- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+ c) give non-standard binaries non-standard names, with
+ instructions on where to get the original software distribution.
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
+ d) make other distribution arrangements with the author.
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+ 3. You may distribute the software in object code or binary form,
+ provided that you do at least ONE of the following:
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+ a) distribute the binaries and library files of the software,
+ together with instructions (in the manual page or equivalent)
+ on where to get the original distribution.
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
+ b) accompany the distribution with the machine-readable source of
+ the software.
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+ c) give non-standard binaries non-standard names, with
+ instructions on where to get the original software distribution.
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
+ d) make other distribution arrangements with the author.
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
+ 4. You may modify and include the part of the software into any other
+ software (possibly commercial). But some files in the distribution
+ are not written by the author, so that they are not under these terms.
- 1. You may copy and distribute verbatim copies of the Program's
-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 give any other recipients of the Program a copy of this License
-along with the Program.
+ For the list of those files and their copying conditions, see the
+ file LEGAL.
-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.
+ 5. The scripts and library files supplied as input to or produced as
+ output from the software do not automatically fall under the
+ copyright of the software, but belong to whomever generated them,
+ and may be sold commercially, and may be aggregated with this
+ software.
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-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 Program, 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 Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) 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; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, 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 executable. However, as a
-special exception, the source code 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.
-
-If distribution of executable or 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 counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program 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.
-
- 5. 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 Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program 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 to
-this License.
-
- 7. 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 Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program 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 Program.
-
-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.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program 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.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the 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 Program
-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 Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, 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
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), 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 Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. 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 program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program 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 General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; 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.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.
+ 6. THIS SOFTWARE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+ IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED

+ webrick: do not hang acceptor on slow TLS connections
- * hash.c (rb_any_cmp): Fixed return without value.
+ OpenSSL::SSL::SSLSocket#accept may block indefinitely on clients
+ which negotiate the TCP connection, but fail (or are slow) to
+ negotiate the subsequent TLS handshake. This prevents the
+ multi-threaded WEBrick server from accepting other connections.
-Tue Nov 9 13:21:04 1999 EGUCHI Osamu <eguchi@shizuokanet.ne.jp>
+ Since the TLS handshake (via OpenSSL::SSL::SSLSocket#accept)
+ consists of normal read/write traffic over TCP, handle it in the
+ per-client thread, instead.
- * configure.in: AC_MINIX move to before AC_EXEEXT and AC_OBJEXT.
+ Furthermore, using non-blocking accept() is useful for non-TLS
+ sockets anyways because spurious wakeups are possible from
+ select(2).

- * configure.in: Renamed AC_CHAR_UNSIGNED to AC_C_CHAR_UNSIGNED.
+ webrick: fix up r60172
- * configure.in: Added default to AC_CHECK_SIZEOF().
+ By making the socket non-blocking in r60172, TLS/SSL negotiation
+ via the SSL_accept function must handle non-blocking sockets
+ properly and retry on SSL_ERROR_WANT_READ/SSL_ERROR_WANT_WRITE.
+ OpenSSL::SSL::SSLSocket#accept cannot do that properly with a
+ non-blocking socket, so it must use non-blocking logic of
+ OpenSSL::SSL::SSLSocket#accept_nonblock.

+ For example, this method is useful to test iseq dumper/loader

+
+ * vm_method.c (rb_class_clear_method_cache): should clear all

+
+ * rb_method_definition_t::complemented_count to count shared method
+ entries because of complemented method entries and separate from
+ alias_count.
+
+ Shared `def' only by complemented method entries should not prevent
+ method re-definition warning.
+
+ * METHOD_ENTRY_COMPLEMENTED(me) to represent complemented method entry.
+ * METHOD_ENTRY_COMPLEMENTED_SET(me) to check it as complemented me.
+
+ * vm_insnhelper.c (aliased_callable_method_entry): should also
+ check me->def->complemented_count.
+
+ * vm_method.c (method_definition_addref_complement): add to count
+ complemented method entries number.

+
+ * 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.

+
+ * 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
+ because these operations break object relations consistency.
+
+ 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.

