for a dummy for
+	  compatibility.
+
+	* thread.c: move a definition of Mutex class to thread_tools.c.
+
+	  And define Mutex class under Thread (so now Mutex is Thread::Mutex).
+	  Because other thread related classes are also defined under Thread.
+	  We remain ::Mutex as Thread::Mutex. Only an inspect result is changed.
+
+	* common.mk: add dependency from thread.o to thread_tools.c.
+
+Sat Aug 22 05:31:37 2015  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_opts.h, iseq.c, iseq.h: add compile option to force frozen
+	  string literals.
+	  [Feature #11473]
+
+	  This addition is not specification change, but to try frozen
+	  string literal world discussed on [Feature #11473].
+
+	  You can try frozen string literal world using this magical line:
+
+	    RubyVM::InstructionSequence.compile_option =
+	      {frozen_string_literal: true}
+
+	  Note that this is a global compilation option, so that you need to
+	  compile another script like that:
+
+	    p 'foo'.frozen? #=> false
+	    RubyVM::InstructionSequence.compile_option =
+	      {frozen_string_literal: true}
+	    p 'foo'.frozen? #=> false, because this line is already compiled.
+	    p eval("'foo'.frozen?") #=> true
+
+	  Details:
+	    * String literals are deduped by rb_fstring().
+	    * Dynamic string literals ("...#{xyz}...") is now only frozen,
+	      not deduped. Maybe you have other ideas.
+
+	  Now, please do not use this option on your productions :)
+	  Of course, current specification can be changed.
+
+	* compile.c: ditto.
+
+	* test/ruby/test_iseq.rb: add a test.

+
+	* method.h: introduce rb_callable_method_entry_t to remove
+	  rb_control_frame_t::klass.
+	  [Bug #11278], [Bug #11279]
+
+	  rb_method_entry_t data belong to modules/classes.
+	  rb_method_entry_t::owner points defined module or class.
+
+	    module M
+	      def foo; end
+	    end
+
+	  In this case, owner is M.
+
+	  rb_callable_method_entry_t data belong to only classes.
+	  For modules, MRI creates corresponding T_ICLASS internally.
+	  rb_callable_method_entry_t can also belong to T_ICLASS.
+
+	  rb_callable_method_entry_t::defined_class points T_CLASS or
+	  T_ICLASS.
+	  rb_method_entry_t data for classes (not for modules) are also
+	  rb_callable_method_entry_t data because it is completely same data.
+	  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
+
+	  For example, there are classes C and D, and includes M,
+
+	    class C; include M; end
+	    class D; include M; end
+
+	  then, two T_ICLASS objects for C's super class and D's super class
+	  will be created.
+
+	  When C.new.foo is called, then M#foo is searched and
+	  rb_callable_method_t data is used by VM to invoke M#foo.
+
+	  rb_method_entry_t data is only one for M#foo.
+	  However, rb_callable_method_entry_t data are two (and can be more).
+	  It is proportional to the number of including (and prepending)
+	  classes (the number of T_ICLASS which point to the module).
+
+	  Now, created rb_callable_method_entry_t are collected when
+	  the original module M was modified. We can think it is a cache.
+
+	  We need to select what kind of method entry data is needed.
+	  To operate definition, then you need to use rb_method_entry_t.
+
+	  You can access them by the following functions.
+
+	  * rb_method_entry(VALUE klass, ID id);
+	  * rb_method_entry_with_refinements(VALUE klass, ID id);
+	  * rb_method_entry_without_refinements(VALUE klass, ID id);
+	  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
+
+	  To invoke methods, then you need to use rb_callable_method_entry_t
+	  which you can get by the following APIs corresponding to the
+	  above listed functions.
+
+	  * rb_callable_method_entry(VALUE klass, ID id);
+	  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
+	  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
+	  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
+
+	  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
+	  returns rb_callable_method_entry_t.
+	  You can check a super class of current method by
+	  rb_callable_method_entry_t::defined_class.
+
+	* method.h: renamed from rb_method_entry_t::klass to
+	  rb_method_entry_t::owner.
+
+	* internal.h: add rb_classext_struct::callable_m_tbl to cache
+	  rb_callable_method_entry_t data.
+
+	  We need to consider about this field again because it is only
+	  active for T_ICLASS.

+
+	* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
+	  because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,

+
+	* process.c (proc_exec_sh): Because proc_exec_sh() may be called
+	  by rb_proc_exec() with envp_str = Qfalse, execl() is replaced
+	  by a macro that calls execle() with "extern char **environ"
+	  traditional global variable on Solaris 10.
+	  TODO: This may be unsafe and should be changed in the future.
+	  Although rb_proc_exec() is not used from inside current version

+	  * NOEX_RESPONDS    -> BOUND_RESPONDS (macro)
+
+	  Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
+
+	  Background:
+	    I did not know what "NOEX" stands for.
+	    I asked Matz (who made this name) and his answer was "Nothing".
+	    "At first, it meant NO EXport (private), but the original
+	    meaning was gone."
+	    This is why I remove the mysterious word "NOEX" from MRI.
+
+	* vm_core.h: introduce `enum missing_reason' to represent

+
+	* eval_intern.h: introduce rb_scope_visibility_t to represent

+	  children of [Old obj] at the beginning of marking.
+
+	  Added (but disabled) code changes current behaviour. This fix promote
+	  [New obj] to old and marks as a remembered old object. We can assume
+	  "new objects referred from old objects are maybe long-lived old
+	  objects".
+
+	  Disadvantage of added algorithm is we may promote unwilling
+	  short-lived objects. For example, consider many new objects push and
+	  pop to an old stack object. All of new objects (short-lived objects)
+	  promote to old objects unexpectedly.
+
+	  To compare these behaviour, I add this new code (but disabled it).

+
+	* internal.h: remove struct method_table_wrapper.
+	  struct method_table_wrapper was introduced to avoid duplicate marking
+	  for method tables.
+
+	  For example, `module M1; def foo; end; end` make one method table
+	  (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
+	  Classes C1 and C2 includes M1, then two T_ICLASS objects are created
+	  and they points mtbl too. In this case, three objects (one T_MODULE
+	  and two T_ICLASS objects) points same mtbl. On marking phase, these
+	  three objects mark same mtbl. To avoid such duplication, struct
+	  method_table_wrapper was introduced.
+
+	  However, created two T_ICLASS objects have same or shorter lifetime
+	  than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
+	  not from T_ICLASS objects. This patch tries marking only from M1.
+	  In other words, original module (M1) has responsibility to mark mtbl.
+	  Because of no duplicate marking, we don't need method_table_wrapper
+	  any more.
+
+	  Note that one `Module#prepend` call creates two T_ICLASS objects.
+	  One for referring to a prepending Module object, same as
+	  `Module#include`. We don't need to care this T_ICLASS.
+	  One for moving original mtbl from a prepending class. We need to
+	  mark such mtbl from this T_ICLASS object. To mark the mtbl,
+	  we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
+	  class `klass`.

+	  2) Prohibit GC while invoking T_DATA/T_FILE data structure

+
+	  This patch can introduce another memory consuming issue because
+	  Ruby-level finalizers can run after (2), GC is disabled.
+	  However, basically object consistency was broken at (2) as I
+	  described above. So that running Ruby-level finalizers contains
+	  danger originally. Because of this point, I need to suggest to
+	  remove these 3 lines (invoking remaining finalizers). And add a
+	  rule to add that finalizers should not add new finalizers, or
+	  say there is no guarantee to invoke finalizers that added by
+	  another finalizer.

+
+	* configure.in (WARN_UNUSED_RESULT): moved to here.
+
+	* configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration
+	  to return int rather than void, because it makes no sense for a
+	  warn_unused_result attributed function to return void.
+
+	  Funny thing however is that it also makes no sense for noreturn
+	  attributed function to return int.  So there is a fundamental
+	  conflict between them.  While I tested this, I confirmed both
+	  GCC 6 and Clang 3.8 prefers int over void to correctly detect
+	  necessary attributes under this setup.  Maybe subject to change
+	  in future.
+
+	* internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then

+
+	* string.c (rb_str_modify_expand): Check that the new length is in the

+	  Therefore simply rshift and cast as signed long works fine.

+	  is not defined when ext/openssl is built with OpenSSL 1.1.0.

+Sun Jun 19 21:25:43 2016  Kazuki Yamaguchi  <k@rhe.jp>
+
+	* ext/openssl/ossl_ocsp.c: Add OCSP::SingleResponse that represents an
+	  OCSP SingleResponse structure. Also add two new methods #responses
+	  and #find_response to OCSP::BasicResponse. A BasicResponse has one or
+	  more SingleResponse. We have OCSP::BasicResponse#status that returns
+	  them as an array of arrays, each containing the content of a
+	  SingleResponse, but this is not useful. When validating an OCSP
+	  response, we need to look into the each SingleResponse and check their
+	  validity but it is not simple. For example, when validating for a
+	  certificate 'cert', the code would be like:
+
+	    # certid_target is an OpenSSL::OCSP::CertificateId for cert
+	    basic = res.basic
+	    result = basic.status.any? do |ary|
+	      ary[0].cmp(certid_target) &&
+	        ary[4] <= Time.now && (!ary[5] || Time.now <= ary[5])
+	    end
+
+	  Adding OCSP::SingleResponse at the same time allows exposing
+	  OCSP_check_validity(). With this, the code above can be rewritten as:
+
+	    basic = res.basic
+	    single = basic.find_response(certid_target)
+	    result = single.check_validity

+	  objects. Currently they accepts only relative seconds from the current
+	  time. This is inconvenience, especially for revocationTime. When
+	  Integer is passed, they are still treated as relative times. Since the
+	  type check is currently done with rb_Integer(), this is a slightly
+	  incompatible change. Hope no one passes a relative time as String or
+	  Time object...
+	  Also, allow passing nil as nextUpdate. It is optional.

+
+	* ext/openssl/ossl_ssl.c (ossl_sslctx_s_alloc): Enable the automatic
+	  curve selection for ECDH by calling SSL_CTX_set_ecdh_auto(). With
+	  this a TLS server automatically selects a curve which both the client
+	  and the server support to use in ECDH. This changes the default
+	  behavior but users can still disable ECDH by excluding 'ECDH' cipher
+	  suites from the cipher list (with SSLContext#ciphers=). This commit
+	  also deprecate #tmp_ecdh_callback=. It was added in Ruby 2.3.0. It
+	  wraps SSL_CTX_set_tmp_ecdh_callback() which will be removed in OpenSSL
+	  1.1.0. Its callback receives two values 'is_export' and 'keylength'
+	  but both are completely useless for determining a curve to use in

+
+	  (ossl_sslctx_set_ecdh_curves): Add SSLContext#ecdh_curves=. Wrap

+
+	* ext/openssl/lib/openssl/ssl.rb (SSLSocket): Move the implementation of
+	  SSLSocket#initialize to C. Initialize the SSL (OpenSSL object) in it.
+	  Currently this is delayed until ossl_ssl_setup(), which is called from
+	  SSLSocket#accept or #connect. Say we call SSLSocket#hostname= with an
+	  illegal value. We expect an exception to be raised in #hostname= but
+	  actually we get it in the later SSLSocket#connect. Because the SSL is
+	  not ready at #hostname=, the actual call of SSL_set_tlsext_host_name()
+	  is also delayed.
+	  This also fixes: [ruby-dev:49376] [Bug #11724]
+
+	* ext/openssl/ossl_ssl.c (ossl_ssl_initialize): Added. Almost the same

+
+	  (ossl_ssl_setup): Adjust to the changes. Just set the underlying IO to
+	  the SSL.

+	  (ssl_started): Added. Make use of SSL_get_fd(). This returns -1 if not

+	  (ossl_ssl_data_get_struct): Removed. Now GetSSL() checks that the SSL
+	  exists.

+	  (ossl_ssl_set_session): Don't call ossl_ssl_setup() here as now the
+	  SSL is already instantiated in #initialize.

+
+	  (Init_ossl_ssl): Add method declarations of SSLSocket#{initialize,

+Mon Apr  4 17:43:45 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: change default value of
+	  RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2
+	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65
+
+	  These values are same as Ruby 2.0.0.
+
+	  This change cause GC counts.
+	  However, generational GC reduced each (minor) GC time and
+	  increase memory locality. So that not so big impact on my
+	  benchmarking results.
+	  (surprisingly, this fix speed up programs on some cases)
+
+	  You can change these values by environment variables
+	  if you feel wrong.
+
+Mon Apr  4 17:36:52 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c (get_envparam_double): take an upper_bound.
+
+	  And also take an accept_zero flag which allow to accept zero
+	  even if lower_bound is set.
+
+	* gc.c (ruby_gc_set_params): fix parameters.
+
+	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO set 0.9 as *lower_bound*, so that
+	  it should be upper_bound.
+	  Set RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO as lower bound.
+
+	  Also set lower/upper bound of RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO to
+	  RUBY_GC_HEAP_FREE_SLOTS_MIN/MAX_RATIO.

+
+Fri Apr  1 20:58:33 2016  Martin Duerst  <duerst@it.aoyama.ac.jp>
+
+	* enc/unicode/case-folding.rb, casefold.h: Data generation to implement
+	  swapcase functionality for titlecase characters. Swapcase isn't defined
+	  by Unicode, because the purpose/usage of swapcase is unclear anyway.
+	  The implementation follows a proposal from Nobu, swapping the case of
+	  each component of a titlecase character individually.
+	  This means that the titlecase characters have to be decomposed.
+
+	* enc/unicode.c: Code using the above data.
+
+	* test/ruby/enc/test_case_mapping.rb: Tests for the above.
+
+Fri Apr  1 14:55:28 2016  Kazuki Yamaguchi  <k@rhe.jp>
+
+	* configure.in (AC_CONFIG_FILES): $srcdir/.git can be a file pointing
+	  the real git_dir, such as when the git working tree is a "linked
+	  working tree" (a working tree created by git-worktree). So use
+	  git-rev-parse --git-dir to check if $srcdir is the top-level of a git
+	  repository, not just checking if the $srcdir/.git directory does exist
+	  or not.  [ruby-core:74759] [Bug #12239]
+
+	* tool/change_maker.rb: use tool/vcs.rb to detect VCS. This used to have
+	  its own VCS detection code, while we have tool/vcs.rb.
+
+	* tool/vcs.rb (detect): remove code duplication

+
+Thu Mar 31 19:16:16 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: need to set initial value of GC_HEAP_FREE_SLOTS_GOAL_RATIO.
+
+Thu Mar 31 17:50:27 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: change additional allocation policy.
+
+	  Introduce new environment variable
+	  RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the
+	  ratio of additional memory.
+
+	  Before this change, we add pages with the following formula
+	  (when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO):
+	    next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR
+
+	  This addition can allocate too much.
+
+	  With this change, we increase pages to satisfy the following formula:
+	    next_free_slots = next_total_slots * goal_ratio
+	  where
+	    next_free_slots = free_slots + adding_slots
+	    next_total_slots = total_slots + adding_slots.
+
+	  If you want to prepare many free slots, increase this ratio.
+
+	  If this variable is 0, then simply multiply
+	  RUBY_GC_HEAP_GROWTH_FACTOR.
+
+	* gc.c (get_envparam_double): enable to accept 0.
+
+Thu Mar 31 17:48:25 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c (gc_marks_finish): fix syntax error.
+
+Thu Mar 31 16:49:36 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: simplify allocate/free detecting logic at the end of marking.
+
+	  Before this change, heap_pages_min_slots are calculated at the
+	  beginning sweeping phase. And this value is used at the end of
+	  *next* marking phase.
+
+	  To simplify it, we use this value at the end of this marking phase.
+	  It means that we don't need to store this value as global state.
+
+	  Also heap_pages_max_slots is calculated at the begging of sweeping
+	  phase and used at the end of sweeping phase.
+	  To simplify this logic, we introduced new global value
+	  heap_pages_freeable_pages it means extra pages count we can free.
+	  gc_sweep_step() checks this value and moves empty pages to tomb_heap
+	  not more than this value.
+
+	  Because of this fix, heap_pages_swept_slots is no longer needed.
+
+	* gc.c (rb_objspace_t::heap_pages): restruct the objspace global
+	  status.
+
+	  remove the following fields
+	    * swept_slots (and heap_pages_swept_slots)
+	    * min_free_slots (and heap_pages_min_free_slots)
+	    * max_free_slots (and heap_pages_max_free_slots)
+	  And add the following filed.
+	    * freeable_pages (and heap_pages_freeable_pages)
+
+	* gc.c (heap_pages_free_unused_pages): unlink tomb heap pages
+	  because tomb heap should have only freeable pages.
+
+	* gc.c (heap_extend_pages): add parameters for future extension.
+
+Thu Mar 31 16:43:02 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: add GC parameters to configure the following values:
+	  * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO:
+	    allocate additional pages when free slots is lower than
+	    the value (total_slots * (this ratio)).
+	  * RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO:
+	    allow to free pages when free slots is greater than
+	    the value (total_slots * (this ratio)).
+
+	  Before this change, these values are hard coded.
+
+	* gc.c (ruby_gc_params_t): ditto.
+
+	* gc.c (ruby_gc_set_params): ditto.
+
+Thu Mar 31 15:59:17 2016  Koichi Sasada  <ko1@atdot.net>

+
+	* gc.c (gc_verify_heap_pages): check also tomb heap.
+

+
+	* gc.c (gc_page_sweep): return free slots count.
+
+	* gc.c (gc_sweep_step): use returned free slots count.
+
+	* gc.c (gc_sweep_step): change variable name `next'
+	  to `next_sweep_page'.

+
+	  r53381 changed to accept only Symbol or String for accessors, but
+	  there are several rubygems that pass classes (e.g. Array,
+	  Hash, ...) as accessors. Prior r53381, it was accepted because Class#to_s
+	  returns its class name. After r53381 given accessors are checked
+	  with define_method, but it accepts only Symbol or String, otherwise
+	  raises TypeError.
+
+	      def_delegator Foo, :some_method
+
+	  This change is to revert unexpected incompatibility. But this behavior
+	  may change in the future.

-= command line options
-
-: -W option
-
-  new option to specify warning level. -W0 to shut up warnings, -W1 for normal level,
-  -W2 for verbose level.  -w equals to -W2.
-
-= language syntax
-
-: arbitrary delimited string array
-
-  %W(...) notation, word list literal like %w(...) with the
-  exception that #{} interpolation is allowed.
-
-: arbitrary delimited symbol literl
-
-  :"foo", :"foo#{bar}", etc.
-
-: expression interpolation in strings
-
-  Now arbitrary statements are allowed inside #{} interpolation
-  without escapes.  In other hand, they can no longer access to
-  variables defined in eval.
-
-: negative number literals
-
-  Digits preceded minus sign is a literal integer.
-
-: array expansion
-
-  Fixed with the following behavior:
-
-    a = *[1]
-    p a #=> [1]
-
-  Now 1-element array in rhs is expanded properly.
-
-    a = *[1]
-    p a #=> 1
-
-: break and next
-
-  Extended to take an optional expression, which is used as a value
-  for termination.
-
-: direct assignment to Foo::Bar is allowed
-
-  also, you can define "class Foo::Bar; end".
-
-= language core
-
-: $stdin, $stdout, $stderr
-
-  can be assignable again.  the original stdio are preserved as STDIN,
-  STDOUT, STDERR.
-
-: $VERBOSE now has 3 levels
-
-  nil - silence, false - medium (default), true - verbose
-
-: allocation framework
-
-  any instance of class can be allocated by class.allocate,
-  (except for a few classes).
-
-: comparison of exception classes in a rescue clause
-
-  changed to use Module#=== for comparing $! with the exception
-  class specified in each rescue clause.
-
-  as the previous behavior was to use kind_of?, the effect is limited
-  to the SystemCallError case.  SystemCallError.=== has been newly
-  defined to return true when the two have the same errno.  With this
-  change, SystemCallError's with the same errno, such as Errno::EAGAIN
-  and Errno::EWOULDBLOCK, can both be rescued by listing just one of
-  them.
-
-: constants lookup
-
-  improved at the performance of searching by using an internal hash
-  table.
-
-  calls const_missing method of the class/module, if constant is not
-  found in the look up path.
-
-: expression parenthesis in the first argument
-
-  altered to get the following code (note the space after p):
-
-    p ("xx"*2).to_i
-
-  Interpreted as:
-
-    p (("xx"*2).to_i)
-
-  Instead of:
-
-    (p("xx"*2)).to_i
-
-: implicit comparison in conditional expressions
-
-  Obsoleted except when it is used in -e.
-
-  : between Range and $.
-      Use explicit comparison instead.
-
-  : between Regexp and $_
-      Use the unary method ~/re/ instead.
-
-: to_str
-
-  added to get objects which define to_str() treated as String's.
-
-  now almost all the built-in methods try each argument with to_str()
-  when they expect it to be a String.
-
-    foo = Object.new
-    class <<foo
-      def to_str
-        "foo"
-      end
-    end
-    p File.open(foo)
-    => -:7:in `open': wrong argument type Object (expected String) (TypeError)
-       ruby 1.6.4 (2001-04-19) [i586-linux]
-    => -:7:in `open': No such file or directory - "foo" (Errno::ENOENT)
-       ruby 1.7.0 (2001-05-02) [i586-linux]
-
-: multiple assignment behavior
-
-  Fixed so that "*a = nil" results in "a == []".
-
-= changes in core class library

-  calls open(2) instead of fopen(3).
-
-: sprintf

-
-  Proc object returns from these methods has the following attributes:
-

-  a method to give warnings.
-

-
-  Added. [ruby-talk:14289]
-
-  This is much the same as (({ary[n,0] = [other,...]})) except
-  returing self.
-
-    ary = [0,1,2,3]
-    ary[2, 0] = [4, 5, 6]
-    p ary
-
-    ary = [0,1,2,3]
-    ary.insert(2, 4, 5, 6)
-    p ary
-
-: Array#sort!
-
-  Changed to always return self without checking whether the sequence

-
-  if "sep" argument is a string, regular expression meta characters
-  are escaped internally.
-
-: String#rstrip
-
-  chop off NULs at the end of strings.
-
-: String#to_i
-
-  Now accepts optional base argument.
-

-
-: String#eql?
-
-  Changed to be always case sensitive.
-
-: String#insert(n, other)
-
-  Added.
-
-  This is much the same as (({str[n, 0] = other})) except returing
-  self.
-
-: String#lstrip, rstrip, lstrip!, rstrip!
-
-  Added.  These strip only left or right part of a string.

-
-  Localism is FNM_DOTMATCH which has the opposite meaning of the
-  commonly known FNM_PERIOD, which does not exist in Ruby.
-

+= NEWS for Ruby 1.8.7
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.8.6 release
+
+=== Configuration changes
+
+* default C flags
+
+  Some C compiler flags may be added by default depending on your
+  environment.  Specify optflags=.. and warnflags=.. as necessary to
+  override them.
+
+* vendor_ruby directory
+
+  A new library directory named `vendor_ruby' is introduced in
+  addition to `site_ruby'.  The idea is to separate libraries
+  installed by the package system (`vendor') from manually (`site')
+  installed libraries preventing the former from getting overwritten
+  by the latter, while preserving the user option to override vendor
+  libraries with site libraries. (`site_ruby' takes precedence over
+  `vendor_ruby')
+
+  If you are a package maintainer, make each library package configure
+  the library passing the `--vendor' option to `extconf.rb' so that
+  the library files will get installed under `vendor_ruby'.
+
+  You can change the directory locations using configure options such
+  as `--with-sitedir=DIR' and `--with-vendordir=DIR'.

+    * Shellwords.escape
+    * Array#shelljoin
+    * String#shellescape
+
+  * Add shorthand methods:
+    * Shellwords.split (alias shellwords)
+    * String#shellsplit
+
+* stringio
+
+  * StringIO#getbyte
+  * StringIO#readbyte
+

+  * StringIO#chars
+
+    New methods.
+
+  * StringIO#each
+  * StringIO#each_line

+
+    Return an enumerator if no block is given.
+
+* tempfile

+      Tempfile.open(['image', 'jpg']) { |tempfile| ... }
+
+* tmpdir
+
+  * New method:
+

+  * content:encoded with RSS 2.0 support
+
+=== Interpreter Implementation
+
+* passing a block to a Proc [experimental]
+
+  This implementation in current shape is known to be buggy/broken,
+  especially with nested block invocation.  Take this as an
+  experimental feature.
+
+* stack trace
+
+  On non-SystemStackError exception, full stack trace is shown.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* String#slice! had some unintentional bugs and they have been fixed
+  because either they disagreed with documentation or their respective
+  behavior of #slice.  Unfortunately, this causes some
+  incompatibilities in the following (somewhat rare) cases.
+
+  * #slice! no longer expands the array when an out-of-boundary value
+    is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2,nil,nil]
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2]
+
+  * #slice! no longer raises an exception but returns nil when a
+    negative length or out-of-boundary negative position is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(1,-1)  #=> (raises IndexError)
+      a.slice!(-5,1)  #=> (raises IndexError)
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(1,-1)  #=> nil
+      a.slice!(-5,1)  #=> nil
+
+* String#to_i, String#hex and String#oct no longer accept a sequence
+  of underscores (`__') as part of a number.
+
+    # Ruby 1.8.6
+    '1__0'.to_i     #=> 10
+    '1__0'.to_i(2)  #=> 2  # 0b10
+    '1__0'.oct      #=> 8  # 010
+    '1__0'.hex      #=> 16 # 0x10
+
+    # Ruby 1.8.7
+    '1__0'.to_i     #=> 1
+    '1__0'.to_i(2)  #=> 1
+    '1__0'.oct      #=> 1
+    '1__0'.hex      #=> 1
+
+  The old behavior was inconsistent with Ruby syntax and considered as
+  a bug.
+
+* date
+
+  * Date.parse
+
+    '##.##.##' (where each '#' is a digit) is now taken as 'YY.MM.DD'
+    instead of 'MM.DD.YY'.  While the change may confuse you, you can
+    always use Date.strptime() when you know what you are dealing
+    with.
+
+* REXML
+
+  * REXML::Document.entity_expansion_limit=
+
+    New method to set the entity expansion limit. By default the limit is
+    set to 10000.  See the following URL for details.
+
+    https://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
+
+* stringio
+
+  * StringIO#each_byte
+
+    The return value changed from nil to self.  This is what the
+    document says and the same as each_line() does.
+
+* tempfile
+
+  * The file name format has changed.  No dots are included by default
+    in temporary file names any more.  See above for how to specify a
+    suffix.
+
+* uri
+
+  * See above for details.
+
+== Changes since the 1.8.5 release
+
+=== New platforms/build tools support
+
+* IA64 HP-UX
+
+* Visual C++ 8 SP1
+
+* autoconf 2.6x
+
+=== Global constants
+
+* RUBY_PATCHLEVEL
+
+  New constant since 1.8.5-p1.
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * New method: Kernel#instance_variable_defined?
+
+  * New method: Module#class_variable_defined?
+
+  * New feature: Dir::glob() can now take an array of glob patterns.
+
+* date
+
+  * Updated based on date2 4.0.3.
+
+* digest
+
+  * New internal APIs for C and Ruby.
+
+  * Support for autoloading.
+
+      require 'digest'
+
+      # autoloads digest/md5
+      md = Digest::MD5.digest("string")
+
+  * New digest class methods: file
+
+  * New digest instance methods: clone, reset, new, inspect,
+    digest_length (alias size or length), block_length()
+
+  * New library: digest/bubblebabble
+
+  * New function: Digest(name)
+
+* fileutils
+
+  * New option for FileUtils.cp_r(): :remove_destination
+
+* nkf
+
+  * Updated based on nkf as of 2007-01-28.
+
+* thread
+
+  * Replaced with much faster mutex implementation in C.  The former
+    implementation, which is slow but considered to be stable, is
+    available with a configure option `--disable-fastthread'.
+
+* tk
+
+  * Updated Tile extension support based on Tile 0.7.8.
+
+  * Support --without-X11 configure option for non-X11 versions of
+    Tcl/Tk (e.g. Tcl/Tk Aqua).
+
+  * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble
+    about STDIN blocking on Windows.
+
+* webrick
+
+  * New method: WEBrick::Cookie.parse_set_cookies()
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* builtin classes
+
+  * String#intern now raises SecurityError when $SAFE level is greater
+    than zero.
+
+* date
+
+  * Time#to_date and Time#to_datetime are added as private methods.
+    They cause name conflict error in ActiveSupport 1.4.1 and prior,
+    which comes with Rails 1.2.2 and prior.  Updating ActiveSupport
+    and/or Rails to the latest versions fixes the problem.
+
+* digest
+
+  * The constructor does no longer take an initial string to feed.
+    The following examples show how to migrate:
+
+      # Before
+      md = Digest::MD5.new("string")
+      # After (works with any version)
+      md = Digest::MD5.new.update("string")
+
+      # Before
+      hd = Digest::MD5.new("string").hexdigest
+      # After (works with any version)
+      hd = Digest::MD5.hexdigest("string")
+
+  * Digest::Base#==
+
+    * self == string
+
+      Automatic detection between binary digest values and hexadecimal
+      digest values has been dropped.  It is always assumed that a
+      hexadecimal digest value is given for comparison.
+
+    * self == md
+
+      Digest objects are compared by the resulting digest values, not
+      by the exact vector states.
+
+* fileutils
+
+  * A minor implementation change breaks Rake <=0.7.1.
+    Updating Rake to 0.7.2 or higher fixes the problem.
+
+* tk
+
+  * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable
+    (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available,
+    but it is an alias name.

+= NEWS for Ruby 1.9.1
+
+This document is a list of user visible feature changes made between

+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes

+
+== Changes since the 1.8.7 release
+See doc/NEWS-1.8.7 for changes between 1.8.6 and 1.8.7.
+
+=== Compatibility issues
+
+* language core
+
+    * New syntax and semantics
+          o Block arguments are always local
+          o New semantics for block arguments
+          o defined? and local variables
+          o Parser expects that your source code has only valid byte
+            sequence in some character encoding.  Use magic comments
+            to tell the parser which encoding you use.
+          o New semantics for constant definition in instance_eval
+            or in module_eval.
+
+    * Deprecated syntax
+          o colon (:) instead of "then" in if/unless or case expression.
+          o retry in a loop or an iterator.
+
+* builtin classes and objects
+
+    * Kernel and Object
+          o Kernel#methods and #singleton_methods used to return an
+            array of strings but now they return an array of symbols.
+    * Class and Module
+          o Module#attr works as Module#attr_reader by default.
+	    Optional boolean argument is obsolete.
+          o Module#instance_methods, #private_instance_methods and
+            #public_instance_methods used to return an array of
+            strings but now they return an array of symbols.
+          o Extra subclassing check when binding UnboundMethods
+
+    * Exceptions
+          o Exceptions are equal to each other if they belong to
+            the same class and have the same message and backtrace.
+          o SystemStackError used to be a subclass of StandardError
+            but not it is a direct subclass of Exception.
+          o SecurityError: ditto
+          o Removed Exception#to_str [Ruby2]
+
+    * Enumerable and Enumerator
+          o Enumerable::Enumerator, compatibility alias of Enumerator,
+            is removed.
+          o Enumerable#{map,collect} called without a block returns
+            an enumerator.
+          o Even more builtin and bundled libraries have been made to
+            return an enumerator when called without a block.
+    * Array
+          o Array#nitems was removed (use count {|i| !i.nil?})
+          o Array#choice was removed (use sample)
+          o Array#[m,n] = nil places nil in the array.
+    * Hash
+          o Hash#to_s is equivalent to Hash#inspect
+          o Semantics for Hash#each and Hash#each_pair
+          o Hash#select returns a hash
+          o Hash#key is the new name for #index which has been
+            deprecated.
+          o Hash preserves order.  It enumerates its elements in the
+            order in which the keys are inserted.
+          o Most of the changes in Hash apply to hash like interfaces
+            such as ENV and *DBM.
+    * IO operations
+          o Many methods used to act byte-wise but now some of those act
+            character-wise. You can use alternate byte-wise methods.
+          o IO#getc
+          o Non-blocking IO
+          o Kernel#open takes "t" for newline conversion
+          o Kernel#open takes encoding specified
+          o IO automatically converts byte sequence from a character
+            encodings into another if specified.
+          o StringIO#readpartial
+          o IO.try_convert
+          o IO.binread
+          o IO.copy_stream
+          o IO#binmode?
+          o IO#close_on_exec= and IO#close_on_exec?
+          o Limit input in IO#gets, IO#readline, IO#readlines,
+            IO#each_line, IO#lines, IO.foreach, IO.readlines,

+          o Directive %u behaves like %d for negative values in
+            printf-style formatting.
+    * File and Dir operations
+          o #to_path is called as necessary in File.path, File.chmod,
+            File.lchmod, File.chown, File.lchown, File.utime,
+            File.unlink, etc..

+                byte-wise.
+                  o String#[]: Indexing a String with an integer returns a
+                    single character String instead of an integer.
+                  o String#[]=: No longer takes an integer as right
+                    side value.  Note that "str[i] = ?c" because of
+                    the following change.
+                  o ?c is evaluated to a single character string
+                    instead of an integer.
+    * Regexp
+          o Encoding-awareness
+          o Regexp matches only with strings which is encoded in a
+            compatible character encoding to the regexp's.
+          o Regexp#kcode is removed. use Regexp#encoding.
+    * Symbols: restriction on literal symbols

+          o Kernel#to_a
+          o Kernel#getc, #gsub, #sub

+            features of each class.
+          o VERSION and friends
+
+* bundled libraries
+
+    * Pathname
+          o No longer has #to_str nor #=~.
+    * time and date
+          o Time.parse and Date.parse interprets slashed numerical dates
+	    as "dd/mm/yyyy".

+= NEWS for Ruby 1.9.3
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.9.2 release
+=== License
+
+* Ruby's License is changed from a dual license with GPLv2
+  to a dual license with 2-clause BSDL.
+
+=== Known platform dependent issues
+==== OS X Lion
+
+* You have to configure ruby with '--with-gcc=gcc-4.2' if you're using
+  Xcode 4.1, or, if you're using Xcode 4.2, you have to configure ruby
+  with '--with-gcc=clang'.
+
+=== C API updates
+
+* rb_scan_args() is enhanced with support for option hash argument
+  extraction.
+
+* ruby_vm_at_exit() added.  This enables extension libs to hook a VM
+  termination.
+
+* rb_reserved_fd_p() added.  If you want to close all file descriptors,
+  check using this API.  [ruby-core:37759]
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * ARGF
+    * new methods:
+      * ARGF.print
+      * ARGF.printf
+      * ARGF.putc
+      * ARGF.puts
+      * ARGF.read_nonblock
+      * ARGF.to_write_io
+      * ARGF.write
+
+  * Array
+    * extended method:
+      * Array#pack supports endian modifiers
+
+  * Bignum
+    * Multiplication algorithm for Bignums with a large number of digits over
+      150 BDIGITs is changed in order to reduce its calculation time.
+      Now such large Bignums are multiplied by using Toom-3 algorithm.
+
+  * Encoding
+    * new encodings:
+      * CP950
+      * CP951
+      * UTF-16
+      * UTF-32
+    * change alias:
+      * SJIS is Windows-31J
+
+  * File
+    * new constant:
+      * File::NULL
+        name of NULL device.
+      * File::DIRECT
+        name of O_DIRECT.
+
+  * IO
+    * extended method:
+      * IO#putc supports multibyte characters
+    * new methods:
+      * IO#advise
+      * IO.write(name, string, [offset] )
+        Write `string` to file `name`.
+        Opposite with File.read.
+      * IO.binwrite(name, string, [offset] )
+        binary version of IO.write.
+
+  * Kernel
+    * move #__id__ to BasicObject.
+    * extended method:
+      * Kernel#rand supports range argument
+
+  * Module
+    * new methods:
+      * Module#private_constant
+      * Module#public_constant
+
+  * Random
+    * extended method:
+      * Random.rand supports range argument
+
+  * String
+    * extended method:
+      * String#unpack supports endian modifiers
+    * new method:
+      * String#prepend
+      * String#byteslice
+
+  * Time
+    * extended method:
+      * Time#strftime supports %:z and %::z.
+
+  * Process
+    * Process#maxgroups and Process#maxgroups= now raise NotImplementedError if
+      the platform don't support supplementary groups concept.
+
+* bigdecimal
+
+  * BigDecimal#power and BigDecimal#** support non-integral exponent.
+
+  * Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
+    Rational, Float, and BigDecimal.  If you pass a Rational or a Float to
+    them, you must specify the precision to produce the digits of a BigDecimal.
+
+  * The behavior of BigDecimal#coerce with a Rational is changed.  It uses
+    the precision of the receiver BigDecimal to produce the digits of a
+    BigDecimal from the given Rational.
+
+* bigdecimal/util
+
+  * BigDecimal#to_d and Integer#to_d are added.
+
+  * Float#to_d accepts a precision.
+
+  * Rational#to_d raises ArgumentError when passing zero or negative
+    precision.
+
+  * Rational#to_d
+
+    * Zero and an implicit precision is deprecated.
+      This feature is removed at the next release of bigdecimal.
+
+    * A negative precision isn't supported.
+      Be careful it is an incompatible change.
+
+* date
+
+  * Accepts flonum explicitly with limitations.
+    * If the given offset is flonum, DateTime assumes its precision is
+      at most second.
+
+      DateTime.new(2001,2,3,0,0,0,3.0/24) ==
+      DateTime.new(2001,2,3,0,0,0,'+03:00')
+        #=> true
+
+    * If the given operand for -/+ is flonum, DateTime assumes its
+      precision is at most nanosecond.
+
+      DateTime.new(2001,2,3) + 0.5 == DateTime.new(2001,2,3,12)
+        #=> true
+
+    * Precision of offset is always at most second.
+
+      Rational('0.5') == Rational('0.500001')  #=> false
+      DateTime.new(2001,2,3,0,0,0,Rational('0.5')) ==
+      DateTime.new(2001,2,3,0,0,0,Rational('0.500001'))
+        #=> true
+
+  * Ignores long offset and far reform day (with warning).
+
+    * Now accepts only:
+
+      -1<=offset<=1 (-24:00..+24:00)
+      2298874<=start<=2426355 or -/+oo
+        (proleptic Gregorian/Julian mean -/+oo)
+
+  * A method strftime cannot produce huge output (same as Time's one).
+
+    * Even though Date/DateTime can handle far dates, the following causes
+      an exception.
+
+      DateTime.new(1<<10000).strftime('%Y')  # Errno::ERANGE
+
+  * Changed the format of inspect.
+  * Changed the format of marshal (but, can load old dumps).
+
+* io/console
+  * new methods:
+    * IO#noecho {|io| }
+    * IO#echo=
+    * IO#echo?
+    * IO#raw {|io| }
+    * IO#raw!
+    * IO#getch
+    * IO#winsize
+    * IO.console
+
+* json
+  * updated to v1.5.4.
+
+* matrix
+  * new classes:
+    * Matrix::EigenvalueDecomposition
+    * Matrix::LUPDecomposition
+  * new methods:
+    * Matrix#diagonal?
+    * Matrix#eigen
+    * Matrix#eigensystem
+    * Matrix#hermitian?
+    * Matrix#lower_triangular?

+    * Matrix#lup_decomposition
+    * Matrix#normal?
+    * Matrix#orthogonal?
+    * Matrix#permutation?
+    * Matrix#round
+    * Matrix#symmetric?
+    * Matrix#unitary?
+    * Matrix#upper_triangular?
+    * Matrix#zero?
+    * Vector#magnitude, #norm
+    * Vector#normalize
+  * extended methods:
+    * Matrix#each and #each_with_index can iterate on a subset of the elements
+    * Matrix#find_index returns [row, column] and can iterate on a subset
+      of the elements
+    * Matrix#** implements Numeric exponents (using the eigensystem)
+    * Matrix.zero can build rectangular matrices
+
+* minitest
+  * Minitest has been updated to version 2.2.2.
+  * For full details, see https://github.com/seattlerb/minitest/blob/master/History.txt
+
+* net/http
+  * SNI (Server Name Indication) supported for HTTPS.
+
+  * Allow to configure to wait server returning '100 continue' response
+    before sending HTTP request body. Set Net::HTTP#continue_timeout AND pass
+    'expect' => '100-continue' to a extra HTTP header.
+
+    For example, the following code sends HTTP header and waits for getting
+    '100 continue' response before sending HTTP request body. When 0.5 [sec]
+    timeout occurs or the server send '100 continue', the client sends HTTP
+    request body.
+      http.continue_timeout = 0.5
+      http.request_post('/continue', 'body=BODY', 'expect' => '100-continue')
+

+    * ObjectSpace::memsize_of_all
+
+* openssl
+  * PKey::RSA and PKey::DSA now use the generic X.509 encoding scheme
+    (e.g. used in a X.509 certificate's Subject Public Key Info) when
+    exporting public keys to DER or PEM. Backward compatibility is
+    ensured by (already existing) fallbacks during creation.
+  * OpenSSL::ASN1::Constructive#new and OpenSSL::ASN1::Primitive#new
+    (and the constructors of their sub-classes) will no longer force
+    tagging to be set to :EXPLICIT when tag and/or tag_class are passed
+    as parameters. tagging must be set explicitly.
+  * Support for infinite length encodings via infinite_length attribute.
+  * OpenSSL::PKey.read( file | string [, pwd] ) allows to read arbitrary
+    public/private keys in DER-/PEM-encoded form with an optional password
+    for encrypted PEM encodings.
+  * Add new method OpenSSL::X509::Name#hash_old as a wrapper of
+    X509_NAME_hash_old() defined from OpenSSL 1.0.0. It returns OpenSSL 0.9.8
+    compatible hash value.
+
+* optparse
+  * support for bash/zsh completion.

+      test result.
+
+* uri
+  * new methods:
+    * URI::Generic#hostname
+    * URI::Generic#hostname=
+
+* webrick
+  * new method:

+      loaded.
+
+* Module

+
+* Range

+    from a method or a block.
+  * added RubyVM::InstructionSequence#path, #absolute_path, #label,
+    #base_label and #first_lineno to retrieve information from where
+    the instruction sequence was defined.
+  * added Environment variables to specify stack usage:

+      instance variable names.
+
+* Thread
+  * added method:

+  * new class Thread::Backtrace::Location to hold backtrace location
+    information. These are returned by Thread#backtrace_locations and
+    Kernel#caller_locations.
+  * incompatible changes:
+    * Thread#join and Thread#value now raises a ThreadError if target thread
+      is the current or main thread.
+
+* Time

+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Array#values_at
+
+  See above.
+
+* String#lines
+* String#chars
+* String#codepoints
+* String#bytes
+
+  These methods no longer return an Enumerator, although passing a
+  block is still supported for backwards compatibility.
+
+  Code like str.lines.with_index(1) { |line, lineno| ... } no longer
+  works because str.lines returns an array.  Replace lines with
+  each_line in such cases.
+
+* IO#lines
+* IO#chars
+* IO#codepoints
+* IO#bytes
+* ARGF#lines
+* ARGF#chars
+* ARGF#bytes
+* StringIO#lines
+* StringIO#chars
+* StringIO#codepoints
+* StringIO#bytes
+* Zlib::GzipReader#lines
+* Zlib::GzipReader#bytes
+
+  These methods are deprecated in favor of each_line, each_byte,
+  each_char and each_codepoint.
+
+* Proc#==
+* Proc#eql?
+
+  These methods were removed. Two procs are == only when they are
+  the same object.
+
+* Fixnum
+* Bignum
+* Float
+
+  Fixnums, Bignums and Floats are frozen.
+
+* Signal.trap
+
+  See above.
+
+* Merge Onigmo.
+  https://github.com/k-takata/Onigmo
+
+* The :close_others option is true by default for system() and exec().
+  Also, the close-on-exec flag is set by default for all new file descriptors.
+  This means file descriptors doesn't inherit to spawned process unless
+  explicitly requested such as system(..., fd=>fd).
+
+* Kernel#respond_to? against a protected method now returns false
+  unless the second argument is true.
+
+* Kernel#respond_to_missing?
+* Kernel#initialize_clone
+* Kernel#initialize_dup
+
+  These methods are now private.
+
+* Thread#join, Thread#value
+
+  See above.
+
+* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
+
+  See above.
+
+=== Stdlib updates (outstanding ones only)
+
+* cgi
+  * Add HTML5 tag maker.
+  * CGI#header has been renamed to CGI#http_header and
+    aliased to CGI#header.
+  * When HTML5 tagmaker called, overwrite CGI#header,
+    CGI#header function is to create a <header> element.
+
+* CSV
+  * Removed CSV::dump and CSV::load to protect users from dangerous
+    serialization vulnerability
+
+* iconv
+  * Iconv has been removed. Use String#encode instead.
+
+* io/console
+  * new methods:
+    * added IO#cooked which sets the terminal to cooked mode within the given block.
+    * added IO#cooked! which sets the terminal to cooked.
+  * extended method:
+    * IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
+
+* io/wait
+  * new features:
+    * added IO#wait_writable method.
+    * added IO#wait_readable method as alias of IO#wait.
+
+* json
+  * updated to 1.7.7.
+
+* net/http
+  * new features:
+    * Proxies are now automatically detected from the http_proxy environment
+      variable.  See Net::HTTP::new for details.
+    * gzip and deflate compression are now requested for all requests by
+      default.  See Net::HTTP for details.
+    * SSL sessions are now reused across connections for a single instance.
+      This speeds up connection by using a previously negotiated session.
+    * Requests may be created from a URI which sets the request_uri and host
+      header of the request (but does not change the host connected to).
+    * Responses contain the URI requested which allows easier implementation of
+      redirect following.
+  * new methods:
+    * Net::HTTP#local_host
+    * Net::HTTP#local_host=
+    * Net::HTTP#local_port
+    * Net::HTTP#local_port=
+  * extended method:
+    * Net::HTTP#connect uses local_host and local_port if specified.
+
+* net/imap
+  * new methods:
+    * Net::IMAP.default_port
+    * Net::IMAP.default_imap_port
+    * Net::IMAP.default_tls_port
+    * Net::IMAP.default_ssl_port
+    * Net::IMAP.default_imaps_port
+
+* objspace
+  * new method:
+    * ObjectSpace.reachable_objects_from(obj)
+
+* openssl
+  * Consistently raise an error when trying to encode nil values. All instances
+    of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
+    instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
+    raise NoMethodError in the same case. Constructing such values is still
+    permitted.
+  * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
+    :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
+    :TLSv1_1_client. The version being effectively used can be queried
+    with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
+    blacklist the new TLS versions with OpenSSL::SSL::OP_NO_TLSv1_1 and
+    OpenSSL::SSL::OP_NO_TLSv1_2.
+  * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
+    may be set which gets called whenever a new handshake is negotiated. This
+    also allows to programmatically decline (client) renegotiation attempts.
+  * Support for "0/n" splitting of records as BEAST mitigation via
+    OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
+  * The default options for OpenSSL::SSL::SSLContext have changed to
+    OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
+    instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
+    the BEAST attack by default.
+  * OpenSSL requires passwords for decrypting PEM-encoded files to be at least
+    four characters long. This led to awkward situations where an export with
+    a password with fewer than four characters was possible, but accessing the
+    file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
+    OpenSSL::PKey::EC therefore now enforce the same check when exporting a
+    private key to PEM with a password - it has to be at least four characters
+    long.
+  * SSL/TLS support for the Next Protocol Negotiation extension. Supported
+    with OpenSSL 1.0.1 and higher.
+  * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
+    is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
+    manually in order to adapt to situations where FIPS mode would be an
+    explicit requirement.
+  * Authenticated Encryption with Associated Data (AEAD) is supported via
+    Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
+    Currently (OpenSSL 1.0.1c), only GCM mode is supported.
+
+* ostruct
+  * new methods:
+    * OpenStruct#[], []=
+    * OpenStruct#each_pair
+    * OpenStruct#eql?
+    * OpenStruct#hash
+    * OpenStruct#to_h converts the struct to a hash.
+  * extended method:
+    * OpenStruct.new also accepts an OpenStruct / Struct.
+
+* pathname
+  * extended method:
+    * Pathname#find returns an enumerator if no block is given.
+
+* rake
+  * rake has been updated to version 0.9.5.
+
+    This version is backwards-compatible with previous rake versions and
+    contains many bug fixes.
+
+    See
+    http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
+    of changes in rake 0.9.3, 0.9.4 and 0.9.5.
+
+* RDoc
+  * RDoc has been updated to version 4.0
+
+    This version is largely backwards-compatible with previous rdoc versions.
+    The most notable change is an update to the ri data format (ri data must
+    be regenerated for gems shared across rdoc versions).  Further API changes
+    are internal and won't affect most users.
+
+    Notable changes include:
+
+    * Page support for ri.  Try `ri ruby:` for a list of pages in ruby or
+      `ri ruby:syntax/literals` for the syntax documentation for literals.
+
+      This also works for gems such as `ri rspec:README` for the rspec gem's
+      README file.
+    * Markdown support.  See ri RDoc::Markdown for details.
+
+    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
+    of changes in rdoc 4.0.
+
+* resolv
+  * new methods:
+    * Resolv::DNS#timeouts=
+    * Resolv::DNS::Config#timeouts=
+
+* rexml
+  * REXML::Document#write supports Hash arguments.
+  * REXML::Document#write supports new :encoding option. It changes
+    XML document encoding. Without :encoding option, encoding in
+    XML declaration is used for XML document encoding.
+
+* RubyGems
+  * Updated to 2.0.0
+
+    RubyGems 2.0.0 features the following improvements:
+
+    * Improved support for default gems shipping with ruby 2.0.0+
+    * A gem can have arbitrary metadata through Gem::Specification#metadata
+    * `gem search` now defaults to --remote and is anchored like gem list.
+    * Added --document to replace --rdoc and --ri.  Use --no-document to
+      disable documentation, --document=rdoc to only generate rdoc.
+    * Only ri-format documentation is generated by default.
+    * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
+      documentation.
+
+    For an expanded list of updates and bug fixes see:
+    https://github.com/rubygems/rubygems/blob/master/History.txt
+
+* shellwords
+  * Shellwords#shellescape now stringifies the given object using to_s.
+  * Shellwords#shelljoin accepts non-string objects in the given
+    array, each of which is stringified using to_s.
+
+* stringio
+  * deprecated methods:
+    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
+
+* syslog
+  * Added Syslog::Logger which provides a Logger API atop Syslog.
+  * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
+    are introduced for easy detection of available constants on a
+    running system.
+
+* tmpdir
+  * incompatible changes:
+    * Dir.mktmpdir uses FileUtils.remove_entry instead of
+      FileUtils.remove_entry_secure.  This means that applications should not
+      change the permission of the created temporary directory to make
+      writable from other users.
+
+* yaml
+  * Syck has been removed.  YAML now completely depends on libyaml being
+    installed.
+  * libyaml is now bundled with ruby, for cases where the library is not
+    installed locally.
+
+* zlib
+  * Added streaming support for Zlib::Inflate and Zlib::Deflate.  This allows
+    processing of a stream without the use of large amounts of memory.
+  * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
+  * Zlib streams are now processed without the GVL.  This allows gzip, zlib and
+    deflate streams to be processed in parallel.
+  * deprecated methods:
+    * Zlib::GzipReader#lines and #bytes are deprecated.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* OpenStruct new methods can conflict with custom attributes named
+  "each_pair", "eql?", "hash" or "to_h".
+
+* Dir.mktmpdir in lib/tmpdir.rb
+
+  See above.
+
+=== C API updates
+
+* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
+
+* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.

+= NEWS for Ruby 2.1.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 2.0.0 release
+
+=== Language changes
+
+* Now the default values of keyword arguments can be omitted.  Those
+  "required keyword arguments" need giving explicitly at the call time.
+
+* Added suffixes for integer and float literals: 'r', 'i', and 'ri'.
+  * "42r" and "3.14r" are evaluated as Rational(42, 1) and 3.14.rationalize,
+    respectively.  But exponential form with 'r' suffix like "6.022e+23r" is
+    not accepted because it is misleading.
+  * "42i" and "3.14i" are evaluated as Complex(0, 42) and Complex(0, 3.14),
+    respectively.
+  * "42ri" and "3.14ri" are evaluated as Complex(0, 42r) and Complex(0, 3.14r),
+    respectively.
+
+* def-expr now returns the symbol of its name instead of nil.

+    * String#scrub and String#scrub! verify and fix invalid byte sequence.
+      If you want to use this function with older Ruby,
+      consider to use string-scrub.gem.
+
+* Symbol
+  * All symbols are now frozen.
+
+* pack/unpack (Array/String)
+  * Q! and q! directives for long long type if platform has the type.
+
+* toplevel
+  * extended methods:
+    * main.using is no longer experimental. The method activates refinements
+      in the ancestors of the argument module to support refinement
+      inheritance by Module#include.
+
+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Hash
+  * incompatible changes:
+    * Hash#reject will return plain Hash object in the future versions, that
+      is the original object's subclass, instance variables, default value,
+      and taintedness will be no longer copied, so now warnings are emitted
+      when called with such Hash.
+
+* IO
+  * incompatible changes:
+    * open ignore internal encoding if external encoding is ASCII-8BIT.
+
+* Kernel#eval, Kernel#instance_eval, and Module#module_eval.
+  * Copies the scope information of the original environment, which means
+    that private, protected, public, and module_function without arguments
+    do not affect the environment outside the eval string.
+    For example, `class Foo; eval "private"; def foo; end; end' doesn't make
+    Foo#foo private.
+
+* Kernel#untrusted?, untrust, and trust
+  * These methods are deprecated and their behavior is the same as tainted?,
+    taint, and untaint, respectively.  If $VERBOSE is true, they show warnings.
+
+* Module#ancestors
+  * The ancestors of a singleton class now include singleton classes,
+    in particular itself.
+
+* Module#define_method and Object#define_singleton_method
+  * Now they return the symbols of the defined methods, not the methods/procs
+    themselves.
+
+* Numeric#quo
+  * Raises TypeError instead of ArgumentError if the receiver doesn't have
+    to_r method.
+
+* Proc
+  * Returning from lambda proc now always exits from the Proc, not from the
+    method where the lambda is created.  Returning from non-lambda proc exits
+    from the method, same as the former behavior.
+
+String
+  * If invalid: :replace is specified for String#encode, replace
+    invalid byte sequence even if the destination encoding equals to
+    the source encoding.
+
+=== Stdlib updates (outstanding ones only)
+
+* CGI::Util
+  * All class methods modulized.
+
+* Digest
+  * extended methods:
+    * Digest::Class.file takes optional arguments for its constructor
+
+* Matrix
+  * Added Vector#cross_product.
+
+* Net::SMTP
+  * Added Net::SMTP#rset to implement the RSET command
+
+* objspace
+  * new method:
+    * ObjectSpace.trace_object_allocations
+    * ObjectSpace.trace_object_allocations_start
+    * ObjectSpace.trace_object_allocations_stop
+    * ObjectSpace.trace_object_allocations_clear
+    * ObjectSpace.allocation_sourcefile
+    * ObjectSpace.allocation_sourceline
+    * ObjectSpace.allocation_class_path
+    * ObjectSpace.allocation_method_id
+    * ObjectSpace.allocation_generation
+    * ObjectSpace.reachable_objects_from_root
+    * ObjectSpace.dump
+    * ObjectSpace.dump_all
+
+* OpenSSL::BN
+  * extended methods:
+    * OpenSSL::BN.new allows Fixnum/Bignum argument.
+
+* open-uri
+  * Support multiple fields with same field name (like Set-Cookie).
+
+* Pathname
+  * New methods:
+    * Pathname#write
+    * Pathname#binwrite
+
+* rake
+  * Updated to 10.1.0.  Major changes include removal of the class namespace,
+    Rake::DSL to hold the rake DSL methods and removal of support for legacy
+    rake features.
+
+    For a complete list of changes since rake 0.9.6 see:
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_1_0_rdoc.html
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_0_3_rdoc.html
+
+* RbConfig
+  * New constants:
+    * RbConfig::SIZEOF is added to provide the size of C types.
+
+* RDoc
+  * Updated to 4.1.0.  Major enhancements include a modified default template
+  * and accessibility enhancements.
+
+    For a list of minor enhancements and bug fixes see:
+    https://github.com/rdoc/rdoc/blob/v4.1.0.preview.1/History.rdoc
+
+* Resolv
+  * New methods:
+    * Resolv::DNS.fetch_resource
+  * One-shot multicast DNS support
+  * Support LOC resources
+
+* REXML::Parsers::SAX2Parser
+  * Fixes wrong number of arguments of entitydecl event. Document of the event
+    says "an array of the entity declaration" but implementation passes two
+    or more arguments. It is an implementation bug but it breaks backward
+    compatibility.
+
+* REXML::Parsers::StreamParser
+  * Supports "entity" event.
+
+* REXML::Text
+  * REXML::Text#<< supports method chain like 'text << "XXX" << "YYY"'.
+  * REXML::Text#<< supports not "raw" mode.
+
+* Rinda::RingServer, Rinda::RingFinger
+  * Rinda now supports multicast sockets.  See Rinda::RingServer and
+    Rinda::RingFinger for details.
+
+* RubyGems
+  * Updated to 2.2.0.  Notable new features include:
+
+    * Gemfile or gem.deps.rb support including Gem.file.lock (experimental)
+    * Improved, iterative resolver (compared to RubyGems 2.1 and earlier)
+    * Support for a sharing a GEM_HOME across ruby platforms and versions
+
+    For a complete list of enhancements and bug fixes see:
+    https://github.com/rubygems/rubygems/tree/master/History.txt
+
+* Set
+  * New methods:
+    * Set#intersect?
+    * Set#disjoint?
+
+* Socket
+  * New methods:
+    * Socket.getifaddrs
+
+* StringScanner
+  * extended methods:
+    * StringScanner#[] supports named captures.
+
+* Syslog::Logger
+  * Added facility.
+
+* Tempfile
+  * New methods:
+    * Tempfile.create
+
+* Timeout
+  * The exception to terminate the given block can no longer be rescued
+    inside the block, by default, unless the exception class is given
+    explicitly.
+
+* TSort
+  * New methods:
+    * TSort.tsort
+    * TSort.tsort_each
+    * TSort.strongly_connected_components
+    * TSort.each_strongly_connected_component
+    * TSort.each_strongly_connected_component_from
+
+* WEBrick
+  * The body of a response may now be a StringIO or other IO-like that responds
+    to #readpartial and #read.
+
+* XMLRPC::Client
+  * New methods:
+    * XMLRPC::Client#http. It returns Net::HTTP for the client. Normally,
+      it is not needed. It is useful when you want to change minor HTTP client
+      options. You can change major HTTP client options by XMLRPC::Client
+      methods. You should use XMLRPC::Client methods for changing major
+      HTTP client options instead of XMLRPC::Client#http.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* Set
+  * incompatible changes:
+    * Set#to_set now returns self instead of generating a copy.
+
+* URI
+  * incompatible changes:
+    * URI.decode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to specify the character encoding.
+      It now allows loose percent encoded strings, but denies ;-separator.
+    * URI.encode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to convert before percent encode.
+      UTF-16 strings aren't converted to UTF-8 before percent encode by default.
+
+* curses
+  * Removed.
+    curses is now available as a gem.
+    See https://rubygems.org/gems/curses for details.
+
+=== Built-in global variables compatibility issues
+
+* $SAFE
+  * $SAFE=4 is obsolete.  If $SAFE is set to 4 or larger, an ArgumentError
+    is raised.
+
+=== C API updates
+
+* rb_gc_set_params() is deprecated. This is only used in Ruby internal.
+
+* rb_gc_count() added. This returns the number of times GC occurred.
+
+* rb_gc_stat() added. This allows access to specific GC.stat() values from C
+  without any allocation overhead.
+
+* rb_gc_latest_gc_info() added. This allows access to GC.latest_gc_info().
+
+* rb_postponed_job_register() added. Takes a function callback which is invoked
+  when the VM is in a consistent state, i.e. to perform work from a C signal
+  handler.
+
+* rb_profile_frames() added. Provides low-cost access to the current ruby stack
+  for callstack profiling.
+
+* rb_tracepoint_new() supports new internal events accessible only from C:
+  * RUBY_INTERNAL_EVENT_NEWOBJ
+  * RUBY_INTERNAL_EVENT_FREEOBJ
+  * RUBY_INTERNAL_EVENT_GC_START
+  * RUBY_INTERNAL_EVENT_GC_END_MARK
+  * RUBY_INTERNAL_EVENT_GC_END_SWEEP
+  * Note that you *can not* specify "internal events" with normal events
+    (such as RUBY_EVENT_CALL, RUBY_EVENT_RETURN) simultaneously.

+  * Improvements
+    * Introduce incremental marking for major GC. [Feature #10137]
+
+* IO
+  * Improvements
+    * IO#read_nonblock and IO#write_nonblock for pipes on Windows are supported.
+
+* Kernel
+  * New methods:

+      there is no corresponding catch block, instead of ArgumentError.
+
+* Process
+  * Extended method:
+    * Process execution methods such as Process.spawn opens the file in write
+      mode for redirect from [:out, :err].
+
+* String
+  * New methods:
+    * String#unicode_normalize
+    * String#unicode_normalize!
+    * String#unicode_normalized?
+
+* Symbol
+  * Improvements
+    * Most symbols which are returned by String#to_sym and
+      String#intern are GC-able.
+
+* Method
+  * New methods:
+    * Method#curry([ arity ]) returns a curried Proc.

+  * Enumerable#chunk's state management deprecated.
+
+* GC
+  * incompatible changes:
+    * Rename GC.stat entries. [Feature #9924]

+      { **hash1, **hash2 } contains values of hash2 for duplicated keys.
+
+* IO
+  * incompatible changes:
+    * When flushing file IO with IO#flush, you cannot assume that the metadata
+      of the file is updated immediately.  On some platforms (especially
+      Windows), it is delayed until the filesystem load is decreased.
+      Use IO#fsync if you want to guarantee updating metadata.
+
+* Math
+  * incompatible changes:
+    * Math.log now raises Math::DomainError instead of returning NaN if the
+      base is less than 0, and returns NaN instead of -infinity if both of
+      two arguments are 0.
+    * Math.atan2 now returns values like as expected by C99 if both two
+      arguments are infinity.
+
+* Proc
+  * incompatible changes:
+    * ArgumentError is no longer raised when lambda Proc is passed as a
+      block, and the number of yielded arguments does not match the formal
+      arguments of the lambda, if just an array is yielded and its length
+      matches.
+
+* Process
+  * Process execution methods such as Process.spawn opens the file in write
+    mode for redirect from [:out, :err].
+    Before Ruby 2.2, it was opened in read mode.
+
+=== Stdlib updates (outstanding ones only)
+
+* Continuation
+  * callcc is obsolete. use Fiber instead.
+
+* Digest
+
+  * Digest() should now be thread-safe.  If you have a problem with
+    regard to on-demand loading under a multi-threaded environment,
+    preload "digest/*" modules on boot or use this method instead of
+    directly referencing Digest::*.
+  * Digest::HMAC has been removed just as previously noticed.
+
+* DL
+  * DL has been removed from stdlib. Please use Fiddle instead!
+
+* Etc
+  * New methods:
+    * Etc.uname
+    * Etc.sysconf
+    * Etc.confstr
+    * IO#pathconf
+    * Etc.nprocessors
+
+* Find, Pathname

+
+* Matrix
+  * New methods:
+    * Matrix#first_minor(row, column) returns the submatrix obtained
+      by deleting the specified row and column.
+    * Matrix#cofactor(row, column) returns the (row, column) cofactor
+      which is obtained by multiplying the first minor by (-1)**(row + column).
+    * Matrix#adjugate returns the adjugate of the matrix.
+    * hstack and vstack are new instance and class methods to stack matrices
+      horizontally and vertically.
+    * Matrix#laplace_expansion(row_or_column: num) returns the laplace_expansion
+      along the +num+ -th row or column.
+    * Vector.basis(size:, index:) returns the specified basis vector.
+    * Unary - and + added for Vector and Matrix.
+    * Vector#cross_product generalized to arbitrary dimensions.
+    * Vector#dot and #cross are aliases for #inner_product and #cross_product.
+    * Vector#angle_with returns the angle with its argument
+    * New instance and class method independent? to test linear independence.
+
+* Pathname
+  * Pathname#/ is aliased to Pathname#+.
+  * New methods:
+    * Pathname#birthtime
+
+* Rake

+
+* ext/date/lib/date/format.rb
+  * Removed because it's empty file.
+
+* Digest
+  * Digest::HMAC has finally ceased to exist.  Use OpenSSL::HMAC or an external gem instead.
+
+* time.rb
+  * Time.parse, Time.strptime, Time.rfc2822, Time.xmlschema may produce
+    fixed-offset Time objects.
+    It is happen when usual localtime doesn't preserve the offset from UTC.
+  * Time.httpdate produces always UTC Time object.
+  * Time.strptime raises ArgumentError when no date information.
+
+* lib/rational.rb

+* Psych
+  * Removed Psych::EngineManager [Bug #8344]
+
+=== Built-in global variables compatibility issues
+
+=== C API updates
+
+* Deprecated APIs removed.  [Feature #9502]
+
+  Check_SafeStr -> SafeStringValue
+  rb_check_safe_str -> SafeStringValue
+  rb_quad_pack -> rb_integer_pack
+  rb_quad_unpack -> rb_integer_unpack
+  rb_read_check : access struct FILE internal. no replacement.
+  rb_struct_iv_get : internal function. no replacement.
+  struct rb_blocking_region_buffer : internal type. no replacement.
+  rb_thread_blocking_region_begin -> rb_thread_call_without_gvl family
+  rb_thread_blocking_region_end -> rb_thread_call_without_gvl family
+  TRAP_BEG -> rb_thread_call_without_gvl family
+  TRAP_END -> rb_thread_call_without_gvl family
+  rb_thread_select -> rb_thread_fd_select
+  struct rb_exec_arg : internal type. no replacement.
+  rb_exec : internal function. no replacement.
+  rb_exec_arg_addopt : internal function. no replacement.
+  rb_exec_arg_fixup : internal function. no replacement.
+  rb_exec_arg_init : internal function. no replacement.
+  rb_exec_err : internal function. no replacement.
+  rb_fork : internal function. no replacement.
+  rb_fork_err : internal function. no replacement.
+  rb_proc_exec_n : internal function. no replacement.
+  rb_run_exec_options : internal function. no replacement.
+  rb_run_exec_options_err : internal function. no replacement.
+  rb_thread_blocking_region -> rb_thread_call_without_gvl family
+  rb_thread_polling -> rb_thread_wait_for
+  rb_big2str0 : internal function. no replacement.
+  rb_big2ulong_pack -> rb_integer_pack
+  rb_gc_set_params : internal function. no replacement.
+  rb_io_mode_flags -> rb_io_modestr_fmode
+  rb_io_modenum_flags -> rb_io_oflags_fmode
+
+* struct RBignum is hidden.  [Feature #6083]
+  Use rb_integer_pack and rb_integer_unpack instead.
+
+* struct RRational is hidden.  [Feature #9513]
+  Use rb_rational_num and rb_rational_den instead.
+
+* rb_big_new and rb_big_resize takes a size_t instead of long.
+
+* rb_num2long returns a long instead of SIGNED_VALUE.
+
+* rb_num2ulong returns an unsigned long instead of VALUE.
+
+* st hash table uses power-of-two sizes for speed [Feature #9425].
+  Lookups are 10-25% faster if using appropriate hash functions.
+  However, weaknesses in hash distribution can no longer be masked
+  by prime number-sized tables, so extensions may need to tweak
+  hash functions to ensure good distribution.
+
+* rb_sym2str() added. This is almost same as `rb_id2str(SYM2ID(sym))`
+  but not pinning a dynamic symbol.
+
+* rb_str_cat_cstr() added. This is the same as `rb_str_cat2()`.
+
+* `rb_str_substr()` and `rb_str_subseq()` will share middle of a string,
+  but not only the end of a string, in the future.  Therefore, result
+  strings may not be NUL-terminated, `StringValueCStr()` is needed
+  calling to obtain a NUL-terminated C string.
+
+* rb_tracepoint_new() supports new internal events accessible only from C:
+  * RUBY_INTERNAL_EVENT_GC_ENTER
+  * RUBY_INTERNAL_EVENT_GC_EXIT
+    r47528
+
+* rb_hash_delete() now does not call the block given to the current method.
+
+* rb_extract_keywords() and rb_get_kwargs() exported.  See README.EXT
+  for details.
+
+=== Build system updates
+
+* jemalloc is optionally supported via `./configure --with-jemalloc`
+  jemalloc may be suitable when system malloc is slow or prone
+  to fragmentation.  [Feature #9113]
+
+=== Implementation changes
+
+* GC
+    * Most symbols which are returned by String#to_sym and
+      String#intern are GC-able [Feature #9634]
+    * Introduce incremental marking for major GC. [Feature #10137]
+    * Enable lazy sweep on GC caused by malloc().
+
+* VM
+    * Use frozen string literals for Hash#[] and Hash#[]=
+    * Fast keyword arguments passing [Feature #10440]
+    * Allow to receive huge splatted array by a rest argument [Feature #10440]
+
+* Process
+    * Process creation methods, such as spawn(), uses vfork() system call.
+      vfork() is faster than fork() when the parent process uses huge memory.

+
+== Changes since the 2.2.0 release
+
+=== Language changes
+
+* frozen-string-literal pragma:
+
+  * new pragma, frozen-string-literal has been experimentally introduced. [Feature #8976]
+  * besides, --enable/--disable=frozen-string-literal options also have
+    been introduced. [Feature #8976]
+  * command line options --debug or --debug=frozen-string-literal enable
+    additional debugging mode which shows created location with at frozen
+    object error (RuntimeError). [Feature #11725]
+
+* safe navigation operator:
+
+  * new method call syntax, `object&.foo', method #foo is called on
+    `object' if it is not nil. [Feature #11537]
+
+    This is similar to `try!' in Active Support, except:
+    * method name is syntactically required
+          obj.try! {} # valid
+          obj&. {}    # syntax error
+    * arguments are evaluated only if a call is made:
+          obj.try!(:foo, bar())  # bar() is always evaluated
+          obj&.foo(bar())        # bar() is conditionally evaluated
+    * attribute assignment is valid
+          obj&.attr += 1
+

+    http://docs.seattlerb.org/rubygems/History_txt.html#label-2.5.1+-2F+2015-12-10
+
+=== Built-in global variables compatibility issues
+
+* $SAFE
+  * $SAFE=2 and $SAFE=3 are obsolete.  If $SAFE is set to 2 or larger,
+    an ArgumentError is raised.  [Feature #5455]
+
+=== C API updates
+
+* rb_define_class_id_under() now raises a TypeError exception when the
+  class is already defined but its superclass does not match the given
+  superclass, as well as definitions in ruby level.
+
+* rb_timespec_now() is added to fetch current datetime as struct timespec. [Feature #11558]

+
+* OS/2 is no longer supported
+
+* BeOS is no longer supported
+
+* Borland-C is no longer supported
+
+* Haiku now stable and best effort
+
+=== Implementation improvements
+
+* Optimize Proc#call to eliminate method frame construction. [Feature #11569]
+
+* Reconsidering method entry data structure. [Bug #11278]
+
+* Introducing new table data structure for ID keys tables used by
+  method table and so on. New table structure is simple and fast
+  than st_table. [Feature #11420]
+
+* Machine code level tuning for object allocation and method calling
+  code. r52099, r52254
+
+* RubyVM::InstructionSequence is extended for future improvement. [Feature #11788]
+
+* Case dispatch is now optimized for all special constant literals
+  including nil, true, and false.  Previously, only literal strings,
+  symbols, integers and floats compiled to optimized case dispatch. [Feature #11769]
+
+* Instance variables on non-pure Ruby classes (T_DATA, T_FILE,
+  etc..) is less expensive to store than before. [Feature #11170]
+
+* All accesses to members of big Struct objects are performed in
+  constant-time.  Previously, Struct elements beyond the first 10
+  elements used a linear scan. [Feature #10585]
+
+* The Set class got several speed up. [Misc #10754], [r52591]
+
+* Socket and I/O-related improvements
+
+  * Calling overhead of most of new keyword-using I/O methods in
+    [Feature #11229] is reduced by avoiding the inefficient C API
+    to parse keywords.  [Feature #11339]
+
+  * The standard library is updated to use the improved
+    exception-free non-blocking I/O from [Feature #11229].
+    This has the additional benefit of quieter $DEBUG output in
+    addition to reducing expensive exceptions. [Feature #11044]
+
+  * (Linux-only) waiting on a single FD anywhere in the stdlib no longer
+    uses select(2), making it immune to slowdowns with high-numbered
+    FDs. [Feature #11081] [Feature #11377]
+
+* CGI.escapeHTML is optimized with C extension.

+
+=== Compatibility issues (excluding feature bug fixes)
+
+* Array#sum and Enumerable#sum are implemented.  [Feature #12217]
+
+  Ruby itself has no compatibility problem because Ruby didn't have sum method
+  for arrays before Ruby 2.4.
+  However many third party gems, activesupport, facets, simple_stats, etc,
+  defines sum method.  These implementations are mostly compatible but
+  there are subtle differences.
+  Ruby's sum method should be mostly compatible but it is impossible to
+  be perfectly compatible with all of them.
+
+* Fixnum and Bignum are unified into Integer  [Feature #12005]
+
+  Fixnum class and Bignum class is removed.
+  Integer class is changed from abstract class to concrete class.
+  For example, 0 is an instance of Integer: 0.class returns Integer.
+  The constants Fixnum and Bignum is bound to Integer.
+  So obj.kind_of?(Fixnum) works as obj.kind_of?(Integer).
+  At C-level, Fixnum object and Bignum object should be distinguished by
+  FIXNUM_P(obj) and RB_TYPE_P(obj, T_BIGNUM).
+  RUBY_INTEGER_UNIFICATION can be used to detect this feature at C-level.
+  0.class == Integer can be used to detect this feature at Ruby-level.
+  The C-level constants, rb_cFixnum and rb_cBignum, are removed.
+  They can cause compilation failure.
+
+* String/Symbol#upcase/downcase/swapcase/capitalize(!) now work for all of
+  Unicode, not only for ASCII. [Feature #10085]
+
+  No change is needed if the data is in ASCII anyway or if the limitation
+  to ASCII was only tolerated while waiting for a more extensive implementation.
+  A change (using the :ascii option) is needed in cases where Unicode data
+  is processed, but the operation has to be limited to ASCII only.
+  A good example of this are internationalized domain names.
+
+* TRUE / FALSE / NIL
+
+  These constants are now obsoleted. [Feature #12574]
+  Use true / false / nil resp. instead.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* DateTime
+
+  * DateTime#to_time now preserves timezone.  [Bug #12189]
+
+* Psych
+
+  * Update to Psych 2.2.2
+
+* RDoc
+
+  * Update to RDoc 5.0.0
+
+* RubyGems
+
+  * Update to RubyGems 2.6.8
+
+* shellwords
+
+  * Shellwords.shellwords (shellsplit) treats the backslash as escape
+    character only when followed by one of the following characters:
+    $ ` " \ <newline> [Bug #10055]
+
+* Time
+
+  * Time#to_time now preserves timezone.  [Bug #12271]
+
+* thread
+
+  * the extension library is removed.  Till 2.0 it was a pure ruby script
+    "thread.rb", which has precedence over "thread.so", and has been provided
+    in $LOADED_FEATURES since 2.1.
+
+* Tk
+
+  * Tk is removed from stdlib.  [Feature #8539]
+
+    https://github.com/ruby/tk is the new upstream.
+
+* XMLRPC
+
+  * XMLRPC is removed from stdlib, and bundled as gem. [Feature #12160][ruby-core:74239]
+
+    https://github.com/ruby/xmlrpc is the new upstream.
+
+* Zlib
+
+  * Zlib.gzip and Zlib.gunzip [Feature #13020]
+
+=== C API updates
+
+* ruby_show_version() will no longer exits the process, if
+  RUBY_SHOW_COPYRIGHT_TO_DIE is set to 0.  This will be the default in
+  the future.
+
+* rb_gc_adjust_memory_usage() [Feature #12690]
+
+=== Supported platform changes
+
+* FreeBSD < 4 is no longer supported
+
+=== Implementation improvements
+
+* In some condition, `[x, y].max` and `[x, y].min` are optimized
+  so that a temporal array is not created.  The concrete condition is
+  an implementation detail: currently, the array literal must have no
+  splat, must have at least one expression but literal, the length must
+  be <= 0x100, and Array#max and min must not be redefined.  It will work
+  in most casual and real-life use case where it is written with intent
+  to `Math.max(x, y)`.
+
+* Thread deadlock detection now shows their backtrace and dependency. [Feature #8214]
+
+* st_table (st.c) internal data structure is improved. [Feature #12142]
+
+* Rational is extensively optimized. [Feature #12484]
+
+=== Miscellaneous changes
+
+* ChangeLog is removed from the repository.
+
+  It is generated from commit messages in Subversion by `make dist`.
+  Also note that now people should follow Git style commit message.
+  The template is written at {Short (50 chars or less) summary of
+  changes}[https://git-scm.com/book/ch5-2.html].  [Feature #12283]

+
+* BigDecimal
+

+
+  * The following features are added:
+
+    * BigDecimal::VERSION
+
+  * The following features have been deprecated,
+    and are planned to be removed in the version 1.4.0:
+
+    * BigDecimal.new
+
+    * BigDecimal.ver
+
+  * BigDecimal#clone and #dup now do not make a new instance,
+    but returns the receiver itself.
+
+* Coverage
+
+  * Support branch coverage and method coverage measurement. [Feature #13901]
+    Branch coverage tells you which branches are executed, and which not.
+    Method coverage tells you which methods are invoked, and which not.
+    By running a test suite with this new feature, you can know which branches
+    and methods are executed by a test, and evaluate total coverage of a test
+    suite more strictly.
+
+    You can specify the measuring target by an option to `Coverage.start`:
+
+        Coverage.start(lines: true, branches: true, methods: true)
+
+    After some Ruby files are loaded, you can use `Coverage.result` to get
+    the coverage result:
+
+        Coverage.result
+        #=> { "/path/to/file.rb"=>
+        #     { :lines => [1, 2, 0, nil, ...],
+        #       :branches =>
+        #         { [:if, 0, 2, 1, 6, 4] =>
+        #             { [:then, 1, 3, 2, 3, 8] => 0,
+        #               [:else, 2, 5, 2, 5, 8] => 2
+        #             }
+        #         },
+        #       :methods => {
+        #          [Object, :foo, 1, 0, 7, 3] => 2
+        #       }
+        #     }
+        #   }
+
+    The result type of line coverage is not changed; it is just an array that
+    contains numbers, which means the count that each line was executed,
+    or `nil`s, which means that the line is not relevant.
+
+    The result type of branch coverage is:
+
+        { (jump base) => { (jump target) => (counter) } }
+
+    where jump base and targets have the format
+
+        [type, unique-id, start lineno, start column, end lineno, end column]
+
+    For example, `[:if, 0, 2, 1, 6, 4]` reads an `if` statement that ranges from
+    line 2 and column 1, to line 6 and column 4.  `[:then, 1, 3, 2, 3, 8]` reads
+    a `then` clause that ranges from line 3 and column 2, to line 3 and column 8.
+    Note that lineno starts from 1, and that columnno starts from 0.  So, the
+    above example shows a branch from the `if` to the `then` was never executed,
+    and a branch from the `if` to the `else` was executed twice.
+
+    The result type of method coverage is:
+
+        { (method key) => (counter) }
+
+    where method key has the format
+
+        [class, method-name, start lineno, start column, end lineno, end column]
+
+    For example, `[Object, :foo, 1, 0, 7, 3]` reads `Object#foo` that ranges from
+    line 1 and column 0, to line 7 and column 3.  The above example shows this
+    `Object#foo` was invoked twice.
+
+    Note: To keep compatibility, passing no option to `Coverage.start` will measure
+    only line coverage, and `Coverage.result` will return the old format:
+
+        Coverage.result
+        #=> { "/path/to/file.rb"=> [1, 2, 0, nil, ...] }
+
+* DRb
+
+  * ACL::ACLEntry.new no longer suppresses IPAddr::InvalidPrefixError.
+
+* ERB
+
+  * Add ERB#result_with_hash to render a template with local variables passed
+    with a Hash object. [Feature #8631]
+
+  * Default template file encoding is changed from ASCII-8BIT to UTF-8 in erb
+    command. [Bug #14095]
+
+  * Carriage returns are changed to be trimmed properly if trim_mode is specified
+    and used. Duplicated newlines will be removed on Windows. [Bug #5339] [Bug #11464]
+
+* IPAddr
+
+  * IPAddr no longer accepts invalid address mask. [Bug #13399]
+  * IPAddr#ipv4_compat and IPAddr#ipv4_compat? are marked for deprecation. [Bug #13769]
+
+  * New methods:
+
+    * IPAddr#prefix
+    * IPAddr#loopback?
+    * IPAddr#private? [Feature #11666]
+    * IPAddr#link_local? [Feature #10912]
+
+* IRB
+
+  * Print backtrace and error message in reverse order [Feature #8661] [experimental]
+  * `binding.irb` automatically requires irb and runs [Bug #13099] [experimental]
+  * `binding.irb` on its start shows source around the line where it was called [Feature #14124]
+
+* Matrix
+
+  * New methods:
+
+    * Matrix.combine and Matrix#combine [Feature #10903]
+    * Matrix#hadamard_product and Matrix#entrywise_product
+
+* Net::HTTP
+
+  * Net::HTTP.new supports no_proxy parameter [Feature #11195]
+  * Net::HTTP#min_version and Net::HTTP#max_version [Feature #9450]
+  * Add more HTTP status classes
+  * Net::HTTP::STATUS_CODES is added as HTTP Status Code Repository [Misc #12935]
+  * Net::HTTP#proxy_user and Net::HTTP#proxy_pass reflect http_proxy environment
+    variable if the system's environment variable is multiuser safe. [Bug #12921]
+
+* open-uri
+  * URI.open method defined as an alias to open-uri's Kernel.open.
+    open-uri's Kernel.open will be deprecated in future.
+

+  instruction to avoid overhead [Feature #14104]
+
+* ERB now generates code from a template twice as fast as Ruby 2.4
+
+=== Miscellaneous changes
+
+* Print backtrace and error message in reverse order if $stderr is unchanged
+  and a tty. [Feature #8661] [experimental]
+
+* Print error message in bold/underlined text if $stderr is unchanged and a
+  tty. [Feature #14140] [experimental]
+
+* configure option --with-ext now mandates its arguments.  So for
+  instance if you run ./configure --with-ext=openssl,+ then the
+  openssl library is guaranteed compiled, otherwise the build fails
+  abnormally.
+
+  Note however to always add the ",+" at the end of the argument.
+  Otherwise nothing but openssl are built.  [Feature #13302]

+= NEWS for Ruby 2.6.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or reference
+information is supplied with.  For a full list of changes with all
+sufficient information, see the ChangeLog file or Redmine
+(e.g. <tt>https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER</tt>)
+
+== Changes since the 2.5.0 release
+
+=== Language changes
+
+* <code>$SAFE</code> now is a process global state and can be set to 0 again. [Feature #14250]
+
+* Refinements take place at block passing.  [Feature #14223]
+
+* Refinements take place at Kernel#public_send.  [Feature #15326]
+
+* Refinements take place at Kernel#respond_to?.  [Feature #15327]
+
+* +else+ without +rescue+ now causes a syntax error.  [EXPERIMENTAL] [Feature #14606]
+
+* Constant names may start with a non-ASCII capital letter. [Feature #13770]
+
+* Endless ranges are introduced.  You can use a Range that has no end,
+  like <code>(0..)</code> (or similarly <code>(0...)</code>).  [Feature #12912]
+
+  The following shows typical use cases:
+
+    ary[1..]                              # identical to ary[1..-1]
+    (1...).each {|index| block }          # infinite loop from index 1
+    ary.zip(1..) {|elem, index| block }   # ary.each.with_index(1) { }
+
+* Non-Symbol keys in a keyword arguments hash cause an exception.
+
+* The "shadowing outer local variable" warning is removed.  [Feature #12490]
+
+  You can now write the following without warning:
+
+    user = users.find {|user| cond(user) }
+
+* Print +cause+ of the exception if the exception is not caught and printed
+  its backtraces and error message. [Feature #8257]
+
+* The flip-flop syntax is deprecated. [Feature #5400]
+
+=== Core classes updates (outstanding ones only)
+
+[Array]
+
+  [New methods]
+
+    * Added Array#union and Array#difference instance methods.  [Feature #14097]

+
+  [Aliased methods]
+
+    * Array#filter is a new alias for Array#select. [Feature #13784]
+    * Array#filter! is a new alias for Array#select!. [Feature #13784]
+
+[Binding]
+
+  [New method]
+
+    * Added Binding#source_location.  [Feature #14230]
+
+      This method returns the source location of the binding, a 2-element
+      array of <code>__FILE__</code> and <code>__LINE__</code>.
+      Traditionally, the same information could be retrieved by
+      <code>eval("[__FILE__, __LINE__]", binding)</code>, but we are
+      planning to change this behavior so that Kernel#eval ignores
+      binding's source location [Bug #4352].  So, users should use this
+      newly-introduced method instead of Kernel#eval.
+
+[Dir]
+
+  [New methods]
+

+    instance of this class from Numeric#step and Range#step.
+
+[Enumerator::Chain]
+
+  * This is a new class to represent a chain of enumerables that works as a
+    single enumerator, generated by such methods as Enumerable#chain and
+    Enumerator#+.
+
+[Enumerator::Lazy]
+
+  [Aliased method]
+
+    * Enumerator::Lazy#filter is a new alias for

+
+  [Aliased methods]
+
+    * Hash#filter is a new alias for Hash#select.  [Feature #13784]
+
+    * Hash#filter! is a new alias for Hash#select!. [Feature #13784]
+
+[IO]
+
+  [New option]
+
+    * Added new mode character <code>'x'</code> to open files for exclusive
+      access. [Feature #11258]
+
+[Kernel]
+

+
+    * Kernel#system and Kernel#exec do not close non-standard file descriptors
+      (the default of the +:close_others+ option is changed to +false+,
+      but we still set the +FD_CLOEXEC+ flag on descriptors we
+      create).  [Misc #14907]
+
+[KeyError]
+
+  [New options]
+
+    * KeyError.new accepts +:receiver+ and +:key+ options to set receiver and
+      key in Ruby code.  [Feature #14313]
+
+[Method]
+

+
+[Module]
+
+  [Modified methods]
+
+    * Module#method_defined?, Module#private_method_defined?, and
+      Module#protected_method_defined? now accept the second
+      parameter as optional. If it is +true+ (the default value), it checks
+      ancestor modules/classes, or checks only the class itself. [Feature #14944]
+
+[NameError]
+
+  [New option]
+
+    * NameError.new accepts a +:receiver+ option to set receiver in Ruby
+      code.  [Feature #14313]

+    * Proc#call doesn't change <code>$SAFE</code> any more.  [Feature #14250]
+
+[Random]
+
+  [New method]
+
+    * Added Random.bytes.  [Feature #4938]
+

+
+  [New method]
+
+    * Added Range#% instance method.  [Feature #14697]
+
+  [Incompatible changes]
+
+    * Range#=== now uses the +#cover?+ instead of the +#include?+ method. [Feature #14575]
+    * Range#cover? now accepts a Range object. [Feature #14473]
+    * Range#step now returns an instance of the Enumerator::ArithmeticSequence
+      class rather than one of the Enumerator class.
+
+[Regexp/String]
+
+    * Update Unicode version from 10.0.0 to 11.0.0. [Feature #14802]

+
+  [Modified method]
+
+    * TracePoint#enable accepts new keywords "target:" and
+      "target_line:".  [Feature #15289]
+
+=== Stdlib updates (outstanding ones only)
+
+[BigDecimal]
+
+  Update to version 1.4.0.  This version includes several compatibility
+  issues, see Compatibility issues section below for details.
+
+  [Modified method]
+
+    * BigDecimal() accepts the new keyword "exception:" similar to Float().
+
+  [Note for the differences among recent versions]
+
+    You should want to know the differences among recent versions of bigdecimal.
+    Please select the suitable version of bigdecimal according to the following
+    information.
+
+    * 1.3.5 has BigDecimal.new without "exception:" keyword.  You can see the
+      deprecation warning of BigDecimal.new when you specify "-w" option.
+      BigDecimal(), BigDecimal.new, and Object#to_d methods are the same.
+
+    * 1.4.0 has BigDecimal.new with "exception:" keyword.  You always see the
+      deprecation warning of BigDecimal.new.  Object#to_d method is different
+      from BigDecimal() and BigDecimal.new.
+
+    * 2.0.0 will be released soon after releasing Ruby 2.6.0.  This version
+      will not have the BigDecimal.new method.
+
+[Bundler]
+
+  * Add Bundler to Standard Library. [Feature #12733]
+
+  * Use 1.17.2, the latest stable version.
+
+[Coverage]
+
+  A oneshot_lines mode is added.  [Feature #15022]
+
+  This mode checks "whether each line was executed at least once or not",
+  instead of "how many times each line was executed".
+  A hook for each line is fired at most once, and after it is fired
+  the hook flag is removed, i.e., it runs with zero overhead.
+
+  [New options]
+
+    * Add +:oneshot_lines+ keyword argument to Coverage.start.
+
+    * Add +:stop+ and +:clear+ keyword arguments to Coverage.result.
+      If +clear+ is true, it clears the counters to zero.
+      If +stop+ is true, it disables coverage measurement.
+
+  [New methods]
+
+    * Coverage.line_stub, which is a simple helper function that
+      creates the "stub" of line coverage from a given source code.
+
+[CSV]
+
+  * Upgrade to 3.0.2. This includes performance improvements especially
+    for writing. Writing is about 2 times faster.
+    See https://github.com/ruby/csv/blob/master/NEWS.md.
+
+[ERB]
+
+  [New options]
+
+    * Add +:trim_mode+ and +:eoutvar+ keyword arguments to ERB.new.
+      Now non-keyword arguments other than the first one are softly deprecated
+      and will be removed when Ruby 2.5 becomes EOL. [Feature #14256]
+
+    * erb command's <tt>-S</tt> option is deprecated, and will be removed
+      in the next version.
+
+[FileUtils]
+
+  [New methods]
+
+    * FileUtils#cp_lr.  [Feature #4189]
+
+[Matrix]
+
+  [New methods]
+
+    * Matrix#antisymmetric?, Matrix#skew_symmetric?
+
+    * Matrix#map!, Matrix#collect! [Feature #14151]
+
+    * Matrix#[]=
+
+    * Vector#map!, Vector#collect!
+
+    * Vector#[]=
+
+[Net]
+
+  [New options]
+
+    * Add +:write_timeout+ keyword argument to Net::HTTP.new. [Feature #13396]
+
+  [New methods]
+
+    * Add Net::HTTP#write_timeout and Net::HTTP#write_timeout=.  [Feature #13396]
+
+  [New constant]
+
+    * Add Net::HTTPClientException to deprecate Net::HTTPServerException,
+      whose name is misleading.  [Bug #14688]
+
+[NKF]
+
+  * Upgrade to nkf v2.1.5
+
+[Psych]
+
+  * Upgrade to Psych 3.1.0
+
+[RDoc]
+
+  * Become about 2 times faster.
+
+  * Use SOURCE_DATE_EPOCH to generate files.
+
+  * Fix method line number that slipped off.
+
+  * Enable <code>--width</code>, <code>--exclude</code>,
+    and <code>--line-numbers</code> that were ignored.
+
+  * Add support for blockquote by ">>>" in default markup notation.
+
+  * Add support for "Raises" lines in TomDoc notation.
+
+  * Fix syntax error output.
+
+  * Fix many parsing bugs.
+
+[REXML]
+
+  * Upgrade to REXML 3.1.9.

