-## Command line options
+## 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:
 
-* A new `performance` warning category was introduced.
-  They are not displayed by default even in verbose mode.
-  Turn them on with `-W:performance` or `Warning[:performance] = true`. [[Feature #19538]]
+    1. `foo`
+    2. `bar`
+    3. `a`
+    4. `b`
+    5. `[]=` called on the result of `foo`
+    6. `baz=` called on the result of `bar`
 
-* A new `RUBY_CRASH_REPORT` environment variable was introduced to allow
-  redirecting Ruby crash reports to a file or sub command. See the `BUG REPORT ENVIRONMENT`
-  section of the ruby manpage for further details. [[Feature #19790]]
+    [[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]]

-      The class use equality semantic to lookup keys like a regular hash,
-      but it doesn't hold strong references on the keys. [[Feature #18498]]
+    *   "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.

+
+* Kernel
 
-* Process
 
-    * New Process.warmup method that notify the Ruby virtual machine that the boot sequence is finished,
-      and that now is a good time to optimize the application. This is useful
-      for long-running applications. The actual optimizations performed are entirely
-      implementation-specific and may change in the future without notice. [[Feature #18885]]
+    *   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]]
 
-* Process::Status
+* Marshal
 
-    * Process::Status#& and Process::Status#>> are deprecated. [[Bug #19868]]
+    *   Marshal.load now accepts a `freeze: true` option.
+        All returned objects are frozen except for `Class` and

+        UnboundMethod#public?, UnboundMethod#private?,
+        UnboundMethod#protected? have been added. [[Feature #11689]]
 
-    * The cache-based optimization now supports lookarounds and atomic groupings. That is, match
-      for Regexp containing these extensions can now also be performed in linear time to the length
-      of the input string. However, these cannot contain captures and cannot be nested. [[Feature #19725]]
+* 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]]

+        and Emoji version to 13.0 [[Feature #18029]]
 
-* Thread::Queue
+    *   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::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 with a string argument became stricter. [[Bug #19293]]
+    *   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('2023-12-20')
-        #  no time information (ArgumentError)
+        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 supports `rescue` event. When the raised exception was rescued,
-      the TracePoint will fire the hook. `rescue` event only supports Ruby-level
-      `rescue`. [[Feature #19572]]
+    *   TracePoint.allow_reentry is added to allow reenter while TracePoint
+        callback.
+        [[Feature #15912]]
 
-## Stdlib updates

-### Prism
-
-* Introduced [the Prism parser](https://github.com/ruby/prism) as a default gem
-    * Prism is a portable, error tolerant, and maintainable recursive descent parser for the Ruby language
-* Prism is production ready and actively maintained, you can use it in place of Ripper
-    * There is [extensive documentation](https://ruby.github.io/prism/) on how to use Prism
-    * Prism is both a C library that will be used internally by CRuby and a Ruby gem that can be used by any tooling which needs to parse Ruby code
-    * Notable methods in the Prism API are:
-        * `Prism.parse(source)` which returns the AST as part of a parse result object
-        * `Prism.parse_comments(source)` which returns the comments
-        * `Prism.parse_success?(source)` which returns true if there are no errors
-* You can make pull requests or issues directly on [the Prism repository](https://github.com/ruby/prism) if you are interested in contributing
-* You can now use `ruby --parser=prism` or `RUBYOPT="--parser=prism"` to experiment with the Prism compiler. Please note that this flag is for debugging only.
+    *   $LOAD_PATH.resolve_feature_path does not raise. [[Feature #16043]]

+        [[Feature #17370]]
 
-* When given a non-lambda, non-literal block, Kernel#lambda with now raises
-  ArgumentError instead of returning it unmodified. These usages have been
-  issuing warnings under the `Warning[:deprecated]` category since Ruby 3.0.0.
-  [[Feature #19777]]
+    *   Introduce non-blocking `Timeout.timeout` using `timeout_after` hook.
+        [[Feature #17470]]
 
-* The `RUBY_GC_HEAP_INIT_SLOTS` environment variable has been deprecated and
-  removed. Environment variables `RUBY_GC_HEAP_%d_INIT_SLOTS` should be
-  used instead.  [[Feature #19785]]
+    *   Introduce new scheduler hooks `io_read` and `io_write` along with a
+        low level `IO::Buffer` for zero-copy read/write. [[Feature #18020]]
 
-* `it` calls without arguments in a block with no ordinary parameters are
-  deprecated. `it` will be a reference to the first block parameter in Ruby 3.4.
-  [[Feature #18980]]
+    *   IO hooks `io_wait`, `io_read`, `io_write`, receive the original IO object
+        where possible. [[Bug #18003]]
 
-* Error message for NoMethodError have changed to not use the target object's `#inspect`
-  for efficiency, and says "instance of ClassName" instead. [[Feature #18285]]
+    *   Make `Monitor` fiber-safe. [[Bug #17827]]
 
-    ```ruby
-    ([1] * 100).nonexisting
-    # undefined method `nonexisting' for an instance of Array (NoMethodError)
-    ```
+    *   Replace copy coroutine with pthread implementation. [[Feature #18015]]
+
+* Refinement
 
-* Now anonymous parameters forwarding is disallowed inside a block
-  that uses anonymous parameters.  [[Feature #19370]]
+    *   New class which represents a module created by Module#refine.
+        `include` and `prepend` are deprecated, and `import_methods` is added
+        instead. [[Bug #17429]]

+  See [[Feature #18176]] in detail.
+
+* Random::Formatter is moved to random/formatter.rb, so that you can

+  [[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
 
-* `racc` is promoted to bundled gems.
-    * You need to add `racc` to your `Gemfile` if you use `racc` under bundler environment.
-* `ext/readline` is retired
-    * We have `reline` that is pure Ruby implementation compatible with `ext/readline` API.
-      We rely on `reline` in the future. If you need to use `ext/readline`, you can install
-      `ext/readline` via rubygems.org with `gem install readline-ext`.
-    * We no longer need to install libraries like `libreadline` or `libedit`.
+* `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
 
-* `rb_postponed_job` updates
-  * New APIs and deprecated APIs (see comments for details)
-    * added: `rb_postponed_job_preregister()`
-    * added: `rb_postponed_job_trigger()`
-    * deprecated: `rb_postponed_job_register()` (and semantic change. see below)
-    * deprecated: `rb_postponed_job_register_one()`
-  * The postponed job APIs have been changed to address some rare crashes.
-    To solve the issue, we introduced new two APIs and deprecated current APIs.
-    The semantics of these functions have also changed slightly; `rb_postponed_job_register`
-    now behaves like the `once` variant in that multiple calls with the same
-    `func` might be coalesced into a single execution of the `func`
-    [[Feature #20057]]
-
-* Some updates for internal thread event hook APIs
-  * `rb_internal_thread_event_data_t` with a target Ruby thread (VALUE)
-    and callback functions (`rb_internal_thread_event_callback`) receive it.
-    https://github.com/ruby/ruby/pull/8885
-  * The following functions are introduced to manipulate Ruby thread local data
-    from internal thread event hook APIs (they are introduced since Ruby 3.2).
-    https://github.com/ruby/ruby/pull/8936
-    * `rb_internal_thread_specific_key_create()`
-    * `rb_internal_thread_specific_get()`
-    * `rb_internal_thread_specific_set()`
-
-* `rb_profile_thread_frames()` is introduced to get a frames from
-  a specific thread.
-  [[Feature #10602]]
-
-* `rb_data_define()` is introduced to define `Data`. [[Feature #19757]]
-
-* `rb_ext_resolve_symbol()` is introduced to search a function from
-  extension libraries. [[Feature #20005]]
-
-* IO related updates:
-  * The details of `rb_io_t` will be hidden and deprecated attributes
-    are added for each members. [[Feature #19057]]
-  * `rb_io_path(VALUE io)` is introduced to get a path of `io`.
-  * `rb_io_closed_p(VALUE io)` to get opening or closing of `io`.
-  * `rb_io_mode(VALUE io)` to get the mode of `io`.
-  * `rb_io_open_descriptor()` is introduced to make an IO object from a file
-    descriptor.
+* Documented. [[GH-4815]]
+
+* `rb_gc_force_recycle` is deprecated and has been changed to a no-op.
+  [[Feature #18290]]
 
 ## Implementation improvements
 
-### Parser
-
-* Replace Bison with [Lrama LALR parser generator](https://github.com/ruby/lrama).
-  No need to install Bison to build Ruby from source code anymore.
-  We will no longer suffer bison compatibility issues and we can use new features by just implementing it to Lrama. [[Feature #19637]]
-  * See [The future vision of Ruby Parser](https://rubykaigi.org/2023/presentations/spikeolaf.html) for detail.
-  * Lrama internal parser is a LR parser generated by Racc for maintainability.
-  * Parameterizing Rules `(?, *, +)` are supported, it will be used in Ruby parse.y.
-
-### GC / Memory management
-
-* Major performance improvements over Ruby 3.2
-    * Young objects referenced by old objects are no longer immediately
-      promoted to the old generation. This significantly reduces the frequency of
-      major GC collections. [[Feature #19678]]
-    * A new `REMEMBERED_WB_UNPROTECTED_OBJECTS_LIMIT_RATIO` tuning variable was
-      introduced to control the number of unprotected objects cause a major GC
-      collection to trigger. The default is set to `0.01` (1%). This significantly
-      reduces the frequency of major GC collection. [[Feature #19571]]
-    * Write Barriers were implemented for many core types that were missing them,
-      notably `Time`, `Enumerator`, `MatchData`, `Method`, `File::Stat`, `BigDecimal`
-      and several others. This significantly reduces minor GC collection time and major
-      GC collection frequency.
-    * Most core classes are now using Variable Width Allocation, notably `Hash`, `Time`,
-      `Thread::Backtrace`, `Thread::Backtrace::Location`, `File::Stat`, `Method`.
-      This makes these classes faster to allocate and free, use less memory and reduce
-      heap fragmentation.
-* `defined?(@ivar)` is optimized with Object Shapes.
-
-### YJIT
-
-* Major performance improvements over Ruby 3.2
-  * Support for splat and rest arguments has been improved.
-  * Registers are allocated for stack operations of the virtual machine.
-  * More calls with optional arguments are compiled. Exception handlers are also compiled.
-  * Unsupported call types and megamorphic call sites no longer exit to the interpreter.
-  * Basic methods like Rails `#blank?` and
-    [specialized `#present?`](https://github.com/rails/rails/pull/49909) are inlined.
-  * `Integer#*`, `Integer#!=`, `String#!=`, `String#getbyte`,
-    `Kernel#block_given?`, `Kernel#is_a?`, `Kernel#instance_of?`, and `Module#===`
-    are specially optimized.
-  * Compilation speed is now slightly faster than Ruby 3.2.
-  * Now more than 3x faster than the interpreter on Optcarrot!
-* Significantly improved memory usage over Ruby 3.2
-    * Metadata for compiled code uses a lot less memory.
-    * `--yjit-call-threshold` is automatically raised from 30 to 120
-      when the application has more than 40,000 ISEQs.
-    * `--yjit-cold-threshold` is added to skip compiling cold ISEQs.
-    * More compact code is generated on Arm64.
-* Code GC is now disabled by default
-  * `--yjit-exec-mem-size` is treated as a hard limit where compilation of new code stops.
-  * No sudden drops in performance due to code GC.
-    Better copy-on-write behavior on servers reforking with
-    [Pitchfork](https://github.com/shopify/pitchfork).
-  * You can still enable code GC if desired with `--yjit-code-gc`
-* Add `RubyVM::YJIT.enable` that can enable YJIT at run-time
-  * You can start YJIT without modifying command-line arguments or environment variables.
-    Rails 7.2 will [enable YJIT by default](https://github.com/rails/rails/pull/49947)
-    using this method.
-  * This can also be used to enable YJIT only once your application is
-    done booting. `--yjit-disable` can be used if you want to use other
-    YJIT options while disabling YJIT at boot.
-* More YJIT stats are available by default
-  * `yjit_alloc_size` and several more metadata-related stats are now available by default.
-  * `ratio_in_yjit` stat produced by `--yjit-stats` is now available in release builds,
-    a special stats or dev build is no longer required to access most stats.
-* Add more profiling capabilities
-  * `--yjit-perf` is added to facilitate profiling with Linux perf.
-  * `--yjit-trace-exits` now supports sampling with `--yjit-trace-exits-sample-rate=N`
-* More thorough testing and multiple bug fixes
-* `--yjit-stats=quiet` is added to avoid printing stats on exit.
+* 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
 
-* MJIT is removed.
-    * `--disable-jit-support` is removed. Consider using `--disable-yjit --disable-rjit` instead.
-
-### RJIT
-
-* Introduced a pure-Ruby JIT compiler RJIT.
-    * RJIT supports only x86\_64 architecture on Unix platforms.
-    * Unlike MJIT, it doesn't require a C compiler at runtime.
-* RJIT exists only for experimental purposes.
-    * You should keep using YJIT in production.
-
-### M:N Thread scheduler
-
-* M:N Thread scheduler is introduced. [[Feature #19842]]
-    * Background: Ruby 1.8 and before, M:1 thread scheduler (M Ruby threads
-      with 1 native thread. Called as User level threads or Green threads)
-      is used. Ruby 1.9 and later, 1:1 thread scheduler (1 Ruby thread with
-      1 native thread). M:1 threads takes lower resources compare with 1:1
-      threads because it needs only 1 native threads. However it is difficult
-      to support context switching for all of blocking operation so 1:1
-      threads are employed from Ruby 1.9. M:N thread scheduler uses N native
-      threads for M Ruby threads (N is small number in general). It doesn't
-      need same number of native threads as Ruby threads (similar to the M:1
-      thread scheduler). Also our M:N threads supports blocking operations
-      well same as 1:1 threads. See the ticket for more details.
-      Our M:N thread scheduler refers on the goroutine scheduler in the
-      Go language.
-    * In a ractor, only 1 thread can run in a same time because of
-      implementation. Therefore, applications that use only one Ractor
-      (most applications) M:N thread scheduler works as M:1 thread scheduler
-      with further extension from Ruby 1.8.
-    * M:N thread scheduler can introduce incompatibility for C-extensions,
-      so it is disabled by default on the main Ractors.
-      `RUBY_MN_THREADS=1` environment variable will enable it.
-      On non-main Ractors, M:N thread scheduler is enabled (and can not
-      disable it now).
-    * `N` (the number of native threads) can be specified with `RUBY_MAX_CPU`
-      environment variable. The default is 8.
-      Note that more than `N` native threads are used to support many kind of
-      blocking operations.

+* 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/master/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/master/CHANGELOG.md) for more information.
+
+### TypeProf
+
+* [Experimental IDE support](https://github.com/ruby/typeprof/blob/master/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`.

+## Requirements to build from repository
+
+1. GNU or BSD make
+2. C99 compiler
+3. autoconf 2.67 or higher
+4. automake 1.15 or higher
+5. bison 2.3 or higher
+6. Ruby 2.2 or higher
+
+When building from a released version, only a C99 compiler and GNU or BSD make
+is required.
+
+## How to compile and install
+
+1.  If you want to use Microsoft Visual C++ to compile Ruby, read
+    [win32/README.win32](rdoc-ref:win32/README.win32) instead of this document.
+
+2.  Run `./autogen.sh` to generate configure, when you build the source checked
+    out from the Git repository.
+
+3.  Run `./configure`, which will generate `config.h` and `Makefile`.
 
-in the mail subject (not body) to the address [ruby-talk-request@ml.ruby-lang.org].
+    Some C compiler flags may be added by default depending on your
+    environment. Specify `optflags=..` and `warnflags=..` as necessary to
+    override them.
 
-[ruby-talk-request@ml.ruby-lang.org]: mailto:ruby-talk-request@ml.ruby-lang.org?subject=join
+4.  Edit `include/ruby/defines.h` if you need. Usually this step will not be needed.
+
+5.  Optional: Remove comment mark(`#`) before the module names from `ext/Setup`.
+
+    This step is only necessary if you want to link modules statically.
+
+    If you don't want to compile dynamic extensions (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`.
+
+    * On Mac, set RUBY\_CODESIGN environment variable with a signing identity.
+      It uses the identity to sign `ruby` binary. See also codesign(1).
+
+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 the following directories and install files into
+    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.

- *      Array.new               # => []

- *      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.
- *
- *  - ARGF#to_a
- *  - Array#to_a
- *  - Enumerable#to_a

+ *  - An {array literal}[doc/syntax/literals_rdoc.html#label-Array+Literals].
+ *
+ *  You can convert certain objects to Arrays with:
+ *
+ *  - \Method {Array}[Kernel.html#method-i-Array].
+ *
+ *  An \Array 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 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"]]

+ *  Document-class: Fiber::SchedulerInterface
+ *
+ *  This is not an existing class, but documentation of the interface that Scheduler
+ *  object should comply to in order to be used as argument to Fiber.scheduler and handle non-blocking
+ *  fibers. See also the "Non-blocking fibers" section in Fiber class docs for explanations
+ *  of some concepts.
+ *
+ *  Scheduler's behavior and usage are expected to be as follows:
+ *
+ *  * When the execution in the non-blocking Fiber reaches some blocking operation (like
+ *    sleep, wait for a process, or a non-ready I/O), it calls some of the scheduler's
+ *    hook methods, listed below.
+ *  * Scheduler somehow registers what the current fiber is waiting on, and yields control
+ *    to other fibers with Fiber.yield (so the fiber would be suspended while expecting its
+ *    wait to end, and other fibers in the same thread can perform)
+ *  * At the end of the current thread execution, the scheduler's method #close is called
+ *  * The scheduler runs into a wait loop, checking all the blocked fibers (which it has
+ *    registered on hook calls) and resuming them when the awaited resource is ready
+ *    (e.g. I/O ready or sleep time elapsed).
+ *
+ *  A typical implementation would probably rely for this closing loop on a gem like
+ *  EventMachine[https://github.com/eventmachine/eventmachine] or
+ *  Async[https://github.com/socketry/async].
+ *
+ *  This way concurrent execution will be achieved transparently for every
+ *  individual Fiber's code.
+ *
+ *  Hook methods are:
+ *
+ *  * #io_wait, #io_read, and #io_write
+ *  * #process_wait
+ *  * #kernel_sleep
+ *  * #timeout_after
+ *  * #address_resolve
+ *  * #block and #unblock
+ *  * (the list is expanded as Ruby developers make more methods having non-blocking calls)
+ *
+ *  When not specified otherwise, the hook implementations are mandatory: if they are not
+ *  implemented, the methods trying to call hook will fail. To provide backward compatibility,
+ *  in the future hooks will be optional (if they are not implemented, due to the scheduler
+ *  being created for the older Ruby version, the code which needs this hook will not fail,
+ *  and will just behave in a blocking fashion).
+ *
+ *  It is also strongly recommended that the scheduler implements the #fiber method, which is
+ *  delegated to by Fiber.schedule.
+ *
+ *  Sample _toy_ implementation of the scheduler can be found in Ruby's code, in

-# An object of class \Dir represents a directory in the underlying file system.
+# 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.
 #
-# It consists mainly of:
-#
-# - A string _path_, given when the object is created,
-#   that specifies a directory in the underlying file system;
-#   method #path returns the path.
-# - A collection of string <i>entry names</i>,
-#   each of which is the name of a directory or file in the underlying file system;
-#   the entry names may be retrieved
-#   in an {array-like fashion}[rdoc-ref:Dir@Dir+As+Array-Like]
-#   or in a {stream-like fashion}[rdoc-ref:Dir@Dir+As+Stream-Like].
-#
-# == About the Examples
-#
-# Some examples on this page use this simple file tree:
-#
-#   example/
-#   ├── config.h
-#   ├── lib/
-#   │   ├── song/
-#   │   │   └── karaoke.rb
-#   │   └── song.rb
-#   └── main.rb
-#
-# Others use the file tree for the
-# {Ruby project itself}[https://github.com/ruby/ruby].
-#
-# == \Dir As \Array-Like
-#
-# A \Dir object is in some ways array-like:
-#
-# - It has instance methods #children, #each, and #each_child.
-# - It includes {module Enumerable}[rdoc-ref:Enumerable@What-27s+Here].
-#
-# == \Dir As Stream-Like
-#
-# A \Dir object is in some ways stream-like.
-#
-# The stream is initially open for reading,
-# but may be closed manually (using method #close),
-# and will be closed on block exit if created by Dir.open called with a block.
-# The closed stream may not be further manipulated,
-# and may not be reopened.
-#
-# The stream has a _position_, which is the index of an entry in the directory:
-#
-# - The initial position is zero (before the first entry).
-# - \Method #tell (aliased as #pos) returns the position.
-# - \Method #pos= sets the position (but ignores a value outside the stream),
-#   and returns the position.
-# - \Method #seek is like #pos=, but returns +self+ (convenient for chaining).
-# - \Method #read, if not at end-of-stream, reads the next entry and increments
-#   the position;
-#   if at end-of-stream, does not increment the position.
-# - \Method #rewind sets the position to zero.
-#
-# Examples (using the {simple file tree}[rdoc-ref:Dir@About+the+Examples]):
-#
-#   dir = Dir.new('example') # => #<Dir:example>
-#   dir.pos                  # => 0
-#
-#   dir.read # => "."
-#   dir.read # => ".."
-#   dir.read # => "config.h"
-#   dir.read # => "lib"
-#   dir.read # => "main.rb"
-#   dir.pos  # => 5
-#   dir.read # => nil
-#   dir.pos  # => 5
-#
-#   dir.rewind # => #<Dir:example>
-#   dir.pos    # => 0
-#
-#   dir.pos = 3 # => 3
-#   dir.pos     # => 3
-#
-#   dir.seek(4) # => #<Dir:example>
-#   dir.pos     # => 4
-#
-#   dir.close # => nil
-#   dir.read  # Raises IOError.
+# 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],
+# - Inherits from {class Object}[Object.html#class-Object-label-What-27s+Here].
+# - Includes {module Enumerable}[Enumerable.html#module-Enumerable-label-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}[#class-Dir-label-Reading]
+# - {Setting}[#class-Dir-label-Setting]
+# - {Querying}[#class-Dir-label-Querying]
+# - {Iterating}[#class-Dir-label-Iterating]
+# - {Other}[#class-Dir-label-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.
+# - #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.
+# - ::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.

-  # Each pattern string is expanded
-  # according to certain metacharacters;
-  # examples below use the {Ruby file tree}[rdoc-ref:Dir@About+the+Examples]:
-  #
-  # - <tt>'*'</tt>: Matches any substring in an entry name,
-  #   similar in meaning to regexp <tt>/.*/mx</tt>;
-  #   may be restricted by other values in the pattern strings:
-  #
-  #   - <tt>'*'</tt> matches all entry names:
-  #
-  #       Dir.glob('*').take(3)  # => ["BSDL", "CONTRIBUTING.md", "COPYING"]
-  #
-  #   - <tt>'c*'</tt> matches entry names beginning with <tt>'c'</tt>:
-  #
-  #       Dir.glob('c*').take(3) # => ["CONTRIBUTING.md", "COPYING", "COPYING.ja"]
-  #
-  #   - <tt>'*c'</tt> matches entry names ending with <tt>'c'</tt>:
-  #
-  #       Dir.glob('*c').take(3) # => ["addr2line.c", "array.c", "ast.c"]
-  #
-  #   - <tt>'\*c\*'</tt> matches entry names that contain <tt>'c'</tt>,
-  #     even at the beginning or end:
-  #
-  #       Dir.glob('*c*').take(3) # => ["CONTRIBUTING.md", "COPYING", "COPYING.ja"]
-  #
-  #   Does not match Unix-like hidden entry names ("dot files").
-  #   To include those in the matched entry names,
-  #   use flag IO::FNM_DOTMATCH or something like <tt>'{*,.*}'</tt>.
-  #
-  #  - <tt>'**'</tt>: Matches entry names recursively
-  #    if followed by  the slash character <tt>'/'</tt>:
-  #
-  #      Dir.glob('**/').take(3) # => ["basictest/", "benchmark/", "benchmark/gc/"]
-  #
-  #    If the string pattern contains other characters
-  #    or is not followed by a slash character,
-  #    it is equivalent to <tt>'*'</tt>.
-  #
-  # - <tt>'?'</tt> Matches any single character;
-  #   similar in meaning to regexp <tt>/./</tt>:
-  #
-  #     Dir.glob('io.?') # => ["io.c"]
-  #
-  # - <tt>'[_set_]'</tt>: Matches any one character in the string _set_;
-  #   behaves like a {Regexp character class}[rdoc-ref:Regexp@Character+Classes],
-  #   including set negation (<tt>'[^a-z]'</tt>):
-  #
-  #     Dir.glob('*.[a-z][a-z]').take(3)
-  #     # => ["CONTRIBUTING.md", "COPYING.ja", "KNOWNBUGS.rb"]
-  #
-  # - <tt>'{_abc_,_xyz_}'</tt>:
-  #   Matches either string _abc_ or string _xyz_;
-  #   behaves like {Regexp alternation}[rdoc-ref:Regexp@Alternation]:
-  #
-  #     Dir.glob('{LEGAL,BSDL}') # => ["LEGAL", "BSDL"]
-  #
-  #   More than two alternatives may be given.
-  #
-  # - <tt>\\</tt>: Escapes the following metacharacter.
-  #
-  #   Note that on Windows, the backslash character may not be used
-  #   in a string pattern:
-  #   <tt>Dir['c:\\foo*']</tt> will not work, use <tt>Dir['c:/foo*']</tt> instead.

+
+	* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,
+	  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.

+	  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

+	  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/*: full update Ruby/Tk to support Ruby(1.9|1.8) and Tc/Tk8.5.
+
+	* 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/tk.rb: remove Thread.critical access if Ruby1.9
+
+	* ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably)
+
+	* 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.

+
+	* ext/syck/gram.c: headless documents of any kind allowed.
+
+	* ext/syck/node.c: new syck_replace_str methods and syck_empty_*

+
+	  == 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

+	    '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,

+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().

+	  (null or non-null) and rb_thread_t::trace_running is removed.
+	  After that, `rb_tp_t' is not needed to check tracing or not
+	  (A running thread knows tracing or not). This is why I remove
+	  tp_attr_check_active() and make new function get_trace_arg().
+
+	  And this modification disable to work the following code:
+	    TracePoint.trace{|tp|
+	      Thread.new{p tp.event} # access `tp' from other threads.

+
+	* 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

+
+	* fix the behavior when a module is included into a refinement.

+	  module inclusion to refinements.
+
+	* include/ruby/ruby.h (RMODULE_INCLUDED_INTO_REFINEMENT): new flag
+	  to represent that a module (iclass) is included into a refinement.
+
+	* class.c (include_modules_at): set RMODULE_INCLUDED_INTO_REFINEMENT

+
+	* eval.c (rb_mod_refine): set the superclass of a refinement to the
+	  refined class for super.
+
+	* 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,
+	  where <Module> is an iclass for Module, so RefinedClass is
+	  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
+	  vm_search_normal_superclass(), the receiver might not be an
+	  instance of the module('s iclass).

+
+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_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.
+	  Receive `func' pointer as the first parameter.

+
+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 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

+	  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).

+
+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.
+
+	* vm_eval.c (vm_call0_body): catch up above changes.
+
+Mon Oct 15 03:51:46 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* benchmark/bm_vm1_attr_ivar(_set).rb: added (for method dispatch speed).

+
+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()
+	  and remove unused function parameter.

+	* thread.c (thread_create_core): no need to set RUBY_VM_VM.
+
+	* vm.c (mark_event_hooks): move definition to vm_trace.c.

+	* vm.c (ruby_vm_event_flags): add a global variable.

+	  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.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:

+
+	* 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

+
+	* 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 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.

+
+	* 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]

+
+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

+
+	  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.

+	* vm_insnhelper.c (vm_get_ev_const): Apply same change as

+	  This problem is caused by changing dfp (dynamic env pointer)
+	  from saved dfp.  Saved dfp is pointed env in VM stack.  However,
+	  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

+	  RubyVM::InstructionSequence, then use it instead of created one.
+
+	  For example, this method is useful to test iseq dumper/loader
+	  such as RubyVM::InstructionSequence#to_a and rb_iseq_load().
+
+	  Because this method is for such internal experimental usage,
+	  the interface is not matured. For example, this interface has
+	  no extensibility. Two or more translators can not run
+	  simultaneously.
+
+	  So that we don't guarantee future compatibility of this method.
+	  Basically, do not use this method.

+
+	* 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.

+	  [Feature #10600]
+
+	  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

+Sat Aug 22 08:23:32 2015  Koichi Sasada  <ko1@atdot.net>
+
+	* 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.

+
+	  rb_method_entry_t data belong to modules/classes.

+	    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.
+
+	* class.c (method_entry_i): ditto.
+
+	* class.c (rb_define_attr): rb_method_entry() does not takes

+	  on Solaris 10. [Bug #11265] [ruby-dev:49089]
+
+	* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
+	  because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,
+	  execv() in exec_with_sh() and proc_exec_cmd() are never called.
+	  To guarantee this, execv() is replaced by a macro to print
+	  out error message on Solaris 10.
+
+	* 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
+	  of ruby, it may be called by third-party extensions.

+
+	  Added (but disabled) code changes current behaviour. This fix promote

+	  "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.