+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, 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 or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+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 give any other recipients of the Program a copy of this License
+along with the Program.
+
+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 Program or any portion
+of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+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 Program, 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 Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) 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; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, 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 executable. However, as a
+special exception, the source code 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.
+
+If distribution of executable or 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 counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program 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.
+
+ 5. 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 Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program 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 to
+this License.
+
+ 7. 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 Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program 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 Program.
+
+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.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program 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.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 Program
+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 Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, 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
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), 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 Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. 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 program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program 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 General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+= NEWS for Ruby 2.3.0
+
+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 2.2.0 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.
+ 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
+ [Feature #11537]
+
+* the did_you_mean gem:
+
+ * When a NameError or NoMethodError occurs because of a typo in the name,
+ the did_you_mean gem automatically suggests other names similar to the
+ method name.
+
+ "Yuki".starts_with?("Y")
+ # => NoMethodError: undefined method `starts_with?' for "Yuki":String
+ # Did you mean? start_with?
+
+* indented here document:
+
+ * new string literal, here document starts with `<<~`.
+ refer doc/syntax/literals.rdoc for more details.
+ [Feature #9098]
+

+ block is called. [Feature #10714]
+
+ * Array#flatten and Array#flatten! no longer try to call #to_ary
+ method on elements beyond the given level. [Bug #10748]
+
+ * Array#inspect doesn't raise error even if its content returns
+ a string which is not compatible with Encoding.default_external
+ as inspected result. [Feature #11801]
+
+* Enumerable
+ * Enumerable#chunk and Enumerable#slice_before no longer takes the
+ initial_state argument. [Feature #10958]
+ Use a local variable instead to maintain a state.
+
+* File::Stat
+ * On Windows File::Stat#ino always returned 0, but now returns
+ BY_HANDLE_FILE_INFORMATION.nFileIndexHigh/Low. [Feature #11216]
+
+* Hash

+ a string which is not compatible with Encoding.default_external
+ as inspected result. [Feature #11801]
+
+* IO
+ * IO#close doesn't raise when the IO object is closed. [Feature #10718]
+ * IO#each_codepoint raises an exception at incomplete character
+ before EOF when conversion takes place. [Bug #11444]

+ [Feature #10532] [Feature #11229]
+ * BasicSocket#recv and BasicSocket#recv_nonblock allow an output
+ String buffer argument like IO#read and IO#read_nonblock to reduce
+ GC overhead [Feature #11242]
+
+* StringIO
+ * In read-only mode, StringIO#set_encoding no longer sets the encoding
+ of its buffer string. Setting the encoding of the string directly
+ without StringIO#set_encoding may cause unpredictable behavior now.
+ [Bug #11827]

+
+=== 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]
+
+* rb_time_timespec_new() is added to create a time object with epoch,

+
+=== Supported platform changes
+
+* 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
+ 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 extention.

-* 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.netlab.co.jp/pub/lang/ruby/
-
-You can get it by anonymous CVS. How to check out is:
-
- $ cvs -d :pserver:anonymous@cvs.netlab.co.jp:/home/cvs login
- (Logging in to anonymous@cvs.netlab.co.jp)
- CVS password: guest
- $ cvs -d :pserver:anonymous@cvs.netlab.co.jp:/home/cvs checkout ruby
-
-* 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@netlab.co.jp>.
-
-* How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
- 1. Run ./configure, which will generate config.h and Makefile.
-
- 2. Edit defines.h if you need. Probably this step will not need.
-
- 3. 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.
-
- 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'
-
- 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.