+
+    * <code>string()</code> function: Support context node.
+
+    * <code>string()</code> function: Support processing instruction node.

+
+    * <code>"/ #{AXIS}::#{ELEMENT_NAME}"</code> case
+
+    * <code>"#{N}-#{M}"</code> case: One or more white spaces were required
+      before <code>"-"</code>
+
+    * <code>"/child::node()"</code> case
+
+    * <code>"#{FUNCTION}()/#{PATH}"</code> case
+
+    * <code>"@#{ATTRIBUTE}/parent::"</code> case
+
+    * <code>"name(#{NODE_SET})"</code> case
+
+[RSS]
+
+  [New options]
+
+    * RSS::Parser.parse now accepts options as Hash. +:validate+ ,
+      +:ignore_unknown_element+ , +:parser_class+ options are available.
+
+[RubyGems]
+
+  * Upgrade to RubyGems 3.0.1
+
+  * https://blog.rubygems.org/2018/12/19/3.0.0-released.html
+

+
+    * Add URI::File to handle the file URI scheme.  [Feature #14035]
+
+=== Compatibility issues (excluding feature bug fixes)
+
+[Dir]
+
+  * Dir.glob with <code>'\0'</code>-separated pattern list will be deprecated,
+    and is now warned.  [Feature #14643]
+
+[File]
+
+  * File.read, File.binread, File.write, File.binwrite, File.foreach, and
+    File.readlines do not invoke external commands even if the path starts
+    with the pipe character <code>'|'</code>. [Feature #14245]
+
+[Object]
+
+  * Object#=~ is deprecated.  [Feature #15231]
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* These standard libraries have been promoted to default gems.
+
+  * e2mmap
+  * forwardable
+  * irb
+  * logger
+  * matrix
+  * mutex_m
+  * ostruct
+  * prime
+  * rexml
+  * rss
+  * shell
+  * sync
+  * thwait
+  * tracer
+
+[BigDecimal]
+
+  * The following methods are removed.
+
+    * BigDecimal.allocate
+    * BigDecimal.ver
+
+  * Every BigDecimal object is frozen. [Feature #13984]
+
+  * BigDecimal() parses the given string similar to Float().
+
+  * String#to_d parses the receiver string similar to String#to_f.
+
+  * BigDecimal.new will be removed in version 2.0.
+
+[Pathname]
+
+  * Pathname#read, Pathname#binread, Pathname#write, Pathname#binwrite,
+    Pathname#each_line and Pathname#readlines do not invoke external
+    commands even if the path starts with the pipe character <code>'|'</code>.
+    This follows [Feature #14245].
+
+=== Implementation improvements
+
+* Speedup Proc#call because we don't need to care about <code>$SAFE</code>
+  any more. [Feature #14318]
+
+  With +lc_fizzbuzz+ benchmark which uses Proc#call many times we can
+  measure x1.4 improvements.  [Bug #10212]
+
+* Speedup block.call where +block+ is passed block parameter. [Feature #14330]
+
+  Ruby 2.5 improves block passing performance. [Feature #14045]
+
+  Additionally, Ruby 2.6 improves the performance of passed block calling.
+
+* Introduce an initial implementation of a JIT (Just-in-time) compiler. [Feature #14235] [experimental]
+
+  * <tt>--jit</tt> command line option is added to enable JIT. <tt>--jit-verbose=1</tt>
+    is good for inspection.  See <tt>ruby --help</tt> for others.
+  * To generate machine code, this JIT compiler uses the C compiler used for building
+    the interpreter. Currently GCC, Clang, and Microsoft Visual C++ are supported for it.
+  * <tt>--disable-mjit-support</tt> option is added to configure. This is added for JIT debugging,
+    but if you get an error on building a header file for JIT, you can use this option to skip
+    building it as a workaround.
+  * rb_waitpid reimplemented on Unix-like platforms to maintain
+    compatibility with processes created for JIT [Bug #14867]
+
+* VM generator script renewal; makes the generated VM more optimized. [GH-1779]
+
+* Thread cache enabled for pthreads platforms (for Thread.new and
+  Thread.start).  [Feature #14757]
+
+* timer thread is eliminated for platforms with POSIX timers. [Misc #14937]
+
+* Transient Heap (theap) is supported. [Bug #14858] [Feature #14989]
+
+  theap is a managed heap for short-living memory objects. For example,
+  making a small and short-living Hash object is x2 faster. With rdoc benchmark,
+  we measured 6-7% performance improvement.
+
+* Native implementations (arm32, arm64, ppc64le, win32, win64, x86, amd64) of
+  coroutines to improve performance of Fiber significantly. [Feature #14739]
+
+=== Miscellaneous changes
+
+* On macOS, shared libraries no longer include a full version number of Ruby
+  in their names.  This eliminates the burden of each teeny upgrade on the
+  platform that users need to rebuild every extension library.
+
+  [Before]
+    * libruby.2.6.0.dylib
+    * libruby.2.6.dylib -> libruby.2.6.0.dylib
+    * libruby.dylib -> libruby.2.6.0.dylib
+
+  [After]
+    * libruby.2.6.dylib
+    * libruby.dylib -> libruby.2.6.dylib
+

+  * https://speakerdeck.com/k_tsj/pattern-matching-new-feature-in-ruby-2-dot-7
+  * Note that the slides are slightly obsolete.
+
+* The warning against pattern matching can be suppressed with
+  {-W:no-experimental option}[#label-Warning+option].
+
+==== The spec of keyword arguments is changed towards 3.0
+
+* Automatic conversion of keyword arguments and positional arguments is
+  deprecated, and conversion will be removed in Ruby 3.  [Feature #14183]
+
+  * When a method call passes a Hash at the last argument, and when it
+    passes no keywords, and when the called method accepts keywords,
+    a warning is emitted.  To continue treating the hash as keywords,
+    add a double splat operator to avoid the warning and ensure
+    correct behavior in Ruby 3.
+
+      def foo(key: 42); end; foo({key: 42})   # warned
+      def foo(**kw);    end; foo({key: 42})   # warned
+      def foo(key: 42); end; foo(**{key: 42}) # OK
+      def foo(**kw);    end; foo(**{key: 42}) # OK
+
+  * When a method call passes keywords to a method that accepts keywords,
+    but it does not pass enough required positional arguments, the
+    keywords are treated as a final required positional argument, and a
+    warning is emitted.  Pass the argument as a hash instead of keywords
+    to avoid the warning and ensure correct behavior in Ruby 3.
+
+      def foo(h, **kw); end; foo(key: 42)      # warned
+      def foo(h, key: 42); end; foo(key: 42)   # warned
+      def foo(h, **kw); end; foo({key: 42})    # OK
+      def foo(h, key: 42); end; foo({key: 42}) # OK
+
+  * When a method accepts specific keywords but not a keyword splat, and
+    a hash or keywords splat is passed to the method that includes both
+    Symbol and non-Symbol keys, the hash will continue to be split, and
+    a warning will be emitted.  You will need to update the calling code
+    to pass separate hashes to ensure correct behavior in Ruby 3.
+
+      def foo(h={}, key: 42); end; foo("key" => 43, key: 42)   # warned
+      def foo(h={}, key: 42); end; foo({"key" => 43, key: 42}) # warned
+      def foo(h={}, key: 42); end; foo({"key" => 43}, key: 42) # OK
+
+  * If a method does not accept keywords, and is called with keywords,
+    the keywords are still treated as a positional hash, with no warning.
+    This behavior will continue to work in Ruby 3.
+
+      def foo(opt={});  end; foo( key: 42 )   # OK
+
+* Non-symbols are allowed as keyword argument keys if the method accepts
+  arbitrary keywords. [Feature #14183]
+
+  * Non-Symbol keys in a keyword arguments hash were prohibited in 2.6.0,
+    but are now allowed again.  [Bug #15658]
+
+      def foo(**kw); p kw; end; foo("str" => 1) #=> {"str"=>1}
+
+* <code>**nil</code> is allowed in method definitions to explicitly mark
+  that the method accepts no keywords. Calling such a method with keywords
+  will result in an ArgumentError. [Feature #14183]
+
+    def foo(h, **nil); end; foo(key: 1)       # ArgumentError
+    def foo(h, **nil); end; foo(**{key: 1})   # ArgumentError
+    def foo(h, **nil); end; foo("str" => 1)   # ArgumentError
+    def foo(h, **nil); end; foo({key: 1})     # OK
+    def foo(h, **nil); end; foo({"str" => 1}) # OK
+
+* Passing an empty keyword splat to a method that does not accept keywords
+  no longer passes an empty hash, unless the empty hash is necessary for
+  a required parameter, in which case a warning will be emitted.  Remove
+  the double splat to continue passing a positional hash.  [Feature #14183]
+
+    h = {}; def foo(*a) a end; foo(**h) # []
+    h = {}; def foo(a) a end; foo(**h)  # {} and warning
+    h = {}; def foo(*a) a end; foo(h)   # [{}]
+    h = {}; def foo(a) a end; foo(h)    # {}
+
+* Above warnings can be suppressed also with {-W:no-deprecated option}[#label-Warning+option].
+
+==== Numbered parameters
+
+* Numbered parameters as default block parameters are introduced. [Feature #4475]
+
+    [1, 2, 10].map { _1.to_s(16) }    #=> ["1", "2", "a"]
+    [[1, 2], [3, 4]].map { _1 + _2 }  #=> [3, 7]
+
+  You can still define a local variable named +_1+ and so on,
+  and that is honored when present, but renders a warning.
+
+    _1 = 0            #=> warning: `_1' is reserved for numbered parameter; consider another name
+    [1].each { p _1 } # prints 0 instead of 1
+
+==== proc/lambda without block is deprecated
+
+* Proc.new and Kernel#proc with no block in a method called with a block will
+  now display a warning.
+
+    def foo
+      proc
+    end
+    foo { puts "Hello" } #=> warning: Capturing the given block using Kernel#proc is deprecated; use `&block` instead
+
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Kernel#lambda with no block in a method called with a block raises an exception.
+
+    def bar
+      lambda
+    end
+    bar { puts "Hello" } #=> tried to create Proc object without a block (ArgumentError)
+
+==== Other miscellaneous changes
+
+* A beginless range is experimentally introduced.  It might be useful
+  in +case+, new call-sequence of the <code>Comparable#clamp</code>,
+  constants and DSLs.  [Feature #14799]
+
+     ary[..3]  # identical to ary[0..3]
+
+     case RUBY_VERSION
+     when ..."2.4" then puts "EOL"
+     # ...
+     end
+
+     age.clamp(..100)
+
+     where(sales: ..100)
+
+* Setting <code>$;</code> to a non-nil value will now display a warning. [Feature #14240]
+  This includes the usage in String#split.
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Setting <code>$,</code> to a non-nil value will now display a warning. [Feature #14240]
+  This includes the usage in Array#join.
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Quoted here-document identifiers must end within the same line.
+
+     <<"EOS
+     " # This had been warned since 2.4; Now it raises a SyntaxError
+     EOS
+
+* The flip-flop syntax deprecation is reverted. [Feature #5400]
+
+* Comment lines can be placed between fluent dot now.
+
+    foo
+      # .bar
+      .baz # => foo.baz
+
+* Calling a private method with a literal +self+ as the receiver
+  is now allowed. [Feature #11297] [Feature #16123]
+
+* Modifier rescue now operates the same for multiple assignment as single
+  assignment. [Bug #8279]
+
+    a, b = raise rescue [1, 2]
+    # Previously parsed as: (a, b = raise) rescue [1, 2]
+    # Now parsed as:         a, b = (raise rescue [1, 2])
+
+* +yield+ in singleton class syntax will now display a warning. This behavior
+  will soon be deprecated. [Feature #15575].
+
+   def foo
+     class << Object.new
+       yield #=> warning: `yield' in class syntax will not be supported from Ruby 3.0. [Feature #15575]
+     end
+   end
+   foo { p :ok }
+
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Argument forwarding by <code>(...)</code> is introduced. [Feature #16253]
+
+    def foo(...)
+      bar(...)
+    end
+
+  All arguments to +foo+ are forwarded to +bar+, including keyword and
+  block arguments.
+  Note that the parentheses are mandatory.  <code>bar ...</code> is parsed
+  as an endless range.
+
+* Access and setting of <code>$SAFE</code> will now always display a warning.
+  <code>$SAFE</code> will become a normal global variable in Ruby 3.0.  [Feature #16131]
+
+* <code>Object#{taint,untaint,trust,untrust}</code> and related functions in the C-API
+  no longer have an effect (all objects are always considered untainted), and will now
+  display a warning in verbose mode. This warning will be disabled even in non-verbose mode in
+  Ruby 3.0, and the methods and C functions will be removed in Ruby 3.2. [Feature #16131]
+
+* Refinements take place at Object#method and Module#instance_method. [Feature #15373]
+
+=== Command line options
+
+==== Warning option
+
+The +-W+ option has been extended with a following +:+, to manage categorized
+warnings.  [Feature #16345] [Feature #16420]
+
+* To suppress deprecation warnings:
+
+    $ ruby -e '$; = ""'
+    -e:1: warning: `$;' is deprecated
+
+    $ ruby -W:no-deprecated -e '$; = //'
+
+* It works with the +RUBYOPT+ environment variable:
+
+    $ RUBYOPT=-W:no-deprecated ruby -e '$; = //'
+
+* To suppress experimental feature warnings:
+
+    $ ruby -e '0 in a'
+    -e:1: warning: Pattern matching is experimental, and the behavior may change in future versions of Ruby!
+
+    $ ruby -W:no-experimental -e '0 in a'
+
+* To suppress both by using +RUBYOPT+, set space separated values:
+
+    $ RUBYOPT='-W:no-deprecated -W:no-experimental' ruby -e '($; = "") in a'
+
+See also Warning in {Core classes updates}[#label-Core+classes+updates+-28outstanding+ones+only-29].
+
+=== Core classes updates (outstanding ones only)
+
+[Array]
+
+  [New methods]
+
+    * Added Array#intersection. [Feature #16155]
+
+    * Added Array#minmax, with a faster implementation than Enumerable#minmax. [Bug #15929]
+
+[Comparable]
+
+  [Modified method]
+
+    * Comparable#clamp now accepts a Range argument. [Feature #14784]
+
+        -1.clamp(0..2) #=> 0
+         1.clamp(0..2) #=> 1
+         3.clamp(0..2) #=> 2
+        # With beginless and endless ranges:
+        -1.clamp(0..)  #=> 0
+         3.clamp(..2)  #=> 2
+
+
+[Complex]
+
+  [New method]
+
+    * Added Complex#<=>.
+      So <code>0 <=> 0i</code> will not raise NoMethodError. [Bug #15857]
+
+[Dir]
+
+  [Modified methods]
+
+    * Dir.glob and Dir.[] no longer allow NUL-separated glob pattern.
+      Use Array instead.  [Feature #14643]
+
+[Encoding]
+
+  [New encoding]
+
+    * Added new encoding CESU-8. [Feature #15931]
+
+[Enumerable]
+
+  [New methods]
+
+    * Added Enumerable#filter_map.  [Feature #15323]
+
+        [1, 2, 3].filter_map {|x| x.odd? ? x.to_s : nil } #=> ["1", "3"]
+
+    * Added Enumerable#tally.  [Feature #11076]
+
+        ["A", "B", "C", "B", "A"].tally #=> {"A"=>2, "B"=>2, "C"=>1}
+
+[Enumerator]
+
+  [New methods]
+
+    * Added Enumerator.produce to generate an Enumerator from any custom
+      data transformation.  [Feature #14781]
+
+        require "date"
+        dates = Enumerator.produce(Date.today, &:succ) #=> infinite sequence of dates
+        dates.detect(&:tuesday?) #=> next Tuesday
+
+    * Added Enumerator::Lazy#eager that generates a non-lazy enumerator
+      from a lazy enumerator.  [Feature #15901]
+
+        a = %w(foo bar baz)
+        e = a.lazy.map {|x| x.upcase }.map {|x| x + "!" }.eager
+        p e.class               #=> Enumerator
+        p e.map {|x| x + "?" }  #=> ["FOO!?", "BAR!?", "BAZ!?"]
+
+    * Added Enumerator::Yielder#to_proc so that a Yielder object
+      can be directly passed to another method as a block
+      argument.  [Feature #15618]
+
+    * Added Enumerator::Lazy#with_index be lazy
+      Previously, Enumerator::Lazy#with_index was not defined, so it
+      picked up the default implementation from Enumerator, which was
+      not lazy.  [Bug #7877]
+
+        ("a"..).lazy.with_index(1) { |it, index| puts "#{index}:#{it}" }.take(3).force
+        # => 1:a
+        #    2:b
+        #    3:c
+
+[Fiber]
+
+  [New method]
+
+    * Added Fiber#raise that behaves like Fiber#resume but raises an
+      exception on the resumed fiber.  [Feature #10344]
+
+[File]
+
+  [New method]
+
+    * Added File.absolute_path? to check whether a path is absolute or
+      not in a portable way. [Feature #15868]
+
+        File.absolute_path?("/foo")   # => true (on *nix)
+        File.absolute_path?("C:/foo") # => true (on Windows)
+        File.absolute_path?("foo")    # => false
+
+  [Modified method]
+
+    * File.extname now returns a dot string for names ending with a dot on
+      non-Windows platforms.  [Bug #15267]
+
+          File.extname("foo.") #=> "."
+
+[FrozenError]
+
+  [New method]
+
+    * Added FrozenError#receiver to return the frozen object on which
+      modification was attempted.  To set this object when raising
+      FrozenError in Ruby code, FrozenError.new accepts a +:receiver+
+      option.  [Feature #15751]
+
+[GC]
+
+  [New method]
+
+    * Added GC.compact method for compacting the heap.
+      This function compacts live objects in the heap so that fewer pages may
+      be used, and the heap may be more CoW (copy-on-write) friendly. [Feature #15626]
+
+      Details on the algorithm and caveats can be found here:
+      https://bugs.ruby-lang.org/issues/15626
+

+
+[Method]
+
+  [Modified method]
+
+    * Method#inspect shows more information. [Feature #14145]
+
+[Module]
+
+  [New methods]
+
+    * Added Module#const_source_location to retrieve the location where a
+      constant is defined.  [Feature #10771]
+
+    * Added Module#ruby2_keywords for marking a method as passing keyword
+      arguments through a regular argument splat, useful when delegating
+      all arguments to another method in a way that can be backwards
+      compatible with older Ruby versions.  [Bug #16154]
+
+  [Modified methods]
+
+    * Module#autoload? now takes an +inherit+ optional argument, like
+      Module#const_defined?.  [Feature #15777]
+
+    * Module#name now always returns a frozen String. The returned String is
+      always the same for a given Module. This change is
+      experimental. [Feature #16150]
+
+[NilClass / TrueClass / FalseClass]
+
+  [Modified methods]
+
+    * NilClass#to_s, TrueClass#to_s, and FalseClass#to_s now always return a
+      frozen String. The returned String is always the same for each of these
+      values. This change is experimental. [Feature #16150]
+
+[ObjectSpace::WeakMap]
+
+  [Modified method]
+
+    * ObjectSpace::WeakMap#[]= now accepts special objects as either key or
+      values.  [Feature #16035]
+
+[Proc]
+
+  [New method]
+
+    * Added Proc#ruby2_keywords for marking the proc as passing keyword
+      arguments through a regular argument splat, useful when delegating
+      all arguments to another method or proc in a way that can be backwards
+      compatible with older Ruby versions.  [Feature #16404]
+
+[Range]
+
+  [New method]
+
+    * Added Range#minmax, with a faster implementation than Enumerable#minmax.
+      It returns a maximum that now corresponds to Range#max. [Bug #15807]
+
+  [Modified method]
+
+    * Range#=== now uses Range#cover? for String arguments, too (in Ruby 2.6, it was
+      changed from Range#include? for all types except strings). [Bug #15449]
+
+
+[RubyVM]
+
+  [Removed method]

+[UnboundMethod]
+
+  [New method]
+
+    * Added UnboundMethod#bind_call method.  [Feature #15955]
+
+      <code>umethod.bind_call(obj, ...)</code> is semantically equivalent
+      to <code>umethod.bind(obj).call(...)</code>.  This idiom is used in
+      some libraries to call a method that is overridden.  The added
+      method does the same without allocation of an intermediate Method
+      object.

+  * Warn open-uri's "open" method at Kernel.
+    Use URI.open instead.  [Misc #15893]
+
+  * The default charset of "text/*" media type is UTF-8 instead of
+    ISO-8859-1.  [Bug #15933]
+
+[OptionParser]
+
+  * Now show "Did you mean?" for unknown options.  [Feature #16256]
+
+    test.rb:
+
+      require "optparse"
+      OptionParser.new do |opts|
+        opts.on("-f", "--foo", "foo") {|v| }
+        opts.on("-b", "--bar", "bar") {|v| }
+        opts.on("-c", "--baz", "baz") {|v| }
+      end.parse!
+
+    example:
+
+      $ ruby test.rb --baa
+      Traceback (most recent call last):
+      test.rb:7:in `<main>': invalid option: --baa (OptionParser::InvalidOption)
+      Did you mean?  baz
+                     bar
+
+[Pathname]
+
+  * Pathname.glob now delegates 3 arguments to Dir.glob
+    to accept +base+ keyword. [Feature #14405]
+
+[Racc]
+
+  * Merge 1.4.15 from upstream repository and added cli of racc.
+
+[Reline]
+
+  * New stdlib that is compatible with the readline stdlib but is
+    implemented in pure Ruby. It also provides a multiline editing mode.
+
+[REXML]
+
+  * Upgrade to 3.2.3.
+    See https://github.com/ruby/rexml/blob/master/NEWS.md.
+
+[RSS]
+
+  * Upgrade to RSS 0.2.8.
+    See https://github.com/ruby/rss/blob/master/NEWS.md.
+
+[RubyGems]
+
+  * Upgrade to RubyGems 3.1.2.
+    * https://github.com/rubygems/rubygems/releases/tag/v3.1.0
+    * https://github.com/rubygems/rubygems/releases/tag/v3.1.1
+    * https://github.com/rubygems/rubygems/releases/tag/v3.1.2
+
+[StringScanner]
+
+  * Upgrade to 1.0.3.
+    See https://github.com/ruby/strscan/blob/master/NEWS.md.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* The following libraries are no longer bundled gems.
+  Install corresponding gems to use these features.
+  * CMath (cmath gem)
+  * Scanf (scanf gem)
+  * Shell (shell gem)
+  * Synchronizer (sync gem)
+  * ThreadsWait (thwait gem)
+  * E2MM (e2mmap gem)
+
+[Proc]
+  * The Proc#to_s format was changed. [Feature #16101]
+
+[Range]
+  * Range#minmax used to iterate on the range to determine the maximum.
+    It now uses the same algorithm as Range#max. In rare cases (e.g.
+    ranges of Floats or Strings), this may yield different results. [Bug #15807]
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* Promote stdlib to default gems
+  * The following default gems were published on rubygems.org
+    * benchmark
+    * cgi
+    * delegate
+    * getoptlong
+    * net-pop
+    * net-smtp
+    * open3
+    * pstore
+    * readline
+    * readline-ext
+    * singleton
+  * The following default gems were only promoted at ruby-core,
+    but not yet published on rubygems.org.
+    * monitor
+    * observer
+    * timeout
+    * tracer
+    * uri
+    * yaml
+* The <tt>did_you_mean</tt> gem has been promoted up to a default gem from a bundled gem
+
+[pathname]
+
+  * Kernel#Pathname when called with a Pathname argument now returns
+    the argument instead of creating a new Pathname. This is more
+    similar to other Kernel methods, but can break code that modifies
+    the return value and expects the argument not to be modified.
+
+[profile.rb, Profiler__]
+
+  * Removed from standard library. It was unmaintained since Ruby 2.0.0.
+
+=== C API updates
+
+* Many <code>*_kw</code> functions have been added for setting whether
+  the final argument being passed should be treated as keywords. You
+  may need to switch to these functions to avoid keyword argument
+  separation warnings, and to ensure correct behavior in Ruby 3.
+
+* The <code>:</code> character in rb_scan_args format string is now
+  treated as keyword arguments. Passing a positional hash instead of
+  keyword arguments will emit a deprecation warning.
+
+* C API declarations with +ANYARGS+ are changed not to use +ANYARGS+.
+  See https://github.com/ruby/ruby/pull/2404
+
+=== Implementation improvements
+
+[Fiber]
+
+  * Allow selecting different coroutine implementations by using
+    +--with-coroutine=+, e.g.
+
+         $ ./configure --with-coroutine=ucontext
+         $ ./configure --with-coroutine=copy
+
+  * Replace previous stack cache with fiber pool cache. The fiber pool
+    allocates many stacks in a single memory region. Stack allocation
+    becomes O(log N) and fiber creation is amortized O(1). Around 10x
+    performance improvement was measured in micro-benchmarks.
+    https://github.com/ruby/ruby/pull/2224
+
+[File]
+  * File.realpath now uses realpath(3) on many platforms, which can
+    significantly improve performance. [Feature #15797]
+
+[Hash]
+  * Change data structure of small Hash objects. [Feature #15602]
+
+[Monitor]
+  * Monitor class is written in C-extension. [Feature #16255]
+
+[Thread]
+
+  * VM stack memory allocation is now combined with native thread stack,
+    improving thread allocation performance and reducing allocation related
+    failures. Around 10x performance improvement was measured in micro-benchmarks.
+
+[JIT]
+
+  * JIT-ed code is recompiled to less-optimized code when an optimization assumption is invalidated.
+
+  * Method inlining is performed when a method is considered as pure.
+    This optimization is still experimental and many methods are NOT considered as pure yet.
+
+  * The default value of +--jit-max-cache+ is changed from 1,000 to 100.
+
+  * The default value of +--jit-min-calls+ is changed from 5 to 10,000.
+
+[RubyVM]
+
+  * Per-call-site method cache, which has been there since around 1.9, was
+    improved: cache hit rate raised from 89% to 94%.
+    See https://github.com/ruby/ruby/pull/2583
+
+[RubyVM::InstructionSequence]
+
+  * RubyVM::InstructionSequence#to_binary method generates compiled binary.
+    The binary size is reduced. [Feature #16163]
+
+=== Miscellaneous changes
+
+* Support for IA64 architecture has been removed. Hardware for testing was
+  difficult to find, native fiber code is difficult to implement, and it added
+  non-trivial complexity to the interpreter. [Feature #15894]
+
+* Require compilers to support C99. [Misc #15347]
+
+  * Details of our dialect: https://bugs.ruby-lang.org/projects/ruby-master/wiki/C99
+
+* Ruby's upstream repository is changed from Subversion to Git.
+
+  * https://git.ruby-lang.org/ruby.git
+
+  * RUBY_REVISION class is changed from Integer to String.
+
+  * RUBY_DESCRIPTION includes Git revision instead of Subversion's one.
+
+* Support built-in methods in Ruby with the <code>_\_builtin_</code> syntax. [Feature #16254]
+
+  Some methods are defined in *.rb (such as trace_point.rb).
+  For example, it is easy to define a method which accepts keyword arguments.

+# NEWS for Ruby 3.0.0
+
+This document is a list of user visible feature changes
+since the **2.7.0** release, except for bug fixes.
+
+Note that each entry is kept to a minimum, see links for details.
+
+## Language changes
+
+* Keyword arguments are now separated from positional arguments.
+  Code that resulted in deprecation warnings in Ruby 2.7 will now
+  result in ArgumentError or different behavior. [[Feature #14183]]
+
+* Procs accepting a single rest argument and keywords are no longer
+  subject to autosplatting.  This now matches the behavior of Procs
+  accepting a single rest argument and no keywords.
+  [[Feature #16166]]
+
+    ```ruby
+    pr = proc{|*a, **kw| [a, kw]}
+
+    pr.call([1])
+    # 2.7 => [[1], {}]
+    # 3.0 => [[[1]], {}]
+
+    pr.call([1, {a: 1}])
+    # 2.7 => [[1], {:a=>1}] # and deprecation warning
+    # 3.0 => [[[1, {:a=>1}]], {}]
+    ```
+
+* Arguments forwarding (`...`) now supports leading arguments.
+  [[Feature #16378]]
+
+    ```ruby
+    def method_missing(meth, ...)
+      send(:"do_#{meth}", ...)
+    end
+    ```
+
+* Pattern matching (`case/in`) is no longer experimental. [[Feature #17260]]
+
+* One-line pattern matching is redesigned.  [EXPERIMENTAL]
+
+    * `=>` is added. It can be used like a rightward assignment.
+      [[Feature #17260]]
+
+        ```ruby
+        0 => a
+        p a #=> 0
+
+        {b: 0, c: 1} => {b:}
+        p b #=> 0
+        ```
+
+    * `in` is changed to return `true` or `false`. [[Feature #17371]]
+
+        ```ruby
+        # version 3.0
+        0 in 1 #=> false
+
+        # version 2.7
+        0 in 1 #=> raise NoMatchingPatternError
+        ```
+
+* Find-pattern is added.  [EXPERIMENTAL]
+  [[Feature #16828]]
+
+    ```ruby
+    case ["a", 1, "b", "c", 2, "d", "e", "f", 3]
+    in [*pre, String => x, String => y, *post]
+      p pre  #=> ["a", 1]
+      p x    #=> "b"
+      p y    #=> "c"
+      p post #=> [2, "d", "e", "f", 3]
+    end
+    ```
+
+* Endless method definition is added.  [EXPERIMENTAL]
+  [[Feature #16746]]
+
+    ```ruby
+    def square(x) = x * x
+    ```
+
+* Interpolated String literals are no longer frozen when
+  `# frozen-string-literal: true` is used. [[Feature #17104]]
+
+* Magic comment `shareable_constant_value` added to freeze constants.
+  See {Magic Comments}[rdoc-ref:syntax/comments.rdoc@Magic+Comments] for more details.
+  [[Feature #17273]]
+
+* A {static analysis}[rdoc-label:label-Static+analysis] foundation is
+  introduced.
+    * {RBS}[rdoc-label:label-RBS] is introduced. It is a type definition
+      language for Ruby programs.
+    * {TypeProf}[rdoc-label:label-TypeProf] is experimentally bundled. It is a
+      type analysis tool for Ruby programs.
+
+* Deprecation warnings are no longer shown by default (since Ruby 2.7.2).
+  Turn them on with `-W:deprecated` (or with `-w` to show other warnings too).
+  [[Feature #16345]]
+
+* `$SAFE` and `$KCODE` are now normal global variables with no special behavior.
+  C-API methods related to `$SAFE` have been removed.
+  [[Feature #16131]] [[Feature #17136]]
+
+* yield in singleton class definitions in methods is now a SyntaxError
+  instead of a warning. yield in a class definition outside of a method
+  is now a SyntaxError instead of a LocalJumpError.  [[Feature #15575]]
+
+* When a class variable is overtaken by the same definition in an
+  ancestor class/module, a RuntimeError is now raised (previously,
+  it only issued a warning in verbose mode).  Additionally, accessing a
+  class variable from the toplevel scope is now a RuntimeError.
+  [[Bug #14541]]
+
+* Assigning to a numbered parameter is now a SyntaxError instead of
+  a warning.
+
+## Command line options
+
+### `--help` option
+
+When the environment variable `RUBY_PAGER` or `PAGER` is present and has
+a non-empty value, and the standard input and output are tty, the `--help`
+option shows the help message via the pager designated by the value.
+[[Feature #16754]]
+
+### `--backtrace-limit` option
+
+The `--backtrace-limit` option limits the maximum length of a backtrace.
+[[Feature #8661]]
+
+## Core classes updates
+
+Outstanding ones only.
+
+* Array
+
+    * The following methods now return Array instances instead of
+      subclass instances when called on subclass instances:
+      [[Bug #6087]]
+
+        * Array#drop
+        * Array#drop_while
+        * Array#flatten
+        * Array#slice!
+        * Array#slice / Array#[]
+        * Array#take
+        * Array#take_while
+        * Array#uniq
+        * Array#*
+
+    * Can be sliced with Enumerator::ArithmeticSequence
+
+        ```ruby
+        dirty_data = ['--', 'data1', '--', 'data2', '--', 'data3']
+        dirty_data[(1..).step(2)] # take each second element
+        # => ["data1", "data2", "data3"]
+        ```
+
+* Binding
+
+    * Binding#eval when called with one argument will use `"(eval)"`
+      for `__FILE__` and `1` for `__LINE__` in the evaluated code.
+      [[Bug #4352]] [[Bug #17419]]
+
+* ConditionVariable
+
+    * ConditionVariable#wait may now invoke the `block`/`unblock` scheduler
+      hooks in a non-blocking context. [[Feature #16786]]
+
+* Dir
+
+    * Dir.glob and Dir.[] now sort the results by default, and
+      accept the `sort:` keyword option.  [[Feature #8709]]
+
+* ENV
+
+    * ENV.except has been added, which returns a hash excluding the
+      given keys and their values.  [[Feature #15822]]
+
+    * Windows: Read ENV names and values as UTF-8 encoded Strings
+      [[Feature #12650]]
+
+* Encoding
+
+    * Added new encoding IBM720.  [[Feature #16233]]
+
+    * Changed default for Encoding.default_external to UTF-8 on Windows
+      [[Feature #16604]]
+
+* Fiber
+
+    * Fiber.new(blocking: true/false) allows you to create non-blocking
+      execution contexts. [[Feature #16786]]
+
+    * Fiber#blocking? tells whether the fiber is non-blocking. [[Feature #16786]]
+
+    * Fiber#backtrace and Fiber#backtrace_locations provide per-fiber backtrace.
+      [[Feature #16815]]
+
+    * The limitation of Fiber#transfer is relaxed. [[Bug #17221]]
+
+* GC
+
+    * GC.auto_compact= and GC.auto_compact have been added to control
+      when compaction runs.  Setting `auto_compact=` to `true` will cause
+      compaction to occur during major collections.  At the moment,
+      compaction adds significant overhead to major collections, so please
+      test first!  [[Feature #17176]]
+
+* Hash
+
+    * Hash#transform_keys and Hash#transform_keys! now accept a hash that maps
+      keys to new keys.  [[Feature #16274]]
+
+    * Hash#except has been added, which returns a hash excluding the
+      given keys and their values.  [[Feature #15822]]
+
+* IO
+
+    * IO#nonblock? now defaults to `true`. [[Feature #16786]]
+
+    * IO#wait_readable, IO#wait_writable, IO#read, IO#write and other
+      related methods (e.g. IO#puts, IO#gets) may invoke the scheduler hook
+      `#io_wait(io, events, timeout)` in a non-blocking execution context.
+      [[Feature #16786]]
+
+* Kernel
+
+    * Kernel#clone when called with the `freeze: false` keyword will call
+      `#initialize_clone` with the `freeze: false` keyword.
+      [[Bug #14266]]
+
+    * Kernel#clone when called with the `freeze: true` keyword will call
+      `#initialize_clone` with the `freeze: true` keyword, and will
+      return a frozen copy even if the receiver is unfrozen.
+      [[Feature #16175]]
+
+    * Kernel#eval when called with two arguments will use `"(eval)"`
+      for `__FILE__` and `1` for `__LINE__` in the evaluated code.
+      [[Bug #4352]]
+
+    * Kernel#lambda now warns if called without a literal block.
+      [[Feature #15973]]
+
+    * Kernel.sleep invokes the scheduler hook `#kernel_sleep(...)` in a
+      non-blocking execution context. [[Feature #16786]]
+
+* Module
+
+    * Module#include and Module#prepend now affect classes and modules
+      that have already included or prepended the receiver, mirroring the
+      behavior if the arguments were included in the receiver before
+      the other modules and classes included or prepended the receiver.
+      [[Feature #9573]]
+
+        ```ruby
+        class C; end
+        module M1; end
+        module M2; end
+        C.include M1
+        M1.include M2
+        p C.ancestors #=> [C, M1, M2, Object, Kernel, BasicObject]
+        ```
+
+    * Module#public, Module#protected, Module#private, Module#public_class_method,
+      Module#private_class_method, toplevel "private" and "public" methods
+      now accept single array argument with a list of method names. [[Feature #17314]]
+
+    * Module#attr_accessor, Module#attr_reader, Module#attr_writer and Module#attr
+      methods now return an array of defined method names as symbols.
+      [[Feature #17314]]
+
+    * Module#alias_method now returns the defined alias as a symbol.
+      [[Feature #17314]]
+
+* Mutex
+
+    * `Mutex` is now acquired per-`Fiber` instead of per-`Thread`. This change
+      should be compatible for essentially all usages and avoids blocking when
+      using a scheduler. [[Feature #16792]]
+
+* Proc
+
+    * Proc#== and Proc#eql? are now defined and will return true for
+      separate Proc instances if the procs were created from the same block.
+      [[Feature #14267]]
+
+* Queue / SizedQueue
+
+    * Queue#pop, SizedQueue#push and related methods may now invoke the
+      `block`/`unblock` scheduler hooks in a non-blocking context.
+      [[Feature #16786]]
+
+* Ractor
+
+    * New class added to enable parallel execution. See rdoc-ref:ractor.md for
+      more details.
+
+* Random
+
+    * `Random::DEFAULT` now refers to the `Random` class instead of being a `Random` instance,
+      so it can work with `Ractor`.
+      [[Feature #17322]]
+
+    * `Random::DEFAULT` is deprecated since its value is now confusing and it is no longer global,
+      use `Kernel.rand`/`Random.rand` directly, or create a `Random` instance with `Random.new` instead.
+      [[Feature #17351]]
+
+
+* String
+
+    * The following methods now return or yield String instances
+      instead of subclass instances when called on subclass instances:
+      [[Bug #10845]]
+
+        * String#*
+        * String#capitalize
+        * String#center
+        * String#chomp
+        * String#chop
+        * String#delete
+        * String#delete_prefix
+        * String#delete_suffix
+        * String#downcase
+        * String#dump
+        * String#each_char
+        * String#each_grapheme_cluster
+        * String#each_line
+        * String#gsub
+        * String#ljust
+        * String#lstrip
+        * String#partition
+        * String#reverse
+        * String#rjust
+        * String#rpartition
+        * String#rstrip
+        * String#scrub
+        * String#slice!
+        * String#slice / String#[]
+        * String#split
+        * String#squeeze
+        * String#strip
+        * String#sub
+        * String#succ / String#next
+        * String#swapcase
+        * String#tr
+        * String#tr_s
+        * String#upcase
+
+* Symbol
+
+    * Symbol#to_proc now returns a lambda Proc.  [[Feature #16260]]
+
+    * Symbol#name has been added, which returns the name of the symbol
+      if it is named.  The returned string is frozen.  [[Feature #16150]]
+
+* Fiber
+
+    * Introduce Fiber.set_scheduler for intercepting blocking operations and
+      Fiber.scheduler for accessing the current scheduler. See
+      rdoc-ref:fiber.md for more details about what operations are supported and
+      how to implement the scheduler hooks. [[Feature #16786]]
+
+    * Fiber.blocking? tells whether the current execution context is
+      blocking. [[Feature #16786]]
+
+    * Thread#join invokes the scheduler hooks `block`/`unblock` in a
+      non-blocking execution context. [[Feature #16786]]
+
+* Thread
+
+    * Thread.ignore_deadlock accessor has been added for disabling the
+      default deadlock detection, allowing the use of signal handlers to
+      break deadlock. [[Bug #13768]]
+
+* Warning
+
+    * Warning#warn now supports a category keyword argument.
+      [[Feature #17122]]

+
+    * Net::SMTP.start arguments are keyword arguments.
+
+    * TLS should not check the host name by default.

+
+## Compatibility issues
+
+Excluding feature bug fixes.
+
+* Regexp literals and all Range objects are frozen. [[Feature #8948]] [[Feature #16377]] [[Feature #15504]]
+
+    ```ruby
+    /foo/.frozen? #=> true
+    (42...).frozen? # => true
+    ```
+
+* EXPERIMENTAL: Hash#each consistently yields a 2-element array. [[Bug #12706]]
+
+    * Now `{ a: 1 }.each(&->(k, v) { })` raises an ArgumentError
+      due to lambda's arity check.
+
+* When writing to STDOUT redirected to a closed pipe, no broken pipe
+  error message will be shown now.  [[Feature #14413]]
+
+* `TRUE`/`FALSE`/`NIL` constants are no longer defined.
+
+* Integer#zero? overrides Numeric#zero? for optimization.  [[Misc #16961]]
+
+* Enumerable#grep and Enumerable#grep_v when passed a Regexp and no block no longer modify
+  Regexp.last_match. [[Bug #17030]]
+
+* Requiring 'open-uri' no longer redefines `Kernel#open`.
+  Call `URI.open` directly or `use URI#open` instead. [[Misc #15893]]
+
+* SortedSet has been removed for dependency and performance reasons.
+
+## Stdlib compatibility issues
+
+* Default gems
+
+    * The following libraries are promoted to default gems from stdlib.
+
+        * English
+        * abbrev
+        * base64
+        * drb
+        * debug
+        * erb
+        * find
+        * net-ftp
+        * net-http
+        * net-imap
+        * net-protocol
+        * open-uri
+        * optparse
+        * pp
+        * prettyprint
+        * resolv-replace
+        * resolv
+        * rinda
+        * set
+        * securerandom
+        * shellwords
+        * tempfile
+        * tmpdir
+        * time
+        * tsort
+        * un
+        * weakref
+
+    * The following extensions are promoted to default gems from stdlib.
+
+        * digest
+        * io-nonblock
+        * io-wait
+        * nkf
+        * pathname
+        * syslog
+        * win32ole
+
+* Bundled gems
+
+    * net-telnet and xmlrpc have been removed from the bundled gems.
+      If you are interested in maintaining them, please comment on
+      your plan to https://github.com/ruby/xmlrpc
+      or https://github.com/ruby/net-telnet.
+
+* SDBM has been removed from the Ruby standard library. [[Bug #8446]]
+
+    * The issues of sdbm will be handled at https://github.com/ruby/sdbm
+
+* WEBrick has been removed from the Ruby standard library. [[Feature #17303]]
+
+    * The issues of WEBrick will be handled at https://github.com/ruby/webrick
+
+## C API updates
+
+* C API functions related to `$SAFE` have been removed.
+  [[Feature #16131]]
+
+* C API header file `ruby/ruby.h` was split. [[GH-2991]]
+
+    This should have no impact on extension libraries,
+    but users might experience slow compilations.
+
+* Memory view interface [EXPERIMENTAL]
+
+    * The memory view interface is a C-API set to exchange a raw memory area,
+      such as a numeric array or a bitmap image, between extension libraries.
+      The extension libraries can share also the metadata of the memory area
+      that consists of the shape, the element format, and so on.
+      Using these kinds of metadata, the extension libraries can share even
+      a multidimensional array appropriately.
+      This feature is designed by referring to Python's buffer protocol.
+      [[Feature #13767]] [[Feature #14722]]
+
+* Ractor related C APIs are introduced (experimental) in "include/ruby/ractor.h".
+
+## Implementation improvements
+
+* New method cache mechanism for Ractor. [[Feature #16614]]
+
+    * Inline method caches pointed from ISeq can be accessed by multiple Ractors
+      in parallel and synchronization is needed even for method caches. However,
+      such synchronization can be overhead so introducing new inline method cache
+      mechanisms, (1) Disposable inline method cache (2) per-Class method cache
+      and (3) new invalidation mechanism. (1) can avoid per-method call
+      synchronization because it only uses atomic operations.
+      See the ticket for more details.
+
+* The number of hashes allocated when using a keyword splat in
+  a method call has been reduced to a maximum of 1, and passing
+  a keyword splat to a method that accepts specific keywords
+  does not allocate a hash.
+
+* `super` is optimized when the same type of method is called in the previous call
+  if it's not refinements or an attr reader or writer.
+
+### JIT
+
+* Performance improvements of JIT-ed code
+
+    * Microarchitectural optimizations
+
+        * Native functions shared by multiple methods are deduplicated on JIT compaction.
+
+        * Decrease code size of hot paths by some optimizations and partitioning cold paths.
+
+    * Instance variables
+
+        * Eliminate some redundant checks.
+
+        * Skip checking a class and a object multiple times in a method when possible.
+
+        * Optimize accesses in some core classes like Hash and their subclasses.
+
+    * Method inlining support for some C methods
+
+        * `Kernel`: `#class`, `#frozen?`
+
+        * `Integer`: `#-@`, `#~`, `#abs`, `#bit_length`, `#even?`, `#integer?`, `#magnitude`,
+          `#odd?`, `#ord`, `#to_i`, `#to_int`, `#zero?`
+
+        * `Struct`: reader methods for 10th or later members
+
+    * Constant references are inlined.
+
+    * Always generate appropriate code for `==`, `nil?`, and `!` calls depending on
+      a receiver class.
+
+    * Reduce the number of PC accesses on branches and method returns.
+
+    * Optimize C method calls a little.
+
+* Compilation process improvements
+
+    * It does not keep temporary files in /tmp anymore.
+
+    * Throttle GC and compaction of JIT-ed code.
+
+    * Avoid GC-ing JIT-ed code when not necessary.
+
+    * GC-ing JIT-ed code is executed in a background thread.
+
+    * Reduce the number of locks between Ruby and JIT threads.
+
+## Static analysis
+
+### RBS
+
+* RBS is a new language for type definition of Ruby programs.
+  It allows writing types of classes and modules with advanced
+  types including union types, overloading, generics, and
+  _interface types_ for duck typing.
+
+* Ruby ships with type definitions for core/stdlib classes.
+
+* `rbs` gem is bundled to load and process RBS files.
+
+### TypeProf
+
+* TypeProf is a type analysis tool for Ruby code based on abstract interpretation.
+
+    * It reads non-annotated Ruby code, tries inferring its type signature, and prints
+      the analysis result in RBS format.
+
+    * Though it supports only a subset of the Ruby language yet, we will continuously
+      improve the coverage of language features, analysis performance, and usability.
+
+```ruby
+# test.rb
+def foo(x)
+  if x > 10
+    x.to_s
+  else
+    nil
+  end
+end
+
+foo(42)
+```
+
+```
+$ typeprof test.rb
+# Classes
+class Object
+  def foo : (Integer) -> String?
+end
+```
+
+## Miscellaneous changes
+
+* Methods using `ruby2_keywords` will no longer keep empty keyword
+  splats, those are now removed just as they are for methods not
+  using `ruby2_keywords`.
+
+* When an exception is caught in the default handler, the error
+  message and backtrace are printed in order from the innermost.
+  [[Feature #8661]]
+
+* Accessing an uninitialized instance variable no longer emits a
+  warning in verbose mode. [[Feature #17055]]

+# NEWS for Ruby 3.1.0
+
+This document is a list of user-visible feature changes
+since the **3.0.0** release, except for bug fixes.
+
+Note that each entry is kept to a minimum, see links for details.
+
+## Language changes
+
+*   The block argument can now be anonymous if the block will
+    only be passed to another method. [[Feature #11256]]
+
+    ```ruby
+    def foo(&)
+      bar(&)
+    end
+    ```
+
+*   Pin operator now takes an expression. [[Feature #17411]]
+
+    ```ruby
+    Prime.each_cons(2).lazy.find_all{_1 in [n, ^(n + 2)]}.take(3).to_a
+    #=> [[3, 5], [5, 7], [11, 13]]
+    ```
+
+*   Pin operator now supports instance, class, and global variables.
+    [[Feature #17724]]
+
+    ```ruby
+    @n = 5
+    Prime.each_cons(2).lazy.find{_1 in [n, ^@n]}
+    #=> [3, 5]
+    ```
+
+*   One-line pattern matching is no longer experimental.
+
+*   Parentheses can be omitted in one-line pattern matching.
+    [[Feature #16182]]
+
+    ```ruby
+    [0, 1] => _, x
+    {y: 2} => y:
+    x #=> 1
+    y #=> 2
+    ```
+
+*   Multiple assignment evaluation order has been made consistent with
+    single assignment evaluation order.  With single assignment, Ruby
+    uses a left-to-right evaluation order.  With this code:
+
+    ```ruby
+    foo[0] = bar
+    ```
+
+    The following evaluation order is used:
+
+    1. `foo`
+    2. `bar`
+    3. `[]=` called on the result of `foo`
+
+    In Ruby before 3.1.0, multiple assignment did not follow this
+    evaluation order.  With this code:
+
+    ```ruby
+    foo[0], bar.baz = a, b
+    ```
+
+    Versions of Ruby before 3.1.0 would evaluate in the following
+    order
+
+    1. `a`
+    2. `b`
+    3. `foo`
+    4. `[]=` called on the result of `foo`
+    5. `bar`
+    6. `baz=` called on the result of `bar`
+
+    Starting in Ruby 3.1.0, the evaluation order is now consistent with
+    single assignment, with the left-hand side being evaluated before
+    the right-hand side:
+
+    1. `foo`
+    2. `bar`
+    3. `a`
+    4. `b`
+    5. `[]=` called on the result of `foo`
+    6. `baz=` called on the result of `bar`
+
+    [[Bug #4443]]
+
+*   Values in Hash literals and keyword arguments can be omitted.
+    [[Feature #14579]]
+
+    For example,
+
+    * `{x:, y:}` is a syntax sugar of `{x: x, y: y}`.
+    * `foo(x:, y:)` is a syntax sugar of `foo(x: x, y: y)`.
+
+    Constant names, local variable names, and method names are allowed as
+    key names.  Note that a reserved word is considered as a local
+    variable or method name even if it's a pseudo variable name such as
+    `self`.
+
+*   Non main-Ractors can get instance variables (ivars) of classes/modules
+    if ivars refer to shareable objects.
+    [[Feature #17592]]
+
+*   A command syntax is allowed in endless method definitions, i.e.,
+    you can now write `def foo = puts "Hello"`.
+    Note that `private def foo = puts "Hello"` does not parse.
+    [[Feature #17398]]
+
+## Command line options
+
+* `--disable-gems` is now explicitly declared as "just for debugging".
+  Never use it in any real-world codebase.
+  [[Feature #17684]]
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Array
+
+    * Array#intersect? is added. [[Feature #15198]]
+
+* Class
+
+    *   Class#subclasses, which returns an array of classes
+        directly inheriting from the receiver, not
+        including singleton classes.
+        [[Feature #18273]]
+
+        ```ruby
+        class A; end
+        class B < A; end
+        class C < B; end
+        class D < A; end
+        A.subclasses    #=> [D, B]
+        B.subclasses    #=> [C]
+        C.subclasses    #=> []
+        ```
+
+* Enumerable
+
+    *   Enumerable#compact is added. [[Feature #17312]]
+
+    *   Enumerable#tally now accepts an optional hash to count. [[Feature #17744]]
+
+    *   Enumerable#each_cons and each_slice to return a receiver. [[GH-1509]]
+
+        ```ruby
+        [1, 2, 3].each_cons(2){}
+        # 3.0 => nil
+        # 3.1 => [1, 2, 3]
+
+        [1, 2, 3].each_slice(2){}
+        # 3.0 => nil
+        # 3.1 => [1, 2, 3]
+        ```
+
+* Enumerator::Lazy
+
+    *   Enumerator::Lazy#compact is added. [[Feature #17312]]
+
+* File
+
+    *   File.dirname now accepts an optional argument for the level to
+        strip path components. [[Feature #12194]]
+
+* GC
+
+    *   "GC.measure_total_time = true" enables the measurement of GC.
+        Measurement can introduce overhead. It is enabled by default.
+        GC.measure_total_time returns the current setting.
+        GC.stat[:time] or GC.stat(:time) returns measured time
+        in milli-seconds. [[[Feature #10917]]]
+
+    *   GC.total_time returns measured time in nano-seconds. [[[Feature #10917]]]
+
+* Integer
+
+    *   Integer.try_convert is added. [[Feature #15211]]
+
+* Kernel
+
+    *   Kernel#load now accepts a module as the second argument,
+        and will load the file using the given module as the
+        top-level module. [[Feature #6210]]
+
+* Marshal
+
+    *   Marshal.load now accepts a `freeze: true` option.
+        All returned objects are frozen except for `Class` and
+        `Module` instances. Strings are deduplicated. [[Feature #18148]]
+
+* MatchData
+
+    *   MatchData#match is added [[Feature #18172]]
+
+    *   MatchData#match_length is added [[Feature #18172]]
+
+* Method / UnboundMethod
+
+    *   Method#public?, Method#private?, Method#protected?,
+        UnboundMethod#public?, UnboundMethod#private?,
+        UnboundMethod#protected? have been added. [[Feature #11689]]
+
+* Module
+
+    *   Module#prepend now modifies the ancestor chain if the receiver
+        already includes the argument. Module#prepend still does not
+        modify the ancestor chain if the receiver has already prepended
+        the argument. [[Bug #17423]]
+
+    *   Module#private, #public, #protected, and #module_function will
+        now return their arguments.  If a single argument is given, it
+        is returned. If no arguments are given, nil is returned.  If
+        multiple arguments are given, they are returned as an array.
+        [[Feature #12495]]
+
+* Process
+
+    *   Process.\_fork is added. This is a core method for fork(2).
+        Do not call this method directly; it is called by existing
+        fork methods: Kernel.#fork, Process.fork, and IO.popen("-").
+        Application monitoring libraries can overwrite this method to
+        hook fork events. [[Feature #17795]]
+
+* Struct
+
+    *   Passing only keyword arguments to Struct#initialize is warned.
+        You need to use a Hash literal to set a Hash to a first member.
+        [[Feature #16806]]
+
+    *   StructClass#keyword_init? is added [[Feature #18008]]
+
+* String
+
+    *   Update Unicode version to 13.0.0 [[Feature #17750]]
+        and Emoji version to 13.0 [[Feature #18029]]
+
+    *   String#unpack and String#unpack1 now accept an `offset:` keyword
+        argument to start the unpacking after an arbitrary number of bytes
+        have been skipped. If `offset` is outside of the string bounds
+        `ArgumentError` is raised. [[Feature #18254]]
+
+* Thread
+
+    *   Thread#native_thread_id is added. [[Feature #17853]]
+
+* Thread::Backtrace
+
+    *   Thread::Backtrace.limit, which returns the value to limit backtrace
+        length set by `--backtrace-limit` command line option, is added.
+        [[Feature #17479]]
+
+* Thread::Queue
+
+    *   Thread::Queue.new now accepts an Enumerable of initial values.
+        [[Feature #17327]]
+
+* Time
+
+    *   Time.new now accepts optional `in:` keyword argument for the
+        timezone, as well as `Time.at` and `Time.now`, so that is now
+        you can omit minor arguments to `Time.new`. [[Feature #17485]]
+
+        ```ruby
+        Time.new(2021, 12, 25, in: "+07:00")
+        #=> 2021-12-25 00:00:00 +0700
+        ```
+
+        At the same time, time component strings are converted to
+        integers more strictly now.
+
+        ```ruby
+        Time.new(2021, 12, 25, "+07:30")
+        #=> invalid value for Integer(): "+07:30" (ArgumentError)
+        ```
+
+        Ruby 3.0 or earlier returned probably unexpected result
+        `2021-12-25 07:00:00`, not `2021-12-25 07:30:00` nor
+        `2021-12-25 00:00:00 +07:30`.
+
+    *   Time#strftime supports RFC 3339 UTC for unknown offset local
+        time, `-0000`, as `%-z`. [[Feature #17544]]
+
+* TracePoint
+
+    *   TracePoint.allow_reentry is added to allow reenter while TracePoint
+        callback.
+        [[Feature #15912]]
+
+* $LOAD_PATH
+
+    *   $LOAD_PATH.resolve_feature_path does not raise. [[Feature #16043]]
+
+* Fiber Scheduler
+
+    *   Add support for `Addrinfo.getaddrinfo` using `address_resolve` hook.
+        [[Feature #17370]]
+
+    *   Introduce non-blocking `Timeout.timeout` using `timeout_after` hook.
+        [[Feature #17470]]
+
+    *   Introduce new scheduler hooks `io_read` and `io_write` along with a
+        low level `IO::Buffer` for zero-copy read/write. [[Feature #18020]]
+
+    *   IO hooks `io_wait`, `io_read`, `io_write`, receive the original IO object
+        where possible. [[Bug #18003]]
+
+    *   Make `Monitor` fiber-safe. [[Bug #17827]]
+
+    *   Replace copy coroutine with pthread implementation. [[Feature #18015]]
+
+* Refinement
+
+    *   New class which represents a module created by Module#refine.
+        `include` and `prepend` are deprecated, and `import_methods` is added
+        instead. [[Bug #17429]]

+
+* Random::Formatter is moved to random/formatter.rb, so that you can
+  use `Random#hex`, `Random#base64`, and so on without SecureRandom.
+  [[Feature #18190]]
+
+## Compatibility issues
+
+Note: Excluding feature bug fixes.
+
+* `rb_io_wait_readable`, `rb_io_wait_writable` and `rb_wait_for_single_fd` are
+  deprecated in favour of `rb_io_maybe_wait_readable`,
+  `rb_io_maybe_wait_writable` and `rb_io_maybe_wait` respectively.
+  `rb_thread_wait_fd` and `rb_thread_fd_writable` are deprecated. [[Bug #18003]]
+
+## Stdlib compatibility issues
+
+* `ERB#initialize` warns `safe_level` and later arguments even without -w.
+  [[Feature #14256]]
+
+* `lib/debug.rb` is replaced with `debug.gem`
+
+* `Kernel#pp` in `lib/pp.rb` uses the width of `IO#winsize` by default.
+  This means that the output width is automatically changed depending on
+  your terminal size. [[Feature #12913]]
+
+* Psych 4.0 changes `Psych.load` as `safe_load` by the default.
+  You may need to use Psych 3.3.2 for migrating to this behavior.
+  [[Bug #17866]]
+
+## C API updates
+
+* Documented. [[GH-4815]]
+
+* `rb_gc_force_recycle` is deprecated and has been changed to a no-op.
+  [[Feature #18290]]
+
+## Implementation improvements
+
+* Inline cache mechanism is introduced for reading class variables.
+  [[Feature #17763]]
+
+* `instance_eval` and `instance_exec` now only allocate a singleton class when
+  required, avoiding extra objects and improving performance. [[GH-5146]]
+
+* The performance of `Struct` accessors is improved. [[GH-5131]]
+
+* `mandatory_only?` builtin special form to improve performance on
+  builtin methods. [[GH-5112]]
+
+* Experimental feature Variable Width Allocation in the garbage collector.
+  This feature is turned off by default and can be enabled by compiling Ruby
+  with flag `USE_RVARGC=1` set. [[Feature #18045]] [[Feature #18239]]
+
+## JIT
+
+* Rename Ruby 3.0's `--jit` to `--mjit`, and alias `--jit` to `--yjit`
+  on non-Windows x86-64 platforms and to `--mjit` on others.
+
+### MJIT
+
+* The default `--mjit-max-cache` is changed from 100 to 10000.
+
+* JIT-ed code is no longer cancelled when a TracePoint for class events
+  is enabled.
+
+* The JIT compiler no longer skips compilation of methods longer than
+  1000 instructions.
+
+* `--mjit-verbose` and `--mjit-warning` output "JIT cancel" when JIT-ed
+  code is disabled because TracePoint or GC.compact is used.
+
+### YJIT: New experimental in-process JIT compiler
+
+New JIT compiler available as an experimental feature. [[Feature #18229]]
+
+See [this blog post](https://shopify.engineering/yjit-just-in-time-compiler-cruby
+) introducing the project.
+
+* Disabled by default, use `--yjit` command-line option to enable YJIT.
+
+* Performance improvements on benchmarks based on real-world software,
+  up to 22% on railsbench, 39% on liquid-render.
+
+* Fast warm-up times.
+
+* Limited to Unix-like x86-64 platforms for now.
+
+## Static analysis
+
+### RBS
+
+*   Generics type parameters can be bounded ([PR](https://github.com/ruby/rbs/pull/844)).
+
+    ```rbs
+    # `T` must be compatible with the `_Output` interface.
+    # `PrettyPrint[String]` is ok, but `PrettyPrint[Integer]` is a type error.
+    class PrettyPrint[T < _Output]
+      interface _Output
+        def <<: (String) -> void
+      end
+
+      attr_reader output: T
+
+      def initialize: (T output) -> void
+    end
+    ```
+
+*   Type aliases can be generic. ([PR](https://github.com/ruby/rbs/pull/823))
+
+    ```rbs
+    # Defines a generic type `list`.
+    type list[T] = [ T, list[T] ]
+                 | nil
+
+    type str_list = list[String]
+    type int_list = list[Integer]
+    ```
+
+* [rbs collection](https://github.com/ruby/rbs/blob/cdd6a3a896001e25bd1feda3eab7f470bae935c1/docs/collection.md) has been introduced to manage gems’ RBSs.
+
+* Many signatures for built-in and standard libraries have been added/updated.
+
+* It includes many bug fixes and performance improvements too.
+
+See the [CHANGELOG.md](https://github.com/ruby/rbs/blob/cdd6a3a896001e25bd1feda3eab7f470bae935c1/CHANGELOG.md) for more information.
+
+### TypeProf
+
+* [Experimental IDE support](https://github.com/ruby/typeprof/blob/ca15c5dae9bd62668463165f8409bd66ce7de223/doc/ide.md) has been implemented.
+* Many bug fixes and performance improvements since Ruby 3.0.0.
+
+## Debugger
+
+* A new debugger [debug.gem](https://github.com/ruby/debug) is bundled.
+  debug.gem is a fast debugger implementation, and it provides many features
+  like remote debugging, colorful REPL, IDE (VSCode) integration, and more.
+  It replaces `lib/debug.rb` standard library.
+
+* `rdbg` command is also installed into `bin/` directory to start and control
+  debugging execution.
+
+## error_highlight
+
+A built-in gem called error_highlight has been introduced.
+It shows fine-grained error locations in the backtrace.
+
+Example: `title = json[:article][:title]`
+
+If `json` is nil, it shows:
+
+```
+$ ruby test.rb
+test.rb:2:in `<main>': undefined method `[]' for nil:NilClass (NoMethodError)
+
+title = json[:article][:title]
+            ^^^^^^^^^^
+```
+
+If `json[:article]` returns nil, it shows:
+
+```
+$ ruby test.rb
+test.rb:2:in `<main>': undefined method `[]' for nil:NilClass (NoMethodError)
+
+title = json[:article][:title]
+                      ^^^^^^^^
+```
+
+This feature is enabled by default.
+You can disable it by using a command-line option `--disable-error_highlight`.
+See [the repository](https://github.com/ruby/error_highlight) in detail.
+
+## IRB Autocomplete and Document Display
+
+The IRB now has an autocomplete feature, where you can just type in the code, and the completion candidates dialog will appear. You can use Tab and Shift+Tab to move up and down.
+
+If documents are installed when you select a completion candidate, the documentation dialog will appear next to the completion candidates dialog, showing part of the content. You can read the full document by pressing Alt+d.
+
+## Miscellaneous changes
+
+* lib/objspace/trace.rb is added, which is a tool for tracing the object
+  allocation. Just by requiring this file, tracing is started *immediately*.
+  Just by `Kernel#p`, you can investigate where an object was created.
+  Note that just requiring this file brings a large performance overhead.
+  This is only for debugging purposes. Do not use this in production.
+  [[Feature #17762]]
+
+* Now exceptions raised in finalizers will be printed to `STDERR`, unless
+  `$VERBOSE` is `nil`.  [[Feature #17798]]
+
+* `ruby -run -e httpd` displays URLs to access.  [[Feature #17847]]
+
+* Add `ruby -run -e colorize` to colorize Ruby code using
+  `IRB::Color.colorize_code`.

+== Binary Searching
+
+A few Ruby methods support binary searching in a collection:
+
+Array#bsearch:: Returns an element selected via a binary search
+                as determined by a given block.
+Array#bsearch_index:: Returns the index of an element selected via a binary search
+                      as determined by a given block.
+Range#bsearch:: Returns an element selected via a binary search
+                as determined by a given block.
+
+Each of these methods returns an enumerator if no block is given.
+
+Given a block, each of these methods returns an element (or element index) from +self+
+as determined by a binary search.
+The search finds an element of +self+ which meets
+the given condition in <tt>O(log n)</tt> operations, where +n+ is the count of elements.
++self+ should be sorted, but this is not checked.
+
+There are two search modes:
+
+Find-minimum mode:: method +bsearch+ returns the first element for which
+                    the block returns +true+;
+                    the block must return +true+ or +false+.
+Find-any mode:: method +bsearch+ some element, if any, for which
+                the block returns zero.
+                the block must return a numeric value.
+
+The block should not mix the modes by sometimes returning +true+ or +false+
+and other times returning a numeric value, but this is not checked.
+
+<b>Find-Minimum Mode</b>
+
+In find-minimum mode, the block must return +true+ or +false+.
+The further requirement (though not checked) is that
+there are no indexes +i+ and +j+ such that:
+
+- <tt>0 <= i < j <= self.size</tt>.
+- The block returns +true+ for <tt>self[i]</tt> and +false+ for <tt>self[j]</tt>.
+
+Less formally: the block is such that all +false+-evaluating elements
+precede all +true+-evaluating elements.
+
+In find-minimum mode, method +bsearch+ returns the first element
+for which the block returns +true+.
+
+Examples:
+
+  a = [0, 4, 7, 10, 12]
+  a.bsearch {|x| x >= 4 } # => 4
+  a.bsearch {|x| x >= 6 } # => 7
+  a.bsearch {|x| x >= -1 } # => 0
+  a.bsearch {|x| x >= 100 } # => nil
+
+  r = (0...a.size)
+  r.bsearch {|i| a[i] >= 4 } #=> 1
+  r.bsearch {|i| a[i] >= 6 } #=> 2
+  r.bsearch {|i| a[i] >= 8 } #=> 3
+  r.bsearch {|i| a[i] >= 100 } #=> nil
+  r = (0.0...Float::INFINITY)
+  r.bsearch {|x| Math.log(x) >= 0 } #=> 1.0
+
+These blocks make sense in find-minimum mode:
+
+  a = [0, 4, 7, 10, 12]
+  a.map {|x| x >= 4 } # => [false, true, true, true, true]
+  a.map {|x| x >= 6 } # => [false, false, true, true, true]
+  a.map {|x| x >= -1 } # => [true, true, true, true, true]
+  a.map {|x| x >= 100 } # => [false, false, false, false, false]
+
+This would not make sense:
+
+  a.map {|x| x == 7 } # => [false, false, true, false, false]
+
+<b>Find-Any Mode</b>
+
+In find-any mode, the block must return a numeric value.
+The further requirement (though not checked) is that
+there are no indexes +i+ and +j+ such that:
+
+- <tt>0 <= i < j <= self.size</tt>.
+- The block returns a negative value for <tt>self[i]</tt>
+  and a positive value for <tt>self[j]</tt>.
+- The block returns a negative value for <tt>self[i]</tt> and zero <tt>self[j]</tt>.
+- The block returns zero for <tt>self[i]</tt> and a positive value for <tt>self[j]</tt>.
+
+Less formally: the block is such that:
+
+- All positive-evaluating elements precede all zero-evaluating elements.
+- All positive-evaluating elements precede all negative-evaluating elements.
+- All zero-evaluating elements precede all negative-evaluating elements.
+
+In find-any mode, method +bsearch+ returns some element
+for which the block returns zero, or +nil+ if no such element is found.
+
+Examples:
+
+  a = [0, 4, 7, 10, 12]
+  a.bsearch {|element| 7 <=> element } # => 7
+  a.bsearch {|element| -1 <=> element } # => nil
+  a.bsearch {|element| 5 <=> element } # => nil
+  a.bsearch {|element| 15 <=> element } # => nil
+
+  a = [0, 100, 100, 100, 200]
+  r = (0..4)
+  r.bsearch {|i| 100 - a[i] } #=> 1, 2 or 3
+  r.bsearch {|i| 300 - a[i] } #=> nil
+  r.bsearch {|i|  50 - a[i] } #=> nil
+
+These blocks make sense in find-any mode:
+
+  a = [0, 4, 7, 10, 12]
+  a.map {|element| 7 <=> element } # => [1, 1, 0, -1, -1]
+  a.map {|element| -1 <=> element } # => [-1, -1, -1, -1, -1]
+  a.map {|element| 5 <=> element } # => [1, 1, -1, -1, -1]
+  a.map {|element| 15 <=> element } # => [1, 1, 1, 1, 1]
+
+This would not make sense:
+
+  a.map {|element| element <=> 7 } # => [-1, -1, 0, 1, 1]

+= Bug Triaging Guide
+
+This guide discusses recommendations for triaging bugs in Ruby's bug tracker.
+
+== Bugs with Reproducible Examples
+
+These are the best bug reports.  First, consider whether the bug reported is
+actually an issue or if it is expected Ruby behavior.  If it is expected Ruby
+behavior, update the issue with why the behavior is expected, and set the
+status to Rejected.
+
+If the bug reported appears to be an actual bug, try reproducing the bug with
+the master branch.  If you are not able to reproduce the issue on the master
+branch, try reproducing it on the latest version for the branch the bug was
+reported on.  If you cannot reproduce the issue in either case, update
+the issue stating you cannot reproduce the issue, ask the reporter if they
+can reproduce the issue with either the master branch or a later release,
+and set the status to Feedback.
+
+If you can reproduce the example with the master branch, try to figure out
+what is causing the issue.  If you feel comfortable, try working on a
+patch for the issue, update the issue, and attach the patch.  Try to figure
+out which committer should be assigned to the issue, and set them as the
+assignee, and set the status to Assigned.
+
+If you cannot reproduce the example with the master branch, but can reproduce
+the issue on the latest version for the branch, then it is likely the bug has
+already been fixed, but it has not been backported yet.  Try to determine
+which commit fixed it, and update the issue noting that the issue has been
+fixed but not yet backported.  If the Ruby version is in the security
+maintenance phase or no longer supported, change the status to Closed. This
+change can be made without adding a note to avoid spamming the mailing list.
+
+For issues that may require backwards incompatible changes or may benefit from
+general committer attention or discussion, consider adding them as agenda
+items for the next committer meeting (https://bugs.ruby-lang.org/issues/14770).
+
+== Crash Bugs Without Reproducers
+
+Many bugs reported have little more than a crash report, often with no way to
+reproduce the issue.  These bugs are difficult to triage as they often do not
+contain enough information.
+
+For these bugs, if the Ruby version is the master branch or is the latest
+release for the branch and the branch is in normal maintenance phase, look at
+the backtrace and see if you can determine what could be causing the issue.
+If you can guess what could be causing the issue, see if you can put together
+a reproducible example (this is in general quite difficult).  If you cannot
+guess what could be causing the issue, or cannot put together a reproducible
+example yourself, please ask the reporter to provide a reproducible example,
+and change the status to Feedback.
+
+If the Ruby version is no longer current (e.g. 2.5.0 when the latest version
+on the Ruby 2.5 branch is 2.5.5), add a note to the issue asking the reporter
+to try the latest Ruby version for the branch and report back, and change the
+status to Feedback.  If the Ruby version is in the security maintenance phase
+or no longer supported, change the status to Closed. This change can be made
+without adding a note.
+
+== Crash Bugs With 3rd Party C Extensions
+
+If the crash happens inside a 3rd party C extension, try to figure out inside
+which C extension it happens, and add a note to the issue to report the
+issue to that C extension, and set the status to Third Party's Issue.
+
+== Non-Bug reports
+
+Any issues in the bug tracker that are not reports of problems should have
+the tracker changed from Bug to either Feature (new features or performance
+improvements) or Misc. This change can be made without adding a note.
+
+== Stale Issues
+
+There are many issues that are stale, with no updates in months or even years.
+For stale issues in Feedback state, where the feedback has not been received,
+you can change the status to Closed without adding a note.  For stale issues
+in Assigned state, you can reach out to the assignee and see if they can update
+the issue.  If the assignee is no longer an active committer, remove them
+as the assignee and change the status to Open.