-
-	* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,
-	  RB_RESERVED_FD_P): added.  This C API is to limit to access

-	  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

-	  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.

-	  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.

-	  Skip syslog tests that rely on LOG_PERROR unless it's defined
-
-	  Instead of checking looking at the platform to determine if the tests
-	  relying on LOG_PERROR should be run, look for the definition of the

-
-	  This specifically addresses failures on Solaris 9.
-
-	  Use LOG_PID instead of LOG_PERROR in Syslog.open test
-
-	  LOG_PERROR isn't a POSIX option for syslog, so it fails on platforms
-	  that don't define it.  Solaris 9 and 10 are examples of this.

-	  by automatic integral promotion to fit to the prototype of

-	* test/net/imap/test_imap.rb: "localhost" not guaranteed to
-	  resolve to "127.0.0.1".  On my machine it is "::1" instead.
-	  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.

-	* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):
-	  added.  Unlinked method entries are collected to
-	  vm->unlinked_method_entry_list.  On the GC timing, mark all method
-	  entries which are on all living threads.  Only non-marked method
-	  entries are collected.  This hack prevents releasing living method
-	  entry.
-	  [Performance Consideration] Since this Method Entry GC (MEGC)
-	  doesn't occur frequently, MEGC will not be a performance bottleneck.
-	  However, to traverse living method entries, every control frame push
-	  needs to clear cfp->me field.  This will be a performance issue
-	  (because pushing control frame is occurred frequently).

-	  Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
-	  not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g.
-	  :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).

-	  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/sample/demos-en/textpeer.rb: new widget demo.
-
-	* ext/tk/tcltklib.c: decrease SEGV troubles (probably)
-
-	* ext/tk/lib/tk.rb: remove Thread.critical access if Ruby1.9
-
-	* ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably)
-
-	* 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).

-	  convenient instance methods such as "new()", for creating a new
-	  copy, parameter taking "digest()" and "hexdigest()", for instant
-	  calculation.  These methods make digest instances work just like
-	  digest classes.
-
-	* ext/digest/sha2/lib/digest/sha2.rb:
-	  Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256,

-
-Sun Oct 15 01:03:08 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>

-
-	* ext/digest/lib/digest/hmac.rb: Completely redesign the somewhat

-
-	* ext/digest/digest.c: Improve RDoc documentation further more.

-
-	* ext/digest/digest.c (Init_digest, rb_digest_base_s_digest,

-	* ext/digest/digest.c (Init_digest): Digest::Base.new() does no
-	  longer take an initial string to feed.  This change allows
-	  subclasses to take hashing parameters.  A statement such as
-	  ``md = Digest::MD5.new(s)'' can be easily rewritten as
-	  ``md = Digest::MD5.new << s'' or
-	  ``md = Digest::MD5.new.update(s)''.

-
-Thu Oct 12 02:12:31 2006  Akinori MUSHA  <knu@iDaemons.org>
-
-	* ext/digest/digest.c (get_digest_base_metadata): Use an instance
-	  variable of a class object instead of a class variable for
-	  metadata.  This change is only crucial for ruby 1.8 because
-	  class variables are inherited to subclasses prior to 1.9, but

-
-Mon Dec 19 23:09:24 2005  Hirokazu Yamamoto  <ocean@m2.ccsnet.ne.jp>
-
-	* 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
-	  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 (syck_parser_load): ditto.

-
-	* ext/syck/rubyext.c (syck_scalar_value_set): "should set newly

-	  by this, should call syck_free_node instead of rb_syck_free_node.
-
-	* ext/syck/rubyext.c (syck_node_type_id_set): 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)

-Sat Dec 17 21:50:41 2005  Hirokazu Yamamoto  <ocean@m2.ccsnet.ne.jp>
-
-	* ext/syck/rubyext.c (syck_emitter_reset): should initialize
-	  emitter->bonus->oid. otherwise rb_gc_mark crashes.
-
-	* ext/syck/rubyext.c (syck_mark_parser): should mark anchor nodes
-	  because they hold ruby objects. (ie: rb_syck_bad_anchor_handler)

-
-	* win32/win32.c (rb_w32_select): fixed deadlock bug.
-	  because select(2) modifies its fd_set arguments, it must be
-	  restored sometimes.
-
-	* win32/win32.c (rb_w32_select): performance improvement when
-	 'always readable/writable handles' and sockets are passed.
-	  sockets should be polled every time.
-

-	  but still has performance problem because I loosely took 1 second
-	  for wait time. I'll fix it later. (The reason I drastically changed
-	  the code is that I wanted to implement the fileset management as
-	  single function, and I was worried that if pipe or console

-
-Sat Sep 17 11:24:16 2005  Hirokazu Yamamoto  <ocean@m2.ccsnet.ne.jp>
-
-	* win32/win32.c (rb_w32_select): select for socket didn't work.
-	  this caused deadlock in drb test. this happened because GetFileType
-	  for socket handle returns FILE_TYPE_PIPE. Of course, it's not a
-	  pipe. So socket handle didn't reach winsock's select function.
-
-	* win32/win32.c (rb_w32_select): read for pipe was still blocked
-	  even if writer handle was closed.
-
-	    r,w = IO.pipe
-
-	    Thread.new {
-	      sleep 3; puts "------- 1"

-	    until r.eof? # should break by w.close but didn't.
-	      puts r.gets

-
-	* win32/win32.c (rb_w32_select): temporary reverted console support
-	  but it'll be back soon.

-
-	* 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] 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

-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().

-	    - 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.

-
-	* 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
-	  an above change.

-
-	* fix the behavior when a module is included into a refinement.
-	  This change is a little tricky, so it might be better to prohibit
-	  module inclusion to refinements.
-
-	* include/ruby/ruby.h (RMODULE_INCLUDED_INTO_REFINEMENT): new flag
-	  to represent that a module (iclass) is included into a refinement.
-
-	* class.c (include_modules_at): set RMODULE_INCLUDED_INTO_REFINEMENT
-	  if klass is a refinement.
-
-	* eval.c (rb_mod_refine): set the superclass of a refinement to the
-	  refined class for super.
-
-	* 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,
-	  where <Module> is an iclass for Module, so RefinedClass is
-	  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
-	  vm_search_normal_superclass(), the receiver might not be an
-	  instance of the module('s iclass).

-Mon Dec 10 18:35:25 2012  Shugo Maeda  <shugo@ruby-lang.org>

-	  TESTS="json ruby/test_refinement.rb".

-
-	* vm_insnhelper.c (lep_svar_get, lep_svar_set, vm_getspecial): store
-	  flip-flop states in an array instead of a hash.
-
-	* iseq.c (set_relation): main iseq also can has local scope.

-
-	* 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

-
-	* class.c (rb_prepend_module): set an empty table to

-	  queue.  [Feature #6638]
-	  when array is shared (which happens after Array#shift), and

-	  then make rb_ary_push push directly into shared array.
-
-	* array.c (rb_ary_modify): steal shared array's container when
-	  ARY_SHARED_NUM == 1.  [Feature #6638]
-	  - Do not allocate new memory in rb_ary_modify when ARY_SHARED_NUM == 1
-	    and length almost same.
-	  - Store ARY_CAPA instead of RARRAY_LEN in ary_make_shared, to make
-	    it useful.

-
-Tue Oct 23 12:57:29 2012  Koichi Sasada  <ko1@atdot.net>
-
-	* 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.
-	  Receive `func' pointer as the first parameter.

-	      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.
-	  (3) Change default directory from './' to driver's directory.

-
-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.

-	  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.
-
-	* vm_eval.c (vm_call0_body): catch up above changes.
-
-Mon Oct 15 03:51:46 2012  Koichi Sasada  <ko1@atdot.net>
-
-	* benchmark/bm_vm1_attr_ivar(_set).rb: added (for method dispatch speed).
-
-	* benchmark/bm_vm1_float_simple.rb: added (for flonum/float).
-
-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_eval.c (vm_call0): ditto (it will be rewritten soon).

-	* 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()
-	  and remove unused function parameter.
-
-	* parse.y: fix to use renamed rb_suppress_tracing().
-
-	* thread.c (thread_create_core): no need to set RUBY_VM_VM.
-
-	* vm.c (mark_event_hooks): move definition to vm_trace.c.
-
-	* vm.c (ruby_vm_event_flags): add a global variable.
-	  This global variable represents all of Threads and VM's
-	  event masks (T1#events | T2#events | ... | VM#events).
-	  You can check the possibility kick trace func or not
-	  with ruby_vm_event_flags.
-	  ruby_vm_event_flags is maintained by vm_trace.c.

-Fri Jun 22 18:04:26 2012  Koichi Sasada  <ko1@atdot.net>
-
-	* 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.
-
-	* bootstraptest/test_eval.rb: add a test for above.
-
-	* internal.h: remove unused decl.
-
-	* iseq.c (rb_iseq_compile_with_option): add base_block parameter.
-	  set th->base_block before compilation and restore it after
-	  compilation.

-	* ruby.c (require_libraries): pass 0 as base_block instead of
-	  setting th->base_block
-
-	* tool/compile_prelude.rb (prelude_eval): apply above changes.
-
-	* vm.c, vm_eval.c: ditto.
-
-	* vm_core.h: add comments.

-	* 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.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c:

-	* 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

-	  FrameInfo has the following methods:
-	    FrameInfo#name: method name, class name, etc with decorations.
-	    FrameInfo#basename: name without decorations.

-
-	* 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.

-
-	* 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 17:05:07 2012  Koichi Sasada  <ko1@atdot.net>

-
-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.

-	* vm_method.c (rb_method_defined_by): removed.
-	  nobu pointed out that rb_method_basic_definition_p() is enough
-	  for last commit.
-
-	* 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

-	  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.

-
-	* win32/win32.c (finish_overlapped_socket, overlapped_socket_io):
-	  replace ECONNABORTED to EPIPE in send, sendto and sendmsg to improve
-	  BSD socket compatibility.  this change removes a failure on the test
-	  of net/ftp.

-	  similar to `name' field without any decoration.

-	* ext/openssl/ossl_ssl.c: Add SSL constants and allow to unset SSL
-	  option to prevent BEAST attack. See [Bug #5353].
-
-	  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.

-	  fixes: Bug #2729
-	  a patch from Kazuki Tsujimoto <kazuki@callcc.net>
-	  This problem is caused by changing dfp (dynamic env pointer)
-	  from saved dfp.  Saved dfp is pointed env in VM stack.  However,
-	  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
-	  problem, I'll try to change throw mechanism (not save target dfp,
-	  but save target cfp).

-
-	* iseq.h, iseq.c, compile.c: Change the line number data structure
-	  to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217].
-	  Before this fix, each instruction has an information including
-	  line number (iseq::iseq_insn_info_table).  Instead of this data
-	  structure, recording only line number changing places
-	  (iseq::iseq_line_info_table).
-	  The order of entries in iseq_line_info_table is ascending order of
-	  iseq_line_info_table_entry::position.  You can get a line number
-	  by an iseq and a program counter with this data structure.
-	  This fix reduces memory consumption of iseq (bytecode).
-	  On my measurement, a rails application consumes 21.8MB for
-	  iseq with this fix on the 32bit CPU.  Without this fix, it
-	  consumes 24.7MB for iseq [ruby-dev:44415].

-	  result and dumped and loaded iseq disassembed result.

-	  There are several bugs around there, because of inexact stack depth

-
-	* iseq.c (iseq_translate): at the end of constructing an iseq,
-	  call RubyVM::InstructionSequence.translate(iseq) if this method
-	  is defined. If the return value is also an object of
-	  RubyVM::InstructionSequence, then use it instead of created one.
-
-	  For example, this method is useful to test iseq dumper/loader
-	  such as RubyVM::InstructionSequence#to_a and rb_iseq_load().
-
-	  Because this method is for such internal experimental usage,
-	  the interface is not matured. For example, this interface has
-	  no extensibility. Two or more translators can not run
-	  simultaneously.
-
-	  So that we don't guarantee future compatibility of this method.
-	  Basically, do not use this method.

-
-	* 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.
-

-
-	  If exception parameter is truthy, it raises

-	  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.

-	* vm_opts.h, iseq.c, iseq.h: add compile option to force frozen

-
-	  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

-
-	* ext/openssl/ossl_ssl.c (ossl_sslctx_setup): Implement
-	  SSLContext#options and options= using SSL_CTX_set_options and

-	  simplifies `ossl_sslctx_setup`.
-
-	* ext/openssl/lib/openssl/ssl.rb (module OpenSSL): Default `options`

-
-	* ext/openssl/ossl_ssl.c (ossl_call_tmp_dh_callback): change callback
-	  to return the Ruby dh (or ecdh) object that the caller cares about
-	  instead of doing rb_iv_get / set to communicate.  This means we can
-	  remove an rb_iv_get call, and only use the set calls for their
-	  intended purpose (to prevent the object from being GC'd).

-
-	* ext/openssl/ossl_ssl.c (ossl_call_tmp_dh_callback): Similarly to the

-	  SSLContext holds a reference to the tmp_dh_callback.  Ask the
-	  context for the callback instead of storing the callback in two

-	  storing the callback in two places.
-
-Sat Aug  1 03:14:07 2015  Aaron Patterson <tenderlove@ruby-lang.org>
-
-	* ext/openssl/lib/openssl/ssl.rb (module OpenSSL): convert
-	  `tmp_dh_callback` to Ruby, and call it when setting up an SSL
-	  connection.  This allows us to move the "default" behavior to the
-	  reader method.
-
-	* ext/openssl/ossl_ssl.c: call the tmp_dh_callback instead of

-	* make rb_iseq_t T_IMEMO object (type is imemo_iseq).
-
-	  All contents of previous rb_iseq_t is in rb_iseq_t::body.
-	  Remove rb_iseq_t::self because rb_iseq_t is an object.
-
-	  RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
-	  So RubyVM::ISeq.of(something) method returns different wrapper
-	  objects but they point the same T_IMEMO/iseq object.
-
-	  This patch is big, but most of difference is replacement of
-	  iseq->xxx to iseq->body->xxx.
-
-	  (previous) rb_iseq_t::compile_data is also located to
-	  rb_iseq_t::compile_data.
-	  It was moved from rb_iseq_body::compile_data.
-
-	  Now rb_iseq_t has empty two pointers.
-	  I will split rb_iseq_body data into static data and dynamic data.
-
-	* compile.c: rename some functions/macros.
-	  Now, we don't need to separate iseq and iseqval (only VALUE).

-
-	* load.c (rb_load_internal0): rb_iseq_new_top() returns

-
-	* method.h (rb_add_method_iseq): accept rb_iseq_t (T_IMEMO/iseq).

-
-	* 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.
-
-	* class.c (method_entry_i): ditto.
-
-	* class.c (rb_define_attr): rb_method_entry() does not takes

-
-	* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
-	  because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,
-	  execv() in exec_with_sh() and proc_exec_cmd() are never called.
-	  To guarantee this, execv() is replaced by a macro to print
-	  out error message on Solaris 10.
-
-	* 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

-
-	* method.h: split rb_method_definition_t::flag to several flags.
-
-	  `flag' contains several categories of attributes and it makes us
-	  confusion (at least, I had confused).
-
-	  * rb_method_visibility_t (flags::visi)
-	    * NOEX_UNDEF     -> METHOD_VISI_UNDEF     = 0
-	    * NOEX_PUBLIC    -> METHOD_VISI_PUBLIC    = 1

-	  * NOEX_MODFUNC     -> rb_scope_visibility_t in CREF
-	  * NOEX_SUPER       -> MISSING_SUPER (enum missing_reason)
-	  * NOEX_VCALL       -> MISSING_VCALL (enum missing_reason)
-	  * 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
-	  method_missing (NoMethodError) reason.
-
-	* eval_intern.h: introduce rb_scope_visibility_t to represent
-	  scope visibility.
-	  It has 3 method visibilities (public/private/protected)
-	  and `module_function`.

-	  If RGENGC_OLD_NEWOBJ_CHECK > 0, then create old objects
-	  (not new objects) periodically.
-
-	  Create one old objects per RGENGC_OLD_NEWOBJ_CHECK objects are

-
-	* gc.c (check_rvalue_consistency): refactoring.
-	  * not inline on RGENGC_CHECK_MODE > 0.
-	  * check SPECIAL_CONST_P(obj) first.
-	  * add a check that remembered_bit is only TRUE when old (age == 3).
-
-	* gc.c (RVALUE_DEMOTE): should clear RVALUE_REMEMBERED bit.
-
-	  remembered_bit should be TRUE only for old (age == 3) objects.
-
-	  Actually there are no effect because demoted objects will be
-	  uncollectible WB unprotected objects (marked at the beginning of
-	  every minor GC).
-
-Thu Mar 19 02:52:48 2015  Koichi Sasada  <ko1@atdot.net>
-
-	* gc.c: rename terminologies.
-	  * long_lived -> uncollectible:
-	    because this bitmap does not mean "long lived objects in past",
-	    but means "prohibit collection these objects until next major GC".
-
-	    Uncollectible objects consist of two types objects, one is old
-	    objects (WB protected objects which age == 3) and another is
-	    uncollectible WB unprotected objects which are referred from old
-	    objects
-
-	  * remembered_wb_unprotected_objects ->
-	    uncollectible_wb_unprotected_objects:
-	    because uncollectible objects does not mean remembered objects.
-
-Wed Mar 18 17:21:12 2015  Koichi Sasada  <ko1@atdot.net>
-
-	* gc.c (gc_writebarrier_generational): add an alternative write
-	  barrier (WB) implementation.
-	  When finding reference from [Old obj] to [New obj] by WB, current
-	  implementation marks [Old obj] as remembered old objects and marks
-	  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).

-
-Tue Mar 17 18:59:16 2015  Koichi Sasada  <ko1@atdot.net>
-
-	* include/ruby/ruby.h: use rb_gc_writebrrier() simply.
-	  For incremental GC, we need to get a pointer to the objspace.
-	  We can share this pointer for the following WB process.
-	  And considering icache hit ratio, process in the GC.
-
-	* gc.c (rb_gc_writebarrier): added.
-
-	* gc.c (gc_writebarrier_generational, gc_writebarrier_incremental):
-	  make them NOINLINE because inlining them into rb_gc_writebarrier()
-	  makes a prologue code of rb_gc_writebarrier() longer (storing callee
-	  save registers).
-
-	  This patch improve the performance of WB on micro-benchmarks.

-
-	* benchmark/bm_vm1_gc_wb_ary(_promoted).rb: separate fastpath and
-	  slowpath for WB.
-
-	  Before this change bm_vm1_gc_wb_ary.rb tried to check the performance
-	  for WB slowpath (making a reference from oldobj to newobj). However,
-	  from Ruby 2.2, 3 GCs are needed to promote new objects because
-	  only 3 age objects are promoted objects.
-
-	  To compare fastpath and slowpath, introduce new "promoted" version
-	  benchmark.
-
-	  bm_vm1_gc_wb_ary.rb is for fastpath and
-	  bm_vm1_gc_wb_ary_promoted.rb is for slowpath.

-
-	* 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`.
-
-	* class.c: ditto.
-
-	* eval.c (rb_using_refinement): ditto.
-
-	* gc.c: ditto.

-
-	* gc.c (rb_objspace_call_finalizer): control GC execution during
-	  force firnalizations at the end of interpreter process.
-	  [Bug #10768]
-
-	  1) Prohibit incremental GC while running Ruby-level finalizers
-	     to avoid any danger.
-	  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.

+= NEWS for Ruby 2.7.0
+
+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 2.6.0 release
+
+=== Language changes
+
+==== Pattern matching
+
+* Pattern matching is introduced as an experimental feature. [Feature #14912]
+
+    case [0, [1, 2, 3]]
+    in [a, [b, *c]]
+      p a #=> 0
+      p b #=> 1
+      p c #=> [2, 3]
+    end
+
+    case {a: 0, b: 1}
+    in {a: 0, x: 1}
+      :unreachable
+    in {a: 0, b: var}
+      p var #=> 1
+    end
+
+    case -1
+    in 0 then :unreachable
+    in 1 then :unreachable
+    end #=> NoMatchingPatternError
+
+    json = <<END
+    {
+      "name": "Alice",
+      "age": 30,
+      "children": [{ "name": "Bob", "age": 2 }]
+    }
+    END
+
+    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: name, age: age}]}
+
+    p name #=> "Bob"
+    p age  #=> 2
+
+    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: "Charlie", age: age}]}
+    #=> NoMatchingPatternError
+
+* See the following slides for more details:
+  * 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]
+
+[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
+
+[IO]
+
+  [New method]
+
+    * Added IO#set_encoding_by_bom to check the BOM and set the external
+      encoding.  [Bug #15210]
+
+[Integer]
+
+  [Modified method]
+
+    * Integer#[] now supports range operations.  [Feature #8842]
+
+         0b01001101[2, 4]  #=> 0b0011
+         0b01001100[2..5]  #=> 0b0011
+         0b01001100[2...6] #=> 0b0011
+         #   ^^^^
+
+[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]
+
+    * +RubyVM.resolve_feature_path+ moved to
+      <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
+
+[String]
+
+  [Unicode]
+
+    * Update Unicode version and Emoji version from 11.0.0 to
+      12.0.0.  [Feature #15321]
+
+    * Update Unicode version to 12.1.0, adding support for
+      U+32FF SQUARE ERA NAME REIWA.  [Feature #15195]
+
+    * Update Unicode Emoji version to 12.1. [Feature #16272]
+
+[Symbol]
+
+  [New methods]
+
+    * Added Symbol#start_with? and Symbol#end_with? methods.  [Feature #16348]
+
+[Time]
+
+  [New methods]
+
+    * Added Time#ceil method.  [Feature #15772]
+
+    * Added Time#floor method.  [Feature #15653]
+
+  [Modified method]
+
+    * Time#inspect is separated from Time#to_s and it shows
+      the time's sub second.  [Feature #15958]
+
+[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.
+
+          class Foo
+            def add_1(x)
+              x + 1
+            end
+          end
+          class Bar < Foo
+            def add_1(x) # override
+              x + 2
+            end
+          end
+
+          obj = Bar.new
+          p obj.add_1(1) #=> 3
+          p Foo.instance_method(:add_1).bind(obj).call(1) #=> 2
+          p Foo.instance_method(:add_1).bind_call(obj, 1) #=> 2
+
+[Warning]
+
+  [New methods]
+
+    * Added Warning.[] and Warning.[]= to manage emitting/suppressing
+      some categories of warnings.  [Feature #16345] [Feature #16420]
+
+[$LOAD_PATH]
+
+  [New method]
+
+    * Added <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
+
+=== Stdlib updates (outstanding ones only)
+
+[Bundler]
+
+  * Upgrade to Bundler 2.1.2.
+    See https://github.com/bundler/bundler/releases/tag/v2.1.2
+
+[CGI]
+
+  * CGI.escapeHTML becomes 2~5x faster when there is at least one escaped character.
+    See https://github.com/ruby/ruby/pull/2226
+
+[CSV]

+
+[ERB]
+
+  * Prohibit marshaling ERB instance.
+
+[IRB]

+        opts.on("-f", "--foo", "foo") {|v| }
+        opts.on("-b", "--bar", "bar") {|v| }
+        opts.on("-c", "--baz", "baz") {|v| }
+      end.parse!
+
+    example:

+
+  * 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

+## 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 2.7.0
-
-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 2.6.0 release
-
-=== Language changes
-
-==== Pattern matching
-
-* Pattern matching is introduced as an experimental feature. [Feature #14912]
-
-    case [0, [1, 2, 3]]
-    in [a, [b, *c]]
-      p a #=> 0
-      p b #=> 1
-      p c #=> [2, 3]
-    end
-
-    case {a: 0, b: 1}
-    in {a: 0, x: 1}
-      :unreachable
-    in {a: 0, b: var}
-      p var #=> 1
-    end
-
-    case -1
-    in 0 then :unreachable
-    in 1 then :unreachable
-    end #=> NoMatchingPatternError
-
-    json = <<END
-    {
-      "name": "Alice",
-      "age": 30,
-      "children": [{ "name": "Bob", "age": 2 }]
-    }
-    END
-
-    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: name, age: age}]}
-
-    p name #=> "Bob"
-    p age  #=> 2
-
-    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: "Charlie", age: age}]}
-    #=> NoMatchingPatternError
-
-* See the following slides for more details:
-  * 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].

-
-[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.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
-
-[IO]
-
-  [New method]
-
-    * Added IO#set_encoding_by_bom to check the BOM and set the external
-      encoding.  [Bug #15210]
-
-[Integer]
-
-  [Modified method]
-
-    * Integer#[] now supports range operations.  [Feature #8842]
-
-         0b01001101[2, 4]  #=> 0b0011
-         0b01001100[2..5]  #=> 0b0011
-         0b01001100[2...6] #=> 0b0011
-         #   ^^^^
-
-[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]
-
-    * +RubyVM.resolve_feature_path+ moved to
-      <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
-
-[String]
-
-  [Unicode]
-
-    * Update Unicode version and Emoji version from 11.0.0 to
-      12.0.0.  [Feature #15321]
-
-    * Update Unicode version to 12.1.0, adding support for
-      U+32FF SQUARE ERA NAME REIWA.  [Feature #15195]
-
-    * Update Unicode Emoji version to 12.1. [Feature #16272]
-
-[Symbol]
-
-  [New methods]
-
-    * Added Symbol#start_with? and Symbol#end_with? methods.  [Feature #16348]
-
-[Time]
-
-  [New methods]
-
-    * Added Time#ceil method.  [Feature #15772]
-
-    * Added Time#floor method.  [Feature #15653]
-
-  [Modified method]
-
-    * Time#inspect is separated from Time#to_s and it shows
-      the time's sub second.  [Feature #15958]
-
-[UnboundMethod]
-
-  [New method]
-
-    * Added UnboundMethod#bind_call method.  [Feature #15955]
-
-      <code>umethod.bind_call(obj, ...)</code> is semantically equivalent
-      to <code>umethod.bind(obj).call(...)</code>.  This idiom is used in
-      some libraries to call a method that is overridden.  The added
-      method does the same without allocation of an intermediate Method
-      object.
-
-          class Foo
-            def add_1(x)
-              x + 1
-            end
-          end
-          class Bar < Foo
-            def add_1(x) # override
-              x + 2
-            end
-          end
-
-          obj = Bar.new
-          p obj.add_1(1) #=> 3
-          p Foo.instance_method(:add_1).bind(obj).call(1) #=> 2
-          p Foo.instance_method(:add_1).bind_call(obj, 1) #=> 2
-
-[Warning]
-
-  [New methods]
-
-    * Added Warning.[] and Warning.[]= to manage emitting/suppressing
-      some categories of warnings.  [Feature #16345] [Feature #16420]
-
-[$LOAD_PATH]
-
-  [New method]
-
-    * Added <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
-

-
-  * Object#DelegateClass accepts a block and module_evals it in the context
-    of the returned class, similar to Class.new and Struct.new.
-
-[ERB]
-
-  * Prohibit marshaling ERB instance.
-
-[IRB]

-  * Upgrade to 2.3.0.
-
-[Net::FTP]
-
-  * Add Net::FTP#features to check available features, and Net::FTP#option to
-    enable/disable each of them.  [Feature #15964]
-
-[Net::HTTP]
-
-  * Add +ipaddr+ optional parameter to Net::HTTP#start to replace the address for
-    the TCP/IP connection. [Feature #5180]
-
-[Net::IMAP]
-
-  * Add Server Name Indication (SNI) support.  [Feature #15594]
-
-[open-uri]
-
-  * 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

-
-[OptionParser]
-
-  * Now show "Did you mean?" for unknown options.  [Feature #16256]
-
-    test.rb:

-      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
-

-
-=== 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#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]]

-      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.

-
-* 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:

-        * 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]]

-    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]]
-

-  to stop the measurement temporarily, and `Coverage.resume` to restart it.
-  See [[Feature #18176]] in detail.
-
-* 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`.

-# 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]]

-    * 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#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
-
-    * Add support for UNIXSocket on Windows. Emulate anonymous sockets. Add
-      support for File.socket? and File::Stat#socket? where possible.
-      [[Feature #19135]]

-
-See GitHub releases like [GitHub Releases of Logger](https://github.com/ruby/logger/releases) or changelog for details of the default gems or bundled gems.
-
-## 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.