-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 static type and data themselves have
-types. So, data need to be converted across the languages.
-
-Data in Ruby represented C type `VALUE'. Each VALUE data have its
-data-type.
-
-To retrieve an C data from the VALUE, you need to:
-
- (1) Identify VALUE's data type
- (2) Convert VALUE into C data
-
-Converting to wrong data type may cause serious problems.
-
-
-1.1 Data-types
-
-Ruby interpreter has data-types as below:
-
- 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_TRUE true
- T_FALSE false
- T_DATA data
-
-Otherwise, there are several other types used internally:
-
- T_ICLASS
- T_MATCH
- 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 data-type of the VALUE.
-TYPE() returns the constant number T_XXXX described above. To handle
-data-types, the code will be like:
-
- switch (TYPE(obj)) {
- case T_FIXNUM:
- /* process Fixnum */
- break;
- case T_STRING:
- /* process String */
- break;
- case T_ARRAY:
- /* process Array */
- break;
- default:
- /* raise exception */
- Fail("not valid value");
- break;
- }
-
-There is the data-type check function.
-
- void Check_Type(VALUE value, int type)
-
-It raises an exception, if the VALUE does not have the type specified.
-
-There are 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 the 31bit length fixed integer (63bit length on
-some machines), which can be convert to the C integer by using
-FIX2INT() macro. There also be NUM2INT() which converts any Ruby
-numbers into C integer. The NUM2INT() macro includes type check, so
-the exception will be raised if conversion failed.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. VALUE of the type which has corresponding structure
-can be cast to retrieve the pointer to the struct. The casting macro
-RXXXX for each data type like RARRAY(obj). see "ruby.h".
-
-For example, `RSTRING(size)->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, `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible about the result. It will be the cause of interesting
-bugs.
-
-1.4 Convert C data into VALUE
-
-To convert C data to the values of Ruby:
-
- * FIXNUM
-
- left shift 1 bit, and turn on LSB.
-
- * Other pointer values
-
- cast to VALUE.
-
-You can determine whether VALUE is pointer or not, by checking LSB.
-
-Notice Ruby does not allow arbitrary pointer value to be VALUE. They
-should be pointers to the structures which Ruby knows. The known
-structures are defined in <ruby.h>.
-
-To convert C numbers to Ruby value, use these macros.
-
- INT2FIX() for integers within 31bits.
- INT2NUM() for arbitrary sized integer.
-
-INT2NUM() converts integers into Bignums, if it is out of FIXNUM
-range, but bit slower.
-
-1.5 Manipulate Ruby data
-
-As I already told, it is not recommended to modify object's internal
-structure. To manipulate objects, use functions supplied by Ruby
-interpreter. Useful functions are listed below (not all):
-
- String functions
-
- rb_str_new(char *ptr, int len)
-
- Creates a new Ruby string.
-
- rb_str_new2(char *ptr)
-
- Creates a new Ruby string from C string. This is equivalent to
- rb_str_new(ptr, strlen(ptr)).
-
- rb_str_cat(VALUE str, char *ptr, int len)
-
- Appends len bytes data from ptr to the Ruby string.
-
- Array functions
-
- rb_ary_new()
-
- Creates an array with no element.
-
- rb_ary_new2(int len)
-
- Creates an array with no element, with allocating internal buffer
- for len elements.
-
- rb_ary_new3(int n, ...)
-
- Creates an n-elements array from arguments.
-
- rb_ary_new4(int n, VALUE *elts)
-
- Creates an n-elements array from 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)
- rb_ary_entry(VALUE ary, int idx)
-
- Array operations. The first argument to each functions must be an
- array. They may dump core if other types given.
-
-2. Extend Ruby with C
-
-2.1 Add new features to Ruby
-
-You can add new features (classes, methods, etc.) to the Ruby
-interpreter. Ruby provides the API to define things below:
-
- * Classes, Modules
- * Methods, Singleton Methods
- * Constants
-
-2.1.1 Class/module definition
-
-To define class or module, use functions below:
-
- VALUE rb_define_class(char *name, VALUE super)
- VALUE rb_define_module(char *name)
-
-These functions return the newly created class or module. You may
-want to save this reference into the variable to use later.
-
-2.1.2 Method/singleton method definition
-
-To define methods or singleton methods, use functions below:
-
- void rb_define_method(VALUE klass, char *name,
- VALUE (*func)(), int argc)
-
- void rb_define_singleton_method(VALUE object, 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 calling sequence, not number of
-the arguments.
-
-If argc is -1, the function will be called like:
-
- 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 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're two more functions to define method. One is to define
-private method:
-
- void rb_define_private_method(VALUE klass, char *name,
- VALUE (*func)(), int argc)
-
-The other is to define module function, which is private AND singleton
-method 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 function
-
- void rb_define_module_function(VALUE module, char *name,
- VALUE (*func)(), int argc)
-
-Oh, in addition, function-like method, which is private method defined
-in Kernel module, can be defined using:
-
- void rb_define_global_function(char *name, VALUE (*func)(), int argc)
-
-
-2.1.3 Constant definition
-
-We have 2 functions to define constants:
-
- void rb_define_const(VALUE klass, char *name, VALUE val)
- void rb_define_global_const(char *name, VALUE val)
-
-The former is to define constant under specified class/module. The
-latter is to define 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 Program in String
-
-Easiest way to call Ruby's function from C program is to evaluate the
-string as Ruby program. This function will do the job.
-
- VALUE rb_eval_string(char *str)
-
-Evaluation is done under 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 symbols (which data type is ID). ID is the
-integer number to represent Ruby's identifiers such as variable names.
-It can be accessed from Ruby in the form like:
-
- :Identifier
-
-You can get the symbol value from string within C code, by using
-
- rb_intern(char *name)
-
-In addition, the symbols for one character operators (e.g +) is the
-code for that character.
-
-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 the method of the recv, which name is 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 worlds.
-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 constant that C can be accessed from C
-
-Following Ruby constants can be referred from C.
-
- Qtrue
- Qfalse
-
-Boolean values. Qfalse is false in the 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 two worlds, using shared global
-variables. To define them, you can use functions listed below:
-
- void rb_define_variable(char *name, VALUE *var)
-
-This function defines the variable which is shared by the both world.
-The value of the global variable pointed by `var', can be accessed
-through Ruby's global variable named `name'.
-
-You can define read-only (from Ruby, of course) variable by the
-function below.
-
- void rb_define_readonly_variable(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(char *name, VALUE *var,
- VALUE (*getter)(), VALUE (*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(char *name,
- VALUE (*getter)(), VALUE (*setter)())
-
-This function defines the Ruby global variable without 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 following:
-
- (*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 wrapping and objectify the C pointer as 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 class 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. 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, free, works like their counterpart of
-Data_Wrap_Struct(). The pointer to allocated structure will be
-assigned to sval, which should be the pointer to the type specified.
-
-To retrieve the C pointer from the Data object, use the macro
-Data_Get_Struct().
-
- Data_Get_Struct(obj, type, sval)
-
-The pointer to the structure will be assigned to the variable sval.