+== Case Mapping
+
+Some string-oriented methods use case mapping.
+
+In String:
+
+- String#capitalize
+- String#capitalize!
+- String#casecmp
+- String#casecmp?
+- String#downcase
+- String#downcase!
+- String#swapcase
+- String#swapcase!
+- String#upcase
+- String#upcase!
+
+In Symbol:
+
+- Symbol#capitalize
+- Symbol#casecmp
+- Symbol#casecmp?
+- Symbol#downcase
+- Symbol#swapcase
+- Symbol#upcase
+
+=== Default Case Mapping
+
+By default, all of these methods use full Unicode case mapping,
+which is suitable for most languages.
+See {Section 3.13 (Default Case Algorithms) of the Unicode standard}[https://www.unicode.org/versions/latest/ch03.pdf].
+
+Non-ASCII case mapping and folding are supported for UTF-8,
+UTF-16BE/LE, UTF-32BE/LE, and ISO-8859-1~16 Strings/Symbols.
+
+Context-dependent case mapping as described in
+{Table 3-17 (Context Specification for Casing) of the Unicode standard}[https://www.unicode.org/versions/latest/ch03.pdf]
+is currently not supported.
+
+In most cases, case conversions of a string have the same number of characters.
+There are exceptions (see also +:fold+ below):
+
+  s = "\u00DF" # => "ß"
+  s.upcase     # => "SS"
+  s = "\u0149" # => "ŉ"
+  s.upcase     # => "ʼN"
+
+Case mapping may also depend on locale (see also +:turkic+ below):
+
+  s = "\u0049"        # => "I"
+  s.downcase          # => "i" # Dot above.
+  s.downcase(:turkic) # => "ı" # No dot above.
+
+Case changes may not be reversible:
+
+  s = 'Hello World!' # => "Hello World!"
+  s.downcase         # => "hello world!"
+  s.downcase.upcase  # => "HELLO WORLD!" # Different from original s.
+
+Case changing methods may not maintain Unicode normalization.
+See String#unicode_normalize).
+
+=== Options for Case Mapping
+
+Except for +casecmp+ and +casecmp?+,
+each of the case-mapping methods listed above
+accepts optional arguments, <tt>*options</tt>.
+
+The arguments may be:
+
+- +:ascii+ only.
+- +:fold+ only.
+- +:turkic+ or +:lithuanian+ or both.
+
+The options:
+
+- +:ascii+:
+  ASCII-only mapping:
+  uppercase letters ('A'..'Z') are mapped to lowercase letters ('a'..'z);
+  other characters are not changed
+
+    s = "Foo \u00D8 \u00F8 Bar" # => "Foo Ø ø Bar"
+    s.upcase                    # => "FOO Ø Ø BAR"
+    s.downcase                  # => "foo ø ø bar"
+    s.upcase(:ascii)            # => "FOO Ø ø BAR"
+    s.downcase(:ascii)          # => "foo Ø ø bar"
+
+- +:turkic+:
+  Full Unicode case mapping, adapted for the Turkic languages
+  that distinguish dotted and dotless I, for example Turkish and Azeri.
+
+    s = 'Türkiye'       # => "Türkiye"
+    s.upcase            # => "TÜRKIYE"
+    s.upcase(:turkic)   # => "TÜRKİYE" # Dot above.
+
+    s = 'TÜRKIYE'       # => "TÜRKIYE"
+    s.downcase          # => "türkiye"
+    s.downcase(:turkic) # => "türkıye" # No dot above.
+
+- +:lithuanian+:
+  Not yet implemented.
+
+- +:fold+ (available only for String#downcase, String#downcase!,
+  and Symbol#downcase):
+  Unicode case folding,
+  which is more far-reaching than Unicode case mapping.
+
+    s = "\u00DF"      # => "ß"
+    s.downcase        # => "ß"
+    s.downcase(:fold) # => "ss"
+    s.upcase          # => "SS"
+
+    s = "\uFB04"      # => "ﬄ"
+    s.downcase        # => "ﬄ"
+    s.upcase          # => "FFL"
+    s.downcase(:fold) # => "ffl"

+== Character Selectors
+
+=== Character Selector
+
+A _character_ _selector_ is a string argument accepted by certain Ruby methods.
+Each of these instance methods accepts one or more character selectors:
+
+- String#tr(selector, replacements): returns a new string.
+- String#tr!(selector, replacements): returns +self+ or +nil+.
+- String#tr_s(selector, replacements): returns a new string.
+- String#tr_s!(selector, replacements): returns +self+ or +nil+.
+- String#count(*selectors): returns the count of the specified characters.
+- String#delete(*selectors): returns a new string.
+- String#delete!(*selectors): returns +self+ or +nil+.
+- String#squeeze(*selectors): returns a new string.
+- String#squeeze!(*selectors): returns +self+ or +nil+.
+
+A character selector identifies zero or more characters in +self+
+that are to be operands for the method.
+
+In this section, we illustrate using method String#delete(selector),
+which deletes the selected characters.
+
+In the simplest case, the characters selected are exactly those
+contained in the selector itself:
+
+  'abracadabra'.delete('a')   # => "brcdbr"
+  'abracadabra'.delete('ab')  # => "rcdr"
+  'abracadabra'.delete('abc') # => "rdr"
+  '0123456789'.delete('258')  # => "0134679"
+  '!@#$%&*()_+'.delete('+&#') # => "!@$%*()_"
+  'тест'.delete('т')          # => "ес"
+  'こんにちは'.delete('に')     # => "こんちは"
+
+Note that order and repetitions do not matter:
+
+  'abracadabra'.delete('dcab') # => "rr"
+  'abracadabra'.delete('aaaa') # => "brcdbr"
+
+In a character selector, these three characters get special treatment:
+
+- A leading caret (<tt>'^'</tt>) functions as a "not" operator
+  for the characters to its right:
+
+    'abracadabra'.delete('^bc') # => "bcb"
+    '0123456789'.delete('^852') # => "258"
+
+- A hyphen (<tt>'-'</tt>) between two other characters
+  defines a range of characters instead of a plain string of characters:
+
+    'abracadabra'.delete('a-d') # => "rr"
+    '0123456789'.delete('4-7')  # => "012389"
+    '!@#$%&*()_+'.delete(' -/') # => "@^_"
+
+    # May contain more than one range.
+    'abracadabra'.delete('a-cq-t') # => "d"
+
+    # Ranges may be mixed with plain characters.
+    '0123456789'.delete('67-950-23') # => "4"
+
+    # Ranges may be mixed with negations.
+    'abracadabra'.delete('^a-c') # => "abacaaba"
+
+- A backslash (<tt>'\'</tt>) acts as an escape for a caret, a hyphen,
+  or another backslash:
+
+    'abracadabra^'.delete('\^bc')   # => "araadara"
+    'abracadabra-'.delete('a\-d')   # => "brcbr"
+    "hello\r\nworld".delete("\r")   # => "hello\nworld"
+    "hello\r\nworld".delete("\\r")  # => "hello\r\nwold"
+    "hello\r\nworld".delete("\\\r") # => "hello\nworld"
+
+=== Multiple Character Selectors
+
+These instance methods accept multiple character selectors:
+
+- String#count(*selectors): returns the count of the specified characters.
+- String#delete(*selectors): returns a new string.
+- String#delete!(*selectors): returns +self+ or +nil+.
+- String#squeeze(*selectors): returns a new string.
+- String#squeeze!(*selectors): returns +self+ or +nil+.
+
+In effect, the given selectors are formed into a single selector
+consisting of only those characters common to _all_ of the given selectors.
+
+All forms of selectors may be used, including negations, ranges, and escapes.
+
+Each of these pairs of method calls is equivalent:
+
+  s.delete('abcde', 'dcbfg')
+  s.delete('bcd')
+
+  s.delete('^abc', '^def')
+  s.delete('^abcdef')
+
+  s.delete('a-e', 'c-g')
+  s.delete('cde')

+== Command Injection
+
+Some Ruby core methods accept string data
+that includes text to be executed as a system command.
+
+They should not be called with unknown or unsanitized commands.
+
+These methods include:
+
+- Kernel.system
+- {\`command` (backtick method)}[rdoc-ref:Kernel#`]

+# Building Ruby
+
+## Quick start guide
+
+1. Install the prerequisite dependencies for building the CRuby interpreter:
+
+    * C compiler
+    * autoconf - 2.67 or later
+    * bison - 3.0 or later
+    * gperf - 3.0.3 or later
+    * ruby - 2.7 or later
+
+2. Install optional, recommended dependencies:
+
+    * OpenSSL/LibreSSL
+    * readline/editline (libedit)
+    * zlib
+    * libffi
+    * libyaml
+    * libexecinfo (FreeBSD)
+    * rustc - 1.58.0 or later (if you wish to build [YJIT](/doc/yjit/yjit.md))
+
+3. Checkout the CRuby source code:
+
+    ```
+    git clone https://github.com/ruby/ruby.git
+    ```
+
+4. Generate the configure file:
+
+    ```
+    ./autogen.sh
+    ```
+
+5. Create a `build` directory outside of the source directory:
+
+    ```
+    mkdir build && cd build
+    ```
+
+    While it's not necessary to build in a separate directory, it's good practice to do so.
+
+6. We'll install Ruby in `~/.rubies/ruby-master`, so create the directory:
+
+    ```
+    mkdir ~/.rubies
+    ```
+
+7. Run configure:
+
+    ```
+    ../configure --prefix="${HOME}/.rubies/ruby-master"
+    ```
+
+    - If you are frequently building Ruby, add the `--disable-install-doc` flag to not build documentation which will speed up the build process.
+
+8. Build Ruby:
+
+    ```
+    make install
+    ```
+
+    - If you're on macOS and installed \OpenSSL through Homebrew, you may encounter failure to build \OpenSSL that look like this:
+
+        ```
+        openssl:
+            Could not be configured. It will not be installed.
+            ruby/ext/openssl/extconf.rb: OpenSSL library could not be found. You might want to use --with-openssl-dir=<dir> option to specify the prefix where OpenSSL is installed.
+            Check ext/openssl/mkmf.log for more details.
+        ```
+
+        Adding `--with-openssl-dir=$(brew --prefix openssl)` to the list of options passed to configure may solve the issue.
+
+        Remember to delete your `build` directory and start again from the configure step.
+
+9. [Run tests](testing_ruby.md) to confirm your build succeeded.
+
+### Unexplainable Build Errors
+
+If you are having unexplainable build errors, after saving all your work, try running `git clean -xfd` in the source root to remove all git ignored local files. If you are working from a source directory that's been updated several times, you may have temporary build artifacts from previous releases which can cause build failures.
+
+## More details
+
+If you're interested in continuing development on Ruby, here are more details
+about Ruby's build to help out.
+
+### Running make scripts in parallel
+
+In GNU make and BSD make implementations, to run a specific make script in parallel, pass the flag `-j<number of processes>`. For instance,
+to run tests on 8 processes, use:
+
+```
+make test-all -j8
+```
+
+We can also set `MAKEFLAGS` to run _all_ `make` commands in parallel.
+
+Having the right `--jobs` flag will ensure all processors are utilized when building software projects. To do this effectively, you can set `MAKEFLAGS` in your shell configuration/profile:
+
+``` shell
+# On macOS with Fish shell:
+export MAKEFLAGS="--jobs "(sysctl -n hw.ncpu)
+
+# On macOS with Bash/ZSH shell:
+export MAKEFLAGS="--jobs $(sysctl -n hw.ncpu)"
+
+# On Linux with Fish shell:
+export MAKEFLAGS="--jobs "(nproc)
+
+# On Linux with Bash/ZSH shell:
+export MAKEFLAGS="--jobs $(nproc)"
+```
+
+### Miniruby vs Ruby
+
+Miniruby is a version of Ruby which has no external dependencies and lacks certain features.
+It can be useful in Ruby development because it allows for faster build times. Miniruby is
+built before Ruby. A functional Miniruby is required to build Ruby. To build Miniruby:
+
+```
+make miniruby
+```
+
+## Debugging
+
+You can use either lldb or gdb for debugging. Before debugging, you need to create a `test.rb`
+with the Ruby script you'd like to run. You can use the following make targets:
+
+* `make run`: Runs `test.rb` using Miniruby
+* `make lldb`: Runs `test.rb` using Miniruby in lldb
+* `make gdb`: Runs `test.rb` using Miniruby in gdb
+* `make runruby`: Runs `test.rb` using Ruby
+* `make lldb-ruby`: Runs `test.rb` using Ruby in lldb
+* `make gdb-ruby`: Runs `test.rb` using Ruby in gdb
+
+### Building with Address Sanitizer
+
+Using the address sanitizer is a great way to detect memory issues.
+
+``` shell
+./autogen.sh
+mkdir build && cd build
+export ASAN_OPTIONS="halt_on_error=0:use_sigaltstack=0:detect_leaks=0"
+../configure cppflags="-fsanitize=address -fno-omit-frame-pointer" optflags=-O0 LDFLAGS="-fsanitize=address -fno-omit-frame-pointer"
+make
+```
+
+On Linux it is important to specify `-O0` when debugging. This is especially true for ASAN which sometimes works incorrectly at higher optimisation levels.
+
+## How to measure coverage of C and Ruby code
+
+You need to be able to use gcc (gcov) and lcov visualizer.
+
+```
+./autogen.sh
+./configure --enable-gcov
+make
+make update-coverage
+rm -f test-coverage.dat
+make test-all COVERAGE=true
+make lcov
+open lcov-out/index.html
+```
+
+If you need only C code coverage, you can remove `COVERAGE=true` from the above process.
+You can also use `gcov` command directly to get per-file coverage.
+
+If you need only Ruby code coverage, you can remove `--enable-gcov`.
+Note that `test-coverage.dat` accumulates all runs of `make test-all`.
+Make sure that you remove the file if you want to measure one test run.
+
+You can see the coverage result of CI: https://rubyci.org/coverage

+This guide discusses recommendations for documenting
+classes, modules, and methods
+in the Ruby core and in the Ruby standard library.
+
+## Generating documentation
+
+Most Ruby documentation lives in the source files and is written in
+[RDoc format](rdoc-ref:RDoc::Markup).
+
+Some pages live under the `doc` folder and can be written in either
+`.rdoc` or `.md` format, determined by the file extension.
+
+To generate the output of documentation changes in HTML in the
+`{build folder}/.ext/html` directory, run the following inside your
+build directory:
+
+```sh
+make html
+```
+
+Then you can preview your changes by opening
+`{build folder}/.ext/html/index.html` file in your browser.
+
+
+## Goal
+
+The goal of Ruby documentation is to impart the most important
+and relevant in the shortest time.
+The reader should be able to quickly understand the usefulness
+of the subject code and how to use it.
+
+Providing too little information is bad, but providing unimportant
+information or unnecessary examples is not good either.
+Use your judgment about what the user needs to know.
+
+## General Guidelines
+
+- Keep in mind that the reader may not be fluent in \English.
+- Write short declarative or imperative sentences.
+- Group sentences into (ideally short) paragraphs,
+  each covering a single topic.
+- Organize material with [headers](rdoc-ref:RDoc::Markup@Headers).
+- Refer to authoritative and relevant sources using
+  [links](rdoc-ref:RDoc::Markup@Links).
+- Use simple verb tenses: simple present, simple past, simple future.
+- Use simple sentence structure, not compound or complex structure.
+- Avoid:
+    - Excessive comma-separated phrases;
+      consider a [list](rdoc-ref:RDoc::Markup@Simple+Lists).
+    - Idioms and culture-specific references.
+    - Overuse of headers.
+    - Using US-ASCII-incompatible characters in C source files;
+      see [Characters](#label-Characters) below.
+
+### Characters
+
+Use only US-ASCII-compatible characters in a C source file.
+(If you use other characters, the Ruby CI will gently let you know.)
+
+If want to put ASCII-incompatible characters into the documentation
+for a C-coded class, module, or method, there are workarounds
+involving new files `doc/*.rdoc`:
+
+- For class `Foo` (defined in file `foo.c`),
+  create file `doc/foo.rdoc`, declare `class Foo; end`,
+  and place the class documentation above that declaration:
+
+    ```ruby
+    # Documentation for class Foo goes here.
+    class Foo; end
+    ```
+
+- Similarly, for module `Bar` (defined in file `bar.c`,
+  create file `doc/bar.rdoc`, declare `module Bar; end`,
+  and place the module documentation above that declaration:
+
+    ```ruby
+    # Documentation for module Bar goes here.
+    module Bar; end
+    ```
+
+- For a method, things are different.
+  Documenting a method as above disables the "click to toggle source" feature
+  in the rendered documentation.
+
+    Therefore it's best to use file inclusion:
+
+    - Retain the `call-seq` in the C code.
+    - Use file inclusion (`:include:`) to include text from an .rdoc file.
+
+    Example:
+
+    ```
+    /*
+     *  call-seq:
+     *    each_byte {|byte| ... } -> self
+     *    each_byte               -> enumerator
+     *
+     *  :include: doc/string/each_byte.rdoc
+     *
+     */
+    ```
+
+### \RDoc
+
+Ruby is documented using RDoc.
+For information on \RDoc syntax and features, see the
+[RDoc Markup Reference](rdoc-ref:RDoc::Markup@RDoc+Markup+Reference).
+
+### Output from `irb`
+
+For code examples, consider using interactive Ruby,
+[irb](https://ruby-doc.org/stdlib/libdoc/irb/rdoc/IRB.html).
+
+For a code example that includes `irb` output,
+consider aligning `# => ...` in successive lines.
+Alignment may sometimes aid readability:
+
+```ruby
+a = [1, 2, 3] #=> [1, 2, 3]
+a.shuffle!    #=> [2, 3, 1]
+a             #=> [2, 3, 1]
+```
+
+### Headers
+
+Organize a long discussion with [headers](rdoc-ref:RDoc::Markup@Headers).
+
+### Blank Lines
+
+A blank line begins a new paragraph.
+
+A [code block](rdoc-ref:RDoc::Markup@Paragraphs+and+Verbatim)
+or [list](rdoc-ref:RDoc::Markup@Simple+Lists)
+should be preceded by and followed by a blank line.
+This is unnecessary for the HTML output, but helps in the `ri` output.
+
+### \Method Names
+
+For a method name in text:
+
+- For a method in the current class or module,
+  use a double-colon for a singleton method,
+  or a hash mark for an instance method:
+  <tt>::bar</tt>, <tt>#baz</tt>.
+- Otherwise, include the class or module name
+  and use a dot for a singleton method,
+  or a hash mark for an instance method:
+  <tt>Foo.bar</tt>, <tt>Foo#baz</tt>.
+
+### Auto-Linking
+
+In general, \RDoc's auto-linking should not be suppressed.
+For example, we should write `Array`, not `\Array`.
+
+We might consider whether to suppress when:
+
+- The word in question does not refer to a Ruby entity
+  (e.g., some uses of _Class_ or _English_).
+- The reference is to the current class document
+  (e.g., _Array_ in the documentation for class `Array`).
+- The same reference is repeated many times
+  (e.g., _RDoc_ on this page).
+
+### HTML Tags
+
+In general, avoid using HTML tags (even in formats where it's allowed)
+because `ri` (the Ruby Interactive reference tool)
+may not render them properly.
+
+### Tables
+
+In particular, avoid building tables with HTML tags
+(<tt><table></tt>, etc.).
+
+Alternatives are:
+
+- The GFM (GitHub Flavored Markdown) table extension,
+  which is enabled by default. See
+  {GFM tables extension}[https://github.github.com/gfm/#tables-extension-].
+
+- A {verbatim text block}[rdoc-ref:RDoc::MarkupReference@Verbatim+Text+Blocks],
+  using spaces and punctuation to format the text.
+  Note that {text markup}[rdoc-ref:RDoc::MarkupReference@Text+Markup]
+  will not be honored.
+
+## Documenting Classes and Modules
+
+The general structure of the class or module documentation should be:
+
+- Synopsis
+- Common uses, with examples
+- "What's Here" summary (optional)
+
+### Synopsis
+
+The synopsis is a short description of what the class or module does
+and why the reader might want to use it.
+Avoid details in the synopsis.
+
+### Common Uses
+
+Show common uses of the class or module.
+Depending on the class or module, this section may vary greatly
+in both length and complexity.
+
+### What's Here Summary
+
+The documentation for a class or module may include a "What's Here" section.
+
+Guidelines:
+
+- The section title is `What's Here`.
+- Consider listing the parent class and any included modules; consider
+  [links](rdoc-ref:RDoc::Markup@Links)
+  to their "What's Here" sections if those exist.
+- List methods as a bullet list:
+
+    - Begin each item with the method name, followed by a colon
+      and a short description.
+    - If the method has aliases, mention them in parentheses before the colon
+      (and do not list the aliases separately).
+    - Check the rendered documentation to determine whether \RDoc has recognized
+      the method and linked to it;  if not, manually insert a
+      [link](rdoc-ref:RDoc::Markup@Links).
+
+- If there are numerous entries, consider grouping them into subsections with headers.
+- If there are more than a few such subsections,
+  consider adding a table of contents just below the main section title.
+
+## Documenting Methods
+
+### General Structure
+
+The general structure of the method documentation should be:
+
+- Calling sequence (for methods written in C).
+- Synopsis (short description).
+- Details and examples.
+- Argument description (if necessary).
+- Corner cases and exceptions.
+- Aliases.
+- Related methods (optional).
+
+### Calling Sequence (for methods written in C)
+
+For methods written in Ruby, \RDoc documents the calling sequence automatically.
+
+For methods written in C, \RDoc cannot determine what arguments
+the method accepts, so those need to be documented using \RDoc directive
+[`call-seq:`](rdoc-ref:RDoc::Markup@Method+arguments).
+
+For a singleton method, use the form:
+
+```
+class_name.method_name(method_args) {|block_args| ... } -> return_type
+```
+
+Example:
+
+```
+*  call-seq:
+*    Hash.new(default_value = nil) -> new_hash
+*    Hash.new {|hash, key| ... } -> new_hash
+```
+
+For an instance method, use the form
+(omitting any prefix, just as RDoc does for a Ruby-coded method):
+
+```
+method_name(method_args) {|block_args| ... } -> return_type
+```
+For example, in Array, use:
+
+```
+*  call-seq:
+*    count -> integer
+*    count(obj) -> integer
+*    count {|element| ... } -> integer
+```
+
+```
+* call-seq:
+*    <=> other -> -1, 0, 1, or nil
+```
+
+Arguments:
+
+- If the method does not accept arguments, omit the parentheses.
+- If the method accepts optional arguments:
+
+    - Separate each argument name and its default value with ` = `
+      (equal-sign with surrounding spaces).
+    - If the method has the same behavior with either an omitted
+      or an explicit argument, use a `call-seq` with optional arguments.
+      For example, use:
+
+        ```
+        respond_to?(symbol, include_all = false) -> true or false
+        ```
+
+    - If the behavior is different with an omitted or an explicit argument,
+      use a `call-seq` with separate lines.
+      For example, in Enumerable, use:
+
+        ```
+        *    max    -> element
+        *    max(n) -> array
+        ```
+
+Block:
+
+- If the method does not accept a block, omit the block.
+- If the method accepts a block, the `call-seq` should have `{|args| ... }`,
+  not `{|args| block }` or `{|args| code }`.
+
+Return types:
+
+- If the method can return multiple different types,
+  separate the types with "or" and, if necessary, commas.
+- If the method can return multiple types, use +object+.
+- If the method returns the receiver, use +self+.
+- If the method returns an object of the same class,
+  prefix `new_` if an only if the object is not  +self+;
+  example: `new_array`.
+
+Aliases:
+
+- Omit aliases from the `call-seq`, but mention them near the end (see below).
+
+### Synopsis
+
+The synopsis comes next, and is a short description of what the
+method does and why you would want to use it.  Ideally, this
+is a single sentence, but for more complex methods it may require
+an entire paragraph.
+
+For `Array#count`, the synopsis is:
+
+```
+Returns a count of specified elements.
+```
+
+This is great as it is short and descriptive.  Avoid documenting
+too much in the synopsis, stick to the most important information
+for the benefit of the reader.
+
+### Details and Examples
+
+Most non-trivial methods benefit from examples, as well as details
+beyond what is given in the synopsis.  In the details and examples
+section, you can document how the method handles different types
+of arguments, and provides examples on proper usage.  In this
+section, focus on how to use the method properly, not on how the
+method handles improper arguments or corner cases.
+
+Not every behavior of a method requires an example.  If the method
+is documented to return `self`, you don't need to provide an example
+showing the return value is the same as the receiver.  If the method
+is documented to return `nil`, you don't need to provide an example
+showing that it returns `nil`.  If the details mention that for a
+certain argument type, an empty array is returned, you don't need
+to provide an example for that.
+
+Only add an example if it provides the user additional information,
+do not add an example if it provides the same information given
+in the synopsis or details.  The purpose of examples is not to prove
+what the details are stating.
+
+### Argument Description (if necessary)
+
+For methods that require arguments, if not obvious and not explicitly
+mentioned in the details or implicitly shown in the examples, you can
+provide details about the types of arguments supported.  When discussing
+the types of arguments, use simple language even if less-precise, such
+as "level must be an integer", not "level must be an Integer-convertible
+object".  The vast majority of use will be with the expected type, not an
+argument that is explicitly convertible to the expected type, and
+documenting the difference is not important.
+
+For methods that take blocks, it can be useful to document the type of
+argument passed if it is not obvious, not explicitly mentioned in the
+details, and not implicitly shown in the examples.
+
+If there is more than one argument or block argument, use a
+[labeled list](rdoc-ref:RDoc::Markup@Labeled+Lists).
+
+### Corner Cases and Exceptions
+
+For corner cases of methods, such as atypical usage, briefly mention
+the behavior, but do not provide any examples.
+
+Only document exceptions raised if they are not obvious.  For example,
+if you have stated earlier than an argument type must be an integer,
+you do not need to document that a `TypeError` is raised if a non-integer
+is passed.  Do not provide examples of exceptions being raised unless
+that is a common case, such as `Hash#fetch` raising a `KeyError`.
+
+### Aliases
+
+Mention aliases in the form
+
+```
+// Array#find_index is an alias for Array#index.
+```
+
+### Related Methods (optional)
+
+In some cases, it is useful to document which methods are related to
+the current method.  For example, documentation for `Hash#[]` might
+mention `Hash#fetch` as a related method, and `Hash#merge` might mention
+`Hash#merge!` as a related method.
+
+- Consider which methods may be related
+  to the current method, and if you think the reader would benefit it,
+  at the end of the method documentation, add a line starting with
+  "Related: " (e.g. "Related: #fetch.").
+- Don't list more than three related methods.
+  If you think more than three methods are related,
+  list the three you think are most important.
+- Consider adding:
+
+    - A phrase suggesting how the related method is similar to,
+      or different from,the current method.
+      See an example at Time#getutc.
+    - Example code that illustrates the similarities and differences.
+      See examples at Time#ctime, Time#inspect, Time#to_s.
+
+### Methods Accepting Multiple Argument Types
+
+For methods that accept multiple argument types, in some cases it can
+be useful to document the different argument types separately.  It's
+best to use a separate paragraph for each case you are discussing.

+# Contributing a pull request
+
+## Code style
+
+Here are some general rules to follow when writing Ruby and C code for CRuby:
+
+* Do not change code unrelated to your pull request (including style fixes)
+* Indent 4 spaces for C without tabs (tabs are two levels of indentation, equivalent to 8 spaces)
+* Indent 2 spaces for Ruby without tabs
+* ANSI C style for function declarations
+* Follow C99 Standard
+* PascalStyle for class/module names
+* UNDERSCORE_SEPARATED_UPPER_CASE for other constants
+* Abbreviations should be all upper case
+
+## Commit messages
+
+Use the following style for commit messages:
+
+* Use a succinct subject line
+* Include reasoning behind the change in the commit message, focusing on why the change is being made
+* Refer to  issue (such as `Fixes [Bug #1234]` or `Implements [Feature #3456]`), or discussion on the mailing list (such as [ruby-core:12345])
+
+## CI
+
+GitHub actions will run on each pull request.
+
+There is [a CI that runs on master](https://rubyci.org/). It has broad coverage of different systems and architectures, such as Solaris SPARC and macOS.

+# Making Changes To Standard Libraries
+
+Everything in the [lib](https://github.com/ruby/ruby/tree/master/lib) directory is mirrored from a standalone repository into the Ruby repository.
+If you'd like to make contributions to standard libraries, do so in the standalone repositories, and the
+changes will be automatically mirrored into the Ruby repository.
+
+For example, CSV lives in [a separate repository](https://github.com/ruby/csv) and is mirrored into [Ruby](https://github.com/ruby/ruby/tree/master/lib/csv).
+
+## Maintainers
+
+You can find the list of maintainers [here](https://docs.ruby-lang.org/en/master/maintainers_rdoc.html#label-Maintainers).
+
+## Build
+
+First, install its dependencies using:
+
+```
+bundle install
+```
+
+### Libraries with C-extension
+
+If the library has a `/ext` directory, it has C files that you need to compile with:
+
+```
+bundle exec rake compile
+```
+
+## Running tests
+
+All standard libraries use [test-unit](https://github.com/test-unit/test-unit) as the test framework.
+
+To run all tests:
+
+```
+bundle exec rake test
+```
+
+To run a single test file:
+
+```
+bundle exec rake test TEST="test/test_foo.rb"
+```
+
+To run a single test case:
+
+```
+bundle exec rake test TEST="test/test_foo.rb" TESTOPS="--name=/test_mytest/"
+```

+* Please reply to feedback requests. If a bug report doesn't get any feedback,
+  it'll eventually get rejected.
+
+### Reporting website issues
+
+If you're having an issue with the bug tracker or the mailing list, you can
+contact the webmaster, Hiroshi SHIBATA (hsbt@ruby-lang.org).
+
+You can report issues with ruby-lang.org on the
+[repo's issue tracker](https://github.com/ruby/www.ruby-lang.org/issues).
+
+## Requesting features
+
+If there's a new feature that you want to see added to Ruby, you will need to
+write a proposal on [the Redmine issue tracker](https://bugs.ruby-lang.org/projects/ruby-master/issues/new).
+When you open the issue, select `Feature` in the Tracker dropdown.
+
+When writing a proposal, be sure to check for previous discussions on the
+topic and have a solid use case. You should also consider the potential
+compatibility issues that this new feature might raise. Consider making
+your feature into a gem, and if there are enough people who benefit from
+your feature it could help persuade Ruby core.
+
+Here is a template you can use for a feature proposal:
+
+```
+[Abstract]
+  Briefly summarize your feature
+[Background]
+  Describe current behavior
+[Proposal]
+  Describe your feature in detail
+[Use cases]
+  Give specific example uses of your feature
+[Discussion]
+  Describe why this feature is necessary and better than using existing features
+[See also]
+  Link to other related resources (such as implementations in other languages)
+```
+
+## Backport requests
+
+If a bug exists in a released version of Ruby, please report this in the issue.
+Once this bug is fixed, the fix can be backported if deemed necessary. Only Ruby
+committers can request backporting, and backporting is done by the backport manager.
+New patch versions are released at the discretion of the backport manager.
+
+[Ruby versions](https://www.ruby-lang.org/en/downloads/) can be in one of three maintenance states:
+
+* Stable releases: backport any bug fixes
+* Security maintenance: only backport security fixes
+* End of life: no backports, please upgrade your Ruby version
+
+## Add context to existing issues
+
+There are several ways you can help with a bug that aren't directly
+resolving it. These include:
+
+* Verifying or reproducing the existing issue and reporting it
+* Adding more specific reproduction instructions
+* Contributing a failing test as a patch (see ["making changes to Ruby"](making_changes_to_ruby.md))
+* Testing patches that others have submitted (see ["making changes to Ruby"](making_changes_to_ruby.md))