-A {regular expression}[https://en.wikipedia.org/wiki/Regular_expression]
-(also called a _regexp_) is a <i>match pattern</i> (also simply called a _pattern_).
-
-A common notation for a regexp uses enclosing slash characters:
-
-  /foo/
-
-A regexp may be applied to a <i>target string</i>;
-The part of the string (if any) that matches the pattern is called a _match_,
-and may be said <i>to match</i>:
-
-  re = /red/
-  re.match?('redirect') # => true   # Match at beginning of target.
-  re.match?('bored')    # => true   # Match at end of target.
-  re.match?('credit')   # => true   # Match within target.
-  re.match?('foo')      # => false  # No match.
-
-== \Regexp Uses
-
-A regexp may be used:
-
-- To extract substrings based on a given pattern:
-
-    re = /foo/              # => /foo/
-    re.match('food')        # => #<MatchData "foo">
-    re.match('good')        # => nil
-
-  See sections {Method match}[rdoc-ref:Regexp@Method+match]
-  and {Operator =~}[rdoc-ref:Regexp@Operator+-3D~].
-
-- To determine whether a string matches a given pattern:
-
-    re.match?('food') # => true
-    re.match?('good') # => false
-
-  See section {Method match?}[rdoc-ref:Regexp@Method+match-3F].
-
-- As an argument for calls to certain methods in other classes and modules;
-  most such methods accept an argument that may be either a string
-  or the (much more powerful) regexp.
-
-  See {Regexp Methods}[rdoc-ref:regexp/methods.rdoc].
-
-== \Regexp Objects
-
-A regexp object has:
-
-- A source; see {Sources}[rdoc-ref:Regexp@Sources].
-
-- Several modes; see {Modes}[rdoc-ref:Regexp@Modes].
-
-- A timeout; see {Timeouts}[rdoc-ref:Regexp@Timeouts].
-
-- An encoding; see {Encodings}[rdoc-ref:Regexp@Encodings].
-
-== Creating a \Regexp
-
-A regular expression may be created with:
-
-- A regexp literal using slash characters
-  (see {Regexp Literals}[rdoc-ref:syntax/literals.rdoc@Regexp+Literals]):
-
-    # This is a very common usage.
-    /foo/ # => /foo/
-
-- A <tt>%r</tt> regexp literal
-  (see {%r: Regexp Literals}[rdoc-ref:syntax/literals.rdoc@25r-3A+Regexp+Literals]):
-
-    # Same delimiter character at beginning and end;
-    # useful for avoiding escaping characters
-    %r/name\/value pair/ # => /name\/value pair/
-    %r:name/value pair:  # => /name\/value pair/
-    %r|name/value pair|  # => /name\/value pair/
-
-    # Certain "paired" characters can be delimiters.
-    %r[foo] # => /foo/
-    %r{foo} # => /foo/
-    %r(foo) # => /foo/
-    %r<foo> # => /foo/
-
-- \Method Regexp.new.
-
-== \Method <tt>match</tt>
-
-Each of the methods Regexp#match, String#match, and Symbol#match
-returns a MatchData object if a match was found, +nil+ otherwise;
-each also sets {global variables}[rdoc-ref:Regexp@Global+Variables]:
-
-  'food'.match(/foo/) # => #<MatchData "foo">
-  'food'.match(/bar/) # => nil
-
-== Operator <tt>=~</tt>
-
-Each of the operators Regexp#=~, String#=~, and Symbol#=~
-returns an integer offset if a match was found, +nil+ otherwise;
-each also sets {global variables}[rdoc-ref:Regexp@Global+Variables]:
-
-  /bar/ =~ 'foo bar' # => 4
-  'foo bar' =~ /bar/ # => 4
-  /baz/ =~ 'foo bar' # => nil
-
-== \Method <tt>match?</tt>
-
-Each of the methods Regexp#match?, String#match?, and Symbol#match?
-returns +true+ if a match was found, +false+ otherwise;
-none sets {global variables}[rdoc-ref:Regexp@Global+Variables]:
-
-  'food'.match?(/foo/) # => true
-  'food'.match?(/bar/) # => false
-
-== Global Variables
-
-Certain regexp-oriented methods assign values to global variables:
-
-- <tt>#match</tt>: see {Method match}[rdoc-ref:Regexp@Method+match].
-- <tt>#=~</tt>: see {Operator =~}[rdoc-ref:Regexp@Operator+-3D~].
-
-The affected global variables are:
-
-- <tt>$~</tt>: Returns a MatchData object, or +nil+.
-- <tt>$&</tt>: Returns the matched part of the string, or +nil+.
-- <tt>$`</tt>: Returns the part of the string to the left of the match, or +nil+.
-- <tt>$'</tt>: Returns the part of the string to the right of the match, or +nil+.
-- <tt>$+</tt>: Returns the last group matched, or +nil+.
-- <tt>$1</tt>, <tt>$2</tt>, etc.: Returns the first, second, etc.,
-  matched group, or +nil+.
-  Note that <tt>$0</tt> is quite different;
-  it returns the name of the currently executing program.
-
-Examples:
-
-  # Matched string, but no matched groups.
-  'foo bar bar baz'.match('bar')
-  $~ # => #<MatchData "bar">
-  $& # => "bar"
-  $` # => "foo "
-  $' # => " bar baz"
-  $+ # => nil
-  $1 # => nil
-
-  # Matched groups.
-  /s(\w{2}).*(c)/.match('haystack')
-  $~ # => #<MatchData "stac" 1:"ta" 2:"c">
-  $& # => "stac"
-  $` # => "hay"
-  $' # => "k"
-  $+ # => "c"
-  $1 # => "ta"
-  $2 # => "c"
-  $3 # => nil
-
-  # No match.
-  'foo'.match('bar')
-  $~ # => nil
-  $& # => nil
-  $` # => nil
-  $' # => nil
-  $+ # => nil
-  $1 # => nil
-
-Note that Regexp#match?, String#match?, and Symbol#match?
-do not set global variables.
-
-== Sources
-
-As seen above, the simplest regexp uses a literal expression as its source:
-
-  re = /foo/              # => /foo/
-  re.match('food')        # => #<MatchData "foo">
-  re.match('good')        # => nil
-
-A rich collection of available _subexpressions_
-gives the regexp great power and flexibility:
-

-- {Source literals}[rdoc-ref:Regexp@Source+Literals]
-- {Character classes}[rdoc-ref:Regexp@Character+Classes]
-- {Shorthand character classes}[rdoc-ref:Regexp@Shorthand+Character+Classes]

-
-=== Special Characters
-
-\Regexp special characters, called _metacharacters_,
-have special meanings in certain contexts;
-depending on the context, these are sometimes metacharacters:
-
-  . ? - + * ^ \ | $ ( ) [ ] { }
-
-To match a metacharacter literally, backslash-escape it:
-
-  # Matches one or more 'o' characters.
-  /o+/.match('foo')  # => #<MatchData "oo">
-  # Would match 'o+'.
-  /o\+/.match('foo') # => nil
-
-To match a backslash literally, backslash-escape it:
-
-  /\./.match('\.')  # => #<MatchData ".">
-  /\\./.match('\.') # => #<MatchData "\\.">
-
-Method Regexp.escape returns an escaped string:
-
-  Regexp.escape('.?-+*^\|$()[]{}')
-  # => "\\.\\?\\-\\+\\*\\^\\\\\\|\\$\\(\\)\\[\\]\\{\\}"
-
-=== Source Literals
-
-The source literal largely behaves like a double-quoted string;
-see {String Literals}[rdoc-ref:syntax/literals.rdoc@String+Literals].
-
-In particular, a source literal may contain interpolated expressions:
-
-  s = 'foo'         # => "foo"
-  /#{s}/            # => /foo/
-  /#{s.capitalize}/ # => /Foo/
-  /#{2 + 2}/        # => /4/
-
-There are differences between an ordinary string literal and a source literal;
-see {Shorthand Character Classes}[rdoc-ref:Regexp@Shorthand+Character+Classes].
-
-- <tt>\s</tt> in an ordinary string literal is equivalent to a space character;
-  in a source literal, it's shorthand for matching a whitespace character.
-- In an ordinary string literal, these are (needlessly) escaped characters;
-  in a source literal, they are shorthands for various matching characters:
-
-    \w \W \d \D \h \H \S \R
-
-=== Character Classes
-
-A <i>character class</i> is delimited by square brackets;
-it specifies that certain characters match at a given point in the target string:
-
-  # This character class will match any vowel.
-  re = /B[aeiou]rd/
-  re.match('Bird') # => #<MatchData "Bird">
-  re.match('Bard') # => #<MatchData "Bard">
-  re.match('Byrd') # => nil
-
-A character class may contain hyphen characters to specify ranges of characters:
-
-  # These regexps have the same effect.
-  /[abcdef]/.match('foo') # => #<MatchData "f">
-  /[a-f]/.match('foo')    # => #<MatchData "f">
-  /[a-cd-f]/.match('foo') # => #<MatchData "f">
-
-When the first character of a character class is a caret (<tt>^</tt>),
-the sense of the class is inverted: it matches any character _except_ those specified.
-
-  /[^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]/
-
-=== Shorthand Character Classes
-
-Each of the following metacharacters serves as a shorthand
-for a character class:
-
-- <tt>/./</tt>: Matches any character except a newline:
-
-    /./.match('foo') # => #<MatchData "f">
-    /./.match("\n")  # => nil
-
-- <tt>/./m</tt>: Matches any character, including a newline;
-  see {Multiline Mode}[rdoc-ref:Regexp@Multiline+Mode]:
-
-    /./m.match("\n") # => #<MatchData "\n">
-
-- <tt>/\w/</tt>: Matches a word character: equivalent to <tt>[a-zA-Z0-9_]</tt>:
-
-    /\w/.match(' foo') # => #<MatchData "f">
-    /\w/.match(' _')   # => #<MatchData "_">
-    /\w/.match(' ')    # => nil
-
-- <tt>/\W/</tt>: Matches a non-word character: equivalent to <tt>[^a-zA-Z0-9_]</tt>:
-
-    /\W/.match(' ') # => #<MatchData " ">
-    /\W/.match('_') # => nil
-
-- <tt>/\d/</tt>: Matches a digit character: equivalent to <tt>[0-9]</tt>:
-
-    /\d/.match('THX1138') # => #<MatchData "1">
-    /\d/.match('foo')     # => nil
-
-- <tt>/\D/</tt>: Matches a non-digit character: equivalent to <tt>[^0-9]</tt>:
-
-    /\D/.match('123Jump!') # => #<MatchData "J">
-    /\D/.match('123')      # => nil
-
-- <tt>/\h/</tt>: Matches a hexdigit character: equivalent to <tt>[0-9a-fA-F]</tt>:
-
-    /\h/.match('xyz fedcba9876543210') # => #<MatchData "f">
-    /\h/.match('xyz')                  # => nil
-
-- <tt>/\H/</tt>: Matches a non-hexdigit character: equivalent to <tt>[^0-9a-fA-F]</tt>:
-
-    /\H/.match('fedcba9876543210xyz') # => #<MatchData "x">
-    /\H/.match('fedcba9876543210')    # => nil
-
-- <tt>/\s/</tt>: Matches a whitespace character: equivalent to <tt>/[ \t\r\n\f\v]/</tt>:
-
-    /\s/.match('foo bar') # => #<MatchData " ">
-    /\s/.match('foo')     # => nil
-
-- <tt>/\S/</tt>: Matches a non-whitespace character: equivalent to <tt>/[^ \t\r\n\f\v]/</tt>:
-
-    /\S/.match(" \t\r\n\f\v foo") # => #<MatchData "f">
-    /\S/.match(" \t\r\n\f\v")     # => nil
-
-- <tt>/\R/</tt>: Matches a linebreak, platform-independently:
-
-    /\R/.match("\r")     # => #<MatchData "\r">     # Carriage return (CR)
-    /\R/.match("\n")     # => #<MatchData "\n">     # Newline (LF)
-    /\R/.match("\f")     # => #<MatchData "\f">     # Formfeed (FF)
-    /\R/.match("\v")     # => #<MatchData "\v">     # Vertical tab (VT)
-    /\R/.match("\r\n")   # => #<MatchData "\r\n">   # CRLF
-    /\R/.match("\u0085") # => #<MatchData "\u0085"> # Next line (NEL)
-    /\R/.match("\u2028") # => #<MatchData "\u2028"> # Line separator (LSEP)
-    /\R/.match("\u2029") # => #<MatchData "\u2029"> # Paragraph separator (PSEP)
-
-=== Anchors
-
-An anchor is a metasequence that matches a zero-width position between
-characters in the target string.
-
-For a subexpression with no anchor,
-matching may begin anywhere in the target string:
-
-  /real/.match('surrealist') # => #<MatchData "real">
-
-For a subexpression with an anchor,
-matching must begin at the matched anchor.
-
-==== Boundary Anchors
-
-Each of these anchors matches a boundary:
-
-- <tt>^</tt>: Matches the beginning of a line:
-
-    /^bar/.match("foo\nbar") # => #<MatchData "bar">
-    /^ar/.match("foo\nbar")  # => nil
-
-- <tt>$</tt>: Matches the end of a line:
-
-    /bar$/.match("foo\nbar") # => #<MatchData "bar">
-    /ba$/.match("foo\nbar")  # => nil
-
-- <tt>\A</tt>: Matches the beginning of the string:
-
-    /\Afoo/.match('foo bar')  # => #<MatchData "foo">
-    /\Afoo/.match(' foo bar') # => nil
-
-- <tt>\Z</tt>: Matches the end of the string;
-  if string ends with a single newline,
-  it matches just before the ending newline:
-
-    /foo\Z/.match('bar foo')     # => #<MatchData "foo">
-    /foo\Z/.match('foo bar')     # => nil
-    /foo\Z/.match("bar foo\n")   # => #<MatchData "foo">
-    /foo\Z/.match("bar foo\n\n") # => nil
-
-- <tt>\z</tt>: Matches the end of the string:
-
-    /foo\z/.match('bar foo')   # => #<MatchData "foo">
-    /foo\z/.match('foo bar')   # => nil
-    /foo\z/.match("bar foo\n") # => nil
-
-- <tt>\b</tt>: Matches word boundary when not inside brackets;
-  matches backspace (<tt>"0x08"</tt>) when inside brackets:
-
-    /foo\b/.match('foo bar') # => #<MatchData "foo">
-    /foo\b/.match('foobar')  # => nil
-
-- <tt>\B</tt>: Matches non-word boundary:
-
-    /foo\B/.match('foobar')  # => #<MatchData "foo">
-    /foo\B/.match('foo bar') # => nil
-
-- <tt>\G</tt>: Matches first matching position:
-
-  In methods like String#gsub and String#scan, 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 Regexp#match and String#match
-  that take an optional offset, it matches where the search begins.
-
-    "hello, world".match(/,/, 3)   # => #<MatchData ",">
-    "hello, world".match(/\G,/, 3) # => nil
-
-==== Lookaround Anchors
-
-Lookahead anchors:
-
-- <tt>(?=_pat_)</tt>: Positive lookahead assertion:
-  ensures that the following characters match _pat_,
-  but doesn't include those characters in the matched substring.
-
-- <tt>(?!_pat_)</tt>: Negative lookahead assertion:
-  ensures that the following characters <i>do not</i> match _pat_,
-  but doesn't include those characters in the matched substring.
-
-Lookbehind anchors:
-
-- <tt>(?<=_pat_)</tt>: Positive lookbehind assertion:
-  ensures that the preceding characters match _pat_, but
-  doesn't include those characters in the matched substring.
-
-- <tt>(?<!_pat_)</tt>: Negative lookbehind assertion:
-  ensures that the preceding characters do not match
-  _pat_, but doesn't include those characters in the matched substring.
-
-The pattern below uses positive lookahead and positive lookbehind to match
-text appearing in <tt><b></tt>...<tt></b></tt> tags
-without including the tags in the match:
-
-  /(?<=<b>)\w+(?=<\/b>)/.match("Fortune favors the <b>bold</b>.")
-  # => #<MatchData "bold">
-
-==== Match-Reset Anchor
-
-- <tt>\K</tt>: Match reset:
-  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/.match('abc')    # => #<MatchData "c">
-    /(?<=ab)c/.match('abc') # => #<MatchData "c">
-
-  These match same string and <tt>$&</tt> equals <tt>'c'</tt>,
-  while the matched position is different.
-
-  As are the following two regexps:
-
-    /(a)\K(b)\Kc/
-    /(?<=(?<=(a))(b))c/
-
-=== Alternation
-
-The vertical bar metacharacter (<tt>|</tt>) may be used within parentheses
-to express alternation:
-two or more subexpressions any of which may match the target string.
-
-Two alternatives:
-
-  re = /(a|b)/
-  re.match('foo') # => nil
-  re.match('bar') # => #<MatchData "b" 1:"b">
-
-Four alternatives:
-
-  re = /(a|b|c|d)/
-  re.match('shazam') # => #<MatchData "a" 1:"a">
-  re.match('cold')   # => #<MatchData "c" 1:"c">
-
-Each alternative is a subexpression, and may be composed of other subexpressions:
-
-  re = /([a-c]|[x-z])/
-  re.match('bar') # => #<MatchData "b" 1:"b">
-  re.match('ooz') # => #<MatchData "z" 1:"z">
-
-\Method Regexp.union provides a convenient way to construct
-a regexp with alternatives.
-
-=== Quantifiers
-
-A simple regexp matches one character:
-
-  /\w/.match('Hello')  # => #<MatchData "H">
-
-An added _quantifier_ specifies how many matches are required or allowed:
-
-- <tt>*</tt> - Matches zero or more times:
-
-    /\w*/.match('')
-    # => #<MatchData "">
-    /\w*/.match('x')
-    # => #<MatchData "x">
-    /\w*/.match('xyz')
-    # => #<MatchData "yz">
-
-- <tt>+</tt> - Matches one or more times:
-
-    /\w+/.match('')    # => nil
-    /\w+/.match('x')   # => #<MatchData "x">
-    /\w+/.match('xyz') # => #<MatchData "xyz">
-
-- <tt>?</tt> - Matches zero or one times:
-
-    /\w?/.match('')    # => #<MatchData "">
-    /\w?/.match('x')   # => #<MatchData "x">
-    /\w?/.match('xyz') # => #<MatchData "x">
-
-- <tt>{</tt>_n_<tt>}</tt> - Matches exactly _n_ times:
-
-    /\w{2}/.match('')    # => nil
-    /\w{2}/.match('x')   # => nil
-    /\w{2}/.match('xyz') # => #<MatchData "xy">
-
-- <tt>{</tt>_min_<tt>,}</tt> - Matches _min_ or more times:
-
-    /\w{2,}/.match('')    # => nil
-    /\w{2,}/.match('x')   # => nil
-    /\w{2,}/.match('xy')  # => #<MatchData "xy">
-    /\w{2,}/.match('xyz') # => #<MatchData "xyz">
-
-- <tt>{,</tt>_max_<tt>}</tt> - Matches _max_ or fewer times:
-
-    /\w{,2}/.match('')    # => #<MatchData "">
-    /\w{,2}/.match('x')   # => #<MatchData "x">
-    /\w{,2}/.match('xyz') # => #<MatchData "xy">
-
-- <tt>{</tt>_min_<tt>,</tt>_max_<tt>}</tt> -
-  Matches at least _min_ times and at most _max_ times:
-
-    /\w{1,2}/.match('')    # => nil
-    /\w{1,2}/.match('x')   # => #<MatchData "x">
-    /\w{1,2}/.match('xyz') # => #<MatchData "xy">
-
-==== Greedy, Lazy, or Possessive Matching
-
-Quantifier matching may be greedy, lazy, or possessive:
-
-- In _greedy_ matching, as many occurrences as possible are matched
-  while still allowing the overall match to succeed.
-  Greedy quantifiers: <tt>*</tt>, <tt>+</tt>, <tt>?</tt>,
-  <tt>{min, max}</tt> and its variants.
-- In _lazy_ matching, the minimum number of occurrences are matched.
-  Lazy quantifiers: <tt>*?</tt>, <tt>+?</tt>, <tt>??</tt>,
-  <tt>{min, max}?</tt> and its variants.
-- In _possessive_ matching, once a match is found, there is no backtracking;
-  that match is retained, even if it jeopardises the overall match.
-  Possessive quantifiers: <tt>*+</tt>, <tt>++</tt>, <tt>?+</tt>.
-  Note that <tt>{min, max}</tt> and its variants do _not_ support possessive matching.
-

-=== Groups and Captures
-
-A simple regexp has (at most) one match:
-
-  re = /\d\d\d\d-\d\d-\d\d/
-  re.match('1943-02-04')      # => #<MatchData "1943-02-04">
-  re.match('1943-02-04').size # => 1
-  re.match('foo')             # => nil
-
-Adding one or more pairs of parentheses, <tt>(_subexpression_)</tt>,
-defines _groups_, which may result in multiple matched substrings,
-called _captures_:
-
-  re = /(\d\d\d\d)-(\d\d)-(\d\d)/
-  re.match('1943-02-04')      # => #<MatchData "1943-02-04" 1:"1943" 2:"02" 3:"04">
-  re.match('1943-02-04').size # => 4
-
-The first capture is the entire matched string;
-the other captures are the matched substrings from the groups.
-
-A group may have a {quantifier}[rdoc-ref:Regexp@Quantifiers]:
-
-  re = /July 4(th)?/
-  re.match('July 4')   # => #<MatchData "July 4" 1:nil>
-  re.match('July 4th') # => #<MatchData "July 4th" 1:"th">
-
-  re = /(foo)*/
-  re.match('')       # => #<MatchData "" 1:nil>
-  re.match('foo')    # => #<MatchData "foo" 1:"foo">
-  re.match('foofoo') # => #<MatchData "foofoo" 1:"foo">
-
-  re = /(foo)+/
-  re.match('')       # => nil
-  re.match('foo')    # => #<MatchData "foo" 1:"foo">
-  re.match('foofoo') # => #<MatchData "foofoo" 1:"foo">
-
-The returned \MatchData object gives access to the matched substrings:
-
-  re = /(\d\d\d\d)-(\d\d)-(\d\d)/
-  md = re.match('1943-02-04')
-  # => #<MatchData "1943-02-04" 1:"1943" 2:"02" 3:"04">
-  md[0] # => "1943-02-04"
-  md[1] # => "1943"
-  md[2] # => "02"
-  md[3] # => "04"
-
-==== Non-Capturing Groups
-
-A group may be made non-capturing;
-it is still a group (and, for example, can have a quantifier),
-but its matching substring is not included among the captures.
-
-A non-capturing group begins with <tt>?:</tt> (inside the parentheses):
-
-  # Don't capture the year.
-  re = /(?:\d\d\d\d)-(\d\d)-(\d\d)/
-  md = re.match('1943-02-04') # => #<MatchData "1943-02-04" 1:"02" 2:"04">
-
-==== Backreferences
-
-A group match may also be referenced within the regexp itself;
-such a reference is called a +backreference+:
-
-  /[csh](..) [csh]\1 in/.match('The cat sat in the hat')
-  # => #<MatchData "cat sat in" 1:"at">
-
-This table shows how each subexpression in the regexp above
-matches a substring in the target string:
-
-  | Subexpression in Regexp   | Matching Substring in Target String |
-  |---------------------------|-------------------------------------|
-  |       First '[csh]'       |            Character 'c'            |
-  |          '(..)'           |        First substring 'at'         |
-  |      First space ' '      |      First space character ' '      |
-  |       Second '[csh]'      |            Character 's'            |
-  | '\1' (backreference 'at') |        Second substring 'at'        |
-  |           ' in'           |            Substring ' in'          |
-
-A regexp may contain any number of groups:
-
-- For a large number of groups:
-
-  - The ordinary <tt>\\_n_</tt> notation applies only for _n_ in range (1..9).
-  - The <tt>MatchData[_n_]</tt> notation applies for any non-negative _n_.
-
-- <tt>\0</tt> is a special backreference, referring to the entire matched string;
-  it may not be used within the regexp itself,
-  but may be used outside it (for example, in a substitution method call):
-
-    'The cat sat in the hat'.gsub(/[csh]at/, '\0s')
-    # => "The cats sats in the hats"
-
-==== Named Captures
-
-As seen above, a capture can be referred to by its number.
-A capture can also have a name,
-prefixed as <tt>?<_name_></tt> or <tt>?'_name_'</tt>,
-and the name (symbolized) may be used as an index in <tt>MatchData[]</tt>:
-
-  md = /\$(?<dollars>\d+)\.(?'cents'\d+)/.match("$3.67")
-  # => #<MatchData "$3.67" dollars:"3" cents:"67">
-  md[:dollars]  # => "3"
-  md[:cents]    # => "67"
-  # The capture numbers are still valid.
-  md[2]         # => "67"
-
-When a regexp contains a named capture, there are no unnamed captures:
-
-  /\$(?<dollars>\d+)\.(\d+)/.match("$3.67")
-  # => #<MatchData "$3.67" dollars:"3">
-
-A named group may be backreferenced as <tt>\k<_name_></tt>:
-
-  /(?<vowel>[aeiou]).\k<vowel>.\k<vowel>/.match('ototomy')
-  # => #<MatchData "ototo" vowel:"o">
-
-When (and only when) a regexp contains named capture groups
-and appears before the <tt>=~</tt> operator,
-the captured substrings are assigned to local variables with corresponding names:
-
-  /\$(?<dollars>\d+)\.(?<cents>\d+)/ =~ '$3.67'
-  dollars # => "3"
-  cents   # => "67"
-
-\Method Regexp#named_captures returns a hash of the capture names and substrings;
-method Regexp#names returns an array of the capture names.
-
-==== Atomic Grouping
-
-A group may be made _atomic_ with <tt>(?></tt>_subexpression_<tt>)</tt>.
-
-This causes the subexpression to be matched
-independently of the rest of the expression,
-so that the matched substring becomes fixed for the remainder of the match,
-unless the entire subexpression must be abandoned and subsequently revisited.
-
-In this way _subexpression_ is treated as a non-divisible whole.
-Atomic grouping is typically used to optimise patterns
-to prevent needless backtracking .
-
-Example (without atomic grouping):
-
-  /".*"/.match('"Quote"') # => #<MatchData "\"Quote\"">
-
-Analysis:
-
-1. The leading subexpression <tt>"</tt> in the pattern matches the first character
-   <tt>"</tt> in the target string.
-2. The next subexpression <tt>.*</tt> matches the next substring <tt>Quote“</tt>
-   (including the trailing double-quote).
-3. Now there is nothing left in the target string to match
-   the trailing subexpression <tt>"</tt> in the pattern;
-   this would cause the overall match to fail.
-4. The matched substring is backtracked by one position: <tt>Quote</tt>.
-5. The final subexpression <tt>"</tt> now matches the final substring <tt>"</tt>,
-   and the overall match succeeds.
-
-If subexpression <tt>.*</tt> is grouped atomically,
-the backtracking is disabled, and the overall match fails:
-
-  /"(?>.*)"/.match('"Quote"') # => nil
-
-Atomic grouping can affect performance;
-see {Atomic Group}[https://www.regular-expressions.info/atomic.html].
-
-==== Subexpression Calls
-
-As seen above, a backreference number (<tt>\\_n_</tt>) or name (<tt>\k<_name_></tt>)
-gives access to a captured _substring_;
-the corresponding regexp _subexpression_ may also be accessed,
-via the number (<tt>\\g<i>n</i></tt>) or name (<tt>\g<_name_></tt>):
-
-  /\A(?<paren>\(\g<paren>*\))*\z/.match('(())')
-  # ^1
-  #      ^2
-  #           ^3
-  #                 ^4
-  #      ^5
-  #           ^6
-  #                      ^7
-  #                       ^8
-  #                       ^9
-  #                           ^10
-
-The pattern:
-
-1.  Matches at the beginning of the string, i.e. before the first character.
-2.  Enters a named group +paren+.
-3.  Matches the first character in the string, <tt>'('</tt>.
-4.  Calls the +paren+ group again, i.e. recurses back to the  second step.
-5.  Re-enters the +paren+ group.
-6.  Matches the second character in the string, <tt>'('</tt>.
-7.  Attempts to call +paren+ a third time,
-    but fails because doing so would prevent an overall successful match.
-8.  Matches the third character in the string, <tt>')'</tt>;
-    marks the end of the second recursive call
-9.  Matches the fourth character in the string, <tt>')'</tt>.
-10. Matches the end of the string.
-
-See {Subexpression calls}[https://learnbyexample.github.io/Ruby_Regexp/groupings-and-backreferences.html?highlight=subexpression#subexpression-calls].
-
-==== Conditionals
-
-The conditional construct takes the form <tt>(?(_cond_)_yes_|_no_)</tt>, where:
-
-- _cond_ may be a capture number or name.
-- The match to be applied is _yes_ if _cond_ is captured;
-  otherwise the match to be applied is _no_.
-- If not needed, <tt>|_no_</tt> may be omitted.
-
-Examples:
-
-  re = /\A(foo)?(?(1)(T)|(F))\z/
-  re.match('fooT') # => #<MatchData "fooT" 1:"foo" 2:"T" 3:nil>
-  re.match('F')    # => #<MatchData "F" 1:nil 2:nil 3:"F">
-  re.match('fooF') # => nil
-  re.match('T')    # => nil
-
-  re = /\A(?<xyzzy>foo)?(?(<xyzzy>)(T)|(F))\z/
-  re.match('fooT') # => #<MatchData "fooT" xyzzy:"foo">
-  re.match('F')    # => #<MatchData "F" xyzzy:nil>
-  re.match('fooF') # => nil
-  re.match('T')    # => nil
-
-
-==== Absence Operator
-
-The absence operator is a special group that matches anything which does _not_ match the contained subexpressions.
-
-  /(?~real)/.match('surrealist') # => #<MatchData "surrea">
-  /(?~real)ist/.match('surrealist') # => #<MatchData "ealist">
-  /sur(?~real)ist/.match('surrealist') # => nil
-
-=== Unicode
-
-==== Unicode Properties
-
-The <tt>/\p{_property_name_}/</tt> construct (with lowercase +p+)
-matches characters using a Unicode property name,
-much like a character class;
-property +Alpha+ specifies alphabetic characters:
-
-  /\p{Alpha}/.match('a') # => #<MatchData "a">
-  /\p{Alpha}/.match('1') # => nil
-
-A property can be inverted
-by prefixing the name with a caret character (<tt>^</tt>):
-
-  /\p{^Alpha}/.match('1') # => #<MatchData "1">
-  /\p{^Alpha}/.match('a') # => nil
-
-Or by using <tt>\P</tt> (uppercase +P+):
-
-  /\P{Alpha}/.match('1') # => #<MatchData "1">
-  /\P{Alpha}/.match('a') # => nil
-
-See {Unicode Properties}[rdoc-ref:regexp/unicode_properties.rdoc]
-for regexps based on the numerous properties.
-
-Some commonly-used properties correspond to POSIX bracket expressions:
-
-- <tt>/\p{Alnum}/</tt>: Alphabetic and numeric character
-- <tt>/\p{Alpha}/</tt>: Alphabetic character
-- <tt>/\p{Blank}/</tt>: Space or tab
-- <tt>/\p{Cntrl}/</tt>: Control character
-- <tt>/\p{Digit}/</tt>: Digit
-  characters, and similar)
-- <tt>/\p{Lower}/</tt>: Lowercase alphabetical character
-- <tt>/\p{Print}/</tt>: Like <tt>\p{Graph}</tt>, but includes the space character
-- <tt>/\p{Punct}/</tt>: Punctuation character
-- <tt>/\p{Space}/</tt>: Whitespace character (<tt>[:blank:]</tt>, newline,
-  carriage return, etc.)
-- <tt>/\p{Upper}/</tt>: Uppercase alphabetical
-- <tt>/\p{XDigit}/</tt>: Digit allowed in a hexadecimal number (i.e., 0-9a-fA-F)
-
-These are also commonly used:
-
-- <tt>/\p{Emoji}/</tt>: Unicode emoji.
-- <tt>/\p{Graph}/</tt>: Non-blank character
-  (excludes spaces, control characters, and similar).
-- <tt>/\p{Word}/</tt>: A member in one of these Unicode character
-  categories (see below) or having one of these Unicode properties:
-
-  - Unicode categories:
-    - +Mark+ (+M+).
-    - <tt>Decimal Number</tt> (+Nd+)
-    - <tt>Connector Punctuation</tt> (+Pc+).
-
-  - Unicode properties:
-    - +Alpha+
-    - <tt>Join_Control</tt>
-
-- <tt>/\p{ASCII}/</tt>: A character in the ASCII character set.
-- <tt>/\p{Any}/</tt>: Any Unicode character (including unassigned characters).
-- <tt>/\p{Assigned}/</tt>: An assigned character.
-
-==== Unicode Character Categories
-
-A Unicode character category name:
-
-- May be either its full name or its abbreviated name.
-- Is case-insensitive.
-- Treats a space, a hyphen, and an underscore as equivalent.
-
-Examples:
-
-  /\p{lu}/                # => /\p{lu}/
-  /\p{LU}/                # => /\p{LU}/
-  /\p{Uppercase Letter}/  # => /\p{Uppercase Letter}/
-  /\p{Uppercase_Letter}/  # => /\p{Uppercase_Letter}/
-  /\p{UPPERCASE-LETTER}/  # => /\p{UPPERCASE-LETTER}/