-
-See example below for detail.
-
-4. Example - Creating dbm extension
-
-OK, here's the example to make extension library. This is the
-extension to access dbm. The full source is included in 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) create MANIFEST file
-
- % cd ext/dbm
- % touch MANIFEST
-
-There should be MANIFEST file in the directory for the extension
-library. Make empty file now.
-
-(3) design the library
-
-You need to design the library features, before making it.
-
-(4) 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 plural source
-files, avoid choosing ``LIBRARY.c'' for a file name. It may conflict
-with 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);
- :
-
-}
---
-
-The dbm extension wrap dbm struct in C world 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 dbmdata structure into Ruby object. We avoid wrapping
-DBM* directly, because we want to cache size information.
-
-To retrieve dbmdata structure from Ruby object, we define the macro below:
-
---
-#define GetDBM(obj, dbmp) {\
- Data_Get_Struct(obj, struct dbmdata, dbmp);\
- if (dbmp->di_dbm == 0) closed_dbm();\
-}
---
-
-This sort of complicated macro do the retrieving and close check for
-the DBM.
-
-There are three kind of way to receiving method arguments. First, the
-methods with fixed number of arguments receives 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, the methods with arbitrary number of arguments receives
-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, the method requires at least one
-argument, and at most receives two arguments.
-
-The methods with arbitrary number of arguments can receives 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 refers Ruby's objects, but
-not exported to the Ruby world. You need to protect them by
-
- void rb_global_variable(VALUE *var)
-
-(5) prepare extconf.rb
-
-If there exists the file named extconf.rb, it will be executed to
-generate Makefile. If not, compilation scheme try to generate
-Makefile anyway.
-
-The extconf.rb is the file to check compilation condition etc. You
-need to put
-
- require 'mkmf'
-
-at the top of the file. You can use the functions below to check the
-condition.
-
- have_library(lib, func): check whether library containing function exists.
- have_func(func): check whether function exists
- have_header(header): check whether header file exists
- create_makefile(target): generate Makefile
-
-The value of variables below will affect Makefile.
-
- $CFLAGS: included in CFLAGS make variable (such as -I)
- $LDFLAGS: included in LDFLAGS make variable (such as -L)
-
-If compilation condition is not fulfilled, you do not call
-``create_makefile''. Makefile will not generated, compilation will
-not be done.
-
-(6) prepare depend (optional)
-
-If the file named depend exists, Makefile will include that file to
-check dependency. You can make this file by invoking
-
- % gcc -MM *.c > depend
-
-It's no harm. Prepare it.
-
-(7) put file names into MANIFEST (optional)
-
- % find * -type f -print > MANIFEST
- % vi MANIFEST
-
-Append file names into MANIFEST. The compilation scheme requires
-MANIFEST only to be exist. But, you'd better take this step to
-distinguish required files.
-
-(8) generate Makefile
-
-Try generate Makefile by:
-
- ruby extconf.rb
-
-You don't need this step, if you put extension library under ext
-directory of the ruby source tree. In that case, compilation of the
-interpreter will do this step for you.
-
-(9) make
-
-Type
-
- make
-
-to compile your extension. You don't need this step neither, if you
-put extension library under ext directory of the ruby source tree.
-
-(9) debug
-
-You may need to rb_debug the extension. The extensions can be linked
-statically by adding directory name in the ext/Setup file, so that you
-can inspect the extension with the debugger.
-
-(10) done, now you have the extension library
-
-You can do anything you want with your library. The author of Ruby
-will not claim any restriction about your code depending Ruby API.
-Feel free to use, modify, distribute or sell your program.