+# Testing Ruby
+
+## Test suites
+
+There are several test suites in the Ruby codebase:
+
+We can run any of the make scripts [in parallel](building_ruby.md#label-Running+make+scripts+in+parallel) to speed them up.
+
+1. [bootstraptest/](https://github.com/ruby/ruby/tree/master/bootstraptest)
+
+    This is a small test suite that runs on Miniruby (see [building Ruby](building_ruby.md#label-Miniruby+vs+Ruby)). We can run it with:
+
+    ```
+    make btest
+    ```
+
+    To run it with logs, we can use:
+
+    ```
+    make btest OPTS=-v
+    ```
+
+    To run individual bootstrap tests, we can either specify a list of filenames or use the `--sets` flag in the variable `BTESTS`:
+
+    ```
+    make btest BTESTS="bootstraptest/test_fork.rb bootstraptest/tes_gc.rb"
+    make btest BTESTS="--sets=fork,gc"
+    ```
+
+    If we want to run the bootstrap test suite on Ruby (not Miniruby), we can use:
+
+    ```
+    make test
+    ```
+
+    To run it with logs, we can use:
+
+    ```
+    make test OPTS=-v
+    ```
+
+    To run a file or directory with GNU make, we can use:
+
+    ```
+    make test/ruby/test_foo.rb
+    make test/ruby/test_foo.rb TESTOPTS="-n /test_bar/"
+    ```
+
+2. [test/](https://github.com/ruby/ruby/tree/master/test)
+
+    This is a more comprehensive test suite that runs on Ruby. We can run it with:
+
+    ```
+    make test-all
+    ```
+
+    We can run a specific test directory in this suite using the `TESTS` option, for example:
+
+    ```
+    make test-all TESTS=test/rubygems
+    ```
+
+    We can run a specific test file in this suite by also using the `TESTS` option, for example:
+
+    ```
+    make test-all TESTS=test/ruby/test_array.rb
+    ```
+
+    We can run a specific test in this suite using the `TESTS` option, specifying
+    first the file name, and then the test name, prefixed with `--name`. For example:
+
+    ```
+    make test-all TESTS="../test/ruby/test_alias.rb --name=/test_alias_with_zsuper_method/"
+    ```
+
+    To run these specs with logs, we can use:
+
+    ```
+    make test-all TESTS=-v
+    ```
+
+    If we would like to run both the `test/` and `bootstraptest/` test suites, we can run
+
+    ```
+    make check
+    ```
+
+3. [spec/ruby](https://github.com/ruby/ruby/tree/master/spec/ruby)
+
+    This is a test suite that exists in [the Ruby spec repository](https://github.com/ruby/spec) and is mirrored into the `spec/ruby` directory in the Ruby repository. It tests the behavior of the Ruby programming language. We can run this using:
+
+    ```
+    make test-spec
+    ```
+
+    To run a specific directory, we can use `MSPECOPT` to specify the directory:
+
+    ```
+    make test-spec MSPECOPT=spec/ruby/core/array
+    ```
+
+    To run a specific file, we can also use `MSPECOPT` to specify the file:
+
+    ```
+    make test-spec MSPECOPT=spec/ruby/core/array/any_spec.rb
+    ```
+
+    To run a specific test, we can use the `--example` flag to match against the test name:
+
+    ```
+    make test-spec MSPECOPT="../spec/ruby/core/array/any_spec.rb --example='is false if the array is empty'"
+    ```
+
+    To run these specs with logs, we can use:
+
+    ```
+    make test-spec MSPECOPT=-Vfs
+    ```
+
+    To run a ruby-spec file or directory with GNU make, we can use
+
+    ```
+    make spec/ruby/core/foo/bar_spec.rb
+    ```
+
+4. [spec/bundler](https://github.com/ruby/ruby/tree/master/spec/bundler)
+
+    The bundler test suite exists in [the RubyGems repository](https://github.com/rubygems/rubygems/tree/master/bundler/spec) and is mirrored into the `spec/bundler` directory in the Ruby repository. We can run this using:
+
+    ```
+    make test-bundler
+    ```
+
+    To run a specific bundler spec file, we can use `BUNDLER_SPECS` as follows:
+
+    ```
+    $ make test-bundler BUNDLER_SPECS=commands/exec_spec.rb

+if any of the following is true:
+* None of those sequences is found.
+* Data is +ARGF+, +STDIN+, +STDOUT+, or +STDERR+.
+* The stream is only available for output.
+
+Obviously, discovery takes a little time. Set manually if speed is important. Also note that IO objects should be opened in binary mode on Windows if this feature will be used as the line-ending translation can cause problems with resetting the document position to where it was before the read ahead.

+
+=== Source and Output Formats
+
+You can use a Unix-style "filter" for \CSV data.
+The filter reads source \CSV data and writes output \CSV data as modified by the filter.
+The input and output \CSV data may be any mixture of \Strings and \IO streams.
+
+==== Filtering \String to \String
+
+You can filter one \String to another, with or without headers.
+
+===== Recipe: Filter \String to \String with Headers
+
+Use class method CSV.filter with option +headers+ to filter a \String to another \String:
+  in_string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  out_string = ''
+  CSV.filter(in_string, out_string, headers: true) do |row|
+    row[0] = row[0].upcase
+    row[1] *= 4
+  end
+  out_string # => "Name,Value\nFOO,0000\nBAR,1111\nBAZ,2222\n"
+
+===== Recipe: Filter \String to \String Without Headers
+
+Use class method CSV.filter without option +headers+ to filter a \String to another \String:
+  in_string = "foo,0\nbar,1\nbaz,2\n"
+  out_string = ''
+  CSV.filter(in_string, out_string) do |row|
+    row[0] = row[0].upcase
+    row[1] *= 4
+  end
+  out_string # => "FOO,0000\nBAR,1111\nBAZ,2222\n"
+
+==== Filtering \String to \IO Stream
+
+You can filter a \String to an \IO stream, with or without headers.
+
+===== Recipe: Filter \String to \IO Stream with Headers
+
+Use class method CSV.filter with option +headers+ to filter a \String to an \IO stream:
+  in_string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  path = 't.csv'
+  File.open(path, 'w') do |out_io|
+    CSV.filter(in_string, out_io, headers: true) do |row|
+      row[0] = row[0].upcase
+      row[1] *= 4
+    end
+  end
+  p File.read(path) # => "Name,Value\nFOO,0000\nBAR,1111\nBAZ,2222\n"
+
+===== Recipe: Filter \String to \IO Stream Without Headers

+  end
+  p File.read(path) # => "FOO,0000\nBAR,1111\nBAZ,2222\n"
+
+==== Filtering \IO Stream to \String
+
+You can filter an \IO stream to a \String, with or without headers.
+
+===== Recipe: Filter \IO Stream to \String with Headers

+
+=== Output Formats
+
+You can generate \CSV output to a \String, to a \File (via its path), or to an \IO stream.
+
+==== Generating to a \String
+
+You can generate \CSV output to a \String, with or without headers.
+
+===== Recipe: Generate to \String with Headers
+
+Use class method CSV.generate with option +headers+ to generate to a \String.
+
+This example uses method CSV#<< to append the rows
+that are to be generated:
+  output_string = CSV.generate('', headers: ['Name', 'Value'], write_headers: true) do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Name,Value\nFoo,0\nBar,1\nBaz,2\n"
+
+===== Recipe: Generate to \String Without Headers
+
+Use class method CSV.generate without option +headers+ to generate to a \String.
+
+This example uses method CSV#<< to append the rows
+that are to be generated:
+  output_string = CSV.generate do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Foo,0\nBar,1\nBaz,2\n"
+
+==== Generating to a \File
+
+You can generate /CSV data to a \File, with or without headers.
+
+===== Recipe: Generate to \File with Headers
+
+Use class method CSV.open with option +headers+ generate to a \File.
+
+This example uses method CSV#<< to append the rows
+that are to be generated:
+  path = 't.csv'
+  CSV.open(path, 'w', headers: ['Name', 'Value'], write_headers: true) do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  p File.read(path) # => "Name,Value\nFoo,0\nBar,1\nBaz,2\n"
+
+===== Recipe: Generate to \File Without Headers
+
+Use class method CSV.open without option +headers+ to generate to a \File.
+

+
+==== Generating to an \IO Stream
+
+You can generate \CSV data to an \IO stream, with or without headers.
+
+==== Recipe: Generate to \IO Stream with Headers
+
+Use class method CSV.new with option +headers+ to generate \CSV data to an \IO stream:
+  path = 't.csv'
+  File.open(path, 'w') do |file|
+    csv = CSV.new(file, headers: ['Name', 'Value'], write_headers: true)
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]

+
+Use class method CSV.new without option +headers+ to generate \CSV data to an \IO stream:
+  path = 't.csv'
+  File.open(path, 'w') do |file|
+    csv = CSV.new(file)
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  p File.read(path) # => "Foo,0\nBar,1\nBaz,2\n"
+
+=== Converting Fields
+
+You can use _write_ _converters_ to convert fields when generating \CSV.
+
+==== Recipe: Filter Generated Field Strings
+
+Use option <tt>:write_converters</tt> and a custom converter to convert field values when generating \CSV.
+
+This example defines and uses a custom write converter to strip whitespace from generated fields:
+  strip_converter = proc {|field| field.respond_to?(:strip) ? field.strip : field }
+  output_string = CSV.generate(write_converters: strip_converter) do |csv|
+    csv << [' foo ', 0]
+    csv << [' bar ', 1]
+    csv << [' baz ', 2]
+  end
+  output_string # => "foo,0\nbar,1\nbaz,2\n"
+
+==== Recipe: Specify Multiple Write Converters
+
+Use option <tt>:write_converters</tt> and multiple custom coverters
+to convert field values when generating \CSV.
+
+This example defines and uses two custom write converters to strip and upcase generated fields:
+  strip_converter = proc {|field| field.respond_to?(:strip) ? field.strip : field }
+  upcase_converter = proc {|field| field.respond_to?(:upcase) ? field.upcase : field }
+  converters = [strip_converter, upcase_converter]
+  output_string = CSV.generate(write_converters: converters) do |csv|
+    csv << [' foo ', 0]
+    csv << [' bar ', 1]
+    csv << [' baz ', 2]
+  end
+  output_string # => "FOO,0\nBAR,1\nBAZ,2\n"
+
+=== RFC 4180 Compliance
+
+By default, \CSV generates data that is compliant with
+{RFC 4180}[https://tools.ietf.org/html/rfc4180]
+with respect to:
+- Column separator.
+- Quote character.
+
+==== Row Separator
+
+RFC 4180 specifies the row separator CRLF (Ruby <tt>"\r\n"</tt>).
+
+===== Recipe: Generate Compliant Row Separator
+
+For strict compliance, use option +:row_sep+ to specify row separator <tt>"\r\n"</tt>:
+  output_string = CSV.generate('', row_sep: "\r\n") do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Foo,0\r\nBar,1\r\nBaz,2\r\n"
+
+===== Recipe: Generate Non-Compliant Row Separator
+
+For data with non-compliant row separators, use option +:row_sep+ with a different value:
+This example source uses semicolon (<tt>";'</tt>) as its row separator:
+  output_string = CSV.generate('', row_sep: ";") do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Foo,0;Bar,1;Baz,2;"
+
+==== Column Separator
+
+RFC 4180 specifies column separator COMMA (Ruby <tt>","</tt>).
+
+===== Recipe: Generate Compliant Column Separator
+
+Because the \CSV default comma separator is <tt>","</tt>,
+you need not specify option +:col_sep+ for compliant data:
+  output_string = CSV.generate('') do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Foo,0\nBar,1\nBaz,2\n"
+
+===== Recipe: Generate Non-Compliant Column Separator
+
+For data with non-compliant column separators, use option +:col_sep+.
+This example source uses TAB (<tt>"\t"</tt>) as its column separator:
+  output_string = CSV.generate('', col_sep: "\t") do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "Foo\t0\nBar\t1\nBaz\t2\n"
+
+==== Quote Character
+
+RFC 4180 specifies quote character DQUOTE (Ruby <tt>"\""</tt>).
+
+===== Recipe: Generate Compliant Quote Character
+
+Because the \CSV default quote character is <tt>"\""</tt>,
+you need not specify option +:quote_char+ for compliant data:
+  output_string = CSV.generate('', force_quotes: true) do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "\"Foo\",\"0\"\n\"Bar\",\"1\"\n\"Baz\",\"2\"\n"
+
+===== Recipe: Generate Non-Compliant Quote Character
+
+For data with non-compliant quote characters, use option +:quote_char+.
+This example source uses SQUOTE (<tt>"'"</tt>) as its quote character:
+  output_string = CSV.generate('', quote_char: "'", force_quotes: true) do |csv|
+    csv << ['Foo', 0]
+    csv << ['Bar', 1]
+    csv << ['Baz', 2]
+  end
+  output_string # => "'Foo','0'\n'Bar','1'\n'Baz','2'\n"

+
+=== Source Formats
+
+You can parse \CSV data from a \String, from a \File (via its path), or from an \IO stream.
+
+==== Parsing from a \String
+
+You can parse \CSV data from a \String, with or without headers.
+
+===== Recipe: Parse from \String with Headers
+
+Use class method CSV.parse with option +headers+ to read a source \String all at once
+(may have memory resource implications):
+  string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  CSV.parse(string, headers: true) # => #<CSV::Table mode:col_or_row row_count:4>
+
+Use instance method CSV#each with option +headers+ to read a source \String one row at a time:
+  CSV.new(string, headers: true).each do |row|
+    p row
+  end
+Output:
+  #<CSV::Row "Name":"foo" "Value":"0">
+  #<CSV::Row "Name":"bar" "Value":"1">
+  #<CSV::Row "Name":"baz" "Value":"2">
+
+===== Recipe: Parse from \String Without Headers
+
+Use class method CSV.parse without option +headers+ to read a source \String all at once
+(may have memory resource implications):
+  string = "foo,0\nbar,1\nbaz,2\n"
+  CSV.parse(string) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+
+Use instance method CSV#each without option +headers+ to read a source \String one row at a time:
+  CSV.new(string).each do |row|
+    p row
+  end
+Output:
+  ["foo", "0"]
+  ["bar", "1"]
+  ["baz", "2"]
+
+==== Parsing from a \File
+
+You can parse \CSV data from a \File, with or without headers.
+
+===== Recipe: Parse from \File with Headers
+
+Use instance method CSV#read with option +headers+ to read a file all at once:
+  string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  path = 't.csv'
+  File.write(path, string)
+  CSV.read(path, headers: true) # => #<CSV::Table mode:col_or_row row_count:4>
+
+Use class method CSV.foreach with option +headers+ to read one row at a time:
+  CSV.foreach(path, headers: true) do |row|
+    p row
+  end
+Output:
+  #<CSV::Row "Name":"foo" "Value":"0">
+  #<CSV::Row "Name":"bar" "Value":"1">
+  #<CSV::Row "Name":"baz" "Value":"2">
+
+===== Recipe: Parse from \File Without Headers
+
+Use class method CSV.read without option +headers+ to read a file all at once:
+  string = "foo,0\nbar,1\nbaz,2\n"
+  path = 't.csv'
+  File.write(path, string)
+  CSV.read(path) # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+
+Use class method CSV.foreach without option +headers+ to read one row at a time:
+  CSV.foreach(path) do |row|
+    p row
+  end
+Output:
+  ["foo", "0"]
+  ["bar", "1"]
+  ["baz", "2"]
+
+==== Parsing from an \IO Stream
+
+You can parse \CSV data from an \IO stream, with or without headers.
+
+===== Recipe: Parse from \IO Stream with Headers
+
+Use class method CSV.parse with option +headers+ to read an \IO stream all at once:
+  string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  path = 't.csv'
+  File.write(path, string)
+  File.open(path) do |file|
+    CSV.parse(file, headers: true)
+  end # => #<CSV::Table mode:col_or_row row_count:4>
+
+Use class method CSV.foreach with option +headers+ to read one row at a time:
+  File.open(path) do |file|
+    CSV.foreach(file, headers: true) do |row|
+      p row
+    end
+  end
+Output:
+  #<CSV::Row "Name":"foo" "Value":"0">
+  #<CSV::Row "Name":"bar" "Value":"1">
+  #<CSV::Row "Name":"baz" "Value":"2">
+
+===== Recipe: Parse from \IO Stream Without Headers
+
+Use class method CSV.parse without option +headers+ to read an \IO stream all at once:
+  string = "foo,0\nbar,1\nbaz,2\n"
+  path = 't.csv'
+  File.write(path, string)
+  File.open(path) do |file|
+    CSV.parse(file)
+  end # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+
+Use class method CSV.foreach without option +headers+ to read one row at a time:
+  File.open(path) do |file|
+    CSV.foreach(file) do |row|
+      p row
+    end
+  end
+Output:
+  ["foo", "0"]
+  ["bar", "1"]
+  ["baz", "2"]
+
+=== RFC 4180 Compliance
+
+By default, \CSV parses data that is compliant with
+{RFC 4180}[https://tools.ietf.org/html/rfc4180]
+with respect to:
+- Row separator.
+- Column separator.
+- Quote character.
+
+==== Row Separator
+
+RFC 4180 specifies the row separator CRLF (Ruby <tt>"\r\n"</tt>).
+
+Although the \CSV default row separator is <tt>"\n"</tt>,
+the parser also by default handles row separator <tt>"\r"</tt> and the RFC-compliant <tt>"\r\n"</tt>.
+
+===== Recipe: Handle Compliant Row Separator
+
+For strict compliance, use option +:row_sep+ to specify row separator <tt>"\r\n"</tt>,
+which allows the compliant row separator:
+  source = "foo,1\r\nbar,1\r\nbaz,2\r\n"
+  CSV.parse(source, row_sep: "\r\n") # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+But rejects other row separators:
+  source = "foo,1\nbar,1\nbaz,2\n"
+  CSV.parse(source, row_sep: "\r\n") # Raised MalformedCSVError
+  source = "foo,1\rbar,1\rbaz,2\r"
+  CSV.parse(source, row_sep: "\r\n") # Raised MalformedCSVError
+  source = "foo,1\n\rbar,1\n\rbaz,2\n\r"
+  CSV.parse(source, row_sep: "\r\n") # Raised MalformedCSVError
+
+===== Recipe: Handle Non-Compliant Row Separator
+
+For data with non-compliant row separators, use option +:row_sep+.
+This example source uses semicolon (<tt>";"</tt>) as its row separator:
+  source = "foo,1;bar,1;baz,2;"
+  CSV.parse(source, row_sep: ';') # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+
+==== Column Separator
+
+RFC 4180 specifies column separator COMMA (Ruby <tt>","</tt>).
+
+===== Recipe: Handle Compliant Column Separator
+
+Because the \CSV default comma separator is ',',
+you need not specify option +:col_sep+ for compliant data:
+  source = "foo,1\nbar,1\nbaz,2\n"
+  CSV.parse(source) # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+
+===== Recipe: Handle Non-Compliant Column Separator
+
+For data with non-compliant column separators, use option +:col_sep+.
+This example source uses TAB (<tt>"\t"</tt>) as its column separator:
+  source = "foo,1\tbar,1\tbaz,2"
+  CSV.parse(source, col_sep: "\t") # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+
+==== Quote Character
+
+RFC 4180 specifies quote character DQUOTE (Ruby <tt>"\""</tt>).
+
+===== Recipe: Handle Compliant Quote Character
+
+Because the \CSV default quote character is <tt>"\""</tt>,
+you need not specify option +:quote_char+ for compliant data:
+  source = "\"foo\",\"1\"\n\"bar\",\"1\"\n\"baz\",\"2\"\n"
+  CSV.parse(source) # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+
+===== Recipe: Handle Non-Compliant Quote Character
+
+For data with non-compliant quote characters, use option +:quote_char+.
+This example source uses SQUOTE (<tt>"'"</tt>) as its quote character:
+  source = "'foo','1'\n'bar','1'\n'baz','2'\n"
+  CSV.parse(source, quote_char: "'") # => [["foo", "1"], ["bar", "1"], ["baz", "2"]]
+
+==== Recipe: Allow Liberal Parsing
+
+Use option +:liberal_parsing+ to specify that \CSV should
+attempt to parse input not conformant with RFC 4180, such as double quotes in unquoted fields:
+  source = 'is,this "three, or four",fields'
+  CSV.parse(source) # Raises MalformedCSVError
+  CSV.parse(source, liberal_parsing: true) # => [["is", "this \"three", " or four\"", "fields"]]
+
+=== Special Handling
+
+You can use parsing options to specify special handling for certain lines and fields.
+
+==== Special Line Handling
+
+Use parsing options to specify special handling for blank lines, or for other selected lines.
+
+===== Recipe: Ignore Blank Lines
+
+Use option +:skip_blanks+ to ignore blank lines:
+  source = <<-EOT
+  foo,0
+
+  bar,1
+  baz,2
+
+  ,
+  EOT
+  parsed = CSV.parse(source, skip_blanks: true)
+  parsed # => [["foo", "0"], ["bar", "1"], ["baz", "2"], [nil, nil]]
+
+===== Recipe: Ignore Selected Lines
+
+Use option +:skip_lines+ to ignore selected lines.
+  source = <<-EOT
+  # Comment
+  foo,0
+  bar,1
+  baz,2
+  # Another comment
+  EOT
+  parsed = CSV.parse(source, skip_lines: /^#/)
+  parsed # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+
+==== Special Field Handling
+
+Use parsing options to specify special handling for certain field values.
+
+===== Recipe: Strip Fields
+
+Use option +:strip+ to strip parsed field values:
+  CSV.parse_line(' a , b ', strip: true) # => ["a", "b"]
+
+===== Recipe: Handle Null Fields
+
+Use option +:nil_value+ to specify a value that will replace each field
+that is null (no text):
+  CSV.parse_line('a,,b,,c', nil_value: 0) # => ["a", 0, "b", 0, "c"]
+
+===== Recipe: Handle Empty Fields
+
+Use option +:empty_value+ to specify a value that will replace each field
+that is empty (\String of length 0);
+  CSV.parse_line('a,"",b,"",c', empty_value: 'x') # => ["a", "x", "b", "x", "c"]
+
+=== Converting Fields
+
+You can use field converters to change parsed \String fields into other objects,
+or to otherwise modify the \String fields.
+
+==== Converting Fields to Objects
+
+Use field converters to change parsed \String objects into other, more specific, objects.
+
+There are built-in field converters for converting to objects of certain classes:
+- \Float
+- \Integer
+- \Date
+- \DateTime
+
+Other built-in field converters include:
+- +:numeric+: converts to \Integer and \Float.
+- +:all+: converts to \DateTime, \Integer, \Float.
+
+You can also define field converters to convert to objects of other classes.
+
+===== Recipe: Convert Fields to Integers
+
+Convert fields to \Integer objects using built-in converter +:integer+:
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, converters: :integer)
+  parsed.map {|row| row['Value'].class} # => [Integer, Integer, Integer]
+
+===== Recipe: Convert Fields to Floats
+
+Convert fields to \Float objects using built-in converter +:float+:
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, converters: :float)
+  parsed.map {|row| row['Value'].class} # => [Float, Float, Float]
+
+===== Recipe: Convert Fields to Numerics
+
+Convert fields to \Integer and \Float objects using built-in converter +:numeric+:
+  source = "Name,Value\nfoo,0\nbar,1.1\nbaz,2.2\n"
+  parsed = CSV.parse(source, headers: true, converters: :numeric)
+  parsed.map {|row| row['Value'].class} # => [Integer, Float, Float]
+
+===== Recipe: Convert Fields to Dates
+
+Convert fields to \Date objects using built-in converter +:date+:
+  source = "Name,Date\nfoo,2001-02-03\nbar,2001-02-04\nbaz,2001-02-03\n"
+  parsed = CSV.parse(source, headers: true, converters: :date)
+  parsed.map {|row| row['Date'].class} # => [Date, Date, Date]
+
+===== Recipe: Convert Fields to DateTimes
+
+Convert fields to \DateTime objects using built-in converter +:date_time+:
+  source = "Name,DateTime\nfoo,2001-02-03\nbar,2001-02-04\nbaz,2020-05-07T14:59:00-05:00\n"
+  parsed = CSV.parse(source, headers: true, converters: :date_time)
+  parsed.map {|row| row['DateTime'].class} # => [DateTime, DateTime, DateTime]
+
+===== Recipe: Convert Assorted Fields to Objects
+
+Convert assorted fields to objects using built-in converter +:all+:
+  source = "Type,Value\nInteger,0\nFloat,1.0\nDateTime,2001-02-04\n"
+  parsed = CSV.parse(source, headers: true, converters: :all)
+  parsed.map {|row| row['Value'].class} # => [Integer, Float, DateTime]
+
+===== Recipe: Convert Fields to Other Objects
+
+Define a custom field converter to convert \String fields into other objects.
+This example defines and uses a custom field converter
+that converts each column-1 value to a \Rational object:
+  rational_converter = proc do |field, field_context|
+    field_context.index == 1 ? field.to_r : field
+  end
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, converters: rational_converter)
+  parsed.map {|row| row['Value'].class} # => [Rational, Rational, Rational]
+
+==== Recipe: Filter Field Strings
+
+Define a custom field converter to modify \String fields.
+This example defines and uses a custom field converter
+that strips whitespace from each field value:
+  strip_converter = proc {|field| field.strip }
+  source = "Name,Value\n foo , 0 \n bar , 1 \n baz , 2 \n"
+  parsed = CSV.parse(source, headers: true, converters: strip_converter)
+  parsed['Name'] # => ["foo", "bar", "baz"]
+  parsed['Value'] # => ["0", "1", "2"]
+
+==== Recipe: Register Field Converters
+
+Register a custom field converter, assigning it a name;
+then refer to the converter by its name:
+  rational_converter = proc do |field, field_context|
+    field_context.index == 1 ? field.to_r : field
+  end
+  CSV::Converters[:rational] = rational_converter
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, converters: :rational)
+  parsed['Value'] # => [(0/1), (1/1), (2/1)]
+
+==== Using Multiple Field Converters
+
+You can use multiple field converters in either of these ways:
+- Specify converters in option +:converters+.
+- Specify converters in a custom converter list.
+
+===== Recipe: Specify Multiple Field Converters in Option +:converters+
+
+Apply multiple field converters by specifying them in option +:converters+:
+  source = "Name,Value\nfoo,0\nbar,1.0\nbaz,2.0\n"
+  parsed = CSV.parse(source, headers: true, converters: [:integer, :float])
+  parsed['Value'] # => [0, 1.0, 2.0]
+
+===== Recipe: Specify Multiple Field Converters in a Custom Converter List
+
+Apply multiple field converters by defining and registering a custom converter list:
+  strip_converter = proc {|field| field.strip }
+  CSV::Converters[:strip] = strip_converter
+  CSV::Converters[:my_converters] = [:integer, :float, :strip]
+  source = "Name,Value\n foo , 0 \n bar , 1.0 \n baz , 2.0 \n"
+  parsed = CSV.parse(source, headers: true, converters: :my_converters)
+  parsed['Name'] # => ["foo", "bar", "baz"]
+  parsed['Value'] # => [0, 1.0, 2.0]
+
+=== Converting Headers
+
+You can use header converters to modify parsed \String headers.
+
+Built-in header converters include:
+- +:symbol+: converts \String header to \Symbol.
+- +:downcase+: converts \String header to lowercase.
+
+You can also define header converters to otherwise modify header \Strings.
+
+==== Recipe: Convert Headers to Lowercase
+
+Convert headers to lowercase using built-in converter +:downcase+:
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, header_converters: :downcase)
+  parsed.headers # => ["name", "value"]
+
+==== Recipe: Convert Headers to Symbols
+
+Convert headers to downcased Symbols using built-in converter +:symbol+:
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, header_converters: :symbol)
+  parsed.headers # => [:name, :value]
+  parsed.headers.map {|header| header.class} # => [Symbol, Symbol]
+
+==== Recipe: Filter Header Strings
+
+Define a custom header converter to modify \String fields.
+This example defines and uses a custom header converter
+that capitalizes each header \String:
+  capitalize_converter = proc {|header| header.capitalize }
+  source = "NAME,VALUE\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, header_converters: capitalize_converter)
+  parsed.headers # => ["Name", "Value"]
+
+==== Recipe: Register Header Converters
+
+Register a custom header converter, assigning it a name;
+then refer to the converter by its name:
+  capitalize_converter = proc {|header| header.capitalize }
+  CSV::HeaderConverters[:capitalize] = capitalize_converter
+  source = "NAME,VALUE\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, headers: true, header_converters: :capitalize)
+  parsed.headers # => ["Name", "Value"]
+
+==== Using Multiple Header Converters
+
+You can use multiple header converters in either of these ways:
+- Specify header converters in option +:header_converters+.
+- Specify header converters in a custom header converter list.
+
+===== Recipe: Specify Multiple Header Converters in Option :header_converters
+
+Apply multiple header converters by specifying them in option +:header_converters+:
+  source = "Name,Value\nfoo,0\nbar,1.0\nbaz,2.0\n"
+  parsed = CSV.parse(source, headers: true, header_converters: [:downcase, :symbol])
+  parsed.headers # => [:name, :value]
+
+===== Recipe: Specify Multiple Header Converters in a Custom Header Converter List
+
+Apply multiple header converters by defining and registering a custom header converter list:
+  CSV::HeaderConverters[:my_header_converters] = [:symbol, :downcase]
+  source = "NAME,VALUE\nfoo,0\nbar,1.0\nbaz,2.0\n"
+  parsed = CSV.parse(source, headers: true, header_converters: :my_header_converters)
+  parsed.headers # => [:name, :value]
+
+=== Diagnostics
+
+==== Recipe: Capture Unconverted Fields
+
+To capture unconverted field values, use option +:unconverted_fields+:
+  source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
+  parsed = CSV.parse(source, converters: :integer, unconverted_fields: true)
+  parsed # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+  parsed.each {|row| p row.unconverted_fields }
+Output:
+  ["Name", "Value"]
+  ["foo", "0"]
+  ["bar", "1"]
+  ["baz", "2"]
+
+==== Recipe: Capture Field Info
+
+To capture field info in a custom converter, accept two block arguments.
+The first is the field value; the second is a +CSV::FieldInfo+ object:
+  strip_converter = proc {|field, field_info| p field_info; field.strip }
+  source = " foo , 0 \n bar , 1 \n baz , 2 \n"
+  parsed = CSV.parse(source, converters: strip_converter)
+  parsed # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]
+Output:
+  #<struct CSV::FieldInfo index=0, line=1, header=nil>
+  #<struct CSV::FieldInfo index=1, line=1, header=nil>
+  #<struct CSV::FieldInfo index=0, line=2, header=nil>
+  #<struct CSV::FieldInfo index=1, line=2, header=nil>
+  #<struct CSV::FieldInfo index=0, line=3, header=nil>
+  #<struct CSV::FieldInfo index=1, line=3, header=nil>

+== Julian and Gregorian Calendars
+
+The difference between the
+{Julian calendar}[https://en.wikipedia.org/wiki/Julian_calendar]
+and the
+{Gregorian calendar}[https://en.wikipedia.org/wiki/Gregorian_calendar]
+may matter to your program if it uses dates before the switchovers.
+
+- October 15, 1582.
+- September 14, 1752.
+
+A date will be different in the two calendars, in general.
+
+=== Different switchover dates
+
+The reasons for the difference are religious/political histories.
+
+- On October 15, 1582, several countries changed
+  from the Julian calendar to the Gregorian calendar;
+  these included Italy, Poland, Portugal, and Spain.
+  Other contries in the Western world retained the Julian calendar.
+- On September 14, 1752, most of the British empire
+  changed from the Julian calendar to the Gregorian calendar.
+
+When your code uses a date before these switchover dates,
+it will matter whether it considers the switchover date
+to be the earlier date or the later date (or neither).
+
+See also {a concrete example here}[rdoc-ref:DateTime@When+should+you+use+DateTime+and+when+should+you+use+Time-3F].
+
+=== Argument +start+
+
+Certain methods in class \Date handle differences in the
+{Julian and Gregorian calendars}[rdoc-ref:calendars.rdoc@Julian+and+Gregorian+Calendars]
+by accepting an optional argument +start+, whose value may be:
+
+- Date::ITALY (the default): the created date is Julian
+  if before October 15, 1582, Gregorian otherwise:
+
+      d = Date.new(1582, 10, 15)
+      d.prev_day.julian? # => true
+      d.julian?          # => false
+      d.gregorian?       # => true
+
+- Date::ENGLAND: the created date is Julian if before September 14, 1752,
+  Gregorian otherwise:
+
+    d = Date.new(1752, 9, 14, Date::ENGLAND)
+    d.prev_day.julian? # => true
+    d.julian?          # => false
+    d.gregorian?       # => true
+
+- Date::JULIAN: the created date is Julian regardless of its value:
+
+    d = Date.new(1582, 10, 15, Date::JULIAN)
+    d.julian? # => true
+
+- Date::GREGORIAN: the created date is Gregorian regardless of its value:
+
+    d = Date.new(1752, 9, 14, Date::GREGORIAN)
+    d.prev_day.gregorian? # => true

+= Dig Methods
+
+Ruby's +dig+ methods are useful for accessing nested data structures.
+
+Consider this data:
+    item = {
+      id: "0001",
+      type: "donut",
+      name: "Cake",
+      ppu: 0.55,
+      batters: {
+        batter: [
+          {id: "1001", type: "Regular"},
+          {id: "1002", type: "Chocolate"},
+          {id: "1003", type: "Blueberry"},
+          {id: "1004", type: "Devil's Food"}
+        ]
+      },
+      topping: [
+        {id: "5001", type: "None"},
+        {id: "5002", type: "Glazed"},
+        {id: "5005", type: "Sugar"},
+        {id: "5007", type: "Powdered Sugar"},
+        {id: "5006", type: "Chocolate with Sprinkles"},
+        {id: "5003", type: "Chocolate"},
+        {id: "5004", type: "Maple"}
+      ]
+    }
+
+Without a +dig+ method, you can write:
+    item[:batters][:batter][1][:type] # => "Chocolate"
+
+With a +dig+ method, you can write:
+    item.dig(:batters, :batter, 1, :type) # => "Chocolate"
+
+Without a +dig+ method, you can write, erroneously
+(raises <tt>NoMethodError (undefined method `[]' for nil:NilClass)</tt>):
+    item[:batters][:BATTER][1][:type]
+
+With a +dig+ method, you can write (still erroneously, but avoiding the exception):
+    item.dig(:batters, :BATTER, 1, :type) # => nil
+
+== Why Is +dig+ Better?
+
+- It has fewer syntactical elements (to get wrong).
+- It reads better.
+- It does not raise an exception if an item is not found.
+
+== How Does +dig+ Work?
+
+The call sequence is:
+  obj.dig(*identifiers)
+
+The +identifiers+ define a "path" into the nested data structures:
+- For each identifier in +identifiers+, calls method \#dig on a receiver
+  with that identifier.
+- The first receiver is +self+.
+- Each successive receiver is the value returned by the previous call to +dig+.
+- The value finally returned is the value returned by the last call to +dig+.
+
+A +dig+ method raises an exception if any receiver does not respond to \#dig:
+  h = { foo: 1 }
+  # Raises TypeError (Integer does not have #dig method):
+  h.dig(:foo, :bar)
+
+== What Else?
+
+The structure above has \Hash objects and \Array objects,
+both of which have instance method +dig+.
+
+Altogether there are six built-in Ruby classes that have method +dig+,
+three in the core classes and three in the standard library.
+
+In the core:
+- Array#dig: the first argument is an \Integer index.
+- Hash#dig: the first argument is a key.
+- Struct#dig: the first argument is a key.
+
+In the standard library:
+- OpenStruct#dig: the first argument is a \String name.
+- CSV::Table#dig: the first argument is an \Integer index or a \String header.
+- CSV::Row#dig: the first argument is an \Integer index or a \String header.

+= DTrace Probes
+
+A list of DTrace probes and their functionality. "Module" and "Function" cannot
+be defined in user defined probes (known as USDT), so they will not be
+specified. Probe definitions are in the format of:
+
+  provider:module:function:name(arguments)
+
+Since module and function cannot be specified, they will be blank. An example
+probe definition for Ruby would then be:
+
+  ruby:::method-entry(class name, method name, file name, line number)
+
+Where "ruby" is the provider name, module and function names are blank, the
+probe name is "method-entry", and the probe takes four arguments:
+
+* class name
+* method name
+* file name
+* line number
+
+== Probes List
+
+=== Stability
+
+Before we list the specific probes, let's talk about stability. Probe stability
+is declared in the probes.d file at the bottom on the #pragma D attributes
+lines. Here is a description of each of the stability declarations.
+
+[Provider name stability]
+  The provider name of "ruby" has been declared as stable. It is unlikely that
+  we will change the provider name from "ruby" to something else.
+
+[Module and Function stability]
+  Since we are not allowed to provide values for the module and function name,
+  the values we have provided (no value) is declared as stable.
+
+[Probe name stability]
+  The probe names are likely to change in the future, so they are marked as
+  "Evolving". Consumers should not depend on these names to be stable.
+
+[Probe argument stability]
+  The parameters passed to the probes are likely to change in the future, so
+  they are marked as "Evolving". Consumers should not depend on these to be
+  stable.
+
+=== Declared probes
+
+Probes are defined in the probes.d file. Here are the declared probes along
+with when they are fired and the arguments they take:
+
+[ruby:::method-entry(classname, methodname, filename, lineno);]
+  This probe is fired just before a method is entered.
+
+  classname::    name of the class (a string)
+  methodname::   name of the method about to be executed (a string)
+  filename::     the file name where the method is _being called_ (a string)
+  lineno::       the line number where the method is _being called_ (an int)
+
+  *NOTE*: will only be fired if tracing is enabled, e.g. with: <code>TracePoint.new{}.enable</code>.
+  See Feature#14104[https://bugs.ruby-lang.org/issues/14104] for more details.
+
+[ruby:::method-return(classname, methodname, filename, lineno);]
+  This probe is fired just after a method has returned. The arguments are the
+  same as "ruby:::method-entry".
+
+  *NOTE*: will only be fired if tracing is enabled, e.g. with: <code>TracePoint.new{}.enable</code>.
+  See Feature#14104[https://bugs.ruby-lang.org/issues/14104] for more details.
+
+[ruby:::cmethod-entry(classname, methodname, filename, lineno);]
+  This probe is fired just before a C method is entered. The arguments are the
+  same as "ruby:::method-entry".
+
+[ruby:::cmethod-return(classname, methodname, filename, lineno);]
+  This probe is fired just before a C method returns. The arguments are the
+  same as "ruby:::method-entry".
+
+[ruby:::require-entry(requiredfile, filename, lineno);]
+  This probe is fired on calls to rb_require_safe (when a file is required).
+
+  requiredfile:: the name of the file to be required (string).
+  filename::     the file that called "+require+" (string).
+  lineno::       the line number where the call to require was made (int).
+
+[ruby:::require-return(requiredfile, filename, lineno);]
+  This probe is fired just before rb_require_safe (when a file is required)
+  returns. The arguments are the same as "ruby:::require-entry". This probe
+  will not fire if there was an exception during file require.
+
+[ruby:::find-require-entry(requiredfile, filename, lineno);]
+  This probe is fired right before search_required is called. search_required
+  determines whether the file has already been required by searching loaded
+  features (<code>$"</code>), and if not, figures out which file must be loaded.
+
+  requiredfile:: the file to be required (string).
+  filename::     the file that called "require" (string).
+  lineno::       the line number where the call to require was made (int).
+
+[ruby:::find-require-return(requiredfile, filename, lineno);]
+  This probe is fired right after search_required returns. See the
+  documentation for "ruby:::find-require-entry" for more details. Arguments for
+  this probe are the same as "ruby:::find-require-entry".
+
+[ruby:::load-entry(loadedfile, filename, lineno);]
+  This probe is fired when calls to "load" are made. The arguments are the same
+  as "ruby:::require-entry".
+
+[ruby:::load-return(loadedfile, filename, lineno);]
+  This probe is fired when "load" returns. The arguments are the same as
+  "ruby:::load-entry".
+
+[ruby:::raise(classname, filename, lineno);]
+  This probe is fired when an exception is raised.
+
+  classname::    the class name of the raised exception (string)
+  filename::     the name of the file where the exception was raised (string)
+  lineno::       the line number in the file where the exception was raised (int)
+
+[ruby:::object-create(classname, filename, lineno);]
+  This probe is fired when an object is about to be allocated.
+
+  classname::    the class of the allocated object (string)
+  filename::     the name of the file where the object is allocated (string)
+  lineno::       the line number in the file where the object is allocated (int)
+
+[ruby:::array-create(length, filename, lineno);]
+  This probe is fired when an Array is about to be allocated.
+
+  length::       the size of the array (long)
+  filename::     the name of the file where the array is allocated (string)
+  lineno::       the line number in the file where the array is allocated (int)

+  lineno::       the line number in the file where the string is allocated (int)
+
+[ruby:::symbol-create(str, filename, lineno);]
+  This probe is fired when a Symbol is about to be allocated.
+
+  str::          the contents of the symbol (string)
+  filename::     the name of the file where the string is allocated (string)
+  lineno::       the line number in the file where the string is allocated (int)

+== Encodings
+
+=== The Basics
+
+A {character encoding}[https://en.wikipedia.org/wiki/Character_encoding],
+often shortened to _encoding_, is a mapping between:
+
+- A sequence of 8-bit bytes (each byte in the range <tt>0..255</tt>).
+- Characters in a specific character set.
+
+Some character sets contain only 1-byte characters;
+{US-ASCII}[https://en.wikipedia.org/wiki/ASCII], for example, has 256 1-byte characters.
+This string, encoded in US-ASCII, has six characters that are stored as six bytes:
+
+  s = 'Hello!'.encode('US-ASCII')  # => "Hello!"
+  s.encoding                       # => #<Encoding:US-ASCII>
+  s.bytes                          # => [72, 101, 108, 108, 111, 33]
+
+Other encodings may involve multi-byte characters.
+{UTF-8}[https://en.wikipedia.org/wiki/UTF-8], for example,
+encodes more than one million characters, encoding each in one to four bytes.
+The lowest-valued of these characters correspond to ASCII characters,
+and so are 1-byte characters:
+
+  s = 'Hello!' # => "Hello!"
+  s.bytes      # => [72, 101, 108, 108, 111, 33]
+
+Other characters, such as the Euro symbol, are multi-byte:
+
+  s = "\u20ac" # => "€"
+  s.bytes      # => [226, 130, 172]
+
+=== The \Encoding \Class
+
+==== \Encoding Objects
+
+Ruby encodings are defined by constants in class \Encoding.
+There can be only one instance of \Encoding for each of these constants.
+\Method Encoding.list returns an array of \Encoding objects (one for each constant):
+
+  Encoding.list.size        # => 103
+  Encoding.list.first.class # => Encoding
+  Encoding.list.take(3)
+  # => [#<Encoding:ASCII-8BIT>, #<Encoding:UTF-8>, #<Encoding:US-ASCII>]
+
+==== Names and Aliases
+
+\Method Encoding#name returns the name of an \Encoding:
+
+  Encoding::ASCII_8BIT.name  # => "ASCII-8BIT"
+  Encoding::WINDOWS_31J.name # => "Windows-31J"
+
+An \Encoding object has zero or more aliases;
+method Encoding#names returns an array containing the name and all aliases:
+
+  Encoding::ASCII_8BIT.names
+  # => ["ASCII-8BIT", "BINARY"]
+  Encoding::WINDOWS_31J.names
+  #=> ["Windows-31J", "CP932", "csWindows31J", "SJIS", "PCK"]
+
+\Method Encoding.aliases returns a hash of all alias/name pairs:
+
+  Encoding.aliases.size # => 71
+  Encoding.aliases.take(3)
+  # => [["BINARY", "ASCII-8BIT"], ["CP437", "IBM437"], ["CP720", "IBM720"]]
+
+\Method Encoding.name_list returns an array of all the encoding names and aliases:
+
+  Encoding.name_list.size # => 175
+  Encoding.name_list.take(3)
+  # => ["ASCII-8BIT", "UTF-8", "US-ASCII"]
+
+\Method +name_list+ returns more entries than method +list+
+because it includes both the names and their aliases.
+
+\Method Encoding.find returns the \Encoding for a given name or alias, if it exists:
+
+  Encoding.find("US-ASCII")       # => #<Encoding:US-ASCII>
+  Encoding.find("US-ASCII").class # => Encoding
+
+==== Default Encodings
+
+\Method Encoding.find, above, also returns a default \Encoding
+for each of these special names:
+
+- +external+: the default external \Encoding:
+
+    Encoding.find("external") # => #<Encoding:UTF-8>
+
+- +internal+: the default internal \Encoding (may be +nil+):
+
+    Encoding.find("internal") # => nil
+
+- +locale+: the default \Encoding for a string from the environment:
+
+    Encoding.find("locale") # => #<Encoding:UTF-8>  # Linux
+    Encoding.find("locale") # => #<Encoding:IBM437> # Windows
+
+- +filesystem+: the default \Encoding for a string from the filesystem:
+
+    Encoding.find("filesystem") # => #<Encoding:UTF-8>
+
+\Method Encoding.default_external returns the default external \Encoding:
+
+  Encoding.default_external # => #<Encoding:UTF-8>
+
+\Method Encoding.default_external= sets that value:
+
+  Encoding.default_external = 'US-ASCII' # => "US-ASCII"
+  Encoding.default_external              # => #<Encoding:US-ASCII>
+
+\Method Encoding.default_internal returns the default internal \Encoding:
+
+  Encoding.default_internal # => nil
+
+\Method Encoding.default_internal= sets the default internal \Encoding:
+
+  Encoding.default_internal = 'US-ASCII' # => "US-ASCII"
+  Encoding.default_internal              # => #<Encoding:US-ASCII>
+
+==== Compatible Encodings
+
+\Method Encoding.compatible? returns whether two given objects are encoding-compatible
+(that is, whether they can be concatenated);
+returns the \Encoding of the concatenated string, or +nil+ if incompatible:
+
+  rus = "\u{442 435 441 442}"
+  eng = 'text'
+  Encoding.compatible?(rus, eng) # => #<Encoding:UTF-8>
+
+  s0 = "\xa1\xa1".force_encoding('iso-8859-1') # => "\xA1\xA1"
+  s1 = "\xa1\xa1".force_encoding('euc-jp')     # => "\x{A1A1}"
+  Encoding.compatible?(s0, s1)                 # => nil
+
+=== \String \Encoding
+
+A Ruby String object has an encoding that is an instance of class \Encoding.
+The encoding may be retrieved by method String#encoding.
+
+The default encoding for a string literal is the script encoding
+(see Encoding@Script+encoding):
+
+  's'.encoding # => #<Encoding:UTF-8>
+
+The default encoding for a string created with method String.new is:
+
+- For a \String object argument, the encoding of that string.
+- For a string literal, the script encoding (see Encoding@Script+encoding).
+
+In either case, any encoding may be specified:
+
+  s = String.new(encoding: 'UTF-8')             # => ""
+  s.encoding                                    # => #<Encoding:UTF-8>
+  s = String.new('foo', encoding: 'ASCII-8BIT') # => "foo"
+  s.encoding                                    # => #<Encoding:ASCII-8BIT>
+
+The encoding for a string may be changed:
+
+  s = "R\xC3\xA9sum\xC3\xA9"     # => "Résumé"
+  s.encoding                     # => #<Encoding:UTF-8>
+  s.force_encoding('ISO-8859-1') # => "R\xC3\xA9sum\xC3\xA9"
+  s.encoding                     # => #<Encoding:ISO-8859-1>
+
+Changing the assigned encoding does not alter the content of the string;
+it changes only the way the content is to be interpreted:
+
+  s                         # => "R\xC3\xA9sum\xC3\xA9"
+  s.force_encoding('UTF-8') # => "Résumé"
+
+The actual content of a string may also be altered;
+see {Transcoding a String}[#label-Transcoding+a+String].
+
+Here are a couple of useful query methods:
+
+  s = "abc".force_encoding("UTF-8")         # => "abc"
+  s.ascii_only?                             # => true
+  s = "abc\u{6666}".force_encoding("UTF-8") # => "abc晦"
+  s.ascii_only?                             # => false
+
+  s = "\xc2\xa1".force_encoding("UTF-8") # => "¡"
+  s.valid_encoding?                      # => true
+  s = "\xc2".force_encoding("UTF-8")     # => "\xC2"
+  s.valid_encoding?                      # => false
+
+=== \Symbol and \Regexp Encodings
+
+The string stored in a Symbol or Regexp object also has an encoding;
+the encoding may be retrieved by method Symbol#encoding or Regexp#encoding.
+
+The default encoding for these, however, is:
+
+- US-ASCII, if all characters are US-ASCII.
+- The script encoding, otherwise (see Encoding@Script+encoding).
+
+=== Filesystem \Encoding
+
+The filesystem encoding is the default \Encoding for a string from the filesystem:
+
+    Encoding.find("filesystem") # => #<Encoding:UTF-8>
+
+=== Locale \Encoding
+
+The locale encoding is the default encoding for a string from the environment,
+other than from the filesystem:
+
+  Encoding.find('locale') # => #<Encoding:IBM437>
+
+=== Stream Encodings
+
+Certain stream objects can have two encodings; these objects include instances of:
+
+- IO.
+- File.
+- ARGF.
+- StringIO.
+
+The two encodings are:
+
+- An _external_ _encoding_, which identifies the encoding of the stream.
+- An _internal_ _encoding_, which (if not +nil+) specifies the encoding
+  to be used for the string constructed from the stream.
+
+==== External \Encoding
+
+The external encoding, which is an \Encoding object, specifies how bytes read
+from the stream are to be interpreted as characters.
+
+The default external encoding is:
+
+- UTF-8 for a text stream.
+- ASCII-8BIT for a binary stream.
+
+The default external encoding is returned by method Encoding.default_external,
+and may be set by:
+
+- Ruby command-line options <tt>--external_encoding</tt> or <tt>-E</tt>.
+
+You can also set the default external encoding using method Encoding.default_external=,
+but doing so may cause problems; strings created before and after the change
+may have a different encodings.
+
+For an \IO or \File object, the external encoding may be set by:
+
+- Open options +external_encoding+ or +encoding+, when the object is created;
+  see {Open Options}[rdoc-ref:IO@Open+Options].
+
+For an \IO, \File, \ARGF, or \StringIO object, the external encoding may be set by:
+
+- \Methods +set_encoding+ or (except for \ARGF) +set_encoding_by_bom+.
+
+==== Internal \Encoding
+
+The internal encoding, which is an \Encoding object or +nil+,
+specifies how characters read from the stream
+are to be converted to characters in the internal encoding;
+those characters become a string whose encoding is set to the internal encoding.
+
+The default internal encoding is +nil+ (no conversion).
+It is returned by method Encoding.default_internal,
+and may be set by:
+
+- Ruby command-line options <tt>--internal_encoding</tt> or <tt>-E</tt>.
+
+You can also set the default internal encoding using method Encoding.default_internal=,
+but doing so may cause problems; strings created before and after the change
+may have a different encodings.
+
+For an \IO or \File object, the internal encoding may be set by:
+
+- Open options +internal_encoding+ or +encoding+, when the object is created;
+  see {Open Options}[rdoc-ref:IO@Open+Options].
+
+For an \IO, \File, \ARGF, or \StringIO object, the internal encoding may be set by:
+
+- \Method +set_encoding+.
+
+=== Script \Encoding
+
+A Ruby script has a script encoding, which may be retrieved by:
+
+  __ENCODING__ # => #<Encoding:UTF-8>
+
+The default script encoding is UTF-8;
+a Ruby source file may set its script encoding with a magic comment
+on the first line of the file (or second line, if there is a shebang on the first).
+The comment must contain the word +coding+ or +encoding+,
+followed by a colon, space and the Encoding name or alias:
+
+  # encoding: ISO-8859-1
+  __ENCODING__ #=> #<Encoding:ISO-8859-1>
+
+=== Transcoding
+
+_Transcoding_ is the process of changing a sequence of characters
+from one encoding to another.
+
+As far as possible, the characters remain the same,
+but the bytes that represent them may change.
+
+The handling for characters that cannot be represented in the destination encoding
+may be specified by @Encoding+Options.
+
+==== Transcoding a \String
+
+Each of these methods transcodes a string:
+
+- String#encode: Transcodes +self+ into a new string
+  according to given encodings and options.
+- String#encode!: Like String#encode, but transcodes +self+ in place.
+- String#scrub: Transcodes +self+ into a new string
+  by replacing invalid byte sequences with a given or default replacement string.
+- String#scrub!: Like String#scrub, but transcodes +self+ in place.
+- String#unicode_normalize: Transcodes +self+ into a new string
+  according to Unicode normalization.
+- String#unicode_normalize!: Like String#unicode_normalize,
+  but transcodes +self+ in place.
+
+=== Transcoding a Stream
+
+Each of these methods may transcode a stream;
+whether it does so depends on the external and internal encodings:
+
+- IO.foreach: Yields each line of given stream to the block.
+- IO.new: Creates and returns a new \IO object for the given integer file descriptor.
+- IO.open: Creates a new \IO object.
+- IO.pipe: Creates a connected pair of reader and writer \IO objects.
+- IO.popen: Creates an \IO object to interact with a subprocess.
+- IO.read: Returns a string with all or a subset of bytes from the given stream.
+- IO.readlines: Returns an array of strings, which are the lines from the given stream.
+- IO.write: Writes a given string to the given stream.
+
+This example writes a string to a file, encoding it as ISO-8859-1,
+then reads the file into a new string, encoding it as UTF-8:
+
+  s = "R\u00E9sum\u00E9"
+  path = 't.tmp'
+  ext_enc = 'ISO-8859-1'
+  int_enc = 'UTF-8'
+
+  File.write(path, s, external_encoding: ext_enc)
+  raw_text = File.binread(path)
+
+  transcoded_text = File.read(path, external_encoding: ext_enc, internal_encoding: int_enc)
+
+  p raw_text
+  p transcoded_text
+
+Output:
+
+  "R\xE9sum\xE9"
+  "Résumé"
+
+=== \Encoding Options
+
+A number of methods in the Ruby core accept keyword arguments as encoding options.
+
+Some of the options specify or utilize a _replacement_ _string_, to be used
+in certain transcoding operations.
+A replacement string may be in any encoding that can be converted
+to the encoding of the destination string.
+
+These keyword-value pairs specify encoding options:
+
+- For an invalid byte sequence:
+
+  - <tt>:invalid: nil</tt> (default): Raise exception.
+  - <tt>:invalid: :replace</tt>: Replace each invalid byte sequence
+    with the replacement string.
+
+  Examples:
+
+    s = "\x80foo\x80"
+    s.encode('ISO-8859-3') # Raises Encoding::InvalidByteSequenceError.
+    s.encode('ISO-8859-3', invalid: :replace) # => "?foo?"
+
+- For an undefined character:
+
+  - <tt>:undef: nil</tt> (default): Raise exception.
+  - <tt>:undef: :replace</tt>: Replace each undefined character
+    with the replacement string.
+
+  Examples:
+
+    s = "\x80foo\x80"
+    "\x80".encode('UTF-8', 'ASCII-8BIT') # Raises Encoding::UndefinedConversionError.
+    s.encode('UTF-8', 'ASCII-8BIT', undef: :replace) # => "�foo�"
+
+
+- Replacement string:
+
+  - <tt>:replace: nil</tt> (default): Set replacement string to default value:
+    <tt>"\uFFFD"</tt> ("�") for a Unicode encoding, <tt>'?'</tt> otherwise.
+  - <tt>:replace: _some_string_</tt>: Set replacement string to the given +some_string+;
+    overrides +:fallback+.
+
+  Examples:
+
+    s = "\xA5foo\xA5"
+    options = {:undef => :replace, :replace => 'xyzzy'}
+    s.encode('UTF-8', 'ISO-8859-3', **options) # => "xyzzyfooxyzzy"
+
+- Replacement fallback:
+
+  One of these may be specified:
+
+  - <tt>:fallback: nil</tt> (default): No replacement fallback.
+  - <tt>:fallback: _hash_like_object_</tt>: Set replacement fallback to the given
+    +hash_like_object+; the replacement string is <tt>_hash_like_object_[X]</tt>.
+  - <tt>:fallback: _method_</tt>: Set replacement fallback to the given
+    +method+; the replacement string is <tt>_method_(X)</tt>.
+  - <tt>:fallback: _proc_</tt>: Set replacement fallback to the given
+    +proc+; the replacement string is <tt>_proc_[X]</tt>.
+
+  Examples:
+
+    s = "\u3042foo\u3043"
+
+    hash = {"\u3042" => 'xyzzy'}
+    hash.default = 'XYZZY'
+    s.encode('ASCII', fallback: h) # => "xyzzyfooXYZZY"
+
+    def (fallback = "U+%.4X").escape(x)
+      self % x.unpack("U")
+    end
+    "\u{3042}".encode("US-ASCII", fallback: fallback.method(:escape)) # => "U+3042"
+
+    proc = Proc.new {|x| x == "\u3042" ? 'xyzzy' : 'XYZZY' }
+    s.encode('ASCII', fallback: proc) # => "XYZZYfooXYZZY"
+
+- XML entities:
+
+  One of these may be specified:
+
+  - <tt>:xml: nil</tt> (default): No handling for XML entities.
+  - <tt>:xml: :text</tt>: Treat source text as XML;
+    replace each undefined character
+    with its upper-case hexdecimal numeric character reference,
+    except that:
+
+    - <tt>&</tt> is replaced with <tt>&amp;</tt>.
+    - <tt><</tt> is replaced with <tt>&lt;</tt>.
+    - <tt>></tt> is replaced with <tt>&gt;</tt>.
+
+  - <tt>:xml: :attr</tt>: Treat source text as XML attribute value;
+    replace each undefined character
+    with its upper-case hexdecimal numeric character reference,
+    except that:
+
+    - The replacement string <tt>r</tt> is double-quoted (<tt>"r"</tt>).
+    - Each embedded double-quote is replaced with <tt>&quot;</tt>.
+    - <tt>&</tt> is replaced with <tt>&amp;</tt>.
+    - <tt><</tt> is replaced with <tt>&lt;</tt>.
+    - <tt>></tt> is replaced with <tt>&gt;</tt>.
+
+  Examples:
+
+    s = 'foo"<&>"bar' + "\u3042"
+    s.encode('ASCII', xml: :text) # => "foo\"&lt;&amp;&gt;\"bar&#x3042;"
+    s.encode('ASCII', xml: :attr) # => "\"foo&quot;&lt;&amp;&gt;&quot;bar&#x3042;\""
+
+
+- Newlines:
+
+  One of these may be specified:
+
+  - <tt>:cr_newline: true</tt>: Replace each line-feed character (<tt>"\n"</tt>)
+    with a carriage-return character (<tt>"\r"</tt>).
+  - <tt>:crlf_newline: true</tt>: Replace each line-feed character (<tt>"\n"</tt>)
+    with a carriage-return/line-feed string (<tt>"\r\n"</tt>).
+  - <tt>:universal_newline: true</tt>: Replace each carriage-return
+    character (<tt>"\r"</tt>) and each carriage-return/line-feed string
+    (<tt>"\r\n"</tt>) with a line-feed character (<tt>"\n"</tt>).
+
+  Examples:
+
+    s = "\n \r \r\n"                           # => "\n \r \r\n"
+    s.encode('ASCII', cr_newline: true)        # => "\r \r \r\r"
+    s.encode('ASCII', crlf_newline: true)      # => "\r\n \r \r\r\n"
+    s.encode('ASCII', universal_newline: true) # => "\n \n \n"

+= Rubyの拡張ライブラリの作り方
+
+Rubyの拡張ライブラリの作り方を説明します．
+
+== 基礎知識
+
+Cの変数には型があり，データには型がありません．ですから，た
+とえばポインタをintの変数に代入すると，その値は整数として取
+り扱われます．逆にRubyの変数には型がなく，データに型がありま
+す．この違いのため，CとRubyは相互に変換しなければ，お互いの
+データをアクセスできません．
+
+RubyのデータはVALUEというCの型で表現されます．VALUE型のデー
+タはそのデータタイプを自分で知っています．このデータタイプと
+いうのはデータ(オブジェクト)の実際の構造を意味していて，Ruby
+のクラスとはまた違ったものです．
+
+VALUEからCにとって意味のあるデータを取り出すためには
+
+1. VALUEのデータタイプを知る
+2. VALUEをCのデータに変換する
+
+の両方が必要です．(1)を忘れると間違ったデータの変換が行われ
+て，最悪プログラムがcore dumpします．
+
+=== データタイプ
+
+Rubyにはユーザが使う可能性のある以下のタイプがあります．
+
+T_NIL      :: nil
+T_OBJECT   :: 通常のオブジェクト
+T_CLASS    :: クラス
+T_MODULE   :: モジュール
+T_FLOAT    :: 浮動小数点数
+T_STRING   :: 文字列
+T_REGEXP   :: 正規表現
+T_ARRAY    :: 配列
+T_HASH     :: 連想配列
+T_STRUCT   :: (Rubyの)構造体
+T_BIGNUM   :: 多倍長整数
+T_FIXNUM   :: Fixnum(31bitまたは63bit長整数)
+T_COMPLEX  :: 複素数
+T_RATIONAL :: 有理数
+T_FILE     :: 入出力
+T_TRUE     :: 真
+T_FALSE    :: 偽
+T_DATA     :: データ
+T_SYMBOL   :: シンボル
+
+その他に内部で利用されている以下のタイプがあります．
+
+  T_ICLASS
+  T_MATCH
+  T_UNDEF
+  T_NODE
+  T_ZOMBIE
+
+ほとんどのタイプはCの構造体で実装されています．
+
+=== VALUEのデータタイプをチェックする
+
+ruby.hではTYPE()というマクロが定義されていて，VALUEのデータ
+タイプを知ることが出来ます．TYPE()マクロは上で紹介したT_XXXX
+の形式の定数を返します．VALUEのデータタイプに応じて処理する
+場合には，TYPE()の値で分岐することになります．
+
+  switch (TYPE(obj)) {
+    case T_FIXNUM:
+      /* FIXNUMの処理 */
+      break;
+    case T_STRING:
+      /* 文字列の処理 */
+      break;
+    case T_ARRAY:
+      /* 配列の処理 */
+      break;
+    default:
+      /* 例外を発生させる */
+      rb_raise(rb_eTypeError, "not valid value");
+      break;
+  }
+
+それとデータタイプをチェックして，正しくなければ例外を発生す
+る関数が用意されています．
+
+  void Check_Type(VALUE value, int type)
+
+この関数はvalueがtypeで無ければ，例外を発生させます．引数と
+して与えられたVALUEのデータタイプが正しいかどうかチェックす
+るためには，この関数を使います．
+
+FIXNUMとNILに関してはより高速な判別マクロが用意されています．
+
+  FIXNUM_P(obj)
+  NIL_P(obj)
+
+=== VALUEをCのデータに変換する
+
+データタイプがT_NIL，T_FALSE，T_TRUEである時，データはそれぞ
+れnil，false，trueです．このデータタイプのオブジェクトはひと
+つずつしか存在しません．
+
+データタイプがT_FIXNUMの時，これは31bitまたは63bitのサイズを
+持つ整数です．longのサイズが32bitのプラットフォームであれば
+31bitに，longのサイズが64bitのプラットフォームであれば63bit
+になります. FIXNUM を C の整数に変換するためにはマクロ
+「FIX2INT()」または「FIX2LONG()」を使います．これらのマクロ
+を使用する際には事前にデータタイプがFIXNUMであることを確認す
+る必要がありますが，比較的高速に変換を行うことができます．ま
+た，「FIX2LONG()」は例外を発生しませんが，「FIX2INT()」は変
+換結果がintのサイズに収まらない場合には例外を発生します．
+それから，FIXNUMに限らずRubyのデータを整数に変換する
+「NUM2INT()」および「NUM2LONG()」というマクロがあります．こ
+れらのマクロはデータタイプのチェック無しで使えます
+(整数に変換できない場合には例外が発生する)．同様にチェック無し
+で使える変換マクロはdoubleを取り出す「NUM2DBL()」があります．
+
+char* を取り出す場合， StringValue() と StringValuePtr()
+を使います．
+StringValue(var) は var が String
+であれば何もせず，そうでなければ var を var.to_str() の結果
+に置き換えるマクロ，StringValuePtr(var) は同様に var を
+String に置き換えてから var のバイト列表現に対する char* を
+返すマクロです．var の内容を直接置き換える処理が入るので，
+var は lvalue である必要があります．
+また，StringValuePtr() に類似した StringValueCStr() というマ
+クロもあります．StringValueCStr(var) は var を String に置き
+換えてから var の文字列表現に対する char* を返します．返され
+る文字列の末尾には NUL 文字が付加されます．なお，途中に NUL
+文字が含まれる場合は ArgumentError が発生します．
+一方，StringValuePtr() では，末尾に NUL 文字がある保証はなく，
+途中に NUL 文字が含まれている可能性もあります．
+
+それ以外のデータタイプは対応するCの構造体があります．対応す
+る構造体のあるVALUEはそのままキャスト(型変換)すれば構造体の
+ポインタに変換できます．
+
+構造体は「struct RXxxxx」という名前でruby.hで定義されていま
+す．例えば文字列は「struct RString」です．実際に使う可能性が
+あるのは文字列と配列くらいだと思います．
+
+ruby.hでは構造体へキャストするマクロも「RXXXXX()」(全部大文
+字にしたもの)という名前で提供されています(例: RSTRING())．た
+だし、構造体への直接のアクセスはできるだけ避け，対応する
+rb_xxxx() といった関数を使うようにして下さい．例えば，配列の
+要素へアクセスする場合は，rb_ary_entry(ary, offset)，
+rb_ary_store(ary, offset, obj) を利用するようにして下さい．
+
+構造体からデータを取り出すマクロが提供されています．文字列
+strの長さを得るためには「RSTRING_LEN(str)」とし，文字列strを
+char*として得るためには「RSTRING_PTR(str)」とします．
+
+Rubyの構造体を直接アクセスする時に気をつけなければならないこ
+とは，配列や文字列の構造体の中身は参照するだけで，直接変更し
+ないことです．直接変更した場合，オブジェクトの内容の整合性が
+とれなくなって，思わぬバグの原因になります．
+
+=== CのデータをVALUEに変換する
+
+VALUEの実際の構造は
+
+FIXNUMの場合 ::
+
+  1bit左シフトして，LSBを立てる．
+
+その他のポインタの場合 ::
+
+  そのままVALUEにキャストする．
+
+となっています．よって，LSBをチェックすればVALUEがFIXNUMかど
+うかわかるわけです(ポインタのLSBが立っていないことを仮定して
+いる)．
+
+ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE
+にキャストするだけでVALUEに変換出来ます．ただし，任意の構造
+体がVALUEにキャスト出来るわけではありません．キャストするの
+はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx
+のもの)だけです．
+
+FIXNUMに関しては変換マクロを経由する必要があります．Cの整数
+からVALUEに変換するマクロは以下のものがあります．必要に応じ
+て使い分けてください．
+
+INT2FIX() :: もとの整数が31bitまたは63bit以内に収まる自信
+             がある時
+INT2NUM() :: 任意の整数からVALUEへ
+
+INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換
+してくれます(が，少し遅い)．
+
+=== Rubyのデータを操作する
+
+先程も述べた通り，Rubyの構造体をアクセスする時に内容の更新を
+行うことは勧められません．で，Rubyのデータを操作する時には
+Rubyが用意している関数を用いてください．
+
+ここではもっとも使われるであろう文字列と配列の生成/操作を行
+う関数をあげます(全部ではないです)．
+
+==== 文字列に対する関数
+
+rb_str_new(const char *ptr, long len) ::
+
+  新しいRubyの文字列を生成する．
+
+rb_str_new2(const char *ptr) ::

+
+== Rubyの機能を使う
+
+原理的にRubyで書けることはCでも書けます．RubyそのものがCで記
+述されているんですから，当然といえば当然なんですけど．ここで
+はRubyの拡張に使うことが多いだろうと予測される機能を中心に紹
+介します．
+
+=== Rubyに機能を追加する
+
+Rubyで提供されている関数を使えばRubyインタプリタに新しい機能
+を追加することができます．Rubyでは以下の機能を追加する関数が
+提供されています．
+
+- クラス，モジュール
+- メソッド，特異メソッドなど
+- 定数
+
+では順に紹介します．
+
+==== クラス/モジュール定義
+
+クラスやモジュールを定義するためには，以下の関数を使います．
+
+  VALUE rb_define_class(const char *name, VALUE super)
+  VALUE rb_define_module(const char *name)
+
+これらの関数は新しく定義されたクラスやモジュールを返します．
+メソッドや定数の定義にこれらの値が必要なので，ほとんどの場合
+は戻り値を変数に格納しておく必要があるでしょう．
+
+クラスやモジュールを他のクラスの内部にネストして定義する時に
+は以下の関数を使います．
+
+  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
+  VALUE rb_define_module_under(VALUE outer, const char *name)
+
+==== メソッド/特異メソッド定義
+
+メソッドや特異メソッドを定義するには以下の関数を使います．
+
+  void rb_define_method(VALUE klass, const char *name,
+                        VALUE (*func)(ANYARGS), int argc)
+
+  void rb_define_singleton_method(VALUE object, const char *name,
+                                  VALUE (*func)(ANYARGS), int argc)
+
+念のため説明すると「特異メソッド」とは，その特定のオブジェク
+トに対してだけ有効なメソッドです．RubyではよくSmalltalkにお
+けるクラスメソッドとして，クラスに対する特異メソッドが使われ
+ます．
+
+これらの関数の argcという引数はCの関数へ渡される引数の数(と
+形式)を決めます．argcが0以上の時は関数に引き渡す引数の数を意
+味します．16個以上の引数は使えません(が，要りませんよね，そ
+んなに)．実際の関数には先頭の引数としてselfが与えられますの
+で，指定した数より1多い引数を持つことになります．
+
+argcが負の時は引数の数ではなく，形式を指定したことになります．
+argcが-1の時は引数を配列に入れて渡されます．argcが-2の時は引
+数はRubyの配列として渡されます．
+
+メソッドを定義する関数はまだいくつかあります. ひとつはメソッド
+名としてIDを取ります. IDについては2.2.2を参照.
+
+  void rb_define_method_id(VALUE klass, ID name,
+                           VALUE (*func)(ANYARGS), int argc)
+
+private/protectedなメソッドを定義するふたつの関数があります.
+
+  void rb_define_private_method(VALUE klass, const char *name,
+                                VALUE (*func)(ANYARGS), int argc)
+  void rb_define_protected_method(VALUE klass, const char *name,
+                                  VALUE (*func)(ANYARGS), int argc)
+
+privateメソッドとは関数形式でしか呼び出すことの出来ないメソッ
+ドです．
+
+最後に， rb_define_module関数はモジュール関数を定義します．
+モジュール関数とはモジュールの特異メソッドであり，同時に
+privateメソッドでもあるものです．例をあげるとMathモジュール
+のsqrt()などがあげられます．このメソッドは
+
+  Math.sqrt(4)
+
+という形式でも
+
+  include Math
+  sqrt(4)
+
+という形式でも使えます．モジュール関数を定義する関数は以下の
+通りです．
+
+  void rb_define_module_function(VALUE module, const char *name,
+                                 VALUE (*func)(ANYARGS), int argc)
+
+関数的メソッド(Kernelモジュールのprivate method)を定義するた
+めの関数は以下の通りです．
+
+  void rb_define_global_function(const char *name, VALUE (*func)(ANYARGS), int argc)
+
+メソッドの別名を定義するための関数は以下の通りです．
+
+  void rb_define_alias(VALUE module, const char* new, const char* old);
+
+属性の取得・設定メソッドを定義するには
+
+  void rb_define_attr(VALUE klass, const char *name, int read, int write)
+
+クラスメソッドallocateを定義したり削除したりするための関数は
+以下の通りです．
+
+  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
+  void rb_undef_alloc_func(VALUE klass);
+
+funcはクラスを引数として受け取って，新しく割り当てられたイン
+スタンスを返さなくてはなりません．このインスタンスは，外部リ
+ソースなどを含まない，できるだけ「空」のままにしておいたほう
+がよいでしょう．
+
+継承したクラスにある既存のメソッドをオーバーライドしているな
+ら，オーバーライドされたメソッドを呼び出すには以下の関数を使
+います．
+
+  VALUE rb_call_super(int argc, const VALUE *argv)
+
+現在のスコープのレシーバは(他に方法がなければ)，以下の関数で
+得ることができます．
+
+  VALUE rb_current_receiver(void)
+
+==== 定数定義
+
+拡張ライブラリが必要な定数はあらかじめ定義しておいた方が良い
+でしょう．定数を定義する関数は二つあります．
+
+  void rb_define_const(VALUE klass, const char *name, VALUE val)
+  void rb_define_global_const(const char *name, VALUE val)
+
+前者は特定のクラス/モジュールに属する定数を定義するもの，後
+者はグローバルな定数を定義するものです．
+
+=== Rubyの機能をCから呼び出す
+
+既に『1.5 Rubyのデータを操作する』で一部紹介したような関数を
+使えば，Rubyの機能を実現している関数を直接呼び出すことが出来
+ます．
+
+# このような関数の一覧表はいまのところありません．ソースを見
+# るしかないですね．
+
+それ以外にもRubyの機能を呼び出す方法はいくつかあります．
+
+==== Rubyのプログラムをevalする
+
+CからRubyの機能を呼び出すもっとも簡単な方法として，文字列で
+与えられたRubyのプログラムを評価する以下の関数があります．
+
+  VALUE rb_eval_string(const char *str)
+
+この評価は現在の環境で行われます．つまり，現在のローカル変数
+などを受け継ぎます．
+
+評価は例外を発生するかもしれないことに注意しましょう. より安全
+な関数もあります.
+
+  VALUE rb_eval_string_protect(const char *str, int *state)
+
+この関数はエラーが発生するとnilを返します．そして，成功時には
+*stateはゼロに，さもなくば非ゼロになります．
+
+==== IDまたはシンボル
+
+Cから文字列を経由せずにRubyのメソッドを呼び出すこともできま
+す．その前に，Rubyインタプリタ内でメソッドや変数名を指定する
+時に使われているIDについて説明しておきましょう．
+
+IDとは変数名，メソッド名を表す整数です．Rubyの中では
+
+ :識別子
+
+または
+
+ :"任意の文字列"
+
+でアクセスできます．Cからこの整数を得るためには関数
+
+  rb_intern(const char *name)
+  rb_intern_str(VALUE name)
+
+を使います．Rubyから引数として与えられたシンボル(または文字
+列)をIDに変換するには以下の関数を使います．
+
+  rb_to_id(VALUE symbol)
+  rb_check_id(volatile VALUE *name)
+  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
+
+もし引数がシンボルでも文字列でもなければ，to_strメソッドで文
+字列に変換しようとします．第二の関数はその変換結果を*nameに保
+存し,その名前が既知のシンボルでない場合は0を返します．この関
+数が0以外を返した場合は*nameは常にシンボルか文字列であり，0を
+返した場合は常に文字列です．第三の関数はRubyの文字列ではなく
+NUL終端されたCの文字列を使います．
+
+Rubyから引数として与えられたシンボル(または文字列)をシンボル
+に変換するには以下の関数を使います．
+
+  rb_to_symbol(VALUE name)
+  rb_check_symbol(volatile VALUE *namep)
+  rb_check_symbol_cstr(const char *ptr, long len, rb_encoding *enc)
+
+これらの関数は，IDの代わりにシンボルを返すことを除けば上記の
+関数と同じです．
+
+==== CからRubyのメソッドを呼び出す
+
+Cから文字列を経由せずにRubyのメソッドを呼び出すためには以下
+の関数を使います．
+
+  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
+
+この関数はオブジェクトrecvのmidで指定されるメソッドを呼び出
+します．その他に引数の指定の仕方が違う以下の関数もあります．
+
+  VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
+  VALUE rb_funcallv(VALUE recv, ID mid, int argc, VALUE *argv)
+  VALUE rb_apply(VALUE recv, ID mid, VALUE args)
+
+applyには引数としてRubyの配列を与えます．
+
+==== 変数/定数を参照/更新する
+
+Cから関数を使って参照・更新できるのは，定数，インスタンス変
+数です．大域変数は一部のものはCの大域変数としてアクセスでき
+ます．ローカル変数を参照する方法は公開していません．
+
+オブジェクトのインスタンス変数を参照・更新する関数は以下の通
+りです．
+
+  VALUE rb_ivar_get(VALUE obj, ID id)
+  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
+
+idはrb_intern()で得られるものを使ってください．
+
+定数を参照するには以下の関数を使ってください．
+
+  VALUE rb_const_get(VALUE obj, ID id)
+
+定数を新しく定義するためには『2.1.3 定数定義』で紹介さ
+れている関数を使ってください．
+
+== RubyとCとの情報共有
+
+C言語とRubyの間で情報を共有する方法について解説します．
+
+=== Cから参照できるRubyの定数
+
+以下のRubyの定数はCのレベルから参照できます．
+
+Qtrue ::
+Qfalse ::
+
+  真偽値．C言語から見た「true」と「false」．
+
+Qnil ::
+
+  C言語から見た「nil」．
+
+RTEST(obj)というマクロはobjがQfalseかQnilのとき0を返します．
+
+=== CとRubyで共有される大域変数
+
+CとRubyで大域変数を使って情報を共有できます．共有できる大域
+変数にはいくつかの種類があります．そのなかでもっとも良く使わ
+れると思われるのはrb_define_variable()です．
+
+  void rb_define_variable(const char *name, VALUE *var)
+
+この関数はRubyとCとで共有する大域変数を定義します．変数名が
+`$'で始まらない時には自動的に追加されます．この変数の値を変
+更すると自動的にRubyの対応する変数の値も変わります．
+
+またRuby側からは更新できない変数もあります．このread onlyの
+変数は以下の関数で定義します．
+
+  void rb_define_readonly_variable(const char *name, VALUE *var)
+
+これら変数の他にhookをつけた大域変数を定義できます．hook付き
+の大域変数は以下の関数を用いて定義します．hook付き大域変数の
+値の参照や設定はhookで行う必要があります．
+
+  void rb_define_hooked_variable(const char *name, VALUE *var,
+                                 VALUE (*getter)(), void (*setter)())
+
+この関数はCの関数によってhookのつけられた大域変数を定義しま
+す．変数が参照された時には関数getterが，変数に値がセットされ
+た時には関数setterが呼ばれる．hookを指定しない場合はgetterや
+setterに0を指定します．
+--
+getterもsetterも0ならばrb_define_variable()と同じになる．
+++
+
+getterとsetterの仕様は次の通りです．
+
+  VALUE (*getter)(ID id, VALUE *var);
+  void (*setter)(VALUE val, ID id, VALUE *var);
+
+それから，対応するCの変数を持たないRubyの大域変数を定義する
+こともできます. その変数の値はフック関数のみによって取得・設定
+されます.
+
+  void rb_define_virtual_variable(const char *name,
+                                  VALUE (*getter)(), void (*setter)())
+
+この関数によって定義されたRubyの大域変数が参照された時には
+getterが，変数に値がセットされた時にはsetterが呼ばれます．
+
+getterとsetterの仕様は以下の通りです．
+
+  (*getter)(ID id);
+  (*setter)(VALUE val, ID id);
+
+=== CのデータをRubyオブジェクトにする
+
+Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして
+取り扱いたい場合がありえます．このような場合はTypedData_XXX
+マクロ群を用いて構造体へのポインタとRubyのオブジェクトとを互
+いに変換できます．
+
+--
+古い(非Typedな)Data_XXXマクロ群は非推奨になりました．
+将来のバージョンのRubyでは古いマクロは動作しなくなる可能性
+があります．
+++
+
+==== 構造体からオブジェクトへ
+
+構造体へのポインタsvalをRubyオブジェクトに変換するには次のマ
+クロを使います。
+
+  TypedData_Wrap_Struct(klass, data_type, sval)
+
+このマクロの戻り値は生成されたオブジェクトを表すVALUE値です．
+
+klassはこのオブジェクトのクラスです．klassは, Objectクラスか
+ら派生し, 必ずrb_define_alloc_funcかrb_undef_alloc_funcを呼
+び出してallocatorを設定してください．
+
+data_typeはこの構造体をRubyが管理するための情報を記述した
+const rb_data_type_t型へのポインタです．
+
+rb_data_type_tは次のように定義されています．
+
+  typedef struct rb_data_type_struct rb_data_type_t;
+
+  struct rb_data_type_struct {
+      const char *wrap_struct_name;
+      struct {
+          void (*dmark)(void*);
+          void (*dfree)(void*);
+          size_t (*dsize)(const void *);
+          void *reserved[2];
+      } function;
+      const rb_data_type_t *parent;
+      void *data;
+      VALUE flags;
+  };
+
+wrap_struct_nameはこの構造体を識別する名前です．主に統計情報
+の収集と出力に用いられます．プロセス内で一意であれば特にCや
+Rubyの識別子として有効である必要はありません．
+
+dmarkおよびdfree関数はGC実行中に呼び出されます.
+なお, GC実行中はRubyオブジェクトのアロケーションは禁止されま
+す. よって, dmarkおよびdfree関数でRubyオブジェクトのアロケー
+ションは行わないでください.
+
+dmarkはガーベージコレクタがオブジェクトへの参照をマークする
+ときに用いる関数です．この構造体がRubyのオブジェクトへの参照
+を保持するときには, dmarkではrb_gc_markなどを用いて構造体内
+のすべての参照をマークしなければなりません．
+そのような参照を含まない時には0を指定します．
+
+--
+そのような参照は勧められません．
+++
+
+dfreeはこの構造体がもう不要になった時に呼ばれる関数です．こ
+の関数がガーベージコレクタから呼ばれます．これが
+RUBY_DEFAULT_FREEの場合は，単純に構造体が解放されます．
+
+dsizeは構造体が消費しているメモリのバイト数を返す関数です．
+引数として構造体へのポインタが渡されます．実装困難であれば0
+を渡しても差し支えありませんが, できるだけ指定するようにして
+ください．
+
+reservedとparentは0で埋めなければなりません．
+
+dataにはユーザー定義の任意の値を指定できます．Rubyはこの値に
+は関知しないので，好きに使ってください．
+
+flagsには次のフラグのうち当てはまるもののビット和を指定しま
+す．いずれもRubyのガーベージコレクタについての深い理解を必要
+としますので，良くわからない場合には0を指定すると良いでしょ
+う．
+
+RUBY_TYPED_FREE_IMMEDIATELY ::
+
+  このフラグを指定すると，ガーベージコレクタはこの構造体が不
+  要になった場合にはGC中に直ちにdfreeを呼び出します．
+  dfreeがRuby内部のロック(GVL)を解放する可能性がない場合はこ
+  のフラグを指定できます．
+
+  指定しない場合はdfree呼び出しは遅延され, ファイナライザと
+  同じタイミングで実行されます．
+
+RUBY_TYPED_WB_PROTECTED ::
+
+  オブジェクトの実装がライトバリアをサポートしていることを示
+  します．このフラグを指定するとRubyはそのオブジェクトに対し
+  てGCをより効率的に実行できます．
+  ただし，指定する場合はユーザーはそのオブジェクトのすべての
+  メソッドの実装に適切にライトバリアを挿入する責任があります．
+  さもなくばRubyは実行時にクラッシュする可能性があります．
+
+  ライトバリアについてはdoc/extension.ja.rdocのAppendix D
+  "世代別GC"も参照してください．
+
+
+Cの構造体の割当と対応するオブジェクトの生成を同時に行うマク
+ロとして以下のものが提供されています．
+
+  TypedData_Make_Struct(klass, type, data_type, sval)
+
+このマクロの戻り値は生成されたオブジェクトのVALUE値
+です．このマクロは以下の式のように働きます:
+
+  (sval = ZALLOC(type), TypedData_Wrap_Struct(klass, data_type, sval))
+
+klass, data_typeはData_Wrap_Structと同じ働きをします．type
+は割り当てるC構造体の型です．割り当てられた構造体は変数sval
+に代入されます．この変数の型は (type*) である必要があります．
+
+==== オブジェクトから構造体へ
+
+TypedData_Wrap_StructやTypedData_Make_Structで生成したオブジェ
+クトから構造体へのポインタを復元するには以下のマクロを用いま
+す．
+
+  TypedData_Get_Struct(obj, type, &data_type, sval)
+
+Cの構造体へのポインタは変数svalに代入されます．
+
+これらのマクロの使い方はちょっと分かりにくいので，後で説明す
+る例題を参照してください．
+
+== 例: dbmの拡張ライブラリの作成
+
+=== ディレクトリを作る
+
+  % mkdir ext/dbm
+
+Ruby 1.1からは任意のディレクトリでダイナミックライブラリを作
+ることができるようになりました．Rubyに静的にリンクする場合に
+はRubyを展開したディレクトリの下，extディレクトリの中に拡張
+ライブラリ用のディレクトリを作る必要があります．名前は適当に
+選んで構いません．
+
+=== 設計する
+
+まあ，当然なんですけど，どういう機能を実現するかどうかまず設
+計する必要があります．どんなクラスをつくるか，そのクラスには
+どんなメソッドがあるか，クラスが提供する定数などについて設計
+します．
+
+=== Cコードを書く
+
+拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー
+スがひとつの時には「ライブラリ名.c」を選ぶと良いでしょう．C
+言語のソースが複数の場合には逆に「ライブラリ名.c」というファ
+イル名は避ける必要があります．オブジェクトファイルとモジュー
+ル生成時に中間的に生成される「ライブラリ名.o」というファイル
+とが衝突するからです．また，後述する mkmf ライブラリのいくつ
+かの関数がコンパイルを要するテストのために「conftest.c」とい
+うファイル名を使用することに注意してください．ソースファイル
+名として「conftest.c」を使用してはなりません．
+
+Rubyは拡張ライブラリをロードする時に「Init_ライブラリ名」と
+いう関数を自動的に実行します．dbmライブラリの場合「Init_dbm」
+です．この関数の中でクラス，モジュール，メソッド，定数などの
+定義を行います．dbm.cから一部引用します．
+
+  void
+  Init_dbm(void)
+  {
+      /* DBMクラスを定義する */
+      VALUE cDBM = rb_define_class("DBM", rb_cObject);
+      /* DBMはEnumerableモジュールをインクルードする */
+      rb_include_module(cDBM, rb_mEnumerable);
+
+      /* DBMクラスのクラスメソッドopen(): 引数はCの配列で受ける */
+      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
+
+      /* DBMクラスのメソッドclose(): 引数はなし */
+      rb_define_method(cDBM, "close", fdbm_close, 0);
+      /* DBMクラスのメソッド[]: 引数は1個 */
+      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
+
+      /* ... */
+
+      /* DBMデータを格納するインスタンス変数名のためのID */
+      id_dbm = rb_intern("dbm");
+  }
+
+DBMライブラリはdbmのデータと対応するオブジェクトになるはずで
+すから，Cの世界のdbmをRubyの世界に取り込む必要があります．
+
+dbm.cではTypedData_Make_Structを以下のように使っています．
+
+  struct dbmdata {
+      int  di_size;
+      DBM *di_dbm;
+  };
+
+  static const rb_data_type_t dbm_type = {
+      "dbm",
+      {0, free_dbm, memsize_dbm,},
+      0, 0,
+      RUBY_TYPED_FREE_IMMEDIATELY,
+  };
+
+  obj = TypedData_Make_Struct(klass, struct dbmdata, &dbm_type, dbmp);
+
+ここではdbmdata構造体へのポインタをDataにカプセル化してい
+ます．DBM*を直接カプセル化しないのはclose()した時の処理を考
+えてのことです．
+
+Dataオブジェクトからdbmstruct構造体のポインタを取り出すため
+に以下のマクロを使っています．
+
+  #define GetDBM(obj, dbmp) do {\
+      TypedData_Get_Struct((obj), struct dbmdata, &dbm_type, (dbmp));\
+      if ((dbmp) == 0) closed_dbm();\
+      if ((dbmp)->di_dbm == 0) closed_dbm();\
+  } while (0)
+
+ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ
+の取り出しと，closeされているかどうかのチェックをまとめてい
+るだけです．
+
+DBMクラスにはたくさんメソッドがありますが，分類すると3種類の
+引数の受け方があります．ひとつは引数の数が固定のもので，例と
+してはdeleteメソッドがあります．deleteメソッドを実装している
+fdbm_delete()はこのようになっています．
+
+  static VALUE
+  fdbm_delete(VALUE obj, VALUE keystr)
+  {
+      /* ... */
+  }
+
+引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド
+の引数となります．
+
+引数の数が不定のものはCの配列で受けるものとRubyの配列で受け
+るものとがあります．dbmライブラリの中で，Cの配列で受けるもの
+はDBMのクラスメソッドであるopen()です．これを実装している関
+数fdbm_s_open()はこうなっています．
+
+  static VALUE
+  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
+  {
+      /* ... */
+
+      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
+          mode = 0666;          /* default value */
+      }
+
+      /* ... */
+  }
+
+このタイプの関数は第1引数が与えられた引数の数，第2引数が与え
+られた引数の入っている配列になります．selfは第3引数として与
+えられます．
+
+この配列で与えられた引数を解析するための関数がopen()でも使わ
+れているrb_scan_args()です．第3引数に指定したフォーマットに従
+い，第4引数以降に指定したVALUEへの参照に値を代入してくれま
+す．
+
+引数の数をチェックするだけならrb_check_arity()が使えます．
+これは引数をリストとして扱いたいときに便利です．
+
+引数をRubyの配列として受け取るメソッドの例には
+Thread#initializeがあります．実装はこうです．
+
+  static VALUE
+  thread_initialize(VALUE thread, VALUE args)
+  {
+      /* ... */
+  }
+
+第1引数はself，第2引数はRubyの配列です．
+
+*注意事項*
+
+Rubyと共有はしないがRubyのオブジェクトを格納する可能性のある
+Cの大域変数は以下の関数を使ってRubyインタプリタに変数の存在
+を教えてあげてください．でないとGCでトラブルを起こします．
+
+  void rb_global_variable(VALUE *var)
+
+=== extconf.rbを用意する
+
+Makefileを作る場合の雛型になるextconf.rbというファイルを作り
+ます．extconf.rbはライブラリのコンパイルに必要な条件のチェッ
+クなどを行うことが目的です．まず，
+
+  require 'mkmf'
+
+をextconf.rbの先頭に置きます．extconf.rbの中では以下のRuby関
+数を使うことが出来ます．
+
+  have_library(lib, func): ライブラリの存在チェック
+  have_func(func, header): 関数の存在チェック
+  have_header(header): ヘッダファイルの存在チェック
+  create_makefile(target[, target_prefix]): Makefileの生成
+
+以下の変数を使うことができます．
+
+  $CFLAGS: コンパイル時に追加的に指定するフラグ(-Oなど)
+  $CPPFLAGS: プリプロセッサに追加的に指定するフラグ(-Iや-Dなど)
+  $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど)
+  $objs: リンクされるオブジェクトファイル名のリスト
+
+オブジェクトファイルのリストは，通常はソースファイルを検索し
+て自動的に生成されますが，makeの途中でソースを生成するような
+場合は明示的に指定する必要があります．
+
+ライブラリをコンパイルする条件が揃わず，そのライブラリをコン
+パイルしない時にはcreate_makefileを呼ばなければMakefileは生
+成されず，コンパイルも行われません．
+
+=== dependを用意する
+
+もし，ディレクトリにdependというファイルが存在すれば，
+Makefileが依存関係をチェックしてくれます．
+
+  % gcc -MM *.c > depend
+
+などで作ることが出来ます．あって損は無いでしょう．
+
+=== Makefileを生成する
+
+Makefileを実際に生成するためには
+
+  ruby extconf.rb
+
+とします．extconf.rbに require 'mkmf' の行がない場合にはエラー
+になりますので，引数を追加して
+
+  ruby -r mkmf extconf.rb
+
+としてください．
+
+site_ruby ディレクトリでなく，
+vendor_ruby ディレクトリにインストールする場合には
+以下のように --vendor オプションを加えてください．
+
+  ruby extconf.rb --vendor
+
+ディレクトリをext以下に用意した場合にはRuby全体のmakeの時に
+自動的にMakefileが生成されますので，このステップは不要です．
+
+=== makeする
+
+動的リンクライブラリを生成する場合にはその場でmakeしてくださ
+い．必要であれば make install でインストールされます．
+
+ext以下にディレクトリを用意した場合は，Rubyのディレクトリで
+makeを実行するとMakefileを生成からmake，必要によってはそのモ
+ジュールのRubyへのリンクまで自動的に実行してくれます．
+extconf.rbを書き換えるなどしてMakefileの再生成が必要な時はま
+たRubyディレクトリでmakeしてください．
+
+拡張ライブラリはmake installでRubyライブラリのディレクトリの
+下にコピーされます．もし拡張ライブラリと協調して使うRubyで記
+述されたプログラムがあり，Rubyライブラリに置きたい場合には，
+拡張ライブラリ用のディレクトリの下に lib というディレクトリ
+を作り，そこに 拡張子 .rb のファイルを置いておけば同時にイン
+ストールされます．
+
+=== デバッグ
+
+まあ，デバッグしないと動かないでしょうね．ext/Setupにディレ
+クトリ名を書くと静的にリンクするのでデバッガが使えるようにな
+ります．その分コンパイルが遅くなりますけど．
+
+=== できあがり
+
+後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお
+使いください．Rubyの作者は拡張ライブラリに関して一切の権利を
+主張しません．

+
+<tt>$repo_root/include/ruby</tt>以下はすべて<tt>make

+
+  フォーマットが"12"の場合，引数は最低1つで，3つ(1+2)まで許さ
+  れるという意味になります．従って，フォーマット文字列に続い
+  て3つのVALUEへの参照を置く必要があります．それらには取得した
+  変数がセットされます．変数への参照の代わりにNULLを指定する
+  こともでき，その場合は取得した引数の値は捨てられます．なお，
+  省略可能引数が省略された時の変数の値はnil(C言語のレベルでは
+  Qnil)になります．

+  返り値は与えられた引数の数です．オプションハッシュおよびイ
+  テレータブロックは数えません．

+  キーワードです．必須キーワードがkeyword_hash中にない場合，
+  "missing keyword"ArgumentErrorが発生します．省略可能キーワー

+
+VALUE rb_ensure(VALUE (*func1)(ANYARGS), VALUE arg1, VALUE (*func2)(ANYARGS), VALUE arg2) ::
+
+  関数func1をarg1を引数として実行し, 実行終了後(たとえ例外が

+
+  関数funcをargを引数として実行し, 例外が発生しなければその戻
+  り値を返す．例外が発生した場合は, *stateに非0をセットして
+  Qnilを返す．

+== Appendix D. 世代別GC
+

+RGenGCは，過去の拡張ライブラリに（ほぼ）互換性を保つように開発されている
+ため，拡張ライブラリ側の対応はほぼ不要です．
+
+ただし，対応をすることで性能を向上することができる可能性があります．もし
+拡張ライブラリに高い性能が必要である場合は対応を検討して下さい．
+
+とくにRARRAY_PTR()/RHASH_TBL()のようなマクロを用いてポインタに直接アクセ
+スするようなコードは書かないようにして下さい．代わりに，rb_ary_aref(),
+rb_ary_store() などの，適切な API 関数を利用するようにして下さい．
+
+そのほか，対応についての詳細は extension.rdoc の「Appendix D. Generational
+GC」を参照して下さい．
+
+== Appendix E. Ractor サポート
+
+Ruby 3.0 から、Ruby プログラムを並列に実行するための仕組みである Ractor
+が導入されました。適切に並列に実行するためには、Ractor サポートが必要に
+なります。サポートしていないライブラリは、メイン Ractor 以外で実行すると
+エラーになります（Ractor::UnsafeError）。
+
+Ractor をサポートするための詳細は、extension.rdoc の「Appendix F. Ractor

+= Creating Extension Libraries for Ruby
+
+This document explains how to make extension libraries for Ruby.
+
+== Basic Knowledge
+
+In C, variables have types and data do not have types.  In contrast,
+Ruby variables do not have a static type, and data themselves have
+types, so data will need to be converted between the languages.
+
+Data in Ruby are represented by the C type `VALUE'.  Each VALUE data
+has its data type.
+
+To retrieve C data from a VALUE, you need to:
+
+1. Identify the VALUE's data type
+2. Convert the VALUE into C data
+
+Converting to the wrong data type may cause serious problems.
+
+=== Data Types
+
+The Ruby interpreter has the following data types:
+
+T_NIL       :: nil
+T_OBJECT    :: ordinary object
+T_CLASS     :: class
+T_MODULE    :: module
+T_FLOAT     :: floating point number
+T_STRING    :: string
+T_REGEXP    :: regular expression
+T_ARRAY     :: array
+T_HASH      :: associative array
+T_STRUCT    :: (Ruby) structure
+T_BIGNUM    :: multi precision integer
+T_FIXNUM    :: Fixnum(31bit or 63bit integer)
+T_COMPLEX   :: complex number
+T_RATIONAL  :: rational number
+T_FILE      :: IO
+T_TRUE      :: true
+T_FALSE     :: false
+T_DATA      :: data
+T_SYMBOL    :: symbol
+
+In addition, there are several other types used internally:
+
+T_ICLASS    :: included module
+T_MATCH     :: MatchData object
+T_UNDEF     :: undefined
+T_NODE      :: syntax tree node
+T_ZOMBIE    :: object awaiting finalization
+
+Most of the types are represented by C structures.
+
+=== Check Data Type of the VALUE
+
+The macro TYPE() defined in ruby.h shows the data type of the VALUE.
+TYPE() returns the constant number T_XXXX described above.  To handle
+data types, your code will look something like this:
+
+  switch (TYPE(obj)) {
+    case T_FIXNUM:
+      /* process Fixnum */
+      break;
+    case T_STRING:
+      /* process String */
+      break;
+    case T_ARRAY:
+      /* process Array */
+      break;
+    default:
+      /* raise exception */
+      rb_raise(rb_eTypeError, "not valid value");
+      break;
+  }
+
+There is the data type check function
+
+  void Check_Type(VALUE value, int type)
+
+which raises an exception if the VALUE does not have the type
+specified.
+
+There are also faster check macros for fixnums and nil.
+
+  FIXNUM_P(obj)
+  NIL_P(obj)
+
+=== Convert VALUE into C Data
+
+The data for type T_NIL, T_FALSE, T_TRUE are nil, false, true
+respectively.  They are singletons for the data type.
+The equivalent C constants are: Qnil, Qfalse, Qtrue.
+RTEST() will return true if a VALUE is neither Qfalse nor Qnil.
+If you need to differentiate Qfalse from Qnil,
+specifically test against Qfalse.
+
+The T_FIXNUM data is a 31bit or 63bit length fixed integer.
+This size depends on the size of long: if long is 32bit then
+T_FIXNUM is 31bit, if long is 64bit then T_FIXNUM is 63bit.
+T_FIXNUM can be converted to a C integer by using the
+FIX2INT() macro or FIX2LONG().  Though you have to check that the
+data is really FIXNUM before using them, they are faster.  FIX2LONG()
+never raises exceptions, but FIX2INT() raises RangeError if the
+result is bigger or smaller than the size of int.
+There are also NUM2INT() and NUM2LONG() which converts any Ruby
+numbers into C integers.  These macros include a type check,
+so an exception will be raised if the conversion failed.  NUM2DBL()
+can be used to retrieve the double float value in the same way.
+
+You can use the macros
+StringValue() and StringValuePtr() to get a char* from a VALUE.
+StringValue(var) replaces var's value with the result of "var.to_str()".
+StringValuePtr(var) does the same replacement and returns the char*
+representation of var.  These macros will skip the replacement if var
+is a String.  Notice that the macros take only the lvalue as their
+argument, to change the value of var in place.
+
+You can also use the macro named StringValueCStr(). This is just
+like StringValuePtr(), but always adds a NUL character at the end of
+the result. If the result contains a NUL character, this macro causes
+the ArgumentError exception.
+StringValuePtr() doesn't guarantee the existence of a NUL at the end
+of the result, and the result may contain NUL.
+
+Other data types have corresponding C structures, e.g. struct RArray
+for T_ARRAY etc. The VALUE of the type which has the corresponding
+structure can be cast to retrieve the pointer to the struct.  The
+casting macro will be of the form RXXXX for each data type; for
+instance, RARRAY(obj).  See "ruby.h".  However, we do not recommend
+to access RXXXX data directly because these data structures are complex.
+Use corresponding rb_xxx() functions to access the internal struct.
+For example, to access an entry of array, use rb_ary_entry(ary, offset)
+and rb_ary_store(ary, offset, obj).
+
+There are some accessing macros for structure members, for example
+`RSTRING_LEN(str)' to get the size of the Ruby String object.  The
+allocated region can be accessed by `RSTRING_PTR(str)'.
+
+Notice: Do not change the value of the structure directly, unless you
+are responsible for the result.  This ends up being the cause of
+interesting bugs.
+
+=== Convert C Data into VALUE
+
+To convert C data to Ruby values:
+
+FIXNUM ::
+
+  left shift 1 bit, and turn on its least significant bit (LSB).
+
+Other pointer values ::
+
+  cast to VALUE.
+
+You can determine whether a VALUE is a pointer or not by checking its LSB.
+
+Notice: Ruby does not allow arbitrary pointer values to be a VALUE.  They
+should be pointers to the structures which Ruby knows about.  The known
+structures are defined in <ruby.h>.
+
+To convert C numbers to Ruby values, use these macros:
+
+INT2FIX() :: for integers within 31bits.
+INT2NUM() :: for arbitrary sized integers.
+
+INT2NUM() converts an integer into a Bignum if it is out of the FIXNUM
+range, but is a bit slower.
+
+=== Manipulating Ruby Data
+
+As I already mentioned, it is not recommended to modify an object's
+internal structure.  To manipulate objects, use the functions supplied
+by the Ruby interpreter. Some (not all) of the useful functions are
+listed below:
+
+==== String Functions
+
+rb_str_new(const char *ptr, long len) ::
+
+  Creates a new Ruby string.
+
+rb_str_new2(const char *ptr) ::
+rb_str_new_cstr(const char *ptr) ::
+
+  Creates a new Ruby string from a C string.  This is equivalent to
+  rb_str_new(ptr, strlen(ptr)).
+
+rb_str_new_literal(const char *ptr) ::
+
+  Creates a new Ruby string from a C string literal.
+
+rb_sprintf(const char *format, ...) ::
+rb_vsprintf(const char *format, va_list ap) ::
+
+  Creates a new Ruby string with printf(3) format.
+
+  Note: In the format string, "%"PRIsVALUE can be used for Object#to_s
+  (or Object#inspect if '+' flag is set) output (and related argument
+  must be a VALUE).  Since it conflicts with "%i", for integers in
+  format strings, use "%d".
+
+rb_str_append(VALUE str1, VALUE str2) ::
+
+  Appends Ruby string str2 to Ruby string str1.
+
+rb_str_cat(VALUE str, const char *ptr, long len) ::
+
+  Appends len bytes of data from ptr to the Ruby string.
+
+rb_str_cat2(VALUE str, const char* ptr) ::
+rb_str_cat_cstr(VALUE str, const char* ptr) ::
+
+  Appends C string ptr to Ruby string str.  This function is
+  equivalent to rb_str_cat(str, ptr, strlen(ptr)).
+
+rb_str_catf(VALUE str, const char* format, ...) ::
+rb_str_vcatf(VALUE str, const char* format, va_list ap) ::
+
+  Appends C string format and successive arguments to Ruby string
+  str according to a printf-like format.  These functions are
+  equivalent to rb_str_append(str, rb_sprintf(format, ...)) and
+  rb_str_append(str, rb_vsprintf(format, ap)), respectively.
+
+rb_enc_str_new(const char *ptr, long len, rb_encoding *enc) ::
+rb_enc_str_new_cstr(const char *ptr, rb_encoding *enc) ::
+
+  Creates a new Ruby string with the specified encoding.
+
+rb_enc_str_new_literal(const char *ptr, rb_encoding *enc) ::
+
+  Creates a new Ruby string from a C string literal with the specified
+  encoding.
+
+rb_usascii_str_new(const char *ptr, long len) ::
+rb_usascii_str_new_cstr(const char *ptr) ::
+
+  Creates a new Ruby string with encoding US-ASCII.
+
+rb_usascii_str_new_literal(const char *ptr) ::
+
+  Creates a new Ruby string from a C string literal with encoding
+  US-ASCII.
+
+rb_utf8_str_new(const char *ptr, long len) ::
+rb_utf8_str_new_cstr(const char *ptr) ::
+
+  Creates a new Ruby string with encoding UTF-8.
+
+rb_utf8_str_new_literal(const char *ptr) ::
+
+  Creates a new Ruby string from a C string literal with encoding
+  UTF-8.
+
+rb_str_resize(VALUE str, long len) ::
+
+  Resizes a Ruby string to len bytes.  If str is not modifiable, this
+  function raises an exception.  The length of str must be set in
+  advance.  If len is less than the old length the content beyond
+  len bytes is discarded, else if len is greater than the old length
+  the content beyond the old length bytes will not be preserved but
+  will be garbage.  Note that RSTRING_PTR(str) may change by calling
+  this function.
+
+rb_str_set_len(VALUE str, long len) ::
+
+  Sets the length of a Ruby string.  If str is not modifiable, this
+  function raises an exception.  This function preserves the content
+  up to len bytes, regardless RSTRING_LEN(str).  len must not exceed
+  the capacity of str.
+
+rb_str_modify(VALUE str) ::
+
+  Prepares a Ruby string to modify.  If str is not modifiable, this
+  function raises an exception, or if the buffer of str is shared,
+  this function allocates new buffer to make it unshared.  Always
+  you MUST call this function before modifying the contents using
+  RSTRING_PTR and/or rb_str_set_len.
+
+==== Array Functions

+rb_ary_new() ::
+
+  Creates an array with no elements.
+
+rb_ary_new2(long len) ::
+rb_ary_new_capa(long len) ::
+
+  Creates an array with no elements, allocating internal buffer
+  for len elements.
+
+rb_ary_new3(long n, ...) ::
+rb_ary_new_from_args(long n, ...) ::
+
+  Creates an n-element array from the arguments.

+
+  Creates an n-element array from a C array.
+
+rb_ary_to_ary(VALUE obj) ::
+
+  Converts the object into an array.
+  Equivalent to Object#to_ary.
+
+There are many functions to operate an array.  They may dump core if other

+  Appends len elements of objects from ptr to the array.
+
+== Extending Ruby with C
+
+=== Adding New Features to Ruby
+
+You can add new features (classes, methods, etc.) to the Ruby
+interpreter.  Ruby provides APIs for defining the following things:
+
+- Classes, Modules
+- Methods, Singleton Methods
+- Constants
+
+==== Class and Module Definition
+
+To define a class or module, use the functions below:
+
+  VALUE rb_define_class(const char *name, VALUE super)
+  VALUE rb_define_module(const char *name)
+
+These functions return the newly created class or module.  You may
+want to save this reference into a variable to use later.
+
+To define nested classes or modules, use the functions below:
+
+  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
+  VALUE rb_define_module_under(VALUE outer, const char *name)
+
+==== Method and Singleton Method Definition
+
+To define methods or singleton methods, use these functions:
+
+  void rb_define_method(VALUE klass, const char *name,
+                        VALUE (*func)(ANYARGS), int argc)
+
+  void rb_define_singleton_method(VALUE object, const char *name,
+                                  VALUE (*func)(ANYARGS), int argc)
+
+The `argc' represents the number of the arguments to the C function,
+which must be less than 17.  But I doubt you'll need that many.
+
+If `argc' is negative, it specifies the calling sequence, not number of
+the arguments.
+
+If argc is -1, the function will be called as:
+
+  VALUE func(int argc, VALUE *argv, VALUE obj)
+
+where argc is the actual number of arguments, argv is the C array of
+the arguments, and obj is the receiver.
+
+If argc is -2, the arguments are passed in a Ruby array. The function
+will be called like:
+
+  VALUE func(VALUE obj, VALUE args)
+
+where obj is the receiver, and args is the Ruby array containing
+actual arguments.
+
+There are some more functions to define methods. One takes an ID
+as the name of method to be defined. See also ID or Symbol below.
+
+  void rb_define_method_id(VALUE klass, ID name,
+                           VALUE (*func)(ANYARGS), int argc)
+
+There are two functions to define private/protected methods:
+
+  void rb_define_private_method(VALUE klass, const char *name,
+                                VALUE (*func)(ANYARGS), int argc)
+  void rb_define_protected_method(VALUE klass, const char *name,
+                                  VALUE (*func)(ANYARGS), int argc)
+
+At last, rb_define_module_function defines a module function,
+which are private AND singleton methods of the module.
+For example, sqrt is a module function defined in the Math module.
+It can be called in the following way:
+
+  Math.sqrt(4)
+
+or
+
+  include Math
+  sqrt(4)
+
+To define module functions, use:
+
+  void rb_define_module_function(VALUE module, const char *name,
+                                 VALUE (*func)(ANYARGS), int argc)
+
+In addition, function-like methods, which are private methods defined
+in the Kernel module, can be defined using:
+
+  void rb_define_global_function(const char *name, VALUE (*func)(ANYARGS), int argc)
+
+To define an alias for the method,
+
+  void rb_define_alias(VALUE module, const char* new, const char* old);
+
+To define a reader/writer for an attribute,
+
+  void rb_define_attr(VALUE klass, const char *name, int read, int write)
+
+To define and undefine the `allocate' class method,
+
+  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
+  void rb_undef_alloc_func(VALUE klass);
+
+func has to take the klass as the argument and return a newly
+allocated instance.  This instance should be as empty as possible,
+without any expensive (including external) resources.
+
+If you are overriding an existing method of any ancestor of your class,
+you may rely on:
+
+  VALUE rb_call_super(int argc, const VALUE *argv)
+
+To specify whether keyword arguments are passed when calling super:
+
+  VALUE rb_call_super_kw(int argc, const VALUE *argv, int kw_splat)
+
++kw_splat+ can have these possible values (used by all methods that accept
++kw_splat+ argument):
+
+RB_NO_KEYWORDS :: Do not pass keywords
+RB_PASS_KEYWORDS :: Pass keywords, final argument should be a hash of keywords
+RB_PASS_CALLED_KEYWORDS :: Pass keywords if current method was called with