-==== Unicode Scripts and Blocks
-
-Among the Unicode properties are:
-
-- {Unicode scripts}[https://en.wikipedia.org/wiki/Script_(Unicode)];
-  see {supported scripts}[https://www.unicode.org/standard/supported.html].
-- {Unicode blocks}[https://en.wikipedia.org/wiki/Unicode_block];
-  see {supported blocks}[http://www.unicode.org/Public/UNIDATA/Blocks.txt].
-
-=== POSIX Bracket Expressions
-
-A POSIX <i>bracket expression</i> is also similar to a character class.
-These expressions provide a portable alternative to the above,
-with the added benefit of encompassing non-ASCII characters:
-
-- <tt>/\d/</tt> matches only ASCII decimal digits +0+ through +9+.
-- <tt>/[[:digit:]]/</tt> matches any character in the Unicode
-  <tt>Decimal Number</tt> (+Nd+) category;
-  see below.
-
-The POSIX bracket expressions:
-
-- <tt>/[[:digit:]]/</tt>: Matches a {Unicode digit}[https://www.compart.com/en/unicode/category/Nd]:
-
-    /[[:digit:]]/.match('9')       # => #<MatchData "9">
-    /[[:digit:]]/.match("\u1fbf9") # => #<MatchData "9">
-
-- <tt>/[[:xdigit:]]/</tt>: Matches a digit allowed in a hexadecimal number;
-  equivalent to <tt>[0-9a-fA-F]</tt>.
-
-- <tt>/[[:upper:]]/</tt>: Matches a {Unicode uppercase letter}[https://www.compart.com/en/unicode/category/Lu]:
-
-    /[[:upper:]]/.match('A')      # => #<MatchData "A">
-    /[[:upper:]]/.match("\u00c6") # => #<MatchData "Æ">
-
-- <tt>/[[:lower:]]/</tt>: Matches a {Unicode lowercase letter}[https://www.compart.com/en/unicode/category/Ll]:
-
-    /[[:lower:]]/.match('a')      # => #<MatchData "a">
-    /[[:lower:]]/.match("\u01fd") # => #<MatchData "ǽ">
-
-- <tt>/[[:alpha:]]/</tt>: Matches <tt>/[[:upper:]]/</tt> or <tt>/[[:lower:]]/</tt>.
-
-- <tt>/[[:alnum:]]/</tt>: Matches <tt>/[[:alpha:]]/</tt> or <tt>/[[:digit:]]/</tt>.
-
-- <tt>/[[:space:]]/</tt>: Matches {Unicode space character}[https://www.compart.com/en/unicode/category/Zs]:
-
-    /[[:space:]]/.match(' ')      # => #<MatchData " ">
-    /[[:space:]]/.match("\u2005") # => #<MatchData " ">
-
-- <tt>/[[:blank:]]/</tt>: Matches <tt>/[[:space:]]/</tt> or tab character:
-
-    /[[:blank:]]/.match(' ')      # => #<MatchData " ">
-    /[[:blank:]]/.match("\u2005") # => #<MatchData " ">
-    /[[:blank:]]/.match("\t")     # => #<MatchData "\t">
-
-- <tt>/[[:cntrl:]]/</tt>: Matches {Unicode control character}[https://www.compart.com/en/unicode/category/Cc]:
-
-    /[[:cntrl:]]/.match("\u0000") # => #<MatchData "\u0000">
-    /[[:cntrl:]]/.match("\u009f") # => #<MatchData "\u009F">
-
-- <tt>/[[:graph:]]/</tt>: Matches any character
-  except <tt>/[[:space:]]/</tt> or <tt>/[[:cntrl:]]/</tt>.
-
-- <tt>/[[:print:]]/</tt>: Matches <tt>/[[:graph:]]/</tt> or space character.
-
-- <tt>/[[:punct:]]/</tt>: Matches any (Unicode punctuation character}[https://www.compart.com/en/unicode/category/Po]:
-
-Ruby also supports these (non-POSIX) bracket expressions:
-
-- <tt>/[[:ascii:]]/</tt>: Matches a character in the ASCII character set.
-- <tt>/[[:word:]]/</tt>: Matches a character in one of these Unicode character
-  categories or having one of these Unicode properties:
-
-  - Unicode categories:
-    - +Mark+ (+M+).
-    - <tt>Decimal Number</tt> (+Nd+)
-    - <tt>Connector Punctuation</tt> (+Pc+).

-    - <tt>Join_Control</tt>
-
-=== Comments
-
-A comment may be included in a regexp pattern
-using the <tt>(?#</tt>_comment_<tt>)</tt> construct,
-where _comment_ is a substring that is to be ignored.
-arbitrary text ignored by the regexp engine:
-
-  /foo(?#Ignore me)bar/.match('foobar') # => #<MatchData "foobar">
-
-The comment may not include an unescaped terminator character.
-
-See also {Extended Mode}[rdoc-ref:Regexp@Extended+Mode].
-
-== Modes
-
-Each of these modifiers sets a mode for the regexp:
-
-- +i+: <tt>/_pattern_/i</tt> sets
-  {Case-Insensitive Mode}[rdoc-ref:Regexp@Case-Insensitive+Mode].
-- +m+: <tt>/_pattern_/m</tt> sets
-  {Multiline Mode}[rdoc-ref:Regexp@Multiline+Mode].
-- +x+: <tt>/_pattern_/x</tt> sets
-  {Extended Mode}[rdoc-ref:Regexp@Extended+Mode].
-- +o+: <tt>/_pattern_/o</tt> sets
-  {Interpolation Mode}[rdoc-ref:Regexp@Interpolation+Mode].
-
-Any, all, or none of these may be applied.
-
-Modifiers +i+, +m+, and +x+ may be applied to subexpressions:
-
-- <tt>(?_modifier_)</tt> turns the mode "on" for ensuing subexpressions
-- <tt>(?-_modifier_)</tt> turns the mode "off" for ensuing subexpressions
-- <tt>(?_modifier_:_subexp_)</tt> turns the mode "on" for _subexp_ within the group
-- <tt>(?-_modifier_:_subexp_)</tt> turns the mode "off" for _subexp_ within the group
-
-Example:
-
-  re = /(?i)te(?-i)st/
-  re.match('test') # => #<MatchData "test">
-  re.match('TEst') # => #<MatchData "TEst">
-  re.match('TEST') # => nil
-  re.match('teST') # => nil
-  
-  re = /t(?i:e)st/
-  re.match('test') # => #<MatchData "test">
-  re.match('tEst') # => #<MatchData "tEst">
-  re.match('tEST') # => nil
-
-\Method Regexp#options returns an integer whose value showing
-the settings for case-insensitivity mode, multiline mode, and extended mode.
-
-=== Case-Insensitive Mode
-
-By default, a regexp is case-sensitive:
-
-  /foo/.match('FOO')  # => nil
-
-Modifier +i+ enables case-insensitive mode:
-
-  /foo/i.match('FOO')
-  # => #<MatchData "FOO">
-
-\Method Regexp#casefold? returns whether the mode is case-insensitive.
-
-=== Multiline Mode
-
-The multiline-mode in Ruby is what is commonly called a "dot-all mode":
-
-- Without the +m+ modifier, the subexpression <tt>.</tt> does not match newlines:
-
-    /a.c/.match("a\nc")  # => nil
-
-- With the modifier, it does match:
-
-    /a.c/m.match("a\nc") # => #<MatchData "a\nc">
-
-Unlike other languages, the modifier +m+ does not affect the anchors <tt>^</tt> and <tt>$</tt>.
-These anchors always match at line-boundaries in Ruby.
-
-=== Extended Mode
-
-Modifier +x+ enables extended mode, which means that:
-
-- Literal white space in the pattern is to be ignored.
-- Character <tt>#</tt> marks the remainder of its containing line as a comment,
-  which is also to be ignored for matching purposes.
-
-In extended mode, whitespace and comments may be used
-to form a self-documented regexp.
-
-Regexp not in extended mode (matches some Roman numerals):
-
-  pattern = '^M{0,3}(CM|CD|D?C{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})$'
-  re = /#{pattern}/
-  re.match('MCMXLIII') # => #<MatchData "MCMXLIII" 1:"CM" 2:"XL" 3:"III">
-
-Regexp in extended mode:
-
-  pattern = <<-EOT
-    ^                   # beginning of string
-    M{0,3}              # thousands - 0 to 3 Ms
-    (CM|CD|D?C{0,3})    # hundreds - 900 (CM), 400 (CD), 0-300 (0 to 3 Cs),
-                        #            or 500-800 (D, followed by 0 to 3 Cs)
-    (XC|XL|L?X{0,3})    # tens - 90 (XC), 40 (XL), 0-30 (0 to 3 Xs),
-                        #        or 50-80 (L, followed by 0 to 3 Xs)
-    (IX|IV|V?I{0,3})    # ones - 9 (IX), 4 (IV), 0-3 (0 to 3 Is),
-                        #        or 5-8 (V, followed by 0 to 3 Is)
-    $                   # end of string
-  EOT
-  re = /#{pattern}/x
-  re.match('MCMXLIII') # => #<MatchData "MCMXLIII" 1:"CM" 2:"XL" 3:"III">
-
-=== Interpolation Mode
-
-Modifier +o+ means that the first time a literal regexp with interpolations
-is encountered,
-the generated Regexp object is saved and used for all future evaluations
-of that literal regexp.
-Without modifier +o+, the generated Regexp is not saved,
-so each evaluation of the literal regexp generates a new Regexp object.
-
-Without modifier +o+:
-
-  def letters; sleep 5; /[A-Z][a-z]/; end
-  words = %w[abc def xyz]
-  start = Time.now
-  words.each {|word| word.match(/\A[#{letters}]+\z/) }
-  Time.now - start # => 15.0174892
-
-With modifier +o+:
-
-  start = Time.now
-  words.each {|word| word.match(/\A[#{letters}]+\z/o) }
-  Time.now - start # => 5.0010866
-
-Note that if the literal regexp does not have interpolations,
-the +o+ behavior is the default.
-
-== Encodings
-
-By default, a regexp with only US-ASCII characters has US-ASCII encoding:
-
-  re = /foo/
-  re.source.encoding # => #<Encoding:US-ASCII>
-  re.encoding        # => #<Encoding:US-ASCII>
-
-A regular expression containing non-US-ASCII characters
-is assumed to use the source encoding.
-This can be overridden with one of the following modifiers.
-
-- <tt>/_pat_/n</tt>: US-ASCII if only containing US-ASCII characters,
-  otherwise ASCII-8BIT:
-
-    /foo/n.encoding     # => #<Encoding:US-ASCII>
-    /foo\xff/n.encoding # => #<Encoding:ASCII-8BIT>
-    /foo\x7f/n.encoding # => #<Encoding:US-ASCII>
-
-- <tt>/_pat_/u</tt>: UTF-8
-
-    /foo/u.encoding # => #<Encoding:UTF-8>
-
-- <tt>/_pat_/e</tt>: EUC-JP
-
-    /foo/e.encoding # => #<Encoding:EUC-JP>
-
-- <tt>/_pat_/s</tt>: Windows-31J
-
-    /foo/s.encoding # => #<Encoding:Windows-31J>
-
-A regexp can be matched against a target string when either:
-
-- They have the same encoding.
-- The regexp's encoding is a fixed encoding and the string
-  contains only ASCII characters.
-  Method Regexp#fixed_encoding? returns whether the regexp
-  has a <i>fixed</i> encoding.
-
-If a match between incompatible encodings is attempted an
-<tt>Encoding::CompatibilityError</tt> exception is raised.
-
-Example:
-
-  re = eval("# encoding: ISO-8859-1\n/foo\\xff?/")
-  re.encoding                 # => #<Encoding:ISO-8859-1>
-  re =~ "foo".encode("UTF-8") # => 0
-  re =~ "foo\u0100"           # Raises Encoding::CompatibilityError
-
-The encoding may be explicitly fixed by including Regexp::FIXEDENCODING
-in the second argument for Regexp.new:
-
-  # Regexp with encoding ISO-8859-1.
-  re = Regexp.new("a".force_encoding('iso-8859-1'), Regexp::FIXEDENCODING)
-  re.encoding  # => #<Encoding:ISO-8859-1>
-  # Target string with encoding UTF-8.
-  s = "a\u3042"
-  s.encoding   # => #<Encoding:UTF-8>
-  re.match(s)  # Raises Encoding::CompatibilityError.
-
-== Timeouts
-
-When either a regexp source or a target string comes from untrusted input,
-malicious values could become a denial-of-service attack;
-to prevent such an attack, it is wise to set a timeout.
-
-\Regexp has two timeout values:
-
-- A class default timeout, used for a regexp whose instance timeout is +nil+;
-  this default is initially +nil+, and may be set by method Regexp.timeout=:
-
-    Regexp.timeout # => nil
-    Regexp.timeout = 3.0
-    Regexp.timeout # => 3.0
-
-- An instance timeout, which defaults to +nil+ and may be set in Regexp.new:
-
-    re = Regexp.new('foo', timeout: 5.0)
-    re.timeout # => 5.0
-
-When regexp.timeout is +nil+, the timeout "falls through" to Regexp.timeout;
-when regexp.timeout is non-+nil+, that value controls timing out:
-
-  | regexp.timeout Value | Regexp.timeout Value |            Result           |
-  |----------------------|----------------------|-----------------------------|
-  |         nil          |          nil         |       Never times out.      |
-  |         nil          |         Float        | Times out in Float seconds. |
-  |        Float         |          Any         | Times out in Float seconds. |
-
-== Optimization
-
-For certain values of the pattern and target string,
-matching time can grow polynomially or exponentially in relation to the input size;
-the potential vulnerability arising from this is the {regular expression denial-of-service}[https://en.wikipedia.org/wiki/ReDoS] (ReDoS) attack.
-
-\Regexp matching can apply an optimization to prevent ReDoS attacks.
-When the optimization is applied, matching time increases linearly (not polynomially or exponentially)
-in relation to the input size, and a ReDoS attach is not possible.
-
-This optimization is applied if the pattern meets these criteria:
-
-- No backreferences.
-- No subexpression calls.
-- No nested lookaround anchors or atomic groups.
-- No nested quantifiers with counting (i.e. no nested <tt>{n}</tt>,
-  <tt>{min,}</tt>, <tt>{,max}</tt>, or <tt>{min,max}</tt> style quantifiers)
-
-You can use method Regexp.linear_time? to determine whether a pattern meets these criteria:
-
-  Regexp.linear_time?(/a*/)     # => true
-  Regexp.linear_time?('a*')     # => true
-  Regexp.linear_time?(/(a*)\1/) # => false
-
-However, an untrusted source may not be safe even if the method returns +true+,
-because the optimization uses memoization (which may invoke large memory consumption).

-== 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:Time@Hours-2FMinutes+Offsets].
-- {Single-letter offset}[rdoc-ref:Time@Single-Letter+Offsets].
-- {Integer offset}[rdoc-ref:Time@Integer+Offsets].
-- {Timezone object}[rdoc-ref:Time@Timezone+Objects].
-- {Timezone name}[rdoc-ref:Time@Timezone+Names].
-
-=== 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
-
-The zone value may be an object responding to certain timezone methods, an
-instance of {Timezone}[https://github.com/panthomakos/timezone] and
-{TZInfo}[https://tzinfo.github.io] for example.
-
-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 {Time-like object}[rdoc-ref:Time@Time-Like+Objects].
-  - Returns: a {Time-like object}[rdoc-ref:Time@Time-Like+Objects] 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 {Time-like object}[rdoc-ref:Time@Time-Like+Objects].
-  - Returns: a {Time-like object}[rdoc-ref:Time@Time-Like+Objects] 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 {Time-like object}[rdoc-ref:Time@Time-Like+Objects].
-  - 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 {Time-like object}[rdoc-ref:Time@Time-Like+Objects].
-  - Returns: whether the time is daylight saving time.
-
-- +name+:
-
-  - Called when <tt>Marshal.dump(t)</tt> is invoked
-  - Argument: none.
-  - Returns: the string name of the timezone.
-
-==== +Time+-Like Objects
-
-A +Time+-like object is a container object capable of interfacing with
-timezone libraries for timezone conversion.
-
-The argument to the timezone conversion methods above will have attributes
-similar to Time, except that timezone related attributes are meaningless.
-
-The objects returned by +local_to_utc+ and +utc_to_local+ methods of the
-timezone object may be of the same class as their arguments, of arbitrary
-object classes, or of class Integer.
-
-For a returned class other than +Integer+, the class must have the
-following methods:
-
-- +year+
-- +mon+
-- +mday+
-- +hour+
-- +min+
-- +sec+
-- +isdst+
-- +to_i+
-
-For a returned +Integer+, its components, decomposed in UTC, are
-interpreted as times in the specified timezone.
-
-=== Timezone Names
-
-If the class (the receiver of class methods, or the class of the receiver
-of instance methods) has +find_timezone+ singleton method, this method is
-called to achieve the corresponding timezone object from a timezone name.
-
-For example, using {Timezone}[https://github.com/panthomakos/timezone]:
-    class TimeWithTimezone < Time
-      require 'timezone'
-      def self.find_timezone(z) = Timezone[z]
-    end
-
-    TimeWithTimezone.now(in: "America/New_York")        #=> 2023-12-25 00:00:00 -0500
-    TimeWithTimezone.new("2023-12-25 America/New_York") #=> 2023-12-25 00:00:00 -0500
-
-Or, using {TZInfo}[https://tzinfo.github.io]:
-    class TimeWithTZInfo < Time
-      require 'tzinfo'
-      def self.find_timezone(z) = TZInfo::Timezone.get(z)
-    end
-
-    TimeWithTZInfo.now(in: "America/New_York")          #=> 2023-12-25 00:00:00 -0500
-    TimeWithTZInfo.new("2023-12-25 America/New_York")   #=> 2023-12-25 00:00:00 -0500
-
-You can define this method per subclasses, or on the toplevel Time class.

-= 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"
-  '!@#$%&*()_+'.delete('+&#') # => "!@$%*()_"
-  'те�т'.delete('т')          # => "е�"
-  '�ん���'.delete('�')     # => "�ん��"
-
-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')

+= Contributing to Ruby
+
+Ruby has a vast and friendly community with hundreds of people contributing to
+a thriving open-source ecosystem. This guide is designed to cover ways for
+participating in the development of CRuby.
+
+There are plenty of ways for you to help even if you're not ready to write
+code or documentation.  You can help by reporting issues, testing patches, and
+trying out beta releases with your applications.
+
+== How To Report
+
+If you've encountered a bug in Ruby please report it to the redmine issue
+tracker available at {bugs.ruby-lang.org}[https://bugs.ruby-lang.org/].  Do not
+report security vulnerabilities here, there is a {separate
+channel}[rdoc-label:label-Reporting+Security+Issues] for them.
+
+There are a few simple steps you should follow in order to receive feedback
+on your ticket.
+
+* If you haven't already,
+  {sign up for an account}[https://bugs.ruby-lang.org/account/register] on the
+  bug tracker.
+* Try the latest version.
+
+  If you aren't already using the latest version, try installing a newer
+  stable release. See
+  {Downloading Ruby}[https://www.ruby-lang.org/en/downloads/].
+* Look to see if anyone already reported your issue, try
+  {searching on redmine}[https://bugs.ruby-lang.org/projects/ruby-master/issues]
+  for your problem.
+* If you can't find a ticket addressing your issue,
+  {create a new one}[https://bugs.ruby-lang.org/projects/ruby-master/issues/new].
+* Choose the target version, usually current. Bugs will be first fixed in the
+  current release and then {backported}[rdoc-label:label-Backport+Requests].
+* Fill in the Ruby version you're using when experiencing this issue
+  (<code>ruby -v</code>).
+* Attach any logs or reproducible programs to provide additional information.
+  Reproducible scripts should be as small as possible.
+* Briefly describe your problem.  A 2-3 sentence description will help give a
+  quick response.
+* Pick a category, such as core for common problems, or lib for a standard
+  library.
+* Check the {Maintainers
+  list}[https://bugs.ruby-lang.org/projects/ruby/wiki/Maintainers] and assign
+  the ticket if there is an active maintainer for the library or feature.
+* If the ticket doesn't have any replies after 10 days, you can send a
+  reminder.
+* Please reply to feedback requests. If a bug report doesn't get any feedback,
+  it'll eventually get rejected.
+
+=== Reporting to downstream distributions
+
+You can report downstream issues for the following distributions via their bug tracker:
+
+* {debian}[https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=ruby-defaults]
+* {freebsd}[http://www.freebsd.org/cgi/query-pr-summary.cgi?text=ruby]
+* {redhat}[https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=MODIFIED]
+* {macports}[https://trac.macports.org/query?status=assigned&status=new&status=reopened&port=~ruby]
+* etc (add your distribution bug tracker here)
+
+== Reporting Security Issues
+
+Security vulnerabilities receive special treatment since they may negatively
+affect many users. There is a private mailing list that all security issues
+should be reported to and will be handled discretely. Email the
+mailto:security@ruby-lang.org list and the problem will be published after
+fixes have been released. You can also encrypt the issue using {the PGP public
+key}[https://www.ruby-lang.org/security.asc] for the list.
+
+== Reporting Other Issues
+
+If you're having an issue with the website, or maybe the mailing list, you can
+contact the webmaster to help resolve the problem.
+
+The current webmaster is:
+
+* Hiroshi SHIBATA (hsbt)
+
+You can also report issues with the ruby-lang.org website on the issue tracker:
+
+* {issue tracker}[https://github.com/ruby/www.ruby-lang.org/issues]
+
+== Resolve Existing Issues
+
+As a next step beyond reporting issues you can help the core team resolve
+existing issues. If you check the Everyone's Issues list in GitHub Issues,
+you will find a lot of issues already requiring attention. What can you do for
+these? Quite a bit, actually:
+
+When a bug report goes for a while without any feedback, it goes to the bug
+graveyard which is unfortunate. If you check the {issues
+list}[https://bugs.ruby-lang.org/projects/ruby-master/issues] you will find lots
+of delinquent bugs that require attention.
+
+You can help by verifying the existing tickets, try to reproduce the reported
+issue on your own and comment if you still experience the bug. Some issues
+lack attention because of too much ambiguity, to help you can narrow down the
+problem and provide more specific details or instructions to reproduce the
+bug. You might also try contributing a failing test in the form of a patch,
+which we will cover later in this guide.
+
+It may also help to try out patches other contributors have submitted to
+redmine, if gone without notice. In this case the +patch+ command is your
+friend, see <code>man patch</code> for more information. Basically this would
+go something like this:
+
+  cd path/to/ruby
+  patch -p0 < path/to/patch
+
+You will then be prompted to apply the patch with the associated files. After
+building ruby again, you should try to run the tests and verify if the change
+actually worked or fixed the bug. It's important to provide valuable feedback
+on the patch that can help reach the overall goal, try to answer some of these
+questions:
+
+* What do you like about this change?
+* What would you do differently?
+* Are there any other edge cases not tested?
+* Is there any documentation that would be affected by this change?
+
+If you can answer some or all of these questions, you're on the right track.
+If your comment simply says "+1", then odds are that other reviewers aren't
+going to take it too seriously. Show that you took the time to review the
+patch.
+
+== How To Request Features
+
+If there's a new feature that you want to see added to Ruby, you will need to
+write a convincing proposal and patch to implement the feature.
+
+For new features in CRuby, use the {'Feature'
+tracker}[https://bugs.ruby-lang.org/projects/ruby-master/issues?set_filter=1&tracker_id=2]
+on ruby-master. For non-CRuby dependent features, features that would apply to
+alternate Ruby implementations such as JRuby and Rubinius, use the {CommonRuby
+tracker}[https://bugs.ruby-lang.org/projects/common-ruby].
+
+When writing a proposal be sure to check for previous discussions on the
+topic and have a solid use case. You will need to be persuasive and convince
+Matz on your new feature. 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. Although feature
+requests can seem like an alluring way to contribute to Ruby, often these
+discussions can lead nowhere and exhaust time and energy that could be better
+spent fixing bugs. Choose your battles.
+
+A good template for a feature proposal should look something like this:
+
+[Abstract]
+  Summary of your feature
+[Background]
+  Describe current behavior and why it is problem. Related work, such as
+  solutions in other language helps us to understand the problem.
+[Proposal]
+  Describe your proposal in details
+[Details]
+  If it has complicated feature, describe it
+[Usecase]
+  How would your feature be used? Who will benefit from it?
+[Discussion]
+  Discuss about this proposal. A list of pros and cons will help start
+  discussion.
+[Limitation]
+  Limitation of your proposal
+[Another alternative proposal]
+  If there are alternative proposals, show them.
+[See also]
+  Links to the other related resources
+
+== Backport Requests
+
+When a new version of Ruby is released, it starts at patch level 0 (p0), and
+bugs will be fixed first on the master branch. If it's determined that a bug
+exists in a previous version of Ruby that is still in the bug fix stage of
+maintenance, then a patch will be backported. After the maintenance stage of a
+particular Ruby version ends, it goes into "security fix only" mode which
+means only security related vulnerabilities will be backported. Versions in
+End-of-life (EOL) will not receive any updates and it is recommended you
+upgrade as soon as possible.
+
+If a major security issue is found or after a certain amount of time since the
+last patch level release, a new patch-level release will be made.
+
+When submitting a backport request please confirm the bug has been fixed in
+newer versions and exists in maintenance mode versions. There is a backport
+tracker for each major version still in maintenance where you can request a
+particular revision merged in the affected version of Ruby.
+
+Each major version of Ruby has a release manager that should be assigned to
+handle backport requests. You can find the list of release managers on the
+{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
+
+=== Branches
+
+Status and maintainers of branches are listed on the
+{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
+
+== Running tests
+
+In order to help resolve existing issues and contributing patches to Ruby you
+need to be able to run the test suite.
+
+CRuby uses git for source control, the {git homepage}[https://git-scm.com/]
+has installation instructions with links to documentation for learning more
+about git. There is a mirror of the repository on {github}[https://github.com/ruby/ruby].
+For other resources see the {ruby-core documentation on
+ruby-lang.org}[https://www.ruby-lang.org/en/community/ruby-core/].
+
+Install the prerequisite dependencies for building the CRuby interpreter to
+run tests.
+
+* C compiler
+* autoconf - 2.67 or later, preferably 2.69.
+* bison - 2.0 or later, preferably 3.4.
+* gperf - 3.0.3 or later, preferably 3.1.
+* ruby - Ruby itself is prerequisite in order to build Ruby from source.
+  You should use [a maintained version of Ruby](https://www.ruby-lang.org/en/downloads/).
+
+You should also have access to development headers for the following
+libraries, but these are not required:
+
+* NDBM/QDBM
+* GDBM
+* OpenSSL/LibreSSL
+* readline/editline(libedit)
+* zlib
+* libffi
+* libyaml
+* libexecinfo (FreeBSD)
+
+Now let's build CRuby:
+
+* Checkout the CRuby source code:
+
+    git clone https://github.com/ruby/ruby.git ruby-master
+
+* Generate the configuration files and build:
+
+    cd ruby-master
+    ./autogen.sh
+    mkdir build && cd build # its good practice to build outside of source dir
+    mkdir ~/.rubies # we will install to .rubies/ruby-master in our home dir
+    ../configure --prefix="${HOME}/.rubies/ruby-master"
+    make up && make install
+
+After adding Ruby to your PATH, you should be ready to run the test suite:
+
+    make test
+
+You can also use +test-all+ to run all of the tests with the RUNRUBY
+interpreter just built. Use TESTS or RUNRUBYOPT to pass parameters, such as:
+
+    make test-all TESTS=-v
+
+This is also how you can run a specific test from our build dir:
+
+    make test-all TESTS=drb/test_drb.rb
+
+You can run +test+ and +test-all+ at once by +check+ .
+
+    make check
+
+For older versions of Ruby you will need to run the build setup again after
+checking out the associated branch in git, for example if you wanted to
+checkout 1.9.3:
+
+    git clone https://github.com/ruby/ruby.git --branch ruby_1_9_3
+
+Once you checked out the source code, you can update the local copy by:
+
+    make up
+
+Or, update, build, install and check, by just:
+
+    make love
+
+== Contributing Documentation
+
+If you're interested in contributing documentation directly to CRuby there is
+some information available at
+{Contributing}[https://github.com/ruby/ruby#contributing].
+
+There is also the {Ruby Reference
+Manual}[https://github.com/rurema/doctree/wiki] in Japanese.
+
+== Contributing A Patch
+
+=== Deciding what to patch
+
+Before you submit a patch, there are a few things you should know:
+
+* Pay attention to the maintenance policy for stable and maintained versions of Ruby.
+* Released versions in security mode will not merge feature changes.
+* Search for previous discussions on ruby-core to verify the maintenance policy
+* Patches must be distributed under Ruby's license.
+* This license may change in the future, you must join the discussion if you don't agree to the change
+
+To improve the chance your patch will be accepted please follow these simple rules:
+
+* Bug fixes should be committed on master first
+* Format of the patch file must be a unified diff (ie: diff -pu, svn diff, or git diff)
+* Don't introduce cosmetic changes
+* Follow the original coding style of the code
+* Don't mix different changes in one commit
+
+First thing you should do is check out the code if you haven't already:
+
+  git clone https://github.com/ruby/ruby.git ruby-master
+
+Now create a dedicated branch:
+
+  cd ruby-master
+  git checkout -b my_new_branch
+
+The name of your branch doesn't really matter because it will only exist on
+your local computer and won't be part of the official Ruby repository. It will
+be used to create patches based on the differences between your branch and
+master, or edge Ruby.
+
+=== Coding style
+
+Here are some general rules to follow when writing Ruby and C code for CRuby:
+
+* Indent 4 spaces for C without tabs (old codes might use tabs for eight-space indentation,
+  but newer codes recommend to use spaces only)
+* Indent 2 space tabs for Ruby
+* Do not use TABs in ruby codes
+* ANSI C style for 1.9+ for function declarations
+* Follow C90 (not C99) Standard
+* PascalStyle for class/module names.
+* UNDERSCORE_SEPARATED_UPPER_CASE for other constants.
+* Capitalize words.
+* ABBRs should be all upper case.
+* Do as others do
+
+=== Commit messages
+
+When you're ready to commit:
+
+   git commit path/to/files
+
+This will open your editor in which you write your commit message.
+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 redmine issue (such as Fixes [Bug #1234] or Implements
+  [Feature #3456]), or discussion on the mailing list
+  (such as [ruby-core:12345]).
+* For GitHub issues, use [GH-#] (such as [Fixes GH-234]).
+* Follow the style used by other committers.
+
+=== Contributing your code
+
+Now that you've got some code you want to contribute, let's get set up to
+generate a patch. Start by forking the github mirror, check the {github docs on
+forking}[https://help.github.com/articles/fork-a-repo] if you get stuck here.
+You will only need a github account if you intend to host your repository
+on github.
+
+Next copy the writable url for your fork and add it as a git remote, replace
+"my_username" with your github account name:
+
+    git remote add my_fork git@github.com:my_username/ruby.git
+    # Now we can push our branch to our fork
+    git push my_fork my_new_branch
+
+In order to generate a patch that you can upload to the bug tracker, we can use
+the github interface to review our changes just visit
+https://github.com/my_username/ruby/compare/master...my_new_branch
+
+Next, you can simply add '.patch' to the end of this URL and it will generate
+the patch for you, save the file to your computer and upload it to the bug
+tracker. Alternatively you can submit a pull request, but for the best chances
+to receive feedback add it is recommended you add it to redmine.
+
+Since git is a distributed system, you are welcome to host your git repository
+on any {publicly accessible hosting
+site}[https://git.wiki.kernel.org/index.php/GitHosting], including {hosting your
+own}[https://www.kernel.org/pub/software/scm/git/docs/user-manual.html#public-repositories]
+You may use the {'git format-patch'}[https://git-scm.com/docs/git-format-patch]
+command to generate patch files to upload to redmine.  You may also use
+the {'git request-pull'}[https://git-scm.com/docs/git-request-pull] command for
+formatting pull request messages to redmine.
+
+=== Updating the official repository
+
+If you are a committer, you can push changes directly into the official
+repository:
+
+    git push origin your-branch-name:master
+
+However, it is likely will have become outdated, and you will have to
+update it.  In that case, run:
+
+    git fetch origin
+    git rebase remotes/origin/master
+
+and then try pushing your changes again.