-Appendix B. Ruby extension API reference
-
-** Types
-
- VALUE
-
-The type for 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)

-
-const: false object
-
-** C pointer wrapping
-
- Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval)
-
-Wrap C pointer into Ruby object. If object has references to other
-Ruby object, they should be marked by using mark function during 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.

-
-** Defining Global Variables
-
- void rb_define_variable(char *name, VALUE *var)

- VALUE (*getter)(), VALUE (*setter)())
-
-Defines a virtual variable, whose behavior is defined by pair of C
-functions. The getter function is called when the variable is

-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(char *name, VALUE *var,
- VALUE (*getter)(), VALUE (*setter)())

-the arguments are assigned to corresponding variable, packed in
-array.
-
-** Invoking Ruby method
-
- VALUE rb_funcall(VALUE recv, ID mid, int narg, ...)

-Raises fatal error, terminates the interpreter. No exception handling
-will be done for fatal error, but ensure blocks will be executed.
-
- void rb_bug(char *fmt, ...)
-
-Terminates the interpreter immediately. This function should be
-called under the situation caused by the bug in the interpreter. No

+# 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 (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, Mac OS X, BeOS, etc.) cf.
+ http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms
+
+
+## How to get Ruby
+
+For a complete list of ways to install Ruby, including using third-party tools
+like rvm, see:
+
+http://www.ruby-lang.org/en/downloads/
+
+The Ruby distribution files can be found on the following FTP site:
+
+ftp://ftp.ruby-lang.org/pub/ruby/
+
+The trunk of the Ruby source tree can be checked out with the following
+command:
+
+ $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
+
+Or if you are using git then use the following command:
+
+ $ git clone git://github.com/ruby/ruby.git
+
+There are some other branches under development. Try the following command
+to see the list of branches:
+
+ $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
+
+Or if you are using git then use the following command:
+
+ $ git ls-remote git://github.com/ruby/ruby.git
+
+## 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
+
+in the mail body (not subject) to the address
+<mailto:ruby-talk-request@ruby-lang.org>.
+
+## How to compile and install
+
+This is what you need to do to compile and install Ruby:
+
+1. If you want to use Microsoft Visual C++ to compile ruby, read
+ win32/README.win32 instead of this document.
+
+2. If `./configure` does not exist or is older than configure.in, run
+ `autoconf` to (re)generate configure.
+
+3. Run `./configure`, which will generate `config.h` and `Makefile`.
+
+ Some C compiler flags may be added by default depending on your
+ environment. Specify `optflags=..` and `warnflags=..` as necessary to
+ override them.
+
+4. Edit `defines.h` if you need. Usually this step will not be needed.
+
+5. 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 do not allow dynamic loading), remove comment mark
+ from the line "`#option nodynamic`" in `ext/Setup`.
+
+ Usually this step will not be needed.
+
+6. Run `make`.
+
+7. Optionally, run '`make check`' to check whether the compiled Ruby
+ interpreter works well. If you see the message "`check succeeded`", your
+ ruby works as it should (hopefully).
+
+8. Run '`make install`'
+
+ This command will create following directories and install files onto
+ them.
+
+ * `${DESTDIR}${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`
+
+
+ If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
+ `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
+
+ **NOTE**: teeny of the API version may be different from one of Ruby's
+ program version
+
+ 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.
+
+Some extension libraries may not get compiled because of lack of necessary
+external libraries and/or headers, then you will need to run '`make distclean-ext`'
+to remove old configuration after installing them in such case.
+
+## Copying
+
+See the file `COPYING`.
+
+## Feedback
+
+Questions about the Ruby language can be asked on the Ruby-Talk mailing list
+(http://www.ruby-lang.org/en/community/mailing-lists) or on websites like
+(http://stackoverflow.com).
+
+Bug reports should be filed at http://bugs.ruby-lang.org. Read [HowToReport] for more information.

+ * must return a number, and there must be two indices i and j
+ * (0 <= i <= j <= ary.size) so that:
+ *
+ * - the block returns a positive number for ary[k] if 0 <= k < i,
+ * - the block returns zero for ary[k] if i <= k < j, and
+ * - the block returns a negative number for ary[k] if
+ * j <= k < ary.size.

+/*
+ * Arrays are ordered, integer-indexed collections of any object.
+ *
+ * Array indexing starts at 0, as in C or Java. A negative index is assumed
+ * to be relative to the end of the array---that is, an index of -1 indicates
+ * the last element of the array, -2 is the next to last element in the
+ * array, and so on.
+ *
+ * == Creating Arrays
+ *
+ * A new array can be created by using the literal constructor
+ * <code>[]</code>. Arrays can contain different types of objects. For
+ * example, the array below contains an Integer, a String and a Float:
+ *
+ * ary = [1, "two", 3.0] #=> [1, "two", 3.0]
+ *
+ * An array can also be created by explicitly calling Array.new with zero, one
+ * (the initial size of the Array) or two arguments (the initial size and a
+ * default object).
+ *
+ * ary = Array.new #=> []
+ * Array.new(3) #=> [nil, nil, nil]
+ * Array.new(3, true) #=> [true, true, true]
+ *
+ * Note that the second argument populates the array with references to the
+ * same object. Therefore, it is only recommended in cases when you need to
+ * instantiate arrays with natively immutable objects such as Symbols,
+ * numbers, true or false.
+ *
+ * To create an array with separate objects a block can be passed instead.
+ * This method is safe to use with mutable objects such as hashes, strings or
+ * other arrays:
+ *
+ * Array.new(4) { Hash.new } #=> [{}, {}, {}, {}]
+ * Array.new(4) {|i| i.to_s } #=> ["0", "1", "2", "3"]
+ *
+ * This is also a quick way to build up multi-dimensional arrays:
+ *
+ * empty_table = Array.new(3) { Array.new(3) }
+ * #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ * An array can also be created by using the Array() method, provided by
+ * Kernel, which tries to call #to_ary, then #to_a on its argument.
+ *
+ * Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
+ *
+ * == 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]
+ *

+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 :-).