+                           keywords, useful for argument delegation
+
+To achieve the receiver of the current scope (if no other way is
+available), you can use:
+
+  VALUE rb_current_receiver(void)
+
+==== Constant Definition
+
+We have 2 functions to define constants:
+
+  void rb_define_const(VALUE klass, const char *name, VALUE val)
+  void rb_define_global_const(const char *name, VALUE val)
+
+The former is to define a constant under specified class/module.  The
+latter is to define a global constant.
+
+=== Use Ruby Features from C
+
+There are several ways to invoke Ruby's features from C code.
+
+==== Evaluate Ruby Programs in a String
+
+The easiest way to use Ruby's functionality from a C program is to
+evaluate the string as Ruby program.  This function will do the job:
+
+  VALUE rb_eval_string(const char *str)
+
+Evaluation is done under the current context, thus current local variables
+of the innermost method (which is defined by Ruby) can be accessed.
+
+Note that the evaluation can raise an exception. There is a safer
+function:
+
+  VALUE rb_eval_string_protect(const char *str, int *state)
+
+It returns nil when an error occurred. Moreover, *state is zero if str was
+successfully evaluated, or nonzero otherwise.
+
+==== ID or Symbol
+
+You can invoke methods directly, without parsing the string.  First I
+need to explain about ID.  ID is the integer number to represent
+Ruby's identifiers such as variable names.  The Ruby data type
+corresponding to ID is Symbol.  It can be accessed from Ruby in the
+form:
+
+  :Identifier
+
+or
+
+  :"any kind of string"
+
+You can get the ID value from a string within C code by using
+
+  rb_intern(const char *name)
+  rb_intern_str(VALUE name)
+
+You can retrieve ID from Ruby object (Symbol or String) given as an
+argument by using
+
+  rb_to_id(VALUE symbol)
+  rb_check_id(volatile VALUE *name)
+  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
+
+These functions try to convert the argument to a String if it was not
+a Symbol nor a String.  The second function stores the converted
+result into *name, and returns 0 if the string is not a known symbol.
+After this function returned a non-zero value, *name is always a
+Symbol or a String, otherwise it is a String if the result is 0.
+The third function takes NUL-terminated C string, not Ruby VALUE.
+
+You can retrieve Symbol from Ruby object (Symbol or String) given as
+an argument by using
+
+  rb_to_symbol(VALUE name)
+  rb_check_symbol(volatile VALUE *namep)
+  rb_check_symbol_cstr(const char *ptr, long len, rb_encoding *enc)
+
+These functions are similar to above functions except that these
+return a Symbol instead of an ID.
+
+You can convert C ID to Ruby Symbol by using
+
+  VALUE ID2SYM(ID id)
+
+and to convert Ruby Symbol object to ID, use
+
+  ID SYM2ID(VALUE symbol)
+
+==== Invoke Ruby Method from C
+
+To invoke methods directly, you can use the function below
+
+  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
+
+This function invokes a method on the recv, with the method name
+specified by the symbol mid.
+
+==== Accessing the Variables and Constants
+
+You can access class variables and instance variables using access
+functions.  Also, global variables can be shared between both
+environments.  There's no way to access Ruby's local variables.
+
+The functions to access/modify instance variables are below:
+
+  VALUE rb_ivar_get(VALUE obj, ID id)
+  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
+
+id must be the symbol, which can be retrieved by rb_intern().
+
+To access the constants of the class/module:
+
+  VALUE rb_const_get(VALUE obj, ID id)
+
+See also Constant Definition above.
+
+== Information Sharing Between Ruby and C
+
+=== Ruby Constants That Can Be Accessed From C
+
+As stated in section 1.3,
+the following Ruby constants can be referred from C.
+
+Qtrue ::
+Qfalse ::
+
+  Boolean values.  Qfalse is false in C also (i.e. 0).
+
+Qnil ::
+
+  Ruby nil in C scope.
+
+=== Global Variables Shared Between C and Ruby
+
+Information can be shared between the two environments using shared global
+variables.  To define them, you can use functions listed below:
+
+  void rb_define_variable(const char *name, VALUE *var)
+
+This function defines the variable which is shared by both environments.
+The value of the global variable pointed to by `var' can be accessed
+through Ruby's global variable named `name'.
+
+You can define read-only (from Ruby, of course) variables using the
+function below.
+
+  void rb_define_readonly_variable(const char *name, VALUE *var)
+
+You can define hooked variables.  The accessor functions (getter and
+setter) are called on access to the hooked variables.
+
+  void rb_define_hooked_variable(const char *name, VALUE *var,
+                                 VALUE (*getter)(), void (*setter)())
+
+If you need to supply either setter or getter, just supply 0 for the
+hook you don't need.  If both hooks are 0, rb_define_hooked_variable()
+works just like rb_define_variable().
+
+The prototypes of the getter and setter functions are as follows:
+
+  VALUE (*getter)(ID id, VALUE *var);
+  void (*setter)(VALUE val, ID id, VALUE *var);
+
+Also you can define a Ruby global variable without a corresponding C
+variable.  The value of the variable will be set/get only by hooks.
+
+  void rb_define_virtual_variable(const char *name,
+                                  VALUE (*getter)(), void (*setter)())
+
+The prototypes of the getter and setter functions are as follows:
+
+  VALUE (*getter)(ID id);
+  void (*setter)(VALUE val, ID id);
+
+=== Encapsulate C Data into a Ruby Object
+
+Sometimes you need to expose your struct in the C world as a Ruby
+object.
+In a situation like this, making use of the TypedData_XXX macro
+family, the pointer to the struct and the Ruby object can be mutually
+converted.
+
+--
+The old (non-Typed) Data_XXX macro family has been deprecated.
+In the future version of Ruby, it is possible old macros will not
+work.
+++
+
+==== C struct to Ruby object
+
+You can convert sval, a pointer to your struct, into a Ruby object
+with the next macro.
+
+  TypedData_Wrap_Struct(klass, data_type, sval)
+
+TypedData_Wrap_Struct() returns a created Ruby object as a VALUE.
+
+The klass argument is the class for the object.  The klass should
+derive from rb_cObject, and the allocator must be set by calling
+rb_define_alloc_func or rb_undef_alloc_func.
+
+data_type is a pointer to a const rb_data_type_t which describes
+how Ruby should manage the struct.
+
+rb_data_type_t is defined like this.  Let's take a look at each
+member of the struct.
+
+  typedef struct rb_data_type_struct rb_data_type_t;
+
+  struct rb_data_type_struct {
+      const char *wrap_struct_name;
+      struct {
+          void (*dmark)(void*);
+          void (*dfree)(void*);
+          size_t (*dsize)(const void *);
+          void (*dcompact)(void*);
+          void *reserved[1];
+      } function;
+      const rb_data_type_t *parent;
+      void *data;
+      VALUE flags;
+  };
+
+wrap_struct_name is an identifier of this instance of the struct.
+It is basically used for collecting and emitting statistics.
+So the identifier must be unique in the process, but doesn't need
+to be valid as a C or Ruby identifier.
+
+These dmark / dfree functions are invoked during GC execution.  No
+object allocations are allowed during it, so do not allocate ruby
+objects inside them.
+
+dmark is a function to mark Ruby objects referred from your struct.
+It must mark all references from your struct with rb_gc_mark or
+its family if your struct keeps such references.
+
+--
+Note that it is recommended to avoid such a reference.
+++
+
+dfree is a function to free the pointer allocation.
+If this is RUBY_DEFAULT_FREE, the pointer will be just freed.
+
+dsize calculates memory consumption in bytes by the struct.
+Its parameter is a pointer to your struct.
+You can pass 0 as dsize if it is hard to implement such a function.
+But it is still recommended to avoid 0.
+
+dcompact is invoked when memory compaction took place.
+Referred Ruby objects that were marked by rb_gc_mark_movable()
+can here be updated per rb_gc_location().
+
+You have to fill reserved with 0.
+
+parent can point to another C type definition that the Ruby object
+is inherited from. Then TypedData_Get_Struct() does also accept
+derived objects.
+
+You can fill "data" with an arbitrary value for your use.
+Ruby does nothing with the member.
+
+flags is a bitwise-OR of the following flag values.
+Since they require deep understanding of garbage collector in Ruby,
+you can just set 0 to flags if you are not sure.
+
+RUBY_TYPED_FREE_IMMEDIATELY ::
+
+  This flag makes the garbage collector immediately invoke dfree()
+  during GC when it need to free your struct.
+  You can specify this flag if the dfree never unlocks Ruby's
+  internal lock (GVL).
+
+  If this flag is not set, Ruby defers invocation of dfree()
+  and invokes dfree() at the same time as finalizers.
+
+RUBY_TYPED_WB_PROTECTED ::
+
+  It shows that implementation of the object supports write barriers.
+  If this flag is set, Ruby is better able to do garbage collection
+  of the object.
+
+  When it is set, however, you are responsible for putting write
+  barriers in all implementations of methods of that object as
+  appropriate. Otherwise Ruby might crash while running.
+
+  More about write barriers can be found in "Generational GC" in
+  Appendix D.
+
+RUBY_TYPED_FROZEN_SHAREABLE ::
+
+  This flag indicates that the object is shareable object
+  if the object is frozen. See Appendix F more details.
+
+  If this flag is not set, the object can not become a shareable
+  object by Ractor.make_shareable() method.
+
+You can allocate and wrap the structure in one step.
+
+  TypedData_Make_Struct(klass, type, data_type, sval)
+
+This macro returns an allocated Data object, wrapping the pointer to
+the structure, which is also allocated.  This macro works like:
+
+  (sval = ZALLOC(type), TypedData_Wrap_Struct(klass, data_type, sval))
+
+Arguments klass and data_type work like their counterparts in
+TypedData_Wrap_Struct().  A pointer to the allocated structure will
+be assigned to sval, which should be a pointer of the type specified.
+
+==== Ruby object to C struct
+
+To retrieve the C pointer from the Data object, use the macro
+TypedData_Get_Struct().
+
+  TypedData_Get_Struct(obj, type, &data_type, sval)
+
+A pointer to the structure will be assigned to the variable sval.
+
+See the example below for details.
+
+== Example - Creating the dbm Extension
+
+OK, here's the example of making an extension library.  This is the
+extension to access DBMs.  The full source is included in the ext/
+directory in the Ruby's source tree.
+
+=== Make the Directory
+
+  % mkdir ext/dbm
+
+Make a directory for the extension library under ext directory.
+
+=== Design the Library
+
+You need to design the library features, before making it.
+
+=== Write the C Code
+
+You need to write C code for your extension library.  If your library
+has only one source file, choosing ``LIBRARY.c'' as a file name is
+preferred.  On the other hand, in case your library has multiple source
+files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
+with an intermediate file ``LIBRARY.o'' on some platforms.
+Note that some functions in mkmf library described below generate
+a file ``conftest.c'' for checking with compilation.  You shouldn't
+choose ``conftest.c'' as a name of a source file.
+
+Ruby will execute the initializing function named ``Init_LIBRARY'' in
+the library.  For example, ``Init_dbm()'' will be executed when loading
+the library.
+
+Here's the example of an initializing function.
+
+  #include <ruby.h>
+  void
+  Init_dbm(void)
+  {
+      /* define DBM class */
+      VALUE cDBM = rb_define_class("DBM", rb_cObject);
+      /* Redefine DBM.allocate
+      rb_define_alloc_func(cDBM, fdbm_alloc);
+      /* DBM includes Enumerable module */
+      rb_include_module(cDBM, rb_mEnumerable);
+
+      /* DBM has class method open(): arguments are received as C array */
+      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
+
+      /* DBM instance method close(): no args */
+      rb_define_method(cDBM, "close", fdbm_close, 0);
+      /* DBM instance method []: 1 argument */
+      rb_define_method(cDBM, "[]", fdbm_aref, 1);
+
+      /* ... */
+
+      /* ID for a instance variable to store DBM data */
+      id_dbm = rb_intern("dbm");
+  }
+
+The dbm extension wraps the dbm struct in the C environment using
+TypedData_Make_Struct.
+
+  struct dbmdata {
+      int  di_size;
+      DBM *di_dbm;
+  };
+
+  static const rb_data_type_t dbm_type = {
+      "dbm",
+      {0, free_dbm, memsize_dbm,},
+      0, 0,
+      RUBY_TYPED_FREE_IMMEDIATELY,
+  };
+
+  static VALUE
+  fdbm_alloc(VALUE klass)
+  {
+      struct dbmdata *dbmp;
+      /* Allocate T_DATA object and C struct and fill struct with zero bytes */
+      return TypedData_Make_Struct(klass, struct dbmdata, &dbm_type, dbmp);
+  }
+
+This code wraps the dbmdata structure into a Ruby object.  We avoid
+wrapping DBM* directly, because we want to cache size information.
+Since Object.allocate allocates an ordinary T_OBJECT type (instead
+of T_DATA), it's important to either use rb_define_alloc_func() to
+overwrite it or rb_undef_alloc_func() to delete it.
+
+To retrieve the dbmdata structure from a Ruby object, we define the
+following macro:
+
+  #define GetDBM(obj, dbmp) do {\
+      TypedData_Get_Struct((obj), struct dbmdata, &dbm_type, (dbmp));\
+      if ((dbmp) == 0) closed_dbm();\
+      if ((dbmp)->di_dbm == 0) closed_dbm();\
+  } while (0)
+
+This sort of complicated macro does the retrieving and close checking
+for the DBM.
+
+There are three kinds of way to receive method arguments.  First,
+methods with a fixed number of arguments receive arguments like this:
+
+  static VALUE
+  fdbm_aref(VALUE obj, VALUE keystr)
+  {
+      struct dbmdata *dbmp;
+      GetDBM(obj, dbmp);
+      /* Use dbmp to access the key */
+      dbm_fetch(dbmp->di_dbm, StringValueCStr(keystr));
+      /* ... */
+  }
+
+The first argument of the C function is the self, the rest are the
+arguments to the method.
+
+Second, methods with an arbitrary number of arguments receive
+arguments like this:
+
+  static VALUE
+  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
+  {
+      /* ... */
+      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
+          mode = 0666;          /* default value */
+      }
+      /* ... */
+  }
+
+The first argument is the number of method arguments, the second
+argument is the C array of the method arguments, and the third
+argument is the receiver of the method.
+
+You can use the function rb_scan_args() to check and retrieve the
+arguments.  The third argument is a string that specifies how to
+capture method arguments and assign them to the following VALUE
+references.
+
+You can just check the argument number with rb_check_arity(), this is
+handy in the case you want to treat the arguments as a list.
+
+The following is an example of a method that takes arguments by Ruby's
+array:
+
+  static VALUE
+  thread_initialize(VALUE thread, VALUE args)
+  {
+      /* ... */
+  }
+
+The first argument is the receiver, the second one is the Ruby array
+which contains the arguments to the method.
+
+<b>Notice</b>: GC should know about global variables which refer to Ruby's objects,
+but are not exported to the Ruby world.  You need to protect them by
+
+  void rb_global_variable(VALUE *var)
+
+or the objects themselves by
+
+  void rb_gc_register_mark_object(VALUE object)
+
+=== Prepare extconf.rb
+
+If the file named extconf.rb exists, it will be executed to generate
+Makefile.
+
+extconf.rb is the file for checking compilation conditions etc.  You
+need to put
+
+  require 'mkmf'
+
+at the top of the file.  You can use the functions below to check
+various conditions.
+
+  append_cppflags(array-of-flags[, opt]): append each flag to $CPPFLAGS if usable
+  append_cflags(array-of-flags[, opt]): append each flag to $CFLAGS if usable
+  append_ldflags(array-of-flags[, opt]): append each flag to $LDFLAGS if usable
+  have_macro(macro[, headers[, opt]]): check whether macro is defined
+  have_library(lib[, func[, headers[, opt]]]): check whether library containing function exists
+  find_library(lib[, func, *paths]): find library from paths
+  have_func(func[, headers[, opt]): check whether function exists
+  have_var(var[, headers[, opt]]): check whether variable exists
+  have_header(header[, preheaders[, opt]]): check whether header file exists
+  find_header(header, *paths): find header from paths
+  have_framework(fw): check whether framework exists (for MacOS X)
+  have_struct_member(type, member[, headers[, opt]]): check whether struct has member
+  have_type(type[, headers[, opt]]): check whether type exists
+  find_type(type, opt, *headers): check whether type exists in headers
+  have_const(const[, headers[, opt]]): check whether constant is defined
+  check_sizeof(type[, headers[, opts]]): check size of type
+  check_signedness(type[, headers[, opts]]): check signedness of type
+  convertible_int(type[, headers[, opts]]): find convertible integer type
+  find_executable(bin[, path]): find executable file path
+  create_header(header): generate configured header
+  create_makefile(target[, target_prefix]): generate Makefile
+
+See MakeMakefile for full documentation of these functions.
+
+The value of the variables below will affect the Makefile.
+
+  $CFLAGS: included in CFLAGS make variable (such as -O)
+  $CPPFLAGS: included in CPPFLAGS make variable (such as -I, -D)
+  $LDFLAGS: included in LDFLAGS make variable (such as -L)
+  $objs: list of object file names
+
+Compiler/linker flags are not portable usually, you should use
++append_cppflags+, +append_cpflags+ and +append_ldflags+ respectively
+instead of appending the above variables directly.
+
+Normally, the object files list is automatically generated by searching
+source files, but you must define them explicitly if any sources will
+be generated while building.
+
+If a compilation condition is not fulfilled, you should not call
+``create_makefile''.  The Makefile will not be generated, compilation will
+not be done.
+
+=== Prepare Depend (Optional)
+
+If the file named depend exists, Makefile will include that file to
+check dependencies.  You can make this file by invoking
+
+  % gcc -MM *.c > depend
+
+It's harmless.  Prepare it.
+
+=== Generate Makefile
+
+Try generating the Makefile by:
+
+  ruby extconf.rb
+
+If the library should be installed under vendor_ruby directory
+instead of site_ruby directory, use --vendor option as follows.
+
+  ruby extconf.rb --vendor
+
+You don't need this step if you put the extension library under the ext
+directory of the ruby source tree.  In that case, compilation of the
+interpreter will do this step for you.
+
+=== Run make
+
+Type
+
+  make
+
+to compile your extension.  You don't need this step either if you have
+put the extension library under the ext directory of the ruby source tree.
+
+=== Debug
+
+You may need to rb_debug the extension.  Extensions can be linked
+statically by adding the directory name in the ext/Setup file so that
+you can inspect the extension with the debugger.
+
+=== Done! Now You Have the Extension Library
+
+You can do anything you want with your library.  The author of Ruby
+will not claim any restrictions on your code depending on the Ruby API.
+Feel free to use, modify, distribute or sell your program.

+
+=== Ruby Header Files
+
+Everything under <tt>$repo_root/include/ruby</tt> is installed with
+<tt>make install</tt>.
+It should be included per <tt>#include <ruby.h></tt> from C extensions.
+All symbols are public API with the exception of symbols prefixed with
++rbimpl_+ or +RBIMPL_+. They are implementation details and shouldn't
+be used by C extensions.
+
+Only <tt>$repo_root/include/ruby/*.h</tt> whose corresponding macros
+are defined in the <tt>$repo_root/include/ruby.h</tt> header are
+allowed to be <tt>#include</tt>-d by C extensions.
+
+Header files under <tt>$repo_root/internal/</tt> or directly under the
+root <tt>$repo_root/*.h</tt> are not make-installed.
+They are internal headers with only internal APIs.

+  function.
+
+Data_Make_Struct(klass, type, mark, free, sval) ::

+  This macro allocates memory using malloc(), assigns it to the variable
+  sval, and returns the DATA encapsulating the pointer to memory region.

+
+void rb_extend_object(VALUE object, VALUE module) ::
+
+  Extend the object with the module's attributes.
+
+=== Defining Global Variables
+
+void rb_define_variable(const char *name, VALUE *var) ::
+
+  Defines a global variable which is shared between C and Ruby.  If name
+  contains a character which is not allowed to be part of the symbol,
+  it can't be seen from Ruby programs.
+
+void rb_define_readonly_variable(const char *name, VALUE *var) ::
+
+  Defines a read-only global variable.  Works just like
+  rb_define_variable(), except the defined variable is read-only.
+
+void rb_define_virtual_variable(const char *name, VALUE (*getter)(), void (*setter)()) ::
+
+  Defines a virtual variable, whose behavior is defined by a pair of C
+  functions.  The getter function is called when the variable is

+
+  Defines a new constant under the class/module.
+
+void rb_define_global_const(const char *name, VALUE val) ::
+
+  Defines a global constant.  This is just the same as
+
+    rb_define_const(rb_cObject, name, val)
+
+=== Method Definition
+
+rb_define_method(VALUE klass, const char *name, VALUE (*func)(ANYARGS), int argc) ::
+
+  Defines a method for the class.  func is the function pointer.  argc
+  is the number of arguments.  if argc is -1, the function will receive
+  3 arguments: argc, argv, and self.  if argc is -2, the function will
+  receive 2 arguments, self and args, where args is a Ruby array of
+  the method arguments.
+
+rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(ANYARGS), int argc) ::
+
+  Defines a private method for the class.  Arguments are same as
+  rb_define_method().
+
+rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(ANYARGS), int argc) ::
+
+  Defines a singleton method.  Arguments are same as rb_define_method().
+
+rb_check_arity(int argc, int min, int max) ::
+
+  Check the number of arguments, argc is in the range of min..max.  If
+  max is UNLIMITED_ARGUMENTS, upper bound is not checked.  If argc is
+  out of bounds, an ArgumentError will be raised.
+
+rb_scan_args(int argc, VALUE *argv, const char *fmt, ...) ::
+
+  Retrieve argument from argc and argv to given VALUE references
+  according to the format string.  The format can be described in ABNF
+  as follows:
+
+    scan-arg-spec  := param-arg-spec [keyword-arg-spec] [block-arg-spec]
+
+    param-arg-spec := pre-arg-spec [post-arg-spec] / post-arg-spec /
+                      pre-opt-post-arg-spec
+    pre-arg-spec   := num-of-leading-mandatory-args [num-of-optional-args]
+    post-arg-spec  := sym-for-variable-length-args
+                      [num-of-trailing-mandatory-args]
+    pre-opt-post-arg-spec := num-of-leading-mandatory-args num-of-optional-args
+                             num-of-trailing-mandatory-args
+    keyword-arg-spec := sym-for-keyword-arg
+    block-arg-spec := sym-for-block-arg
+
+    num-of-leading-mandatory-args  := DIGIT ; The number of leading
+                                            ; mandatory arguments
+    num-of-optional-args           := DIGIT ; The number of optional
+                                            ; arguments
+    sym-for-variable-length-args   := "*"   ; Indicates that variable
+                                            ; length arguments are
+                                            ; captured as a ruby array
+    num-of-trailing-mandatory-args := DIGIT ; The number of trailing
+                                            ; mandatory arguments
+    sym-for-keyword-arg            := ":"   ; Indicates that keyword
+                                            ; argument captured as a hash.
+                                            ; If keyword arguments are not
+                                            ; provided, returns nil.
+    sym-for-block-arg              := "&"   ; Indicates that an iterator
+                                            ; block should be captured if
+                                            ; given
+
+  For example, "12" means that the method requires at least one
+  argument, and at most receives three (1+2) arguments.  So, the format
+  string must be followed by three variable references, which are to be
+  assigned to captured arguments.  For omitted arguments, variables are
+  set to Qnil.  NULL can be put in place of a variable reference, which
+  means the corresponding captured argument(s) should be just dropped.
+
+  The number of given arguments, excluding an option hash or iterator
+  block, is returned.
+
+rb_scan_args_kw(int kw_splat, int argc, VALUE *argv, const char *fmt, ...) ::
+
+  The same as +rb_scan_args+, except the +kw_splat+ argument specifies whether
+  keyword arguments are provided (instead of being determined by the call
+  from Ruby to the C function). +kw_splat+ should be one of the following
+  values:
+
+  RB_SCAN_ARGS_PASS_CALLED_KEYWORDS :: Same behavior as +rb_scan_args+.
+  RB_SCAN_ARGS_KEYWORDS :: The final argument should be a hash treated as
+                           keywords.
+  RB_SCAN_ARGS_LAST_HASH_KEYWORDS :: Treat a final argument as keywords if it
+                                     is a hash, and not as keywords otherwise.
+
+int rb_get_kwargs(VALUE keyword_hash, const ID *table, int required, int optional, VALUE *values) ::
+
+  Retrieves argument VALUEs bound to keywords, which directed by +table+
+  into +values+, deleting retrieved entries from +keyword_hash+ along
+  the way.  First +required+ number of IDs referred by +table+ are
+  mandatory, and succeeding +optional+ (- +optional+ - 1 if
+  +optional+ is negative) number of IDs are optional.  If a
+  mandatory key is not contained in +keyword_hash+, raises "missing
+  keyword" +ArgumentError+.  If an optional key is not present in
+  +keyword_hash+, the corresponding element in +values+ is set to +Qundef+.
+  If +optional+ is negative, rest of +keyword_hash+ are ignored, otherwise
+  raises "unknown keyword" +ArgumentError+.
+
+  Be warned, handling keyword arguments in the C API is less efficient
+  than handling them in Ruby.  Consider using a Ruby wrapper method
+  around a non-keyword C function.
+  ref: https://bugs.ruby-lang.org/issues/11339
+
+VALUE rb_extract_keywords(VALUE *original_hash) ::
+
+  Extracts pairs whose key is a symbol into a new hash from a hash
+  object referred by +original_hash+.  If the original hash contains
+  non-symbol keys, then they are copied to another hash and the new hash
+  is stored through +original_hash+, else 0 is stored.

+
+\[OBSOLETE] VALUE rb_iterate(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::

+  called with the argument arg1.  func2 receives the value from yield as
+  the first argument, arg2 as the second argument.
+
+  When rb_iterate is used in 1.9, func1 has to call some Ruby-level method.
+  This function is obsolete since 1.9; use rb_block_call instead.

+  of rb_rescue() is the return value from func1 if no exception occurs,
+  from func2 otherwise.
+
+VALUE rb_ensure(VALUE (*func1)(ANYARGS), VALUE arg1, VALUE (*func2)(ANYARGS), VALUE arg2) ::
+

+  with arg2 if execution terminated.  The return value from
+  rb_ensure() is that of func1 when no exception occurred.
+
+VALUE rb_protect(VALUE (*func) (VALUE), VALUE arg, int *state) ::
+
+  Calls the function func with arg as the argument.  If no exception
+  occurred during func, it returns the result of func and *state is zero.
+  Otherwise, it returns Qnil and sets *state to nonzero.  If state is
+  NULL, it is not set in both cases.
+  You have to clear the error info with rb_set_errinfo(Qnil) when
+  ignoring the caught exception.
+
+void rb_jump_tag(int state) ::
+
+  Continues the exception caught by rb_protect() and rb_eval_string_protect().
+  state must be the returned value from those functions.  This function
+  never return to the caller.
+
+void rb_iter_break() ::
+
+  Exits from the current innermost block.  This function never return to
+  the caller.
+
+void rb_iter_break_value(VALUE value) ::
+
+  Exits from the current innermost block with the value.  The block will
+  return the given argument value.  This function never return to the
+  caller.
+
+=== Exceptions and Errors
+
+void rb_warn(const char *fmt, ...) ::
+
+  Prints a warning message according to a printf-like format.
+
+void rb_warning(const char *fmt, ...) ::
+
+  Prints a warning message according to a printf-like format, if
+  $VERBOSE is true.
+
+void rb_raise(rb_eRuntimeError, const char *fmt, ...) ::
+
+  Raises RuntimeError.  The fmt is a format string just like printf().
+
+void rb_raise(VALUE exception, const char *fmt, ...) ::
+
+  Raises a class exception.  The fmt is a format string just like printf().
+
+void rb_fatal(const char *fmt, ...) ::
+
+  Raises a fatal error, terminates the interpreter.  No exception handling
+  will be done for fatal errors, but ensure blocks will be executed.
+
+void rb_bug(const char *fmt, ...) ::
+
+  Terminates the interpreter immediately.  This function should be
+  called under the situation caused by the bug in the interpreter.  No
+  exception handling nor ensure execution will be done.
+
+Note: In the format string, "%"PRIsVALUE can be used for Object#to_s
+(or Object#inspect if '+' flag is set) output (and related argument
+must be a VALUE).  Since it conflicts with "%i", for integers in
+format strings, use "%d".
+
+=== Threading
+
+As of Ruby 1.9, Ruby supports native 1:1 threading with one kernel
+thread per Ruby Thread object.  Currently, there is a GVL (Global VM Lock)
+which prevents simultaneous execution of Ruby code which may be released
+by the rb_thread_call_without_gvl and rb_thread_call_without_gvl2 functions.
+These functions are tricky-to-use and documented in thread.c; do not
+use them before reading comments in thread.c.
+
+void rb_thread_schedule(void) ::
+
+  Give the scheduler a hint to pass execution to another thread.
+
+=== Input/Output (IO) on a single file descriptor
+
+int rb_io_wait_readable(int fd) ::
+
+  Wait indefinitely for the given FD to become readable, allowing other
+  threads to be scheduled.  Returns a true value if a read may be
+  performed, false if there is an unrecoverable error.
+
+int rb_io_wait_writable(int fd) ::
+
+  Like rb_io_wait_readable, but for writability.
+
+int rb_wait_for_single_fd(int fd, int events, struct timeval *timeout) ::
+
+  Allows waiting on a single FD for one or multiple events with a
+  specified timeout.
+
+  +events+ is a mask of any combination of the following values:
+
+  * RB_WAITFD_IN - wait for readability of normal data
+  * RB_WAITFD_OUT - wait for writability
+  * RB_WAITFD_PRI - wait for readability of urgent data
+
+  Use a NULL +timeout+ to wait indefinitely.
+
+=== I/O Multiplexing
+
+Ruby supports I/O multiplexing based on the select(2) system call.
+The Linux select_tut(2) manpage
+<http://man7.org/linux/man-pages/man2/select_tut.2.html>
+provides a good overview on how to use select(2), and the Ruby API has
+analogous functions and data structures to the well-known select API.
+Understanding of select(2) is required to understand this section.
+
+typedef struct rb_fdset_t ::
+
+  The data structure which wraps the fd_set bitmap used by select(2).
+  This allows Ruby to use FD sets larger than that allowed by
+  historic limitations on modern platforms.
+
+void rb_fd_init(rb_fdset_t *) ::
+
+  Initializes the rb_fdset_t, it must be initialized before other rb_fd_*
+  operations.  Analogous to calling malloc(3) to allocate an fd_set.
+
+void rb_fd_term(rb_fdset_t *) ::
+
+  Destroys the rb_fdset_t, releasing any memory and resources it used.
+  It must be reinitialized using rb_fd_init before future use.
+  Analogous to calling free(3) to release memory for an fd_set.
+
+void rb_fd_zero(rb_fdset_t *) ::
+
+  Clears all FDs from the rb_fdset_t, analogous to FD_ZERO(3).
+
+void rb_fd_set(int fd, rb_fdset_t *) ::
+
+  Adds a given FD in the rb_fdset_t, analogous to FD_SET(3).
+
+void rb_fd_clr(int fd, rb_fdset_t *) ::
+
+  Removes a given FD from the rb_fdset_t, analogous to FD_CLR(3).
+
+int rb_fd_isset(int fd, const rb_fdset_t *) ::
+
+  Returns true if a given FD is set in the rb_fdset_t, false if not.
+  Analogous to FD_ISSET(3).
+
+int rb_thread_fd_select(int nfds, rb_fdset_t *readfds, rb_fdset_t *writefds, rb_fdset_t *exceptfds, struct timeval *timeout) ::
+
+  Analogous to the select(2) system call, but allows other Ruby
+  threads to be scheduled while waiting.
+
+  When only waiting on a single FD, favor rb_io_wait_readable,
+  rb_io_wait_writable, or rb_wait_for_single_fd functions since
+  they can be optimized for specific platforms (currently, only Linux).
+
+=== Initialize and Start the Interpreter
+
+The embedding API functions are below (not needed for extension libraries):
+
+void ruby_init() ::
+
+  Initializes the interpreter.
+
+void *ruby_options(int argc, char **argv) ::
+
+  Process command line arguments for the interpreter.
+  And compiles the Ruby source to execute.
+  It returns an opaque pointer to the compiled source
+  or an internal special value.
+
+int ruby_run_node(void *n) ::
+
+  Runs the given compiled source and exits this process.
+  It returns EXIT_SUCCESS if successfully runs the source.
+  Otherwise, it returns other value.
+
+void ruby_script(char *name) ::
+
+  Specifies the name of the script ($0).
+
+=== Hooks for the Interpreter Events
+
+void rb_add_event_hook(rb_event_hook_func_t func, rb_event_flag_t events, VALUE data) ::
+
+  Adds a hook function for the specified interpreter events.
+  events should be OR'ed value of:
+
+    RUBY_EVENT_LINE
+    RUBY_EVENT_CLASS
+    RUBY_EVENT_END
+    RUBY_EVENT_CALL
+    RUBY_EVENT_RETURN
+    RUBY_EVENT_C_CALL
+    RUBY_EVENT_C_RETURN
+    RUBY_EVENT_RAISE
+    RUBY_EVENT_ALL
+
+  The definition of rb_event_hook_func_t is below:
+
+    typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
+                                         VALUE self, ID id, VALUE klass)
+
+  The third argument `data' to rb_add_event_hook() is passed to the hook
+  function as the second argument, which was the pointer to the current
+  NODE in 1.8.  See RB_EVENT_HOOKS_HAVE_CALLBACK_DATA below.
+
+int rb_remove_event_hook(rb_event_hook_func_t func) ::
+
+  Removes the specified hook function.
+
+=== Memory usage
+
+void rb_gc_adjust_memory_usage(ssize_t diff) ::
+
+  Adjusts the amount of registered external memory.  You can tell GC how
+  much memory is used by an external library by this function.  Calling
+  this function with positive diff means the memory usage is increased;
+  new memory block is allocated or a block is reallocated as larger
+  size.  Calling this function with negative diff means the memory usage
+  is decreased; a memory block is freed or a block is reallocated as
+  smaller size.  This function may trigger the GC.
+
+=== Macros for Compatibility
+
+Some macros to check API compatibilities are available by default.
+
+NORETURN_STYLE_NEW ::
+
+  Means that NORETURN macro is functional style instead of prefix.
+
+HAVE_RB_DEFINE_ALLOC_FUNC ::
+
+  Means that function rb_define_alloc_func() is provided, that means the
+  allocation framework is used.  This is the same as the result of
+  have_func("rb_define_alloc_func", "ruby.h").
+
+HAVE_RB_REG_NEW_STR ::
+
+  Means that function rb_reg_new_str() is provided, that creates Regexp
+  object from String object.  This is the same as the result of
+  have_func("rb_reg_new_str", "ruby.h").
+
+HAVE_RB_IO_T ::
+
+  Means that type rb_io_t is provided.
+
+USE_SYMBOL_AS_METHOD_NAME ::
+
+  Means that Symbols will be returned as method names, e.g.,
+  Module#methods, \#singleton_methods and so on.
+
+HAVE_RUBY_*_H ::
+
+  Defined in ruby.h and means corresponding header is available.  For
+  instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
+  mere st.h.
+
+  Header files corresponding to these macros may be <tt>#include</tt>
+  directly from extension libraries.
+
+RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
+
+  Means that rb_add_event_hook() takes the third argument `data', to be
+  passed to the given event hook function.
+
+=== Defining backward compatible macros for keyword argument functions
+
+Most ruby C extensions are designed to support multiple Ruby versions.
+In order to correctly support Ruby 2.7+ in regards to keyword
+argument separation, C extensions need to use <code>*_kw</code>
+functions.  However, these functions do not exist in Ruby 2.6 and
+below, so in those cases macros should be defined to allow you to use
+the same code on multiple Ruby versions.  Here are example macros
+you can use in extensions that support Ruby 2.6 (or below) when using
+the <code>*_kw</code> functions introduced in Ruby 2.7.
+

+  #define RETURN_SIZED_ENUMERATOR_KW(obj, argc, argv, size_fn, kw_splat) do { \
+          if (!rb_block_given_p())                                            \
+              return SIZED_ENUMERATOR(obj, argc, argv, size_fn);              \

+
+See documentation for {mkmf}[rdoc-ref:MakeMakefile].
+
+== Appendix D. Generational GC
+
+Ruby 2.1 introduced a generational garbage collector (called RGenGC).
+RGenGC (mostly) keeps compatibility.
+
+Generally, the use of the technique called write barriers is required in
+extension libraries for generational GC
+(https://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29).
+RGenGC works fine without write barriers in extension libraries.
+
+If your library adheres to the following tips, performance can
+be further improved. Especially, the "Don't touch pointers directly" section is
+important.
+
+=== Incompatibility
+
+You can't write RBASIC(obj)->klass field directly because it is const
+value now.
+
+Basically you should not write this field because MRI expects it to be
+an immutable field, but if you want to do it in your extension you can
+use the following functions:
+
+VALUE rb_obj_hide(VALUE obj) ::
+
+  Clear RBasic::klass field. The object will be an internal object.
+  ObjectSpace::each_object can't find this object.
+
+VALUE rb_obj_reveal(VALUE obj, VALUE klass) ::
+
+  Reset RBasic::klass to be klass.
+  We expect the `klass' is hidden class by rb_obj_hide().
+
+=== Write barriers
+
+RGenGC doesn't require write barriers to support generational GC.
+However, caring about write barrier can improve the performance of
+RGenGC. Please check the following tips.
+
+==== Don't touch pointers directly
+
+In MRI (include/ruby/ruby.h), some macros to acquire pointers to the
+internal data structures are supported such as RARRAY_PTR(),
+RSTRUCT_PTR() and so on.
+
+DO NOT USE THESE MACROS and instead use the corresponding C-APIs such as
+rb_ary_aref(), rb_ary_store() and so on.
+
+==== Consider whether to insert write barriers
+
+You don't need to care about write barriers if you only use built-in
+types.
+
+If you support T_DATA objects, you may consider using write barriers.
+
+Inserting write barriers into T_DATA objects only works with the
+following type objects: (a) long-lived objects, (b) when a huge number
+of objects are generated and \(c) container-type objects that have
+references to other objects. If your extension provides such a type of
+T_DATA objects, consider inserting write barriers.
+
+(a): short-lived objects don't become old generation objects.
+(b): only a few oldgen objects don't have performance impact.
+\(c): only a few references don't have performance impact.
+
+Inserting write barriers is a very difficult hack, it is easy to
+introduce critical bugs. And inserting write barriers has several areas
+of overhead. Basically we don't recommend you insert write barriers.
+Please carefully consider the risks.
+
+==== Combine with built-in types
+
+Please consider utilizing built-in types. Most built-in types support
+write barrier, so you can use them to avoid manually inserting write
+barriers.
+
+For example, if your T_DATA has references to other objects, then you
+can move these references to Array. A T_DATA object only has a reference
+to an array object. Or you can also use a Struct object to gather a
+T_DATA object (without any references) and an that Array contains
+references.
+
+With use of such techniques, you don't need to insert write barriers
+anymore.
+
+==== Insert write barriers
+
+\[AGAIN] Inserting write barriers is a very difficult hack, and it is
+easy to introduce critical bugs. And inserting write barriers has
+several areas of overhead. Basically we don't recommend you insert write
+barriers. Please carefully consider the risks.
+
+Before inserting write barriers, you need to know about RGenGC algorithm
+(gc.c will help you). Macros and functions to insert write barriers are
+available in include/ruby/ruby.h. An example is available in iseq.c.
+
+For a complete guide for RGenGC and write barriers, please refer to
+<https://bugs.ruby-lang.org/projects/ruby-master/wiki/RGenGC>.
+
+== Appendix E. RB_GC_GUARD to protect from premature GC
+
+C Ruby currently uses conservative garbage collection, thus VALUE
+variables must remain visible on the stack or registers to ensure any
+associated data remains usable.  Optimizing C compilers are not designed
+with conservative garbage collection in mind, so they may optimize away
+the original VALUE even if the code depends on data associated with that
+VALUE.
+
+The following example illustrates the use of RB_GC_GUARD to ensure
+the contents of sptr remain valid while the second invocation of
+rb_str_new_cstr is running.
+
+  VALUE s, w;
+  const char *sptr;
+
+  s = rb_str_new_cstr("hello world!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
+  sptr = RSTRING_PTR(s);
+  w = rb_str_new_cstr(sptr + 6); /* Possible GC invocation */
+
+  RB_GC_GUARD(s); /* ensure s (and thus sptr) do not get GC-ed */
+
+In the above example, RB_GC_GUARD must be placed _after_ the last use of
+sptr.  Placing RB_GC_GUARD before dereferencing sptr would be of no use.
+RB_GC_GUARD is only effective on the VALUE data type, not converted C
+data types.
+
+RB_GC_GUARD would not be necessary at all in the above example if
+non-inlined function calls are made on the `s' VALUE after sptr is
+dereferenced.  Thus, in the above example, calling any un-inlined
+function on `s' such as:
+
+  rb_str_modify(s);
+
+Will ensure `s' stays on the stack or register to prevent a
+GC invocation from prematurely freeing it.
+
+Using the RB_GC_GUARD macro is preferable to using the "volatile"
+keyword in C.  RB_GC_GUARD has the following advantages:
+
+1. the intent of the macro use is clear
+
+2. RB_GC_GUARD only affects its call site, "volatile" generates some
+   extra code every time the variable is used, hurting optimization.
+
+3. "volatile" implementations may be buggy/inconsistent in some
+   compilers and architectures. RB_GC_GUARD is customizable for broken
+   systems/compilers without negatively affecting other systems.
+
+== Appendix F. Ractor support
+
+Ractor(s) are the parallel execution mechanism introduced in Ruby 3.0. All
+ractors can run in parallel on a different OS thread (using an underlying system
+provided thread), so the C extension should be thread-safe. A C extension that
+can run in multiple ractors is called "Ractor-safe".
+
+Ractor safety around C extensions has the following properties:
+1. By default, all C extensions are recognized as Ractor-unsafe.
+2. Ractor-unsafe C-methods may only be called from the main Ractor.  If invoked
+   by a non-main Ractor, then a Ractor::UnsafeError is raised.
+3. If an extension desires to be marked as Ractor-safe the extension should
+   call rb_ext_ractor_safe(true) at the Init_ function for the extension, and
+   all defined methods will be marked as Ractor-safe.
+
+To make a "Ractor-safe" C extension, we need to check the following points:
+
+(1) Do not share unshareable objects between ractors
+
+For example, C's global variable can lead sharing an unshareable objects
+between ractors.
+
+  VALUE g_var;
+  VALUE set(VALUE self, VALUE v){ return g_var = v; }
+  VALUE get(VALUE self){ return g_var; }
+
+set() and get() pair can share an unshareable objects using g_var, and
+it is Ractor-unsafe.
+
+Not only using global variables directly, some indirect data structure
+such as global st_table can share the objects, so please take care.
+
+Note that class and module objects are shareable objects, so you can
+keep the code "cFoo = rb_define_class(...)" with C's global variables.
+
+(2) Check the thread-safety of the extension
+
+An extension should be thread-safe. For example, the following code is
+not thread-safe:
+
+  bool g_called = false;
+  VALUE call(VALUE self) {
+    if (g_called) rb_raise("recursive call is not allowed.");
+    g_called = true;
+    VALUE ret = do_something();
+    g_called = false;
+    return ret;
+  }
+
+because g_called global variable should be synchronized by other
+ractor's threads. To avoid such data-race, some synchronization should
+be used. Check include/ruby/thread_native.h and include/ruby/atomic.h.
+
+With Ractors, all objects given as method parameters and the receiver (self)
+are guaranteed to be from the current Ractor or to be shareable. As a
+consequence, it is easier to make code ractor-safe than to make code generally
+thread-safe. For example, we don't need to lock an array object to access the
+element of it.
+
+(3) Check the thread-safety of any used library
+
+If the extension relies on an external library, such as a function foo() from
+a library libfoo, the function libfoo foo() should be thread safe.
+
+(4) Make an object shareable
+
+This is not required to make an extension Ractor-safe.
+
+If an extension provides special objects defined by rb_data_type_t,
+consider these objects can become shareable or not.
+
+RUBY_TYPED_FROZEN_SHAREABLE flag indicates that these objects can be
+shareable objects if the object is frozen. This means that if the object
+is frozen, the mutation of wrapped data is not allowed.
+
+(5) Others
+
+There are possibly other points or requirements which must be considered in the
+making of a Ractor-safe extension.  This document will be extended as they are
+discovered.

+# Fiber
+
+Fibers provide a mechanism for cooperative concurrency.
+
+## Context Switching
+
+Fibers execute a user-provided block. During the execution, the block may call `Fiber.yield` or `Fiber.transfer` to switch to another fiber. `Fiber#resume` is used to continue execution from the point where `Fiber.yield` was called.
+
+``` ruby
+#!/usr/bin/env ruby
+
+puts "1: Start program."
+
+f = Fiber.new do
+  puts "3: Entered fiber."
+  Fiber.yield
+  puts "5: Resumed fiber."
+end
+
+puts "2: Resume fiber first time."
+f.resume
+
+puts "4: Resume fiber second time."
+f.resume
+
+puts "6: Finished."
+```
+
+This program demonstrates the flow control of fibers.
+
+## Scheduler
+
+The scheduler interface is used to intercept blocking operations. A typical
+implementation would be a wrapper for a gem like `EventMachine` or `Async`. This
+design provides separation of concerns between the event loop implementation
+and application code. It also allows for layered schedulers which can perform
+instrumentation.
+
+To set the scheduler for the current thread:
+
+``` ruby
+Fiber.set_scheduler(MyScheduler.new)
+```
+
+When the thread exits, there is an implicit call to `set_scheduler`:
+
+``` ruby
+Fiber.set_scheduler(nil)
+```
+
+### Design
+
+The scheduler interface is designed to be a un-opinionated light-weight layer
+between user code and blocking operations. The scheduler hooks should avoid
+translating or converting arguments or return values. Ideally, the exact same
+arguments from the user code are provided directly to the scheduler hook with
+no changes.
+
+### Interface
+
+This is the interface you need to implement.
+
+``` ruby
+class Scheduler
+  # Wait for the specified process ID to exit.
+  # This hook is optional.
+  # @parameter pid [Integer] The process ID to wait for.
+  # @parameter flags [Integer] A bit-mask of flags suitable for `Process::Status.wait`.
+  # @returns [Process::Status] A process status instance.
+  def process_wait(pid, flags)
+    Thread.new do
+      Process::Status.wait(pid, flags)
+    end.value
+  end
+
+  # Wait for the given io readiness to match the specified events within
+  # the specified timeout.
+  # @parameter event [Integer] A bit mask of `IO::READABLE`,
+  #   `IO::WRITABLE` and `IO::PRIORITY`.
+  # @parameter timeout [Numeric] The amount of time to wait for the event in seconds.
+  # @returns [Integer] The subset of events that are ready.
+  def io_wait(io, events, timeout)
+  end
+
+  # Read from the given io into the specified buffer.
+  # WARNING: Experimental hook! Do not use in production code!
+  # @parameter io [IO] The io to read from.
+  # @parameter buffer [IO::Buffer] The buffer to read into.
+  # @parameter length [Integer] The minimum amount to read.

+```
+
+Additional hooks may be introduced in the future, we will use feature detection
+in order to enable these hooks.
+
+### Non-blocking Execution
+
+The scheduler hooks will only be used in special non-blocking execution
+contexts. Non-blocking execution contexts introduce non-determinism because the
+execution of scheduler hooks may introduce context switching points into your
+program.
+
+#### Fibers
+
+Fibers can be used to create non-blocking execution contexts.
+
+``` ruby
+Fiber.new do
+  puts Fiber.current.blocking? # false
+
+  # May invoke `Fiber.scheduler&.io_wait`.
+  io.read(...)
+
+  # May invoke `Fiber.scheduler&.io_wait`.
+  io.write(...)
+
+  # Will invoke `Fiber.scheduler&.kernel_sleep`.
+  sleep(n)
+end.resume
+```
+
+We also introduce a new method which simplifies the creation of these
+non-blocking fibers:
+
+``` ruby
+Fiber.schedule do
+  puts Fiber.current.blocking? # false
+end
+```
+
+The purpose of this method is to allow the scheduler to internally decide the
+policy for when to start the fiber, and whether to use symmetric or asymmetric
+fibers.
+
+You can also create blocking execution contexts:
+
+``` ruby
+Fiber.new(blocking: true) do
+  # Won't use the scheduler:
+  sleep(n)
+end
+```
+
+However you should generally avoid this unless you are implementing a scheduler.
+
+#### IO
+
+By default, I/O is non-blocking. Not all operating systems support non-blocking
+I/O. Windows is a notable example where socket I/O can be non-blocking but pipe
+I/O is blocking. Provided that there *is* a scheduler and the current thread *is
+non-blocking*, the operation will invoke the scheduler.
+
+#### Mutex
+
+The `Mutex` class can be used in a non-blocking context and is fiber specific.
+
+#### ConditionVariable
+
+The `ConditionVariable` class can be used in a non-blocking context and is
+fiber-specific.
+
+#### Queue / SizedQueue
+
+The `Queue` and `SizedQueue` classes can be used in a non-blocking context and
+are fiber-specific.
+
+#### Thread
+
+The `Thread#join` operation can be used in a non-blocking context and is
+fiber-specific.

+== Format Specifications
+
+Several Ruby core classes have instance method +printf+ or +sprintf+:
+
+- ARGF#printf
+- IO#printf
+- Kernel#printf
+- Kernel#sprintf
+
+Each of these methods takes:
+
+- Argument +format_string+, which has zero or more
+  embedded _format_ _specifications_ (see below).
+- Arguments <tt>*arguments</tt>, which are zero or more objects to be formatted.
+
+Each of these methods prints or returns the string
+resulting from replacing each
+format specification embedded in +format_string+ with a string form
+of the corresponding argument among +arguments+.
+
+A simple example:
+
+  sprintf('Name: %s; value: %d', 'Foo', 0) # => "Name: Foo; value: 0"
+
+A format specification has the form:
+
+  %[flags][width][.precision]type
+
+It consists of:
+
+- A leading percent character.
+- Zero or more _flags_ (each is a character).
+- An optional _width_ _specifier_ (an integer).
+- An optional _precision_ _specifier_ (a period followed by a non-negative integer).
+- A _type_ _specifier_ (a character).
+
+Except for the leading percent character,
+the only required part is the type specifier, so we begin with that.
+
+=== Type Specifiers
+
+This section provides a brief explanation of each type specifier.
+The links lead to the details and examples.
+
+==== \Integer Type Specifiers
+
+- +b+ or +B+: Format +argument+ as a binary integer.
+  See {Specifiers b and B}[rdoc-ref:format_specifications.rdoc@Specifiers+b+and+B].
+- +d+, +i+, or +u+ (all are identical):
+  Format +argument+ as a decimal integer.
+  See {Specifier d}[rdoc-ref:format_specifications.rdoc@Specifier+d].
+- +o+: Format +argument+ as an octal integer.
+  See {Specifier o}[rdoc-ref:format_specifications.rdoc@Specifier+o].
+- +x+ or +X+: Format +argument+ as a hexadecimal integer.
+  See {Specifiers x and X}[rdoc-ref:format_specifications.rdoc@Specifiers+x+and+X].
+
+==== Floating-Point Type Specifiers
+
+- +a+ or +A+: Format +argument+ as hexadecimal floating-point number.
+  See {Specifiers a and A}[rdoc-ref:format_specifications.rdoc@Specifiers+a+and+A].
+- +e+ or +E+: Format +argument+ in scientific notation.
+  See {Specifiers e and E}[rdoc-ref:format_specifications.rdoc@Specifiers+e+and+E].
+- +f+: Format +argument+ as a decimal floating-point number.
+  See {Specifier f}[rdoc-ref:format_specifications.rdoc@Specifier+f].
+- +g+ or +G+: Format +argument+ in a "general" format.
+  See {Specifiers g and G}[rdoc-ref:format_specifications.rdoc@Specifiers+g+and+G].
+
+==== Other Type Specifiers
+
+- +c+: Format +argument+ as a character.
+  See {Specifier c}[rdoc-ref:format_specifications.rdoc@Specifier+c].
+- +p+: Format +argument+ as a string via <tt>argument.inspect</tt>.
+  See {Specifier p}[rdoc-ref:format_specifications.rdoc@Specifier+p].
+- +s+: Format +argument+ as a string via <tt>argument.to_s</tt>.
+  See {Specifier s}[rdoc-ref:format_specifications.rdoc@Specifier+s].
+- <tt>%</tt>: Format +argument+ (<tt>'%'</tt>) as a single percent character.
+  See {Specifier %}[rdoc-ref:format_specifications.rdoc@Specifier+-25].
+
+=== Flags
+
+The effect of a flag may vary greatly among type specifiers.
+These remarks are general in nature.
+See {type-specific details}[rdoc-ref:format_specifications.rdoc@Type+Specifier+Details+and+Examples].
+
+Multiple flags may be given with single type specifier;
+order does not matter.
+
+==== <tt>' '</tt> Flag
+
+Insert a space before a non-negative number:
+
+  sprintf('%d', 10)  # => "10"
+  sprintf('% d', 10) # => " 10"
+
+Insert a minus sign for negative value:
+
+  sprintf('%d', -10)  # => "-10"
+  sprintf('% d', -10) # => "-10"
+
+==== <tt>'#'</tt> Flag
+
+Use an alternate format; varies among types:
+
+  sprintf('%x', 100)  # => "64"
+  sprintf('%#x', 100) # => "0x64"
+
+==== <tt>'+'</tt> Flag
+
+Add a leading plus sign for a non-negative number:
+
+  sprintf('%x', 100)  # => "64"
+  sprintf('%+x', 100) # => "+64"
+
+==== <tt>'-'</tt> Flag
+
+Left justify the value in its field:
+
+  sprintf('%6d', 100)  # => "   100"
+  sprintf('%-6d', 100) # => "100   "
+
+==== <tt>'0'</tt> Flag
+
+Left-pad with zeros instead of spaces:
+
+  sprintf('%6d', 100)  # => "   100"
+  sprintf('%06d', 100) # => "000100"
+
+==== <tt>'*'</tt> Flag
+
+Use the next argument as the field width:
+
+  sprintf('%d', 20, 14)  # => "20"
+  sprintf('%*d', 20, 14) # => "                  14"
+
+==== <tt>'n$'</tt> Flag
+
+Format the (1-based) <tt>n</tt>th argument into this field:
+
+    sprintf("%s %s", 'world', 'hello')     # => "world hello"
+    sprintf("%2$s %1$s", 'world', 'hello') # => "hello world"
+
+=== Width Specifier
+
+In general, a width specifier determines the minimum width (in characters)
+of the formatted field:
+
+  sprintf('%10d', 100)  # => "       100"
+
+  # Left-justify if negative.
+  sprintf('%-10d', 100) # => "100       "
+
+  # Ignore if too small.
+  sprintf('%1d', 100)   # => "100"
+
+=== Precision Specifier
+
+A precision specifier is a decimal point followed by zero or more
+decimal digits.
+
+For integer type specifiers, the precision specifies the minimum number of
+digits to be written. If the precision is shorter than the integer, the result is
+padded with leading zeros. There is no modification or truncation of the result
+if the integer is longer than the precision:
+
+  sprintf('%.3d', 1)    # => "001"
+  sprintf('%.3d', 1000) # => "1000"
+
+  # If the precision is 0 and the value is 0, nothing is written
+  sprintf('%.d', 0)  # => ""
+  sprintf('%.0d', 0) # => ""
+
+For the +a+/+A+, +e+/+E+, +f+/+F+ specifiers, the precision specifies
+the number of digits after the decimal point to be written:
+
+  sprintf('%.2f', 3.14159)  # => "3.14"
+  sprintf('%.10f', 3.14159) # => "3.1415900000"
+
+  # With no precision specifier, defaults to 6-digit precision.
+  sprintf('%f', 3.14159)    # => "3.141590"
+
+For the +g+/+G+ specifiers, the precision specifies
+the number of significant digits to be written:
+
+  sprintf('%.2g', 123.45)  # => "1.2e+02"
+  sprintf('%.3g', 123.45)  # => "123"
+  sprintf('%.10g', 123.45) # =>  "123.45"
+
+  # With no precision specifier, defaults to 6 significant digits.
+  sprintf('%g', 123.456789) # => "123.457"
+
+For the +s+, +p+ specifiers, the precision specifies
+the number of characters to write:
+
+  sprintf('%s', Time.now)    # => "2022-05-04 11:59:16 -0400"
+  sprintf('%.10s', Time.now) # => "2022-05-04"
+
+=== Type Specifier Details and Examples
+
+==== Specifiers +a+ and +A+
+
+Format +argument+ as hexadecimal floating-point number:
+
+  sprintf('%a', 3.14159)   # => "0x1.921f9f01b866ep+1"
+  sprintf('%a', -3.14159)  # => "-0x1.921f9f01b866ep+1"
+  sprintf('%a', 4096)      # => "0x1p+12"
+  sprintf('%a', -4096)     # => "-0x1p+12"
+
+  # Capital 'A' means that alphabetical characters are printed in upper case.
+  sprintf('%A', 4096)      # => "0X1P+12"
+  sprintf('%A', -4096)     # => "-0X1P+12"
+
+==== Specifiers +b+ and +B+
+
+The two specifiers +b+ and +B+ behave identically
+except when flag <tt>'#'</tt>+ is used.
+
+Format +argument+ as a binary integer:
+
+  sprintf('%b', 1)  # => "1"
+  sprintf('%b', 4)  # => "100"
+
+  # Prefix '..' for negative value.
+  sprintf('%b', -4) # => "..100"
+
+  # Alternate format.
+  sprintf('%#b', 4)  # => "0b100"
+  sprintf('%#B', 4)  # => "0B100"
+
+==== Specifier +c+
+
+Format +argument+ as a single character:
+
+  sprintf('%c', 'A') # => "A"
+  sprintf('%c', 65)  # => "A"
+
+==== Specifier +d+
+
+Format +argument+ as a decimal integer:
+
+  sprintf('%d', 100)  # => "100"
+  sprintf('%d', -100) # => "-100"
+
+Flag <tt>'#'</tt> does not apply.
+
+==== Specifiers +e+ and +E+
+
+Format +argument+ in
+{scientific notation}[https://en.wikipedia.org/wiki/Scientific_notation]:
+
+  sprintf('%e', 3.14159)  # => "3.141590e+00"
+  sprintf('%E', -3.14159) # => "-3.141590E+00"
+
+==== Specifier +f+
+
+Format +argument+ as a floating-point number:
+
+  sprintf('%f', 3.14159)  # => "3.141590"
+  sprintf('%f', -3.14159) # => "-3.141590"
+
+Flag <tt>'#'</tt> does not apply.
+
+==== Specifiers +g+ and +G+
+
+Format +argument+ using exponential form (+e+/+E+ specifier)
+if the exponent is less than -4 or greater than or equal to the precision.
+Otherwise format +argument+ using floating-point form (+f+ specifier):
+
+  sprintf('%g', 100)  # => "100"
+  sprintf('%g', 100.0)  # => "100"
+  sprintf('%g', 3.14159)  # => "3.14159"
+  sprintf('%g', 100000000000)  # => "1e+11"
+  sprintf('%g', 0.000000000001)  # => "1e-12"
+
+  # Capital 'G' means use capital 'E'.
+  sprintf('%G', 100000000000)  # => "1E+11"
+  sprintf('%G', 0.000000000001)  # => "1E-12"
+
+  # Alternate format.
+  sprintf('%#g', 100000000000)  # => "1.00000e+11"
+  sprintf('%#g', 0.000000000001)  # => "1.00000e-12"
+  sprintf('%#G', 100000000000)  # => "1.00000E+11"
+  sprintf('%#G', 0.000000000001)  # => "1.00000E-12"
+
+==== Specifier +o+
+
+Format +argument+ as an octal integer.
+If +argument+ is negative, it will be formatted as a two's complement
+prefixed with +..7+:
+
+  sprintf('%o', 16)   # => "20"
+
+  # Prefix '..7' for negative value.
+  sprintf('%o', -16)  # => "..760"
+
+  # Prefix zero for alternate format if positive.
+  sprintf('%#o', 16)  # => "020"
+  sprintf('%#o', -16) # => "..760"
+
+==== Specifier +p+
+
+Format +argument+ as a string via <tt>argument.inspect</tt>:
+
+  t = Time.now
+  sprintf('%p', t)   # => "2022-05-01 13:42:07.1645683 -0500"
+
+==== Specifier +s+
+
+Format +argument+ as a string via <tt>argument.to_s</tt>:
+
+  t = Time.now
+  sprintf('%s', t) # => "2022-05-01 13:42:07 -0500"
+
+Flag <tt>'#'</tt> does not apply.
+
+==== Specifiers +x+ and +X+
+
+Format +argument+ as a hexadecimal integer.
+If +argument+ is negative, it will be formatted as a two's complement
+prefixed with +..f+:
+
+  sprintf('%x', 100)   # => "64"
+
+  # Prefix '..f' for negative value.
+  sprintf('%x', -100)  # => "..f9c"
+
+  # Use alternate format.
+  sprintf('%#x', 100)  # => "0x64"
+
+  # Alternate format for negative value.
+  sprintf('%#x', -100) # => "0x..f9c"
+
+==== Specifier <tt>%</tt>
+
+Format +argument+ (<tt>'%'</tt>) as a single percent character:
+
+  sprintf('%d %%', 100) # => "100 %"
+
+Flags do not apply.
+
+=== Reference by Name
+
+For more complex formatting, Ruby supports a reference by name.
+%<name>s style uses format style, but %{name} style doesn't.
+
+Examples:
+
+  sprintf("%<foo>d : %<bar>f", { :foo => 1, :bar => 2 }) # => 1 : 2.000000
+  sprintf("%{foo}f", { :foo => 1 })                      # => "1f"

+== Implicit Conversions
+
+Some Ruby methods accept one or more objects
+that can be either:
+
+* <i>Of a given class</i>, and so accepted as is.
+* <i>Implicitly convertible to that class</i>, in which case
+  the called method converts the object.
+
+For each of the relevant classes, the conversion is done by calling
+a specific conversion method:
+
+* Array: +to_ary+
+* Hash: +to_hash+
+* Integer: +to_int+
+* String: +to_str+
+
+=== Array-Convertible Objects
+
+An <i>Array-convertible object</i> is an object that:
+
+* Has instance method +to_ary+.
+* The method accepts no arguments.
+* The method returns an object +obj+ for which <tt>obj.kind_of?(Array)</tt> returns +true+.
+
+The Ruby core class that satisfies these requirements is:
+
+* Array
+
+The examples in this section use method <tt>Array#replace</tt>,
+which accepts an Array-convertible argument.
+
+This class is Array-convertible:
+
+    class ArrayConvertible
+      def to_ary
+        [:foo, 'bar', 2]
+      end
+    end
+    a = []
+    a.replace(ArrayConvertible.new) # => [:foo, "bar", 2]
+
+This class is not Array-convertible (no +to_ary+ method):
+
+    class NotArrayConvertible; end
+    a = []
+    # Raises TypeError (no implicit conversion of NotArrayConvertible into Array)
+    a.replace(NotArrayConvertible.new)
+
+This class is not Array-convertible (method +to_ary+ takes arguments):
+
+    class NotArrayConvertible
+      def to_ary(x)
+        [:foo, 'bar', 2]
+      end
+    end
+    a = []
+    # Raises ArgumentError (wrong number of arguments (given 0, expected 1))
+    a.replace(NotArrayConvertible.new)
+
+This class is not Array-convertible (method +to_ary+ returns non-Array):
+
+    class NotArrayConvertible
+      def to_ary
+        :foo
+      end
+    end
+    a = []
+    # Raises TypeError (can't convert NotArrayConvertible to Array (NotArrayConvertible#to_ary gives Symbol))
+    a.replace(NotArrayConvertible.new)
+
+=== Hash-Convertible Objects
+
+A <i>Hash-convertible object</i> is an object that:
+
+* Has instance method +to_hash+.
+* The method accepts no arguments.
+* The method returns an object +obj+ for which <tt>obj.kind_of?(Hash)</tt> returns +true+.
+
+The Ruby core class that satisfies these requirements is:
+
+* Hash
+
+The examples in this section use method <tt>Hash#merge</tt>,
+which accepts a Hash-convertible argument.
+
+This class is Hash-convertible:
+
+    class HashConvertible
+      def to_hash
+        {foo: 0, bar: 1, baz: 2}
+      end
+    end
+    h = {}
+    h.merge(HashConvertible.new) # => {:foo=>0, :bar=>1, :baz=>2}
+
+This class is not Hash-convertible (no +to_hash+ method):
+
+    class NotHashConvertible; end
+    h = {}
+    # Raises TypeError (no implicit conversion of NotHashConvertible into Hash)
+    h.merge(NotHashConvertible.new)
+
+This class is not Hash-convertible (method +to_hash+ takes arguments):
+
+    class NotHashConvertible
+      def to_hash(x)
+        {foo: 0, bar: 1, baz: 2}
+      end
+    end
+    h = {}
+    # Raises ArgumentError (wrong number of arguments (given 0, expected 1))
+    h.merge(NotHashConvertible.new)
+
+This class is not Hash-convertible (method +to_hash+ returns non-Hash):
+
+    class NotHashConvertible
+      def to_hash
+        :foo
+      end
+    end
+    h = {}
+    # Raises TypeError (can't convert NotHashConvertible to Hash (ToHashReturnsNonHash#to_hash gives Symbol))
+    h.merge(NotHashConvertible.new)
+
+=== Integer-Convertible Objects
+
+An <i>Integer-convertible object</i> is an object that:
+
+* Has instance method +to_int+.
+* The method accepts no arguments.
+* The method returns an object +obj+ for which <tt>obj.kind_of?(Integer)</tt> returns +true+.
+
+The Ruby core classes that satisfy these requirements are:
+
+* Integer
+* Float
+* Complex
+* Rational
+
+The examples in this section use method <tt>Array.new</tt>,
+which accepts an Integer-convertible argument.
+
+This user-defined class is Integer-convertible:
+
+    class IntegerConvertible
+      def to_int
+        3
+      end
+    end
+    a = Array.new(IntegerConvertible.new).size
+    a # => 3
+
+This class is not Integer-convertible (method +to_int+ takes arguments):
+
+    class NotIntegerConvertible
+      def to_int(x)
+        3
+      end
+    end
+    # Raises ArgumentError (wrong number of arguments (given 0, expected 1))
+    Array.new(NotIntegerConvertible.new)
+
+This class is not Integer-convertible (method +to_int+ returns non-Integer):
+
+    class NotIntegerConvertible
+      def to_int
+        :foo
+      end
+    end
+    # Raises TypeError (can't convert NotIntegerConvertible to Integer (NotIntegerConvertible#to_int gives Symbol))
+    Array.new(NotIntegerConvertible.new)
+
+=== String-Convertible Objects
+
+A <i>String-convertible object</i> is an object that:
+* Has instance method +to_str+.
+* The method accepts no arguments.
+* The method returns an object +obj+ for which <tt>obj.kind_of?(String)</tt> returns +true+.
+
+The Ruby core class that satisfies these requirements is:
+
+* String
+
+The examples in this section use method <tt>String::new</tt>,
+which accepts a String-convertible argument.
+
+This class is String-convertible:
+
+    class StringConvertible
+      def to_str
+        'foo'
+      end
+    end
+    String.new(StringConvertible.new) # => "foo"
+
+This class is not String-convertible (no +to_str+ method):
+
+    class NotStringConvertible; end
+    # Raises TypeError (no implicit conversion of NotStringConvertible into String)
+    String.new(NotStringConvertible.new)
+
+This class is not String-convertible (method +to_str+ takes arguments):

-
-=begin
-= What is irb?
-
-irb stands for `interactive ruby'. irb is a tool to execute interactively
-ruby expressions read from stdin. 
-
-= Invoking
-
-  % irb
-
-= Usage
-
-Use of irb is easy if you know ruby.  Executing irb, prompts are 
-displayed as follows. Then, enter expression of ruby. A input is
-executed when it is syntacticaly completed. 
-
-  dim% irb
-  irb(main):001:0> 1+2
-  3
-  irb(main):002:0> class Foo
-  irb(main):003:1>  def foo
-  irb(main):004:2>    print 1
-  irb(main):005:2>  end
-  irb(main):006:1> end
-  nil
-  irb(main):007:0> 
-
-And, Readline extesion module can be used with irb. Using Readline
-is the standard default action if Readline is installed. 
-
-= Command line option
-
-  irb.rb [options] file_name opts
-  options:
-  -f		    suppress read ~/.irbrc 
-  -m		    bc mode (fraction or matrix are available)
-  -d                set $DEBUG  to true (same as `ruby -d')
-  -Kc		    same as `ruby -Kc'
-  -r load-module    same as `ruby -r'
-  --verbose	    command input is echoed(default)
-  --noverbose	    command input isn't echoed
-  --echo	    commands are echoed immediately before execution(default)
-  --noecho	    commands aren't echoed immediately before execution
-  --inspect	    uses `inspect' for output (the default except bc mode)
-  --noinspect	    doesn't uses inspect for output
-  --readline	    uses Readline extension module
-  --noreadline	    doesn't use Readline extension module
-  --prompt prompt-mode
-  --prompt-mode prompt-mode
-		    switches prompt mode. Pre-defined prompt modes are
-		    `default', `simple', `xmp' and `inf-ruby'
-			    
-  --inf-ruby-mode   uses prompt appreciate for inf-ruby-mode on emacs. 
-		    Suppresses --readline. 
-  --simple-prompt   simple prompt mode
-  --noprompt	    no prompt
-  --tracer	    display trace for each execution of commands.
-  --back-trace-limit n
-		    displayes backtrace top n and tail n. The default
-		    value is 16. 
-  --irb_debug n	    sets internal debug level to n (It shouldn't be used)
-  -v, --version	    prints the version of irb
-
-= Configurations
-
-irb reads `~/.irbrc' when it is invoked. If `~/.irbrb' doesn't exist
-irb try to read in the order `.irbrc', `irb.rc', `_irbrc' then `$irbrc'. 
-
-The following is altanative to the command line option. To use them
-type as follows in an irb session. 
-
-  IRB.conf[:IRB_NAME]="irb"
-  IRB.conf[:MATH_MODE]=false
-  IRB.conf[:USE_TRACER]=false
-  IRB.conf[:USE_LOADER]=false
-  IRB.conf[:IGNORE_SIGINT]=true
-  IRB.conf[:IGNORE_EOF]=false
-  IRB.conf[:INSPECT_MODE]=nil
-  IRB.conf[:IRB_RC] = nil
-  IRB.conf[:BACK_TRACE_LIMIT]=16
-  IRB.conf[:USE_LOADER] = false
-  IRB.conf[:USE_READLINE] = nil
-  IRB.conf[:USE_TRACER] = false
-  IRB.conf[:IGNORE_SIGINT] = true
-  IRB.conf[:IGNORE_EOF] = false
-  IRB.conf[:PROMPT_MODE] = :DEFALUT
-  IRB.conf[:PROMPT] = {...}
-  IRB.conf[:DEBUG_LEVEL]=0
-  IRB.conf[:VERBOSE]=true
-
-== Customizing prompt
-
-To costomize the prompt you set a variable
-
-  IRB.conf[:PROMPT]
-
-For example, describe as follows in `.irbrc'. 
-
-  IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
-    :PROMPT_I => nil,		  # normal prompt
-    :PROMPT_S => nil,		  # prompt for continuated strings
-    :PROMPT_C => nil,		  # prompt for continuated statement
-    :RETURN => "    ==>%s\n"	  # format to return value
-  }
-
-Then, invoke irb with the above prompt mode by
-
-  % irb --prompt my-prompt
-
-Or add the following in `.irbrc'. 
-
-  IRB.conf[:PROMPT_MODE] = :MY_PROMPT
-
-Constants PROMPT_I, PROMPT_S and PROMPT_C specifies the format. 
-In the prompt specification, some special strings are available. 
-
-  %N	command name which is running
-  %m	to_s of main object (self)
-  %M	inspect of main object (self)
-  %l	type of string(", ', /, ]), `]' is inner %w[...]
-  %NNi	indent level. NN is degits and means as same as printf("%NNd"). 
-        It can be ommited
-  %NNn	line number. 
-  %%    %
-
-For instance, the default prompt mode is defined as follows:
-
-IRB.conf[:PROMPT_MODE][:DEFAULT] = {
-      :PROMPT_I => "%N(%m):%03n:%i> ",
-      :PROMPT_S => "%N(%m):%03n:%i%l ",
-      :PROMPT_C => "%N(%m):%03n:%i* ",
-      :RETURN => "%s\n"
-} 
-
-RETURN is used to printf. 
-
-== Configurating subirb
-
-The command line option or IRB.conf specify the default behavior of
-(sub)irb. On the other hand, each conf of in the next sction `6. Command' 
-is used to individually configurate (sub)irb. 
-
-If proc is set to IRB.conf[:IRB_RC], its subirb will be invoked after
-execution of that proc under giving the context of irb as its
-aregument. By this mechanism each subirb can be configurated. 
-
-= Command
-
-For irb commands, both simple name and `irb_'-prefixed name are prepared. 
-

-= Restrictions
-
-Because irb evaluates the inputs immediately after the imput is
-syntactically completed, irb gives slight different result than
-directly use ruby. Known difference is pointed out here. 
-
-
-== Declaration of the local variable
-
-The following causes an error in ruby:
-
-  eval "foo = 0"
-  foo
-  --
-  -:2: undefined local variable or method `foo' for #<Object:0x40283118> (NameError)
-  ---
-  NameError
-
-Though, the above will successfully done by irb. 
-
-  >> eval "foo = 0"
- => 0
- >> foo
- => 0
-
-Ruby evaluates a code after reading entire of code and determination
-of the scope of local variables. On the other hand, irb do
-immediately. More precisely, irb evaluate at first
-
-  evel "foo = 0" 
-
-then foo is defined on this timing. It is because of this
-incompatibility.
-
-If you'd like to detect those differences, begin...end can be used:
-
-  >> begin
-  ?>   eval "foo = 0"
-  >>   foo
-  >> end
-  NameError: undefined local variable or method `foo' for #<Object:0x4013d0f0>
-  (irb):3
-  (irb_local_binding):1:in `eval'
-
-== Here-document
-
-Implementation of Here-document is incomplete. 
-
-== Symbol
-
-Irb can not always recognize a symbol as to be Symbol. Concretely, an
-expression have completed, however Irb regard it as continuation line.

+= Maintainers
+
+This page describes the current module, library, and extension maintainers of Ruby.
+
+== Module Maintainers
+
+A module maintainer is responsible for a certain part of Ruby.
+
+* The maintainer fixes bugs of the part. Particularly, they should fix security vulnerabilities as soon as possible.
+* They handle issues related the module on the Redmine or ML.
+* They may be discharged by the 3 months rule [ruby-core:25764].
+* They have commit right to Ruby's repository to modify their part in the repository.
+* They have "developer" role on the Redmine to modify issues.
+* They have authority to decide the feature of their part. But they should always respect discussions on ruby-core/ruby-dev.
+
+A submaintainer of a module is like a maintainer. But the submaintainer does
+not have authority to change/add a feature on his/her part. They need consensus
+on ruby-core/ruby-dev before changing/adding. Some of submaintainers have
+commit right, others don't.

+= Marshal Format
+
+The Marshal format is used to serialize ruby objects.  The format can store
+arbitrary objects through three user-defined extension mechanisms.
+
+For documentation on using Marshal to serialize and deserialize objects, see
+the Marshal module.
+
+This document calls a serialized set of objects a stream.  The Ruby
+implementation can load a set of objects from a String, an IO or an object
+that implements a +getc+ method.
+
+== Stream Format
+
+The first two bytes of the stream contain the major and minor version, each as
+a single byte encoding a digit.  The version implemented in Ruby is 4.8
+(stored as "\x04\x08") and is supported by ruby 1.8.0 and newer.
+
+Different major versions of the Marshal format are not compatible and cannot
+be understood by other major versions.  Lesser minor versions of the format
+can be understood by newer minor versions.  Format 4.7 can be loaded by a 4.8
+implementation but format 4.8 cannot be loaded by a 4.7 implementation.
+
+Following the version bytes is a stream describing the serialized object.  The
+stream contains nested objects (the same as a Ruby object) but objects in the
+stream do not necessarily have a direct mapping to the Ruby object model.
+
+Each object in the stream is described by a byte indicating its type followed
+by one or more bytes describing the object.  When "object" is mentioned below
+it means any of the types below that defines a Ruby object.
+
+=== true, false, nil
+
+These objects are each one byte long.  "T" is represents +true+, "F"
+represents +false+ and "0" represents +nil+.
+
+=== Fixnum and long
+
+"i" represents a signed 32 bit value using a packed format.  One through five
+bytes follows the type.  The value loaded will always be a Fixnum.  On
+32 bit platforms (where the precision of a Fixnum is less than 32 bits)
+loading large values will cause overflow on CRuby.
+
+The fixnum type is used to represent both ruby Fixnum objects and the sizes of
+marshaled arrays, hashes, instance variables and other types.  In the
+following sections "long" will mean the format described below, which supports
+full 32 bit precision.
+
+The first byte has the following special values:
+
+"\x00"::
+  The value of the integer is 0.  No bytes follow.
+
+"\x01"::
+  The total size of the integer is two bytes.  The following byte is a
+  positive integer in the range of 0 through 255.  Only values between 123
+  and 255 should be represented this way to save bytes.
+
+"\xff"::
+  The total size of the integer is two bytes.  The following byte is a
+  negative integer in the range of -1 through -256.
+
+"\x02"::
+  The total size of the integer is three bytes.  The following two bytes are a
+  positive little-endian integer.
+
+"\xfe"::
+  The total size of the integer is three bytes.  The following two bytes are a
+  negative little-endian integer.
+
+"\x03"::
+  The total size of the integer is four bytes.  The following three bytes are
+  a positive little-endian integer.
+
+"\xfd"::
+  The total size of the integer is four bytes.  The following three bytes are a
+  negative little-endian integer.
+
+"\x04"::
+  The total size of the integer is five bytes.  The following four bytes are a
+  positive little-endian integer.  For compatibility with 32 bit ruby,
+  only Fixnums less than 1073741824 should be represented this way.  For sizes
+  of stream objects full precision may be used.

+  The total size of the integer is five bytes.  The following four bytes are a
+  negative little-endian integer.  For compatibility with 32 bit ruby,
+  only Fixnums greater than -10737341824 should be represented this way.  For
+  sizes of stream objects full precision may be used.
+
+Otherwise the first byte is a sign-extended eight-bit value with an offset.
+If the value is positive the value is determined by subtracting 5 from the
+value.  If the value is negative the value is determined by adding 5 to the
+value.
+
+There are multiple representations for many values.  CRuby always outputs the
+shortest representation possible.
+
+=== Symbols and Byte Sequence
+
+":" represents a real symbol.  A real symbol contains the data needed to
+define the symbol for the rest of the stream as future occurrences in the
+stream will instead be references (a symbol link) to this one.  The reference
+is a zero-indexed 32 bit value (so the first occurrence of <code>:hello</code>
+is 0).
+
+Following the type byte is byte sequence which consists of a long indicating
+the number of bytes in the sequence followed by that many bytes of data.  Byte
+sequences have no encoding.
+
+For example, the following stream contains the Symbol <code>:hello</code>:
+
+  "\x04\x08:\x0ahello"
+
+";" represents a Symbol link which references a previously defined Symbol.
+Following the type byte is a long containing the index in the lookup table for
+the linked (referenced) Symbol.
+
+For example, the following stream contains <code>[:hello, :hello]</code>:
+
+  "\x04\b[\a:\nhello;\x00"
+
+When a "symbol" is referenced below it may be either a real symbol or a
+symbol link.
+
+=== Object References
+
+Separate from but similar to symbol references, the stream contains only one
+copy of each object (as determined by #object_id) for all objects except
+true, false, nil, Fixnums and Symbols (which are stored separately as
+described above) a one-indexed 32 bit value will be stored and reused when the
+object is encountered again.  (The first object has an index of 1).
+
+"@" represents an object link.  Following the type byte is a long giving the
+index of the object.
+
+For example, the following stream contains an Array of the same
+<code>"hello"</code> object twice:
+
+  "\004\b[\a\"\nhello@\006"
+
+=== Instance Variables
+
+"I" indicates that instance variables follow the next object.  An object
+follows the type byte.  Following the object is a length indicating the number
+of instance variables for the object.  Following the length is a set of
+name-value pairs.  The names are symbols while the values are objects.  The
+symbols must be instance variable names (<code>:@name</code>).
+
+An Object ("o" type, described below) uses the same format for its instance
+variables as described here.
+
+For a String and Regexp (described below) a special instance variable
+<code>:E</code> is used to indicate the Encoding.
+
+=== Extended
+
+"e" indicates that the next object is extended by a module.  An object follows
+the type byte.  Following the object is a symbol that contains the name of the
+module the object is extended by.
+
+=== Array
+
+"[" represents an Array.  Following the type byte is a long indicating the
+number of objects in the array.  The given number of objects follow the
+length.
+
+=== Bignum
+
+"l" represents a Bignum which is composed of three parts:
+
+sign::
+  A single byte containing "+" for a positive value or "-" for a negative
+  value.
+length::
+  A long indicating the number of bytes of Bignum data follows, divided by
+  two.  Multiply the length by two to determine the number of bytes of data
+  that follow.
+data::
+  Bytes of Bignum data representing the number.
+
+The following ruby code will reconstruct the Bignum value from an array of
+bytes:
+
+  result = 0
+
+  bytes.each_with_index do |byte, exp|
+   result += (byte * 2 ** (exp * 8))
+  end
+
+=== Class and Module
+
+"c" represents a Class object, "m" represents a Module and "M" represents
+either a class or module (this is an old-style for compatibility).  No class
+or module content is included, this type is only a reference.  Following the
+type byte is a byte sequence which is used to look up an existing class or
+module, respectively.
+
+Instance variables are not allowed on a class or module.
+
+If no class or module exists an exception should be raised.
+
+For "c" and "m" types, the loaded object must be a class or module,
+respectively.
+
+=== Data
+
+"d" represents a Data object.  (Data objects are wrapped pointers from ruby
+extensions.)  Following the type byte is a symbol indicating the class for the
+Data object and an object that contains the state of the Data object.
+
+To dump a Data object Ruby calls _dump_data.  To load a Data object Ruby calls
+_load_data with the state of the object on a newly allocated instance.
+
+=== Float
+
+"f" represents a Float object.  Following the type byte is a byte sequence
+containing the float value.  The following values are special:
+
+"inf"::
+  Positive infinity
+
+"-inf"::
+  Negative infinity
+
+"nan"::
+  Not a Number
+
+Otherwise the byte sequence contains a C double (loadable by strtod(3)).
+Older minor versions of Marshal also stored extra mantissa bits to ensure
+portability across platforms but 4.8 does not include these.  See
+[ruby-talk:69518] for some explanation.
+
+=== Hash and Hash with Default Value
+
+"{" represents a Hash object while "}" represents a Hash with a default value
+set (<code>Hash.new 0</code>).  Following the type byte is a long indicating
+the number of key-value pairs in the Hash, the size.  Double the given number
+of objects follow the size.
+
+For a Hash with a default value, the default value follows all the pairs.
+
+=== Module and Old Module
+
+=== Object
+
+"o" represents an object that doesn't have any other special form (such as
+a user-defined or built-in format).  Following the type byte is a symbol
+containing the class name of the object.  Following the class name is a long
+indicating the number of instance variable names and values for the object.
+Double the given number of pairs of objects follow the size.
+
+The keys in the pairs must be symbols containing instance variable names.
+
+=== Regular Expression
+
+"/" represents a regular expression.  Following the type byte is a byte
+sequence containing the regular expression source.  Following the type byte is
+a byte containing the regular expression options (case-insensitive, etc.) as a
+signed 8-bit value.
+
+Regular expressions can have an encoding attached through instance variables
+(see above).  If no encoding is attached escapes for the following regexp
+specials not present in ruby 1.8 must be removed: g-m, o-q, u, y, E, F, H-L,
+N-V, X, Y.
+
+=== String
+
+'"' represents a String.  Following the type byte is a byte sequence
+containing the string content.  When dumped from ruby 1.9 an encoding instance
+variable (<code>:E</code> see above) should be included unless the encoding is
+binary.
+
+=== Struct
+
+"S" represents a Struct.  Following the type byte is a symbol containing the
+name of the struct.  Following the name is a long indicating the number of
+members in the struct.  Double the number of objects follow the member count.
+Each member is a pair containing the member's symbol and an object for the
+value of that member.
+
+If the struct name does not match a Struct subclass in the running ruby an
+exception should be raised.
+
+If there is a mismatch between the struct in the currently running ruby and
+the member count in the marshaled struct an exception should be raised.
+
+=== User Class
+
+"C" represents a subclass of a String, Regexp, Array or Hash.  Following the
+type byte is a symbol containing the name of the subclass.  Following the name
+is the wrapped object.
+
+=== User Defined
+
+"u" represents an object with a user-defined serialization format using the
++_dump+ instance method and +_load+ class method.  Following the type byte is
+a symbol containing the class name.  Following the class name is a byte
+sequence containing the user-defined representation of the object.
+
+The class method +_load+ is called on the class with a string created from the
+byte-sequence.
+
+=== User Marshal
+
+"U" represents an object with a user-defined serialization format using the
++marshal_dump+ and +marshal_load+ instance methods.  Following the type byte
+is a symbol containing the class name.  Following the class name is an object
+containing the data.
+
+Upon loading a new instance must be allocated and +marshal_load+ must be
+called on the instance with the data.

+\Module \Math provides methods for basic trigonometric,

+# MemoryView
+
+MemoryView provides the features to share multidimensional homogeneous arrays of
+fixed-size element on memory among extension libraries.
+
+## Disclaimer
+
+* This feature is still experimental.  The specification described here can be changed in the future.
+
+* This document is under construction.  Please refer the master branch of ruby for the latest version of this document.
+
+## Overview
+
+We sometimes deal with certain kinds of objects that have arrays of the same typed fixed-size elements on a contiguous memory area as its internal representation.
+Numo::NArray in numo-narray and Magick::Image in rmagick are typical examples of such objects.
+MemoryView plays the role of the hub to share the internal data of such objects without copy among such libraries.
+
+Copy-less sharing of data is very important in some field such as data analysis, machine learning, and image processing.  In these field, people need to handle large amount of on-memory data with several libraries.  If we are forced to copy to exchange large data among libraries, a large amount of the data processing time must be occupied by copying data.  You can avoid such wasting time by using MemoryView.
+
+MemoryView has two categories of APIs:
+
+1. Producer API
+
+    Classes can register own MemoryView entry which allows objects of that classes to expose their MemoryView
+
+2. Consumer API
+
+    Consumer API allows us to obtain and manage the MemoryView of an object
+
+## MemoryView structure
+
+A MemoryView structure, `rb_memory_view_t`, is used for exporting objects' MemoryView.
+This structure contains the reference of the object, which is the owner of the MemoryView, the pointer to the head of exported memory, and the metadata that describes the structure of the memory.  The metadata can describe multidimensional arrays with strides.
+
+### The member of MemoryView structure
+
+The MemoryView structure consists of the following members.
+
+- `VALUE obj`
+
+    The reference to the original object that has the memory exported via the MemoryView.
+
+    RubyVM manages the reference count of the MemoryView-exported objects to guard them from the garbage collection.  The consumers do not have to struggle to guard this object from GC.
+
+- `void *data`
+
+    The pointer to the head of the exported memory.
+
+- `ssize_t byte_size`
+
+    The number of bytes in the memory pointed by `data`.
+
+- `bool readonly`
+
+    `true` for readonly memory, `false` for writable memory.
+
+- `const char *format`
+
+    A string to describe the format of an element, or NULL for unsigned byte.
+
+- `ssize_t item_size`
+
+    The number of bytes in each element.
+
+- `const rb_memory_view_item_component_t *item_desc.components`
+
+    The array of the metadata of the component in an element.
+
+- `size_t item_desc.length`
+
+    The number of items in `item_desc.components`.
+
+- `ssize_t ndim`
+
+    The number of dimensions.
+
+- `const ssize_t *shape`
+
+    A `ndim` size array indicating the number of elements in each dimension.
+    This can be `NULL` when `ndim` is 1.
+
+- `const ssize_t *strides`
+
+    A `ndim` size array indicating the number of bytes to skip to go to the next element in each dimension.
+    This can be `NULL` when `ndim` is 1.
+
+- `const ssize_t *sub_offsets`
+
+    A `ndim` size array consisting of the offsets in each dimension when the MemoryView exposes a nested array.
+    This can be `NULL` when the MemoryView exposes a flat array.
+
+- `void *private_data`
+
+    The private data that MemoryView provider uses internally.
+    This can be `NULL` when any private data is unnecessary.
+
+## MemoryView APIs
+
+### For consumers
+
+- `bool rb_memory_view_available_p(VALUE obj)`
+
+    Return `true` if `obj` supports to export a MemoryView.  Return `false` otherwise.
+
+    If this function returns `true`, it doesn't mean the function `rb_memory_view_get` will succeed.
+
+- `bool rb_memory_view_get(VALUE obj, rb_memory_view_t *view, int flags)`
+
+    If the given `obj` supports to export a MemoryView that conforms the given `flags`, this function fills `view` by the information of the MemoryView and returns `true`.  In this case, the reference count of `obj` is increased.
+
+    If the given combination of `obj` and `flags` cannot export a MemoryView, this function returns `false`. The content of `view` is not touched in this case.
+
+    The exported MemoryView must be released by `rb_memory_view_release` when the MemoryView is no longer needed.
+
+- `bool rb_memory_view_release(rb_memory_view_t *view)`
+
+    Release the given MemoryView `view` and decrement the reference count of `view->obj`.
+
+    Consumers must call this function when the MemoryView is no longer needed.  Missing to call this function leads memory leak.
+
+- `ssize_t rb_memory_view_item_size_from_format(const char *format, const char **err)`
+
+    Calculate the number of bytes occupied by an element.
+
+    When the calculation fails, the failed location in `format` is stored into `err`, and returns `-1`.
+
+- `void *rb_memory_view_get_item_pointer(rb_memory_view_t *view, const ssize_t *indices)`
+
+    Calculate the location of the item indicated by the given `indices`.
+    The length of `indices` must equal to `view->ndim`.
+    This function initializes `view->item_desc` if needed.
+
+- `VALUE rb_memory_view_get_item(rb_memory_view_t *view, const ssize_t *indices)`
+
+    Return the Ruby object representation of the item indicated by the given `indices`.
+    The length of `indices` must equal to `view->ndim`.
+    This function uses `rb_memory_view_get_item_pointer`.
+
+- `rb_memory_view_init_as_byte_array(rb_memory_view_t *view, VALUE obj, void *data, const ssize_t len, const bool readonly)`
+
+  Fill the members of `view` as an 1-dimensional byte array.
+
+- `void rb_memory_view_fill_contiguous_strides(const ssize_t ndim, const ssize_t item_size, const ssize_t *const shape, const bool row_major_p, ssize_t *const strides)`
+
+  Fill the `strides` array with byte-Strides of a contiguous array of the given shape with the given element size.
+
+- `void rb_memory_view_prepare_item_desc(rb_memory_view_t *view)`
+
+  Fill the `item_desc` member of `view`.
+
+- `bool rb_memory_view_is_contiguous(const rb_memory_view_t *view)`
+
+  Return `true` if the data in the MemoryView `view` is row-major or column-major contiguous.
+
+  Return `false` otherwise.
+
+- `bool rb_memory_view_is_row_major_contiguous(const rb_memory_view_t *view)`
+
+  Return `true` if the data in the MemoryView `view` is row-major contiguous.
+
+  Return `false` otherwise.
+
+- `bool rb_memory_view_is_column_major_contiguous(const rb_memory_view_t *view)`
+
+  Return `true` if the data in the MemoryView `view` is column-major contiguous.
+
+  Return `false` otherwise.

+# MJIT
+
+This document has some tips that might be useful when you work on MJIT.
+
+## Supported platforms
+
+The following platforms are either tested on CI or assumed to work.
+
+* OS: Linux, macOS
+* Arch: x86\_64, aarch64, arm64, i686, i386
+
+### Not supported
+
+The MJIT support for the following platforms is no longer maintained.