-2. Install optional, recommended dependencies:
-
-    * libffi (to build fiddle)
-    * gmp (if you with to accelerate Bignum operations)
-    * libexecinfo (FreeBSD)
-    * rustc - 1.58.0 or later, if you wish to build
-      [YJIT](https://docs.ruby-lang.org/en/master/RubyVM/YJIT.html).
-
-    If you installed the libraries needed for extensions (openssl, readline, libyaml, zlib) into other than the OS default place,
-    typically using Homebrew on macOS, add `--with-EXTLIB-dir` options to `CONFIGURE_ARGS` environment variable.
-
-    ``` shell
-    export CONFIGURE_ARGS=""
-    for ext in openssl readline libyaml zlib; do
-      CONFIGURE_ARGS="${CONFIGURE_ARGS} --with-$ext-dir=$(brew --prefix $ext)"
-    done
-    ```
-
-## Quick start guide
-
-1. Download ruby source code:
-
-    Select one of the bellow.
-
-    1. Build from the tarball:
-
-        Download the latest tarball from [ruby-lang.org](https://www.ruby-lang.org/en/downloads/) and
-        extract it. Example for Ruby 3.0.2:
-
-        ``` shell
-        tar -xzf ruby-3.0.2.tar.gz
-        cd ruby-3.0.2
-        ```
-
-    2. Build from the git repository:
-
-        Checkout the CRuby source code:
-
-        ``` shell
-        git clone https://github.com/ruby/ruby.git
-        cd ruby
-        ```
-
-        Generate the configure file:
-
-        ``` shell
-        ./autogen.sh
-        ```
-
-2. Create a `build` directory separate from the source directory:
-
-    ``` shell
-    mkdir build && cd build
-    ```
-
-    While it's not necessary to build in a separate directory, it's good practice to do so.
-
-3. We'll install Ruby in `~/.rubies/ruby-master`, so create the directory:
-
-    ``` shell
-    mkdir ~/.rubies
-    ```
-
-4. Run configure:
-
-    ``` shell
-    ../configure --prefix="${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.
-
-    - Also `-C` (or `--config-cache`) would reduce time to configure from the next time.
-
-5. Build Ruby:
-
-    ``` shell
-    make install
-    ```
-
-6. [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.
-
-## Building on Windows
-
-The documentation for building on Windows can be found [here](../windows.md).
-
-## 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:
-
-``` shell
-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:
-
-``` shell
-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
-
-### Compiling for Debugging
-
-You should configure Ruby without optimization and other flags that may interfere with debugging:
-
-``` shell
-./configure --enable-debug-env optflags="-O0 -fno-omit-frame-pointer"
-```
-
-### 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.
-
-``` shell
-./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

-# Documentation Guide
-
-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
-```
-
-If you don't have a build directory, follow the [quick start
-guide](building_ruby.md#label-Quick+start+guide) up to step 4.
-
-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 information 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
-  [headings](rdoc-ref:RDoc::MarkupReference@Headings).
-- Refer to authoritative and relevant sources using
-  [links](rdoc-ref:RDoc::MarkupReference@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::MarkupReference@Lists).
-    - Idioms and culture-specific references.
-    - Overuse of headings.
-    - 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]
-```
-
-### Headings
-
-Organize a long discussion for a class or module with [headings](rdoc-ref:RDoc::MarkupReference@Headings).
-
-Do not use formal headings in the documentation for a method or constant.
-
-In the rare case where heading-like structures are needed
-within the documentation for a method or constant, use
-[bold text](rdoc-ref:RDoc::MarkupReference@Bold)
-as pseudo-headings.
-
-### Blank Lines
-
-A blank line begins a new paragraph.
-
-A [code block](rdoc-ref:RDoc::MarkupReference@Code+Blocks)
-or [list](rdoc-ref:RDoc::MarkupReference@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>.
-
-### Embedded Code and Commands
-
-Code or commands embedded in running text (i.e., not in a code block)
-should marked up as
-[monofont](rdoc-ref:RDoc::MarkupReference@Monofont).
-
-Code that is a simple string should include the quote marks.
-
-### 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).
-- The reference is to a class or module that users
-  usually don't deal with, including these:
-
-    - \Class.
-    - \Method.
-    - \Module.
-
-Most often, the name of a class, module, or method
-will be autolinked:
-
-- Array.
-- Enumerable.
-- File.new
-- File#read.
-
-If not, or if you suppress autolinking, consider forcing
-[monofont](rdoc-ref:RDoc::MarkupReference@Monofont).
-
-### Explicit Links
-
-When writing an explicit link, follow these guidelines.
-
-#### +rdoc-ref+ Scheme
-
-Use the +rdoc-ref+ scheme for:
-
-- A link in core documentation to other core documentation.
-- A link in core documentation to documentation in a standard library package.
-- A link in a standard library package to other documentation in that same
-  standard library package.
-
-See section "+rdoc-ref+ Scheme" in {Links}[rdoc-ref:RDoc::MarkupReference@Links].
-
-#### URL-Based Link
-
-Use a full URL-based link for:
-
-- A link in standard library documentation to documentation in the core.
-- A link in standard library documentation to documentation in a different
-  standard library package.
-
-Doing so ensures that the link will valid even when the package documentation
-is built independently (separately from the core documentation).
-
-The link should lead to a target in https://docs.ruby-lang.org/en/master/.
-
-Also use a full URL-based link for a link to an off-site document.
-
-### Variable Names
-
-The name of a variable (as specified in its call-seq) should be marked up as
-[monofont](rdoc-ref:RDoc::MarkupReference@Monofont).
-
-Also, use monofont text for the name of a transient variable
-(i.e., one defined and used only in the discussion, such as +n+).
-
-### 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:
-
-- 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:
-
-    - Example {source}[https://github.com/ruby/ruby/blob/34d802f32f00df1ac0220b62f72605827c16bad8/file.c#L6570-L6596].
-    - Corresponding {output}[rdoc-ref:File@Read-2FWrite+Mode].
-
-- (Markdown format only): A {Github Flavored Markdown (GFM) table}[https://github.github.com/gfm/#tables-extension-],
-  using special formatting for the text:
-
-    - Example {source}[https://github.com/ruby/ruby/blob/34d802f32f00df1ac0220b62f72605827c16bad8/doc/contributing/glossary.md?plain=1].
-    - Corresponding {output}[https://docs.ruby-lang.org/en/master/contributing/glossary_md.html].
-
-## 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::MarkupReference@Links)
-  to their "What's Here" sections if those exist.
-- All methods mentioned in the left-pane table of contents
-  should be listed (including any methods extended from another class).
-- Attributes (which are not included in the TOC) may also be listed.
-- Display methods as items in one or more bullet lists:
-
-    - 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::MarkupReference@Links).
-
-- If there are numerous entries, consider grouping them into subsections with headings.
-- 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.
-- 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::MarkupReference@Directives+for+Method+Documentation).
-
-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`, unless the alias is an
-  operator method. If listing both a regular method and an
-  operator method in the `call-seq`, explain in the details and
-  examples section when it is recommended to use the regular method
-  and when it is recommended to use the operator method.
-
-### 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::MarkupReference@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`.
-
-### 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.

-Just a list of acronyms I've run across in the Ruby source code and their meanings.
-
-| Term | Definition |
-| ---  | -----------|
-| `BIN` | Basic Instruction Name. Used as a macro to reference the YARV instruction. Converts pop into YARVINSN_pop. |
-| `bop` | Basic Operator. Relates to methods like `Integer` plus and minus which can be optimized as long as they haven't been redefined. |
-| `cc` | Call Cache.  An inline cache structure for the call site. Stored in the `cd` |
-| `cd` | Call Data. A data structure that points at the `ci` and the `cc`.  `iseq` objects points at the `cd`, and access call information and call caches via this structure |
-| `cfp`| Control Frame Pointer. Represents a Ruby stack frame.  Calling a method pushes a new frame (cfp), returning pops a frame. Points at  the `pc`, `sp`, `ep`, and the corresponding `iseq`|
-| `ci` | Call Information.  Refers to an `rb_callinfo` struct. Contains call information about the call site, including number of parameters to be passed, whether it they are keyword arguments or not, etc. Used in conjunction with the `cc` and `cd`. |
-| `cref` | Class reference. A structure pointing to the class reference where `klass_or_self`, visibility scope, and refinements are stored. It also stores a pointer to the next class in the hierarchy referenced by `rb_cref_struct * next`. The Class reference is lexically scoped. |
-| CRuby | Implementation of Ruby written in C |
-| `cvar` | Class Variable. Refers to a Ruby class variable like `@@foo` |
-| `dvar` | Dynamic Variable. Used by the parser to refer to local variables that are defined outside of the current lexical scope. For example `def foo; bar = 1; -> { p bar }; end` the "bar" inside the block is a `dvar` |
-| `ec` | Execution Context. The top level VM context, points at the current `cfp` |
-| `ep` | Environment Pointer. Local variables, including method parameters are stored in the `ep` array. The `ep` is pointed to by the `cfp` |
-| GC | Garbage Collector |
-| `gvar` | Global Variable. Refers to a Ruby global variable like `$$`, etc |
-| `ICLASS` | Internal Class. When a module is included, the target class gets a new superclass which is an instance of an `ICLASS`. The `ICLASS` represents the module in the inheritance chain. |
-| `ifunc` | Internal FUNCtion. A block implemented in C. |
-| `iseq` | Instruction Sequence.  Usually "iseq" in the C code will refer to an `rb_iseq_t` object that holds a reference to the actual instruction sequences which are executed by the VM. The object also holds information about the code, like the method name associated with the code. |
-| `insn` | Instruction. Refers to a YARV instruction. |
-| `insns` | Instructions. Usually an array of YARV instructions. |
-| `ivar` | Instance Variable. Refers to a Ruby instance variable like `@foo` |
-| `imemo` | Internal Memo.  A tagged struct whose memory is managed by Ruby's GC, but contains internal information and isn't meant to be exposed to Ruby programs. Contains various information depending on the type.  See the `imemo_type` enum for different types. |
-| JIT | Just In Time compiler |
-| `lep` | Local Environment Pointer. An `ep` which is tagged `VM_ENV_FLAG_LOCAL`. Usually this is the `ep` of a method (rather than a block, whose `ep` isn't "local") |
-| `local` | Local. Refers to a local variable. |
-| `me` | Method Entry. Refers to an `rb_method_entry_t` struct, the internal representation of a Ruby method.
-| MRI | Matz's Ruby Implementation |
-| `pc` | Program Counter. Usually the instruction that will be executed _next_ by the VM. Pointed to by the `cfp` and incremented by the VM |
-| `sp` | Stack Pointer. The top of the stack. The VM executes instructions in the `iseq` and instructions will push and pop values on the stack. The VM updates the `sp` on the `cfp` to point at the top of the stack|
-| `svar` | Special Variable. Refers to special local variables like `$~` and `$_`. See the `getspecial` instruction in `insns.def` |
-| `VALUE` | VALUE is a pointer to a ruby object from the Ruby C code. |
-| VM   | Virtual Machine. In MRI's case YARV (Yet Another Ruby VM)
-| WB | Write Barrier.  To do with GC write barriers |
-| WC | Wild Card. As seen in instructions like `getlocal_WC_0`.  It means this instruction takes a "wild card" for the parameter (in this case an index for a local) |
-| YARV | Yet Another Ruby VM.  The virtual machine that CRuby uses |
-| ZOMBIE | A zombie object. An object that has a finalizer which hasn't been executed yet. The object has been collected, so is "dead", but the finalizer hasn't run yet so it's still somewhat alive. |

-# 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_md.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/"
-```

-[these instructions](https://www.ruby-lang.org/en/security/).
-
-## Reporting bugs
-
-If you've encountered a bug in Ruby, please report it to the Redmine issue
-tracker available at [bugs.ruby-lang.org](https://bugs.ruby-lang.org/), by
-following these steps:
-
-* Check if anyone has already reported your issue by
-  searching [the Redmine issue tracker](https://bugs.ruby-lang.org/projects/ruby-master/issues).
-* If you haven't already,
-  [sign up for an account](https://bugs.ruby-lang.org/account/register) on the
-  Redmine issue tracker.
-* If you can't find a ticket addressing your issue, please [create a new issue](https://bugs.ruby-lang.org/projects/ruby-master/issues/new). You will need to fill in the subject, description and Ruby version.
-
-    * Ensure the issue exists on Ruby master by trying to replicate your bug on
-      the head of master (see ["making changes to Ruby"](making_changes_to_ruby.md)).
-    * Write a concise subject and briefly describe your problem in the description section. If
-      your issue affects [a released version of Ruby](#label-Backport+requests), please say so.
-    * Fill in the Ruby version you're using when experiencing this issue
-      (the output of running `ruby -v`).
-    * Attach any logs or reproducible programs to provide additional information.
-      Any scripts should be as small as possible.
-* If the ticket doesn't have any replies after 10 days, you can send a
-  reminder.
-* 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=TestAlias#test_alias_with_zsuper_method"
-    ```
-
-    To run these specs with logs, we can use:
-
-    ```
-    make test-all TESTS=-v
-    ```
-
-    We can display the help of the `TESTS` option:
-
-    ```
-    make test-all TESTS=--help
-    ```
-
-    If we would like to run the `test/`, `bootstraptest/` and `spec/` test suites (the `spec/` is explained in a later section), 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 `SPECOPTS` to specify the directory:
-
-    ```
-    make test-spec SPECOPTS=spec/ruby/core/array
-    ```
-
-    To run a specific file, we can also use `SPECOPTS` to specify the file:
-
-    ```
-    make test-spec SPECOPTS=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 SPECOPTS="../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 SPECOPTS=-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
-    ```
-
-## Troubleshooting
-
-### Running test suites on s390x CPU Architecture
-
-If we see failing tests related to the zlib library on s390x CPU architecture, we can run the test suites with `DFLTCC=0` to pass:
-
-```
-DFLTCC=0 make check
-```
-
-The failures can happen with the zlib library applying the patch [madler/zlib#410](https://github.com/madler/zlib/pull/410) to enable the deflate algorithm producing a different compressed byte stream. We manage this issue at [[ruby-core:114942][Bug #19909]](https://bugs.ruby-lang.org/issues/19909).

-== 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

-# Distribution
-
-This document outlines the expected way to distribute Ruby, with a specific focus on building Ruby packages.
-
-## Getting the Ruby Tarball
-
-### Official Releases
-
-The tarball for official releases is created by the release manager. The release manager uploads the tarball to the [Ruby website](https://www.ruby-lang.org/en/downloads/).
-
-Downstream distributors should use the official release tarballs as part of their build process. This ensures that the tarball is created in a consistent way, and that the tarball is crytographically verified.
-
-### Using the nightly tarball for testing
-
-See the Snapshots section of the [Ruby website](https://www.ruby-lang.org/en/downloads/).
-
-### Building a manual snapshot tarball for testing
-
-This can be useful if the nightly tarball does not have all changes yet.
-
-At Ruby source tree cloned using git:
-```sh-session
-$ ./autogen.sh
-$ ./configure -C
-$ make
-$ make dist
-```
-
-This will create several tarball in the `tmp` directory. The tarball will be named e.g. `ruby-<version>.tar.gz` (several different compression formats will be generated).
-
-## Building the Tarball
-
-See [Building Ruby](contributing/building_ruby.md).
-
-## Updating the Ruby Standard Library
-
-The Ruby standard library is a collection of Ruby files that are included with Ruby. These files are used to provide the basic functionality of Ruby. The standard library is located in the `lib` directory and is distributed as part of the Ruby tarball.
-
-Occasionally, the standard library needs to be updated, for example a security issue might be found in a default gem or standard gem. There are two main ways that Ruby would update this code.
-
-### Releasing an Updated Ruby Gem
-
-Normally, the Ruby gem maintainer will release an updated gem. This gem can be installed alongside the default gem. This allows the user to update the gem without having to update Ruby.
-
-### Releasing a New Ruby Version
-
-If the update is critical, then the Ruby maintainers may decide to release a new version of Ruby. This new version will include the updated standard library.

+= Documentation Guide
+
+This guide discusses recommendations for documenting
+classes, modules, and methods
+in the Ruby core and in the Ruby standard library.
+
+== 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}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Headers].
+- Refer to authoritative and relevant sources using
+  {links}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-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}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Simple+Lists].
+  - Idioms and culture-specific references.
+  - Overuse of headers.
+
+=== \RDoc
+
+Ruby is documented using RDoc.
+For information on \RDoc syntax and features, see the
+{RDoc Markup Reference}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-RDoc+Markup+Reference].
+
+=== Output from <tt>irb</tt>
+
+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 <tt># => ...</tt> in successive lines.
+Alignment may sometimes aid readability:
+
+  a = [1, 2, 3] #=> [1, 2, 3]
+  a.shuffle!    #=> [2, 3, 1]
+  a             #=> [2, 3, 1]
+
+=== Headers
+
+Organize a long discussion with
+{headers}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Headers].
+
+=== Blank Lines
+
+A blank line begins a new paragraph.
+
+A {code block}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Paragraphs+and+Verbatim]
+or {list}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-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.
+
+=== Auto-Linking
+
+In general, \RDoc's auto-linking should not be suppressed.
+For example, we should write +Array+, not <tt>\Array</tt>.
+
+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).
+
+== 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 <tt>What's Here</tt>.
+- Consider listing the parent class and any included modules; consider
+  {links}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Links]
+  to their "What's Here" sections if those exist.
+- List methods as a {labeled list}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Labeled+Lists].
+- Each list entry's label is a method name;
+  if the method has aliases, include those with the "base" method method,
+  and do not list them separately.
+- Check the rendered documentation to determine whether \RDoc has recognized
+  the method and linked to it;  if not, manually insert a
+  {link}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Links].
+- Each entry's description is a 1-line synopsis for the method.
+- Keep the description short.
+- If there are more entries, consider gouping 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:}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-Method+arguments].
+
+Example:
+
+  *  call-seq:
+  *    array.count -> integer
+  *    array.count(obj) -> integer
+  *    array.count {|element| ... } -> integer
+
+When creating the <tt>call-seq</tt>, use the form
+
+  receiver_type.method_name(arguments) {|block_arguments|} -> return_type
+
+Omit the parentheses for cases where the method does not accept arguments,
+and omit the block for cases where a block is not accepted.
+
+In the cases where method can return multiple different types, separate the
+types with "or".  If the method can return any type, use "object".  If the
+method returns the receiver, use "self".
+
+In cases where the method accepts optional arguments, use a <tt>call-seq</tt>
+with an optional argument if the method has the same behavior when an argument
+is omitted as when the argument is passed with the default value.  For example,
+use:
+
+  *     obj.respond_to?(symbol, include_all=false) -> true or false
+
+Instead of:
+
+  *     obj.respond_to?(symbol) -> true or false
+  *     obj.respond_to?(symbol, include_all) -> true or false
+
+However, as shown above for <tt>Array#count</tt>, use separate lines if the
+behavior is different if the argument is omitted.
+
+Omit aliases from the call-seq, but mention them near the end (see below).
+
+
+A +call-seq+ block should have <tt>{|x| ... }</tt>, not <tt>{|x| block }</tt> or <tt>{|x| code }</tt>.
+
+A +call-seq+ output should:
+
+- Have +self+, not +receiver+ or +array+.
+- Begin with +new_+ if and only if the output object is a new instance
+  of the receiver's class, to emphasize that the output object is not +self+.
+
+=== 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 <tt>Array#count</tt>, 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}[https://docs.ruby-lang.org/en/master/RDoc/Markup.html#class-RDoc::Markup-label-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,
+pick the three you think are most important and list those three.
+
+=== 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.

-= 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 {Script Encoding}[rdoc-ref:encodings.rdoc@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 {Script Encoding}[rdoc-ref:encodings.rdoc@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 (Script Encoding)[rdoc-ref:encodings.rdoc@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"

-
-In the case where your struct refers to Ruby objects that are simple values,

-

-You must define a static list of VALUE pointers to the offsets within your

-this reference list. The reference list must end with +RUBY_END_REFS+.

-Some Macros have been provided to make edge referencing easier:
-
-* <code>RUBY_TYPED_DECL_MARKING</code> =A flag that can be set on the +ruby_data_type_t+ to indicate that references are being declared as edges.

-
-* <code>RUBY_REF_END</code> - The end mark of the references list.

-= 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:

+# Ruby Hacking Guide
+
+This document gives some helpful instructions which should make your experience as a Ruby core developer easier.
+
+## Setup
+
+### Make
+
+It's common to want to compile things as quickly as possible. Ensuring `make` has 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)"
+```
+
+## Configure Ruby
+
+It's generally advisable to use a build directory.
+
+``` shell
+./autogen.sh
+mkdir build
+cd build
+../configure --prefix $HOME/.rubies/ruby-head
+make install
+```
+
+### Without Documentation
+
+If you are frequently building Ruby, this will reduce the time it takes to `make install`.
+
+``` shell
+../configure --disable-install-doc
+```
+
+## Running Ruby
+
+### Run Local Test Script
+
+You can create a file in the Ruby source root called `test.rb`. You can build `miniruby` and execute this script:
+
+``` shell
+make run
+```
+
+If you want more of the standard library, you can use `runruby` instead of `run`.
+
+### Run Bootstrap Tests
+
+There are a set of tests in `bootstraptest/` which cover most basic features of the core Ruby language.
+
+``` shell
+make test
+```
+
+### Run Extensive Tests
+
+There are extensive tests in `test/` which cover a wide range of features of the Ruby core language.
+
+``` shell
+make test-all
+```
+
+You can run specific tests by specifying their path:
+
+``` shell
+make test-all TESTS=../test/fiber/test_io.rb
+```
+
+### Run RubySpec Tests
+
+RubySpec is a project to write a complete, executable specification for the Ruby programming language.
+
+``` shell
+make test-all test-rubyspec
+```

-# 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]](https://blade.ruby-lang.org/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.

+= 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.

+# How to use "configure" and "make" commands for Ruby
+
+This is for developers of Ruby.
+If you are a user of Ruby, please see README.md.
+
+## In-place build
+
+```
+$ ./autogen.sh
+$ ./configure --prefix=$PWD/local
+$ make
+$ make install
+$ ./local/bin/ruby -e 'puts "Hello"'
+Hello
+```
+
+## Out-of-place build
+
+```
+$ ./autogen.sh
+$ mkdir ../ruby-build
+$ cd ../ruby-build
+$ ../ruby-src/configure --prefix=$PWD/local
+$ make
+$ make install
+$ ./local/bin/ruby -e 'puts "Hello"'
+Hello
+```
+
+## How to run the whole test suite
+
+```
+$ make check
+```
+
+It runs (about) three test suites:

+
+## 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
+

-\Module \Math provides methods for basic trigonometric,
-logarithmic, and transcendental functions, and for extracting roots.
-
-You can write its constants and method calls thus:
-
-  Math::PI      # => 3.141592653589793
-  Math::E       # => 2.718281828459045
-  Math.sin(0.0) # => 0.0
-  Math.cos(0.0) # => 1.0
-
-If you include module \Math, you can write simpler forms:
-
-  include Math
-  PI       # => 3.141592653589793
-  E        # => 2.718281828459045
-  sin(0.0) # => 0.0
-  cos(0.0) # => 1.0
-
-For simplicity, the examples here assume:
-
-  include Math
-  INFINITY = Float::INFINITY
-
-The domains and ranges for the methods
-are denoted by open or closed intervals,
-using, respectively, parentheses or square brackets:
-
-- An open interval does not include the endpoints:
-
-    (-INFINITY, INFINITY)
-
-- A closed interval includes the endpoints:
-
-    [-1.0, 1.0]
-
-- A half-open interval includes one endpoint, but not the other:
-
-   [1.0, INFINITY)
-
-Many values returned by \Math methods are numerical approximations.
-This is because many such values are, in mathematics,
-of infinite precision, while in numerical computation
-the precision is finite.
-
-Thus, in mathematics, <i>cos(Ï€/2)</i> is exactly zero,
-but in our computation <tt>cos(PI/2)</tt> is a number very close to zero:
-
-  cos(PI/2) # => 6.123031769111886e-17
-
-For very large and very small returned values,
-we have added formatted numbers for clarity:
-
-  tan(PI/2)  # => 1.633123935319537e+16   # 16331239353195370.0
-  tan(PI)    # => -1.2246467991473532e-16 # -0.0000000000000001
-
-See class Float for the constants
-that affect Ruby's floating-point arithmetic.