+
+* OS: Windows (mswin, MinGW), Solaris
+* Arch: SPARC, s390x
+
+## Developing MJIT
+
+### Bindgen
+
+If you see an "MJIT bindgen" GitHub Actions failure, please commit the `git diff` shown on the failed job.
+
+For doing the same thing locally, run `make mjit-bindgen` after installing libclang.
+macOS seems to have libclang by default. On Ubuntu, you can install it with `apt install libclang1`.
+
+### Always run make install
+
+Always run `make install` before running MJIT. It could easily cause a SEGV if you don't.
+MJIT looks for the installed header for security reasons.
+
+### --mjit-debug vs --mjit-debug=-ggdb3
+
+`--mjit-debug=[flags]` allows you to specify arbitrary flags while keeping other compiler flags like `-O3`,
+which is useful for profiling benchmarks.
+
+`--mjit-debug` alone, on the other hand, disables `-O3` and adds debug flags.
+If you're debugging MJIT, what you need to use is not `--mjit-debug=-ggdb3` but `--mjit-debug`.

+Examples here assume that <tt>net/http</tt> has been required
+(which also requires +uri+):
+
+  require 'net/http'
+
+Many code examples here use these example websites:
+
+- https://jsonplaceholder.typicode.com.
+- http://example.com.
+
+Some examples also assume these variables:
+
+  uri = URI('https://jsonplaceholder.typicode.com/')
+  uri.freeze # Examples may not modify.
+  hostname = uri.hostname # => "jsonplaceholder.typicode.com"
+  path = uri.path         # => "/"
+  port = uri.port         # => 443
+
+So that example requests may be written as:
+
+  Net::HTTP.get(uri)
+  Net::HTTP.get(hostname, '/index.html')
+  Net::HTTP.start(hostname) do |http|
+    http.get('/todos/1')
+    http.get('/todos/2')
+  end
+
+An example that needs a modified URI first duplicates +uri+, then modifies the duplicate:
+
+  _uri = uri.dup
+  _uri.path = '/todos/1'

+
+- An identifier, which may be any object.
+- An optional match pattern, which defaults to <tt>/.*/m</tt>.
+- A block that accepts the argument and returns the converted value.
+
+This custom converter accepts any argument and converts it,
+if possible, to a \Complex object.
+
+  :include: ruby/custom_converter.rb
+
+Executions:
+
+  $ ruby custom_converter.rb --complex 0

+
+This custom converter accepts any 1-word argument
+and capitalizes it, if possible.
+
+  :include: ruby/match_converter.rb
+
+Executions:
+
+  $ ruby match_converter.rb --capitalize foo
+  ["Foo", String]
+  $ ruby match_converter.rb --capitalize "foo bar"
+  match_converter.rb:9:in `<main>': invalid argument: --capitalize foo bar (OptionParser::InvalidArgument)

+=== Option Names
+
+There are two kinds of option names:
+
+- Short option name, consisting of a single hyphen and a single character.
+- Long option name, consisting of two hyphens and one or more characters.
+
+==== Short Names
+
+===== Simple Short Names
+
+File +short_simple.rb+ defines two options:
+
+- One with short name <tt>-x</tt>.
+- The other with two short names, in effect, aliases, <tt>-1</tt> and <tt>-%</tt>.

+  ["-x", nil]
+  $ ruby short_optional.rb -x FOO
+  ["-x", "FOO"]
+
+===== Short Names from Range
+
+You can define an option with multiple short names
+taken from a range of characters.
+The parser yields both the actual character cited and the value.
+
+File +short_range.rb+ defines an option with short names
+for all printable characters from <tt>!</tt> to <tt>~</tt>:

+  long_required.rb:6:in `<main>': missing argument: --xxx (OptionParser::MissingArgument)
+  $ ruby long_required.rb --xxx FOO
+  ["--xxx", "FOO"]
+
+===== Long Names with Optional Arguments
+
+A long name followed (with whitespace) by a dummy word in square brackets
+defines an option that allows an optional argument.
+
+File +long_optional.rb+ defines an option <tt>--xxx</tt>
+that allows an optional argument.
+
+  :include: ruby/long_optional.rb
+
+Executions:
+
+  $ ruby long_optional.rb --help
+  Usage: long_optional [options]
+          --xxx [XXX]                  Long name with optional argument
+  $ ruby long_optional.rb --xxx
+  ["--xxx", nil]
+  $ ruby long_optional.rb --xxx FOO
+  ["--xxx", "FOO"]
+
+===== Long Names with Negation
+
+A long name may be defined with both positive and negative senses.
+
+File +long_with_negation.rb+ defines an option that has both senses.
+
+  :include: ruby/long_with_negation.rb
+
+Executions:
+
+  $ ruby long_with_negation.rb --help
+  Usage: long_with_negation [options]
+          --[no-]binary                Long name with negation
+  $ ruby long_with_negation.rb --binary
+  [true, TrueClass]
+  $ ruby long_with_negation.rb --no-binary
+  [false, FalseClass]
+
+==== Mixed Names
+
+An option may have both short and long names.
+
+File +mixed_names.rb+ defines a mixture of short and long names.
+
+  :include: ruby/mixed_names.rb
+
+Executions:
+
+  $ ruby mixed_names.rb --help
+Usage: mixed_names [options]
+    -x, --xxx                        Short and long, no argument
+    -y, --yyyYYY                     Short and long, required argument
+    -z, --zzz [ZZZ]                  Short and long, optional argument
+  $ ruby mixed_names.rb -x
+  ["--xxx", true]
+  $ ruby mixed_names.rb --xxx
+  ["--xxx", true]
+  $ ruby mixed_names.rb -y
+  mixed_names.rb:12:in `<main>': missing argument: -y (OptionParser::MissingArgument)
+  $ ruby mixed_names.rb -y FOO
+  ["--yyy", "FOO"]
+  $ ruby mixed_names.rb --yyy
+  mixed_names.rb:12:in `<main>': missing argument: --yyy (OptionParser::MissingArgument)
+  $ ruby mixed_names.rb --yyy BAR
+  ["--yyy", "BAR"]
+  $ ruby mixed_names.rb -z
+  ["--zzz", nil]
+  $ ruby mixed_names.rb -z BAZ
+  ["--zzz", "BAZ"]
+  $ ruby mixed_names.rb --zzz
+  ["--zzz", nil]
+  $ ruby mixed_names.rb --zzz BAT
+  ["--zzz", "BAT"]
+
+=== Argument Keywords
+
+As seen above, a given option name string may itself
+indicate whether the option has no argument, a required argument,
+or an optional argument.
+
+An alternative is to use a separate symbol keyword,
+which is one of <tt>:NONE</tt> (the default),
+<tt>:REQUIRED</tt>, <tt>:OPTIONAL</tt>.
+
+File +argument_keywords.rb+ defines an option with a required argument.
+
+  :include: ruby/argument_keywords.rb
+
+Executions:
+
+  $ ruby argument_keywords.rb --help
+  Usage: argument_keywords [options]
+      -x, --xxx                        Required argument
+  $ ruby argument_styles.rb --xxx
+  argument_styles.rb:6:in `<main>': missing argument: --xxx (OptionParser::MissingArgument)
+  $ ruby argument_styles.rb --xxx FOO
+  ["--xxx", "FOO"]
+
+=== Argument Strings
+
+Still another way to specify a required argument
+is to define it in a string separate from the name string.
+
+File +argument_strings.rb+ defines an option with a required argument.
+
+  :include: ruby/argument_strings.rb
+
+Executions:
+
+  $ ruby argument_strings.rb --help
+  Usage: argument_strings [options]
+      -x, --xxx=XXX                    Required argument
+  $ ruby argument_strings.rb --xxx
+  argument_strings.rb:9:in `<main>': missing argument: --xxx (OptionParser::MissingArgument)
+  $ ruby argument_strings.rb --xxx FOO
+  ["--xxx", "FOO"]
+
+=== Argument Values
+
+Permissible argument values may be restricted
+either by specifying explicit values
+or by providing a pattern that the given value must match.
+
+==== Explicit Argument Values
+
+You can specify argument values in either of two ways:
+
+- Specify values an array of strings.
+- Specify values a hash.
+
+===== Explicit Values in Array
+
+You can specify explicit argument values in an array of strings.
+The argument value must be one of those strings, or an unambiguous abbreviation.
+
+File +explicit_array_values.rb+ defines options with explicit argument values.
+
+  :include: ruby/explicit_array_values.rb
+
+Executions:
+
+  $ ruby explicit_array_values.rb --help
+  Usage: explicit_array_values [options]
+      -xXXX                            Values for required argument
+      -y [YYY]                         Values for optional argument
+  $ ruby explicit_array_values.rb -x
+  explicit_array_values.rb:9:in `<main>': missing argument: -x (OptionParser::MissingArgument)
+  $ ruby explicit_array_values.rb -x foo
+  ["-x", "foo"]
+  $ ruby explicit_array_values.rb -x f
+  ["-x", "foo"]
+  $ ruby explicit_array_values.rb -x bar
+  ["-x", "bar"]
+  $ ruby explicit_array_values.rb -y ba
+  explicit_array_values.rb:9:in `<main>': ambiguous argument: -y ba (OptionParser::AmbiguousArgument)
+  $ ruby explicit_array_values.rb -x baz
+  explicit_array_values.rb:9:in `<main>': invalid argument: -x baz (OptionParser::InvalidArgument)
+
+
+===== Explicit Values in Hash
+
+You can specify explicit argument values in a hash with string keys.
+The value passed must be one of those keys, or an unambiguous abbreviation;
+the value yielded will be the value for that key.
+
+File +explicit_hash_values.rb+ defines options with explicit argument values.
+
+  :include: ruby/explicit_hash_values.rb
+
+Executions:
+
+  $ ruby explicit_hash_values.rb --help
+  Usage: explicit_hash_values [options]
+      -xXXX                            Values for required argument
+      -y [YYY]                         Values for optional argument
+  $ ruby explicit_hash_values.rb -x
+  explicit_hash_values.rb:9:in `<main>': missing argument: -x (OptionParser::MissingArgument)
+  $ ruby explicit_hash_values.rb -x foo
+  ["-x", 0]
+  $ ruby explicit_hash_values.rb -x f
+  ["-x", 0]
+  $ ruby explicit_hash_values.rb -x bar
+  ["-x", 1]
+  $ ruby explicit_hash_values.rb -x baz
+  explicit_hash_values.rb:9:in `<main>': invalid argument: -x baz (OptionParser::InvalidArgument)
+  $ ruby explicit_hash_values.rb -y
+  ["-y", nil]
+  $ ruby explicit_hash_values.rb -y baz
+  ["-y", 2]
+  $ ruby explicit_hash_values.rb -y bat
+  ["-y", 3]
+  $ ruby explicit_hash_values.rb -y ba
+  explicit_hash_values.rb:9:in `<main>': ambiguous argument: -y ba (OptionParser::AmbiguousArgument)
+  $ ruby explicit_hash_values.rb -y bam
+  ["-y", nil]
+
+==== Argument Value Patterns
+
+You can restrict permissible argument values
+by specifying a Regexp that the given argument must match.
+
+File +matched_values.rb+ defines options with matched argument values.
+
+  :include: ruby/matched_values.rb
+
+Executions:
+
+  $ ruby matched_values.rb --help
+  Usage: matched_values [options]
+          --xxx XXX                    Matched values
+  $ ruby matched_values.rb --xxx foo
+  ["--xxx", "foo"]
+  $ ruby matched_values.rb --xxx FOO
+  ["--xxx", "FOO"]
+  $ ruby matched_values.rb --xxx bar
+  matched_values.rb:6:in `<main>': invalid argument: --xxx bar (OptionParser::InvalidArgument)
+
+=== Argument Converters
+
+An option can specify that its argument is to be converted
+from the default \String to an instance of another class.
+
+There are a number of built-in converters.
+You can also define custom converters.
+
+See {Argument Converters}[./argument_converters.rdoc].
+
+=== Descriptions
+
+A description parameter is any string parameter
+that is not recognized as an
+{option name}[#label-Option+Names] or a
+{terminator}[#label-Terminators];
+in other words, it does not begin with a hyphen.
+
+You may give any number of description parameters;
+each becomes a line in the text generated by option <tt>--help</tt>.
+
+File +descriptions.rb+ has six strings in its array +descriptions+.
+These are all passed as parameters to OptionParser#on, so that they
+all, line for line, become the option's description.
+
+  :include: ruby/descriptions.rb
+
+Executions:
+
+  $ ruby descriptions.rb --help
+  Usage: descriptions [options]
+          --xxx                        Lorem ipsum dolor sit amet, consectetuer
+                                       adipiscing elit. Aenean commodo ligula eget.
+                                       Aenean massa. Cum sociis natoque penatibus
+                                       et magnis dis parturient montes, nascetur
+                                       ridiculus mus. Donec quam felis, ultricies
+                                       nec, pellentesque eu, pretium quis, sem.
+  $ ruby descriptions.rb --xxx
+  ["--xxx", true]
+
+=== Option Handlers
+
+The handler for an option is an executable that will be called
+when the option is encountered.  The handler may be:
+
+- A block (this is most often seen).
+- A proc.
+- A method.
+
+==== Handler Blocks
+
+An option handler may be a block.
+
+File +block.rb+ defines an option that has a handler block.
+
+  :include: ruby/block.rb
+
+Executions:
+
+  $ ruby block.rb --help
+  Usage: block [options]
+          --xxx                        Option with no argument
+          --yyy YYY                    Option with required argument
+  $ ruby block.rb --xxx
+  ["Handler block for -xxx called with value:", true]
+  $ ruby block.rb --yyy FOO
+  ["Handler block for -yyy called with value:", "FOO"]
+
+==== Handler Procs
+
+An option handler may be a Proc.
+
+File +proc.rb+ defines an option that has a handler proc.
+
+  :include: ruby/proc.rb
+
+Executions:
+
+  $ ruby proc.rb --help
+  Usage: proc [options]
+          --xxx                        Option with no argument
+          --yyy YYY                    Option with required argument
+  $ ruby proc.rb --xxx
+  ["Handler proc for -xxx called with value:", true]
+  $ ruby proc.rb --yyy FOO
+  ["Handler proc for -yyy called with value:", "FOO"]
+
+==== Handler Methods
+
+An option handler may be a Method.
+
+File +proc.rb+ defines an option that has a handler method.
+
+  :include: ruby/method.rb
+
+Executions:
+
+  $ ruby method.rb --help
+  Usage: method [options]
+          --xxx                        Option with no argument
+          --yyy YYY                    Option with required argument
+  $ ruby method.rb --xxx
+  ["Handler method for -xxx called with value:", true]
+  $ ruby method.rb --yyy FOO
+  ["Handler method for -yyy called with value:", "FOO"]

+== Tutorial
+
+=== Why \OptionParser?
+
+When a Ruby program executes, it captures its command-line arguments
+and options into variable ARGV.
+This simple program just prints its \ARGV:
+
+  :include: ruby/argv.rb
+
+Execution, with arguments and options:
+
+  $ ruby argv.rb foo --bar --baz bat bam
+  ["foo", "--bar", "--baz", "bat", "bam"]
+
+The executing program is responsible for parsing and handling
+the command-line options.
+
+OptionParser offers methods for parsing and handling those options.
+
+With \OptionParser, you can define options so that for each option:
+
+- The code that defines the option and code that handles that option
+  are in the same place.
+- The option may take no argument, a required argument, or an optional argument.
+- The argument may be automatically converted to a specified class.
+- The argument may be restricted to specified _forms_.
+- The argument may be restricted to specified _values_.
+
+The class also has method #help, which displays automatically-generated help text.

+
+=== To Begin With
+
+To use \OptionParser:
+
+1. Require the \OptionParser code.
+2. Create an \OptionParser object.
+3. Define one or more options.
+4. Parse the command line.
+
+File +basic.rb+ defines three options, <tt>-x</tt>,
+<tt>-y</tt>, and <tt>-z</tt>, each with a descriptive string,
+and each with a block.
+
+  :include: ruby/basic.rb
+
+From these defined options, the parser automatically builds help text:
+
+  $ ruby basic.rb --help
+  Usage: basic [options]
+      -x                               Whether to X
+      -y                               Whether to Y
+      -z                               Whether to Z
+
+When an option is found during parsing,
+the block defined for the option is called with the argument value.
+An invalid option raises an exception.
+
+Method #parse!, which is used most often in this tutorial,
+removes from \ARGV the options and arguments it finds,
+leaving other non-option arguments for the program to handle on its own.
+The method returns the possibly-reduced \ARGV array.
+
+Executions:

+
+=== Defining Options
+
+A common way to define an option in \OptionParser
+is with instance method OptionParser#on.
+
+The method may be called with any number of arguments
+(whose order does not matter),
+and may also have a trailing optional keyword argument +into+.
+
+The given arguments determine the characteristics of the new option.
+These may include:
+
+- One or more short option names.
+- One or more long option names.
+- Whether the option takes no argument, an optional argument, or a required argument.
+- Acceptable _forms_ for the argument.
+- Acceptable _values_ for the argument.
+- A proc or method to be called when the parser encounters the option.
+- String descriptions for the option.
+
+=== Option Names
+
+You can give an option one or more names of two types:
+
+- Short (1-character) name, beginning with one hyphen (<tt>-</tt>).
+- Long (multi-character) name, beginning with two hyphens (<tt>--</tt>).
+
+==== Short Option Names
+
+A short option name consists of a hyphen and a single character.
+
+File +short_names.rb+
+defines an option with a short name, <tt>-x</tt>,
+and an option with two short names (aliases, in effect) <tt>-y</tt> and <tt>-z</tt>.
+
+  :include: ruby/short_names.rb
+
+Executions:
+
+  $ ruby short_names.rb --help
+  Usage: short_names [options]
+      -x                               Short name
+      -1, -%                           Two short names
+  $ ruby short_names.rb -x
+  ["x", true]
+  $ ruby short_names.rb -1
+  ["-1 or -%", true]
+  $ ruby short_names.rb -%
+  ["-1 or -%", true]
+
+Multiple short names can "share" a hyphen:
+
+  $ ruby short_names.rb -x1%
+  ["x", true]
+  ["-1 or -%", true]
+  ["-1 or -%", true]
+
+==== Long Option Names
+
+A long option name consists of two hyphens and a one or more characters
+(usually two or more characters).
+
+File +long_names.rb+
+defines an option with a long name, <tt>--xxx</tt>,
+and an option with two long names (aliases, in effect) <tt>--y1%</tt> and <tt>--z2#</tt>.
+
+  :include: ruby/long_names.rb
+
+Executions:
+
+  $ ruby long_names.rb --help
+  Usage: long_names [options]
+          --xxx                        Long name
+          --y1%, --z2#                 Two long names
+  $ ruby long_names.rb --xxx
+  ["-xxx", true]
+  $ ruby long_names.rb --y1%
+  ["--y1% or --z2#", true]
+  $ ruby long_names.rb --z2#
+  ["--y1% or --z2#", true]
+
+A long name may be defined with both positive and negative senses.
+
+File +long_with_negation.rb+ defines an option that has both senses.
+
+  :include: ruby/long_with_negation.rb
+
+Executions:
+
+  $ ruby long_with_negation.rb --help
+  Usage: long_with_negation [options]
+          --[no-]binary                Long name with negation
+  $ ruby long_with_negation.rb --binary
+  [true, TrueClass]
+  $ ruby long_with_negation.rb --no-binary
+  [false, FalseClass]
+
+==== Mixing Option Names
+
+Many developers like to mix short and long option names,
+so that a short name is in effect an abbreviation of a long name.
+
+File +mixed_names.rb+
+defines options that each have both a short and a long name.
+
+  :include: ruby/mixed_names.rb
+
+Executions:
+
+  $ ruby mixed_names.rb --help
+  Usage: mixed_names [options]
+      -x, --xxx                        Short and long, no argument
+      -y, --yyyYYY                     Short and long, required argument
+      -z, --zzz [ZZZ]                  Short and long, optional argument
+  $ ruby mixed_names.rb -x
+  ["--xxx", true]
+  $ ruby mixed_names.rb --xxx
+  ["--xxx", true]
+  $ ruby mixed_names.rb -y
+  mixed_names.rb:12:in `<main>': missing argument: -y (OptionParser::MissingArgument)
+  $ ruby mixed_names.rb -y FOO
+  ["--yyy", "FOO"]
+  $ ruby mixed_names.rb --yyy
+  mixed_names.rb:12:in `<main>': missing argument: --yyy (OptionParser::MissingArgument)
+  $ ruby mixed_names.rb --yyy BAR
+  ["--yyy", "BAR"]
+  $ ruby mixed_names.rb -z
+  ["--zzz", nil]
+  $ ruby mixed_names.rb -z BAZ
+  ["--zzz", "BAZ"]
+  $ ruby mixed_names.rb --zzz
+  ["--zzz", nil]
+  $ ruby mixed_names.rb --zzz BAT
+  ["--zzz", "BAT"]
+
+==== Option Name Abbreviations
+
+By default, abbreviated option names on the command-line are allowed.
+An abbreviated name is valid if it is unique among abbreviated option names.
+
+  :include: ruby/name_abbrev.rb
+
+Executions:

+  $ ruby name_abbrev.rb --dry
+  ["--dry-run", true]
+  $ ruby name_abbrev.rb --dra
+  ["--draft", true]
+
+You can disable abbreviation using method +require_exact+.
+
+  :include: ruby/no_abbreviation.rb
+
+Executions:
+
+  $ ruby no_abbreviation.rb --dry-ru
+  no_abbreviation.rb:10:in `<main>': invalid option: --dry-ru (OptionParser::InvalidOption)
+  $ ruby no_abbreviation.rb --dry-run
+  ["--dry-run", true]
+
+=== Option Arguments
+
+An option may take no argument, a required argument, or an optional argument.
+
+==== Option with No Argument
+
+All the examples above define options with no argument.
+
+==== Option with Required Argument
+
+Specify a required argument for an option by adding a dummy word
+to its name definition.
+
+File +required_argument.rb+ defines two options;
+each has a required argument because the name definition has a following dummy word.
+
+  :include: ruby/required_argument.rb
+
+When an option is found, the given argument is yielded.
+
+Executions:
+
+  $ ruby required_argument.rb --help
+  Usage: required_argument [options]
+      -x, --xxx XXX                    Required argument via short name
+      -y, --y YYY                      Required argument via long name
+  $ ruby required_argument.rb -x AAA
+  ["--xxx", "AAA"]
+  $ ruby required_argument.rb -y BBB
+  ["--yyy", "BBB"]
+
+Omitting a required argument raises an error:
+
+  $ ruby required_argument.rb -x
+  required_argument.rb:9:in `<main>': missing argument: -x (OptionParser::MissingArgument)
+
+==== Option with Optional Argument
+
+Specify an optional argument for an option by adding a dummy word
+enclosed in square brackets to its name definition.
+
+File +optional_argument.rb+ defines two options;
+each has an optional argument because the name definition has a following dummy word
+in square brackets.
+
+  :include: ruby/optional_argument.rb
+
+When an option with an argument is found, the given argument yielded.
+
+Executions:
+
+  $ ruby optional_argument.rb --help
+  Usage: optional_argument [options]
+      -x, --xxx [XXX]                  Optional argument via short  name
+      -y, --yyy [YYY]                  Optional argument via long name
+  $ ruby optional_argument.rb -x AAA
+  ["--xxx", "AAA"]
+  $ ruby optional_argument.rb -y BBB
+  ["--yyy", "BBB"]
+
+Omitting an optional argument does not raise an error.
+
+=== Argument Values
+
+Permissible argument values may be restricted
+either by specifying explicit values
+or by providing a pattern that the given value must match.
+
+==== Explicit Argument Values
+
+You can specify argument values in either of two ways:
+
+- Specify values an array of strings.
+- Specify values a hash.
+
+===== Explicit Values in Array
+
+You can specify explicit argument values in an array of strings.
+The argument value must be one of those strings, or an unambiguous abbreviation.
+
+File +explicit_array_values.rb+ defines options with explicit argument values.
+
+  :include: ruby/explicit_array_values.rb
+
+Executions:
+
+  $ ruby explicit_array_values.rb --help
+  Usage: explicit_array_values [options]
+      -xXXX                            Values for required argument
+      -y [YYY]                         Values for optional argument
+  $ ruby explicit_array_values.rb -x
+  explicit_array_values.rb:9:in `<main>': missing argument: -x (OptionParser::MissingArgument)
+  $ ruby explicit_array_values.rb -x foo
+  ["-x", "foo"]
+  $ ruby explicit_array_values.rb -x f
+  ["-x", "foo"]
+  $ ruby explicit_array_values.rb -x bar
+  ["-x", "bar"]
+  $ ruby explicit_array_values.rb -y ba
+  explicit_array_values.rb:9:in `<main>': ambiguous argument: -y ba (OptionParser::AmbiguousArgument)
+  $ ruby explicit_array_values.rb -x baz
+  explicit_array_values.rb:9:in `<main>': invalid argument: -x baz (OptionParser::InvalidArgument)
+
+
+===== Explicit Values in Hash
+
+You can specify explicit argument values in a hash with string keys.
+The value passed must be one of those keys, or an unambiguous abbreviation;
+the value yielded will be the value for that key.
+
+File +explicit_hash_values.rb+ defines options with explicit argument values.
+
+  :include: ruby/explicit_hash_values.rb
+
+Executions:
+
+  $ ruby explicit_hash_values.rb --help
+  Usage: explicit_hash_values [options]
+      -xXXX                            Values for required argument
+      -y [YYY]                         Values for optional argument
+  $ ruby explicit_hash_values.rb -x
+  explicit_hash_values.rb:9:in `<main>': missing argument: -x (OptionParser::MissingArgument)
+  $ ruby explicit_hash_values.rb -x foo
+  ["-x", 0]
+  $ ruby explicit_hash_values.rb -x f
+  ["-x", 0]
+  $ ruby explicit_hash_values.rb -x bar
+  ["-x", 1]
+  $ ruby explicit_hash_values.rb -x baz
+  explicit_hash_values.rb:9:in `<main>': invalid argument: -x baz (OptionParser::InvalidArgument)
+  $ ruby explicit_hash_values.rb -y
+  ["-y", nil]
+  $ ruby explicit_hash_values.rb -y baz
+  ["-y", 2]
+  $ ruby explicit_hash_values.rb -y bat
+  ["-y", 3]
+  $ ruby explicit_hash_values.rb -y ba
+  explicit_hash_values.rb:9:in `<main>': ambiguous argument: -y ba (OptionParser::AmbiguousArgument)
+  $ ruby explicit_hash_values.rb -y bam
+  ["-y", nil]
+
+==== Argument Value Patterns
+
+You can restrict permissible argument values
+by specifying a Regexp that the given argument must match.
+
+File +matched_values.rb+ defines options with matched argument values.
+
+  :include: ruby/matched_values.rb
+
+Executions:
+
+  $ ruby matched_values.rb --help
+  Usage: matched_values [options]
+          --xxx XXX                    Matched values
+  $ ruby matched_values.rb --xxx foo
+  ["--xxx", "foo"]
+  $ ruby matched_values.rb --xxx FOO
+  ["--xxx", "FOO"]
+  $ ruby matched_values.rb --xxx bar
+  matched_values.rb:6:in `<main>': invalid argument: --xxx bar (OptionParser::InvalidArgument)
+
+=== Keyword Argument +into+
+
+In parsing options, you can add keyword option +into+ with a hash-like argument;
+each parsed option will be added as a name/value pair.
+
+This is useful for:
+
+- Collecting options.
+- Checking for missing options.
+- Providing default values for options.
+
+==== Collecting Options
+
+Use keyword argument +into+ to collect options.
+
+  :include: ruby/collected_options.rb
+
+Executions:
+
+  $ ruby collected_options.rb --help
+  Usage: into [options]
+      -x, --xxx                        Short and long, no argument
+      -y, --yyyYYY                     Short and long, required argument
+      -z, --zzz [ZZZ]                  Short and long, optional argument
+  $ ruby collected_options.rb --xxx
+  {:xxx=>true}
+  $ ruby collected_options.rb --xxx --yyy FOO
+  {:xxx=>true, :yyy=>"FOO"}
+  $ ruby collected_options.rb --xxx --yyy FOO --zzz Bar
+  {:xxx=>true, :yyy=>"FOO", :zzz=>"Bar"}
+  $ ruby collected_options.rb --xxx --yyy FOO --yyy BAR
+  {:xxx=>true, :yyy=>"BAR"}
+
+Note in the last execution that the argument value for option <tt>--yyy</tt>
+was overwritten.
+
+==== Checking for Missing Options
+
+Use the collected options to check for missing options.
+
+  :include: ruby/missing_options.rb
+
+Executions:
+
+  $ ruby missing_options.rb --help
+  Usage: missing_options [options]
+      -x, --xxx                        Short and long, no argument
+      -y, --yyyYYY                     Short and long, required argument
+      -z, --zzz [ZZZ]                  Short and long, optional argument
+  $ ruby missing_options.rb --yyy FOO
+  missing_options.rb:11:in `<main>': Missing required options: [:xxx, :zzz] (RuntimeError)
+
+==== Default Values for Options
+
+Initialize the +into+ argument to define default values for options.
+
+  :include: ruby/default_values.rb
+
+Executions:
+
+  $ ruby default_values.rb --help
+  Usage: default_values [options]
+      -x, --xxx                        Short and long, no argument
+      -y, --yyyYYY                     Short and long, required argument
+      -z, --zzz [ZZZ]                  Short and long, optional argument
+  $ ruby default_values.rb --yyy FOO
+  {:yyy=>"FOO", :zzz=>"BBB"}
+
+=== Argument Converters
+
+An option can specify that its argument is to be converted
+from the default \String to an instance of another class.
+There are a number of built-in converters.
+
+Example: File +date.rb+
+defines an option whose argument is to be converted to a \Date object.
+The argument is converted by method Date#parse.
+
+  :include: ruby/date.rb
+
+Executions:
+
+  $ ruby date.rb --date 2001-02-03
+  [#<Date: 2001-02-03 ((2451944j,0s,0n),+0s,2299161j)>, Date]
+  $ ruby date.rb --date 20010203
+  [#<Date: 2001-02-03 ((2451944j,0s,0n),+0s,2299161j)>, Date]
+  $ ruby date.rb --date "3rd Feb 2001"
+  [#<Date: 2001-02-03 ((2451944j,0s,0n),+0s,2299161j)>, Date]
+
+You can also define custom converters.
+See {Argument Converters}[./argument_converters.rdoc]
+for both built-in and custom converters.
+
+=== Help
+
+\OptionParser makes automatically generated help text available.
+
+The help text consists of:
+
+- A banner, showing the usage.
+- Option short and long names.
+- Option dummy argument names.
+- Option descriptions.
+
+Example code:
+
+  :include: ruby/help.rb
+
+The option names and dummy argument names are defined as described above.
+
+The option description consists of the strings that are not themselves option names;
+An option can have more than one description string.
+Execution:
+
+  Usage: help [options]
+      -x, --xxx                        Adipiscing elit. Aenean commodo ligula eget.
+                                       Aenean massa. Cum sociis natoque penatibus

+                                       nec, pellentesque eu, pretium quis, sem.
+
+The program name is included in the default banner:
+<tt>Usage: #{program_name} [options]</tt>;
+you can change the program name.
+
+  :include: ruby/help_program_name.rb
+
+Execution:
+
+  $ ruby help_program_name.rb --help
+  Usage: help_program_name.rb [options]
+
+You can also change the entire banner.
+
+  :include: ruby/help_banner.rb
+
+Execution:
+
+  $ ruby help_banner.rb --help
+  Usage: ruby help_banner.rb
+
+By default, the option names are indented 4 spaces
+and the width of the option-names field is 32 spaces.
+
+You can change these values, along with the banner,
+by passing parameters to OptionParser.new.
+
+  :include: ruby/help_format.rb
+

+                         nec, pellentesque eu, pretium quis, sem.
+
+=== Top List and Base List
+
+An \OptionParser object maintains a stack of \OptionParser::List objects,
+each of which has a collection of zero or more options.
+It is unlikely that you'll need to add or take away from that stack.
+
+The stack includes:
+
+- The <em>top list</em>, given by \OptionParser#top.
+- The <em>base list</em>, given by \OptionParser#base.
+
+When \OptionParser builds its help text, the options in the top list
+precede those in the base list.
+
+=== Defining Options
+
+Option-defining methods allow you to create an option, and also append/prepend it
+to the top list or append it to the base list.
+
+Each of these next three methods accepts a sequence of parameter arguments and a block,
+creates an option object using method \Option#make_switch (see below),
+and returns the created option:
+
+- \Method \OptionParser#define appends the created option to the top list.
+
+- \Method \OptionParser#define_head prepends the created option to the top list.
+
+- \Method \OptionParser#define_tail appends the created option to the base list.
+
+These next three methods are identical to the three above,
+except for their return values:
+
+- \Method \OptionParser#on is identical to method \OptionParser#define,
+  except that it returns the parser object +self+.
+
+- \Method \OptionParser#on_head is identical to method \OptionParser#define_head,
+  except that it returns the parser object +self+.
+
+- \Method \OptionParser#on_tail is identical to method \OptionParser#define_tail,
+  except that it returns the parser object +self+.
+
+Though you may never need to call it directly,
+here's the core method for defining an option:
+
+- \Method \OptionParser#make_switch accepts an array of parameters and a block.
+  See {Parameters for New Options}[optparse/option_params.rdoc].
+  This method is unlike others here in that it:
+  - Accepts an <em>array of parameters</em>;
+    others accept a <em>sequence of parameter arguments</em>.
+  - Returns an array containing the created option object,
+    option names, and other values;
+    others return either the created option object
+    or the parser object +self+.
+
+=== Parsing
+
+\OptionParser has six instance methods for parsing.
+
+Three have names ending with a "bang" (<tt>!</tt>):
+
+- parse!
+- order!
+- permute!
+
+Each of these methods:
+
+- Accepts an optional array of string arguments +argv+;
+  if not given, +argv+ defaults to the value of OptionParser#default_argv,
+  whose initial value is ARGV.
+- Accepts an optional keyword argument +into+
+  (see {Keyword Argument into}[#label-Keyword+Argument+into]).
+- Returns +argv+, possibly with some elements removed.
+
+The three other methods have names _not_ ending with a "bang":
+
+- parse
+- order
+- permute
+
+Each of these methods:
+
+- Accepts an array of string arguments
+  _or_ zero or more string arguments.
+- Accepts an optional keyword argument +into+ and its value _into_.
+  (see {Keyword Argument into}[#label-Keyword+Argument+into]).
+- Returns +argv+, possibly with some elements removed.
+
+==== \Method parse!
+
+\Method parse!:
+
+- Accepts an optional array of string arguments +argv+;
+  if not given, +argv+ defaults to the value of OptionParser#default_argv,
+  whose initial value is ARGV.
+- Accepts an optional keyword argument +into+
+  (see {Keyword Argument into}[#label-Keyword+Argument+into]).
+- Returns +argv+, possibly with some elements removed.
+
+The method processes the elements in +argv+ beginning at <tt>argv[0]</tt>,
+and ending, by default, at the end.
+
+Otherwise processing ends and the method returns when:
+
+- The terminator argument <tt>--</tt> is found;
+  the terminator argument is removed before the return.
+- Environment variable +POSIXLY_CORRECT+ is defined
+  and a non-option argument is found;
+  the non-option argument is not removed.
+  Note that the _value_ of that variable does not matter,
+  as only its existence is checked.

+\Method parse:
+
+- Accepts an array of string arguments
+  _or_ zero or more string arguments.
+- Accepts an optional keyword argument +into+ and its value _into_.
+  (see {Keyword Argument into}[#label-Keyword+Argument+into]).
+- Returns +argv+, possibly with some elements removed.
+
+If given an array +ary+, the method forms array +argv+ as <tt>ary.dup</tt>.
+If given zero or more string arguments, those arguments are formed
+into array +argv+.
+
+The method calls
+
+  parse!(argv, into: into)
+
+Note that environment variable +POSIXLY_CORRECT+
+and the terminator argument <tt>--</tt> are honored.

+== Packed \Data
+
+Certain Ruby core methods deal with packing and unpacking data:
+
+- \Method Array#pack:
+  Formats each element in array +self+ into a binary string;
+  returns that string.
+- \Method String#unpack:
+  Extracts data from string +self+,
+  forming objects that become the elements of a new array;
+  returns that array.
+- \Method String#unpack1:
+  Does the same, but unpacks and returns only the first extracted object.
+
+Each of these methods accepts a string +template+,
+consisting of zero or more _directive_ characters,
+each followed by zero or more _modifier_ characters.
+
+Examples (directive <tt>'C'</tt> specifies 'unsigned character'):
+
+  [65].pack('C')      # => "A"  # One element, one directive.
+  [65, 66].pack('CC') # => "AB" # Two elements, two directives.
+  [65, 66].pack('C')  # => "A"  # Extra element is ignored.
+  [65].pack('')       # => ""   # No directives.
+  [65].pack('CC')               # Extra directive raises ArgumentError.
+
+  'A'.unpack('C')   # => [65]      # One character, one directive.
+  'AB'.unpack('CC') # => [65, 66]  # Two characters, two directives.
+  'AB'.unpack('C')  # => [65]      # Extra character is ignored.
+  'A'.unpack('CC')  # => [65, nil] # Extra directive generates nil.
+  'AB'.unpack('')   # => []        # No directives.
+
+The string +template+ may contain any mixture of valid directives
+(directive <tt>'c'</tt> specifies 'signed character'):
+
+  [65, -1].pack('cC')  # => "A\xFF"
+  "A\xFF".unpack('cC') # => [65, 255]
+
+The string +template+ may contain whitespace (which is ignored)
+and comments, each of which begins with character <tt>'#'</tt>
+and continues up to and including the next following newline:
+
+  [0,1].pack("  C  #foo \n  C  ")    # => "\x00\x01"
+  "\0\1".unpack("  C  #foo \n  C  ") # => [0, 1]
+
+Any directive may be followed by either of these modifiers:
+
+- <tt>'*'</tt> - The directive is to be applied as many times as needed:
+
+    [65, 66].pack('C*') # => "AB"
+    'AB'.unpack('C*')   # => [65, 66]
+
+- Integer +count+ - The directive is to be applied +count+ times:
+
+    [65, 66].pack('C2') # => "AB"
+    [65, 66].pack('C3') # Raises ArgumentError.
+    'AB'.unpack('C2')   # => [65, 66]
+    'AB'.unpack('C3')   # => [65, 66, nil]
+
+  Note: Directives in <tt>%w[A a Z m]</tt> use +count+ differently;
+  see {String Directives}[rdoc-ref:packed_data.rdoc@String+Directives].
+
+If elements don't fit the provided directive, only least significant bits are encoded:
+
+    [257].pack("C").unpack("C") # => [1]
+
+=== Packing \Method
+
+\Method Array#pack accepts optional keyword argument
++buffer+ that specifies the target string (instead of a new string):
+
+  [65, 66].pack('C*', buffer: 'foo') # => "fooAB"
+
+The method can accept a block:
+
+  # Packed string is passed to the block.
+  [65, 66].pack('C*') {|s| p s }    # => "AB"
+
+=== Unpacking Methods
+
+Methods String#unpack and String#unpack1 each accept
+an optional keyword argument +offset+ that specifies an offset
+into the string:
+
+  'ABC'.unpack('C*', offset: 1)  # => [66, 67]
+  'ABC'.unpack1('C*', offset: 1) # => 66
+
+Both methods can accept a block:
+
+  # Each unpacked object is passed to the block.
+  ret = []
+  "ABCD".unpack("C*") {|c| ret << c }
+  ret # => [65, 66, 67, 68]
+
+  # The single unpacked object is passed to the block.
+  'AB'.unpack1('C*') {|ele| p ele } # => 65
+
+=== \Integer Directives
+
+Each integer directive specifies the packing or unpacking
+for one element in the input or output array.

+
+  追加されるメソッドの使い方は次の通りです．
+
+   IO#expect(pattern,timeout=9999999)
+
+pattern は String か Regexp のインスタンス，timeout は Fixnum
+のインスタンスです．timeout は省略できます．
+  このメソッドがブロックなしで呼ばれた場合，まずレシーバである
+IOオブジェクトから pattern にマッチするパターンが読みこまれる
+まで待ちます．パターンが得られたら，そのパターンに関する配列を
+返します．配列の最初の要素は，pattern にマッチするまでに読みこ
+まれた内容の文字列です．2番目以降の要素は，pattern の正規表現
+の中にアンカーがあった場合に，そのアンカーにマッチする部分です．
+もしタイムアウトが起きた場合は，このメソッドはnilを返します．
+  このメソッドがブロック付きで呼ばれた場合には，マッチした要素の
+配列がブロック引数として渡され，ブロックが評価されます．

+# Ractor - Ruby's Actor-like concurrent abstraction
+
+Ractor is designed to provide a parallel execution feature of Ruby without thread-safety concerns.
+
+## Summary
+
+### Multiple Ractors in an interpreter process
+
+You can make multiple Ractors and they run in parallel.
+
+* `Ractor.new{ expr }` creates a new Ractor and `expr` is run in parallel on a parallel computer.
+* Interpreter invokes with the first Ractor (called *main Ractor*).
+* If main Ractor terminated, all Ractors receive terminate request like Threads (if main thread (first invoked Thread), Ruby interpreter sends all running threads to terminate execution).
+* Each Ractor has 1 or more Threads.
+  * Threads in a Ractor shares a Ractor-wide global lock like GIL (GVL in MRI terminology), so they can't run in parallel (without releasing GVL explicitly in C-level). Threads in different ractors run in parallel.
+  * The overhead of creating a Ractor is similar to overhead of one Thread creation.
+
+### Limited sharing between multiple ractors
+
+Ractors don't share everything, unlike threads.
+
+* Most objects are *Unshareable objects*, so you don't need to care about thread-safety problems which are caused by sharing.
+* Some objects are *Shareable objects*.
+  * Immutable objects: frozen objects which don't refer to unshareable-objects.
+    * `i = 123`: `i` is an immutable object.
+    * `s = "str".freeze`: `s` is an immutable object.
+    * `a = [1, [2], 3].freeze`: `a` is not an immutable object because `a` refers unshareable-object `[2]` (which is not frozen).
+    * `h = {c: Object}.freeze`: `h` is an immutable object because `h` refers Symbol `:c` and shareable `Object` class object which is not frozen.
+  * Class/Module objects
+  * Special shareable objects
+    * Ractor object itself.
+    * And more...
+
+### Two-types communication between Ractors
+
+Ractors communicate with each other and synchronize the execution by message exchanging between Ractors. There are two message exchange protocols: push type (message passing) and pull type.
+
+* Push type message passing: `Ractor#send(obj)` and `Ractor.receive()` pair.
+  * Sender ractor passes the `obj` to the ractor `r` by `r.send(obj)` and receiver ractor receives the message with `Ractor.receive`.
+  * Sender knows the destination Ractor `r` and the receiver does not know the sender (accept all messages from any ractors).
+  * Receiver has infinite queue and sender enqueues the message. Sender doesn't block to put message into this queue.
+  * This type of message exchanging is employed by many other Actor-based languages.
+  * `Ractor.receive_if{ filter_expr }` is a variant of `Ractor.receive` to select a message.
+* Pull type communication: `Ractor.yield(obj)` and `Ractor#take()` pair.
+  * Sender ractor declare to yield the `obj` by `Ractor.yield(obj)` and receiver Ractor take it with `r.take`.
+  * Sender doesn't know a destination Ractor and receiver knows the sender Ractor `r`.
+  * Sender or receiver will block if there is no other side.
+
+### Copy & Move semantics to send messages
+
+To send unshareable objects as messages, objects are copied or moved.
+
+* Copy: use deep-copy.
+* Move: move membership.
+  * Sender can not access the moved object after moving the object.
+  * Guarantee that at least only 1 Ractor can access the object.
+
+### Thread-safety
+
+Ractor helps to write a thread-safe concurrent program, but we can make thread-unsafe programs with Ractors.
+
+* GOOD: Sharing limitation
+  * Most objects are unshareable, so we can't make data-racy and race-conditional programs.
+  * Shareable objects are protected by an interpreter or locking mechanism.
+* BAD: Class/Module can violate this assumption
+  * To make it compatible with old behavior, classes and modules can introduce data-race and so on.
+  * Ruby programmers should take care if they modify class/module objects on multi Ractor programs.
+* BAD: Ractor can't solve all thread-safety problems
+  * There are several blocking operations (waiting send, waiting yield and waiting take) so you can make a program which has dead-lock and live-lock issues.
+  * Some kind of shareable objects can introduce transactions (STM, for example). However, misusing transactions will generate inconsistent state.
+
+Without Ractor, we need to trace all state-mutations to debug thread-safety issues.
+With Ractor, you can concentrate on suspicious code which are shared with Ractors.
+
+## Creation and termination
+
+### `Ractor.new`
+
+* `Ractor.new{ expr }` generates another Ractor.
+
+```ruby
+# Ractor.new with a block creates new Ractor
+r = Ractor.new do
+  # This block will be run in parallel with other ractors
+end
+
+# You can name a Ractor with `name:` argument.
+r = Ractor.new name: 'test-name' do
+end
+
+# and Ractor#name returns its name.
+r.name #=> 'test-name'
+```
+
+### Given block isolation
+
+The Ractor executes given `expr` in a given block.
+Given block will be isolated from outer scope by the `Proc#isolate` method (not exposed yet for Ruby users). To prevent sharing unshareable objects between ractors, block outer-variables, `self` and other information are isolated.
+
+`Proc#isolate` is called at Ractor creation time (when `Ractor.new` is called). If given Proc object is not able to isolate because of outer variables and so on, an error will be raised.
+
+```ruby
+begin
+  a = true
+  r = Ractor.new do
+    a #=> ArgumentError because this block accesses `a`.
+  end
+  r.take # see later
+rescue ArgumentError
+end
+```
+
+* The `self` of the given block is the `Ractor` object itself.
+
+```ruby
+r = Ractor.new do
+  p self.class #=> Ractor
+  self.object_id
+end
+r.take == self.object_id #=> false
+```
+
+Passed arguments to `Ractor.new()` becomes block parameters for the given block. However, an interpreter does not pass the parameter object references, but send them as messages (see below for details).
+
+```ruby
+r = Ractor.new 'ok' do |msg|
+  msg #=> 'ok'
+end
+r.take #=> 'ok'
+```
+
+```ruby
+# almost similar to the last example
+r = Ractor.new do
+  msg = Ractor.receive
+  msg
+end
+r.send 'ok'
+r.take #=> 'ok'
+```
+
+### An execution result of given block
+
+Return value of the given block becomes an outgoing message (see below for details).
+
+```ruby
+r = Ractor.new do
+  'ok'
+end
+r.take #=> `ok`
+```
+
+```ruby
+# almost similar to the last example
+r = Ractor.new do
+  Ractor.yield 'ok'
+end
+r.take #=> 'ok'
+```
+
+Error in the given block will be propagated to the receiver of an outgoing message.
+
+```ruby
+r = Ractor.new do
+  raise 'ok' # exception will be transferred to the receiver
+end
+
+begin
+  r.take
+rescue Ractor::RemoteError => e
+  e.cause.class   #=> RuntimeError
+  e.cause.message #=> 'ok'
+  e.ractor        #=> r
+end
+```
+
+## Communication between Ractors
+
+Communication between Ractors is achieved by sending and receiving messages. There are two ways to communicate with each other.
+
+* (1) Message sending/receiving
+  * (1-1) push type send/receive (sender knows receiver). Similar to the Actor model.
+  * (1-2) pull type yield/take (receiver knows sender).
+* (2) Using shareable container objects
+  * Ractor::TVar gem ([ko1/ractor-tvar](https://github.com/ko1/ractor-tvar))
+  * more?
+
+Users can control program execution timing with (1), but should not control with (2) (only manage as critical section).
+
+For message sending and receiving, there are two types of APIs: push type and pull type.
+
+* (1-1) send/receive (push type)
+  * `Ractor#send(obj)` (`Ractor#<<(obj)` is an alias) send a message to the Ractor's incoming port. Incoming port is connected to the infinite size incoming queue so `Ractor#send` will never block.
+  * `Ractor.receive` dequeue a message from its own incoming queue. If the incoming queue is empty, `Ractor.receive` calling will block.
+  * `Ractor.receive_if{|msg| filter_expr }` is variant of `Ractor.receive`. `receive_if` only receives a message which `filter_expr` is true (So `Ractor.receive` is the same as `Ractor.receive_if{ true }`.
+* (1-2) yield/take (pull type)
+  * `Ractor.yield(obj)` send an message to a Ractor which are calling `Ractor#take` via outgoing port . If no Ractors are waiting for it, the `Ractor.yield(obj)` will block. If multiple Ractors are waiting for `Ractor.yield(obj)`, only one Ractor can receive the message.
+  * `Ractor#take` receives a message which is waiting by `Ractor.yield(obj)` method from the specified Ractor. If the Ractor does not call `Ractor.yield` yet, the `Ractor#take` call will block.
+* `Ractor.select()` can wait for the success of `take`, `yield` and `receive`.
+* You can close the incoming port or outgoing port.
+  * You can close then with `Ractor#close_incoming` and `Ractor#close_outgoing`.
+  * If the incoming port is closed for a Ractor, you can't `send` to the Ractor. If `Ractor.receive` is blocked for the closed incoming port, then it will raise an exception.
+  * If the outgoing port is closed for a Ractor, you can't call `Ractor#take` and `Ractor.yield` on the Ractor. If ractors are blocking by `Ractor#take` or `Ractor.yield`, closing outgoing port will raise an exception on these blocking ractors.
+  * When a Ractor is terminated, the Ractor's ports are closed.
+* There are 3 ways to send an object as a message
+  * (1) Send a reference: Sending a shareable object, send only a reference to the object (fast)
+  * (2) Copy an object: Sending an unshareable object by copying an object deeply (slow). Note that you can not send an object which does not support deep copy. Some `T_DATA` objects are not supported.
+  * (3) Move an object: Sending an unshareable object reference with a membership. Sender Ractor can not access moved objects anymore (raise an exception) after moving it. Current implementation makes new object as a moved object for receiver Ractor and copies references of sending object to moved object.
+  * You can choose "Copy" and "Move" by the `move:` keyword, `Ractor#send(obj, move: true/false)` and `Ractor.yield(obj, move: true/false)` (default is `false` (COPY)).
+
+### Sending/Receiving ports
+
+Each Ractor has _incoming-port_ and _outgoing-port_. Incoming-port is connected to the infinite sized incoming queue.

+                 +-------------------------------------------+
+
+

+  +----+     +----+
+  * r1 |---->* r2 *
+  +----+     +----+
+

+Connection example: Ractor.yield(obj) on r1, r1.take on r2

+
+  +----+

+  * r2 *------|
+  +----+
+```
+
+```ruby
+r = Ractor.new do
+  msg = Ractor.receive # Receive from r's incoming queue
+  msg # send back msg as block return value
+end
+r.send 'ok' # Send 'ok' to r's incoming port -> incoming queue
+r.take      # Receive from r's outgoing port
+```
+
+The last example shows the following ractor network.
+
+```
+
+  +------+        +---+
+  * main |------> * r *---+
+  +------+        +---+   |
+      ^                   |
+      +-------------------+
+```
+
+And this code can be simplified by using an argument for `Ractor.new`.
+
+```ruby
+# Actual argument 'ok' for `Ractor.new()` will be sent to created Ractor.
+r = Ractor.new 'ok' do |msg|
+  # Values for formal parameters will be received from incoming queue.
+  # Similar to: msg = Ractor.receive
+
+  msg # Return value of the given block will be sent via outgoing port
+end
+
+# receive from the r's outgoing port.
+r.take #=> `ok`
+```
+
+### Return value of a block for `Ractor.new`
+
+As already explained, the return value of `Ractor.new` (an evaluated value of `expr` in `Ractor.new{ expr }`) can be taken by `Ractor#take`.
+
+```ruby
+Ractor.new{ 42 }.take #=> 42
+```
+
+When the block return value is available, the Ractor is dead so that no ractors except taken Ractor can touch the return value, so any values can be sent with this communication path without any modification.
+
+```ruby
+r = Ractor.new do
+  a = "hello"
+  binding
+end
+
+r.take.eval("p a") #=> "hello" (other communication path can not send a Binding object directly)
+```
+
+### Wait for multiple Ractors with `Ractor.select`
+
+You can wait multiple Ractor's `yield` with `Ractor.select(*ractors)`.
+The return value of `Ractor.select()` is `[r, msg]` where `r` is yielding Ractor and `msg` is yielded message.
+
+Wait for a single ractor (same as `Ractor.take`):
+
+```ruby
+r1 = Ractor.new{'r1'}
+
+r, obj = Ractor.select(r1)
+r == r1 and obj == 'r1' #=> true
+```
+
+Wait for two ractors:
+
+```ruby
+r1 = Ractor.new{'r1'}
+r2 = Ractor.new{'r2'}
+rs = [r1, r2]
+as = []
+
+# Wait for r1 or r2's Ractor.yield
+r, obj = Ractor.select(*rs)
+rs.delete(r)
+as << obj
+
+# Second try (rs only contain not-closed ractors)
+r, obj = Ractor.select(*rs)
+rs.delete(r)
+as << obj
+as.sort == ['r1', 'r2'] #=> true
+```
+
+Complex example:
+
+```ruby
+pipe = Ractor.new do
+  loop do
+    Ractor.yield Ractor.receive
+  end
+end
+
+RN = 10
+rs = RN.times.map{|i|
+  Ractor.new pipe, i do |pipe, i|
+    msg = pipe.take
+    msg # ping-pong
+  end
+}
+RN.times{|i|
+  pipe << i
+}
+RN.times.map{
+  r, n = Ractor.select(*rs)
+  rs.delete r
+  n
+}.sort #=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
+```
+
+Multiple Ractors can send to one Ractor.
+
+```ruby
+# Create 10 ractors and they send objects to pipe ractor.
+# pipe ractor yield received objects
+
+pipe = Ractor.new do
+  loop do
+    Ractor.yield Ractor.receive
+  end
+end
+
+RN = 10
+rs = RN.times.map{|i|
+  Ractor.new pipe, i do |pipe, i|
+    pipe << i
+  end
+}
+
+RN.times.map{
+  pipe.take
+}.sort #=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
+```
+
+TODO: Current `Ractor.select()` has the same issue of `select(2)`, so this interface should be refined.
+
+TODO: `select` syntax of go-language uses round-robin technique to make fair scheduling. Now `Ractor.select()` doesn't use it.
+
+### Closing Ractor's ports
+
+* `Ractor#close_incoming/outgoing` close incoming/outgoing ports (similar to `Queue#close`).
+* `Ractor#close_incoming`
+  * `r.send(obj) ` where `r`'s incoming port is closed, will raise an exception.
+  * When the incoming queue is empty and incoming port is closed, `Ractor.receive` raises an exception. If the incoming queue is not empty, it dequeues an object without exceptions.
+* `Ractor#close_outgoing`
+  * `Ractor.yield` on a Ractor which closed the outgoing port, it will raise an exception.
+  * `Ractor#take` for a Ractor which closed the outgoing port, it will raise an exception. If `Ractor#take` is blocking, it will raise an exception.
+* When a Ractor terminates, the ports are closed automatically.
+  * Return value of the Ractor's block will be yielded as `Ractor.yield(ret_val)`, even if the implementation terminates the based native thread.
+
+Example (try to take from closed Ractor):
+
+```ruby
+r = Ractor.new do
+  'finish'
+end
+r.take # success (will return 'finish')
+begin
+  o = r.take # try to take from closed Ractor
+rescue Ractor::ClosedError
+  'ok'
+else
+  "ng: #{o}"
+end
+```
+
+Example (try to send to closed (terminated) Ractor):
+
+```ruby
+r = Ractor.new do
+end
+
+r.take # wait terminate
+
+begin
+  r.send(1)
+rescue Ractor::ClosedError
+  'ok'
+else
+  'ng'
+end
+```
+
+When multiple Ractors are waiting for `Ractor.yield()`, `Ractor#close_outgoing` will cancel all blocking by raising an exception (`ClosedError`).
+
+### Send a message by copying
+
+`Ractor#send(obj)` or `Ractor.yield(obj)` copy `obj` deeply if `obj` is an unshareable object.
+
+```ruby
+obj = 'str'.dup
+r = Ractor.new obj do |msg|
+  # return received msg's object_id
+  msg.object_id
+end
+
+obj.object_id == r.take #=> false
+```
+
+Some objects are not supported to copy the value, and raise an exception.
+
+```ruby
+obj = Thread.new{}
+begin
+  Ractor.new obj do |msg|
+    msg
+  end
+rescue TypeError => e
+  e.message #=> #<TypeError: allocator undefined for Thread>
+else
+  'ng' # unreachable here
+end
+```
+
+### Send a message by moving
+
+`Ractor#send(obj, move: true)` or `Ractor.yield(obj, move: true)` move `obj` to the destination Ractor.
+If the source Ractor touches the moved object (for example, call the method like `obj.foo()`), it will be an error.
+
+```ruby
+# move with Ractor#send
+r = Ractor.new do
+  obj = Ractor.receive
+  obj << ' world'
+end
+
+str = 'hello'
+r.send str, move: true
+modified = r.take #=> 'hello world'
+
+# str is moved, and accessing str from this Ractor is prohibited
+
+begin
+  # Error because it touches moved str.
+  str << ' exception' # raise Ractor::MovedError
+rescue Ractor::MovedError
+  modified #=> 'hello world'
+else
+  raise 'unreachable'
+end
+```
+
+```ruby
+# move with Ractor.yield
+r = Ractor.new do
+  obj = 'hello'
+  Ractor.yield obj, move: true
+  obj << 'world'  # raise Ractor::MovedError
+end
+
+str = r.take
+begin
+  r.take
+rescue Ractor::RemoteError
+  p str #=> "hello"
+end
+```
+
+Some objects are not supported to move, and an exception will be raised.
+
+```ruby
+r = Ractor.new do
+  Ractor.receive
+end
+
+r.send(Thread.new{}, move: true) #=> allocator undefined for Thread (TypeError)
+```
+
+To achieve the access prohibition for moved objects, _class replacement_ technique is used to implement it.
+
+### Shareable objects
+
+The following objects are shareable.
+
+* Immutable objects
+  * Small integers, some symbols, `true`, `false`, `nil` (a.k.a. `SPECIAL_CONST_P()` objects in internal)
+  * Frozen native objects
+    * Numeric objects: `Float`, `Complex`, `Rational`, big integers (`T_BIGNUM` in internal)
+    * All Symbols.
+  * Frozen `String` and `Regexp` objects (their instance variables should refer only shareable objects)
+* Class, Module objects (`T_CLASS`, `T_MODULE` and `T_ICLASS` in internal)
+* `Ractor` and other special objects which care about synchronization.
+
+Implementation: Now shareable objects (`RVALUE`) have `FL_SHAREABLE` flag. This flag can be added lazily.
+
+To make shareable objects, `Ractor.make_shareable(obj)` method is provided. In this case, try to make sharaeble by freezing `obj` and recursively travasible objects. This method accepts `copy:` keyword (default value is false).`Ractor.make_shareable(obj, copy: true)` tries to make a deep copy of `obj` and make the copied object shareable.
+
+## Language changes to isolate unshareable objects between Ractors
+
+To isolate unshareable objects between Ractors, we introduced additional language semantics on multi-Ractor Ruby programs.
+
+Note that without using Ractors, these additional semantics is not needed (100% compatible with Ruby 2).
+
+### Global variables
+
+Only the main Ractor (a Ractor created at starting of interpreter) can access global variables.
+
+```ruby
+$gv = 1
+r = Ractor.new do
+  $gv
+end
+
+begin
+  r.take
+rescue Ractor::RemoteError => e
+  e.cause.message #=> 'can not access global variables from non-main Ractors'
+end
+```
+
+Note that some special global variables are ractor-local, like `$stdin`, `$stdout`, `$stderr`. See [[Bug #17268]](https://bugs.ruby-lang.org/issues/17268) for more details.
+
+### Instance variables of shareable objects
+
+Instance variables of classes/modules can be get from non-main Ractors if the referring values are shareable objects.
+
+```ruby
+class C
+  @iv = 1
+end
+
+p Ractor.new do
+  class C
+     @iv
+  end
+end.take #=> 1
+```
+
+Otherwise, only the main Ractor can access instance variables of shareable objects.
+
+```ruby
+class C
+  @iv = [] # unshareable object
+end
+
+Ractor.new do
+  class C
+    begin
+      p @iv
+    rescue Ractor::IsolationError
+      p $!.message
+      #=> "can not get unshareable values from instance variables of classes/modules from non-main Ractors"
+    end
+
+    begin
+      @iv = 42
+    rescue Ractor::IsolationError
+      p $!.message
+      #=> "can not set instance variables of classes/modules by non-main Ractors"
+    end
+  end
+end.take
+```
+
+
+
+```ruby
+shared = Ractor.new{}
+shared.instance_variable_set(:@iv, 'str')
+
+r = Ractor.new shared do |shared|
+  p shared.instance_variable_get(:@iv)
+end
+
+begin
+  r.take
+rescue Ractor::RemoteError => e
+  e.cause.message #=> can not access instance variables of shareable objects from non-main Ractors (Ractor::IsolationError)
+end
+```
+
+Note that instance variables for class/module objects are also prohibited on Ractors.
+
+### Class variables
+
+Only the main Ractor can access class variables.
+
+```ruby
+class C
+  @@cv = 'str'
+end
+
+r = Ractor.new do
+  class C
+    p @@cv
+  end
+end
+
+
+begin
+  r.take
+rescue => e
+  e.class #=> Ractor::IsolationError
+end
+```
+
+### Constants
+
+Only the main Ractor can read constants which refer to the unshareable object.
+
+```ruby
+class C
+  CONST = 'str'
+end
+r = Ractor.new do
+  C::CONST
+end
+begin
+  r.take
+rescue => e
+  e.class #=> Ractor::IsolationError
+end
+```
+
+Only the main Ractor can define constants which refer to the unshareable object.
+
+```ruby
+class C
+end
+r = Ractor.new do
+  C::CONST = 'str'
+end
+begin
+  r.take
+rescue => e
+  e.class #=> Ractor::IsolationError
+end
+```
+
+To make multi-ractor supported library, the constants should only refer shareable objects.
+
+```ruby
+TABLE = {a: 'ko1', b: 'ko2', c: 'ko3'}
+```
+
+In this case, `TABLE` references an unshareable Hash object. So that other ractors can not refer `TABLE` constant. To make it shareable, we can use `Ractor.make_shareable()` like that.
+
+```ruby
+TABLE = Ractor.make_shareable( {a: 'ko1', b: 'ko2', c: 'ko3'} )
+```
+
+To make it easy, Ruby 3.0 introduced new `shareable_constant_value` Directive.
+
+```ruby
+# shareable_constant_value: literal
+
+TABLE = {a: 'ko1', b: 'ko2', c: 'ko3'}
+#=> Same as: TABLE = Ractor.make_shareable( {a: 'ko1', b: 'ko2', c: 'ko3'} )
+```
+
+`shareable_constant_value` directive accepts the following modes (descriptions use the example: `CONST = expr`):
+
+* none: Do nothing. Same as: `CONST = expr`
+* literal:
+  * if `expr` is consites of literals, replaced to `CONST = Ractor.make_shareable(expr)`.
+  * otherwise: replaced to `CONST = expr.tap{|o| raise unless Ractor.shareable?}`.
+* experimental_everything: replaced to `CONST = Ractor.make_shareable(expr)`.
+* experimental_copy: replaced to `CONST = Ractor.make_shareable(expr, copy: true)`.
+
+Except the `none` mode (default), it is guaranteed that the assigned constants refer to only shareable objects.
+
+See [doc/syntax/comments.rdoc](syntax/comments.rdoc) for more details.
+
+## Implementation note
+
+* Each Ractor has its own thread, it means each Ractor has at least 1 native thread.
+* Each Ractor has its own ID (`rb_ractor_t::pub::id`).
+  * On debug mode, all unshareable objects are labeled with current Ractor's id, and it is checked to detect unshareable object leak (access an object from different Ractor) in VM.
+
+## Examples

+### Traditional Ring example in Actor-model
+
+```ruby
+RN = 1_000
+CR = Ractor.current

+r = Ractor.new do
+  p Ractor.receive
+  CR << :fin

+
+RN.times{
+  r = Ractor.new r do |next_r|
+    next_r << Ractor.receive

+}
+
+p :setup_ok
+r << 1
+p Ractor.receive
+```

+def fib n
+  if n < 2
+    1
+  else
+    fib(n-2) + fib(n-1)
+  end
+end
+
+RN = 10
+rs = (1..RN).map do |i|
+  Ractor.new i do |i|

+
+until rs.empty?
+  r, v = Ractor.select(*rs)
+  rs.delete r

+# \Class \RDoc::MarkupReference exists only to provide a suitable home
+# for a reference document for \RDoc markup.
+#
+# All objects defined in this class -- classes, modules, methods, aliases,
+# attributes, and constants -- are solely for illustrating \RDoc markup,
+# and have no other legitimate use.
+#
+# = \RDoc Markup Reference
+#
+# Notes:
+#
+# - Examples in this reference are Ruby code and comments;
+#   certain differences from other sources
+#   (such as C code and comments) are noted.
+# - An example that shows rendered HTML output
+#   displays that output in a blockquote:
+#
+#   Rendered HTML:
+#   >>>
+#     Some stuff
+#
+# \RDoc-generated documentation is derived from and controlled by:
+#
+# - Single-line or multi-line comments that precede certain definitions;
+#   see {Markup in Comments}[rdoc-ref:RDoc::MarkupReference@Markup+in+Comments].
+# - \RDoc directives in trailing comments (on the same line as code);
+#   see <tt>:nodoc:</tt>, <tt>:doc:</tt>, and <tt>:notnew</tt>.
+# - \RDoc directives in single-line comments;
+#   see other {Directives}[rdoc-ref:RDoc::MarkupReference@Directives].
+# - The Ruby code itself (but not from C code);
+#   see {Documentation Derived from Ruby Code}[rdoc-ref:RDoc::MarkupReference@Documentation+Derived+from+Ruby+Code].
+#
+# == Markup in Comments
+#
+# The treatment of markup in comments varies according to the type of file:
+#
+# - <tt>.rb</tt> (Ruby code file): markup is parsed from Ruby comments.
+# - <tt>.c</tt> (C code file): markup is parsed from C comments.
+# - <tt>.rdoc</tt> (RDoc text file): markup is parsed from the entire file.
+#
+# The comment associated with
+# a Ruby class, module, method, alias, constant, or attribute
+# becomes the documentation for that defined object:
+#
+# - In a Ruby file, that comment immediately precedes
+#   the definition of the object.
+# - In a C file, that comment immediately precedes
+#   the function that implements a method,
+#   or otherwise immediately precedes the definition of the object.
+#
+# In either a Ruby or a C file,
+# \RDoc ignores comments that do not precede object definitions.
+#
+# In an \RDoc file, the text is not associated with any code object,
+# but may (depending on how the documentation is built),
+# become a separate page.
+#
+# Almost all examples on this page are all RDoc-like;
+# that is, they have no comment markers like Ruby <tt>#</tt>
+# or C <tt>/* ... */</tt>.
+#
+# === Margins
+#
+# In a multi-line comment,
+# \RDoc looks for the comment's natural left margin,
+# which becomes the <em>base margin</em> for the comment
+# and is the initial <em>current margin</em> for for the comment.
+#
+# The current margin can change, and does so, for example in a list.
+#
+# === Blocks
+#
+# It's convenient to think of \RDoc markup input as a sequence of _blocks_
+# of various types (details at the links):
+#
+# - {Paragraph}[rdoc-ref:RDoc::MarkupReference@Paragraphs]:
+#   an ordinary paragraph.
+# - {Verbatim text block}[rdoc-ref:RDoc::MarkupReference@Verbatim+Text+Blocks]:
+#   a block of text to be rendered literally.
+# - {Code block}[rdoc-ref:RDoc::MarkupReference@Code+Blocks]:
+#   a verbatim text block containing Ruby code,
+#   to be rendered with code highlighting.
+# - {Block quote}[rdoc-ref:RDoc::MarkupReference@Block+Quotes]:
+#   a longish quoted passage, to be rendered with indentation
+#   instead of quote marks.
+# - {List}[rdoc-ref:RDoc::MarkupReference@Lists]: items for
+#   a bullet list, numbered list, lettered list, or labeled list.
+# - {Heading}[rdoc-ref:RDoc::MarkupReference@Headings]:
+#   a section heading.
+# - {Horizontal rule}[rdoc-ref:RDoc::MarkupReference@Horizontal+Rules]:
+#   a line across the rendered page.
+# - {Directive}[rdoc-ref:RDoc::MarkupReference@Directives]:
+#   various special directions for the rendering.
+# - {Text Markup}[rdoc-ref:RDoc:MarkupReference@Text+Markup]:
+#   text to be rendered in a special way.
+#
+# About the blocks:
+#
+# - Except for a paragraph, a block is distinguished by its indentation,
+#   or by unusual initial or embedded characters.
+# - Any block may appear independently
+#   (that is, not nested in another block);
+#   some blocks may be nested, as detailed below.
+#
+# ==== Paragraphs
+#
+# A paragraph consists of one or more non-empty lines of ordinary text,
+# each beginning at the current margin.
+#
+# Note: Here, <em>ordinary text</em> means text that is <em>not identified</em>
+# by indentation, or by unusual initial or embedded characters.
+# See below.
+#
+# Paragraphs are separated by one or more empty lines.
+#
+# Example input:
+#
+#   \RDoc produces HTML and command-line documentation for Ruby projects.
+#   \RDoc includes the rdoc and ri tools for generating and displaying
+#   documentation from the command-line.
+#
+#   You'll love it.
+#
+# Rendered HTML:
+# >>>
+#   \RDoc produces HTML and command-line documentation for Ruby projects.
+#   \RDoc includes the rdoc and ri tools for generating and displaying
+#   documentation from the command-line.
+#
+#   You'll love it.
+#
+# A paragraph may contain nested blocks, including:
+#
+# - {Verbatim text blocks}[rdoc-ref:RDoc::MarkupReference@Verbatim+Text+Blocks].
+# - {Code blocks}[rdoc-ref:RDoc::MarkupReference@Code+Blocks].
+# - {Block quotes}[rdoc-ref:RDoc::MarkupReference@Block+Quotes].
+# - {Lists}[rdoc-ref:RDoc::MarkupReference@Lists].
+# - {Headings}[rdoc-ref:RDoc::MarkupReference@Headings].
+# - {Horizontal rules}[rdoc-ref:RDoc::MarkupReference@Horizontal+Rules].
+# - {Text Markup}[rdoc-ref:RDoc:MarkupReference@Text+Markup].
+#
+# ==== Verbatim Text Blocks
+#
+# Text indented farther than the current margin becomes a <em>verbatim text block</em>
+# (or a code block, described next).
+# In the rendered HTML, such text:
+#
+# - Is indented.
+# - Has a contrasting background color.
+#
+# The verbatim text block ends at the first line beginning at the current margin.
+#
+# Example input:
+#
+#   This is not verbatim text.
+#
+#     This is verbatim text.
+#       Whitespace is honored.     # See?
+#         Whitespace is honored.     # See?
+#
+#     This is still the same verbatim text block.
+#
+#   This is not verbatim text.
+#
+# Rendered HTML:
+# >>>
+#   This is not verbatim text.
+#
+#     This is verbatim text.
+#       Whitespace is honored.     # See?
+#         Whitespace is honored.     # See?
+#
+#     This is still the same verbatim text block.
+#
+#   This is not verbatim text.
+#
+# A verbatim text block may not contain nested blocks of any kind
+# -- it's verbatim.
+#
+# ==== Code Blocks
+#
+# A special case of verbatim text is the <em>code block</em>,
+# which is merely verbatim text that \RDoc recognizes as Ruby code:
+#
+# In the rendered HTML, the code block:
+#
+# - Is indented.
+# - Has a contrasting background color.
+# - Has syntax highlighting.
+#
+# Example input:
+#
+#   Consider this method:
+#
+#     def foo(name = '', value = 0)
+#       @name = name      # Whitespace is still honored.
+#       @value = value
+#     end
+#
+#
+# Rendered HTML:
+# >>>
+#   Consider this method:
+#
+#     def foo(name = '', value = 0)
+#       @name = name      # Whitespace is still honored.
+#       @value = value
+#     end
+#
+# Pro tip:  If your indented Ruby code does not get highlighted,
+# it may contain a syntax error.
+#
+# A code block may not contain nested blocks of any kind
+# -- it's verbatim.
+#
+# ==== Block Quotes
+#
+# You can use the characters <tt>>>></tt> (unindented),
+# followed by indented text, to treat the text
+# as a {block quote}[https://en.wikipedia.org/wiki/Block_quotation]:
+#
+# Example input:
+#
+#   Here's a block quote:
+#   >>>
+#     Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer
+#     commodo quam iaculis massa posuere, dictum fringilla justo pulvinar.
+#     Quisque turpis erat, pharetra eu dui at, sollicitudin accumsan nulla.
+#
+#     Aenean congue ligula eu ligula molestie, eu pellentesque purus
+#     faucibus. In id leo non ligula condimentum lobortis. Duis vestibulum,
+#     diam in pellentesque aliquet, mi tellus placerat sapien, id euismod
+#     purus magna ut tortor.
+#
+# Rendered HTML:
+#
+# >>>
+#   Here's a block quote:
+#   >>>
+#     Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer
+#     commodo quam iaculis massa posuere, dictum fringilla justo pulvinar.
+#     Quisque turpis erat, pharetra eu dui at, sollicitudin accumsan nulla.
+#
+#     Aenean congue ligula eu ligula molestie, eu pellentesque purus

+#     diam in pellentesque aliquet, mi tellus placerat sapien, id euismod
+#     purus magna ut tortor.
+#
+# Note that, unlike verbatim text, single newlines are not honored,
+# but that a double newline begins a new paragraph in the block quote.
+#
+# A block quote may contain nested blocks, including:
+#
+# - Other block quotes.
+# - {Paragraphs}[rdoc-ref:RDoc::MarkupReference@Paragraphs].
+# - {Verbatim text blocks}[rdoc-ref:RDoc::MarkupReference@Verbatim+Text+Blocks].
+# - {Code blocks}[rdoc-ref:RDoc::MarkupReference@Code+Blocks].
+# - {Lists}[rdoc-ref:RDoc::MarkupReference@Lists].
+# - {Headings}[rdoc-ref:RDoc::MarkupReference@Headings].
+# - {Horizontal rules}[rdoc-ref:RDoc::MarkupReference@Horizontal+Rules].
+# - {Text Markup}[rdoc-ref:RDoc:MarkupReference@Text+Markup].
+#
+# ==== Lists
+#
+# Each type of list item is marked by a special beginning:
+#
+# - Bullet list item: Begins with a hyphen or asterisk.
+# - Numbered list item: Begins with digits and a period.
+# - Lettered list item: Begins with an alphabetic character and a period.
+# - Labeled list item: Begins with one of:
+#   - Square-bracketed text.
+#   - A word followed by two colons.
+#
+# A list begins with a list item and continues, even across blank lines,
+# as long as list items of the same type are found at the same indentation level.
+#
+# A new list resets the current margin inward.
+# Additional lines of text aligned at that margin
+# are part of the continuing list item.
+#
+# A list item may be continued on additional lines that are aligned
+# with the first line.  See examples below.
+#
+# A list item may contain nested blocks, including:
+#
+# - Other lists of any type.
+# - {Paragraphs}[rdoc-ref:RDoc::MarkupReference@Paragraphs].
+# - {Verbatim text blocks}[rdoc-ref:RDoc::MarkupReference@Verbatim+Text+Blocks].
+# - {Code blocks}[rdoc-ref:RDoc::MarkupReference@Code+Blocks].
+# - {Block quotes}[rdoc-ref:RDoc::MarkupReference@Block+Quotes].
+# - {Headings}[rdoc-ref:RDoc::MarkupReference@Headings].
+# - {Horizontal rules}[rdoc-ref:RDoc::MarkupReference@Horizontal+Rules].
+# - {Text Markup}[rdoc-ref:RDoc:MarkupReference@Text+Markup].
+#
+# ===== Bullet Lists
+#
+# A bullet list item begins with a hyphen or asterisk.
+#
+# Example input:
+#
+#   - An item.
+#   - Another.
+#   - An item spanning
+#     multiple lines.
+#
+#   * Yet another.
+#   - Last one.
+#
+# Rendered HTML:
+# >>>
+#   - An item.
+#   - Another.
+#   - An item spanning
+#     multiple lines.
+#
+#   * Yet another.
+#   - Last one.
+#
+# ===== Numbered Lists
+#
+# A numbered list item begins with digits and a period.
+#
+# The items are automatically re-numbered.
+#
+# Example input:
+#
+#   100. An item.
+#   10. Another.
+#   1. An item spanning
+#      multiple lines.
+#
+#   1. Yet another.
+#   1000. Last one.
+#

+#   1. An item spanning
+#      multiple lines.
+#
+#   1. Yet another.
+#   1000. Last one.
+#
+# ===== Lettered Lists
+#
+# A numbered list item begins with a letters and a period.
+#
+# The items are automatically "re-lettered."
+#
+# Example input:
+#
+#   z. An item.
+#   y. Another.
+#   x. An item spanning
+#      multiple lines.
+#
+#   x. Yet another.
+#   a. Last one.
+#
+# Rendered HTML:
+# >>>
+#   z. An item.
+#   y. Another.
+#
+#   x. Yet another.
+#   a. Last one.
+#
+# ===== Labeled Lists
+#
+# A labeled list item begins with one of:
+#
+# - Square-bracketed text: the label and text are on two lines.
+# - A word followed by two colons: the label and text are on the same line.
+#
+# Example input:
+#
+#   [foo] An item.
+#   bat:: Another.
+#   [bag] An item spanning
+#         multiple lines.

+#   bam:: Last one.
+#
+# ==== Headings
+#
+# A heading begins with up to six equal-signs, followed by heading text.
+# Whitespace between those and the heading text is optional.
+#
+# Examples:
+#
+#   = Section 1
+#   == Section 1.1
+#   === Section 1.1.1
+#   === Section 1.1.2
+#   == Section 1.2
+#   = Section 2
+#   = Foo
+#   == Bar
+#   === Baz
+#   ==== Bam
+#   ===== Bat
+#   ====== Bad
+#   ============Still a Heading (Level 6)
+#   \== Not a Heading
+#
+# A heading may contain only one type of nested block:
+#
+# - {Text Markup}[rdoc-ref:RDoc:MarkupReference@Text+Markup].
+#
+# ==== Horizontal Rules
+#
+# A horizontal rule consists of a line with three or more hyphens
+# and nothing more.
+#
+# Example input:
+#
+#   ---
+#   --- Not a horizontal rule.
+#
+#   -- Also not a horizontal rule.
+#   ---
+#
+# Rendered HTML:
+# >>>
+#   ---
+#   --- Not a horizontal rule.
+#
+#   -- Also not a horizontal rule.
+#   ---
+#
+# ==== Directives
+#
+# ===== Directives for Allowing or Suppressing Documentation
+#
+# - <tt># :stopdoc:</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that \RDoc should ignore markup
+#     until next <tt>:startdoc:</tt> directive or end-of-file.
+#
+# - <tt># :startdoc:</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that \RDoc should resume parsing markup.
+#
+# - <tt># :enddoc:</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that \RDoc should ignore markup to end-of-file
+#     regardless of other directives.
+#
+# - <tt># :nodoc:</tt>:
+#
+#   - Appended to a line of code
+#     that defines a class, module, method, alias, constant, or attribute.
+#   - Specifies that the defined object should not be documented.
+#
+# - <tt># :nodoc: all</tt>:
+#
+#   - Appended to a line of code
+#     that defines a class or module.
+#   - Specifies that the class or module should not be documented.
+#     By default, however, a nested class or module _will_ be documented.
+#
+# - <tt># :doc:</tt>:
+#
+#   - Appended to a line of code
+#     that defines a class, module, method, alias, constant, or attribute.
+#   - Specifies the defined object should be documented, even if otherwise
+#     would not be documented.
+#
+# - <tt># :notnew:</tt> (aliased as <tt>:not_new:</tt> and <tt>:not-new:</tt>):
+#
+#   - Appended to a line of code
+#     that defines instance method +initialize+.
+#   - Specifies that singleton method +new+ should not be documented.
+#     By default, Ruby fakes a corresponding singleton method +new+,
+#     which \RDoc includes in the documentation.
+#     Note that instance method +initialize+ is private, and so by default
+#     is not documented.
+#
+# For Ruby code, but not for other \RDoc sources,
+# there is a shorthand for <tt>:stopdoc:</tt> and <tt>:startdoc:</tt>:
+#
+#   # Documented.
+#   #--
+#   # Not documented.
+#   #++
+#   # Documented.
+#
+# For C code, any of directives <tt>:startdoc:</tt>, <tt>:enddoc:</tt>,
+# and <tt>:nodoc:</tt> may appear in a stand-alone comment:
+#
+#   /* :startdoc: */
+#   /* :stopdoc: */
+#   /* :enddoc: */
+#
+# ===== Directive for Specifying \RDoc Source Format
+#
+# - <tt># :markup: _type_</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies the format for the \RDoc input;
+#     parameter +type+ is one of +markdown+, +rd+, +rdoc+, +tomdoc+.
+#
+# ===== Directives for HTML Output
+#
+# - <tt># :title: _text_</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies the title for the HTML output.
+#
+# - <tt># :main: _filename_</tt>:
+#   - Appears on a line by itself.
+#   - Specifies the HTML file to be displayed first.
+#
+# ===== Directives for Method Documentation
+#
+# - <tt># :call-seq:</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies the calling sequence to be reported in the HTML,
+#     overriding the actual calling sequence in the code.
+#     See method #call_seq_directive.
+#
+#   Note that \RDoc can build the calling sequence for a Ruby-coded method,
+#   but not for other languages.
+#   You may want to override that by explicitly giving a <tt>:call-seq:</tt>
+#   directive if you want to include:
+#
+#   - A return type, which is not automatically inferred.
+#   - Multiple calling sequences.
+#
+#   For C code, the directive may appear in a stand-alone comment.
+#
+# - <tt># :args: _arg_names_</tt> (aliased as <tt>:arg:</tt>):
+#
+#   - Appears on a line by itself.
+#   - Specifies the arguments to be reported in the HTML,
+#     overriding the actual arguments in the code.
+#     See method #args_directive.
+#
+# - <tt># :yields: _arg_names_</tt> (aliased as <tt>:yield:</tt>):
+#
+#   - Appears on a line by itself.
+#   - Specifies the yield arguments to be reported in the HTML,
+#     overriding the actual yield in the code.
+#     See method #yields_directive.
+#
+# ===== Directives for Organizing Documentation
+#
+# By default, \RDoc groups:
+#
+# - Singleton methods together in alphabetical order.
+# - Instance methods and their aliases together in alphabetical order.
+# - Attributes and their aliases together in alphabetical order.
+#
+# You can use directives to modify those behaviors.
+#
+# - <tt># :section: _section_title_</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that following methods are to be grouped into the section
+#     with the given <em>section_title</em>,
+#     or into the default section if no title is given.
+#     The directive remains in effect until another such directive is given,
+#     but may be temporarily overridden by directive <tt>:category:</tt>.
+#     See below.
+#
+#   The comment block containing this directive:
+#
+#   - Must be separated by a blank line from the documentation for the next item.
+#   - May have one or more lines preceding the directive.
+#     These will be removed, along with any trailing lines that match them.
+#     Such lines may be visually helpful.
+#   - Lines of text that are not so removed become the descriptive text
+#     for the section.
+#
+#   Example:
+#
+#     # ----------------------------------------
+#     # :section: My Section
+#     # This is the section that I wrote.
+#     # See it glisten in the noon-day sun.
+#     # ----------------------------------------
+#
+#     ##
+#     # Comment for some_method
+#     def some_method
+#       # ...
+#     end
+#
+#   You can use directive <tt>:category:</tt> to temporarily
+#   override the current section.
+#
+# - <tt># :category: _section_title_</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that just one following method is to be included
+#     in the given section, or in the default section if no title is given.
+#     Subsequent methods are to be grouped into the current section.
+#
+# ===== Directive for Including a File
+#
+# - <tt># :include: _filepath_</tt>:
+#
+#   - Appears on a line by itself.
+#   - Specifies that the contents of the given file
+#     are to be included at this point.
+#     The file content is shifted to have the same indentation as the colon
+#     at the start of the directive.
+#
+#     The file is searched for in the directories
+#     given with the <tt>--include</tt> command-line option,
+#     or by default in the current directory.
+#
+#   For C code, the directive may appear in a stand-alone comment
+#
+# ==== Text Markup
+#
+# Text markup is metatext that affects HTML rendering:
+#
+# - Typeface: italic, bold, monofont.
+# - Character conversions: copyright, trademark, certain punctuation.
+# - Links.
+# - Escapes: marking text as "not markup."
+#
+# ===== Typeface Markup
+#
+# Typeface markup can specify that text is to be rendered
+# as italic, bold, or monofont.
+#
+# Typeface markup may contain only one type of nested block:

+# ==== Character Conversions
+#
+# Certain combinations of characters may be converted to special characters;
+# whether the conversion occurs depends on whether the special character
+# is available in the current encoding.
+#
+# - <tt>(c)</tt> converts to (c) (copyright character); must be lowercase.
+#
+# - <tt>(r)</tt> converts to (r) (registered trademark character); must be lowercase.
+#
+# - <tt>'foo'</tt> converts to 'foo' (smart single-quotes).
+#
+# - <tt>"foo"</tt> converts to "foo" (smart double-quotes).
+#
+# - <tt>foo ... bar</tt> converts to foo ... bar (1-character ellipsis).
+#
+# - <tt>foo -- bar</tt> converts to foo -- bar (1-character en-dash).
+#
+# - <tt>foo --- bar</tt> converts to foo --- bar (1-character em-dash).
+#
+# ==== Links
+#
+# Certain strings in \RDoc text are converted to links.
+# Any such link may be suppressed by prefixing a backslash.
+# This section shows how to link to various
+# targets.

+#
+# [<tt>rdoc-ref</tt> Scheme]
+#
+#   A link with the <tt>rdoc-ref:</tt> scheme links to the referenced item,

+#
+#
+# [<tt>rdoc-label</tt> Scheme]
+#
+#   [Simple]
+#
+#     You can specify a link target using this form,

+#
+#     This link refers to the constant +DUMMY_CONSTANT+ on this page:
+#
+#     - <tt>{DUMMY_CONSTANT}[rdoc-label:DUMMY_CONSTANT]</tt>
+#
+#     Thus:
+#
+#     {DUMMY_CONSTANT}[rdoc-label:DUMMY_CONSTANT]
+#
+#   [With Return]
+#
+#     You can specify both a link target and a local label
+#     that can be used as the target for a return link.
+#     These two links refer to each other:
+#
+#     - <tt>{go to addressee}[rdoc-label:addressee:sender]</tt>
+#     - <tt>{return to sender}[rdoc-label:sender:addressee]</tt>
+#
+#     Thus:
+#
+#     {go to addressee}[rdoc-label:addressee:sender]
+#
+#     Some text.
+#
+#     {return to sender}[rdoc-label:sender:addressee]
+#
+# [<tt>link:</tt> Scheme]
+#
+#   - <tt>link:README_rdoc.html</tt> links to link:README_rdoc.html.
+#
+# [<tt>rdoc-image</tt> Scheme]
+#
+#   Use the <tt>rdoc-image</tt> scheme to display an image that is also a link:
+#
+#     # {rdoc-image:path/to/image}[link_target]
+#
+#   - Link: <tt>{rdoc-image:https://www.ruby-lang.org/images/header-ruby-logo@2x.png}[https://www.ruby-lang.org]</tt>
+#     displays image <tt>https://www.ruby-lang.org/images/header-ruby-logo@2x.png</tt>
+#     as a link to <tt>https://www.ruby-lang.org</tt>.
+#
+#     {rdoc-image:https://www.ruby-lang.org/images/header-ruby-logo@2x.png}[https://www.ruby-lang.org]
+#
+#   A relative path as the target also works:
+#
+#   - Link: <tt>{rdoc-image:https://www.ruby-lang.org/images/header-ruby-logo@2x.png}[./Alias.html]</tt> links to <tt>./Alias.html</tt>
+#
+#     {rdoc-image:https://www.ruby-lang.org/images/header-ruby-logo@2x.png}[./Alias.html]
+#
+# === Escaping Text
+#
+# Text that would otherwise be interpreted as markup
+# can be "escaped," so that it is not interpreted as markup;
+# the escape character is the backslash (<tt>'\\'</tt>).
+#
+# In a verbatim text block or a code block,
+# the escape character is always preserved:
+#
+# Example input:
+#
+#   This is not verbatim text.
+#
+#     This is verbatim text, with an escape character \.
+#
+#   This is not a code block.
+#
+#     def foo
+#       'String with an escape character.'
+#     end
+#
+# Rendered HTML:
+#
+# >>>
+#   This is not verbatim text.
+#
+#     This is verbatim text, with an escape character \.
+#
+#   This is not a code block.
+#
+#     def foo
+#       'This is a code block with an escape character \.'
+#     end
+#
+# In typeface markup (italic, bold, or monofont),
+# an escape character is preserved unless it is immediately
+# followed by nested typeface markup.
+#
+# Example input:
+#
+#   This list is about escapes; it contains:
+#
+#   - <tt>Monofont text with unescaped nested _italic_</tt>.
+#   - <tt>Monofont text with escaped nested \_italic_</tt>.
+#   - <tt>Monofont text with an escape character \</tt>.

+#   - <tt>Monofont text with escaped nested \_italic_</tt>.
+#   - <tt>Monofont text with an escape character \ </tt>.
+#
+# In other text-bearing blocks
+# (paragraphs, block quotes, list items, headings):
+#
+# - A single escape character immediately followed by markup
+#   escapes the markup.
+# - A single escape character followed by whitespace is preserved.
+# - A single escape character anywhere else is ignored.
+# - A double escape character is rendered as a single backslash.
+#
+#   Example input:
+#
+#     This list is about escapes; it contains:
+#
+#     - An unescaped class name, RDoc, that will become a link.
+#     - An escaped class name, \RDoc, that will not become a link.
+#     - An escape character followed by whitespace \ .
+#     - An escape character \that is ignored.
+#     - A double escape character \\ that is rendered
+#       as a single backslash.
+#
+#   Rendered HTML:
+#
+#   >>>
+#     This list is about escapes; it contains:
+#

+#     - An escape character followed by whitespace \ .
+#     - An escape character \that is ignored.

+
+Regular expressions (<i>regexp</i>s) are patterns which describe the
+contents of a string. They're used for testing whether a string contains a
+given pattern, or extracting the portions that match. They are created
+with the <tt>/</tt><i>pat</i><tt>/</tt> and
+<tt>%r{</tt><i>pat</i><tt>}</tt> literals or the <tt>Regexp.new</tt>
+constructor.
+
+A regexp is usually delimited with forward slashes (<tt>/</tt>). For
+example:
+
+    /hay/ =~ 'haystack'   #=> 0
+    /y/.match('haystack') #=> #<MatchData "y">
+
+If a string contains the pattern it is said to <i>match</i>. A literal
+string matches itself.
+
+Here 'haystack' does not contain the pattern 'needle', so it doesn't match:
+
+    /needle/.match('haystack') #=> nil
+
+Here 'haystack' contains the pattern 'hay', so it matches:
+
+    /hay/.match('haystack')    #=> #<MatchData "hay">
+
+Specifically, <tt>/st/</tt> requires that the string contains the letter
+_s_ followed by the letter _t_, so it matches _haystack_, also.
+
+Note that any Regexp matching will raise a RuntimeError if timeout is set and
+exceeded. See {"Timeout"}[#label-Timeout] section in detail.
+
+== \Regexp Interpolation
+
+A regexp may contain interpolated strings; trivially:
+
+  foo = 'bar'
+  /#{foo}/ # => /bar/
+
+== <tt>=~</tt> and Regexp#match
+
+Pattern matching may be achieved by using <tt>=~</tt> operator or Regexp#match
+method.
+
+=== <tt>=~</tt> Operator
+
+<tt>=~</tt> is Ruby's basic pattern-matching operator.  When one operand is a
+regular expression and the other is a string then the regular expression is
+used as a pattern to match against the string.  (This operator is equivalently
+defined by Regexp and String so the order of String and Regexp do not matter.
+Other classes may have different implementations of <tt>=~</tt>.)  If a match
+is found, the operator returns index of first match in string, otherwise it
+returns +nil+.
+
+    /hay/ =~ 'haystack'   #=> 0
+    'haystack' =~ /hay/   #=> 0
+    /a/   =~ 'haystack'   #=> 1
+    /u/   =~ 'haystack'   #=> nil
+
+Using <tt>=~</tt> operator with a String and Regexp the <tt>$~</tt> global
+variable is set after a successful match.  <tt>$~</tt> holds a MatchData
+object. Regexp.last_match is equivalent to <tt>$~</tt>.
+
+=== Regexp#match Method
+
+The #match method returns a MatchData object:
+
+    /st/.match('haystack')   #=> #<MatchData "st">
+
+== Metacharacters and Escapes
+
+The following are <i>metacharacters</i> <tt>(</tt>, <tt>)</tt>,
+<tt>[</tt>, <tt>]</tt>, <tt>{</tt>, <tt>}</tt>, <tt>.</tt>, <tt>?</tt>,
+<tt>+</tt>, <tt>*</tt>. They have a specific meaning when appearing in a
+pattern. To match them literally they must be backslash-escaped. To match
+a backslash literally, backslash-escape it: <tt>\\\\</tt>.
+
+    /1 \+ 2 = 3\?/.match('Does 1 + 2 = 3?') #=> #<MatchData "1 + 2 = 3?">
+    /a\\\\b/.match('a\\\\b')                    #=> #<MatchData "a\\b">
+
+Patterns behave like double-quoted strings and can contain the same
+backslash escapes (the meaning of <tt>\s</tt> is different, however,
+see below[#label-Character+Classes]).
+
+    /\s\u{6771 4eac 90fd}/.match("Go to 東京都")
+        #=> #<MatchData " 東京都">
+
+Arbitrary Ruby expressions can be embedded into patterns with the
+<tt>#{...}</tt> construct.
+
+    place = "東京都"
+    /#{place}/.match("Go to 東京都")
+        #=> #<MatchData "東京都">
+
+== Character Classes
+
+A <i>character class</i> is delimited with square brackets (<tt>[</tt>,
+<tt>]</tt>) and lists characters that may appear at that point in the
+match. <tt>/[ab]/</tt> means _a_ or _b_, as opposed to <tt>/ab/</tt> which
+means _a_ followed by _b_.
+
+    /W[aeiou]rd/.match("Word") #=> #<MatchData "Word">
+
+Within a character class the hyphen (<tt>-</tt>) is a metacharacter
+denoting an inclusive range of characters. <tt>[abcd]</tt> is equivalent
+to <tt>[a-d]</tt>. A range can be followed by another range, so
+<tt>[abcdwxyz]</tt> is equivalent to <tt>[a-dw-z]</tt>. The order in which
+ranges or individual characters appear inside a character class is
+irrelevant.
+
+    /[0-9a-f]/.match('9f') #=> #<MatchData "9">
+    /[9f]/.match('9f')     #=> #<MatchData "9">
+
+If the first character of a character class is a caret (<tt>^</tt>) the
+class is inverted: it matches any character _except_ those named.
+
+    /[^a-eg-z]/.match('f') #=> #<MatchData "f">
+
+A character class may contain another character class. By itself this
+isn't useful because <tt>[a-z[0-9]]</tt> describes the same set as
+<tt>[a-z0-9]</tt>. However, character classes also support the <tt>&&</tt>
+operator which performs set intersection on its arguments. The two can be
+combined as follows:
+
+    /[a-w&&[^c-g]z]/ # ([a-w] AND ([^c-g] OR z))
+
+This is equivalent to:
+
+    /[abh-w]/
+
+The following metacharacters also behave like character classes:
+
+* <tt>/./</tt> - Any character except a newline.
+* <tt>/./m</tt> - Any character (the +m+ modifier enables multiline mode)
+* <tt>/\w/</tt> - A word character (<tt>[a-zA-Z0-9_]</tt>)
+* <tt>/\W/</tt> - A non-word character (<tt>[^a-zA-Z0-9_]</tt>).
+  Please take a look at {Bug #4044}[https://bugs.ruby-lang.org/issues/4044] if
+  using <tt>/\W/</tt> with the <tt>/i</tt> modifier.
+* <tt>/\d/</tt> - A digit character (<tt>[0-9]</tt>)
+* <tt>/\D/</tt> - A non-digit character (<tt>[^0-9]</tt>)
+* <tt>/\h/</tt> - A hexdigit character (<tt>[0-9a-fA-F]</tt>)
+* <tt>/\H/</tt> - A non-hexdigit character (<tt>[^0-9a-fA-F]</tt>)
+* <tt>/\s/</tt> - A whitespace character: <tt>/[ \t\r\n\f\v]/</tt>
+* <tt>/\S/</tt> - A non-whitespace character: <tt>/[^ \t\r\n\f\v]/</tt>
+* <tt>/\R/</tt> - A linebreak: <tt>\n</tt>, <tt>\v</tt>, <tt>\f</tt>, <tt>\r</tt>
+  <tt>\u0085</tt> (NEXT LINE), <tt>\u2028</tt> (LINE SEPARATOR), <tt>\u2029</tt> (PARAGRAPH SEPARATOR)
+  or <tt>\r\n</tt>.
+
+POSIX <i>bracket expressions</i> are also similar to character classes.
+They provide a portable alternative to the above, with the added benefit
+that they encompass non-ASCII characters. For instance, <tt>/\d/</tt>
+matches only the ASCII decimal digits (0-9); whereas <tt>/[[:digit:]]/</tt>
+matches any character in the Unicode _Nd_ category.
+
+* <tt>/[[:alnum:]]/</tt> - Alphabetic and numeric character
+* <tt>/[[:alpha:]]/</tt> - Alphabetic character
+* <tt>/[[:blank:]]/</tt> - Space or tab
+* <tt>/[[:cntrl:]]/</tt> - Control character
+* <tt>/[[:digit:]]/</tt> - Digit
+* <tt>/[[:graph:]]/</tt> - Non-blank character (excludes spaces, control
+  characters, and similar)
+* <tt>/[[:lower:]]/</tt> - Lowercase alphabetical character
+* <tt>/[[:print:]]/</tt> - Like [:graph:], but includes the space character
+* <tt>/[[:punct:]]/</tt> - Punctuation character
+* <tt>/[[:space:]]/</tt> - Whitespace character (<tt>[:blank:]</tt>, newline,
+  carriage return, etc.)
+* <tt>/[[:upper:]]/</tt> - Uppercase alphabetical
+* <tt>/[[:xdigit:]]/</tt> - Digit allowed in a hexadecimal number (i.e.,
+  0-9a-fA-F)
+
+Ruby also supports the following non-POSIX character classes:
+
+* <tt>/[[:word:]]/</tt> - A character in one of the following Unicode
+  general categories _Letter_, _Mark_, _Number_,
+  <i>Connector_Punctuation</i>
+* <tt>/[[:ascii:]]/</tt> - A character in the ASCII character set
+
+    # U+06F2 is "EXTENDED ARABIC-INDIC DIGIT TWO"
+    /[[:digit:]]/.match("\u06F2")    #=> #<MatchData "\u{06F2}">
+    /[[:upper:]][[:lower:]]/.match("Hello") #=> #<MatchData "He">
+    /[[:xdigit:]][[:xdigit:]]/.match("A6")  #=> #<MatchData "A6">
+
+== Repetition
+
+The constructs described so far match a single character. They can be
+followed by a repetition metacharacter to specify how many times they need
+to occur. Such metacharacters are called <i>quantifiers</i>.
+
+* <tt>*</tt> - Zero or more times
+* <tt>+</tt> - One or more times
+* <tt>?</tt> - Zero or one times (optional)
+* <tt>{</tt><i>n</i><tt>}</tt> - Exactly <i>n</i> times
+* <tt>{</tt><i>n</i><tt>,}</tt> - <i>n</i> or more times
+* <tt>{,</tt><i>m</i><tt>}</tt> - <i>m</i> or less times
+* <tt>{</tt><i>n</i><tt>,</tt><i>m</i><tt>}</tt> - At least <i>n</i> and
+  at most <i>m</i> times
+
+At least one uppercase character ('H'), at least one lowercase character
+('e'), two 'l' characters, then one 'o':
+
+    "Hello".match(/[[:upper:]]+[[:lower:]]+l{2}o/) #=> #<MatchData "Hello">
+
+=== Greedy Match
+
+Repetition is <i>greedy</i> by default: as many occurrences as possible
+are matched while still allowing the overall match to succeed. By
+contrast, <i>lazy</i> matching makes the minimal amount of matches
+necessary for overall success. Most greedy metacharacters can be made lazy
+by following them with <tt>?</tt>. For the <tt>{n}</tt> pattern, because
+it specifies an exact number of characters to match and not a variable
+number of characters, the <tt>?</tt> metacharacter instead makes the
+repeated pattern optional.
+
+Both patterns below match the string. The first uses a greedy quantifier so
+'.+' matches '<a><b>'; the second uses a lazy quantifier so '.+?' matches
+'<a>':
+
+    /<.+>/.match("<a><b>")  #=> #<MatchData "<a><b>">
+    /<.+?>/.match("<a><b>") #=> #<MatchData "<a>">
+
+=== Possessive Match
+
+A quantifier followed by <tt>+</tt> matches <i>possessively</i>: once it
+has matched it does not backtrack. They behave like greedy quantifiers,
+but having matched they refuse to "give up" their match even if this
+jeopardises the overall match.
+
+    /<.*><.+>/.match("<a><b>") #=> #<MatchData "<a><b>">
+    /<.*+><.+>/.match("<a><b>") #=> nil
+    /<.*><.++>/.match("<a><b>") #=> nil
+
+== Capturing
+
+Parentheses can be used for <i>capturing</i>. The text enclosed by the
+<i>n</i>th group of parentheses can be subsequently referred to
+with <i>n</i>. Within a pattern use the <i>backreference</i>
+<tt>\n</tt> (e.g. <tt>\1</tt>); outside of the pattern use
+<tt>MatchData[n]</tt> (e.g. <tt>MatchData[1]</tt>).
+
+In this example, <tt>'at'</tt> is captured by the first group of
+parentheses, then referred to later with <tt>\1</tt>:
+
+    /[csh](..) [csh]\1 in/.match("The cat sat in the hat")
+        #=> #<MatchData "cat sat in" 1:"at">
+
+Regexp#match returns a MatchData object which makes the captured text
+available with its #[] method:
+
+    /[csh](..) [csh]\1 in/.match("The cat sat in the hat")[1] #=> 'at'
+
+While Ruby supports an arbitrary number of numbered captured groups,
+only groups 1-9 are supported using the <tt>\n</tt> backreference
+syntax.
+
+Ruby also supports <tt>\0</tt> as a special backreference, which
+references the entire matched string.  This is also available at
+<tt>MatchData[0]</tt>.  Note that the <tt>\0</tt> backreference cannot
+be used inside the regexp, as backreferences can only be used after the
+end of the capture group, and the <tt>\0</tt> backreference uses the
+implicit capture group of the entire match.  However, you can use
+this backreference when doing substitution:
+
+  "The cat sat in the hat".gsub(/[csh]at/, '\0s')
+    # => "The cats sats in the hats"
+
+=== Named Captures
+
+Capture groups can be referred to by name when defined with the
+<tt>(?<</tt><i>name</i><tt>>)</tt> or <tt>(?'</tt><i>name</i><tt>')</tt>
+constructs.
+
+    /\$(?<dollars>\d+)\.(?<cents>\d+)/.match("$3.67")
+        #=> #<MatchData "$3.67" dollars:"3" cents:"67">
+    /\$(?<dollars>\d+)\.(?<cents>\d+)/.match("$3.67")[:dollars] #=> "3"
+
+Named groups can be backreferenced with <tt>\k<</tt><i>name</i><tt>></tt>,
+where _name_ is the group name.
+
+    /(?<vowel>[aeiou]).\k<vowel>.\k<vowel>/.match('ototomy')
+        #=> #<MatchData "ototo" vowel:"o">
+
+*Note*: A regexp can't use named backreferences and numbered
+backreferences simultaneously. Also, if a named capture is used in a
+regexp, then parentheses used for grouping which would otherwise result
+in a unnamed capture are treated as non-capturing.
+
+    /(\w)(\w)/.match("ab").captures # => ["a", "b"]
+    /(\w)(\w)/.match("ab").named_captures # => {}
+
+    /(?<c>\w)(\w)/.match("ab").captures # => ["a"]
+    /(?<c>\w)(\w)/.match("ab").named_captures # => {"c"=>"a"}
+
+When named capture groups are used with a literal regexp on the left-hand
+side of an expression and the <tt>=~</tt> operator, the captured text is
+also assigned to local variables with corresponding names.
+
+    /\$(?<dollars>\d+)\.(?<cents>\d+)/ =~ "$3.67" #=> 0
+    dollars #=> "3"
+
+== Grouping
+
+Parentheses also <i>group</i> the terms they enclose, allowing them to be
+quantified as one <i>atomic</i> whole.
+
+The pattern below matches a vowel followed by 2 word characters:
+
+    /[aeiou]\w{2}/.match("Caenorhabditis elegans") #=> #<MatchData "aen">
+
+Whereas the following pattern matches a vowel followed by a word character,
+twice, i.e. <tt>[aeiou]\w[aeiou]\w</tt>: 'enor'.
+
+    /([aeiou]\w){2}/.match("Caenorhabditis elegans")
+        #=> #<MatchData "enor" 1:"or">
+
+The <tt>(?:</tt>...<tt>)</tt> construct provides grouping without
+capturing. That is, it combines the terms it contains into an atomic whole
+without creating a backreference. This benefits performance at the slight
+expense of readability.
+
+The first group of parentheses captures 'n' and the second 'ti'. The second
+group is referred to later with the backreference <tt>\2</tt>:
+
+    /I(n)ves(ti)ga\2ons/.match("Investigations")
+        #=> #<MatchData "Investigations" 1:"n" 2:"ti">
+
+The first group of parentheses is now made non-capturing with '?:', so it
+still matches 'n', but doesn't create the backreference. Thus, the
+backreference <tt>\1</tt> now refers to 'ti'.
+
+    /I(?:n)ves(ti)ga\1ons/.match("Investigations")
+        #=> #<MatchData "Investigations" 1:"ti">
+
+=== Atomic Grouping
+
+Grouping can be made <i>atomic</i> with
+<tt>(?></tt><i>pat</i><tt>)</tt>. This causes the subexpression <i>pat</i>
+to be matched independently of the rest of the expression such that what
+it matches becomes fixed for the remainder of the match, unless the entire
+subexpression must be abandoned and subsequently revisited. In this
+way <i>pat</i> is treated as a non-divisible whole. Atomic grouping is
+typically used to optimise patterns so as to prevent the regular
+expression engine from backtracking needlessly.
+
+The <tt>"</tt> in the pattern below matches the first character of the string,
+then <tt>.*</tt> matches <i>Quote"</i>. This causes the overall match to fail,
+so the text matched by <tt>.*</tt> is backtracked by one position, which
+leaves the final character of the string available to match <tt>"</tt>
+
+          /".*"/.match('"Quote"')     #=> #<MatchData "\"Quote\"">
+
+If <tt>.*</tt> is grouped atomically, it refuses to backtrack <i>Quote"</i>,
+even though this means that the overall match fails
+
+    /"(?>.*)"/.match('"Quote"') #=> nil
+
+== Subexpression Calls
+
+The <tt>\g<</tt><i>name</i><tt>></tt> syntax matches the previous
+subexpression named _name_, which can be a group name or number, again.
+This differs from backreferences in that it re-executes the group rather
+than simply trying to re-match the same text.
+
+This pattern matches a <i>(</i> character and assigns it to the <tt>paren</tt>
+group, tries to call that the <tt>paren</tt> sub-expression again but fails,
+then matches a literal <i>)</i>:
+
+    /\A(?<paren>\(\g<paren>*\))*\z/ =~ '()'
+
+
+    /\A(?<paren>\(\g<paren>*\))*\z/ =~ '(())' #=> 0
+    # ^1
+    #      ^2
+    #           ^3
+    #                 ^4
+    #      ^5
+    #           ^6
+    #                      ^7
+    #                       ^8
+    #                       ^9
+    #                           ^10
+
+1.  Matches at the beginning of the string, i.e. before the first
+    character.
+2.  Enters a named capture group called <tt>paren</tt>
+3.  Matches a literal <i>(</i>, the first character in the string
+4.  Calls the <tt>paren</tt> group again, i.e. recurses back to the
+    second step
+5.  Re-enters the <tt>paren</tt> group
+6.  Matches a literal <i>(</i>, the second character in the
+    string
+7.  Try to call <tt>paren</tt> a third time, but fail because
+    doing so would prevent an overall successful match
+8.  Match a literal <i>)</i>, the third character in the string.
+    Marks the end of the second recursive call
+9.  Match a literal <i>)</i>, the fourth character in the string
+10. Match the end of the string
+
+== Alternation
+
+The vertical bar metacharacter (<tt>|</tt>) combines several expressions into
+a single one that matches any of the expressions. Each expression is an
+<i>alternative</i>.
+
+    /\w(and|or)\w/.match("Feliformia") #=> #<MatchData "form" 1:"or">
+    /\w(and|or)\w/.match("furandi")    #=> #<MatchData "randi" 1:"and">
+    /\w(and|or)\w/.match("dissemblance") #=> nil
+
+== Character Properties

+following scripts are supported: <i>Arabic</i>, <i>Armenian</i>,
+<i>Balinese</i>, <i>Bengali</i>, <i>Bopomofo</i>, <i>Braille</i>,
+<i>Buginese</i>, <i>Buhid</i>, <i>Canadian_Aboriginal</i>, <i>Carian</i>,

+
+Unicode codepoint U+06E9 is named "ARABIC PLACE OF SAJDAH" and belongs to the
+Arabic script:
+
+    /\p{Arabic}/.match("\u06E9") #=> #<MatchData "\u06E9">
+
+All character properties can be inverted by prefixing their name with a
+caret (<tt>^</tt>).
+
+Letter 'A' is not in the Unicode Ll (Letter; Lowercase) category, so this
+match succeeds:
+
+    /\p{^Ll}/.match("A") #=> #<MatchData "A">
+
+== Anchors
+
+Anchors are metacharacter that match the zero-width positions between
+characters, <i>anchoring</i> the match to a specific position.
+
+* <tt>^</tt> - Matches beginning of line
+* <tt>$</tt> - Matches end of line
+* <tt>\A</tt> - Matches beginning of string.
+* <tt>\Z</tt> - Matches end of string. If string ends with a newline,
+  it matches just before newline
+* <tt>\z</tt> - Matches end of string
+* <tt>\G</tt> - Matches first matching position:
+
+  In methods like <tt>String#gsub</tt> and <tt>String#scan</tt>, it changes on each iteration.
+  It initially matches the beginning of subject, and in each following iteration it matches where the last match finished.
+
+      "    a b c".gsub(/ /, '_')    #=> "____a_b_c"
+      "    a b c".gsub(/\G /, '_')  #=> "____a b c"
+
+  In methods like <tt>Regexp#match</tt> and <tt>String#match</tt> that take an (optional) offset, it matches where the search begins.
+
+      "hello, world".match(/,/, 3)    #=> #<MatchData ",">
+      "hello, world".match(/\G,/, 3)  #=> nil
+
+* <tt>\b</tt> - Matches word boundaries when outside brackets;
+  backspace (0x08) when inside brackets
+* <tt>\B</tt> - Matches non-word boundaries
+* <tt>(?=</tt><i>pat</i><tt>)</tt> - <i>Positive lookahead</i> assertion:
+  ensures that the following characters match <i>pat</i>, but doesn't
+  include those characters in the matched text
+* <tt>(?!</tt><i>pat</i><tt>)</tt> - <i>Negative lookahead</i> assertion:
+  ensures that the following characters do not match <i>pat</i>, but
+  doesn't include those characters in the matched text
+* <tt>(?<=</tt><i>pat</i><tt>)</tt> - <i>Positive lookbehind</i>
+  assertion: ensures that the preceding characters match <i>pat</i>, but
+  doesn't include those characters in the matched text
+* <tt>(?<!</tt><i>pat</i><tt>)</tt> - <i>Negative lookbehind</i>
+  assertion: ensures that the preceding characters do not match
+  <i>pat</i>, but doesn't include those characters in the matched text
+
+* <tt>\K</tt> - <i>Match reset</i>: the matched content preceding
+  <tt>\K</tt> in the regexp is excluded from the result.  For example,
+  the following two regexps are almost equivalent:
+
+      /ab\Kc/ =~ "abc"     #=> 0
+      /(?<=ab)c/ =~ "abc"  #=> 2
+
+  These match same string and <i>$&</i> equals <tt>"c"</tt>, while the
+  matched position is different.
+
+  As are the following two regexps:
+
+      /(a)\K(b)\Kc/
+      /(?<=(?<=(a))(b))c/
+
+If a pattern isn't anchored it can begin at any point in the string:
+
+    /real/.match("surrealist") #=> #<MatchData "real">
+
+Anchoring the pattern to the beginning of the string forces the match to start
+there. 'real' doesn't occur at the beginning of the string, so now the match
+fails:
+
+    /\Areal/.match("surrealist") #=> nil
+
+The match below fails because although 'Demand' contains 'and', the pattern
+does not occur at a word boundary.
+
+    /\band/.match("Demand")
+
+Whereas in the following example 'and' has been anchored to a non-word
+boundary so instead of matching the first 'and' it matches from the fourth
+letter of 'demand' instead:
+
+    /\Band.+/.match("Supply and demand curve") #=> #<MatchData "and curve">
+
+The pattern below uses positive lookahead and positive lookbehind to match
+text appearing in <b></b> tags without including the tags in the match:
+
+    /(?<=<b>)\w+(?=<\/b>)/.match("Fortune favours the <b>bold</b>")
+        #=> #<MatchData "bold">
+
+== Options
+
+The end delimiter for a regexp can be followed by one or more single-letter
+options which control how the pattern can match.
+
+* <tt>/pat/i</tt> - Ignore case
+* <tt>/pat/m</tt> - Treat a newline as a character matched by <tt>.</tt>
+* <tt>/pat/x</tt> - Ignore whitespace and comments in the pattern
+* <tt>/pat/o</tt> - Perform <tt>#{}</tt> interpolation only once
+
+<tt>i</tt>, <tt>m</tt>, and <tt>x</tt> can also be applied on the
+subexpression level with the
+<tt>(?</tt><i>on</i><tt>-</tt><i>off</i><tt>)</tt> construct, which
+enables options <i>on</i>, and disables options <i>off</i> for the
+expression enclosed by the parentheses:
+
+    /a(?i:b)c/.match('aBc')   #=> #<MatchData "aBc">
+    /a(?-i:b)c/i.match('ABC') #=> nil
+
+Additionally, these options can also be toggled for the remainder of the
+pattern:
+
+    /a(?i)bc/.match('abC') #=> #<MatchData "abC">
+
+Options may also be used with <tt>Regexp.new</tt>:
+
+    Regexp.new("abc", Regexp::IGNORECASE)                     #=> /abc/i
+    Regexp.new("abc", Regexp::MULTILINE)                      #=> /abc/m
+    Regexp.new("abc # Comment", Regexp::EXTENDED)             #=> /abc # Comment/x
+    Regexp.new("abc", Regexp::IGNORECASE | Regexp::MULTILINE) #=> /abc/mi
+
+    Regexp.new("abc", "i")           #=> /abc/i
+    Regexp.new("abc", "m")           #=> /abc/m
+    Regexp.new("abc # Comment", "x") #=> /abc # Comment/x
+    Regexp.new("abc", "im")          #=> /abc/mi
+
+== Free-Spacing Mode and Comments
+
+As mentioned above, the <tt>x</tt> option enables <i>free-spacing</i>
+mode. Literal white space inside the pattern is ignored, and the
+octothorpe (<tt>#</tt>) character introduces a comment until the end of
+the line. This allows the components of the pattern to be organized in a
+potentially more readable fashion.
+
+A contrived pattern to match a number with optional decimal places:
+
+    float_pat = /\A
+        [[:digit:]]+ # 1 or more digits before the decimal point
+        (\.          # Decimal point
+            [[:digit:]]+ # 1 or more digits after the decimal point
+        )? # The decimal point and following digits are optional
+    \Z/x
+    float_pat.match('3.14') #=> #<MatchData "3.14" 1:".14">
+
+There are a number of strategies for matching whitespace:
+
+* Use a pattern such as <tt>\s</tt> or <tt>\p{Space}</tt>.
+* Use escaped whitespace such as <tt>\ </tt>, i.e. a space preceded by a backslash.
+* Use a character class such as <tt>[ ]</tt>.
+
+Comments can be included in a non-<tt>x</tt> pattern with the
+<tt>(?#</tt><i>comment</i><tt>)</tt> construct, where <i>comment</i> is
+arbitrary text ignored by the regexp engine.
+
+Comments in regexp literals cannot include unescaped terminator
+characters.
+
+== Encoding
+
+Regular expressions are assumed to use the source encoding. This can be
+overridden with one of the following modifiers.
+
+* <tt>/</tt><i>pat</i><tt>/u</tt> - UTF-8
+* <tt>/</tt><i>pat</i><tt>/e</tt> - EUC-JP
+* <tt>/</tt><i>pat</i><tt>/s</tt> - Windows-31J
+* <tt>/</tt><i>pat</i><tt>/n</tt> - ASCII-8BIT
+
+A regexp can be matched against a string when they either share an
+encoding, or the regexp's encoding is _US-ASCII_ and the string's encoding
+is ASCII-compatible.
+
+If a match between incompatible encodings is attempted an
+<tt>Encoding::CompatibilityError</tt> exception is raised.
+
+The <tt>Regexp#fixed_encoding?</tt> predicate indicates whether the regexp
+has a <i>fixed</i> encoding, that is one incompatible with ASCII. A
+regexp's encoding can be explicitly fixed by supplying
+<tt>Regexp::FIXEDENCODING</tt> as the second argument of
+<tt>Regexp.new</tt>:
+
+    r = Regexp.new("a".force_encoding("iso-8859-1"),Regexp::FIXEDENCODING)
+    r =~ "a\u3042"
+       # raises Encoding::CompatibilityError: incompatible encoding regexp match
+       #         (ISO-8859-1 regexp with UTF-8 string)
+
+== \Regexp Global Variables
+
+Pattern matching sets some global variables :
+
+* <tt>$~</tt> is equivalent to Regexp.last_match;
+* <tt>$&</tt> contains the complete matched text;
+* <tt>$`</tt> contains string before match;
+* <tt>$'</tt> contains string after match;
+* <tt>$1</tt>, <tt>$2</tt> and so on contain text matching first, second, etc
+  capture group;
+* <tt>$+</tt> contains last capture group.
+
+Example:
+
+    m = /s(\w{2}).*(c)/.match('haystack') #=> #<MatchData "stac" 1:"ta" 2:"c">
+    $~                                    #=> #<MatchData "stac" 1:"ta" 2:"c">
+    Regexp.last_match                     #=> #<MatchData "stac" 1:"ta" 2:"c">
+
+    $&      #=> "stac"
+            # same as m[0]
+    $`      #=> "hay"
+            # same as m.pre_match
+    $'      #=> "k"
+            # same as m.post_match
+    $1      #=> "ta"
+            # same as m[1]
+    $2      #=> "c"
+            # same as m[2]
+    $3      #=> nil
+            # no third group in pattern
+    $+      #=> "c"
+            # same as m[-1]
+
+These global variables are thread-local and method-local variables.
+
+== Performance
+
+Certain pathological combinations of constructs can lead to abysmally bad
+performance.
+
+Consider a string of 25 <i>a</i>s, a <i>d</i>, 4 <i>a</i>s, and a
+<i>c</i>.
+
+    s = 'a' * 25 + 'd' + 'a' * 4 + 'c'
+    #=> "aaaaaaaaaaaaaaaaaaaaaaaaadaaaac"
+
+The following patterns match instantly as you would expect:
+
+    /(b|a)/ =~ s #=> 0
+    /(b|a+)/ =~ s #=> 0
+    /(b|a+)*/ =~ s #=> 0
+
+However, the following pattern takes appreciably longer:
+
+    /(b|a+)*c/ =~ s #=> 26
+
+This happens because an atom in the regexp is quantified by both an
+immediate <tt>+</tt> and an enclosing <tt>*</tt> with nothing to
+differentiate which is in control of any particular character. The
+nondeterminism that results produces super-linear performance. (Consult
+<i>Mastering Regular Expressions</i> (3rd ed.), pp 222, by
+<i>Jeffery Friedl</i>, for an in-depth analysis). This particular case
+can be fixed by use of atomic grouping, which prevents the unnecessary
+backtracking:
+
+    (start = Time.now) && /(b|a+)*c/ =~ s && (Time.now - start)
+       #=> 24.702736882
+    (start = Time.now) && /(?>b|a+)*c/ =~ s && (Time.now - start)
+       #=> 0.000166571
+
+A similar case is typified by the following example, which takes
+approximately 60 seconds to execute for me:
+
+Match a string of 29 <i>a</i>s against a pattern of 29 optional <i>a</i>s
+followed by 29 mandatory <i>a</i>s:
+
+    Regexp.new('a?' * 29 + 'a' * 29) =~ 'a' * 29
+
+The 29 optional <i>a</i>s match the string, but this prevents the 29
+mandatory <i>a</i>s that follow from matching. Ruby must then backtrack
+repeatedly so as to satisfy as many of the optional matches as it can
+while still matching the mandatory 29. It is plain to us that none of the
+optional matches can succeed, but this fact unfortunately eludes Ruby.
+
+The best way to improve performance is to significantly reduce the amount of
+backtracking needed.  For this case, instead of individually matching 29
+optional <i>a</i>s, a range of optional <i>a</i>s can be matched all at once
+with <i>a{0,29}</i>:
+
+    Regexp.new('a{0,29}' + 'a' * 29) =~ 'a' * 29
+
+== Timeout
+
+There are two APIs to set timeout. One is Regexp.timeout=, which is
+process-global configuration of timeout for Regexp matching.
+
+    Regexp.timeout = 3
+    s = 'a' * 25 + 'd' + 'a' * 4 + 'c'
+    /(b|a+)*c/ =~ s  #=> This raises an exception in three seconds
+
+The other is timeout keyword of Regexp.new.
+
+    re = Regexp.new("(b|a+)*c", timeout: 3)
+    s = 'a' * 25 + 'd' + 'a' * 4 + 'c'
+    /(b|a+)*c/ =~ s  #=> This raises an exception in three seconds
+
+When using Regexps to process untrusted input, you should use the timeout
+feature to avoid excessive backtracking. Otherwise, a malicious user can
+provide input to Regexp causing Denial-of-Service attack.
+Note that the timeout is not set by default because an appropriate limit
+highly depends on an application requirement and context.

+= Ruby Security
+
+The Ruby programming language is large and complex and there are many security
+pitfalls often encountered by newcomers and experienced Rubyists alike.
+
+This document aims to discuss many of these pitfalls and provide more secure
+alternatives where applicable.
+
+Please check the full list of publicly known CVEs and how to correctly report a
+security vulnerability, at: https://www.ruby-lang.org/en/security/
+Japanese version is here: https://www.ruby-lang.org/ja/security/
+
+Security vulnerabilities should be reported via an email to
+mailto:security@ruby-lang.org ({the PGP public
+key}[https://www.ruby-lang.org/security.asc]), which is a private mailing list.
+Reported problems will be published after fixes.
+
+== +Marshal.load+
+
+Ruby's +Marshal+ module provides methods for serializing and deserializing Ruby
+object trees to and from a binary data format.
+
+Never use +Marshal.load+ to deserialize untrusted or user supplied data.
+Because +Marshal+ can deserialize to almost any Ruby object and has full
+control over instance variables, it is possible to craft a malicious payload
+that executes code shortly after deserialization.
+
+If you need to deserialize untrusted data, you should use JSON as it is only
+capable of returning 'primitive' types such as strings, arrays, hashes, numbers
+and nil. If you need to deserialize other classes, you should handle this
+manually. Never deserialize to a user specified class.
+
+== YAML
+
+YAML is a popular human readable data serialization format used by many Ruby
+programs for configuration and database persistence of Ruby object trees.
+
+Similar to +Marshal+, it is able to deserialize into arbitrary Ruby classes.
+For example, the following YAML data will create an +ERB+ object when
+deserialized:
+
+  !ruby/object:ERB
+  src: puts `uname`
+
+Because of this, many of the security considerations applying to Marshal are
+also applicable to YAML. Do not use YAML to deserialize untrusted data.
+
+== Symbols
+
+Symbols are often seen as syntax sugar for simple strings, but they play a much
+more crucial role. The MRI Ruby implementation uses Symbols internally for
+method, variable and constant names. The reason for this is that symbols are
+simply integers with names attached to them, so they are faster to look up in
+hashtables.
+
+Starting in version 2.2, most symbols can be garbage collected; these are
+called <i>mortal</i> symbols. Most symbols you create (e.g. by calling
++to_sym+) are mortal.
+
+<i>Immortal</i> symbols on the other hand will never be garbage collected.
+They are created when modifying code:
+* defining a method (e.g. with +define_method+),
+* setting an instance variable (e.g. with +instance_variable_set+),
+* creating a variable or constant (e.g. with +const_set+)
+C extensions that have not been updated and are still calling `SYM2ID`
+will create immortal symbols.
+Bugs in 2.2.0: +send+ and +__send__+ also created immortal symbols,
+and calling methods with keyword arguments could also create some.
+
+Don't create immortal symbols from user inputs. Otherwise, this would
+allow a user to mount a denial of service attack against your application by
+flooding it with unique strings, which will cause memory to grow indefinitely
+until the Ruby process is killed or causes the system to slow to a halt.
+
+While it might not be a good idea to call these with user inputs, methods that
+used to be vulnerable such as +to_sym+, +respond_to?+,
++method+, +instance_variable_get+, +const_get+, etc. are no longer a threat.
+
+== Regular expressions
+
+Ruby's regular expression syntax has some minor differences when compared to
+other languages. In Ruby, the <code>^</code> and <code>$</code> anchors do not
+refer to the beginning and end of the string, rather the beginning and end of a
+*line*.
+
+This means that if you're using a regular expression like
+<code>/^[a-z]+$/</code> to restrict a string to only letters, an attacker can
+bypass this check by passing a string containing a letter, then a newline, then
+any string of their choosing.
+
+If you want to match the beginning and end of the entire string in Ruby, use
+the anchors +\A+ and +\z+.
+
+== +eval+
+
+Never pass untrusted or user controlled input to +eval+.
+
+Unless you are implementing a REPL like +irb+ or +pry+, +eval+ is almost
+certainly not what you want. Do not attempt to filter user input before passing
+it to +eval+ - this approach is fraught with danger and will most likely open
+your application up to a serious remote code execution vulnerability.
+
+== +send+
+
+'Global functions' in Ruby (+puts+, +exit+, etc.) are actually private instance
+methods on +Object+. This means it is possible to invoke these methods with
++send+, even if the call to +send+ has an explicit receiver.
+
+For example, the following code snippet writes "Hello world" to the terminal:
+
+  1.send(:puts, "Hello world")
+
+You should never call +send+ with user supplied input as the first parameter.
+Doing so can introduce a denial of service vulnerability:
+
+  foo.send(params[:bar]) # params[:bar] is "exit!"
+
+If an attacker can control the first two arguments to +send+, remote code
+execution is possible:
+
+  # params is { :a => "eval", :b => "...ruby code to be executed..." }
+  foo.send(params[:a], params[:b])
+
+When dispatching a method call based on user input, carefully verify that the
+method name. If possible, check it against a whitelist of safe method names.
+
+Note that the use of +public_send+ is also dangerous, as +send+ itself is
+public:
+
+  1.public_send("send", "eval", "...ruby code to be executed...")
+
+== DRb
+
+As DRb allows remote clients to invoke arbitrary methods, it is not suitable to
+expose to untrusted clients.
+
+When using DRb, try to avoid exposing it over the network if possible. If this
+isn't possible and you need to expose DRb to the world, you *must* configure an
+appropriate security policy with <code>DRb::ACL</code>.

-=begin
-
-= What's shell.rb?
-
-It realizes a wish to do execution of commands with filters and pipes
-like sh/csh by using just native facilities of ruby.
-
-= Main classes
-
-== Shell
-
-Every shell object has its own current working directory, and executes
-each command as if it stands in the directory.
-
---- Shell#cwd
---- Shell#dir
---- Shell#getwd
---- Shell#pwd
-
-      Returns the current directory
-
---- Shell#system_path
-
-      Returns the command search path in an array
-
---- Shell#umask
-
-      Returns the umask
-
-== Filter
-
-Any result of command exection is a Filter.  Filter include
-Enumerable, therefore a Filter object can use all Enumerable
-facilities.
-
-= Main methods
-
-== Command definitions
-
-In order to execute a command on your OS, you need to define it as a
-Shell method.
-
-Alternatively, you can execute any command via Shell#system even if it
-is not defined.
-
---- Shell.def_system_command(command, path = command)
-
-      Defines a command.  Registers <path> as a Shell method
-      <command>.
-
-      ex)
-      Shell.def_system_command "ls"
-        Defines ls.
-
-      Shell.def_system_command "sys_sort", "sort"
-        Defines sys_sort as sort.
-
---- Shell.undef_system_command(command)
-
-      Undefines a commmand
-
---- Shell.alias_command(ali, command, *opts) {...}
-
-      Aliases a command.
-
-      ex)
-        Shell.alias_command "lsC", "ls", "-CBF", "--show-control-chars"
-        Shell.alias_command("lsC", "ls"){|*opts| ["-CBF", "--show-control-chars", *opts]}
-
---- Shell.unalias_command(ali)
-
-      Unaliases a command.
-
---- Shell.install_system_commands(pre = "sys_")
-
-      Defines all commands in the default_system_path as Shell method,
-      all with <pre> prefixed to their names.
-
-== Creation
-
---- Shell.new
-
-      Creates a Shell object which current directory is set to the
-      process current directory.
-
---- Shell.cd(path)
-
-      Creates a Shell object which current directory is set to
-      <path>.

-      it restores the current directory when the block ends.
-
---- Shell#pushd(path = nil, &block)
---- Shell#pushdir
-
-      Pushes the current directory to the directory stack, changing
-      the current directory to <path>.  If <path> is omitted, it
-      exchanges its current directory and the top of its directory
-      stack.  If a block is given, it restores the current directory
-      when the block ends.
-
---- Shell#popd
---- Shell#popdir
-
-      Pops a directory from the directory stack, and sets the current
-      directory to it.
-
-== File and directory operations
-
---- Shell#foreach(path = nil, &block)

---- Shell#mkdir(*path)
-
-      Same as Dir.mkdir (with multiple directories allowed)
-
---- Shell#rmdir(*path)
-
-      Same as Dir.rmdir (with multiple directories allowed)
-
-== Command execution
-
---- System#system(command, *opts)
-
-      Executes <command> with <opts>.

-
-== Internal commands
-
---- Shell#echo(*strings)
---- Shell#cat(*files)
---- Shell#glob(patten)
---- Shell#tee(file)
-
-      Return Filter objects, which are results of their execution.
-
---- Filter#each &block
-
-      Iterates a block for each line of it.
-
---- Filter#<(src)
-
-      Inputs from <src>, which is either a string of a file name or an
-      IO.
-
---- Filter#>(to)
-
-      Outputs to <to>, which is either a string of a file name or an
-      IO.
-
---- Filter#>>(to)
-
-      Appends the ouput to <to>, which is either a string of a file
-      name or an IO.
-
---- Filter#|(filter)
-
-      Processes a pipeline.
-
---- Filter#+(filter)
-
-      (filter1 + filter2) outputs filter1, and then outputs filter2.

+= Caveats for implementing Signal.trap callbacks
+
+As with implementing signal handlers in C or most other languages,
+all code passed to Signal.trap must be reentrant.  If you are not
+familiar with reentrancy, you need to read up on it at
+{Wikipedia}[https://en.wikipedia.org/wiki/Reentrancy_(computing)] or
+elsewhere before reading the rest of this document.
+
+Most importantly, "thread-safety" does not guarantee reentrancy;
+and methods such as Mutex#lock and Mutex#synchronize which are
+commonly used for thread-safety even prevent reentrancy.
+
+== An implementation detail of the Ruby VM
+
+The Ruby VM defers Signal.trap callbacks from running until it is safe
+for its internal data structures, but it does not know when it is safe
+for data structures in YOUR code.  Ruby implements deferred signal
+handling by registering short C functions with only
+{async-signal-safe functions}[http://man7.org/linux/man-pages/man7/signal-safety.7.html] as
+signal handlers.  These short C functions only do enough tell the VM to
+run callbacks registered via Signal.trap later in the main Ruby Thread.
+
+== Unsafe methods to call in Signal.trap blocks
+
+When in doubt, consider anything not listed as safe below as being
+unsafe.
+
+* Mutex#lock, Mutex#synchronize and any code using them are explicitly
+  unsafe.  This includes Monitor in the standard library which uses
+  Mutex to provide reentrancy.
+
+* Dir.chdir with block
+
+* any IO write operations when IO#sync is false;
+  including IO#write, IO#write_nonblock, IO#puts.
+  Pipes and sockets default to `IO#sync = true', so it is safe to
+  write to them unless IO#sync was disabled.
+
+* File#flock, as the underlying flock(2) call is not specified by POSIX
+
+== Commonly safe operations inside Signal.trap blocks
+
+* Assignment and retrieval of local, instance, and class variables
+
+* Most object allocations and initializations of common types
+  including Array, Hash, String, Struct, Time.
+
+* Common Array, Hash, String, Struct operations which do not execute a block
+  are generally safe; but beware if iteration is occurring elsewhere.
+
+* Hash#[], Hash#[]= (unless Hash.new was given an unsafe block)
+
+* Thread::Queue#push and Thread::SizedQueue#push (since Ruby 2.1)
+
+* Creating a new Thread via Thread.new/Thread.start can used to get
+  around the unusability of Mutexes inside a signal handler
+
+* Signal.trap is safe to use inside blocks passed to Signal.trap
+
+* arithmetic on Integer and Float (`+', `-', '%', '*', '/')
+
+  Additionally, signal handlers do not run between two successive
+  local variable accesses, so shortcuts such as `+=' and `-=' will
+  not trigger a data race when used on Integer and Float classes in
+  signal handlers.
+
+== System call wrapper methods which are safe inside Signal.trap
+
+Since Ruby has wrappers around many
+{async-signal-safe C functions}[http://man7.org/linux/man-pages/man7/signal-safety.7.html]
+the corresponding wrappers for many IO, File, Dir, and Socket methods
+are safe.
+
+(Incomplete list)
+
+* Dir.chdir (without block arg)
+* Dir.mkdir
+* Dir.open
+* File#truncate
+* File.link
+* File.open
+* File.readlink
+* File.rename
+* File.stat
+* File.symlink
+* File.truncate
+* File.unlink
+* File.utime
+* IO#close
+* IO#dup
+* IO#fsync
+* IO#read
+* IO#read_nonblock
+* IO#stat
+* IO#sysread
+* IO#syswrite
+* IO.select
+* IO.pipe
+* Process.clock_gettime
+* Process.exit!
+* Process.fork
+* Process.kill
+* Process.pid
+* Process.ppid
+* Process.waitpid

+Each of these methods takes optional argument +format+,
+which has zero or more embedded _format_ _specifications_ (see below).
+
+Each of these methods returns the string resulting from replacing each
+format specification embedded in +format+ with a string form
+of one or more parts of the date or time.
+
+A simple example:
+
+  Time.now.strftime('%H:%M:%S') # => "14:02:07"
+
+A format specification has the form:
+
+  %[flags][width]conversion
+
+It consists of:
+
+- A leading percent character.
+- Zero or more _flags_ (each is a character).
+- An optional _width_ _specifier_ (an integer).
+- A _conversion_ _specifier_ (a character).
+
+Except for the leading percent character,
+the only required part is the conversion specifier, so we begin with that.

+=== Flags
+
+Flags may affect certain formatting specifications.
+
+Multiple flags may be given with a single conversion specified;
+order does not matter.
+
+==== Padding Flags
+
+- <tt>0</tt> - Pad with zeroes:
+
+    Time.new(10).strftime('%0Y') # => "0010"
+
+- <tt>_</tt> - Pad with blanks:

+
+- <tt>-</tt> - Don't pad:
+
+    Time.new(10).strftime('%-Y') # => "10"
+
+==== Casing Flags
+
+- <tt>^</tt> - Upcase result:
+
+    Time.new(2022, 1).strftime('%B')  # => "January" # No casing flag.
+    Time.new(2022, 1).strftime('%^B') # => "JANUARY"
+
+- <tt>#</tt> - Swapcase result:
+
+    Time.now.strftime('%p')  # => "AM"

+
+    Time.now.strftime('%:z')  # => "-05:00"
+
+- <tt>::</tt> - Put timezone as colon-separated hours, minutes, and seconds:
+
+    Time.now.strftime('%::z') # => "-05:00:00"
+
+=== Width Specifiers
+
+The integer width specifier gives a minimum width for the returned string:
+
+  Time.new(2002).strftime('%Y')       # => "2002"     # No width specifier.
+  Time.new(2002).strftime('%10Y')     # => "0000002002"

+== Specialized Format Strings
+
+Here are a few specialized format strings,
+each based on an external standard.
+
+=== HTTP Format
+
+The HTTP date format is based on
+{RFC 2616}[https://datatracker.ietf.org/doc/html/rfc2616],
+and treats dates in the format <tt>'%a, %d %b %Y %T GMT'</tt>:
+
+  d = Date.new(2001, 2, 3) # => #<Date: 2001-02-03>
+  # Return HTTP-formatted string.
+  httpdate = d.httpdate    # => "Sat, 03 Feb 2001 00:00:00 GMT"

+  # => {:wday=>6, :mday=>3, :mon=>2, :year=>2001, :hour=>0, :min=>0, :sec=>0, :zone=>"GMT", :offset=>0}
+
+=== RFC 3339 Format
+
+The RFC 3339 date format is based on

+
+=== RFC 2822 Format
+
+The RFC 2822 date format is based on
+{RFC 2822}[https://datatracker.ietf.org/doc/html/rfc2822],
+and treats dates in the format <tt>'%a, %-d %b %Y %T %z'</tt>]:
+

+  # => {:wday=>6, :mday=>3, :mon=>2, :year=>2001, :hour=>0, :min=>0, :sec=>0, :zone=>"+0000", :offset=>0}
+
+=== JIS X 0301 Format
+
+The JIS X 0301 format includes the
+{Japanese era name}[https://en.wikipedia.org/wiki/Japanese_era_name],
+and treats dates in the format <tt>'%Y-%m-%d'</tt>
+with the first letter of the romanized era name prefixed:
+
+  d = Date.new(2001, 2, 3) # => #<Date: 2001-02-03>
+  # Return 0301-formatted string.
+  jisx0301 = d.jisx0301    # => "H13.02.03"
+  # Return new date parsed from 0301-formatted string.
+  Date.jisx0301(jisx0301)  # => #<Date: 2001-02-03>
+  # Return hash parsed from 0301-formatted string.
+  Date._jisx0301(jisx0301) # => {:year=>2001, :mon=>2, :mday=>3}
+

+= Assignment
+
+In Ruby, assignment uses the <code>=</code> (equals sign) character.  This
+example assigns the number five to the local variable +v+:
+
+  v = 5
+
+Assignment creates a local variable if the variable was not previously
+referenced.
+
+An assignment expression result is always the assigned value, including
+{assignment methods}[rdoc-ref:syntax/assignment.rdoc@Assignment+Methods].
+
+== Local Variable Names
+
+A local variable name must start with a lowercase US-ASCII letter or a
+character with the eight bit set.  Typically local variables are US-ASCII
+compatible since the keys to type them exist on all keyboards.
+
+(Ruby programs must be written in a US-ASCII-compatible character set.  In
+such character sets if the eight bit is set it indicates an extended
+character.  Ruby allows local variables to contain such characters.)
+
+A local variable name may contain letters, numbers, an <code>_</code>
+(underscore or low line) or a character with the eighth bit set.
+
+== Local Variable Scope
+
+Once a local variable name has been assigned-to all uses of the name for the
+rest of the scope are considered local variables.
+
+Here is an example:
+
+  1.times do
+    a = 1
+    puts "local variables in the block: #{local_variables.join ", "}"
+  end
+
+  puts "no local variables outside the block" if local_variables.empty?
+
+This prints:
+
+  local variables in the block: a
+  no local variables outside the block
+
+Since the block creates a new scope, any local variables created inside it do
+not leak to the surrounding scope.
+
+Variables defined in an outer scope appear inner scope:
+
+  a = 0
+
+  1.times do
+    puts "local variables: #{local_variables.join ", "}"
+  end
+
+This prints:
+
+  local variables: a
+
+You may isolate variables in a block from the outer scope by listing them
+following a <code>;</code> in the block's arguments.  See the documentation
+for block local variables in the {calling
+methods}[rdoc-ref:syntax/calling_methods.rdoc] documentation for an example.
+
+See also Kernel#local_variables, but note that a +for+ loop does not create a
+new scope like a block does.
+
+== Local Variables and Methods
+
+In Ruby local variable names and method names are nearly identical.  If you
+have not assigned to one of these ambiguous names ruby will assume you wish to
+call a method.  Once you have assigned to the name ruby will assume you wish
+to reference a local variable.
+
+The local variable is created when the parser encounters the assignment, not
+when the assignment occurs:
+
+  a = 0 if false # does not assign to a
+
+  p local_variables # prints [:a]
+
+  p a # prints nil
+
+The similarity between method and local variable names can lead to confusing
+code, for example:
+
+  def big_calculation
+    42 # pretend this takes a long time
+  end
+
+  big_calculation = big_calculation()
+
+Now any reference to +big_calculation+ is considered a local variable and will
+be cached.  To call the method, use <code>self.big_calculation</code>.
+
+You can force a method call by using empty argument parentheses as shown above
+or by using an explicit receiver like <code>self</code>.  Using an explicit
+receiver may raise a NameError if the method's visibility is not public or the
+receiver is the literal <code>self</code>.
+
+Another commonly confusing case is when using a modifier +if+:
+
+  p a if a = 0.zero?
+
+Rather than printing "true" you receive a NameError, "undefined local variable
+or method `a'".  Since ruby parses the bare +a+ left of the +if+ first and has
+not yet seen an assignment to +a+ it assumes you wish to call a method.  Ruby
+then sees the assignment to +a+ and will assume you are referencing a local
+method.
+
+The confusion comes from the out-of-order execution of the expression.  First
+the local variable is assigned-to then you attempt to call a nonexistent
+method.
+
+== Local Variables and eval
+
+Using +eval+ to evaluate Ruby code will allow access to local variables defined
+in the same scope, even if the local variables are not defined until after the
+call to +eval+.  However, local variables defined inside the call to +eval+
+will not be reflected in the surrounding scope.  Inside the call to +eval+,
+local variables defined in the surrounding scope and local variables defined
+inside the call to +eval+ will be accessible.  However, you will not be able
+to access local variables defined in previous or subsequent calls to +eval+ in
+the same scope. Consider each +eval+ call a separate nested scope. Example:
+
+  def m
+    eval "bar = 1"
+    lvs = eval "baz = 2; ary = [local_variables, foo, baz]; x = 2; ary"
+    eval "quux = 3"
+    foo = 1
+    lvs << local_variables
+  end
+
+  m
+  # => [[:baz, :ary, :x, :lvs, :foo], nil, 2, [:lvs, :foo]]
+
+== Instance Variables
+
+Instance variables are shared across all methods for the same object.
+
+An instance variable must start with a <code>@</code> ("at" sign or
+commercial at).  Otherwise instance variable names follow the rules as local
+variable names.  Since the instance variable starts with an <code>@</code> the
+second character may be an upper-case letter.
+
+Here is an example of instance variable usage:
+
+  class C
+    def initialize(value)
+      @instance_variable = value
+    end
+
+    def value
+      @instance_variable
+    end
+  end
+
+  object1 = C.new "some value"
+  object2 = C.new "other value"
+
+  p object1.value # prints "some value"
+  p object2.value # prints "other value"
+
+An uninitialized instance variable has a value of +nil+.  If you run Ruby with
+warnings enabled, you will get a warning when accessing an uninitialized
+instance variable.
+
+The +value+ method has access to the value set by the +initialize+ method, but
+only for the same object.
+
+== Class Variables
+
+Class variables are shared between a class, its subclasses and its instances.
+
+A class variable must start with a <code>@@</code> (two "at" signs).  The rest
+of the name follows the same rules as instance variables.
+
+Here is an example:
+
+  class A
+    @@class_variable = 0
+
+    def value
+      @@class_variable
+    end
+
+    def update
+      @@class_variable = @@class_variable + 1
+    end
+  end
+
+  class B < A
+    def update
+      @@class_variable = @@class_variable + 2
+    end
+  end
+
+  a = A.new
+  b = B.new
+
+  puts "A value: #{a.value}"
+  puts "B value: #{b.value}"
+
+This prints:
+
+  A value: 0
+  B value: 0
+
+Continuing with the same example, we can update using objects from either
+class and the value is shared:
+
+  puts "update A"
+  a.update
+
+  puts "A value: #{a.value}"
+  puts "B value: #{b.value}"
+
+  puts "update B"
+  b.update
+
+  puts "A value: #{a.value}"
+  puts "B value: #{b.value}"
+
+  puts "update A"
+  a.update
+
+  puts "A value: #{a.value}"
+  puts "B value: #{b.value}"
+
+This prints:
+
+  update A
+  A value: 1
+  B value: 1
+  update B
+  A value: 3
+  B value: 3
+  update A
+  A value: 4
+  B value: 4
+
+Accessing an uninitialized class variable will raise a NameError exception.
+
+Note that classes have instance variables because classes are objects, so
+try not to confuse class and instance variables.
+
+== Global Variables
+
+Global variables are accessible everywhere.
+
+Global variables start with a <code>$</code> (dollar sign).  The rest of the
+name follows the same rules as instance variables.
+
+Here is an example:
+
+  $global = 0
+
+  class C
+    puts "in a class: #{$global}"
+
+    def my_method
+      puts "in a method: #{$global}"
+
+      $global = $global + 1
+      $other_global = 3
+    end
+  end
+
+  C.new.my_method
+
+  puts "at top-level, $global: #{$global}, $other_global: #{$other_global}"
+
+This prints:
+
+  in a class: 0
+  in a method: 0
+  at top-level, $global: 1, $other_global: 3
+
+An uninitialized global variable has a value of +nil+.
+
+Ruby has some special globals that behave differently depending on context
+such as the regular expression match variables or that have a side-effect when
+assigned to.  See the {global variables documentation}[rdoc-ref:globals.rdoc]
+for details.
+
+== Assignment Methods
+
+You can define methods that will behave like assignment, for example:
+
+  class C
+    def value=(value)
+      @value = value
+    end
+  end
+
+  c = C.new
+  c.value = 42
+
+Using assignment methods allows your programs to look nicer.  When assigning
+to an instance variable most people use Module#attr_accessor:
+
+  class C
+    attr_accessor :value
+  end
+
+When using method assignment you must always have a receiver.  If you do not
+have a receiver, Ruby assumes you are assigning to a local variable:
+
+  class C
+    attr_accessor :value
+
+    def my_method
+      value = 42
+
+      puts "local_variables: #{local_variables.join ", "}"
+      puts "@value: #{@value.inspect}"
+    end
+  end
+
+  C.new.my_method
+
+This prints:
+
+  local_variables: value
+  @value: nil
+
+To use the assignment method you must set the receiver:
+
+  class C
+    attr_accessor :value
+
+    def my_method
+      self.value = 42
+
+      puts "local_variables: #{local_variables.join ", "}"
+      puts "@value: #{@value.inspect}"
+    end
+  end
+
+  C.new.my_method
+
+This prints:
+
+  local_variables:
+  @value: 42
+
+Note that the value returned by an assignment method is ignored whatever,
+since an assignment expression result is always the assignment value.
+
+== Abbreviated Assignment
+
+You can mix several of the operators and assignment.  To add 1 to an object
+you can write:
+
+  a = 1
+
+  a += 2
+
+  p a # prints 3
+
+This is equivalent to:
+
+  a = 1
+
+  a = a + 2
+
+  p a # prints 3
+
+You can use the following operators this way:  <code>+</code>, <code>-</code>,
+<code>*</code>, <code>/</code>, <code>%</code>, <code>**</code>,
+<code>&</code>, <code>|</code>, <code>^</code>, <code><<</code>,
+<code>>></code>
+
+There are also <code>||=</code> and <code>&&=</code>.  The former makes an
+assignment if the value was +nil+ or +false+ while the latter makes an
+assignment if the value was not +nil+ or +false+.
+
+Here is an example:
+
+  a ||= 0
+  a &&= 1
+
+  p a # prints 1
+
+Note that these two operators behave more like <code>a || a = 0</code> than
+<code>a = a || 0</code>.
+
+== Implicit Array Assignment
+
+You can implicitly create an array by listing multiple values when assigning:
+
+  a = 1, 2, 3
+
+  p a # prints [1, 2, 3]
+
+This implicitly creates an Array.
+
+You can use <code>*</code> or the "splat" operator or unpack an Array when
+assigning.  This is similar to multiple assignment:
+
+  a = *[1, 2, 3]
+
+  p a # prints [1, 2, 3]
+
+You can splat anywhere in the right-hand side of the assignment:
+
+  a = 1, *[2, 3]
+
+  p a # prints [1, 2, 3]
+
+== Multiple Assignment
+
+You can assign multiple values on the right-hand side to multiple variables:
+
+  a, b = 1, 2
+
+  p a: a, b: b # prints {:a=>1, :b=>2}
+
+In the following sections any place "variable" is used an assignment method,
+instance, class or global will also work:
+
+  def value=(value)
+    p assigned: value
+  end
+
+  self.value, $global = 1, 2 # prints {:assigned=>1}
+
+  p $global # prints 2
+
+You can use multiple assignment to swap two values in-place:
+
+  old_value = 1
+
+  new_value, old_value = old_value, 2
+
+  p new_value: new_value, old_value: old_value
+  # prints {:new_value=>1, :old_value=>2}
+
+If you have more values on the right hand side of the assignment than variables
+on the left hand side, the extra values are ignored:
+
+  a, b = 1, 2, 3
+
+  p a: a, b: b # prints {:a=>1, :b=>2}
+
+You can use <code>*</code> to gather extra values on the right-hand side of
+the assignment.
+
+  a, *b = 1, 2, 3
+
+  p a: a, b: b # prints {:a=>1, :b=>[2, 3]}
+
+The <code>*</code> can appear anywhere on the left-hand side:
+
+  *a, b = 1, 2, 3
+
+  p a: a, b: b # prints {:a=>[1, 2], :b=>3}
+
+But you may only use one <code>*</code> in an assignment.
+
+== Array Decomposition
+
+Like Array decomposition in {method arguments}[rdoc-ref:syntax/methods.rdoc]
+you can decompose an Array during assignment using parenthesis:
+
+  (a, b) = [1, 2]
+
+  p a: a, b: b # prints {:a=>1, :b=>2}
+
+You can decompose an Array as part of a larger multiple assignment:
+
+  a, (b, c) = 1, [2, 3]
+
+  p a: a, b: b, c: c # prints {:a=>1, :b=>2, :c=>3}
+
+Since each decomposition is considered its own multiple assignment you can use
+<code>*</code> to gather arguments in the decomposition:
+
+  a, (b, *c), *d = 1, [2, 3, 4], 5, 6
+
+  p a: a, b: b, c: c, d: d
+  # prints {:a=>1, :b=>2, :c=>[3, 4], :d=>[5, 6]}

+= Calling Methods
+
+Calling a method sends a message to an object so it can perform some work.
+
+In ruby you send a message to an object like this:
+
+  my_method()
+
+Note that the parenthesis are optional:
+
+  my_method
+
+Except when there is difference between using and omitting parentheses, this
+document uses parenthesis when arguments are present to avoid confusion.
+
+This section only covers calling methods.  See also the {syntax documentation
+on defining methods}[rdoc-ref:syntax/methods.rdoc].
+
+== Receiver
+
++self+ is the default receiver.  If you don't specify any receiver +self+ will
+be used.  To specify a receiver use <code>.</code>:
+
+  my_object.my_method
+
+This sends the +my_method+ message to +my_object+.  Any object can be a
+receiver but depending on the method's visibility sending a message may raise a
+NoMethodError.
+
+You may also use <code>::</code> to designate a receiver, but this is rarely
+used due to the potential for confusion with <code>::</code> for namespaces.
+
+=== Chaining \Method Calls
+
+You can "chain" method calls by immediately following one method call with another.
+
+This example chains methods Array#append and Array#compact:
+
+  a = [:foo, 'bar', 2]
+  a1 = [:baz, nil, :bam, nil]
+  a2 = a.append(*a1).compact
+  a2 # => [:foo, "bar", 2, :baz, :bam]
+
+Details:
+
+- First method <tt>merge</tt> creates a copy of <tt>a</tt>,
+  appends (separately) each element of <tt>a1</tt> to the copy, and returns
+    [:foo, "bar", 2, :baz, nil, :bam, nil]
+- Chained method <tt>compact</tt> creates a copy of that return value,
+  removes its <tt>nil</tt>-valued entries, and returns
+     [:foo, "bar", 2, :baz, :bam]
+
+You can chain methods that are in different classes.
+This example chains methods Hash#to_a and Array#reverse:
+
+  h = {foo: 0, bar: 1, baz: 2}
+  h.to_a.reverse # => [[:baz, 2], [:bar, 1], [:foo, 0]]
+
+Details:
+
+- First method Hash#to_a converts <tt>a</tt> to an \Array, and returns
+    [[:foo, 0], [:bar, 1], [:baz, 2]]
+- Chained method Array#reverse creates copy of that return value,
+  reverses it, and  returns
+    [[:baz, 2], [:bar, 1], [:foo, 0]]
+
+=== Safe Navigation Operator
+
+<code>&.</code>, called "safe navigation operator", allows to skip method call
+when receiver is +nil+. It returns +nil+ and doesn't evaluate method's arguments
+if the call is skipped.
+
+  REGEX = /(ruby) is (\w+)/i
+  "Ruby is awesome!".match(REGEX).values_at(1, 2)
+  # => ["Ruby", "awesome"]
+  "Python is fascinating!".match(REGEX).values_at(1, 2)
+  # NoMethodError: undefined method `values_at' for nil:NilClass
+  "Python is fascinating!".match(REGEX)&.values_at(1, 2)
+  # => nil
+
+This allows to easily chain methods which could return empty value. Note that
+<code>&.</code> skips only one next call, so for a longer chain it is necessary
+to add operator on each level:
+
+  "Python is fascinating!".match(REGEX)&.values_at(1, 2).join(' - ')
+  # NoMethodError: undefined method `join' for nil:NilClass
+  "Python is fascinating!".match(REGEX)&.values_at(1, 2)&.join(' - ')
+  # => nil
+
+== Arguments
+
+There are three types of arguments when sending a message, the positional
+arguments, keyword (or named) arguments and the block argument.  Each message
+sent may use one, two or all types of arguments, but the arguments must be
+supplied in this order.
+
+All arguments in ruby are passed by reference and are not lazily evaluated.
+
+Each argument is separated by a <code>,</code>:
+
+  my_method(1, '2', :three)
+
+Arguments may be an expression, a hash argument:
+
+  'key' => value
+
+or a keyword argument:
+
+  key: value
+
+Hash and keyword arguments must be contiguous and must appear after all
+positional arguments, but may be mixed:
+
+  my_method('a' => 1, b: 2, 'c' => 3)
+
+=== Positional Arguments
+
+The positional arguments for the message follow the method name:
+
+  my_method(argument1, argument2)
+
+In many cases, parenthesis are not necessary when sending a message:
+
+  my_method argument1, argument2
+
+However, parenthesis are necessary to avoid ambiguity.  This will raise a
+SyntaxError because ruby does not know which method argument3 should be sent
+to:
+
+  method_one argument1, method_two argument2, argument3
+
+If the method definition has a <code>*argument</code> extra positional
+arguments will be assigned to +argument+ in the method as an Array.
+
+If the method definition doesn't include keyword arguments, the keyword or
+hash-type arguments are assigned as a single hash to the last argument:
+
+  def my_method(options)
+    p options
+  end
+
+  my_method('a' => 1, b: 2) # prints: {'a'=>1, :b=>2}
+
+If too many positional arguments are given, an ArgumentError is raised.
+
+=== Default Positional Arguments
+
+When the method defines default arguments you do not need to supply all the
+arguments to the method.  Ruby will fill in the missing arguments in-order.
+
+First we'll cover the simple case where the default arguments appear on the
+right.  Consider this method:
+
+  def my_method(a, b, c = 3, d = 4)
+    p [a, b, c, d]
+  end
+
+Here +c+ and +d+ have default values which ruby will apply for you.  If you
+send only two arguments to this method:
+
+  my_method(1, 2)
+
+You will see ruby print <code>[1, 2, 3, 4]</code>.
+
+If you send three arguments:
+
+  my_method(1, 2, 5)
+
+You will see ruby print <code>[1, 2, 5, 4]</code>
+
+Ruby fills in the missing arguments from left to right.
+
+Ruby allows default values to appear in the middle of positional arguments.
+Consider this more complicated method:
+
+  def my_method(a, b = 2, c = 3, d)
+    p [a, b, c, d]
+  end
+
+Here +b+ and +c+ have default values.  If you send only two arguments to this
+method:
+
+  my_method(1, 4)
+
+You will see ruby print <code>[1, 2, 3, 4]</code>.
+
+If you send three arguments:
+
+  my_method(1, 5, 6)
+
+You will see ruby print <code>[1, 5, 3, 6]</code>.
+
+Describing this in words gets complicated and confusing. I'll describe it
+in variables and values instead.
+
+First <code>1</code> is assigned to +a+, then <code>6</code> is assigned to
++d+.  This leaves only the arguments with default values.  Since
+<code>5</code> has not been assigned to a value yet, it is given to +b+ and
++c+ uses its default value of <code>3</code>.
+
+=== Keyword Arguments
+
+Keyword arguments follow any positional arguments and are separated by commas
+like positional arguments:
+
+  my_method(positional1, keyword1: value1, keyword2: value2)
+
+Any keyword arguments not given will use the default value from the method
+definition.  If a keyword argument is given that the method did not list,
+and the method definition does not accept arbitrary keyword arguments, an
+ArgumentError will be raised.
+
+Keyword argument value can be omitted, meaning the value will be be fetched
+from the context by the name of the key
+
+  keyword1 = 'some value'
+  my_method(positional1, keyword1:)
+  # ...is the same as
+  my_method(positional1, keyword1: keyword1)
+
+Be aware that when method parenthesis are omitted, too, the parsing order might
+be unexpected:
+
+  my_method positional1, keyword1:
+
+  some_other_expression
+
+  # ...is actually parsed as
+  my_method(positional1, keyword1: some_other_expression)
+
+=== Block Argument
+
+The block argument sends a closure from the calling scope to the method.
+
+The block argument is always last when sending a message to a method.  A block
+is sent to a method using <code>do ... end</code> or <code>{ ... }</code>:
+
+  my_method do
+    # ...
+  end
+
+or:
+
+  my_method {
+    # ...
+  }
+
+<code>do end</code> has lower precedence than <code>{ }</code> so:
+
+  method_1 method_2 {
+    # ...
+  }
+
+Sends the block to +method_2+ while:
+
+  method_1 method_2 do
+    # ...
+  end
+
+Sends the block to +method_1+.  Note that in the first case if parentheses are
+used the block is sent to +method_1+.
+
+A block will accept arguments from the method it was sent to.  Arguments are
+defined similar to the way a method defines arguments.  The block's arguments
+go in <code>| ... |</code> following the opening <code>do</code> or
+<code>{</code>:
+
+  my_method do |argument1, argument2|
+    # ...
+  end
+
+==== Block Local Arguments
+
+You may also declare block-local arguments to a block using <code>;</code> in
+the block arguments list.  Assigning to a block-local argument will not
+override local arguments outside the block in the caller's scope:
+
+  def my_method
+    yield self
+  end
+
+  place = "world"
+
+  my_method do |obj; place|
+    place = "block"
+    puts "hello #{obj} this is #{place}"
+  end
+
+  puts "place is: #{place}"
+
+This prints:
+
+  hello main this is block
+  place is world
+
+So the +place+ variable in the block is not the same +place+ variable as
+outside the block.  Removing <code>; place</code> from the block arguments
+gives this result:
+
+  hello main this is block
+  place is block
+
+=== Array to Arguments Conversion
+
+Given the following method:
+
+  def my_method(argument1, argument2, argument3)
+  end
+
+You can turn an Array into an argument list with <code>*</code> (or splat)
+operator:
+
+  arguments = [1, 2, 3]
+  my_method(*arguments)
+
+or:
+
+  arguments = [2, 3]
+  my_method(1, *arguments)
+
+Both are equivalent to:
+
+  my_method(1, 2, 3)
+
+If the method accepts keyword arguments, the splat operator will convert a
+hash at the end of the array into keyword arguments:
+
+  def my_method(a, b, c: 3)
+  end
+
+  arguments = [1, 2, { c: 4 }]
+  my_method(*arguments)
+
+Note that this behavior is currently deprecated and will emit a warning.
+This behavior will be removed in Ruby 3.0.
+
+You may also use the <code>**</code> (described next) to convert a Hash into
+keyword arguments.
+
+If the number of objects in the Array do not match the number of arguments for
+the method, an ArgumentError will be raised.
+
+If the splat operator comes first in the call, parentheses must be used to
+avoid a warning:
+
+  my_method *arguments  # warning
+  my_method(*arguments) # no warning
+
+=== Hash to Keyword Arguments Conversion
+
+Given the following method:
+
+  def my_method(first: 1, second: 2, third: 3)
+  end
+
+You can turn a Hash into keyword arguments with the <code>**</code>
+(keyword splat) operator:
+
+  arguments = { first: 3, second: 4, third: 5 }
+  my_method(**arguments)
+
+or:
+
+  arguments = { first: 3, second: 4 }
+  my_method(third: 5, **arguments)
+
+Both are equivalent to:
+
+  my_method(first: 3, second: 4, third: 5)
+
+If the method definition uses the keyword splat operator to
+gather arbitrary keyword arguments, they will not be gathered
+by <code>*</code>:
+
+  def my_method(*a, **kw)
+    p arguments: a, keywords: kw
+  end
+
+  my_method(1, 2, '3' => 4, five: 6)
+
+Prints:
+
+  {:arguments=>[1, 2], :keywords=>{'3'=>4, :five=>6}}
+
+=== Proc to Block Conversion
+
+Given a method that use a block:
+
+  def my_method
+    yield self
+  end
+
+You can convert a proc or lambda to a block argument with the <code>&</code>
+(block conversion) operator:
+
+  argument = proc { |a| puts "#{a.inspect} was yielded" }
+
+  my_method(&argument)
+
+If the block conversion operator comes first in the call, parenthesis must be
+used to avoid a warning:
+
+  my_method &argument  # warning
+  my_method(&argument) # no warning
+
+== Method Lookup
+
+When you send a message, Ruby looks up the method that matches the name of the
+message for the receiver.  Methods are stored in classes and modules so method
+lookup walks these, not the objects themselves.
+
+Here is the order of method lookup for the receiver's class or module +R+:
+
+* The prepended modules of +R+ in reverse order
+* For a matching method in +R+
+* The included modules of +R+ in reverse order
+
+If +R+ is a class with a superclass, this is repeated with +R+'s superclass
+until a method is found.
+
+Once a match is found method lookup stops.
+
+If no match is found this repeats from the beginning, but looking for
++method_missing+.  The default +method_missing+ is BasicObject#method_missing
+which raises a NameError when invoked.
+
+If refinements (an experimental feature) are active, the method lookup changes.
+See the {refinements documentation}[rdoc-ref:syntax/refinements.rdoc] for
+details.

+= Code Comments
+
+Ruby has two types of comments: inline and block.
+
+Inline comments start with the <code>#</code> character and continue until the
+end of the line:
+
+  # On a separate line
+  class Foo # or at the end of the line
+    # can be indented
+    def bar
+    end
+  end
+
+Block comments start with <code>=begin</code> and end with <code>=end</code>.
+Each should start on a separate line.

+  This is
+  commented out
+  =end
+
+  class Foo
+  end
+
+  =begin some_tag
+  this works, too
+  =end
+
+<code>=begin</code> and <code>=end</code> can not be indented, so this is a
+syntax error:
+
+  class Foo
+    =begin
+    Will not work
+    =end
+  end
+
+== Magic Comments
+
+While comments are typically ignored by Ruby, special "magic comments" contain
+directives that affect how the code is interpreted.
+
+Top-level magic comments must appear in the first comment section of a file.
+
+NOTE: Magic comments affect only the file in which they appear;
+other files are unaffected.
+
+  # frozen_string_literal: true
+
+  var = 'hello'
+  var.frozen? # => true
+
+=== Alternative syntax
+
+Magic comments may consist of a single directive (as in the example above).
+Alternatively, multiple directives may appear on the same line if separated by ";"
+and wrapped between "-*-" (see Emacs' {file variables}[https://www.gnu.org/software/emacs/manual/html_node/emacs/Specifying-File-Variables.html]).
+
+  # emacs-compatible; -*- coding: big5; mode: ruby; frozen_string_literal: true -*-
+
+  p 'hello'.frozen? # => true
+  p 'hello'.encoding # => #<Encoding:Big5>
+
+=== +encoding+ Directive
+
+Indicates which string encoding should be used for string literals,
+regexp literals and <code>__ENCODING__</code>:
+
+  # encoding: big5
+
+  ''.encoding # => #<Encoding:Big5>
+
+Default encoding is UTF-8.
+
+Top-level magic comments must start on the first line, or on the second line if
+the first line looks like <tt>#! shebang line</tt>.
+
+The word "coding" may be used instead of "encoding".
+
+=== +frozen_string_literal+ Directive
+
+Indicates that string literals should be allocated once at parse time and frozen.
+
+  # frozen_string_literal: true
+
+  3.times do
+    p 'hello'.object_id # => prints same number
+  end
+  p 'world'.frozen? # => true
+
+The default is false; this can be changed with <code>--enable=frozen-string-literal</code>.
+Without the directive, or with <code># frozen_string_literal: false</code>,
+the example above would print 3 different numbers and "false".
+
+Starting in Ruby 3.0, string literals that are dynamic are not frozen nor reused:
+
+  # frozen_string_literal: true
+
+  p "Addition: #{2 + 2}".frozen? # => false
+
+It must appear in the first comment section of a file.
+
+=== +warn_indent+ Directive
+
+This directive can turn on detection of bad indentation for statements that follow it:
+
+  def foo
+    end # => no warning
+
+  # warn_indent: true
+  def bar
+    end # => warning: mismatched indentations at 'end' with 'def' at 6
+
+Another way to get these warnings to show is by running Ruby with warnings (<code>ruby -w</code>). Using a directive to set this false will prevent these warnings to show.
+
+=== +shareable_constant_value+ Directive
+
+Note: This directive is experimental in Ruby 3.0 and may change in future releases.
+
+This special directive helps to create constants that hold only immutable objects, or {Ractor-shareable}[rdoc-ref:Ractor@Shareable+and+unshareable+objects] constants.
+
+The directive can specify special treatment for values assigned to constants:
+
+* +none+: (default)
+* +literal+: literals are implicitly frozen, others must be Ractor-shareable
+* +experimental_everything+: all made shareable
+* +experimental_copy+: copy deeply and make it shareable
+
+==== Mode +none+ (default)
+
+No special treatment in this mode (as in Ruby 2.x): no automatic freezing and no checks.
+
+It has always been a good idea to deep-freeze constants; Ractor makes this
+an even better idea as only the main ractor can access non-shareable constants:
+
+  # shareable_constant_value: none
+  A = {foo: []}
+  A.frozen? # => false
+  Ractor.new { puts A } # => can not access non-shareable objects by non-main Ractor.
+
+==== Mode +literal+
+
+In "literal" mode, constants assigned to literals will be deeply-frozen:
+
+  # shareable_constant_value: literal
+  X = [{foo: []}] # => same as [{foo: [].freeze}.freeze].freeze
+
+Other values must be shareable:
+
+  # shareable_constant_value: literal
+  X = Object.new # => cannot assign unshareable object to X
+
+Note that only literals directly assigned to constants, or recursively held in such literals will be frozen:
+
+  # shareable_constant_value: literal
+  var = [{foo: []}]
+  var.frozen? # => false (assignment was made to local variable)
+  X = var # => cannot assign unshareable object to X
+
+  X = Set[1, 2, {foo: []}].freeze # => cannot assign unshareable object to X
+                                  # (`Set[...]` is not a literal and
+                                  # `{foo: []}` is an argument to `Set.[]`)
+
+The method Module#const_set is not affected.
+
+==== Mode +experimental_everything+
+
+In this mode, all values assigned to constants are made shareable.
+
+  # shareable_constant_value: experimental_everything
+  FOO = Set[1, 2, {foo: []}]
+  # same as FOO = Ractor.make_sharable(...)
+  # OR same as `FOO = Set[1, 2, {foo: [].freeze}.freeze].freeze`
+
+  var = [{foo: []}]
+  var.frozen? # => false (assignment was made to local variable)
+  X = var # => calls `Ractor.make_shareable(var)`
+  var.frozen? # => true
+
+This mode is "experimental", because it might be error prone, for
+example by deep-freezing the constants of an external resource which
+could cause errors:
+
+  # shareable_constant_value: experimental_everything
+  FOO = SomeGem::Something::FOO
+  # => deep freezes the gem's constant!
+
+This will be revisited before Ruby 3.1 to either allow `everything`
+or to instead remove this mode.
+
+The method Module#const_set is not affected.
+
+==== Mode +experimental_copy+
+
+In this mode, all values assigned to constants are deeply copied and
+made shareable. It is safer mode than +experimental_everything+.
+
+  # shareable_constant_value: experimental_everything
+  var = [{foo: []}]
+  var.frozen? # => false (assignment was made to local variable)
+  X = var # => calls `Ractor.make_shareable(var, copy: true)`
+  var.frozen? # => false
+  Ractor.shareable?(X) #=> true
+  var.object_id == X.object_id #=> false
+
+This mode is "experimental" and has not been discussed thoroughly.
+This will be revisited before Ruby 3.1 to either allow `copy`
+or to instead remove this mode.
+
+The method Module#const_set is not affected.
+
+==== Scope
+
+This directive can be used multiple times in the same file:
+
+  # shareable_constant_value: none
+  A = {foo: []}
+  A.frozen? # => false
+  Ractor.new { puts A } # => can not access non-shareable objects by non-main Ractor.
+
+  # shareable_constant_value: literal
+  B = {foo: []}
+  B.frozen? # => true
+  B[:foo].frozen? # => true
+
+  C = [Object.new] # => cannot assign unshareable object to C (Ractor::IsolationError)
+
+  D = [Object.new.freeze]
+  D.frozen? # => true
+
+  # shareable_constant_value: experimental_everything
+  E = Set[1, 2, Object.new]
+  E.frozen? # => true
+  E.all(&:frozen?) # => true
+
+The directive affects only subsequent constants and only for the current scope:
+
+  module Mod
+    # shareable_constant_value: literal
+    A = [1, 2, 3]
+    module Sub
+      B = [4, 5]
+    end
+  end
+
+  C = [4, 5]
+
+  module Mod
+    D = [6]
+  end
+  p Mod::A.frozen?, Mod::Sub::B.frozen? # => true, true
+  p C.frozen?, Mod::D.frozen? # => false, false

+= Control Expressions
+
+Ruby has a variety of ways to control execution.  All the expressions described
+here return a value.
+
+For the tests in these control expressions, +nil+ and +false+ are false-values
+and +true+ and any other object are true-values.  In this document "true" will
+mean "true-value" and "false" will mean "false-value".
+
+== +if+ Expression
+
+The simplest +if+ expression has two parts, a "test" expression and a "then"
+expression.  If the "test" expression evaluates to a true then the "then"
+expression is evaluated.
+
+Here is a simple if statement:
+
+  if true then
+    puts "the test resulted in a true-value"
+  end
+
+This will print "the test resulted in a true-value".
+
+The +then+ is optional:
+
+  if true
+    puts "the test resulted in a true-value"
+  end
+
+This document will omit the optional +then+ for all expressions as that is the
+most common usage of +if+.
+
+You may also add an +else+ expression.  If the test does not evaluate to true
+the +else+ expression will be executed:
+
+  if false
+    puts "the test resulted in a true-value"
+  else
+    puts "the test resulted in a false-value"
+  end
+
+This will print "the test resulted in a false-value".
+
+You may add an arbitrary number of extra tests to an if expression using
++elsif+.  An +elsif+ executes when all tests above the +elsif+ are false.
+
+  a = 1
+
+  if a == 0
+    puts "a is zero"
+  elsif a == 1
+    puts "a is one"
+  else
+    puts "a is some other value"
+  end
+
+This will print "a is one" as <code>1</code> is not equal to <code>0</code>.
+Since +else+ is only executed when there are no matching conditions.
+
+Once a condition matches, either the +if+ condition or any +elsif+ condition,
+the +if+ expression is complete and no further tests will be performed.
+
+Like an +if+, an +elsif+ condition may be followed by a +then+.
+
+In this example only "a is one" is printed:
+
+  a = 1
+
+  if a == 0
+    puts "a is zero"
+  elsif a == 1
+    puts "a is one"
+  elsif a >= 1
+    puts "a is greater than or equal to one"
+  else
+    puts "a is some other value"
+  end
+
+The tests for +if+ and +elsif+ may have side-effects.  The most common use of
+side-effect is to cache a value into a local variable:
+
+  if a = object.some_value
+    # do something to a
+  end
+
+The result value of an +if+ expression is the last value executed in the
+expression.
+
+== Ternary if
+
+You may also write a if-then-else expression using <code>?</code> and
+<code>:</code>.  This ternary if:
+
+  input_type = gets =~ /hello/i ? "greeting" : "other"
+
+Is the same as this +if+ expression:
+
+  input_type =
+    if gets =~ /hello/i
+      "greeting"
+    else
+      "other"
+    end
+
+While the ternary if is much shorter to write than the more verbose form, for
+readability it is recommended that the ternary if is only used for simple
+conditionals.  Also, avoid using multiple ternary conditions in the same
+expression as this can be confusing.
+
+== +unless+ Expression
+
+The +unless+ expression is the opposite of the +if+ expression.  If the value
+is false, the "then" expression is executed:
+
+  unless true
+    puts "the value is a false-value"
+  end
+
+This prints nothing as true is not a false-value.
+
+You may use an optional +then+ with +unless+ just like +if+.
+
+Note that the above +unless+ expression is the same as:
+
+  if not true
+    puts "the value is a false-value"
+  end
+
+Like an +if+ expression you may use an +else+ condition with +unless+:
+
+  unless true
+    puts "the value is false"
+  else
+    puts "the value is true"
+  end
+
+This prints "the value is true" from the +else+ condition.
+
+You may not use +elsif+ with an +unless+ expression.
+
+The result value of an +unless+ expression is the last value executed in the
+expression.
+
+== Modifier +if+ and +unless+
+
++if+ and +unless+ can also be used to modify an expression.  When used as a
+modifier the left-hand side is the "then" statement and the right-hand side
+is the "test" expression:
+
+  a = 0
+
+  a += 1 if a.zero?
+
+  p a
+
+This will print 1.
+
+  a = 0
+
+  a += 1 unless a.zero?
+
+  p a
+
+This will print 0.
+
+While the modifier and standard versions have both a "test" expression and a
+"then" statement, they are not exact transformations of each other due to
+parse order.  Here is an example that shows the difference:
+
+  p a if a = 0.zero?
+
+This raises the NameError "undefined local variable or method `a'".
+
+When ruby parses this expression it first encounters +a+ as a method call in
+the "then" expression, then later it sees the assignment to +a+ in the "test"
+expression and marks +a+ as a local variable.
+
+When running this line it first executes the "test" expression, <code>a =
+0.zero?</code>.
+
+Since the test is true it executes the "then" expression, <code>p a</code>.
+Since the +a+ in the body was recorded as a method which does not exist the
+NameError is raised.
+
+The same is true for +unless+.
+
+== +case+ Expression
+
+The +case+ expression can be used in two ways.
+
+The most common way is to compare an object against multiple patterns.  The
+patterns are matched using the +===+ method which is aliased to +==+ on
+Object.  Other classes must override it to give meaningful behavior.  See
+Module#=== and Regexp#=== for examples.
+
+Here is an example of using +case+ to compare a String against a pattern:
+
+  case "12345"
+  when /^1/
+    puts "the string starts with one"
+  else
+    puts "I don't know what the string starts with"
+  end
+
+Here the string <code>"12345"</code> is compared with <code>/^1/</code> by
+calling <code>/^1/ === "12345"</code> which returns +true+.  Like the +if+
+expression, the first +when+ that matches is executed and all other matches are
+ignored.
+
+If no matches are found, the +else+ is executed.
+
+The +else+ and +then+ are optional, this +case+ expression gives the same
+result as the one above:
+
+  case "12345"
+  when /^1/
+    puts "the string starts with one"
+  end
+
+You may place multiple conditions on the same +when+:
+
+  case "2"
+  when /^1/, "2"
+    puts "the string starts with one or is '2'"
+  end
+
+Ruby will try each condition in turn, so first <code>/^1/ === "2"</code>
+returns +false+, then <code>"2" === "2"</code> returns +true+, so "the string
+starts with one or is '2'" is printed.
+
+You may use +then+ after the +when+ condition.  This is most frequently used
+to place the body of the +when+ on a single line.
+
+  case a
+  when 1, 2 then puts "a is one or two"
+  when 3    then puts "a is three"
+  else           puts "I don't know what a is"
+  end
+
+The other way to use a +case+ expression is like an if-elsif expression:
+
+  a = 2
+
+  case
+  when a == 1, a == 2
+    puts "a is one or two"
+  when a == 3
+    puts "a is three"
+  else
+    puts "I don't know what a is"
+  end
+
+Again, the +then+ and +else+ are optional.
+
+The result value of a +case+ expression is the last value executed in the
+expression.
+
+Since Ruby 2.7, +case+ expressions also provide a more powerful experimental
+pattern matching feature via the +in+ keyword:
+
+  case {a: 1, b: 2, c: 3}
+  in a: Integer => m
+    "matched: #{m}"
+  else
+    "not matched"
+  end
+  # => "matched: 1"
+
+The pattern matching syntax is described on
+{its own page}[rdoc-ref:syntax/pattern_matching.rdoc].
+
+== +while+ Loop
+
+The +while+ loop executes while a condition is true:
+
+  a = 0
+
+  while a < 10 do
+    p a
+    a += 1
+  end
+
+  p a
+
+Prints the numbers 0 through 10.  The condition <code>a < 10</code> is checked
+before the loop is entered, then the body executes, then the condition is
+checked again.  When the condition results in false the loop is terminated.
+
+The +do+ keyword is optional.  The following loop is equivalent to the loop
+above:
+
+  while a < 10
+    p a
+    a += 1
+  end
+
+The result of a +while+ loop is +nil+ unless +break+ is used to supply a
+value.
+
+== +until+ Loop
+
+The +until+ loop executes while a condition is false:
+
+  a = 0
+
+  until a > 10 do
+    p a
+    a += 1
+  end
+
+  p a
+
+This prints the numbers 0 through 11.  Like a while loop the condition <code>a
+> 10</code> is checked when entering the loop and each time the loop body
+executes.  If the condition is false the loop will continue to execute.
+
+Like a +while+ loop, the +do+ is optional.
+
+Like a +while+ loop, the result of an +until+ loop is nil unless +break+ is
+used.
+
+== +for+ Loop
+
+The +for+ loop consists of +for+ followed by a variable to contain the
+iteration argument followed by +in+ and the value to iterate over using #each.
+The +do+ is optional:
+
+  for value in [1, 2, 3] do
+    puts value
+  end
+
+Prints 1, 2 and 3.
+
+Like +while+ and +until+, the +do+ is optional.
+
+The +for+ loop is similar to using #each, but does not create a new variable
+scope.
+
+The result value of a +for+ loop is the value iterated over unless +break+ is
+used.
+
+The +for+ loop is rarely used in modern ruby programs.
+
+== Modifier +while+ and +until+
+
+Like +if+ and +unless+, +while+ and +until+ can be used as modifiers:
+
+  a = 0
+
+  a += 1 while a < 10
+
+  p a # prints 10
+
++until+ used as a modifier:
+
+  a = 0
+
+  a += 1 until a > 10
+
+  p a # prints 11
+
+You can use +begin+ and +end+ to create a +while+ loop that runs the body once
+before the condition:
+
+  a = 0
+
+  begin
+    a += 1
+  end while a < 10
+
+  p a # prints 10
+
+If you don't use +rescue+ or +ensure+, Ruby optimizes away any exception
+handling overhead.
+
+== +break+ Statement
+
+Use +break+ to leave a block early.  This will stop iterating over the items in +values+ if one of them is even:
+
+  values.each do |value|
+    break if value.even?
+
+    # ...
+  end
+
+You can also terminate from a +while+ loop using +break+:
+
+  a = 0
+
+  while true do
+    p a
+    a += 1
+
+    break if a < 10
+  end
+
+  p a
+
+This prints the numbers 0 and 1.
+
++break+ accepts a value that supplies the result of the expression it is
+"breaking" out of:
+
+  result = [1, 2, 3].each do |value|
+    break value * 2 if value.even?
+  end
+
+  p result # prints 4
+
+== +next+ Statement
+
+Use +next+ to skip the rest of the current iteration:
+
+  result = [1, 2, 3].map do |value|
+    next if value.even?
+
+    value * 2
+  end
+
+  p result # prints [2, nil, 6]
+
++next+ accepts an argument that can be used as the result of the current
+block iteration:
+
+  result = [1, 2, 3].map do |value|
+    next value if value.even?
+
+    value * 2
+  end
+
+  p result # prints [2, 2, 6]
+
+== +redo+ Statement
+
+Use +redo+ to redo the current iteration:
+
+  result = []
+
+  while result.length < 10 do
+    result << result.length
+
+    redo if result.last.even?
+
+    result << result.length + 1
+  end
+
+  p result
+
+This prints [0, 1, 3, 3, 5, 5, 7, 7, 9, 9, 11]
+
+In Ruby 1.8, you could also use +retry+ where you used +redo+.  This is no
+longer true, now you will receive a SyntaxError when you use +retry+ outside
+of a +rescue+ block.  See {Exceptions}[rdoc-ref:syntax/exceptions.rdoc]
+for proper usage of +retry+.
+
+== Modifier Statements
+
+Ruby's grammar differentiates between statements and expressions.  All
+expressions are statements (an expression is a type of statement), but
+not all statements are expressions.  Some parts of the grammar accept
+expressions and not other types of statements, which causes code that
+looks similar to be parsed differently.
+
+For example, when not used as a modifier, +if+, +else+, +while+, +until+,
+and +begin+ are expressions (and also statements).  However, when
+used as a modifier, +if+, +else+, +while+, +until+ and +rescue+
+are statements but not expressions.
+
+  if true; 1 end # expression (and therefore statement)
+  1 if true      # statement (not expression)
+
+Statements that are not expressions cannot be used in contexts where an
+expression is expected, such as method arguments.
+
+  puts( 1 if true )      #=> SyntaxError
+
+You can wrap a statement in parentheses to create an expression.
+
+  puts((1 if true))      #=> 1
+
+If you put a space between the method name and opening parenthesis, you
+do not need two sets of parentheses.
+
+  puts (1 if true)       #=> 1, because of optional parentheses for method
+
+This is because this is parsed similar to a method call without
+parentheses.  It is equivalent to the following code, without the creation
+of a local variable:
+
+  x = (1 if true)
+  p x
+
+In a modifier statement, the left-hand side must be a statement and the
+right-hand side must be an expression.
+
+So in <code>a if b rescue c</code>, because <code>b rescue c</code> is a
+statement that is not an expression, and therefore is not allowed as the
+right-hand side of the +if+ modifier statement, the code is necessarily
+parsed as <code>(a if b) rescue c</code>.
+
+This interacts with operator precedence in such a way that:
+
+  stmt if v = expr rescue x
+  stmt if v = expr unless x
+
+are parsed as:
+
+  stmt if v = (expr rescue x)
+  (stmt if v = expr) unless x
+
+This is because modifier +rescue+ has higher precedence than <code>=</code>,
+and modifier +if+ has lower precedence than <code>=</code>.
+
+== Flip-Flop
+
+The flip-flop is a slightly special conditional expression.  One of its
+typical uses is processing text from ruby one-line programs used with
+<code>ruby -n</code> or <code>ruby -p</code>.
+
+The form of the flip-flop is an expression that indicates when the
+flip-flop turns on, <code>..</code> (or <code>...</code>), then an expression
+that indicates when the flip-flop will turn off.  While the flip-flop is on it
+will continue to evaluate to +true+, and +false+ when off.
+
+Here is an example:
+
+  selected = []
+
+  0.upto 10 do |value|
+    selected << value if value==2..value==8
+  end
+
+  p selected # prints [2, 3, 4, 5, 6, 7, 8]
+
+In the above example, the `on' condition is <code>n==2</code>.  The flip-flop
+is initially `off' (false) for 0 and 1, but becomes `on' (true) for 2 and
+remains `on' through 8.  After 8 it turns off and remains `off' for 9 and 10.
+
+The flip-flop must be used inside a conditional such as <code>!</code>,
+<code>? :</code>, +not+, +if+, +while+, +unless+, +until+ etc. including the
+modifier forms.
+
+When you use an inclusive range (<code>..</code>), the `off' condition is
+evaluated when the `on' condition changes:
+
+  selected = []
+
+  0.upto 5 do |value|
+    selected << value if value==2..value==2
+  end
+
+  p selected # prints [2]
+
+Here, both sides of the flip-flop are evaluated so the flip-flop turns on and
+off only when +value+ equals 2.  Since the flip-flop turned on in the
+iteration it returns true.
+
+When you use an exclusive range (<code>...</code>), the `off' condition is
+evaluated on the following iteration:
+
+  selected = []
+
+  0.upto 5 do |value|
+    selected << value if value==2...value==2
+  end
+
+  p selected # prints [2, 3, 4, 5]
+
+Here, the flip-flop turns on when +value+ equals 2, but doesn't turn off on the
+same iteration.  The `off' condition isn't evaluated until the following
+iteration and +value+ will never be two again.

+If you are inside a method, you do not need to use +begin+ or +end+ unless you
+wish to limit the scope of rescued exceptions:
+
+  def my_method
+    # ...
+  rescue
+    # ...
+  end
+
+The same is true for a +class+, +module+, and +block+:
+
+  [0, 1, 2].map do |i|
+    10 / i
+  rescue ZeroDivisionError
+    nil
+  end
+  #=> [nil, 10, 5]
+
+You can assign the exception to a local variable by using <tt>=>
+variable_name</tt> at the end of the +rescue+ line:
+
+  begin
+    # ...
+  rescue => exception
+    warn exception.message
+    raise # re-raise the current exception
+  end
+
+By default, StandardError and its subclasses are rescued.  You can rescue a
+specific set of exception classes (and their subclasses) by listing them after
++rescue+:
+
+  begin
+    # ...
+  rescue ArgumentError, NameError
+    # handle ArgumentError or NameError
+  end
+
+You may rescue different types of exceptions in different ways:
+
+  begin
+    # ...
+  rescue ArgumentError
+    # handle ArgumentError
+  rescue NameError
+    # handle NameError
+  rescue
+    # handle any StandardError
+  end
+
+The exception is matched to the rescue section starting at the top, and matches
+only once.  If an ArgumentError is raised in the begin section, it will not be
+handled in the StandardError section.
+
+You may retry rescued exceptions:
+
+  begin
+    # ...
+  rescue
+    # do something that may change the result of the begin block
+    retry
+  end
+
+Execution will resume at the start of the begin block, so be careful not to
+create an infinite loop.
+
+Inside a rescue block is the only valid location for +retry+, all other uses
+will raise a SyntaxError.  If you wish to retry a block iteration use +redo+.
+See {Control Expressions}[rdoc-ref:syntax/control_expressions.rdoc] for
+details.
+
+To always run some code whether an exception was raised or not, use +ensure+:
+
+  begin
+    # ...
+  rescue
+    # ...
+  ensure
+    # this always runs
+  end
+
+You may also run some code when an exception is not raised:
+
+  begin
+    # ...
+  rescue
+    # ...
+  else
+    # this runs only when no exception was raised
+  ensure
+    # ...
+  end

+
+== Boolean and Nil Literals
+
++nil+ and +false+ are both false values.  +nil+ is sometimes used to indicate
+"no value" or "unknown" but evaluates to +false+ in conditional expressions.
+
++true+ is a true value.  All objects except +nil+ and +false+ evaluate to a
+true value in conditional expressions.
+
+== Number Literals
+
+=== \Integer Literals
+
+You can write integers of any size as follows:
+
+  1234
+  1_234
+
+These numbers have the same value, 1,234.  The underscore may be used to
+enhance readability for humans.  You may place an underscore anywhere in the
+number.
+
+You can use a special prefix to write numbers in decimal, hexadecimal, octal
+or binary formats.  For decimal numbers use a prefix of <tt>0d</tt>, for
+hexadecimal numbers use a prefix of <tt>0x</tt>, for octal numbers use a
+prefix of <tt>0</tt> or <tt>0o</tt>, for binary numbers use a prefix of
+<tt>0b</tt>.  The alphabetic component of the number is not case-sensitive.
+
+Examples:
+
+  0d170
+  0D170
+
+  0xaa
+  0xAa
+  0xAA
+  0Xaa
+  0XAa
+  0XaA
+
+  0252
+  0o252
+  0O252
+
+  0b10101010
+  0B10101010
+
+All these numbers have the same decimal value, 170.  Like integers and floats
+you may use an underscore for readability.
+
+=== \Float Literals
+
+Floating-point numbers may be written as follows:
+
+  12.34
+  1234e-2
+  1.234E1
+
+These numbers have the same value, 12.34.  You may use underscores in floating
+point numbers as well.
+
+=== \Rational Literals
+
+You can write a Rational literal using a special suffix, <tt>'r'</tt>.
+
+Examples:
+
+  1r       # => (1/1)
+  2/3r     # => (2/3)   # With denominator.
+  -1r      # => (-1/1)  # With signs.
+  -2/3r    # => (-2/3)
+  2/-3r    # => (-2/3)
+  -2/-3r   # => (2/3)
+  +1/+3r   # => (1/3)
+  1.2r     # => (6/5)   # With fractional part.
+  1_1/2_1r # => (11/21) # With embedded underscores.
+  2/4r     # => (1/2)   # Automatically reduced.
+
+Syntax:
+
+  <rational-literal> = <numerator> [ '/' <denominator> ] 'r'
+  <numerator> = [ <sign> ] <digits> [ <fractional-part> ]
+  <fractional-part> = '.' <digits>
+  <denominator> = [ sign ] <digits>
+  <sign> = '-' | '+'
+  <digits> = <digit> { <digit> | '_' <digit> }
+  <digit> = '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
+
+Note this, which is parsed as \Float numerator <tt>1.2</tt>
+divided by \Rational denominator <tt>3r</tt>,
+resulting in a \Float:
+
+  1.2/3r  # => 0.39999999999999997
+
+=== \Complex Literals
+
+You can write a Complex number as follows (suffixed +i+):
+
+  1i          #=> (0+1i)
+  1i * 1i     #=> (-1+0i)
+
+Also \Rational numbers may be imaginary numbers.
+
+  12.3ri      #=> (0+(123/10)*i)
+
++i+ must be placed after +r+; the opposite is not allowed.
+
+  12.3ir      #=> Syntax error
+
+== Strings
+
+=== \String Literals
+
+The most common way of writing strings is using <tt>"</tt>:
+
+  "This is a string."
+
+The string may be many lines long.
+
+Any internal <tt>"</tt> must be escaped:
+
+  "This string has a quote: \".  As you can see, it is escaped"
+
+Double-quote strings allow escaped characters such as <tt>\n</tt> for
+newline, <tt>\t</tt> for tab, etc.  The full list of supported escape
+sequences are as follows:
+
+  \a             bell, ASCII 07h (BEL)
+  \b             backspace, ASCII 08h (BS)
+  \t             horizontal tab, ASCII 09h (TAB)
+  \n             newline (line feed), ASCII 0Ah (LF)
+  \v             vertical tab, ASCII 0Bh (VT)
+  \f             form feed, ASCII 0Ch (FF)
+  \r             carriage return, ASCII 0Dh (CR)
+  \e             escape, ASCII 1Bh (ESC)
+  \s             space, ASCII 20h (SPC)
+  \\             backslash, \
+  \nnn           octal bit pattern, where nnn is 1-3 octal digits ([0-7])
+  \xnn           hexadecimal bit pattern, where nn is 1-2 hexadecimal digits ([0-9a-fA-F])
+  \unnnn         Unicode character, where nnnn is exactly 4 hexadecimal digits ([0-9a-fA-F])
+  \u{nnnn ...}   Unicode character(s), where each nnnn is 1-6 hexadecimal digits ([0-9a-fA-F])
+  \cx or \C-x    control character, where x is an ASCII printable character
+  \M-x           meta character, where x is an ASCII printable character
+  \M-\C-x        meta control character, where x is an ASCII printable character
+  \M-\cx         same as above
+  \c\M-x         same as above
+  \c? or \C-?    delete, ASCII 7Fh (DEL)
+
+Any other character following a backslash is interpreted as the
+character itself.
+
+Double-quote strings allow interpolation of other values using
+<tt>#{...}</tt>:
+
+  "One plus one is two: #{1 + 1}"
+
+Any expression may be placed inside the interpolated section, but it's best to
+keep the expression small for readability.
+
+You can also use <tt>#@foo</tt>, <tt>#@@foo</tt> and <tt>#$foo</tt> as a
+shorthand for, respectively, <tt>#{ @foo }</tt>, <tt>#{ @@foo }</tt> and
+<tt>#{ $foo }</tt>.
+
+Interpolation may be disabled by escaping the "#" character or using
+single-quote strings:
+
+  '#{1 + 1}' #=> "\#{1 + 1}"
+
+In addition to disabling interpolation, single-quoted strings also disable all
+escape sequences except for the single-quote (<tt>\'</tt>) and backslash
+(<tt>\\\\</tt>).
+
+Adjacent string literals are automatically concatenated by the interpreter:
+
+  "con" "cat" "en" "at" "ion" #=> "concatenation"
+  "This string contains "\
+  "no newlines."              #=> "This string contains no newlines."
+
+Any combination of adjacent single-quote, double-quote, percent strings will