-= 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]
-

-
-    [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].

-
-\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]

-Each string directive specifies the packing or unpacking
-for one byte in the input or output string.

-=== Binary \String Directives
-
-- <tt>'A'</tt> - Arbitrary binary string (space padded; count is width);
-  +nil+ is treated as the empty string:

-# \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 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]:

-#   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].

-# - {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:

-#     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.

-#
-# ==== 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.

-#
-# ==== 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.
-#
-#   - For method definitions in C code, it must be placed before the
-#     implementation:
-#
-#         /* :nodoc: */
-#         static VALUE
-#         some_method(VALUE self)
-#         {
-#             return self;
-#         }
-#
-#     Note that this directive has <em>no effect at all</em> at method
-#     definition places.  E.g.,
-#
-#         /* :nodoc: */
-#         rb_define_method(cMyClass, "do_something", something_func, 0);
-#
-#     The above comment is just a comment and has nothing to do with \RDoc.
-#     Therefore, +do_something+ method will be reported as "undocumented"
-#     unless that method or function is documented elsewhere.
-#
-#   - For constant definitions in C code, this directive <em>can not work</em>
-#     because there is no "implementation" place for constants.
-#
-# - <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>:stopdoc:</tt>,
-# and <tt>:enddoc:</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:
-#
-# - More typeface markup:
-#   italic, bold, monofont.
-#
-# ====== Italic
-#
-# Text may be marked as italic via HTML tag <tt><i></tt> or <tt><em></tt>.

-# ==== 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.

-#
-# [Multi-Word Text Link]
-#

-#     {GitHub home page}[https://github.com].
-#
-# [<tt>rdoc-ref</tt> Scheme]
-#
-#   A link with the <tt>rdoc-ref:</tt> scheme links to the referenced item,

-#   The referenced item may be a class, module, method, file, etc.
-#
-#   - Class: <tt>Alias[rdoc-ref:RDoc::Alias]</tt> links to Alias[rdoc-ref:RDoc::Alias].
-#   - Module: <tt>RDoc[rdoc-ref:RDoc]</tt> links to RDoc[rdoc-ref:RDoc].
-#   - Method: <tt>foo[rdoc-ref:RDoc::Markup::ToHtml#handle_regexp_RDOCLINK]</tt>

-#   from the resulting text.
-#
-#   - <tt>Nosuch[rdoc-ref:RDoc::Nosuch]</tt> is rendered as
-#     Nosuch[rdoc-ref:RDoc::Nosuch].
-#
-#
-# [<tt>rdoc-label</tt> Scheme]
-#
-#   [Simple]
-#
-#     You can specify a link target using this form,
-#     where the second part cites the id of an HTML element.
-#
-#     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>.
-#
-# Rendered HTML:
-#
-# >>>
-#   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>.
-#
-# 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 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.

+
+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.
+
+== <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 �京都")
+        #=> #<MatchData " �京都">
+
+Arbitrary Ruby expressions can be embedded into patterns with the
+<tt>#{...}</tt> construct.
+
+    place = "�京都"
+    /#{place}/.match("Go to �京都")
+        #=> #<MatchData "�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
+

+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> - Uses an positive lookbehind of the content preceding
+  <tt>\K</tt> in the regexp.  For example, the following two regexps are
+  almost equivalent:
+
+      /ab\Kc/
+      /(?<=ab)c/
+
+  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
+
+== 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)
+
+== Special 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

-# Face
-
-With the `Reline::Face` class, you can modify the text color and text decorations in your terminal emulator.
-This is primarily used to customize the appearance of the method completion dialog in IRB.
-
-## Usage
-
-### ex: Change the background color of the completion dialog cyan to blue
-
-```ruby
-Reline::Face.config(:completion_dialog) do |conf|
-  conf.define :default, foreground: :white, background: :blue
-  #                                                     ^^^^^ `:cyan` by default
-  conf.define :enhanced, foreground: :white, background: :magenta
-  conf.define :scrollbar, foreground: :white, background: :blue
-end
-```
-
-If you provide the above code to an IRB session in some way, you can apply the configuration.
-It's generally done by writing it in `.irbrc`.
-
-Regarding `.irbrc`, please refer to the following link: [https://docs.ruby-lang.org/en/master/IRB.html](https://docs.ruby-lang.org/en/master/IRB.html)
-
-## Available parameters
-
-`Reline::Face` internally creates SGR (Select Graphic Rendition) code according to the block parameter of `Reline::Face.config` method.
-
-| Key         | Value             | SGR Code (numeric part following "\e[")|

-      # Array
-      conf.define :default, style: [:bold, :negative]
-    ```
-- The availability of specific SGR codes depends on your terminal emulator
-- You can specify a hex color code to `:foreground` and `:background` color like `foreground: "#FF1020"`. Its availability also depends on your terminal emulator
-
-## Debugging
-
-You can see the current Face configuration by `Reline::Face.configs` method
-
-Example:
-
-```ruby
-irb(main):001:0> Reline::Face.configs
-=>
-{:default=>
-  {:default=>{:style=>:reset, :escape_sequence=>"\e[0m"},
-   :enhanced=>{:style=>:reset, :escape_sequence=>"\e[0m"},
-   :scrollbar=>{:style=>:reset, :escape_sequence=>"\e[0m"}},
- :completion_dialog=>
-  {:default=>{:foreground=>:white, :background=>:cyan, :escape_sequence=>"\e[0m\e[37;46m"},
-   :enhanced=>{:foreground=>:white, :background=>:magenta, :escape_sequence=>"\e[0m\e[37;45m"},
-   :scrollbar=>{:foreground=>:white, :background=>:cyan, :escape_sequence=>"\e[0m\e[37;46m"}}}
-```
-
-## 256-Color and TrueColor
-
-Reline will automatically detect if your terminal emulator supports truecolor with `ENV['COLORTERM] in 'truecolor' | '24bit'`. When this env is not set, Reline will fallback to 256-color.
-If your terminal emulator supports truecolor but does not set COLORTERM env, add this line to `.irbrc`.
-```ruby
-Reline::Face.force_truecolor
-```

-# RJIT: Ruby JIT
-
-This document has some tips that might be useful when you work on RJIT.
-
-## Project purpose
-
-This project is for experimental purposes.
-For production deployment, consider using YJIT instead.
-
-## Supported platforms
-
-The following platforms are assumed to work. `linux-x86_64` is tested on CI.
-
-* OS: Linux, macOS, BSD
-* Arch: x86\_64
-
-## configure
-### --enable-rjit
-
-On supported platforms, `--enable-rjit` is set by default. You usually don't need to specify this.
-You may still manually pass `--enable-rjit` to try RJIT on unsupported platforms.
-
-### --enable-rjit=dev
-
-It enables `--rjit-dump-disasm` if libcapstone is available.
-
-## make
-### rjit-bindgen
-
-If you see an "RJIT bindgen" GitHub Actions failure, please commit the `git diff` shown on the failed job.
-
-For doing the same thing locally, run `make rjit-bindgen` after installing libclang.
-macOS seems to have libclang by default. On Ubuntu, you can install it with `apt install libclang1`.
-
-## ruby
-### --rjit-stats
-
-This prints RJIT stats at exit.
-
-### --rjit-dump-disasm
-
-This dumps all JIT code. You need to install libcapstone before configure and use `--enable-rjit=dev` on configure.
-
-* Ubuntu: `sudo apt-get install -y libcapstone-dev`
-* macOS: `brew install capstone`

-= Formats for Dates and Times
-
-Several Ruby time-related classes have instance method +strftime+,
-which returns a formatted string representing all or part of a date or time:
-
-- Date#strftime.
-- DateTime#strftime.
-- Time#strftime.
-
-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:
-
-    Time.new(10).strftime('%_Y') # => "  10"
-
-- <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('%^p') # => "AM"
-    Time.now.strftime('%#p') # => "am"
-
-=== Timezone Flags
-
-- <tt>:</tt> - Put timezone as colon-separated hours and minutes:
-
-    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"
-  Time.new(2002, 12).strftime('%B')   # => "December" # No width specifier.
-  Time.new(2002, 12).strftime('%10B') # => "  December"
-  Time.new(2002, 12).strftime('%3B')  # => "December" # Ignored if too small.
-
-= 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"
-  # Return new date parsed from HTTP-formatted string.
-  Date.httpdate(httpdate)  # => #<Date: 2001-02-03>
-  # Return hash parsed from HTTP-formatted string.
-  Date._httpdate(httpdate)
-  # => {: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 3339}[https://datatracker.ietf.org/doc/html/rfc3339]:

-  # => {:year=>2001, :mon=>2, :mday=>3, :hour=>0, :min=>0, :sec=>0, :zone=>"+00:00", :offset=>0}
-
-== 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>]:
-
-  d = Date.new(2001, 2, 3) # => #<Date: 2001-02-03>

-  # => {: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}

-== throw/catch
-
-+throw+ and +catch+ are used to implement non-local control flow in Ruby. They
-operate similarly to exceptions, allowing control to pass directly from the
-place where +throw+ is called to the place where the matching +catch+ is
-called. The main difference between +throw+/+catch+ and the use of exceptions
-is that +throw+/+catch+ are designed for expected non-local control flow,
-while exceptions are designed for exceptional control flow situations, such
-as handling unexpected errors.
-
-When using +throw+, you provide 1-2 arguments.  The first argument is the
-value for the matching +catch+.  The second argument is optional (defaults to
-+nil+), and will be the value that +catch+ returns if there is a matching
-+throw+ inside the +catch+ block.  If no matching +throw+ method is called
-inside a +catch+ block, the +catch+ method returns the return value of the
-block passed to it.

-This prints:
-
-  test baz another string
-
-What operators are available is dependent on the implementing class.
-
-== Operator Behavior
-
-How a class behaves to a given operator is specific to that class, since
-operators are method implementations.
-
-When using an operator, it's the expression on the left-hand side of the
-operation that specifies the behavior.
-
-  'a' * 3         #=> "aaa"
-  3 * 'a'         # TypeError: String can't be coerced into Integer
-
-== Logical Operators
-
-Logical operators are not methods, and therefor cannot be
-redefined/overloaded. They are tokenized at a lower level.
-
-Short-circuit logical operators (<code>&&</code>, <code>||</code>,
-<code>and</code>, and <code>or</code>) do not always result in a boolean value.
-Similar to blocks, it's the last evaluated expression that defines the result
-of the operation.
-
-=== <code>&&</code>, <code>and</code>
-
-Both <code>&&</code>/<code>and</code> operators provide short-circuiting by executing each
-side of the operator, left to right, and stopping at the first occurrence of a
-falsey expression. The expression that defines the result is the last one
-executed, whether it be the final expression, or the first occurrence of a falsey
-expression.
-
-Some examples:
-
-  true && 9 && "string"                       #=> "string"
-  (1 + 2) && nil && "string"                  #=> nil
-  (a = 1) && (b = false) && (c = "string")    #=> false
-
-  puts a                                      #=> 1
-  puts b                                      #=> false
-  puts c                                      #=> nil
-
-In this last example, <code>c</code> was initialized, but not defined.
-
-=== <code>||</code>, <code>or</code>
-
-The means by which <code>||</code>/<code>or</code> short-circuits, is to return the result of
-the first expression that is truthy.
-
-Some examples:
-
-  (1 + 2) || true || "string"                 #=> 3
-  false || nil || "string"                    #=> "string"

+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!

+  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.

-# Windows
-
-Ruby supports a few native build platforms for Windows.
-
-* mswin: Build using Microsoft Visual C++ compiler with vcruntimeXXX.dll
-* mingw-msvcrt: Build using compiler for Mingw with msvcrtXX.dll
-* mingw-ucrt: Build using compiler for Mingw with Windows Universal CRT
-
-## Building Ruby using Mingw with UCRT
-
-The easiest build environment is just a standard [RubyInstaller-Devkit]
-installation and [git-for-windows]. You might like to use [VSCode] as an
-editor.
-
-### Build examples
-
-Ruby core development can be done either in Windows `cmd` like:
-
-```
-ridk enable ucrt64
-
-pacman -S --needed %MINGW_PACKAGE_PREFIX%-openssl %MINGW_PACKAGE_PREFIX%-libyaml %MINGW_PACKAGE_PREFIX%-libffi
-
-cd c:\
-mkdir work
-cd work
-git clone https://github.com/ruby/ruby
-
-cd c:\work\ruby
-sh autogen.sh
-sh configure  -C --disable-install-doc
-make
-```
-
-or in MSYS2 `bash` like:
-
-```
-ridk enable ucrt64
-bash
-
-pacman -S --needed $MINGW_PACKAGE_PREFIX-openssl $MINGW_PACKAGE_PREFIX-libyaml $MINGW_PACKAGE_PREFIX-libffi
-
-cd /c/
-mkdir work
-cd work
-git clone https://github.com/ruby/ruby
-cd ruby
-
-./autogen.sh
-./configure -C --disable-install-doc
-make
-```

-
-## Building Ruby using Visual C++
-
-### Requirement
-
-1.  Windows 7 or later.
-
-2.  Visual C++ 12.0 (2013) or later.
-
-    **Note** if you want to build x64 version, use native compiler for
-    x64.
-
-3.  Please set environment variable `INCLUDE`, `LIB`, `PATH`
-    to run required commands properly from the command line.
-
-    **Note** building ruby requires following commands.
-
-    * nmake
-    * cl
-    * ml
-    * lib
-    * dumpbin
-
-4.  If you want to build from GIT source, following commands are required.
-    * patch
-    * sed
-    * ruby 2.0 or later
-
-    You can use [scoop](https://scoop.sh/) to install them like:
-
-    ```
-    scoop install git ruby sed patch
-    ```
-
-5. You need to install required libraries using [vcpkg](https://vcpkg.io/) like:
-
-    ```
-    vcpkg --triplet x64-windows install openssl libffi libyaml zlib
-    ```
-
-6.  Enable Command Extension of your command line.  It's the default behavior
-    of `cmd.exe`.  If you want to enable it explicitly, run `cmd.exe` with
-    `/E:ON` option.
-
-### How to compile and install
-
-1.  Execute `win32\configure.bat` on your build directory.
-    You can specify the target platform as an argument.
-    For example, run `configure --target=i686-mswin32`
-    You can also specify the install directory.
-    For example, run `configure --prefix=<install_directory>`
-    Default of the install directory is `/usr` .
-    The default _PLATFORM_ is `i386-mswin32_`_MSRTVERSION_ on 32-bit
-    platforms, or `x64-mswin64_`_MSRTVERSION_ on x64 platforms.
-    _MSRTVERSION_ is the 2- or 3-digits version of the Microsoft
-    Runtime Library.
-
-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.  You need specify vcpkg directory to use `--with-opt-dir`
-    option like `configure --with-opt-dir=C:\vcpkg\installed\x64-windows`
-
-4.  Run `nmake up` if you are building from GIT source.
-
-5.  Run `nmake`
-
-6.  Run `nmake check`
-
-7.  Run `nmake install`
-
-### Build examples
-
-* Build on the ruby source directory.
-
-    ```
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-    ```
-
-    ```
-    C:
-    cd \ruby
-    win32\configure --prefix=/usr/local
-    nmake
-    nmake check
-    nmake install
-    ```
-
-* Build on the relative directory from the ruby source directory.
-
-    ```
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby\mswin32
-    install directory:      C:\usr\local
-    ```
-
-    ```
-    C:
-    cd \ruby
-    mkdir mswin32
-    cd mswin32
-    ..\win32\configure --prefix=/usr/local
-    nmake
-    nmake check
-    nmake install
-    ```
-
-* Build on the different drive.
-
-    ```
-    ruby source directory:  C:\src\ruby
-    build directory:        D:\build\ruby
-    install directory:      C:\usr\local
-    ```
-
-    ```
-    D:
-    cd D:\build\ruby
-    C:\src\ruby\win32\configure --prefix=/usr/local
-    nmake
-    nmake check
-    nmake install DESTDIR=C:
-    ```
-
-* Build x64 version (requires native x64 VC++ compiler)
-
-    ```
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-    ```
-
-    ```
-    C:
-    cd \ruby
-    win32\configure --prefix=/usr/local --target=x64-mswin64
-    nmake
-    nmake check
-    nmake install
-    ```
-
-### Bugs
-
-You can **NOT** use a path name that contains any white space characters
-as the ruby source directory, this restriction comes from the behavior
-of `!INCLUDE` directives of `NMAKE`.
-
-You can build ruby in any directory including the source directory,
-except `win32` directory in the source directory.
-This is restriction originating in the path search method of `NMAKE`.
-
-## 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, you can use
-anything you like. You will be able to find many images by search engines.
-For example, followings are made from [Ruby logo kit]:
-
-* Small [favicon] in the official site
-
-* [vit-ruby.ico] or [icon itself]
-
-[Ruby logo kit]: https://cache.ruby-lang.org/pub/misc/logo/ruby-logo-kit.zip
-[favicon]: https://www.ruby-lang.org/favicon.ico
-[vit-ruby.ico]: http://ruby.morphball.net/vit-ruby-ico_en.html

 YJIT - Yet Another Ruby JIT
 ===========================
 
+**DISCLAIMER: Please note that this project is experimental. It is very much a work in progress, it may cause your software to crash, and current performance results will vary widely, especially on larger applications.**
+
 YJIT is a lightweight, minimalistic Ruby JIT built inside CRuby.
-It lazily compiles code using a Basic Block Versioning (BBV) architecture.
-YJIT is currently supported for macOS, Linux and BSD on x86-64 and arm64/aarch64 CPUs.
+It lazily compiles code using a Basic Block Versioning (BBV) architecture. The target use case is that of servers running
+Ruby on Rails, an area where MJIT has not yet managed to deliver speedups.
+To simplify development, we currently support only macOS and Linux on x86-64, but an ARM64 backend
+is part of future plans.
 This project is open source and falls under the same license as CRuby.

 ## Current Limitations
 
-YJIT may not be suitable for certain applications. It currently only supports macOS, Linux and BSD 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).
+YJIT is a work in progress and as such may not yet be mature enough for mission-critical software. Below is a list of known limitations, all of which we plan to eventually address:
 
-## Installation
+- No garbage collection for generated code.
+- Currently supports only macOS and Linux.
+- Currently supports only x86-64 CPUs.
 
-### Requirements
+Because there is no GC for generated code yet, your software could run out of executable memory if it is large enough. You can change how much executable memory is allocated using [YJIT's command-line options](https://github.com/Shopify/yjit#command-line-options).
 
-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).
+## Installation
 
-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.
+Current YJIT versions are installed by default with CRuby. Make sure to specify the "--yjit" command line option to enable it at runtime.

-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).
+The YJIT `ruby` binary can be built with either GCC or Clang. For development, we recommend enabling debug symbols so that assertions are enabled as this makes debugging easier. Enabling debug mode will also make it possible for you to disassemble code generated by YJIT. However, this causes a performance hit. For maximum performance, compile with GCC, without the `DRUBY_DEBUG` or `YJIT_STATS` build options. More detailed build instructions are provided in the [Ruby README](https://github.com/ruby/ruby#how-to-compile-and-install).
+To support disassembly of the generated code, `libcapstone` is also required (`brew install capstone` on MacOS, `sudo apt-get install -y libcapstone-dev` on Ubuntu/Debian and `sudo dnf -y install capstone-devel` on Fedora).

 ## Usage
@@ -147,329 +110,124 @@ make -j test-all
 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-exec-mem-size=N`: size of the executable memory block to allocate, in MiB (default 48 MiB)
-- `--yjit-call-threshold=N`: number of calls after which YJIT begins to compile a function.
-  It defaults to 30, and it's then increased to 120 when the number of ISEQs in the process reaches 40,000.
-- `--yjit-cold-threshold=N`: number of global calls after which an ISEQ is considered cold and not
-  compiled, lower values mean less code is compiled (default 200K)
-- `--yjit-stats`: print statistics after the execution of a program (incurs a run-time cost)
-- `--yjit-stats=quiet`: gather statistics while running a program but don't print them. Stats are accessible through `RubyVM::YJIT.runtime_stats`. (incurs a run-time cost)
-- `--yjit-disable`: disable YJIT despite other `--yjit*` flags for lazily enabling it with `RubyVM::YJIT.enable`
-- `--yjit-code-gc`: enable code GC (disabled by default as of Ruby 3.3).
-  It will cause all machine code to be discarded when the executable memory size limit is hit, meaning JIT compilation will then start over.
-  This can allow you to use a lower executable memory size limit, but may cause a slight drop in performance when the limit is hit.
-- `--yjit-perf`: enable frame pointers and profiling with the `perf` tool
-- `--yjit-trace-exits`: produce a Marshal dump of backtraces from specific exits. Automatically enables `--yjit-stats`
-- `--yjit-trace-exits-sample-rate=N`: trace exit locations only every Nth occurrence
-
-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.
-
-You can also enable YJIT at run-time using `RubyVM::YJIT.enable`. This can allow you to enable YJIT after your application is done
-booting, which makes it possible to avoid compiling any initialization code.
-
-You can verify that YJIT is enabled using `RubyVM::YJIT.enabled?` or by checking that `ruby --yjit -v` includes the string `+YJIT`:
-
-```sh
-ruby --yjit -v
-ruby 3.3.0dev (2023-01-31T15:11:10Z master 2a0bf269c9) +YJIT dev [x86_64-darwin22]
-
-ruby --yjit -e "p RubyVM::YJIT.enabled?"
-true
-
-ruby -e "RubyVM::YJIT.enable; p RubyVM::YJIT.enabled?"
-true
-```
+- `--disable-yjit`: turn off YJIT (enabled by default)
+- `--yjit-stats`: produce statistics after the execution of a program (must compile with `cppflags=-DRUBY_DEBUG` to use this)
+- `--yjit-exec-mem-size=N`: size of the executable memory block to allocate (default 256 MiB)
+- `--yjit-call-threshold=N`: number of calls after which YJIT begins to compile a function (default 2)
+- `--yjit-max-versions=N`: maximum number of versions to generate per basic block (default 4)
+- `--yjit-greedy-versioning`: greedy versioning mode (disabled by default, may increase code size)
 
 ### 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.
-
-## 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 stops compiling new code. Increasing the executable memory size means more code
-can be optimized by YJIT, at the cost of more memory usage.
-
-If you start Ruby with `--yjit-stats`, e.g. using an environment variable `RUBYOPT=--yjit-stats`,
-`RubyVM::YJIT.runtime_stats[:ratio_in_yjit]` shows the ratio of YJIT-executed instructions in %.
-Ideally, `ratio_in_yjit` should be as large as 99%, and increasing `--yjit-exec-mem-size` often
-helps improving `ratio_in_yjit`.
-
-### 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.
+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.
 
-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.
+### Performance Tips
 
-## Reducing YJIT Memory Usage
+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, but you can profile your code using a tool such as [stackprof](https://github.com/tmm1/stackprof) and refactor the specific methods that make up the largest fractions of the execution time.
 
-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.
-
-### Decreasing --yjit-exec-mem-size
-
-The `--yjit-exec-mem-size` option 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 3.3. You should multiply that by the number
-of worker processes to estimate the worst case memory overhead.
-
-`--yjit-exec-mem-size=48` is the default since Ruby 3.3.1,
-but smaller values like 32 MiB might make sense for your application.
-While doing so, you may want to monitor `RubyVM::YJIT.runtime_stats[:ratio_in_yjit]` as explained above.
-
-### Enabling YJIT lazily
-
-If you enable YJIT by `--yjit` options or `RUBY_YJIT_ENABLE=1`, YJIT may compile code that is
-used only during the application boot. `RubyVM::YJIT.enable` allows you to enable YJIT from Ruby code,
-and you can call this after your application is initialized, e.g. on Unicorn's `after_fork` hook.
-If you use any YJIT options (`--yjit-*`), YJIT will start at boot by default, but `--yjit-disable`
-allows you to start Ruby with the YJIT-disabled mode while passing YJIT tuning options.
-
-## 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`
+- Use exceptions for error recovery only, not as part of normal control-flow
 - 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
+- Use while loops if you can, instead of `integer.times`
 - Minimize layers of indirection
   - Avoid classes that wrap objects if you can
-  - Avoid methods that just call another method, trivial one-liner methods
+  - Avoid methods that just call another method, trivial one liner methods
+- CRuby method calls are costly. Favor larger methods over smaller 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-stats`, YJIT will track and return performance statistics in `RubyVM::YJIT.runtime_stats`.
-
-```rb
-$ RUBYOPT="--yjit-stats" irb
-irb(main):001:0> RubyVM::YJIT.runtime_stats
-=>
-{:inline_code_size=>340745,
- :outlined_code_size=>297664,
- :all_stats=>true,
- :yjit_insns_count=>1547816,
- :send_callsite_not_simple=>7267,
- :send_kw_splat=>7,
- :send_ivar_set_method=>72,
-...
-```
-
-Some of the counters include:
 
-* :yjit_insns_count - 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.)
-
-Performance counter names are not guaranteed to remain the same between Ruby versions. If you're curious what each counter means,
-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 `RubyVM::YJIT.runtime_stats`.
+You can also compile YJIT in debug mode and 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.

 ### Source Code Organization
 
 The YJIT source code is divided between:
-- `yjit.c`: code YJIT uses to interface with the rest of CRuby
+- `yjit_asm.c`: x86 in-memory assembler we use to generate machine code
+- `yjit_codegen.c`: logic for translating Ruby bytecode to machine code
+- `yjit_core.c`: basic block versioning logic, core structure of YJIT
+- `yjit_iface.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/src/cruby.rs`: C bindings manually exposed to the Rust codebase
-- `yjit/bindgen/src/main.rs`: C bindings exposed to the Rust codebase through bindgen
+- `misc/test_yjit_asm.sh`: script to compile and run the in-memory assembler tests
+- `misc/yjit_asm_tests.c`: tests for the in-memory assembler
 
 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 multiple test suites:
+There are 3 test suites:
 - `make btest` (see `/bootstraptest`)
 - `make test-all`
 - `make test-spec`
 - `make check` runs all of the above
-- `make yjit-smoke-test` runs quick checks to see that YJIT is working correctly
 
 The tests can be run in parallel like this:
 
-```sh
-make -j test-all RUN_OPTS="--yjit-call-threshold=1"
+```
+make -j16 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 $HOME/.cargo by default, and I don't know a good way to change architectures after install
-
-If you use Fish shell you can [read this link](https://tenderlovemaking.com/2022/01/07/homebrew-rosetta-and-ruby.html) for information on making the dev environment easier.
-
-## Profiling with Linux perf
-
-`--yjit-perf` allows you to profile JIT-ed methods along with other native functions using Linux perf.
-When you run Ruby with `perf record`, perf looks up `/tmp/perf-{pid}.map` to resolve symbols in JIT code,
-and this option lets YJIT write method symbols into that file as well as enabling frame pointers.
-
-Here's an example way to use this option with [Firefox Profiler](https://profiler.firefox.com)
-(See also: [Profiling with Linux perf](https://profiler.firefox.com/docs/#/./guide-perf-profiling)):
-
-```bash
-# Compile the interpreter with frame pointers enabled
-./configure --enable-yjit --prefix=$HOME/.rubies/ruby-yjit --disable-install-doc cflags=-fno-omit-frame-pointer
-make -j && make install
-
-# [Optional] Allow running perf without sudo
-echo 0 | sudo tee /proc/sys/kernel/kptr_restrict
-echo -1 | sudo tee /proc/sys/kernel/perf_event_paranoid
-
-# Profile Ruby with --yjit-perf
-cd ../yjit-bench
-perf record --call-graph fp -- ruby --yjit-perf -Iharness-perf benchmarks/liquid-render/benchmark.rb
-
-# View results on Firefox Profiler https://profiler.firefox.com.
-# Create /tmp/test.perf as below and upload it using "Load a profile from file".
-perf script --fields +pid > /tmp/test.perf
+echo "settings set target.x86-disassembly-flavor intel" >> ~/.lldbinit

- * It has a name and, optionally, aliases:
+ * An Encoding instance represents a character encoding usable in Ruby. It is
+ * defined as a constant under the Encoding namespace. It has a name and
+ * optionally, aliases:
+ *
+ *   Encoding::ISO_8859_1.name
+ *   #=> "ISO-8859-1"
+ *
+ *   Encoding::ISO_8859_1.names
+ *   #=> ["ISO-8859-1", "ISO8859-1"]
+ *
+ * Ruby methods dealing with encodings return or accept Encoding instances as
+ * arguments (when a method accepts an Encoding instance as an argument, it
+ * can be passed an Encoding name or alias instead).
+ *
+ *   "some string".encoding
+ *   #=> #<Encoding:UTF-8>
+ *
+ *   string = "some string".encode(Encoding::ISO_8859_1)
+ *   #=> "some string"
+ *   string.encoding
+ *   #=> #<Encoding:ISO-8859-1>
+ *
+ *   "some string".encode "ISO-8859-1"
+ *   #=> "some string"
+ *
+ * Encoding::ASCII_8BIT is a special encoding that is usually used for
+ * a byte string, not a character string. But as the name insists, its
+ * characters in the range of ASCII are considered as ASCII
+ * characters.  This is useful when you use ASCII-8BIT characters with
+ * other ASCII compatible characters.
+ *
+ * == Changing an encoding
+ *
+ * The associated Encoding of a String can be changed in two different ways.
+ *
+ * First, it is possible to set the Encoding of a string to a new Encoding
+ * without changing the internal byte representation of the string, with
+ * String#force_encoding. This is how you can tell Ruby the correct encoding
+ * of a string.
+ *
+ *   string
+ *   #=> "R\xC3\xA9sum\xC3\xA9"
+ *   string.encoding
+ *   #=> #<Encoding:ISO-8859-1>
+ *   string.force_encoding(Encoding::UTF_8)
+ *   #=> "R\u00E9sum\u00E9"
  *
- *   Encoding::US_ASCII.name  # => "US-ASCII"
- *   Encoding::US_ASCII.names # => ["US-ASCII", "ASCII", "ANSI_X3.4-1968", "646"]
+ * Second, it is possible to transcode a string, i.e. translate its internal
+ * byte representation to another encoding. Its associated encoding is also
+ * set to the other encoding. See String#encode for the various forms of
+ * transcoding, and the Encoding::Converter class for additional control over
+ * the transcoding process.
  *
- * A Ruby method that accepts an encoding as an argument will accept:
+ *   string
+ *   #=> "R\u00E9sum\u00E9"
+ *   string.encoding
+ *   #=> #<Encoding:UTF-8>
+ *   string = string.encode!(Encoding::ISO_8859_1)
+ *   #=> "R\xE9sum\xE9"
+ *   string.encoding
+ *   #=> #<Encoding::ISO-8859-1>
  *
- * - An \Encoding object.
- * - The name of an encoding.
- * - An alias for an encoding name.
+ * == Script encoding
  *
- * These are equivalent:
+ * All Ruby script code has an associated Encoding which any String literal
+ * created in the source code will be associated to.
  *
- *   'foo'.encode(Encoding::US_ASCII) # Encoding object.
- *   'foo'.encode('US-ASCII')         # Encoding name.
- *   'foo'.encode('ASCII')            # Encoding alias.
+ * The default script encoding is Encoding::UTF_8 after v2.0, but it
+ * can be changed by a magic comment on the first line of the source
+ * code file (or second line, if there is a shebang line on the
+ * first). The comment must contain the word <code>coding</code> or
+ * <code>encoding</code>, followed by a colon, space and the Encoding
+ * name or alias:
  *
- * For a full discussion of encodings and their uses,
- * see {the Encodings document}[rdoc-ref:encodings.rdoc].
+ *   # encoding: UTF-8
  *
- * Encoding::ASCII_8BIT is a special-purpose encoding that is usually used for
- * a string of bytes, not a string of characters.
- * But as the name indicates, its characters in the ASCII range
- * are considered as ASCII characters.
- * This is useful when you use other ASCII-compatible encodings.
+ *   "some string".encoding
+ *   #=> #<Encoding:UTF-8>
+ *
+ * The <code>__ENCODING__</code> keyword returns the script encoding of the file
+ * which the keyword is written:
+ *
+ *   # encoding: ISO-8859-1
+ *
+ *   __ENCODING__
+ *   #=> #<Encoding:ISO-8859-1>
+ *
+ * <code>ruby -K</code> will change the default locale encoding, but this is
+ * not recommended. Ruby source files should declare its script encoding by a
+ * magic comment even when they only depend on US-ASCII strings or regular
+ * expressions.
+ *
+ * == Locale encoding
+ *
+ * The default encoding of the environment. Usually derived from locale.
+ *
+ * see Encoding.locale_charmap, Encoding.find('locale')
+ *
+ * == Filesystem encoding
+ *
+ * The default encoding of strings from the filesystem of the environment.
+ * This is used for strings of file names or paths.
+ *
+ * see Encoding.find('filesystem')
+ *
+ * == External encoding
+ *
+ * Each IO object has an external encoding which indicates the encoding that
+ * Ruby will use to read its data. By default Ruby sets the external encoding
+ * of an IO object to the default external encoding. The default external
+ * encoding is set by locale encoding or the interpreter <code>-E</code> option.
+ * Encoding.default_external returns the current value of the external
+ * encoding.
+ *
+ *   ENV["LANG"]
+ *   #=> "UTF-8"
+ *   Encoding.default_external
+ *   #=> #<Encoding:UTF-8>
+ *
+ *   $ ruby -E ISO-8859-1 -e "p Encoding.default_external"
+ *   #<Encoding:ISO-8859-1>
+ *
+ *   $ LANG=C ruby -e 'p Encoding.default_external'
+ *   #<Encoding:US-ASCII>
+ *
+ * The default external encoding may also be set through
+ * Encoding.default_external=, but you should not do this as strings created
+ * before and after the change will have inconsistent encodings.  Instead use
+ * <code>ruby -E</code> to invoke ruby with the correct external encoding.
+ *
+ * When you know that the actual encoding of the data of an IO object is not
+ * the default external encoding, you can reset its external encoding with
+ * IO#set_encoding or set it at IO object creation (see IO.new options).
+ *
+ * == Internal encoding
+ *
+ * To process the data of an IO object which has an encoding different
+ * from its external encoding, you can set its internal encoding. Ruby will use
+ * this internal encoding to transcode the data when it is read from the IO
+ * object.
+ *
+ * Conversely, when data is written to the IO object it is transcoded from the
+ * internal encoding to the external encoding of the IO object.
+ *
+ * The internal encoding of an IO object can be set with
+ * IO#set_encoding or at IO object creation (see IO.new options).
+ *
+ * The internal encoding is optional and when not set, the Ruby default
+ * internal encoding is used. If not explicitly set this default internal
+ * encoding is +nil+ meaning that by default, no transcoding occurs.
+ *
+ * The default internal encoding can be set with the interpreter option
+ * <code>-E</code>. Encoding.default_internal returns the current internal
+ * encoding.
+ *
+ *    $ ruby -e 'p Encoding.default_internal'
+ *    nil
+ *
+ *    $ ruby -E ISO-8859-1:UTF-8 -e "p [Encoding.default_external, \
+ *      Encoding.default_internal]"
+ *    [#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>]
+ *
+ * The default internal encoding may also be set through
+ * Encoding.default_internal=, but you should not do this as strings created
+ * before and after the change will have inconsistent encodings.  Instead use
+ * <code>ruby -E</code> to invoke ruby with the correct internal encoding.
+ *
+ * == IO encoding example
+ *
+ * In the following example a UTF-8 encoded string "R\u00E9sum\u00E9" is transcoded for
+ * output to ISO-8859-1 encoding, then read back in and transcoded to UTF-8:
+ *
+ *   string = "R\u00E9sum\u00E9"
+ *
+ *   open("transcoded.txt", "w:ISO-8859-1") do |io|
+ *     io.write(string)
+ *   end
+ *
+ *   puts "raw text:"
+ *   p File.binread("transcoded.txt")
+ *   puts
+ *
+ *   open("transcoded.txt", "r:ISO-8859-1:UTF-8") do |io|
+ *     puts "transcoded text:"
+ *     p io.read
+ *   end
+ *
+ * While writing the file, the internal encoding is not specified as it is
+ * only necessary for reading.  While reading the file both the internal and
+ * external encoding must be specified to obtain the correct result.
+ *
+ *   $ ruby t.rb
+ *   raw text:
+ *   "R\xE9sum\xE9"
+ *
+ *   transcoded text:
+ *   "R\u00E9sum\u00E9"
  *

- *   variable and mutate some ivar of it).
- *
- * Concretely:
- *
- *   Thread.current[:fiber_local] = 1
- *   Fiber[:storage_var] = 1
- *   e = Enumerator.new do |y|
- *     p Thread.current[:fiber_local] # for external iteration: nil, for internal iteration: 1
- *     p Fiber[:storage_var] # => 1, inherited
- *     Fiber[:storage_var] += 1
- *     y << 42
- *   end
- *
- *   p e.next # => 42
- *   p Fiber[:storage_var] # => 1 (it ran in a different Fiber)
+ * Note that enumeration sequence by +next+, +next_values+, +peek+ and
+ * +peek_values+ do not affect other non-external
+ * enumeration methods, unless the underlying iteration method itself has
+ * side-effect, e.g. IO#each_line.
  *
- *   e.each { p _1 }
- *   p Fiber[:storage_var] # => 2 (it ran in the same Fiber/"stack" as the current Fiber)
+ * Moreover, implementation typically uses fibers so performance could be
+ * slower and exception stacktraces different than expected.
  *
- * == Convert External Iteration to Internal Iteration
- *
- * You can use an external iterator to implement an internal iterator as follows:

+ *      %D - Date (%m/%d/%y)
+ *      %F - The ISO 8601 date format (%Y-%m-%d)
+ *      %v - VMS date (%e-%^b-%Y)
+ *      %x - Same as %D
+ *      %X - Same as %T
+ *      %r - 12-hour time (%I:%M:%S %p)
+ *      %R - 24-hour time (%H:%M)
+ *      %T - 24-hour time (%H:%M:%S)
+ *      %+ - date(1) (%a %b %e %H:%M:%S %Z %Y)
+ *
+ * This method is similar to the strftime() function defined in ISO C
+ * and POSIX.
+ * Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z)
+ * are locale dependent in the function.
+ * However, this method is locale independent.
+ * So, the result may differ even if the same format string is used in other
+ * systems such as C.
+ * It is good practice to avoid %x and %X because there are corresponding
+ * locale independent representations, %D and %T.
+ *
+ * Examples:
+ *
+ *    d = DateTime.new(2007,11,19,8,37,48,"-06:00")
+ *				#=> #<DateTime: 2007-11-19T08:37:48-0600 ...>
+ *    d.strftime("Printed on %m/%d/%Y")   #=> "Printed on 11/19/2007"
+ *    d.strftime("at %I:%M%p")            #=> "at 08:37AM"
+ *
+ * Various ISO 8601 formats:
+ *    %Y%m%d           => 20071119                  Calendar date (basic)

+ *      %T - 24-hour time (%H:%M:%S)
+ *      %+ - date(1) (%a %b %e %H:%M:%S %Z %Y)
+ *
+ * This method is similar to the strftime() function defined in ISO C
+ * and POSIX.
+ * Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z)
+ * are locale dependent in the function.
+ * However, this method is locale independent.
+ * So, the result may differ even if the same format string is used in other
+ * systems such as C.
+ * It is good practice to avoid %x and %X because there are corresponding
+ * locale independent representations, %D and %T.
+ *
+ * Examples:
+ *
+ *    d = DateTime.new(2007,11,19,8,37,48,"-06:00")
+ *				#=> #<DateTime: 2007-11-19T08:37:48-0600 ...>
+ *    d.strftime("Printed on %m/%d/%Y")   #=> "Printed on 11/19/2007"
+ *    d.strftime("at %I:%M%p")            #=> "at 08:37AM"
+ *

     /*
-     * \Class \Date provides methods for storing and manipulating
-     * calendar dates.
+     * date and datetime class - Tadayoshi Funaba 1998-2011
+     *
+     * 'date' provides two classes: Date and DateTime.
+     *
+     * == Terms and Definitions
+     *
+     * Some terms and definitions are based on ISO 8601 and JIS X 0301.
      *
-     * Consider using
-     * {class Time}[rdoc-ref:Time]
-     * instead of class \Date if:
+     * === Calendar Date
      *
-     * - You need both dates and times; \Date handles only dates.
-     * - You need only Gregorian dates (and not Julian dates);
-     *   see {Julian and Gregorian Calendars}[rdoc-ref:calendars.rdoc].
+     * The calendar date is a particular day of a calendar year,
+     * identified by its ordinal number within a calendar month within
+     * that year.
      *
-     * A \Date object, once created, is immutable, and cannot be modified.
+     * In those classes, this is so-called "civil".
      *
-     * == Creating a \Date
+     * === Ordinal Date
      *
-     * You can create a date for the current date, using Date.today:
+     * The ordinal date is a particular day of a calendar year identified
+     * by its ordinal number within the year.
      *
-     *   Date.today # => #<Date: 1999-12-31>
+     * In those classes, this is so-called "ordinal".
      *
-     * You can create a specific date from various combinations of arguments:
+     * === Week Date
      *
-     * - Date.new takes integer year, month, and day-of-month:
+     * The week date is a date identified by calendar week and day numbers.
      *
-     *     Date.new(1999, 12, 31) # => #<Date: 1999-12-31>
+     * The calendar week is a seven day period within a calendar year,
+     * starting on a Monday and identified by its ordinal number within
+     * the year; the first calendar week of the year is the one that
+     * includes the first Thursday of that year. In the Gregorian
+     * calendar, this is equivalent to the week which includes January 4.
      *
-     * - Date.ordinal takes integer year and day-of-year:
+     * In those classes, this is so-called "commercial".
      *
-     *     Date.ordinal(1999, 365) # => #<Date: 1999-12-31>
+     * === Julian Day Number
      *
-     * - Date.jd takes integer Julian day:
+     * The Julian day number is in elapsed days since noon (Greenwich Mean
+     * Time) on January 1, 4713 BCE (in the Julian calendar).
      *
-     *     Date.jd(2451544) # => #<Date: 1999-12-31>
+     * In this document, the astronomical Julian day number is the same as
+     * the original Julian day number. And the chronological Julian day
+     * number is a variation of the Julian day number. Its days begin at
+     * midnight on local time.
      *
-     * - Date.commercial takes integer commercial data (year, week, day-of-week):
+     * In this document, when the term "Julian day number" simply appears,
+     * it just refers to "chronological Julian day number", not the
+     * original.
      *
-     *     Date.commercial(1999, 52, 5) # => #<Date: 1999-12-31>
+     * In those classes, those are so-called "ajd" and "jd".
      *
-     * - Date.parse takes a string, which it parses heuristically:
+     * === Modified Julian Day Number
      *
-     *     Date.parse('1999-12-31')    # => #<Date: 1999-12-31>
-     *     Date.parse('31-12-1999')    # => #<Date: 1999-12-31>
-     *     Date.parse('1999-365')      # => #<Date: 1999-12-31>
-     *     Date.parse('1999-W52-5')    # => #<Date: 1999-12-31>
+     * The modified Julian day number is in elapsed days since midnight
+     * (Coordinated Universal Time) on November 17, 1858 CE (in the
+     * Gregorian calendar).
      *
-     * - Date.strptime takes a date string and a format string,
-     *   then parses the date string according to the format string:
+     * In this document, the astronomical modified Julian day number is
+     * the same as the original modified Julian day number. And the
+     * chronological modified Julian day number is a variation of the
+     * modified Julian day number. Its days begin at midnight on local
+     * time.
      *
-     *     Date.strptime('1999-12-31', '%Y-%m-%d')  # => #<Date: 1999-12-31>
-     *     Date.strptime('31-12-1999', '%d-%m-%Y')  # => #<Date: 1999-12-31>
-     *     Date.strptime('1999-365', '%Y-%j')       # => #<Date: 1999-12-31>
-     *     Date.strptime('1999-W52-5', '%G-W%V-%u') # => #<Date: 1999-12-31>
-     *     Date.strptime('1999 52 5', '%Y %U %w')   # => #<Date: 1999-12-31>
-     *     Date.strptime('1999 52 5', '%Y %W %u')   # => #<Date: 1999-12-31>
-     *     Date.strptime('fri31dec99', '%a%d%b%y')  # => #<Date: 1999-12-31>
+     * In this document, when the term "modified Julian day number" simply
+     * appears, it just refers to "chronological modified Julian day
+     * number", not the original.
      *
-     * See also the specialized methods in
-     * {"Specialized Format Strings" in Formats for Dates and Times}[rdoc-ref:strftime_formatting.rdoc@Specialized+Format+Strings]
+     * In those classes, those are so-called "amjd" and "mjd".
+     *
+     * == Date
+     *
+     * A subclass of Object that includes the Comparable module and
+     * easily handles date.
+     *
+     * A Date object is created with Date::new, Date::jd, Date::ordinal,
+     * Date::commercial, Date::parse, Date::strptime, Date::today,
+     * Time#to_date, etc.
+     *
+     *     require 'date'
      *
-     * == Argument +limit+
+     *     Date.new(2001,2,3)
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Date.jd(2451944)
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Date.ordinal(2001,34)
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Date.commercial(2001,5,6)
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Date.parse('2001-02-03')
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Date.strptime('03-02-2001', '%d-%m-%Y')