+be concatenated as long as a percent-string is not last.
+
+  %q{a} 'b' "c" #=> "abc"
+  "a" 'b' %q{c} #=> NameError: uninitialized constant q
+
+There is also a character literal notation to represent single
+character strings, which syntax is a question mark (<tt>?</tt>)
+followed by a single character or escape sequence that corresponds to
+a single codepoint in the script encoding:
+
+  ?a       #=> "a"
+  ?abc     #=> SyntaxError
+  ?\n      #=> "\n"
+  ?\s      #=> " "
+  ?\\      #=> "\\"
+  ?\u{41}  #=> "A"
+  ?\C-a    #=> "\x01"
+  ?\M-a    #=> "\xE1"
+  ?\M-\C-a #=> "\x81"
+  ?\C-\M-a #=> "\x81", same as above
+  ?あ      #=> "あ"
+
+See also:

+* {%q: Non-Interpolable String Literals}[#label-25q-3A+Non-Interpolable+String+Literals]
+* {% and %Q: Interpolable String Literals}[#label-25+and+-25Q-3A+Interpolable+String+Literals]
+
+=== Here Document Literals
+
+If you are writing a large block of text you may use a "here document" or
+"heredoc":
+
+  expected_result = <<HEREDOC
+  This would contain specially formatted text.
+
+  That might span many lines
+  HEREDOC
+
+The heredoc starts on the line following <tt><<HEREDOC</tt> and ends with the
+next line that starts with <tt>HEREDOC</tt>.  The result includes the ending
+newline.
+
+You may use any identifier with a heredoc, but all-uppercase identifiers are
+typically used.
+
+You may indent the ending identifier if you place a "-" after <tt><<</tt>:
+
+    expected_result = <<-INDENTED_HEREDOC
+  This would contain specially formatted text.
+
+  That might span many lines
+    INDENTED_HEREDOC
+
+Note that while the closing identifier may be indented, the content is
+always treated as if it is flush left.  If you indent the content those spaces
+will appear in the output.
+
+To have indented content as well as an indented closing identifier, you can use
+a "squiggly" heredoc, which uses a "~" instead of a "-" after <tt><<</tt>:
+
+    expected_result = <<~SQUIGGLY_HEREDOC
+      This would contain specially formatted text.
+
+      That might span many lines
+    SQUIGGLY_HEREDOC
+
+The indentation of the least-indented line will be removed from each line of
+the content.  Note that empty lines and lines consisting solely of literal tabs
+and spaces will be ignored for the purposes of determining indentation, but
+escaped tabs and spaces are considered non-indentation characters.
+
+For the purpose of measuring an indentation, a horizontal tab is regarded as a
+sequence of one to eight spaces such that the column position corresponding to
+its end is a multiple of eight.  The amount to be removed is counted in terms
+of the number of spaces.  If the boundary appears in the middle of a tab, that
+tab is not removed.
+
+A heredoc allows interpolation and escaped characters.  You may disable
+interpolation and escaping by surrounding the opening identifier with single
+quotes:
+
+  expected_result = <<-'EXPECTED'
+  One plus one is #{1 + 1}
+  EXPECTED
+
+  p expected_result # prints: "One plus one is \#{1 + 1}\n"
+
+The identifier may also be surrounded with double quotes (which is the same as
+no quotes) or with backticks.  When surrounded by backticks the HEREDOC
+behaves like Kernel#`:
+
+  puts <<-`HEREDOC`
+  cat #{__FILE__}
+  HEREDOC
+
+When surrounding with quotes, any character but that quote and newline
+(CR and/or LF) can be used as the identifier.
+
+To call a method on a heredoc place it after the opening identifier:
+
+  expected_result = <<-EXPECTED.chomp
+  One plus one is #{1 + 1}
+  EXPECTED
+
+You may open multiple heredocs on the same line, but this can be difficult to
+read:
+
+  puts(<<-ONE, <<-TWO)
+  content for heredoc one
+  ONE
+  content for heredoc two
+  TWO
+
+== \Symbol Literals
+
+A Symbol represents a name inside the ruby interpreter.  See Symbol for more
+details on what symbols are and when ruby creates them internally.
+
+You may reference a symbol using a colon: <tt>:my_symbol</tt>.
+
+You may also create symbols by interpolation:
+
+  :"my_symbol1"
+  :"my_symbol#{1 + 1}"
+
+Like strings, a single-quote may be used to disable interpolation:
+
+  :'my_symbol#{1 + 1}' #=> :"my_symbol\#{1 + 1}"
+
+When creating a Hash, there is a special syntax for referencing a Symbol as
+well.
+
+See also:
+
+* {%s: Symbol Literals}[#label-25s-3A+Symbol+Literals]
+
+
+== \Array Literals
+
+An array is created using the objects between <tt>[</tt> and <tt>]</tt>:
+
+  [1, 2, 3]
+
+You may place expressions inside the array:
+
+  [1, 1 + 1, 1 + 2]
+  [1, [1 + 1, [1 + 2]]]
+
+See also:
+
+* {%w and %W: String-Array Literals}[#label-25w+and+-25W-3A+String-Array+Literals]
+* {%i and %I: Symbol-Array Literals}[#label-25i+and+-25I-3A+Symbol-Array+Literals]
+
+See Array for the methods you may use with an array.
+
+== \Hash Literals
+
+A hash is created using key-value pairs between <tt>{</tt> and <tt>}</tt>:
+
+  { "a" => 1, "b" => 2 }
+
+Both the key and value may be any object.
+
+You can create a hash using symbol keys with the following syntax:
+
+  { a: 1, b: 2 }
+
+This same syntax is used for keyword arguments for a method.
+
+Like Symbol literals, you can quote symbol keys.
+
+  { "a 1": 1, "b #{1 + 1}": 2 }
+
+is equal to
+
+  { :"a 1" => 1, :"b 2" => 2 }
+
+Hash values can be omitted, meaning that value will be fetched from the context
+by the name of the key:
+
+  x = 100
+  y = 200
+  h = { x:, y: }
+  #=> {:x=>100, :y=>200}
+
+See Hash for the methods you may use with a hash.
+
+== \Range Literals
+
+A range represents an interval of values.  The range may include or exclude
+its ending value.
+
+  (1..2)  # includes its ending value
+  (1...2) # excludes its ending value
+  (1..)   # endless range, representing infinite sequence from 1 to Infinity
+  (..1)   # beginless range, representing infinite sequence from -Infinity to 1
+
+You may create a range of any object.  See the Range documentation for details
+on the methods you need to implement.
+
+== \Regexp Literals
+
+A regular expression may be created using leading and trailing
+slash (<tt>'/'</tt>) characters:
+
+  re = /foo/ # => /foo/
+  re.class   # => Regexp
+
+The trailing slash may be followed by one or more _flag_ characters
+that modify the behavior.
+See {Regexp options}[rdoc-ref:Regexp@Options] for details.
+
+Interpolation may be used inside regular expressions along with escaped
+characters.  Note that a regular expression may require additional escaped
+characters than a string.
+
+See also:
+
+* {%r: Regexp Literals}[#label-25r-3A+Regexp+Literals]
+
+See Regexp for a description of the syntax of regular expressions.
+
+== Lambda Proc Literals
+
+A lambda proc can be created with <tt>-></tt>:
+
+  -> { 1 + 1 }
+
+Calling the above proc will give a result of <tt>2</tt>.
+
+You can require arguments for the proc as follows:
+
+  ->(v) { 1 + v }
+
+This proc will add one to its argument.
+
+== Percent Literals
+
+Each of the literals in described in this section
+may use these paired delimiters:
+
+* <tt>[</tt> and <tt>]</tt>.
+* <tt>(</tt> and <tt>)</tt>.
+* <tt>{</tt> and <tt>}</tt>.
+* <tt><</tt> and <tt>></tt>.
+* Any other character, as both beginning and ending delimiters.
+
+These are demonstrated in the next section.
+
+=== <tt>%q</tt>: Non-Interpolable String Literals
+
+You can write a non-interpolable string with <tt>%q</tt>.
+The created string is the same as if you created it with single quotes:
+
+  %[foo bar baz]        # => "foo bar baz" # Using [].
+  %(foo bar baz)        # => "foo bar baz" # Using ().
+  %{foo bar baz}        # => "foo bar baz" # Using {}.
+  %<foo bar baz>        # => "foo bar baz" # Using <>.
+  %|foo bar baz|        # => "foo bar baz" # Using two |.
+  %:foo bar baz:        # => "foo bar baz" # Using two :.
+  %q(1 + 1 is #{1 + 1}) # => "1 + 1 is \#{1 + 1}" # No interpolation.
+
+=== <tt>% and %Q</tt>: Interpolable String Literals
+
+You can write an interpolable string with <tt>%Q</tt>
+or with its alias <tt>%</tt>:
+
+  %[foo bar baz]       # => "foo bar baz"
+  %(1 + 1 is #{1 + 1}) # => "1 + 1 is 2" # Interpolation.
+
+=== <tt>%w and %W</tt>: String-Array Literals
+
+You can write an array of strings with <tt>%w</tt> (non-interpolable)
+or <tt>%W</tt> (interpolable):
+
+  %w[foo bar baz]       # => ["foo", "bar", "baz"]
+  %w[1 % *]             # => ["1", "%", "*"]
+  # Use backslash to embed spaces in the strings.
+  %w[foo\ bar baz\ bat] # => ["foo bar", "baz bat"]
+  %w(#{1 + 1})          # => ["\#{1", "+", "1}"]
+  %W(#{1 + 1})          # => ["2"]
+
+=== <tt>%i and %I</tt>: Symbol-Array Literals
+
+You can write an array of symbols with <tt>%i</tt> (non-interpolable)
+or <tt>%I</tt> (interpolable):
+
+  %i[foo bar baz]       # => [:foo, :bar, :baz]
+  %i[1 % *]             # => [:"1", :%, :*]
+  # Use backslash to embed spaces in the symbols.
+  %i[foo\ bar baz\ bat] # => [:"foo bar", :"baz bat"]
+  %i(#{1 + 1})          # => [:"\#{1", :+, :"1}"]
+  %I(#{1 + 1})          # => [:"2"]
+
+=== <tt>%s</tt>: Symbol Literals
+
+You can write a symbol with <tt>%s</tt>:
+
+  %s[foo]     # => :foo
+  %s[foo bar] # => :"foo bar"
+
+=== <tt>%r</tt>: Regexp Literals
+
+You can write a regular expression with <tt>%r</tt>;
+the character used as the leading and trailing delimiter
+may be (almost) any character:
+
+  %r/foo/             # => /foo/
+  %r:name/value pair: # => /name\/value pair/
+
+A few "symmetrical" character pairs may be used as delimiters:
+
+  %r[foo] # => /foo/
+  %r{foo} # => /foo/
+  %r(foo) # => /foo/
+  %r<foo> # => /foo/
+
+The trailing delimiter may be followed by one or more _flag_ characters
+that modify the behavior.
+See {Regexp options}[rdoc-ref:Regexp@Options] for details.
+
+=== <tt>%x</tt>: Backtick Literals
+
+You can write and execute a shell command with <tt>%x</tt>:
+
+  %x(echo 1) # => "1\n"

+= Methods
+
+Methods implement the functionality of your program.  Here is a simple method
+definition:
+
+  def one_plus_one
+    1 + 1
+  end
+
+A method definition consists of the +def+ keyword, a method name, the body of
+the method, +return+ value and the +end+ keyword.  When called the method will
+execute the body of the method.  This method returns +2+.
+
+Since Ruby 3.0, there is also a shorthand syntax for methods consisting
+of exactly one expression:
+
+   def one_plus_one = 1 + 1
+
+This section only covers defining methods.  See also the {syntax documentation
+on calling methods}[rdoc-ref:syntax/calling_methods.rdoc].
+
+== Method Names
+
+Method names may be one of the operators or must start a letter or a character
+with the eighth bit set. It may contain letters, numbers, an <code>_</code>
+(underscore or low line) or a character with the eighth bit set. The convention
+is to use underscores to separate words in a multiword method name:
+
+  def method_name
+    puts "use underscores to separate words"
+  end
+
+Ruby programs must be written in a US-ASCII-compatible character set such as
+UTF-8, ISO-8859-1 etc. In such character sets if the eighth bit is set it
+indicates an extended character. Ruby allows method names and other identifiers
+to contain such characters. Ruby programs cannot contain some characters like
+ASCII NUL (<code>\x00</code>).
+
+The following are examples of valid Ruby methods:
+
+  def hello
+    "hello"
+  end
+
+  def こんにちは
+    puts "means hello in Japanese"
+  end
+
+Typically method names are US-ASCII compatible since the keys to type them
+exist on all keyboards.
+
+Method names may end with a <code>!</code> (bang or exclamation mark), a
+<code>?</code> (question mark), or <code>=</code> (equals sign).
+
+The bang methods (<code>!</code> at the end of the method name) are called and
+executed just like any other method. However, by convention, a method with an
+exclamation point or bang is considered dangerous. In Ruby's core library the
+dangerous method implies that when a method ends with a bang (<code>!</code>),
+it indicates that unlike its non-bang equivalent, permanently modifies its
+receiver. Almost always, the Ruby core library will have a non-bang
+counterpart (method name which does NOT end with <code>!</code>) of every bang
+method (method name which does end with <code>!</code>) that does not modify
+the receiver. This convention is typically true for the Ruby core library but
+may or may not hold true for other Ruby libraries.
+
+Methods that end with a question mark by convention return boolean, but they
+may not always return just +true+ or +false+.  Often, they will return an
+object to indicate a true value (or "truthy" value).
+
+Methods that end with an equals sign indicate an assignment method.
+
+  class C
+    def attr
+      @attr
+    end
+
+    def attr=(val)
+      @attr = val
+    end
+  end
+
+  c = C.new
+  c.attr      #=> nil
+  c.attr = 10 # calls "attr=(10)"
+  c.attr      #=> 10
+
+Assignment methods can not be defined using the shorthand syntax.
+
+These are method names for the various Ruby operators.  Each of these
+operators accepts only one argument.  Following the operator is the typical
+use or name of the operator.  Creating an alternate meaning for the operator
+may lead to confusion as the user expects plus to add things, minus to
+subtract things, etc.  Additionally, you cannot alter the precedence of the
+operators.
+
+<code>+</code>   :: add
+<code>-</code>   :: subtract
+<code>*</code>   :: multiply
+<code>**</code>  :: power
+<code>/</code>   :: divide
+<code>%</code>   :: modulus division, String#%
+<code>&</code>   :: AND
+<code>^</code>   :: XOR (exclusive OR)
+<code>>></code>  :: right-shift
+<code><<</code>  :: left-shift, append
+<code>==</code>  :: equal
+<code>!=</code>  :: not equal
+<code>===</code> :: case equality.  See Object#===
+<code>=~</code>  :: pattern match.  (Not just for regular expressions)
+<code>!~</code>  :: does not match
+<code><=></code> :: comparison aka spaceship operator.  See Comparable
+<code><</code>   :: less-than
+<code><=</code>  :: less-than or equal
+<code>></code>   :: greater-than
+<code>>=</code>  :: greater-than or equal
+
+To define unary methods minus and plus, follow the operator with an
+<code>@</code> as in <code>+@</code>:
+
+  class C
+    def -@
+      puts "you inverted this object"
+    end
+  end
+
+  obj = C.new
+
+  -obj # prints "you inverted this object"
+
+The <code>@</code> is needed to differentiate unary minus and plus
+operators from binary minus and plus operators.
+
+You can also follow tilde and not (<code>!</code>) unary methods with
+<code>@</code>, but it is not required as there are no binary tilde
+and not operators.
+
+Unary methods accept zero arguments.
+
+Additionally, methods for element reference and assignment may be defined:
+<code>[]</code> and <code>[]=</code> respectively. Both can take one or more
+arguments, and element reference can take none.
+
+  class C
+    def [](a, b)
+      puts a + b
+    end
+
+    def []=(a, b, c)
+      puts a * b + c
+    end
+  end
+
+  obj = C.new
+
+  obj[2, 3]     # prints "5"
+  obj[2, 3] = 4 # prints "10"
+
+== Return Values
+
+By default, a method returns the last expression that was evaluated in the body
+of the method.  In the example above, the last (and only) expression evaluated
+was the simple sum <code>1 + 1</code>.  The +return+ keyword can be used to
+make it explicit that a method returns a value.
+
+  def one_plus_one
+    return 1 + 1
+  end
+
+It can also be used to make a method return before the last expression is
+evaluated.
+
+  def two_plus_two
+    return 2 + 2
+    1 + 1  # this expression is never evaluated
+  end
+
+Note that for assignment methods the return value will be ignored when using
+the assignment syntax.  Instead, the argument will be returned:
+
+  def a=(value)
+    return 1 + value
+  end
+
+  p(self.a = 5) # prints 5
+
+The actual return value will be returned when invoking the method directly:
+
+  p send(:a=, 5) # prints 6
+
+== Scope
+
+The standard syntax to define a method:
+
+  def my_method
+    # ...
+  end
+
+adds the method to a class.  You can define an instance method on a specific
+class with the +class+ keyword:
+
+  class C
+    def my_method
+      # ...
+    end
+  end
+
+A method may be defined on another object.  You may define a "class method" (a
+method that is defined on the class, not an instance of the class) like this:
+
+  class C
+    def self.my_method
+      # ...
+    end
+  end
+
+However, this is simply a special case of a greater syntactical power in Ruby,
+the ability to add methods to any object.  Classes are objects, so adding
+class methods is simply adding methods to the Class object.
+
+The syntax for adding a method to an object is as follows:
+
+  greeting = "Hello"
+
+  def greeting.broaden
+    self + ", world!"
+  end
+
+  greeting.broaden # returns "Hello, world!"
+
++self+ is a keyword referring to the current object under consideration
+by the compiler, which might make the use of +self+ in defining a class
+method above a little clearer.  Indeed, the example of adding a +hello+
+method to the class +String+ can be rewritten thus:
+
+  def String.hello
+    "Hello, world!"
+  end
+
+A method defined like this is called a "singleton method".  +broaden+ will only
+exist on the string instance +greeting+.  Other strings will not have +broaden+.
+
+== Overriding
+
+When Ruby encounters the +def+ keyword, it doesn't consider it an error if the
+method already exists: it simply redefines it.  This is called
+_overriding_.  Rather like extending core classes, this is a potentially
+dangerous ability, and should be used sparingly because it can cause unexpected
+results.  For example, consider this irb session:
+
+  >> "43".to_i
+  => 43
+  >> class String
+  >>   def to_i
+  >>     42
+  >>   end
+  >> end
+  => nil
+  >> "43".to_i
+  => 42
+
+This will effectively sabotage any code which makes use of the method
+<code>String#to_i</code> to parse numbers from strings.
+
+== Arguments
+
+A method may accept arguments.  The argument list follows the method name:
+
+  def add_one(value)
+    value + 1
+  end
+
+When called, the user of the +add_one+ method must provide an argument.  The
+argument is a local variable in the method body.  The method will then add one
+to this argument and return the value.  If given +1+ this method will
+return +2+.
+
+The parentheses around the arguments are optional:
+
+  def add_one value
+    value + 1
+  end
+
+The parentheses are mandatory in shorthand method definitions:
+
+  # OK
+  def add_one(value) = value + 1
+  # SyntaxError
+  def add_one value = value + 1
+
+Multiple arguments are separated by a comma:
+
+  def add_values(a, b)
+    a + b
+  end
+
+When called, the arguments must be provided in the exact order.  In other
+words, the arguments are positional.
+
+=== Default Values
+
+Arguments may have default values:
+
+  def add_values(a, b = 1)
+    a + b
+  end
+
+The default value does not need to appear first, but arguments with defaults
+must be grouped together.  This is ok:
+
+  def add_values(a = 1, b = 2, c)
+    a + b + c
+  end
+
+This will raise a SyntaxError:
+
+  def add_values(a = 1, b, c = 1)
+    a + b + c
+  end
+
+Default argument values can refer to arguments that have already been
+evaluated as local variables, and argument values are always evaluated
+left to right. So this is allowed:
+
+  def add_values(a = 1, b = a)
+    a + b
+  end
+  add_values
+  # => 2
+
+But this will raise a +NameError+ (unless there is a method named
++b+ defined):
+
+  def add_values(a = b, b = 1)
+    a + b
+  end
+  add_values
+  # NameError (undefined local variable or method `b' for main:Object)
+
+=== Array Decomposition
+
+You can decompose (unpack or extract values from) an Array using extra
+parentheses in the arguments:
+
+  def my_method((a, b))
+    p a: a, b: b
+  end
+
+  my_method([1, 2])
+
+This prints:
+
+  {:a=>1, :b=>2}
+
+If the argument has extra elements in the Array they will be ignored:
+
+  def my_method((a, b))
+    p a: a, b: b
+  end
+
+  my_method([1, 2, 3])
+
+This has the same output as above.
+
+You can use a <code>*</code> to collect the remaining arguments.  This splits
+an Array into a first element and the rest:
+
+  def my_method((a, *b))
+    p a: a, b: b
+  end
+
+  my_method([1, 2, 3])
+
+This prints:
+
+  {:a=>1, :b=>[2, 3]}
+
+The argument will be decomposed if it responds to #to_ary.  You should only
+define #to_ary if you can use your object in place of an Array.
+
+Use of the inner parentheses only uses one of the sent arguments.  If the
+argument is not an Array it will be assigned to the first argument in the
+decomposition and the remaining arguments in the decomposition will be +nil+:
+
+  def my_method(a, (b, c), d)
+    p a: a, b: b, c: c, d: d
+  end
+
+  my_method(1, 2, 3)
+
+This prints:
+
+  {:a=>1, :b=>2, :c=>nil, :d=>3}
+
+You can nest decomposition arbitrarily:
+
+  def my_method(((a, b), c))
+    # ...
+  end
+
+=== Array/Hash Argument
+
+Prefixing an argument with <code>*</code> causes any remaining arguments to be
+converted to an Array:
+
+  def gather_arguments(*arguments)
+    p arguments
+  end
+
+  gather_arguments 1, 2, 3 # prints [1, 2, 3]
+
+The array argument must appear before any keyword arguments.
+
+It is possible to gather arguments at the beginning or in the middle:
+
+  def gather_arguments(first_arg, *middle_arguments, last_arg)
+    p middle_arguments
+  end
+
+  gather_arguments 1, 2, 3, 4 # prints [2, 3]
+
+The array argument will capture a Hash as the last entry if keywords were
+provided by the caller after all positional arguments.
+
+  def gather_arguments(*arguments)
+    p arguments
+  end
+
+  gather_arguments 1, a: 2 # prints [1, {:a=>2}]
+
+However, this only occurs if the method does not declare any keyword arguments.
+
+  def gather_arguments_keyword(*positional, keyword: nil)
+   p positional: positional, keyword: keyword
+  end
+
+  gather_arguments_keyword 1, 2, three: 3
+  #=> raises: unknown keyword: three (ArgumentError)
+
+Also, note that a bare <code>*</code> can be used to ignore arguments:
+
+  def ignore_arguments(*)
+  end
+
+You can also use a bare <code>*</code> when calling a method to pass the
+arguments directly to another method:
+
+  def delegate_arguments(*)
+    other_method(*)
+  end
+
+=== Keyword Arguments
+
+Keyword arguments are similar to positional arguments with default values:
+
+  def add_values(first: 1, second: 2)
+    first + second
+  end
+
+Arbitrary keyword arguments will be accepted with <code>**</code>:
+
+  def gather_arguments(first: nil, **rest)
+    p first, rest
+  end
+
+  gather_arguments first: 1, second: 2, third: 3
+  # prints 1 then {:second=>2, :third=>3}
+
+When calling a method with keyword arguments the arguments may appear in any
+order.  If an unknown keyword argument is sent by the caller, and the method
+does not accept arbitrary keyword arguments, an ArgumentError is raised.
+
+To require a specific keyword argument, do not include a default value
+for the keyword argument:
+
+  def add_values(first:, second:)
+    first + second
+  end
+  add_values
+  # ArgumentError (missing keywords: first, second)
+  add_values(first: 1, second: 2)
+  # => 3
+
+When mixing keyword arguments and positional arguments, all positional
+arguments must appear before any keyword arguments.
+
+Also, note that <code>**</code> can be used to ignore keyword arguments:
+
+  def ignore_keywords(**)
+  end
+
+You can also use <code>**</code> when calling a method to delegate
+keyword arguments to another method:
+
+  def delegate_keywords(**)
+    other_method(**)
+  end
+
+To mark a method as accepting keywords, but not actually accepting
+keywords, you can use the <code>**nil</code>:
+
+  def no_keywords(**nil)
+  end
+
+Calling such a method with keywords or a non-empty keyword splat will
+result in an ArgumentError. This syntax is supported so that keywords
+can be added to the method later without affected backwards compatibility.
+
+If a method definition does not accept any keywords, and the
+<code>**nil</code> syntax is not used, any keywords provided when calling
+the method will be converted to a Hash positional argument:
+
+  def meth(arg)
+    arg
+  end
+  meth(a: 1)
+  # => {:a=>1}
+
+=== Block Argument
+
+The block argument is indicated by <code>&</code> and must come last:
+
+  def my_method(&my_block)
+    my_block.call(self)
+  end
+
+Most frequently the block argument is used to pass a block to another method:
+
+  def each_item(&block)
+    @items.each(&block)
+  end
+
+You are not required to give a name to the block if you will just be passing
+it to another method:
+
+  def each_item(&)
+    @items.each(&)
+  end
+
+If you are only going to call the block and will not otherwise manipulate it
+or send it to another method, using <code>yield</code> without an explicit
+block parameter is preferred.  This method is equivalent to the first method
+in this section:
+
+  def my_method
+    yield self
+  end
+
+=== Argument Forwarding
+
+Since Ruby 2.7, an all-arguments forwarding syntax is available:
+
+  def concrete_method(*positional_args, **keyword_args, &block)
+    [positional_args, keyword_args, block]
+  end
+
+  def forwarding_method(...)
+    concrete_method(...)
+  end
+
+  forwarding_method(1, b: 2) { puts 3 }
+  #=>  [[1], {:b=>2}, #<Proc:...skip...>]
+
+Calling with forwarding <code>...</code> is available only in methods
+defined with <code>...</code>.
+
+  def regular_method(arg, **kwarg)
+    concrete_method(...) # Syntax error
+  end
+
+Since Ruby 3.0, there can be leading arguments before <code>...</code>
+both in definitions and in invocations (but in definitions they can be
+only positional arguments without default values).
+
+  def request(method, path, **headers)
+    puts "#{method.upcase} #{path} #{headers}"
+  end
+
+  def get(...)
+    request(:GET, ...) # leading argument in invoking
+  end
+
+  get('http://ruby-lang.org', 'Accept' => 'text/html')
+  # Prints: GET http://ruby-lang.org {"Accept"=>"text/html"}
+
+  def logged_get(msg, ...) # leading argument in definition
+    puts "Invoking #get: #{msg}"
+    get(...)
+  end
+
+  logged_get('Ruby site', 'http://ruby-lang.org')
+  # Prints:
+  #   Invoking #get: Ruby site
+  #   GET http://ruby-lang.org {}
+
+Note that omitting parentheses in forwarding calls may lead to
+unexpected results:
+
+  def log(...)
+    puts ...  # This would be treated as `puts()...',
+              # i.e. endless range from puts result
+  end
+
+  log("test")
+  # Prints: warning: ... at EOL, should be parenthesized?
+  # ...and then empty line
+
+== Exception Handling
+
+Methods have an implied exception handling block so you do not need to use
++begin+ or +end+ to handle exceptions.  This:
+
+  def my_method
+    begin
+      # code that may raise an exception
+    rescue
+      # handle exception
+    end
+  end
+
+May be written as:
+
+  def my_method
+    # code that may raise an exception
+  rescue
+    # handle exception
+  end
+
+Similarly, if you wish to always run code even if an exception is raised,
+you can use +ensure+ without +begin+ and +end+:
+
+  def my_method
+    # code that may raise an exception
+  ensure
+    # code that runs even if previous code raised an exception
+  end
+
+You can also combine +rescue+ with +ensure+ and/or +else+, without
++begin+ and +end+:
+
+  def my_method
+    # code that may raise an exception
+  rescue
+    # handle exception
+  else
+    # only run if no exception raised above
+  ensure
+    # code that runs even if previous code raised an exception
+  end
+
+If you wish to rescue an exception for only part of your method, use +begin+ and
++end+.  For more details see the page on {exception
+handling}[rdoc-ref:syntax/exceptions.rdoc].

+= Miscellaneous Syntax
+
+== Ending an Expression
+
+Ruby uses a newline as the end of an expression.  When ending a line with an
+operator, open parentheses, comma, etc. the expression will continue.
+
+You can end an expression with a <code>;</code> (semicolon).  Semicolons are
+most frequently used with <code>ruby -e</code>.
+
+== Indentation
+
+Ruby does not require any indentation.  Typically, ruby programs are indented
+two spaces.
+
+If you run ruby with warnings enabled and have an indentation mismatch, you
+will receive a warning.
+
+== +alias+
+
+The +alias+ keyword is most frequently used to alias methods.  When aliasing a
+method, you can use either its name or a symbol:
+
+  alias new_name old_name
+  alias :new_name :old_name
+
+For methods, Module#alias_method can often be used instead of +alias+.
+
+You can also use +alias+ to alias global variables:
+
+  $old = 0
+
+  alias $new $old
+
+  p $new # prints 0
+
+You may use +alias+ in any scope.
+
+== +undef+
+
+The +undef+ keyword prevents the current class from responding to calls to the
+named methods.
+
+  undef my_method
+
+You may use symbols instead of method names:
+
+  undef :my_method
+
+You may undef multiple methods:
+
+  undef method1, method2
+
+You may use +undef+ in any scope.  See also Module#undef_method
+
+== +defined?+
+
++defined?+ is a keyword that returns a string describing its argument:
+
+  p defined?(UNDEFINED_CONSTANT) # prints nil
+  p defined?(RUBY_VERSION)       # prints "constant"
+  p defined?(1 + 1)              # prints "method"
+
+You don't need to use parenthesis with +defined?+, but they are recommended due
+to the {low precedence}[rdoc-ref:syntax/precedence.rdoc] of +defined?+.
+
+For example, if you wish to check if an instance variable exists and that the
+instance variable is zero:
+
+  defined? @instance_variable && @instance_variable.zero?
+
+This returns <code>"expression"</code>, which is not what you want if the
+instance variable is not defined.
+
+  @instance_variable = 1
+  defined?(@instance_variable) && @instance_variable.zero?
+
+Adding parentheses when checking if the instance variable is defined is a
+better check.  This correctly returns +nil+ when the instance variable is not
+defined and +false+ when the instance variable is not zero.
+
+Using the specific reflection methods such as instance_variable_defined? for
+instance variables or const_defined? for constants is less error prone than
+using +defined?+.
+
++defined?+ handles some regexp global variables specially based on whether
+there is an active regexp match and how many capture groups there are:
+
+  /b/ =~ 'a'
+  defined?($~) # => "global-variable"
+  defined?($&) # => nil
+  defined?($`) # => nil
+  defined?($') # => nil
+  defined?($+) # => nil
+  defined?($1) # => nil
+  defined?($2) # => nil
+
+  /./ =~ 'a'
+  defined?($~) # => "global-variable"
+  defined?($&) # => "global-variable"
+  defined?($`) # => "global-variable"
+  defined?($') # => "global-variable"
+  defined?($+) # => nil
+  defined?($1) # => nil
+  defined?($2) # => nil
+
+  /(.)/ =~ 'a'
+  defined?($~) # => "global-variable"
+  defined?($&) # => "global-variable"
+  defined?($`) # => "global-variable"
+  defined?($') # => "global-variable"
+  defined?($+) # => "global-variable"
+  defined?($1) # => "global-variable"
+  defined?($2) # => nil
+
+== +BEGIN+ and +END+
+
++BEGIN+ defines a block that is run before any other code in the current file.
+It is typically used in one-liners with <code>ruby -e</code>.  Similarly +END+
+defines a block that is run after any other code.
+
++BEGIN+ must appear at top-level and +END+ will issue a warning when you use it
+inside a method.
+
+Here is an example:
+
+  BEGIN {
+    count = 0
+  }
+
+You must use <code>{</code> and <code>}</code> you may not use +do+ and +end+.
+
+Here is an example one-liner that adds numbers from standard input or any files
+in the argument list:
+
+  ruby -ne 'BEGIN { count = 0 }; END { puts count }; count += gets.to_i'

+= Modules
+
+Modules serve two purposes in Ruby, namespacing and mix-in functionality.
+
+A namespace can be used to organize code by package or functionality that
+separates common names from interference by other packages.  For example, the
+IRB namespace provides functionality for irb that prevents a collision
+for the common name "Context".
+
+Mix-in functionality allows sharing common methods across multiple classes or
+modules.  Ruby comes with the Enumerable mix-in module which provides many
+enumeration methods based on the +each+ method and Comparable allows comparison
+of objects based on the <code><=></code> comparison method.
+
+Note that there are many similarities between modules and classes.  Besides the
+ability to mix-in a module, the description of modules below also applies to
+classes.
+
+== Module Definition
+
+A module is created using the +module+ keyword:
+
+  module MyModule
+    # ...
+  end
+
+A module may be reopened any number of times to add, change or remove
+functionality:
+
+  module MyModule
+    def my_method
+    end
+  end
+
+  module MyModule
+    alias my_alias my_method
+  end
+
+  module MyModule
+    remove_method :my_method
+  end
+
+Reopening classes is a very powerful feature of Ruby, but it is best to only
+reopen classes you own.  Reopening classes you do not own may lead to naming
+conflicts or difficult to diagnose bugs.
+
+== Nesting
+
+Modules may be nested:
+
+  module Outer
+    module Inner
+    end
+  end
+
+Many packages create a single outermost module (or class) to provide a
+namespace for their functionality.
+
+You may also define inner modules using <code>::</code> provided the outer
+modules (or classes) are already defined:
+
+  module Outer::Inner::GrandChild
+  end
+
+Note that this will raise a +NameError+ if +Outer+ and
+<code>Outer::Inner</code> are not already defined.
+
+This style has the benefit of allowing the author to reduce the amount
+of indentation.  Instead of 3 levels of indentation only one is necessary.
+However, the scope of constant lookup is different for creating a namespace
+using this syntax instead of the more verbose syntax.
+
+== Scope
+
+=== +self+
+
++self+ refers to the object that defines the current scope.  +self+ will change
+when entering a different method or when defining a new module.
+
+=== Constants
+
+Accessible constants are different depending on the module nesting (which
+syntax was used to define the module).  In the following example
+the constant <code>A::Z</code> is accessible from B as A is part of the
+nesting:
+
+  module A
+    Z = 1
+
+    module B
+      p Module.nesting #=> [A::B, A]
+      p Z #=> 1
+    end
+  end
+
+However, if you use <code>::</code> to define <code>A::B</code> without
+nesting it inside +A+, a NameError exception will be raised because the nesting
+does not include +A+:
+
+  module A
+    Z = 1
+  end
+
+  module A::B
+    p Module.nesting #=> [A::B]
+    p Z #=> raises NameError
+  end
+
+If a constant is defined at the top-level you may preceded it with
+<code>::</code> to reference it:
+
+  Z = 0
+
+  module A
+    Z = 1
+
+    module B
+      p ::Z #=> 0
+    end
+  end
+
+=== Methods
+
+For method definition documentation see the {syntax documentation for
+methods}[rdoc-ref:syntax/methods.rdoc].
+
+Class methods may be called directly.  (This is slightly confusing, but a
+method on a module is often called a "class method" instead of a "module
+method".  See also Module#module_function which can convert an instance method
+into a class method.)
+
+When a class method references a constant, it uses the same rules as referencing
+it outside the method as the scope is the same.
+
+Instance methods defined in a module are only callable when included.  These
+methods have access to the constants defined when they were included through
+the ancestors list:
+
+  module A
+    Z = 1
+
+    def z
+      Z
+    end
+  end
+
+  include A
+
+  p self.class.ancestors #=> [Object, A, Kernel, BasicObject]
+  p z #=> 1
+
+=== Visibility
+
+Ruby has three types of visibility.  The default is +public+.  A public method
+may be called from any other object.
+
+The second visibility is +protected+.  When calling a protected method the
+sender must inherit the Class or Module which defines the method.  Otherwise a
+NoMethodError will be raised.
+
+Protected visibility is most frequently used to define <code>==</code> and
+other comparison methods where the author does not wish to expose an object's
+state to any caller and would like to restrict it only to inherited classes.
+
+Here is an example:
+
+  class A
+    def n(other)
+      other.m
+    end
+  end
+
+  class B < A
+    def m
+      1
+    end
+
+    protected :m
+
+  end
+
+  class C < B
+  end
+
+  a = A.new
+  b = B.new
+  c = C.new
+
+  c.n b #=> 1 -- C is a subclass of B
+  b.n b #=> 1 -- m called on defining class
+  a.n b # raises NoMethodError A is not a subclass of B
+
+The third visibility is +private+.  A private method may only be called from
+inside the owner class without a receiver, or with a literal +self+
+as a receiver.  If a private method is called with a
+receiver other than a literal +self+, a NoMethodError will be raised.
+
+  class A
+    def without
+      m
+    end
+
+    def with_self
+      self.m
+    end
+
+    def with_other
+      A.new.m
+    end
+
+    def with_renamed
+      copy = self
+      copy.m
+    end
+
+    def m
+      1
+    end
+
+    private :m
+  end
+
+  a = A.new
+  a.without      #=> 1
+  a.with_self    #=> 1
+  a.with_other   # NoMethodError (private method `m' called for #<A:0x0000559c287f27d0>)
+  a.with_renamed # NoMethodError (private method `m' called for #<A:0x0000559c285f8330>)
+
+=== +alias+ and +undef+
+
+You may also alias or undefine methods, but these operations are not
+restricted to modules or classes.  See the {miscellaneous syntax
+section}[rdoc-ref:syntax/miscellaneous.rdoc] for documentation.
+
+= Classes
+
+Every class is also a module, but unlike modules a class may not be mixed-in to
+another module (or class).  Like a module, a class can be used as a namespace.
+A class also inherits methods and constants from its superclass.
+
+== Defining a class
+
+Use the +class+ keyword to create a class:
+
+  class MyClass
+    # ...
+  end
+
+If you do not supply a superclass your new class will inherit from Object.  You
+may inherit from a different class using <code><</code> followed by a class
+name:
+
+  class MySubclass < MyClass
+    # ...
+  end
+
+There is a special class BasicObject which is designed as a blank class and
+includes a minimum of built-in methods.  You can use BasicObject to create an
+independent inheritance structure.  See the BasicObject documentation for
+further details.
+
+== Inheritance
+
+Any method defined on a class is callable from its subclass:
+
+  class A
+    Z = 1
+
+    def z
+      Z
+    end
+  end
+
+  class B < A
+  end
+
+  p B.new.z #=> 1
+
+The same is true for constants:
+
+  class A
+    Z = 1
+  end
+
+  class B < A
+    def z
+      Z
+    end
+  end
+
+  p B.new.z #=> 1
+
+You can override the functionality of a superclass method by redefining the
+method:
+
+  class A
+    def m
+      1
+    end
+  end
+
+  class B < A
+    def m
+      2
+    end
+  end
+
+  p B.new.m #=> 2
+
+If you wish to invoke the superclass functionality from a method use +super+:
+
+  class A
+    def m
+      1
+    end
+  end
+
+  class B < A
+    def m
+      2 + super
+    end
+  end
+
+  p B.new.m #=> 3
+
+When used without any arguments +super+ uses the arguments given to the
+subclass method.  To send no arguments to the superclass method use
+<code>super()</code>.  To send specific arguments to the superclass method
+provide them manually like <code>super(2)</code>.
+
++super+ may be called as many times as you like in the subclass method.
+
+= Singleton Classes
+
+The singleton class (also known as the metaclass or eigenclass) of an object is
+a class that holds methods for only that instance.  You can access the
+singleton class of an object using <code>class << object</code> like this:
+
+  class C
+  end
+
+  class << C
+    # self is the singleton class here
+  end
+
+Most frequently you'll see the singleton class accessed like this:
+
+  class C
+    class << self
+      # ...
+    end
+  end
+
+This allows definition of methods and attributes on a class (or module) without
+needing to write <code>def self.my_method</code>.
+
+Since you can open the singleton class of any object this means that this code
+block:
+
+  o = Object.new
+
+  def o.my_method
+    1 + 1
+  end
+
+is equivalent to this code block:
+
+  o = Object.new
+
+  class << o
+    def my_method
+      1 + 1
+    end
+  end
+
+Both objects will have a +my_method+ that returns +2+.

+= Pattern matching
+
+Pattern matching is a feature allowing deep matching of structured values: checking the structure and binding the matched parts to local variables.
+
+Pattern matching in Ruby is implemented with the +case+/+in+ expression:
+
+    case <expression>
+    in <pattern1>
+      ...
+    in <pattern2>
+      ...
+    in <pattern3>
+      ...
+    else
+      ...
+    end
+
+(Note that +in+ and +when+ branches can NOT be mixed in one +case+ expression.)
+
+Or with the <code>=></code> operator and the +in+ operator, which can be used in a standalone expression:
+
+    <expression> => <pattern>
+
+    <expression> in <pattern>
+
+The +case+/+in+ expression is _exhaustive_: if the value of the expression does not match any branch of the +case+ expression (and the +else+ branch is absent), +NoMatchingPatternError+ is raised.
+
+Therefore, the +case+ expression might be used for conditional matching and unpacking:
+
+  config = {db: {user: 'admin', password: 'abc123'}}
+
+  case config
+  in db: {user:} # matches subhash and puts matched value in variable user
+    puts "Connect with user '#{user}'"
+  in connection: {username: }
+    puts "Connect with user '#{username}'"
+  else
+    puts "Unrecognized structure of config"
+  end
+  # Prints: "Connect with user 'admin'"
+
+whilst the <code>=></code> operator is most useful when the expected data structure is known beforehand, to just unpack parts of it:
+
+  config = {db: {user: 'admin', password: 'abc123'}}
+
+  config => {db: {user:}} # will raise if the config's structure is unexpected
+
+  puts "Connect with user '#{user}'"
+  # Prints: "Connect with user 'admin'"
+
+<code><expression> in <pattern></code> is the same as <code>case <expression>; in <pattern>; true; else false; end</code>.
+You can use it when you only want to know if a pattern has been matched or not:
+
+  users = [{name: "Alice", age: 12}, {name: "Bob", age: 23}]
+  users.any? {|user| user in {name: /B/, age: 20..} } #=> true
+
+See below for more examples and explanations of the syntax.
+
+== Patterns
+
+Patterns can be:
+
+* any Ruby object (matched by the <code>===</code> operator, like in +when+); (<em>Value pattern</em>)
+* array pattern: <code>[<subpattern>, <subpattern>, <subpattern>, ...]</code>; (<em>Array pattern</em>)
+* find pattern: <code>[*variable, <subpattern>, <subpattern>, <subpattern>, ..., *variable]</code>; (<em>Find pattern</em>)
+* hash pattern: <code>{key: <subpattern>, key: <subpattern>, ...}</code>; (<em>Hash pattern</em>)
+* combination of patterns with <code>|</code>; (<em>Alternative pattern</em>)
+* variable capture: <code><pattern> => variable</code> or <code>variable</code>; (<em>As pattern</em>, <em>Variable pattern</em>)
+
+Any pattern can be nested inside array/find/hash patterns where <code><subpattern></code> is specified.
+
+Array patterns and find patterns match arrays, or objects that respond to +deconstruct+ (see below about the latter).
+Hash patterns match hashes, or objects that respond to +deconstruct_keys+ (see below about the latter). Note that only symbol keys are supported for hash patterns.
+
+An important difference between array and hash pattern behavior is that arrays match only a _whole_ array:
+
+  case [1, 2, 3]
+  in [Integer, Integer]
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "not matched"
+
+while the hash matches even if there are other keys besides the specified part:
+
+  case {a: 1, b: 2, c: 3}
+  in {a: Integer}
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+<code>{}</code> is the only exclusion from this rule. It matches only if an empty hash is given:
+
+  case {a: 1, b: 2, c: 3}
+  in {}
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "not matched"
+
+  case {}
+  in {}
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+There is also a way to specify there should be no other keys in the matched hash except those explicitly specified by the pattern, with <code>**nil</code>:
+
+  case {a: 1, b: 2}
+  in {a: Integer, **nil} # this will not match the pattern having keys other than a:
+    "matched a part"
+  in {a: Integer, b: Integer, **nil}
+    "matched a whole"
+  else
+    "not matched"
+  end
+  #=> "matched a whole"
+
+Both array and hash patterns support "rest" specification:
+
+  case [1, 2, 3]
+  in [Integer, *]
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+  case {a: 1, b: 2, c: 3}
+  in {a: Integer, **}
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+Parentheses around both kinds of patterns could be omitted:
+
+  case [1, 2]
+  in Integer, Integer
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+  case {a: 1, b: 2, c: 3}
+  in a: Integer
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+ [1, 2] => a, b
+ [1, 2] in a, b
+
+ {a: 1, b: 2, c: 3} => a:
+ {a: 1, b: 2, c: 3} in a:
+
+Find pattern is similar to array pattern but it can be used to check if the given object has any elements that match the pattern:
+
+  case ["a", 1, "b", "c", 2]
+  in [*, String, String, *]
+    "matched"
+  else
+    "not matched"
+  end
+
+== Variable binding
+
+Besides deep structural checks, one of the very important features of the pattern matching is the binding of the matched parts to local variables. The basic form of binding is just specifying <code>=> variable_name</code> after the matched (sub)pattern (one might find this similar to storing exceptions in local variables in a <code>rescue ExceptionClass => var</code> clause):
+
+  case [1, 2]
+  in Integer => a, Integer
+    "matched: #{a}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+  case {a: 1, b: 2, c: 3}
+  in a: Integer => m
+    "matched: #{m}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+If no additional check is required, for only binding some part of the data to a variable, a simpler form could be used:
+
+  case [1, 2]
+  in a, Integer
+    "matched: #{a}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+  case {a: 1, b: 2, c: 3}
+  in a: m
+    "matched: #{m}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+For hash patterns, even a simpler form exists: key-only specification (without any sub-pattern) binds the local variable with the key's name, too:
+
+  case {a: 1, b: 2, c: 3}
+  in a:
+    "matched: #{a}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+Binding works for nested patterns as well:
+
+  case {name: 'John', friends: [{name: 'Jane'}, {name: 'Rajesh'}]}
+  in name:, friends: [{name: first_friend}, *]
+    "matched: #{first_friend}"
+  else
+    "not matched"
+  end
+  #=> "matched: Jane"
+
+The "rest" part of a pattern also can be bound to a variable:
+
+  case [1, 2, 3]
+  in a, *rest
+    "matched: #{a}, #{rest}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1, [2, 3]"
+
+  case {a: 1, b: 2, c: 3}
+  in a:, **rest
+    "matched: #{a}, #{rest}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1, {:b=>2, :c=>3}"
+
+Binding to variables currently does NOT work for alternative patterns joined with <code>|</code>:
+
+  case {a: 1, b: 2}
+  in {a: } | Array
+    "matched: #{a}"
+  else
+    "not matched"
+  end
+  # SyntaxError (illegal variable in alternative pattern (a))
+
+Variables that start with <code>_</code> are the only exclusions from this rule:
+
+  case {a: 1, b: 2}
+  in {a: _, b: _foo} | Array
+    "matched: #{_}, #{_foo}"
+  else
+    "not matched"
+  end
+  # => "matched: 1, 2"
+
+It is, though, not advised to reuse the bound value, as this pattern's goal is to signify a discarded value.
+
+== Variable pinning
+
+Due to the variable binding feature, existing local variable can not be straightforwardly used as a sub-pattern:
+
+  expectation = 18
+
+  case [1, 2]
+  in expectation, *rest
+    "matched. expectation was: #{expectation}"
+  else
+    "not matched. expectation was: #{expectation}"
+  end
+  # expected: "not matched. expectation was: 18"
+  # real: "matched. expectation was: 1" -- local variable just rewritten
+
+For this case, the pin operator <code>^</code> can be used, to tell Ruby "just use this value as part of the pattern":
+
+  expectation = 18
+  case [1, 2]
+  in ^expectation, *rest
+    "matched. expectation was: #{expectation}"
+  else
+    "not matched. expectation was: #{expectation}"
+  end
+  #=> "not matched. expectation was: 18"
+
+One important usage of variable pinning is specifying that the same value should occur in the pattern several times:
+
+  jane = {school: 'high', schools: [{id: 1, level: 'middle'}, {id: 2, level: 'high'}]}
+  john = {school: 'high', schools: [{id: 1, level: 'middle'}]}
+
+  case jane
+  in school:, schools: [*, {id:, level: ^school}] # select the last school, level should match
+    "matched. school: #{id}"
+  else
+    "not matched"
+  end
+  #=> "matched. school: 2"
+
+  case john # the specified school level is "high", but last school does not match
+  in school:, schools: [*, {id:, level: ^school}]
+    "matched. school: #{id}"
+  else
+    "not matched"
+  end
+  #=> "not matched"
+
+In addition to pinning local variables, you can also pin instance, global, and class variables:
+
+  $gvar = 1
+  class A
+    @ivar = 2
+    @@cvar = 3
+    case [1, 2, 3]
+    in ^$gvar, ^@ivar, ^@@cvar
+      "matched"
+    else
+      "not matched"
+    end
+    #=> "matched"
+  end
+
+You can also pin the result of arbitrary expressions using parentheses:
+
+  a = 1
+  b = 2
+  case 3
+  in ^(a + b)
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+== Matching non-primitive objects: +deconstruct+ and +deconstruct_keys+
+
+As already mentioned above, array, find, and hash patterns besides literal arrays and hashes will try to match any object implementing +deconstruct+ (for array/find patterns) or +deconstruct_keys+ (for hash patterns).
+
+  class Point
+    def initialize(x, y)
+      @x, @y = x, y
+    end
+
+    def deconstruct
+      puts "deconstruct called"
+      [@x, @y]
+    end
+
+    def deconstruct_keys(keys)
+      puts "deconstruct_keys called with #{keys.inspect}"
+      {x: @x, y: @y}
+    end
+  end
+
+  case Point.new(1, -2)
+  in px, Integer  # sub-patterns and variable binding works
+    "matched: #{px}"
+  else
+    "not matched"
+  end
+  # prints "deconstruct called"
+  "matched: 1"
+
+  case Point.new(1, -2)
+  in x: 0.. => px
+    "matched: #{px}"
+  else
+    "not matched"
+  end
+  # prints: deconstruct_keys called with [:x]
+  #=> "matched: 1"
+
++keys+ are passed to +deconstruct_keys+ to provide a room for optimization in the matched class: if calculating a full hash representation is expensive, one may calculate only the necessary subhash. When the <code>**rest</code> pattern is used, +nil+ is passed as a +keys+ value:
+
+  case Point.new(1, -2)
+  in x: 0.. => px, **rest
+    "matched: #{px}"
+  else
+    "not matched"
+  end
+  # prints: deconstruct_keys called with nil
+  #=> "matched: 1"
+
+Additionally, when matching custom classes, the expected class can be specified as part of the pattern and is checked with <code>===</code>
+
+  class SuperPoint < Point
+  end
+
+  case Point.new(1, -2)
+  in SuperPoint(x: 0.. => px)
+    "matched: #{px}"
+  else
+    "not matched"
+  end
+  #=> "not matched"
+
+  case SuperPoint.new(1, -2)
+  in SuperPoint[x: 0.. => px] # [] or () parentheses are allowed
+    "matched: #{px}"
+  else
+    "not matched"
+  end
+  #=> "matched: 1"
+
+== Guard clauses
+
++if+ can be used to attach an additional condition (guard clause) when the pattern matches. This condition may use bound variables:
+
+  case [1, 2]
+  in a, b if b == a*2
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+  case [1, 1]
+  in a, b if b == a*2
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "not matched"
+
++unless+ works, too:
+
+  case [1, 1]
+  in a, b unless b == a*2
+    "matched"
+  else
+    "not matched"
+  end
+  #=> "matched"
+
+== Current feature status
+
+As of Ruby 3.1, find patterns are considered _experimental_: its syntax can change in the future. Every time you use these features in code, a warning will be printed:
+
+  [0] => [*, 0, *]
+  # warning: Find pattern is experimental, and the behavior may change in future versions of Ruby!
+  # warning: One-line pattern matching is experimental, and the behavior may change in future versions of Ruby!
+
+To suppress this warning, one may use the Warning::[]= method:
+
+  Warning[:experimental] = false
+  eval('[0] => [*, 0, *]')
+  # ...no warning printed...
+
+Note that pattern-matching warnings are raised at compile time, so this will not suppress the warning:
+
+  Warning[:experimental] = false # At the time this line is evaluated, the parsing happened and warning emitted
+  [0] => [*, 0, *]
+
+So, only subsequently loaded files or `eval`-ed code is affected by switching the flag.
+
+Alternatively, the command line option <code>-W:no-experimental</code> can be used to turn off "experimental" feature warnings.

+= Refinements
+
+Due to Ruby's open classes you can redefine or add functionality to existing
+classes.  This is called a "monkey patch".  Unfortunately the scope of such
+changes is global.  All users of the monkey-patched class see the same
+changes.  This can cause unintended side-effects or breakage of programs.
+
+Refinements are designed to reduce the impact of monkey patching on other
+users of the monkey-patched class.  Refinements provide a way to extend a
+class locally.  Refinements can modify both classes and modules.
+
+Here is a basic refinement:
+
+  class C
+    def foo
+      puts "C#foo"
+    end
+  end
+
+  module M
+    refine C do
+      def foo
+        puts "C#foo in M"
+      end
+    end
+  end
+
+First, a class +C+ is defined.  Next a refinement for +C+ is created using
+Module#refine.
+
+Module#refine creates an anonymous module that contains the changes or
+refinements to the class (+C+ in the example).  +self+ in the refine block is
+this anonymous module similar to Module#module_eval.
+
+Activate the refinement with #using:
+
+  using M
+
+  c = C.new
+
+  c.foo # prints "C#foo in M"
+
+== Scope
+
+You may activate refinements at top-level, and inside classes and modules.
+You may not activate refinements in method scope.  Refinements are activated
+until the end of the current class or module definition, or until the end of
+the current file if used at the top-level.
+
+You may activate refinements in a string passed to Kernel#eval. Refinements
+are active until the end of the eval string.
+
+Refinements are lexical in scope.  Refinements are only active within a scope
+after the call to +using+. Any code before the +using+ statement will not have the
+refinement activated.
+
+When control is transferred outside the scope, the refinement is deactivated.
+This means that if you require or load a file or call a method that is defined
+outside the current scope the refinement will be deactivated:
+
+  class C
+  end
+
+  module M
+    refine C do
+      def foo
+        puts "C#foo in M"
+      end
+    end
+  end
+
+  def call_foo(x)
+    x.foo
+  end
+
+  using M
+
+  x = C.new
+  x.foo       # prints "C#foo in M"
+  call_foo(x) #=> raises NoMethodError
+
+If a method is defined in a scope where a refinement is active, the refinement
+will be active when the method is called.  This example spans multiple files:
+
+c.rb:
+
+  class C
+  end
+
+m.rb:
+
+  require "c"
+
+  module M
+    refine C do
+      def foo
+        puts "C#foo in M"
+      end
+    end
+  end
+
+m_user.rb:
+
+  require "m"
+
+  using M
+
+  class MUser
+    def call_foo(x)
+      x.foo
+    end
+  end
+
+main.rb:
+
+  require "m_user"
+
+  x = C.new
+  m_user = MUser.new
+  m_user.call_foo(x) # prints "C#foo in M"
+  x.foo              #=> raises NoMethodError
+
+Since the refinement +M+ is active in <code>m_user.rb</code> where
+<code>MUser#call_foo</code> is defined it is also active when
+<code>main.rb</code> calls +call_foo+.
+
+Since #using is a method, refinements are only active when it is called.  Here
+are examples of where a refinement +M+ is and is not active.
+
+In a file:
+
+  # not activated here
+  using M
+  # activated here
+  class Foo
+    # activated here
+    def foo
+      # activated here
+    end
+    # activated here
+  end
+  # activated here
+
+In a class:
+
+  # not activated here
+  class Foo
+    # not activated here
+    def foo
+      # not activated here
+    end
+    using M
+    # activated here
+    def bar
+      # activated here
+    end
+    # activated here
+  end
+  # not activated here
+
+Note that the refinements in +M+ are *not* activated automatically if the class
++Foo+ is reopened later.
+
+In eval:
+
+  # not activated here
+  eval <<EOF
+    # not activated here
+    using M
+    # activated here
+  EOF
+  # not activated here
+
+When not evaluated:
+
+  # not activated here
+  if false
+    using M
+  end
+  # not activated here
+
+When defining multiple refinements in the same module inside multiple +refine+ blocks,
+all refinements from the same module are active when a refined method
+(any of the +to_json+ methods from the example below) is called:
+
+  module ToJSON
+    refine Integer do
+      def to_json
+        to_s
+      end
+    end
+
+    refine Array do
+      def to_json
+        "[" + map { |i| i.to_json }.join(",") + "]"
+      end
+    end
+
+    refine Hash do
+      def to_json
+        "{" + map { |k, v| k.to_s.dump + ":" + v.to_json }.join(",") + "}"
+      end
+    end
+  end
+
+  using ToJSON
+
+  p [{1=>2}, {3=>4}].to_json # prints "[{\"1\":2},{\"3\":4}]"
+
+
+== Method Lookup
+
+When looking up a method for an instance of class +C+ Ruby checks:
+
+* If refinements are active for +C+, in the reverse order they were activated:
+  * The prepended modules from the refinement for +C+
+  * The refinement for +C+
+  * The included modules from the refinement for +C+
+* The prepended modules of +C+
+* +C+
+* The included modules of +C+
+
+If no method was found at any point this repeats with the superclass of +C+.
+
+Note that methods in a subclass have priority over refinements in a
+superclass.  For example, if the method <code>/</code> is defined in a
+refinement for Numeric <code>1 / 2</code> invokes the original Integer#/
+because Integer is a subclass of Numeric and is searched before the refinements
+for the superclass Numeric. Since the method <code>/</code> is also present
+in child +Integer+, the method lookup does not move up to the superclass.
+
+However, if a method +foo+ is defined on Numeric in a refinement, <code>1.foo</code>
+invokes that method since +foo+ does not exist on Integer.
+
+== +super+
+
+When +super+ is invoked method lookup checks:
+
+* The included modules of the current class.  Note that the current class may
+  be a refinement.
+* If the current class is a refinement, the method lookup proceeds as in the
+  Method Lookup section above.
+* If the current class has a direct superclass, the method proceeds as in the
+  Method Lookup section above using the superclass.
+
+Note that +super+ in a method of a refinement invokes the method in the
+refined class even if there is another refinement which has been activated in
+the same context. This is only true for +super+ in a method of a refinement, it
+does not apply to +super+ in a method in a module that is included in a refinement.
+
+== Methods Introspection
+
+When using introspection methods such as Kernel#method or Kernel#methods refinements are not honored.
+
+This behavior may be changed in the future.
+
+== Refinement inheritance by Module#include
+
+When a module X is included into a module Y, Y inherits refinements from X.
+
+For example, C inherits refinements from A and B in the following code:
+
+  module A
+    refine X do ... end
+    refine Y do ... end
+  end
+  module B
+    refine Z do ... end
+  end
+  module C
+    include A
+    include B
+  end
+
+  using C
+  # Refinements in A and B are activated here.
+
+Refinements in descendants have higher precedence than those of ancestors.
+
+== Further Reading
+
+See https://bugs.ruby-lang.org/projects/ruby-master/wiki/RefinementsSpec for the
+current specification for implementing refinements.  The specification also
+contains more details.

+== Timezones
+
+=== Timezone Specifiers
+
+Certain \Time methods accept arguments that specify timezones:
+
+- Time.at: keyword argument +in:+.
+- Time.new: positional argument +zone+ or keyword argument +in:+.
+- Time.now: keyword argument +in:+.
+- Time#getlocal: positional argument +zone+.
+- Time#localtime: positional argument +zone+.
+
+The value given with any of these must be one of the following
+(each detailed below):
+
+- {Hours/minutes offset}[rdoc-ref:timezones.rdoc@Hours-2FMinutes+Offsets].
+- {Single-letter offset}[rdoc-ref:timezones.rdoc@Single-Letter+Offsets].
+- {Integer offset}[rdoc-ref:timezones.rdoc@Integer+Offsets].
+- {Timezone object}[rdoc-ref:timezones.rdoc@Timezone+Objects].
+
+==== Hours/Minutes Offsets
+
+The zone value may be a string offset from UTC
+in the form <tt>'+HH:MM'</tt> or <tt>'-HH:MM'</tt>,
+where:
+
+- +HH+ is the 2-digit hour in the range <tt>0..23</tt>.
+- +MM+ is the 2-digit minute in the range <tt>0..59</tt>.
+
+Examples:
+
+  t = Time.utc(2000, 1, 1, 20, 15, 1) # => 2000-01-01 20:15:01 UTC
+  Time.at(t, in: '-23:59')            # => 1999-12-31 20:16:01 -2359
+  Time.at(t, in: '+23:59')            # => 2000-01-02 20:14:01 +2359
+
+==== Single-Letter Offsets
+
+The zone value may be a  letter in the range <tt>'A'..'I'</tt>
+or <tt>'K'..'Z'</tt>;
+see {List of military time zones}[https://en.wikipedia.org/wiki/List_of_military_time_zones]:
+
+  t = Time.utc(2000, 1, 1, 20, 15, 1) # => 2000-01-01 20:15:01 UTC
+  Time.at(t, in: 'A')                 # => 2000-01-01 21:15:01 +0100
+  Time.at(t, in: 'I')                 # => 2000-01-02 05:15:01 +0900
+  Time.at(t, in: 'K')                 # => 2000-01-02 06:15:01 +1000
+  Time.at(t, in: 'Y')                 # => 2000-01-01 08:15:01 -1200
+  Time.at(t, in: 'Z')                 # => 2000-01-01 20:15:01 UTC
+
+==== \Integer Offsets
+
+The zone value may be an integer number of seconds
+in the range <tt>-86399..86399</tt>:
+
+  t = Time.utc(2000, 1, 1, 20, 15, 1) # => 2000-01-01 20:15:01 UTC
+  Time.at(t, in: -86399)              # => 1999-12-31 20:15:02 -235959
+  Time.at(t, in: 86399)               # => 2000-01-02 20:15:00 +235959
+
+==== Timezone Objects
+
+In most cases, the zone value may be an object
+responding to certain timezone methods.
+
+\Exceptions (timezone object not allowed):
+
+- Time.new with positional argument +zone+.
+- Time.now with keyword argument +in:+.
+
+The timezone methods are:
+
+- +local_to_utc+:
+
+  - Called when Time.new is invoked with +tz+
+    as the value of positional argument +zone+ or keyword argument +in:+.
+  - Argument: a <tt>Time::tm</tt> object.
+  - Returns: a \Time-like object in the UTC timezone.
+
+- +utc_to_local+:
+
+  - Called when Time.at or Time.now is invoked with +tz+
+    as the value for keyword argument +in:+,
+    and when Time#getlocal or Time#localtime is called with +tz+
+    as the value for positional argument +zone+.
+  - Argument: a <tt>Time::tm</tt> object.
+  - Returns: a \Time-like object in the local timezone.
+
+A custom timezone class may have these instance methods,
+which will be called if defined:
+
+- +abbr+:
+
+  - Called when Time#strftime is invoked with a format involving <tt>%Z</tt>.
+  - Argument: a <tt>Time::tm</tt> object.
+  - Returns: a string abbreviation for the timezone name.
+
+- +dst?+:
+
+  - Called when Time.at or Time.now is invoked with +tz+
+    as the value for keyword argument +in:+,
+    and when Time#getlocal or Time#localtime is called with +tz+
+    as the value for positional argument +zone+.
+  - Argument: a <tt>Time::tm</tt> object.
+  - Returns: whether the time is daylight saving time.
+
+- +name+:
+
+  - Called when <tt>Marshal.dump(t) is invoked
+  - Argument: none.
+  - Returns: the string name of the timezone.

+
+----
+
+* これは？
+
+[[YARV: Yet Another RubyVM|http://www.atdot.net/yarv]] の 設計メモです。
+
+
+YARV は、Ruby プログラムのための次の機能を提供します。
+
+- Compiler
+- VM Generator
+- VM (Virtual Machine)
+- Assembler
+- Dis-Assembler
+- (experimental) JIT Compiler
+- (experimental) AOT Compiler
+
+
+現在の YARV は Ruby インタプリタの拡張ライブラリとして実装しています。こ
+れにより、Ruby インタプリタの必要な機能（パーサ、オブジェクト管理、既存
+の拡張ライブラリ）などがほぼそのまま利用できます。
+
+ただし、いくつかのパッチを Ruby インタプリタに当てなければなりません。
+
+今後は、Ruby 本体のインタプリタ部分（eval.c）を置き換えることを目指して
+開発を継続する予定です。
+
+
+* Compiler (compile.h, compile.c)
+
+コンパイラは、Ruby インタプリタのパーサによって生成された構文木（RNode
+データによる木）を YARV 命令列に変換します。YARV 命令については後述しま
+す。
+
+とくに難しいことはしていませんが、スコープなどの開始時にローカル変数の初
+期化などを行い、あとは構文木を辿り変換していきます。
+
+変換中は Ruby の Array オブジェクトに YARV 命令オブジェクト、およびオペ
+ランドを格納していき、最後に実行できる形に変換します。コンパイラでは、コ
+ンパイル中に生成するメモリ領域の管理が問題になることがありますが、YARV
+の場合、Ruby インタプリタがすべて面倒をみてくれるのでこの部分は非常に楽
+に作ることができました（ガーベージコレクタによって自動的にメモリ管理をし
+てくれるため）。
+
+YARV 命令は、命令を示す識別子、オペランドなど、すべて 1 word （マシンで
+表現できる自然な値。C 言語ではポインタのサイズ。Ruby インタプリタ用語で
+は VALUE のサイズ）で表現されます。そのため、YARV 命令はいわゆる「バイト
+コード」ではありません。そのため、YARV の説明などでは「命令列」という用
+語を使っています。
+
+1 word であるため、メモリの利用効率は多少悪くなりますが、アクセス速度な
+どを考慮すると、本方式が一番いいと考えております。たとえばオペランドをコ
+ンスタントプールに格納し、インデックスのみをオペランドで示すことも可能で
+すが、間接アクセスになってしまうので性能に影響が出るため、却下しました。
+
+
+* VM Generator (rb/insns2vm.rb, insns.def)
+
+rb/insns2vm.rb というスクリプトは、insns.def というファイルを読み込み、
+VM のために必要なファイルを生成します。具体的には、命令を実行する部分を
+生成しますが、ほかにもコンパイルに必要な情報、最適化に必要な情報、やアセ
+ンブラ、逆アセンブラに必要な情報を示すファイルも生成します。
+
+
+** 命令記述
+
+insns.def には、各命令がどのような命令であるかを記述します。具体的には次
+の情報を記述します。
+
+- 命令の名前
+- その命令のカテゴリ、コメント（英語、日本語）
+- オペランドの名前
+- その命令実行前にスタックからポップする値
+- その命令実行後にスタックにプッシュする値
+- その命令のロジック（C 言語で記述）
+
+たとえば、スタックに self をおく putself という命令は次のように記述しま
+す。
+
+#code
+/**
+  @c put
+  @e put self.
+  @j self を置く。
+ */
+DEFINE_INSN
+putself
+()
+()
+(VALUE val)
+{
+  val = GET_SELF();
+}
+#end
+
+この場合、オペランドと、スタックからポップする値は無いことになります。命
+令終了後、self をスタックトップに置きたいわけですが、それは val という、
+スタックにプッシュする値として宣言しておいた変数に代入しておくことで、こ
+れを変換するとスタックトップに置く C プログラムが生成されます。
+
+細かいフォーマットは insns.def の冒頭を参照してください。そんなに難しく
+ないと思います。
+
+insnhelper.h というファイルに、命令ロジックを記述するために必要なマクロ
+が定義されています。また、VM の内部構造に関する定義は vm.h というファイ
+ルにあります。
+
+
+* VM (Virtual Machine, vm.h, vm.c)
+
+VM は、実際にコンパイルした結果生成される YARV 命令列を実行します。まさ
+に、この部分が YARV のキモになり、将来的には eval.c をこの VM で置き換え
+たいと考えています。
+
+現在の Ruby インタプリタで実行できるすべてのことが、この VM で実現できる
+ように作っています（現段階ではまだ完全ではありませんが、そうなるべきです）。
+
+VM は、単純なスタックマシンとして実装しています。スレッドひとつにスタッ
+クひとつを保持します。スタックの領域はヒープから取得するので、柔軟な領域
+設定が可能です。
+
+
+** レジスタ
+
+VM は 5 つの仮想的なレジスタによって制御されます。
+
+- PC (Program Counter)
+- SP (Stack Pointer)
+- CFP (Control Frame Pointer)
+- LFP (Local Frame Pointer)
+- DFP (Dynamic Frame Pointer)
+
+PC は現在実行中の命令列の位置を示します。SP はスタックトップの位置を示し
+ます。CFP、LFP、DFP はそれぞれフレームの情報を示します。詳細は後述します。
+
+
+** スタックフレーム
+
+obsolete (update soon)
+
+
+** フレームデザインについての補足
+
+Lisp の処理系などをかんがえると、わざわざブロックローカルフレームとメソ
+ッドローカルフレームのようなものを用意するのは奇異に見えるかもしれません。
+あるフレームを、入れ子構造にして、ローカル変数のアクセスはその入れ子を外
+側に辿れば必ずたどり着くことができるからです（つまり、lfp は必要ない）。
+
+しかし、Ruby ではいくつか状況が違います。まず、メソッドローカルな情報が
+あること、具体的にはブロックとself（callee からみると receiver）です。こ
+の情報をそれぞれのフレームにもたせるのは無駄です。
+
+また、Ruby2.0 からはブロックローカル変数はなくなります（ブロックローカル
+引数は残るので、構造自体はあまり変わりません）。そのため、メソッドローカ
+ル変数へのアクセスが頻発することが予想されます。
+
+このとき、メソッドローカル変数へのアクセスのたびにフレーム（スコープ）の
+リストをたどるのは無駄であると判断し、明示的にメソッドローカルスコープと
+ブロックフレームを分離し、ブロックフレームからはメソッドローカルフレーム
+が lfpレジスタによって容易にアクセスできるようにしました。
+
+
+** メソッド呼び出しについて
+
+メソッド呼び出しは、YARV 命令列で記述されたメソッドか、C で記述されたメ
+ソッドかによってディスパッチ手法が変わります。
+
+YARV 命令列であった場合、上述したスタックフレームを作成して命令を継続し
+ます。とくに VM の関数を再帰呼び出すすることは行ないません。
+
+C で記述されたメソッドだった場合、単純にその関数を呼び出します（ただし、
+バックトレースを正しく生成するためにメソッド呼び出しの情報を付加してから
+行ないます）。
+
+このため、VM 用スタックを別途用意したものの、プログラムによってはマシン
+スタックを使い切ってしまう可能性があります（C -> Ruby -> C -> ... という
+呼び出しが続いた場合）。これは、現在では避けられない仕様となっています。
+
+
+** 例外
+
+例外は、Java の JVM と同様に例外テーブルを用意することで実現します。例外
+が発生したら、当該フレームを、例外テーブルを検査します。そこで、例外が発
+生したときの PC の値に合致するエントリがあった場合、そのエントリに従って
+動作します。もしエントリが見つからなかった場合、スタックを撒き戻してまた
+同様にそのスコープの例外テーブルを検査します。
+
+また、break、return（ブロック中）、retry なども同様の仕組みで実現します。
+
+*** 例外テーブル
+
+例外テーブルエントリは具体的には次の情報が格納されています。
+
+- 対象とする PC の範囲
+- 対象とする例外の種類
+- もし対象となったときにジャンプする先（種類による）
+- もし対象となったときに起動するブロックの iseq
+
+
+*** rescue
+
+rescue 節はブロックとして実現しています。$! の値を唯一の引数として持ちま
+す。
+
+#code
+begin
+rescue A
+rescue B
+rescue C
+end
+#end
+
+は、次のような Ruby スクリプトに変換されます。
+
+#code
+{|err|
+  case err
+  when A === err
+  when B === err
+  when C === err
+  else
+    raise # yarv の命令では throw
+  end
+}
+#end
+
+
+*** ensure
+
+正常系（例外が発生しなかった場合）と異常系（例外が発生したときなど）の2
+種類の命令列が生成されます。正常系では、ただの連続したコード領域としてコ
+ンパイルされます。また、異常系ではブロックとして実装します。最後は必ず
+throw 命令で締めることになります。
+
+
+*** break, return（ブロック中）、retry
+
+break 文、ブロック中の return 文、retry 文は throw 命令としてコンパイル
+されます。どこまで戻るかは、break をフックする例外テーブルのエントリが判
+断します。
+
+
+** 定数の検索
+
+定数という名前なのに、Ruby ではコンパイル時に決定しません。というか、い
+つまでも再定義可能になっています。
+
+定数アクセスのためのRuby記述は次のようになります。
+
+#code
+Ruby表現:
+expr::ID::...::ID
+#end
+
+これは、yarv命令セットでは次のようになります。
+
+#code
+(expr)
+getconstant ID
+...
+getconstant ID
+#end
+
+
+*** 定数検索パス
+
+もし expr が nil だった場合、定数検索パスに従って定数を検索します。この
+挙動は今後 Ruby 2.0 に向けて変更される場合があります。
+
++ クラス、モジュールの動的ネスト関係（プログラムの字面上）をルートまで辿る
++ 継承関係をルート（Object）まで辿る
+
+このため、クラス、モジュールの動的ネスト関係を保存しなければなりません。
+このために、thread_object には klass_nest_stack というものを用意しました。
+これは、現在のネストの情報を保存します。
+
+メソッド定義時、その現在のネスト情報をメソッド定義時に（dupして）加える
+ことで、そのメソッドの実行時、そのネスト情報を参照することが可能になりま
+す。
+
+トップレベルでは、その情報はないことになります。
+
+クラス/モジュール定義文実行時は、現在の情報そのものを参照することになり
+ます。これは、クラススコープ突入時、その情報をクラス定義文にコピーします
+（すでにコピーされていれば、これを行いません）。
+
+これにより、動的なネスト情報を統一的に扱うことができます。
+
+
+** 最適化手法
+
+YARV では高速化を目的としているので、さまざまな最適化手法を利用していま
+す。詳細は割愛しますが、以下に述べる最適化などを行なっております。
+
+
+*** threaded code
+
+GCC の C 言語拡張である値としてのラベルを利用して direct threaded code
+を実現しています。
+
+
+*** Peephole optimization
+
+いくつかの簡単な最適化をしています。
+
+
+*** inline method cache
+
+命令列の中にメソッド検索結果を埋め込みます。
+
+
+*** inline constant cache
+
+命令列の中に定数検索結果を埋め込みます。
+
+
+*** ブロックと Proc オブジェクトの分離
+
+ブロック付きメソッド呼び出しが行なわれたときにはすぐにはブロックを Proc
+オブジェクトとして生成しません。これにより、必要ない Proc オブジェクトの
+生成を抑えています。
+
+Proc メソッドは、実際に必要になった時点で作られ、そのときに環境（スコー
+プ上に確保された変数など）をヒープに保存します。
+
+
+*** 特化命令
+
+Fixnum 同士の加算などを正直に関数呼び出しによって行なうと、コストがかか
+るので、これらのプリミティブな操作を行なうためのメソッド呼び出しは専用命
+令を用意しました。
+
+
+*** 命令融合
+
+複数の命令を 1 命令に変換します。融合命令は opt_insn_unif.def の記述によ
+り自動的に生成されます。
+
+
+*** オペランド融合
+
+複数のオペランドを含めた命令を生成します。融合命令は opt_operand.def の
+記述によって自動的に生成されます。
+
+
+*** stack caching
+
+スタックトップを仮想レジスタに保持するようにします。現在は 2 個の仮想レ
+ジスタを想定し、5状態のスタックキャッシングを行ないます。スタックキャッ
+シングする命令は自動的に生成されます。
+
+
+*** JIT Compile
+
+機械語を切り貼りします。非常に実験的なコードものしか作っておりません。ほ
+とんどのプログラムは動きません。
+
+
+*** AOT Compile
+
+YARV 命令列を C 言語に変換します。まだ十分な最適化を行なえておりませんが、
+それなりに動きます。rb/aotc.rb がコンパイラです。
+
+
+* Assembler (rb/yasm.rb)
+
+YARV 命令列のアセンブラを用意しました。使い方は rb/yasm.rb を参照してく
+ださい（まだ、例示してある生成手法のすべてをサポートしているわけではあり
+ません）。
+
+
+* Dis-Assembler (disasm.c)
+
+YARV 命令列を示すオブジェクト YARVCore::InstructionSequence には disasm
+メソッドがあります。これは、命令列を逆アセンブルした文字列を返します。
+
+
+* YARV 命令セット
+
+<%= d %>
+
+* その他
+
+** テスト
+
+test/test_* がテストケースです。一応、ミスなく動くはずです。逆にいうと、
+このテストに記述されている例ではきちんと動作するということです。
+
+
+** ベンチマーク
+
+benchmark/bm_* にベンチマークプログラムがおいてあります。
+
+
+** 今後の予定
+
+まだまだやらなければいけないこと、未実装部分がたくさんありますんでやって
+いかなければなりません。一番大きな目標は eval.c を置き換えることでしょう
+か。
+
+
+*** Verifier
+
+YARV 命令列は、ミスがあっても動かしてしまうため危険である可能性がありま
+す。そのため、スタックの利用状態をきちんと事前に検証するようなベリファイ
+アを用意しなければならないと考えています。
+
+
+*** Compiled File の構想
+
+Ruby プログラムをこの命令セットにシリアライズしたデータ構造をファイルに
+出力できるようにしたいと考えています。これを利用して一度コンパイルした命
+令列をファイルに保存しておけば、次回ロード時にはコンパイルの手間、コスト
+を省くことができます。
+
+
+**** 全体構成
+
+次のようなファイル構成を考えていますが、まだ未定です。
+
+#code
+u4 : 4 byte unsigned storage
+u2 : 2 byte unsigned storage
+u1 : 1 byte unsigned storage
+
+every storages are little endian :-)
+
+CompiledFile{
+  u4 magic;
+
+  u2 major;
+  u2 minor;
+
+  u4 character_code;
+
+  u4 constants_pool_count;
+  ConstantEntry constants_pool[constants_pool_count];
+
+  u4 block_count;
+  blockEntry blocks[block_count];
+
+  u4 method_count;
+  MethodEntry methods[method_count];
+}
+#end

+YJIT - Yet Another Ruby JIT
+===========================
+
+YJIT is a lightweight, minimalistic Ruby JIT built inside CRuby.
+It lazily compiles code using a Basic Block Versioning (BBV) architecture.
+The target use case is that of servers running Ruby on Rails.
+YJIT is currently supported for macOS, Linux and BSD on x86-64 and arm64/aarch64 CPUs.
+This project is open source and falls under the same license as CRuby.
+
+<p align="center"><b>

+
+## Current Limitations
+
+YJIT may not be suitable for certain applications. It currently only supports macOS and Linux on x86-64 and arm64/aarch64 CPUs. YJIT will use more memory than the Ruby interpreter because the JIT compiler needs to generate machine code in memory and maintain additional state information.
+You can change how much executable memory is allocated using [YJIT's command-line options](#command-line-options). There is a slight performance tradeoff because allocating less executable memory could result in the generated machine code being collected more often.
+
+## Installation
+
+### Requirements
+
+You will need to install:
+- A C compiler such as GCC or Clang
+- GNU Make and Autoconf
+- The Rust compiler `rustc` and Cargo (if you want to build in dev/debug mode)
+  - The Rust version must be [>= 1.58.0](../../yjit/Cargo.toml).
+
+To install the Rust build toolchain, we suggest following the [recommended installation method][rust-install]. Rust also provides first class [support][editor-tools] for many source code editors.
+
+[rust-install]: https://www.rust-lang.org/tools/install
+[editor-tools]: https://www.rust-lang.org/tools
+
+### Building YJIT
+
+Start by cloning the `ruby/ruby` repository:
+
+```sh
+git clone https://github.com/ruby/ruby yjit
+cd yjit
+```
+
+The YJIT `ruby` binary can be built with either GCC or Clang. It can be built either in dev (debug) mode or in release mode. For maximum performance, compile YJIT in release mode with GCC. More detailed build instructions are provided in the [Ruby README](https://github.com/ruby/ruby#how-to-build).
+
+```sh
+# Configure in release mode for maximum performance, build and install
+./autogen.sh
+./configure --enable-yjit --prefix=$HOME/.rubies/ruby-yjit --disable-install-doc
+make -j && make install
+```
+
+or
+
+```sh
+# Configure in lower-performance dev (debug) mode for development, build and install
+./autogen.sh
+./configure --enable-yjit=dev --prefix=$HOME/.rubies/ruby-yjit --disable-install-doc
+make -j && make install
+```
+
+Dev mode includes extended YJIT statistics, but can be slow. For only statistics you can configure in stats mode:
+
+```sh
+# Configure in extended-stats mode without slow runtime checks, build and install
+./autogen.sh
+./configure --enable-yjit=stats --prefix=$HOME/.rubies/ruby-yjit --disable-install-doc
+make -j && make install
+```
+
+On macOS, you may need to specify where to find some libraries:
+
+```sh
+# Install dependencies
+brew install openssl readline libyaml
+
+# Configure in dev (debug) mode for development, build and install
+./autogen.sh
+./configure --enable-yjit=dev --prefix=$HOME/.rubies/ruby-yjit --disable-install-doc --with-opt-dir="$(brew --prefix openssl):$(brew --prefix readline):$(brew --prefix libyaml)"
+make -j && make install
+```
+
+Typically configure will choose the default C compiler. To specify the C compiler, use
+
+```sh
+# Choosing a specific c compiler
+export CC=/path/to/my/chosen/c/compiler
+```
+
+before running `./configure`.
+
+You can test that YJIT works correctly by running:
+
+```sh
+# Quick tests found in /bootstraptest
+make btest
+
+# Complete set of tests
+make -j test-all
+```
+
+## Usage
+
+### Examples
+
+Once YJIT is built, you can either use `./miniruby` from within your build directory, or switch to the YJIT version of `ruby`
+by using the `chruby` tool:
+
+```sh
+chruby ruby-yjit
+ruby myscript.rb
+```
+
+You can dump statistics about compilation and execution by running YJIT with the `--yjit-stats` command-line option:
+
+```sh
+./miniruby --yjit-stats myscript.rb
+```
+
+The machine code generated for a given method can be printed by adding `puts RubyVM::YJIT.disasm(method(:method_name))` to a Ruby script. Note that no code will be generated if the method is not compiled.
+
+### Command-Line Options
+
+YJIT supports all command-line options supported by upstream CRuby, but also adds a few YJIT-specific options:
+
+- `--yjit`: enable YJIT (disabled by default)
+- `--yjit-call-threshold=N`: number of calls after which YJIT begins to compile a function (default 30)
+- `--yjit-exec-mem-size=N`: size of the executable memory block to allocate, in MiB (default 64 MiB)
+- `--yjit-stats`: print statistics after the execution of a program (incurs a run-time cost)
+- `--yjit-trace-exits`: produce a Marshal dump of backtraces from specific exits. Automatically enables `--yjit-stats`
+
+Note that there is also an environment variable `RUBY_YJIT_ENABLE` which can be used to enable YJIT.
+This can be useful for some deployment scripts where specifying an extra command-line option to Ruby is not practical.
+
+### Benchmarking
+
+We have collected a set of benchmarks and implemented a simple benchmarking harness in the [yjit-bench](https://github.com/Shopify/yjit-bench) repository. This benchmarking harness is designed to disable CPU frequency scaling, set process affinity and disable address space randomization so that the variance between benchmarking runs will be as small as possible. Please kindly note that we are at an early stage in this project.
+
+## Performance Tips for Production Deployments
+
+While YJIT options default to what we think would work well for most workloads,
+they might not necessarily be the best configuration for your application.
+
+This section covers tips on improving YJIT performance in case YJIT does not
+speed up your application in production.
+
+### Increasing --yjit-exec-mem-size
+
+When JIT code size (`RubyVM::YJIT.runtime_stats[:code_region_size]`) reaches this value,
+YJIT triggers "code GC" that frees all JIT code and starts recompiling everything.
+Compiling code takes some time, so scheduling code GC too frequently slows down your application.
+Increasing `--yjit-exec-mem-size` may speed up your application if `RubyVM::YJIT.runtime_stats[:code_gc_count]` is not 0 or 1.
+
+### Running workers as long as possible
+
+It's helpful to call the same code as many times as possible before a process restarts.
+If a process is killed too frequently, the time taken for compiling methods may outweigh
+the speedup obtained by compiling them.
+
+You should monitor the number of requests each process has served.
+If you're periodically killing worker processes, e.g. with `unicorn-worker-killer` or `puma_worker_killer`,
+you may want to reduce the killing frequency or increase the limit.
+
+## Saving YJIT Memory Usage
+
+YJIT allocates memory for JIT code and metadata. Enabling YJIT generally results in more memory usage.
+
+This section goes over tips on minimizing YJIT memory usage in case it uses more than your capacity.
+
+### Increasing --yjit-call-threshold
+
+As of Ruby 3.2, `--yjit-call-threshold` defaults to 30. With this default, some applications end up
+compiling methods that are used only during the application boot. Increasing this option may help
+you reduce the size of JIT code and metadata. It's worth trying different values like `--yjit-call-threshold=100`.
+
+Note that increasing the value too much may result in compiling code too late.
+You should monitor how many requests each worker processes before it's restarted. For example,
+if each process only handles 1000 requests, `--yjit-call-threshold=1000` might be too large for your application.
+
+### Decreasing --yjit-exec-mem-size
+
+`--yjit-exec-mem-size` specifies the JIT code size, but YJIT also uses memory for its metadata,
+which often consumes more memory than JIT code. Generally, YJIT adds memory overhead by roughly
+3-4x of `--yjit-exec-mem-size` in production as of Ruby 3.2. You should multiply that by the number
+of worker processes to estimate the worst case memory overhead.
+
+Running code GC adds overhead, but it could be still faster than recovering from a whole process killed by OOM.
+
+## Code Optimization Tips
+
+This section contains tips on writing Ruby code that will run as fast as possible on YJIT. Some of this advice is based on current limitations of YJIT, while other advice is broadly applicable. It probably won't be practical to apply these tips everywhere in your codebase. You should ideally start by profiling your application using a tool such as [stackprof](https://github.com/tmm1/stackprof) so that you can determine which methods make up most of the execution time. You can then refactor the specific methods that make up the largest fractions of the execution time. We do not recommend modifying your entire codebase based on the current limitations of YJIT.
+
+- Avoid using `OpenStruct`
+- Avoid redefining basic integer operations (i.e. +, -, <, >, etc.)
+- Avoid redefining the meaning of `nil`, equality, etc.
+- Avoid allocating objects in the hot parts of your code
+- Minimize layers of indirection
+  - Avoid classes that wrap objects if you can
+  - Avoid methods that just call another method, trivial one liner methods
+- Try to write code so that the same variables always have the same type
+- Use `while` loops if you can, instead of C methods like `Array#each`
+  - This is not idiomatic Ruby, but could help in hot methods
+- CRuby method calls are costly. Avoid things such as methods that only return a value from a hash or return a constant.
+
+You can also use the `--yjit-stats` command-line option to see which bytecodes cause YJIT to exit, and refactor your code to avoid using these instructions in the hottest methods of your code.
+
+### Other Statistics
+
+If you run `ruby` with `--yjit --yjit-stats`, YJIT will track and return performance statistics in `RubyVM::YJIT.runtime_stats`.
+
+```rb
+$ RUBYOPT="--yjit --yjit-stats" irb
+irb(main):001:0> RubyVM::YJIT.runtime_stats
+=>
+{:inline_code_size=>340745,
+ :outlined_code_size=>297664,
+ :all_stats=>true,
+ :exec_instruction=>1547816,
+ :send_callsite_not_simple=>7267,
+ :send_kw_splat=>7,
+ :send_ivar_set_method=>72,
+...
+```
+
+Some of the counters include:
+
+* :exec_instruction - how many Ruby bytecode instructions have been executed
+* :binding_allocations - number of bindings allocated
+* :binding_set - number of variables set via a binding
+* :code_gc_count - number of garbage collections of compiled code since process start
+* :vm_insns_count - number of instructions executed by the Ruby interpreter
+* :compiled_iseq_count - number of bytecode sequences compiled
+* :inline_code_size - size in bytes of compiled YJIT blocks
+* :outline_code_size - size in bytes of YJIT error-handling compiled code
+* :side_exit_count - number of side exits taken at runtime
+* :total_exit_count - number of exits, including side exits, taken at runtime
+* :avg_len_in_yjit - avg. number of instructions in compiled blocks before exiting to interpreter
+
+Counters starting with "exit_" show reasons for YJIT code taking a side exit (return to the interpreter.) See yjit_hacking.md for more details.
+
+Performance counter names are not guaranteed to remain the same between Ruby versions. If you're curious what one does, it's usually best to search the source code for it &mdash; but it may change in a later Ruby version.
+
+The printed text after a --yjit-stats run includes other information that may be named differently than the information in runtime_stats.
+
+## Contributing
+
+We welcome open source contributors. You should feel free to open new issues to report bugs or just to ask questions.
+Suggestions on how to make this readme file more helpful for new contributors are most welcome.
+
+Bug fixes and bug reports are very valuable to us. If you find a bug in YJIT, it's very possible be that nobody has reported it before,
+or that we don't have a good reproduction for it, so please open an issue and provide as much information as you can about your configuration and a description of how you encountered the problem. List the commands you used to run YJIT so that we can easily reproduce the issue on our end and investigate it. If you are able to produce a small program reproducing the error to help us track it down, that is very much appreciated as well.
+
+If you would like to contribute a large patch to YJIT, we suggest opening an issue or a discussion on this repository so that
+we can have an active discussion. A common problem is that sometimes people submit large pull requests to open source projects
+without prior communication, and we have to reject them because the work they implemented does not fit within the design of the
+project. We want to save you time and frustration, so please reach out and we can have a productive discussion as to how
+you can contribute things we will want to merge into YJIT.
+
+### Source Code Organization
+
+The YJIT source code is divided between:
+- `yjit.c`: code YJIT uses to interface with the rest of CRuby
+- `yjit.h`: C definitions YJIT exposes to the rest of the CRuby
+- `yjit.rb`: `YJIT` Ruby module that is exposed to Ruby
+- `yjit/src/asm/*`: in-memory assembler we use to generate machine code
+- `yjit/src/codegen.rs`: logic for translating Ruby bytecode to machine code
+- `yjit/src/core.rb`: basic block versioning logic, core structure of YJIT
+- `yjit/src/stats.rs`: gathering of run-time statistics
+- `yjit/src/options.rs`: handling of command-line options
+- `yjit/bindgen/src/main.rs`: C bindings exposed to the Rust codebase through bindgen
+- `yjit/src/cruby.rs`: C bindings manually exposed to the Rust codebase
+
+The core of CRuby's interpreter logic is found in:
+- `insns.def`: defines Ruby's bytecode instructions (gets compiled into `vm.inc`)
+- `vm_insnshelper.c`: logic used by Ruby's bytecode instructions
+- `vm_exec.c`: Ruby interpreter loop
+
+### Generating C bindings with bindgen
+
+In order to expose C functions to the Rust codebase, you will need to generate C bindings:
+
+```sh
+CC=clang ./configure --enable-yjit=dev
+make -j yjit-bindgen
+```
+
+This uses the bindgen tools to generate/update `yjit/src/cruby_bindings.inc.rs` based on the
+bindings listed in `yjit/bindgen/src/main.rs`. Avoid manually editing this file
+as it could be automatically regenerated at a later time. If you need to manually add C bindings,
+add them to `yjit/cruby.rs` instead.
+
+### Coding & Debugging Protips
+
+There are 3 test suites:
+- `make btest` (see `/bootstraptest`)
+- `make test-all`
+- `make test-spec`
+- `make check` runs all of the above
+
+The tests can be run in parallel like this:
+
+```sh
+make -j test-all RUN_OPTS="--yjit-call-threshold=1"
+```
+
+Or single-threaded like this, to more easily identify which specific test is failing:
+
+```sh
+make test-all TESTOPTS=--verbose RUN_OPTS="--yjit-call-threshold=1"
+```
+
+To debug a single test in `test-all`:
+
+```sh
+make test-all TESTS='test/-ext-/marshal/test_usrmarshal.rb' RUNRUBYOPT=--debugger=lldb RUN_OPTS="--yjit-call-threshold=1"
+```
+
+You can also run one specific test in `btest`:
+
+```sh
+make btest BTESTS=bootstraptest/test_ractor.rb RUN_OPTS="--yjit-call-threshold=1"
+```
+
+There are shortcuts to run/debug your own test/repro in `test.rb`:
+
+```sh
+make run  # runs ./miniruby test.rb
+make lldb # launches ./miniruby test.rb in lldb
+```
+
+You can use the Intel syntax for disassembly in LLDB, keeping it consistent with YJIT's disassembly:
+
+```sh
+echo "settings set target.x86-disassembly-flavor intel" >> ~/.lldbinit
+```
+
+## Running x86 YJIT on Apple's Rosetta
+
+For development purposes, it is possible to run x86 YJIT on an Apple M1 via Rosetta.  You can find basic
+instructions below, but there are a few caveats listed further down.
+
+First, install Rosetta:
+
+```sh
+$ softwareupdate --install-rosetta
+```
+
+Now any command can be run with Rosetta via the `arch` command line tool.
+
+Then you can start your shell in an x86 environment:
+
+```sh
+$ arch -x86_64 zsh
+```
+
+You can double check your current architecture via the `arch` command:
+
+```sh
+$ arch -x86_64 zsh
+$ arch
+i386
+```
+
+You may need to set the default target for `rustc` to x86-64, e.g.
+
+```sh
+$ rustup default stable-x86_64-apple-darwin
+```
+
+While in your i386 shell, install Cargo and Homebrew, then hack away!
+
+### Rosetta Caveats
+
+1. You must install a version of Homebrew for each architecture
+2. Cargo will install in $HOME/.cargo by default, and I don't know a good way to change architectures after install
+
+If you use Fish shell you can [read this link](https://tenderlovemaking.com/2022/01/07/homebrew-rosetta-and-ruby.html) for information on making the dev environment easier.

+# YJIT Hacking
+
+## Code Generation and Assembly Language
+
+YJIT’s basic purpose is to take ISEQs and generate machine code.
+
+Documentation on each Ruby bytecode can be found in insns.def.
+
+YJIT uses those bytecodes as the “Basic Blocks” in Lazy Basic Block Versioning (LBBV.) For more deep details of LBBV, see yjit.md in this directory.
+
+Current YJIT has a simple assembler as a backend. Each method that generates code does it by emitting machine code:
+
+```
+# Excerpt of yjit_gen_exit() from yjit_codegen.c, Sept 2021
+// Generate an exit to return to the interpreter
+static uint32_t
+yjit_gen_exit(VALUE *exit_pc, ctx_t *ctx, codeblock_t *cb)
+{
+    const uint32_t code_pos = cb->write_pos;
+
+    ADD_COMMENT(cb, "exit to interpreter");
+
+    // Generate the code to exit to the interpreters
+    // Write the adjusted SP back into the CFP
+    if (ctx->sp_offset != 0) {
+        x86opnd_t stack_pointer = ctx_sp_opnd(ctx, 0);
+        lea(cb, REG_SP, stack_pointer);
+        mov(cb, member_opnd(REG_CFP, rb_control_frame_t, sp), REG_SP);
+    }
+
+    // Update CFP->PC
+    mov(cb, RAX, const_ptr_opnd(exit_pc));
+    mov(cb, member_opnd(REG_CFP, rb_control_frame_t, pc), RAX);
+```
+
+Later there will be a more complex backend.
+
+## Code Generation vs Code Execution
+
+When you see lea() call above (“load effective address,”) it’s not running the LEA x86 instruction. It’s generating an LEA instruction to the codeblock pointer in the first argument. It will execute that instruction later, when the codeblock gets executed.
+
+This is subtle because YJIT will often wait to compile the method until you’re about to run it -- that’s when it knows the most about what types of arguments the method will receive. So it’s a compile-time instruction, but often it will defer compile-time until just barely before runtime.
+
+The ctx structure tracks what is known at compile time about the arguments being passed into the Ruby bytecode. Often YJIT will “peek” at an expected type before it generates machine code.
+
+## Inlined and Outlined Code
+
+When YJIT is generating code, it needs a code pointer. In many cases it needs two, usually called “cb” (codeblock) and “ocb” (out-of-line codeblock.)
+
+cb is for “inlined” normal code and ocb is for “outline” code such as exits. Inlined code is normal generated code for Ruby operations, while outlined code is for unusual and error conditions, such as encountering an unexpected parameter type and exiting to the interpreter.
+
+The purpose of the outlined code block is to keep things we believe are going to be infrequent somewhere else. That way we can keep the code in the inline block more linear and compact. Linear code, with as few branches as possible, is more easily predicted by the CPU. An exception or unsupported operation will cause YJIT to generate outlined code to handle it.
+
+If you search for ocb in yjit_codegen.c, you can see some places where out-of-line code is generated.
+
+YJIT statistics are only gathered when RUBY_DEBUG or YJIT_STATS is true. In some cases the code to increment YJIT statistics will be generated out-of-line, especially if those statistics are gathered when a side exit happens.
+
+## Statistics and Comments
+
+When RUBY_DEBUG is defined to a true value, YJIT will emit comments into the generated machine code. This can make disassemblies a lot more readable. When RUBY_DEBUG or YJIT_STATS is defined and stats are active (--yjit-stats or export YJIT_STATS=1), code will be generated to collect statistics during the run, and a report will be printed when the process exits.
+
+## Entering and Exiting the Interpreter
+
+YJIT won’t generate machine code for an ISEQ until it’s been run a certain number of times (10 by default.) Then, the next time the interpreter would call that ISEQ, it will call the generated machine code version instead. If YJIT hits an unexpected or unsupported operation, it will return to the normal interpreter.
+
+If YJIT returns to the interpreter, the behaviour will be correct but slower. YJIT only optimises part of some operations - for instance, YJIT will not optimise a BMETHOD call yet.
+
+When the interpreter calls to a YJIT-optimised method again, control will return to YJIT’s generated machine code. The more time that’s spent in YJIT-generated code (“ratio in YJIT,”) the more CPU time YJIT can save with its optimisations.
+
+## Side Exits
+
+When YJIT has compiled an ISEQ and is running it later, sometimes it will hit an unexpected condition. It might see a parameter of a different type than before, or square-brackets might be used on a hash when they were first used on an array. In those cases, the generated code will contain a call to return to the interpreter at runtime, called a “side exit.”
+
+Side exits are generated as out-of-line code.