+     *	    #=> #<Date: 2001-02-03 ...>
+     *     Time.new(2001,2,3).to_date
+     *	    #=> #<Date: 2001-02-03 ...>
      *
-     * Certain singleton methods in \Date that parse string arguments
-     * also take optional keyword argument +limit+,
-     * which can limit the length of the string argument.
+     * All date objects are immutable; hence cannot modify themselves.
      *
-     * When +limit+ is:
+     * The concept of a date object can be represented as a tuple
+     * of the day count, the offset and the day of calendar reform.
      *
-     * - Non-negative:
-     *   raises ArgumentError if the string length is greater than _limit_.
-     * - Other numeric or +nil+: ignores +limit+.
-     * - Other non-numeric: raises TypeError.
+     * The day count denotes the absolute position of a temporal
+     * dimension. The offset is relative adjustment, which determines
+     * decoded local time with the day count. The day of calendar
+     * reform denotes the start day of the new style. The old style
+     * of the West is the Julian calendar which was adopted by
+     * Caesar. The new style is the Gregorian calendar, which is the
+     * current civil calendar of many countries.
+     *
+     * The day count is virtually the astronomical Julian day number.
+     * The offset in this class is usually zero, and cannot be
+     * specified directly.
+     *
+     * A Date object can be created with an optional argument,
+     * the day of calendar reform as a Julian day number, which
+     * should be 2298874 to 2426355 or negative/positive infinity.
+     * The default value is +Date::ITALY+ (2299161=1582-10-15).

- *
- * The behavior of most IO methods is not affected by this flag
- * because they retry system calls to complete their task
- * after EAGAIN and partial read/write.
- * (An exception is IO#syswrite which doesn't retry.)
- *
- * This method can be used to clear non-blocking mode of standard I/O.
- * Since nonblocking methods (read_nonblock, etc.) set non-blocking mode but
- * they doesn't clear it, this method is usable as follows.
- *
- *   END { STDOUT.nonblock = false }
- *   STDOUT.write_nonblock("foo")
- *
- * Since the flag is shared across processes and
- * many non-Ruby commands doesn't expect standard I/O with non-blocking mode,
- * it would be safe to clear the flag before Ruby program exits.
- *
- * For example following Ruby program leaves STDIN/STDOUT/STDER non-blocking mode.
- * (STDIN, STDOUT and STDERR are connected to a terminal.
- * So making one of them nonblocking-mode effects other two.)
- * Thus cat command try to read from standard input and

- *   % ruby -e '
- *   STDOUT.write_nonblock("foo\n")'; cat

-Version 3.2.0
-=============
-
-Compatibility
--------------
-
-* Ruby >= 2.7
-  - Support for Ruby 2.6 has been removed. Note that Ruby 2.6 reached the
-    end-of-life in 2022-04.
-    [[GitHub #639]](https://github.com/ruby/openssl/pull/639)
-* OpenSSL >= 1.0.2 or LibreSSL >= 3.1
-
-Notable changes
----------------
-
-* Add a stub gemspec for JRuby, which depends on the `jruby-openssl` gem.
-  [[GitHub #598]](https://github.com/ruby/openssl/pull/598)
-* Add support for the FIPS module in OpenSSL 3.0/3.1.
-  [[GitHub #608]](https://github.com/ruby/openssl/pull/608)
-* Rework `OpenSSL::PKey` routines for loading DER or PEM encoded keys for better
-  compatibility with OpenSSL 3.0/3.1 with the FIPS module.
-  [[GitHub #615]](https://github.com/ruby/openssl/pull/615)
-  [[GitHub #669]](https://github.com/ruby/openssl/pull/669)
-* Add `OpenSSL::Provider` module for loading and unloading OpenSSL 3 providers.
-  [[GitHub #635]](https://github.com/ruby/openssl/pull/635)
-* Add `OpenSSL::PKey.new_raw_private_key`, `.new_raw_public_key`,
-  `OpenSSL::PKey::PKey#raw_private_key`, and `#raw_public_key` for public key
-  algorithms that use "raw private/public key", such as X25519 and Ed25519.
-  [[GitHub #646]](https://github.com/ruby/openssl/pull/646)
-* Improve OpenSSL error messages to include additional information when
-  it is available in OpenSSL's error queue.
-  [[GitHub #648]](https://github.com/ruby/openssl/pull/648)
-* Change `OpenSSL::SSL::SSLContext#ca_file=` and `#ca_path=` to raise
-  `OpenSSL::SSL::SSLError` instead of printing a warning message.
-  [[GitHub #659]](https://github.com/ruby/openssl/pull/659)
-* Allow `OpenSSL::X509::ExtensionFactory#create_extension` to take OIDs in the
-  dotted-decimal notation.
-  [[GitHub #141]](https://github.com/ruby/openssl/pull/141)
-
-
-Version 3.1.0
-=============
-
-Ruby/OpenSSL 3.1 will be maintained for the lifetime of Ruby 3.2.
-
-Merged bug fixes in 2.2.3 and 3.0.2. Among the new features and changes are:
-
-Notable changes
----------------
-
-* Add `OpenSSL::SSL::SSLContext#ciphersuites=` to allow setting TLS 1.3 cipher
-  suites.
-  [[GitHub #493]](https://github.com/ruby/openssl/pull/493)
-* Add `OpenSSL::SSL::SSLSocket#export_keying_material` for exporting keying
-  material of the session, as defined in RFC 5705.
-  [[GitHub #530]](https://github.com/ruby/openssl/pull/530)
-* Add `OpenSSL::SSL::SSLContext#keylog_cb=` for setting the TLS key logging
-  callback, which is useful for supporting NSS's SSLKEYLOGFILE debugging output.
-  [[GitHub #536]](https://github.com/ruby/openssl/pull/536)
-* Remove the default digest algorithm from `OpenSSL::OCSP::BasicResponse#sign`
-  and `OpenSSL::OCSP::Request#sign`. Omitting the 5th parameter of these
-  methods used to be equivalent of specifying SHA-1. This default value is now
-  removed and we will let the underlying OpenSSL library decide instead.
-  [[GitHub #507]](https://github.com/ruby/openssl/pull/507)
-* Add `OpenSSL::BN#mod_sqrt`.
-  [[GitHub #553]](https://github.com/ruby/openssl/pull/553)
-* Allow calling `OpenSSL::Cipher#update` with an empty string. This was
-  prohibited to workaround an ancient bug in OpenSSL.
-  [[GitHub #568]](https://github.com/ruby/openssl/pull/568)
-* Fix build on platforms without socket support, such as WASI. `OpenSSL::SSL`
-  will not be defined if OpenSSL is compiled with `OPENSSL_NO_SOCK`.
-  [[GitHub #558]](https://github.com/ruby/openssl/pull/558)
-* Improve support for recent LibreSSL versions. This includes HKDF support in
-  LibreSSL 3.6 and Ed25519 support in LibreSSL 3.7.
-
-
-Version 3.0.2
-=============
-
-Merged changes in 2.2.3. Additionally, the following issues are fixed by this
-release.

+/*
+ * Introduction
+ * ************
+ *
+ * The following notes assume that you are familiar with the YAML specification
+ * (http://yaml.org/spec/cvs/current.html).  We mostly follow it, although in
+ * some cases we are less restrictive that it requires.
+ *
+ * The process of transforming a YAML stream into a sequence of events is
+ * divided on two steps: Scanning and Parsing.
+ *
+ * The Scanner transforms the input stream into a sequence of tokens, while the
+ * parser transform the sequence of tokens produced by the Scanner into a
+ * sequence of parsing events.
+ *
+ * The Scanner is rather clever and complicated. The Parser, on the contrary,
+ * is a straightforward implementation of a recursive-descendant parser (or,
+ * LL(1) parser, as it is usually called).
+ *
+ * Actually there are two issues of Scanning that might be called "clever", the
+ * rest is quite straightforward.  The issues are "block collection start" and
+ * "simple keys".  Both issues are explained below in details.
+ *
+ * Here the Scanning step is explained and implemented.  We start with the list
+ * of all the tokens produced by the Scanner together with short descriptions.
+ *
+ * Now, tokens:
+ *
+ *      STREAM-START(encoding)          # The stream start.
+ *      STREAM-END                      # The stream end.
+ *      VERSION-DIRECTIVE(major,minor)  # The '%YAML' directive.
+ *      TAG-DIRECTIVE(handle,prefix)    # The '%TAG' directive.
+ *      DOCUMENT-START                  # '---'
+ *      DOCUMENT-END                    # '...'
+ *      BLOCK-SEQUENCE-START            # Indentation increase denoting a block
+ *      BLOCK-MAPPING-START             # sequence or a block mapping.
+ *      BLOCK-END                       # Indentation decrease.
+ *      FLOW-SEQUENCE-START             # '['
+ *      FLOW-SEQUENCE-END               # ']'
+ *      FLOW-MAPPING-START              # '{'
+ *      FLOW-MAPPING-END                # '}'
+ *      BLOCK-ENTRY                     # '-'
+ *      FLOW-ENTRY                      # ','
+ *      KEY                             # '?' or nothing (simple keys).
+ *      VALUE                           # ':'
+ *      ALIAS(anchor)                   # '*anchor'
+ *      ANCHOR(anchor)                  # '&anchor'
+ *      TAG(handle,suffix)              # '!handle!suffix'
+ *      SCALAR(value,style)             # A scalar.
+ *
+ * The following two tokens are "virtual" tokens denoting the beginning and the
+ * end of the stream:
+ *
+ *      STREAM-START(encoding)
+ *      STREAM-END
+ *
+ * We pass the information about the input stream encoding with the
+ * STREAM-START token.
+ *
+ * The next two tokens are responsible for tags:
+ *
+ *      VERSION-DIRECTIVE(major,minor)
+ *      TAG-DIRECTIVE(handle,prefix)
+ *
+ * Example:
+ *
+ *      %YAML   1.1
+ *      %TAG    !   !foo
+ *      %TAG    !yaml!  tag:yaml.org,2002:
+ *      ---
+ *
+ * The corresponding sequence of tokens:
+ *
+ *      STREAM-START(utf-8)
+ *      VERSION-DIRECTIVE(1,1)
+ *      TAG-DIRECTIVE("!","!foo")
+ *      TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
+ *      DOCUMENT-START
+ *      STREAM-END
+ *
+ * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
+ * line.
+ *
+ * The document start and end indicators are represented by:
+ *
+ *      DOCUMENT-START
+ *      DOCUMENT-END
+ *
+ * Note that if a YAML stream contains an implicit document (without '---'
+ * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
+ * produced.
+ *
+ * In the following examples, we present whole documents together with the
+ * produced tokens.
+ *
+ *      1. An implicit document:
+ *
+ *          'a scalar'
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          SCALAR("a scalar",single-quoted)
+ *          STREAM-END
+ *
+ *      2. An explicit document:
+ *
+ *          ---
+ *          'a scalar'
+ *          ...
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          DOCUMENT-START
+ *          SCALAR("a scalar",single-quoted)
+ *          DOCUMENT-END
+ *          STREAM-END
+ *
+ *      3. Several documents in a stream:
+ *
+ *          'a scalar'
+ *          ---
+ *          'another scalar'
+ *          ---
+ *          'yet another scalar'
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          SCALAR("a scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("another scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("yet another scalar",single-quoted)
+ *          STREAM-END
+ *
+ * We have already introduced the SCALAR token above.  The following tokens are
+ * used to describe aliases, anchors, tag, and scalars:
+ *
+ *      ALIAS(anchor)
+ *      ANCHOR(anchor)
+ *      TAG(handle,suffix)
+ *      SCALAR(value,style)
+ *
+ * The following series of examples illustrate the usage of these tokens:
+ *
+ *      1. A recursive sequence:
+ *
+ *          &A [ *A ]
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          ANCHOR("A")
+ *          FLOW-SEQUENCE-START
+ *          ALIAS("A")
+ *          FLOW-SEQUENCE-END
+ *          STREAM-END
+ *
+ *      2. A tagged scalar:
+ *
+ *          !!float "3.14"  # A good approximation.
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          TAG("!!","float")
+ *          SCALAR("3.14",double-quoted)
+ *          STREAM-END
+ *
+ *      3. Various scalar styles:
+ *
+ *          --- # Implicit empty plain scalars do not produce tokens.
+ *          --- a plain scalar
+ *          --- 'a single-quoted scalar'
+ *          --- "a double-quoted scalar"
+ *          --- |-
+ *            a literal scalar
+ *          --- >-
+ *            a folded
+ *            scalar
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          DOCUMENT-START
+ *          DOCUMENT-START
+ *          SCALAR("a plain scalar",plain)
+ *          DOCUMENT-START
+ *          SCALAR("a single-quoted scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("a double-quoted scalar",double-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("a literal scalar",literal)
+ *          DOCUMENT-START
+ *          SCALAR("a folded scalar",folded)
+ *          STREAM-END
+ *
+ * Now it's time to review collection-related tokens. We will start with
+ * flow collections:
+ *
+ *      FLOW-SEQUENCE-START
+ *      FLOW-SEQUENCE-END
+ *      FLOW-MAPPING-START
+ *      FLOW-MAPPING-END
+ *      FLOW-ENTRY
+ *      KEY
+ *      VALUE
+ *
+ * The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
+ * FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
+ * correspondingly.  FLOW-ENTRY represent the ',' indicator.  Finally the
+ * indicators '?' and ':', which are used for denoting mapping keys and values,
+ * are represented by the KEY and VALUE tokens.
+ *
+ * The following examples show flow collections:
+ *
+ *      1. A flow sequence:
+ *
+ *          [item 1, item 2, item 3]
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          FLOW-SEQUENCE-START
+ *          SCALAR("item 1",plain)
+ *          FLOW-ENTRY
+ *          SCALAR("item 2",plain)
+ *          FLOW-ENTRY
+ *          SCALAR("item 3",plain)
+ *          FLOW-SEQUENCE-END
+ *          STREAM-END
+ *
+ *      2. A flow mapping:
+ *
+ *          {
+ *              a simple key: a value,  # Note that the KEY token is produced.
+ *              ? a complex key: another value,
+ *          }
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          FLOW-MAPPING-START
+ *          KEY
+ *          SCALAR("a simple key",plain)
+ *          VALUE
+ *          SCALAR("a value",plain)
+ *          FLOW-ENTRY
+ *          KEY
+ *          SCALAR("a complex key",plain)
+ *          VALUE
+ *          SCALAR("another value",plain)
+ *          FLOW-ENTRY
+ *          FLOW-MAPPING-END
+ *          STREAM-END
+ *
+ * A simple key is a key which is not denoted by the '?' indicator.  Note that
+ * the Scanner still produce the KEY token whenever it encounters a simple key.
+ *
+ * For scanning block collections, the following tokens are used (note that we
+ * repeat KEY and VALUE here):
+ *
+ *      BLOCK-SEQUENCE-START
+ *      BLOCK-MAPPING-START
+ *      BLOCK-END
+ *      BLOCK-ENTRY
+ *      KEY
+ *      VALUE
+ *
+ * The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
+ * increase that precedes a block collection (cf. the INDENT token in Python).
+ * The token BLOCK-END denote indentation decrease that ends a block collection
+ * (cf. the DEDENT token in Python).  However YAML has some syntax peculiarities
+ * that makes detections of these tokens more complex.
+ *
+ * The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
+ * '-', '?', and ':' correspondingly.
+ *
+ * The following examples show how the tokens BLOCK-SEQUENCE-START,
+ * BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
+ *
+ *      1. Block sequences:
+ *
+ *          - item 1
+ *          - item 2
+ *          -
+ *            - item 3.1
+ *            - item 3.2
+ *          -
+ *            key 1: value 1
+ *            key 2: value 2
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 2",plain)
+ *          BLOCK-ENTRY
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 3.1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 3.2",plain)
+ *          BLOCK-END
+ *          BLOCK-ENTRY
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("key 1",plain)
+ *          VALUE
+ *          SCALAR("value 1",plain)
+ *          KEY
+ *          SCALAR("key 2",plain)
+ *          VALUE
+ *          SCALAR("value 2",plain)
+ *          BLOCK-END
+ *          BLOCK-END
+ *          STREAM-END
+ *
+ *      2. Block mappings:
+ *
+ *          a simple key: a value   # The KEY token is produced here.
+ *          ? a complex key
+ *          : another value
+ *          a mapping:
+ *            key 1: value 1
+ *            key 2: value 2
+ *          a sequence:
+ *            - item 1
+ *            - item 2
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("a simple key",plain)
+ *          VALUE
+ *          SCALAR("a value",plain)
+ *          KEY
+ *          SCALAR("a complex key",plain)
+ *          VALUE
+ *          SCALAR("another value",plain)
+ *          KEY
+ *          SCALAR("a mapping",plain)
+ *          VALUE
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("key 1",plain)
+ *          VALUE
+ *          SCALAR("value 1",plain)
+ *          KEY
+ *          SCALAR("key 2",plain)
+ *          VALUE
+ *          SCALAR("value 2",plain)
+ *          BLOCK-END
+ *          KEY
+ *          SCALAR("a sequence",plain)
+ *          VALUE
+ *          BLOCK-SEQUENCE-START

+ *          SCALAR("item 2",plain)
+ *          BLOCK-END
+ *          BLOCK-END
+ *          STREAM-END
+ *
+ * YAML does not always require to start a new block collection from a new
+ * line.  If the current line contains only '-', '?', and ':' indicators, a new
+ * block collection may start at the current line.  The following examples
+ * illustrate this case:
+ *
+ *      1. Collections in a sequence:
+ *
+ *          - - item 1
+ *            - item 2
+ *          - key 1: value 1
+ *            key 2: value 2
+ *          - ? complex key
+ *            : complex value
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 1",plain)

+ *          BLOCK-END
+ *          STREAM-END
+ *

+ * This module defines a number of methods to facilitate completion
+ * and accesses input history from the Ruby interpreter.
+ * This module supported Edit Line(libedit) too.
+ * libedit is compatible with GNU Readline.
+ *
+ * GNU Readline:: http://www.gnu.org/directory/readline.html
+ * libedit::      http://www.thrysoee.dk/editline/
+ *
+ * Reads one inputted line with line edit by Readline.readline method.
+ * At this time, the facilitatation completion and the key
+ * bind like Emacs can be operated like GNU Readline.
+ *
+ *   require "readline"
+ *   while buf = Readline.readline("> ", true)
+ *     p buf
+ *   end
+ *
+ * The content that the user input can be recorded to the history.
+ * The history can be accessed by Readline::HISTORY constant.
+ *
+ *   require "readline"
+ *   while buf = Readline.readline("> ", true)
+ *     p Readline::HISTORY.to_a
+ *     print("-> ", buf, "\n")
+ *   end

+ *

+ *
+ * The String that is passed to the Proc depends on the

+ *
+ * == Completion for a Static List
+ *
+ *   require 'readline'
+ *
+ *   LIST = [
+ *     'search', 'download', 'open',
+ *     'help', 'history', 'quit',
+ *     'url', 'next', 'clear',

+ *
+ *   while line = Readline.readline('> ', true)

+ * completion.rb[https://git.ruby-lang.org/ruby.git/tree/lib/irb/completion.rb]
+ * file for irb.
+ *
+ * The common strategy is to take a list of possible completions and filter it
+ * down to those completions that start with the user input.  In the above
+ * examples Enumerator.grep is used.  The input is escaped to prevent Regexp
+ * special characters from interfering with the matching.

- *  A \File object is a representation of a file in the underlying platform.
- *
- *  \Class \File extends module FileTest, supporting such singleton methods
- *  as <tt>File.exist?</tt>.
- *
- *  == About the Examples
- *
- *  Many examples here use these variables:
- *
- *    :include: doc/examples/files.rdoc
- *
- *  == Access Modes
- *
- *  Methods File.new and File.open each create a \File object for a given file path.
- *
- *  === \String Access Modes
- *
- *  Methods File.new and File.open each may take string argument +mode+, which:
- *
- *  - Begins with a 1- or 2-character
- *    {read/write mode}[rdoc-ref:File@Read-2FWrite+Mode].
- *  - May also contain a 1-character {data mode}[rdoc-ref:File@Data+Mode].
- *  - May also contain a 1-character
- *    {file-create mode}[rdoc-ref:File@File-Create+Mode].
- *
- *  ==== Read/Write Mode
- *
- *  The read/write +mode+ determines:
- *
- *  - Whether the file is to be initially truncated.
- *
- *  - Whether reading is allowed, and if so:
- *
- *    - The initial read position in the file.
- *    - Where in the file reading can occur.
- *
- *  - Whether writing is allowed, and if so:
- *
- *    - The initial write position in the file.
- *    - Where in the file writing can occur.
- *
- *  These tables summarize:

- *  Note that modes <tt>'r'</tt> and <tt>'r+'</tt> are not allowed

- *
- *  In the tables:
- *
- *  - +Anywhere+ means that methods IO#rewind, IO#pos=, and IO#seek
- *    may be used to change the file's position,
- *    so that allowed reading or writing may occur anywhere in the file.
- *  - <tt>End only</tt> means that writing can occur only at end-of-file,
- *    and that methods IO#rewind, IO#pos=, and IO#seek do not affect writing.
- *  - +Error+ means that an exception is raised if disallowed reading or writing
- *    is attempted.
- *

- *  ==== \Data Mode
- *
- *  To specify whether data is to be treated as text or as binary data,
- *  either of the following may be suffixed to any of the string read/write modes
- *  above:
- *
- *  - <tt>'t'</tt>: Text data; sets the default external encoding
- *    to <tt>Encoding::UTF_8</tt>;
- *    on Windows, enables conversion between EOL and CRLF
- *    and enables interpreting <tt>0x1A</tt> as an end-of-file marker.
- *  - <tt>'b'</tt>: Binary data; sets the default external encoding
- *    to <tt>Encoding::ASCII_8BIT</tt>;
- *    on Windows, suppresses conversion between EOL and CRLF
- *    and disables interpreting <tt>0x1A</tt> as an end-of-file marker.
- *
- *  If neither is given, the stream defaults to text data.
- *
- *  Examples:
- *
- *    File.new('t.txt', 'rt')
- *    File.new('t.dat', 'rb')
- *
- *  When the data mode is specified, the read/write mode may not be omitted,
- *  and the data mode must precede the file-create mode, if given:
- *
- *    File.new('t.dat', 'b')   # Raises an exception.
- *    File.new('t.dat', 'rxb') # Raises an exception.
- *
- *  ==== \File-Create Mode
- *
- *  The following may be suffixed to any writable string mode above:
- *
- *  - <tt>'x'</tt>: Creates the file if it does not exist;
- *    raises an exception if the file exists.
- *
- *  Example:
- *
- *    File.new('t.tmp', 'wx')
- *
- *  When the file-create mode is specified, the read/write mode may not be omitted,
- *  and the file-create mode must follow the data mode:
- *
- *    File.new('t.dat', 'x')   # Raises an exception.
- *    File.new('t.dat', 'rxb') # Raises an exception.
- *
- *  === \Integer Access Modes
- *
- *  When mode is an integer it must be one or more of the following constants,
- *  which may be combined by the bitwise OR operator <tt>|</tt>:
- *
- *  - +File::RDONLY+: Open for reading only.
- *  - +File::WRONLY+: Open for writing only.
- *  - +File::RDWR+: Open for reading and writing.
- *  - +File::APPEND+: Open for appending only.
- *
- *  Examples:
- *
- *    File.new('t.txt', File::RDONLY)
- *    File.new('t.tmp', File::RDWR | File::CREAT | File::EXCL)
- *
- *  Note: Method IO#set_encoding does not allow the mode to be specified as an integer.
- *
- *  === File-Create Mode Specified as an \Integer
- *
- *  These constants may also be ORed into the integer mode:
- *
- *  - +File::CREAT+: Create file if it does not exist.
- *  - +File::EXCL+: Raise an exception if +File::CREAT+ is given and the file exists.
- *
- *  === \Data Mode Specified as an \Integer
- *
- *  \Data mode cannot be specified as an integer.
- *  When the stream access mode is given as an integer,
- *  the data mode is always text, never binary.
- *
- *  Note that although there is a constant +File::BINARY+,
- *  setting its value in an integer stream mode has no effect;
- *  this is because, as documented in File::Constants,
- *  the +File::BINARY+ value disables line code conversion,
- *  but does not change the external encoding.
- *
- *  === Encodings
- *
- *  Any of the string modes above may specify encodings -
- *  either external encoding only or both external and internal encodings -
- *  by appending one or both encoding names, separated by colons:
- *
- *    f = File.new('t.dat', 'rb')
- *    f.external_encoding # => #<Encoding:ASCII-8BIT>
- *    f.internal_encoding # => nil
- *    f = File.new('t.dat', 'rb:UTF-16')
- *    f.external_encoding # => #<Encoding:UTF-16 (dummy)>
- *    f.internal_encoding # => nil
- *    f = File.new('t.dat', 'rb:UTF-16:UTF-16')
- *    f.external_encoding # => #<Encoding:UTF-16 (dummy)>
- *    f.internal_encoding # => #<Encoding:UTF-16>
- *    f.close
- *
- *  The numerous encoding names are available in array Encoding.name_list:
- *
- *    Encoding.name_list.take(3) # => ["ASCII-8BIT", "UTF-8", "US-ASCII"]
- *
- *  When the external encoding is set, strings read are tagged by that encoding
- *  when reading, and strings written are converted to that encoding when
- *  writing.
- *
- *  When both external and internal encodings are set,
- *  strings read are converted from external to internal encoding,
- *  and strings written are converted from internal to external encoding.
- *  For further details about transcoding input and output,
- *  see {Encodings}[rdoc-ref:encodings.rdoc@Encodings].
- *
- *  If the external encoding is <tt>'BOM|UTF-8'</tt>, <tt>'BOM|UTF-16LE'</tt>
- *  or <tt>'BOM|UTF16-BE'</tt>,
- *  Ruby checks for a Unicode BOM in the input document
- *  to help determine the encoding.
- *  For UTF-16 encodings the file open mode must be binary.
- *  If the BOM is found,
- *  it is stripped and the external encoding from the BOM is used.
- *
- *  Note that the BOM-style encoding option is case insensitive,
- *  so <tt>'bom|utf-8'</tt> is also valid.
- *
- *  == \File Permissions
- *
- *  A \File object has _permissions_, an octal integer representing
- *  the permissions of an actual file in the underlying platform.
- *
- *  Note that file permissions are quite different from the _mode_
- *  of a file stream (\File object).
- *
- *  In a \File object, the permissions are available thus,
- *  where method +mode+, despite its name, returns permissions:
- *
- *    f = File.new('t.txt')
- *    f.lstat.mode.to_s(8) # => "100644"
- *
- *  On a Unix-based operating system,
- *  the three low-order octal digits represent the permissions
- *  for owner (6), group (4), and world (4).
- *  The triplet of bits in each octal digit represent, respectively,
- *  read, write, and execute permissions.
- *
- *  Permissions <tt>0644</tt> thus represent read-write access for owner
- *  and read-only access for group and world.
- *  See man pages {open(2)}[https://www.unix.com/man-page/bsd/2/open]
- *  and {chmod(2)}[https://www.unix.com/man-page/bsd/2/chmod].
- *
- *  For a directory, the meaning of the execute bit changes:
- *  when set, the directory can be searched.
- *
- *  Higher-order bits in permissions may indicate the type of file
- *  (plain, directory, pipe, socket, etc.) and various other special features.
- *
- *  On non-Posix operating systems, permissions may include only read-only or read-write,
- *  in which case, the remaining permission will resemble typical values.
- *  On Windows, for instance, the default permissions are <code>0644</code>;
- *  The only change that can be made is to make the file
+ *  A File is an abstraction of any file object accessible by the
+ *  program and is closely associated with class IO.  File includes
+ *  the methods of module FileTest as class methods, allowing you to
+ *  write (for example) <code>File.exist?("foo")</code>.
+ *
+ *  In the description of File methods,
+ *  <em>permission bits</em> are a platform-specific
+ *  set of bits that indicate permissions of a file. On Unix-based
+ *  systems, permissions are viewed as a set of three octets, for the
+ *  owner, the group, and the rest of the world. For each of these
+ *  entities, permissions may be set to read, write, or execute the
+ *  file:
+ *
+ *  The permission bits <code>0644</code> (in octal) would thus be
+ *  interpreted as read/write for owner, and read-only for group and
+ *  other. Higher-order bits may also be used to indicate the type of
+ *  file (plain, directory, pipe, socket, and so on) and various other
+ *  special features. If the permissions are for a directory, the
+ *  meaning of the execute bit changes; when set the directory can be
+ *  searched.
+ *
+ *  On non-Posix operating systems, there may be only the ability to
+ *  make a file read-only or read-write. In this case, the remaining
+ *  permission bits will be synthesized to resemble typical values. For
+ *  instance, on Windows NT the default permission bits are
+ *  <code>0644</code>, which means read/write for owner, read-only for
+ *  all others. The only change that can be made is to make the file
  *  read-only, which is reported as <code>0444</code>.
  *
- *  For a method that actually creates a file in the underlying platform
- *  (as opposed to merely creating a \File object),
- *  permissions may be specified:
- *
- *    File.new('t.tmp', File::CREAT, 0644)
- *    File.new('t.tmp', File::CREAT, 0444)
- *
- *  Permissions may also be changed:
- *
- *    f = File.new('t.tmp', File::CREAT, 0444)
- *    f.chmod(0644)
- *    f.chmod(0444)
- *
- *  == \File \Constants
- *
- *  Various constants for use in \File and IO methods
- *  may be found in module File::Constants;
- *  an array of their names is returned by <tt>File::Constants.constants</tt>.
+ *  Various constants for the methods in File can be found in File::Constants.
  *

  *  First, what's elsewhere. \Class \File:
  *
- *  - Inherits from {class IO}[rdoc-ref:IO@What-27s+Here],

  *    in particular, methods for creating, reading, and writing files
- *  - Includes module FileTest,
+ *  - Includes {module FileTest}[FileTest.html#module-FileTest-label-What-27s+Here].
  *    which provides dozens of additional methods.

-     * There are two families of constants here:
-     *
-     * - Those having to do with {file access}[rdoc-ref:File::Constants@File+Access].
-     * - Those having to do with {filename globbing}[rdoc-ref:File::Constants@Filename+Globbing+Constants+-28File-3A-3AFNM_-2A-29].
-     *
-     * \File constants defined for the local process may be retrieved
-     * with method File::Constants.constants:
-     *
-     *   File::Constants.constants.take(5)
-     *   # => [:RDONLY, :WRONLY, :RDWR, :APPEND, :CREAT]
-     *
-     * == \File Access
-     *
-     * \File-access constants may be used with optional argument +mode+ in calls
-     * to the following methods:
-     *
-     * - File.new.
-     * - File.open.
-     * - IO.for_fd.
-     * - IO.new.
-     * - IO.open.

-     * - IO.reopen.
-     * - IO.sysopen.
-     * - StringIO.new.
-     * - StringIO.open.
-     * - StringIO#reopen.
-     *
-     * === Read/Write Access
-     *
-     * Read-write access for a stream
-     * may be specified by a file-access constant.
-     *
-     * The constant may be specified as part of a bitwise OR of other such constants.
-     *
-     * Any combination of the constants in this section may be specified.
-     *
-     * ==== File::RDONLY
-     *
-     * Flag File::RDONLY specifies the the stream should be opened for reading only:
-     *
-     *   filepath = '/tmp/t.tmp'
-     *   f = File.new(filepath, File::RDONLY)
-     *   f.write('Foo') # Raises IOError (not opened for writing).
-     *
-     * ==== File::WRONLY
-     *
-     * Flag File::WRONLY specifies that the stream should be opened for writing only:
-     *
-     *   f = File.new(filepath, File::WRONLY)
-     *   f.read # Raises IOError (not opened for reading).
-     *
-     * ==== File::RDWR
-     *
-     * Flag File::RDWR specifies that the stream should be opened
-     * for both reading and writing:
-     *
-     *   f = File.new(filepath, File::RDWR)
-     *   f.write('Foo') # => 3
-     *   f.rewind       # => 0
-     *   f.read         # => "Foo"
-     *
-     * === \File Positioning
-     *
-     * ==== File::APPEND
-     *
-     * Flag File::APPEND specifies that the stream should be opened
-     * in append mode.
-     *
-     * Before each write operation, the position is set to end-of-stream.
-     * The modification of the position and the following write operation
-     * are performed as a single atomic step.
-     *
-     * ==== File::TRUNC
+     * File::Constants provides file-related constants.  All possible
+     * file constants are listed in the documentation but they may not all
+     * be present on your platform.
      *
-     * Flag File::TRUNC specifies that the stream should be truncated
-     * at its beginning.
-     * If the file exists and is successfully opened for writing,
-     * it is to be truncated to position zero;
-     * its ctime and mtime are updated.
-     *
-     * There is no effect on a FIFO special file or a terminal device.
-     * The effect on other file types is implementation-defined.
-     * The result of using File::TRUNC with File::RDONLY is undefined.
-     *
-     * === Creating and Preserving
-     *
-     * ==== File::CREAT
-     *
-     * Flag File::CREAT specifies that the stream should be created
-     * if it does not already exist.
-     *
-     * If the file exists:
-     *
-     *   - Raise an exception if File::EXCL is also specified.
-     *   - Otherwise, do nothing.
-     *
-     * If the file does not exist, then it is created.
-     * Upon successful completion, the atime, ctime, and mtime of the file are updated,
-     * and the ctime and mtime of the parent directory are updated.
-     *
-     * ==== File::EXCL
-     *
-     * Flag File::EXCL specifies that the stream should not already exist;
-     * If flags File::CREAT and File::EXCL are both specified
-     * and the stream already exists, an exception is raised.
-     *
-     * The check for the existence and creation of the file is performed as an
-     * atomic operation.
-     *
-     * If both File::EXCL and File::CREAT are specified and the path names a symbolic link,
-     * an exception is raised regardless of the contents of the symbolic link.
-     *
-     * If File::EXCL is specified and File::CREAT is not specified,
-     * the result is undefined.
-     *
-     * === POSIX \File \Constants
-     *
-     * Some file-access constants are defined only on POSIX-compliant systems;
-     * those are:
-     *
-     * - File::SYNC.
-     * - File::DSYNC.
-     * - File::RSYNC.
-     * - File::DIRECT.
-     * - File::NOATIME.
-     * - File::NOCTTY.
-     * - File::NOFOLLOW.
-     * - File::TMPFILE.
-     *
-     * ==== File::SYNC, File::RSYNC, and File::DSYNC
-     *
-     * Flag File::SYNC, File::RSYNC, or File::DSYNC
-     * specifies synchronization of I/O operations with the underlying file system.
-     *
-     * These flags are valid only for POSIX-compliant systems.
-     *
-     * - File::SYNC specifies that all write operations (both data and metadata)
-     *   are immediately to be flushed to the underlying storage device.
-     *   This means that the data is written to the storage device,
-     *   and the file's metadata (e.g., file size, timestamps, permissions)
-     *   are also synchronized.
-     *   This guarantees that data is safely stored on the storage medium
-     *   before returning control to the calling program.
-     *   This flag can have a significant impact on performance
-     *   since it requires synchronous writes, which can be slower
-     *   compared to asynchronous writes.
-     *
-     * - File::RSYNC specifies that any read operations on the file will not return
-     *   until all outstanding write operations
-     *   (those that have been issued but not completed) are also synchronized.
-     *   This is useful when you want to read the most up-to-date data,
-     *   which may still be in the process of being written.
-     *
-     * - File::DSYNC specifies that all _data_ write operations
-     *   are immediately to be flushed to the underlying storage device;
-     *   this differs from File::SYNC, which requires that _metadata_
-     *   also be synchronized.
-     *
-     * Note that the behavior of these flags may vary slightly
-     * depending on the operating system and filesystem being used.
-     * Additionally, using these flags can have an impact on performance
-     * due to the synchronous nature of the I/O operations,
-     * so they should be used judiciously,
-     * especially in performance-critical applications.
-     *
-     * ==== File::NOCTTY
-     *
-     * Flag File::NOCTTY specifies that if the stream is a terminal device,
-     * that device does not become the controlling terminal for the process.
-     *
-     * Defined only for POSIX-compliant systems.
-     *
-     * ==== File::DIRECT
-     *
-     * Flag File::DIRECT requests that cache effects of the I/O to and from the stream
-     * be minimized.
-     *
-     * Defined only for POSIX-compliant systems.
-     *
-     * ==== File::NOATIME
-     *
-     * Flag File::NOATIME specifies that act of opening the stream
-     * should not modify its access time (atime).
-     *
-     * Defined only for POSIX-compliant systems.
-     *
-     * ==== File::NOFOLLOW
-     *
-     * Flag File::NOFOLLOW specifies that if path is a symbolic link,
-     * it should not be followed.
-     *
-     * Defined only for POSIX-compliant systems.
-     *
-     * ==== File::TMPFILE
-     *
-     * Flag File::TMPFILE specifies that the opened stream
-     * should be a new temporary file.
-     *
-     * Defined only for POSIX-compliant systems.
-     *
-     * === Other File-Access \Constants
-     *
-     * ==== File::NONBLOCK
-     *
-     * When possible, the file is opened in nonblocking mode.
-     * Neither the open operation nor any subsequent I/O operations on
-     * the file will cause the calling process to wait.
-     *
-     * ==== File::BINARY
-     *
-     * Flag File::BINARY specifies that the stream is to be accessed in binary mode.
-     *
-     * ==== File::SHARE_DELETE (Windows Only)
-     *
-     * Flag File::SHARE_DELETE enables other processes to open the stream
-     * with delete access.
-     *
-     * If the stream is opened for (local) delete access without File::SHARE_DELETE,
-     * and another process attempts to open it with delete access,
-     * the attempt fails and the stream is not opened for that process.
-     *
-     * == Locking
-     *
-     * Four file constants relate to stream locking;
-     * see File#flock:
-     *
-     * ==== File::LOCK_EX
-     *
-     * Flag File::LOCK_EX specifies an exclusive lock;
-     * only one process a a time may lock the stream.
-     *
-     * ==== File::LOCK_NB
-     *
-     * Flag File::LOCK_NB specifies non-blocking locking for the stream;
-     * may be combined with File::LOCK_EX or File::LOCK_SH.
-     *
-     * ==== File::LOCK_SH
-     *
-     * Flag File::LOCK_SH specifies that multiple processes may lock
-     * the stream at the same time.
-     *
-     * ==== File::LOCK_UN
-     *
-     * Flag File::LOCK_UN specifies that the stream is not to be locked.
-     *
-     * == Filename Globbing \Constants (File::FNM_*)
-     *
-     * Filename-globbing constants may be used with optional argument +flags+
-     * in calls to the following methods:
-     *
-     * - Dir.glob.
-     * - File.fnmatch.
-     * - Pathname#fnmatch.
-     * - Pathname.glob.
-     * - Pathname#glob.
-     *
-     * The constants are:
-     *
-     * ==== File::FNM_CASEFOLD
-     *
-     * Flag File::FNM_CASEFOLD makes patterns case insensitive
-     * for File.fnmatch (but not Dir.glob).
-     *
-     * ==== File::FNM_DOTMATCH
-     *
-     * Flag File::FNM_DOTMATCH makes the <tt>'*'</tt> pattern
-     * match a filename starting with <tt>'.'</tt>.
-     *
-     * ==== File::FNM_EXTGLOB
-     *
-     * Flag File::FNM_EXTGLOB enables pattern <tt>'{_a_,_b_}'</tt>,
-     * which matches pattern '_a_' and pattern '_b_';
-     * behaves like
-     * a {regexp union}[rdoc-ref:Regexp.union]
-     * (e.g., <tt>'(?:_a_|_b_)'</tt>):
-     *
-     *   pattern = '{LEGAL,BSDL}'
-     *   Dir.glob(pattern)      # => ["LEGAL", "BSDL"]
-     *   Pathname.glob(pattern) # => [#<Pathname:LEGAL>, #<Pathname:BSDL>]
-     *   pathname.glob(pattern) # => [#<Pathname:LEGAL>, #<Pathname:BSDL>]
-     *
-     * ==== File::FNM_NOESCAPE
-     *
-     * Flag File::FNM_NOESCAPE disables <tt>'\'</tt> escaping.
-     *
-     * ==== File::FNM_PATHNAME
-     *
-     * Flag File::FNM_PATHNAME specifies that patterns <tt>'*'</tt> and <tt>'?'</tt>
-     * do not match the directory separator
-     * (the value of constant File::SEPARATOR).
-     *
-     * ==== File::FNM_SHORTNAME (Windows Only)
-     *
-     * Flag File::FNM_SHORTNAME Allows patterns to match short names if they exist.
-     *
-     * ==== File::FNM_SYSCASE
-     *
-     * Flag File::FNM_SYSCASE specifies that case sensitivity
-     * is the same as in the underlying operating system;
-     * effective for File.fnmatch, but not Dir.glob.
-     *
-     * == Other \Constants
-     *
-     * ==== File::NULL
-     *
-     * Flag File::NULL contains the string value of the null device:
-     *
-     * - On a Unix-like OS, <tt>'/dev/null'</tt>.
-     * - On Windows, <tt>'NUL'</tt>.
+     * If the underlying platform doesn't define a constant the corresponding
+     * Ruby constant is not defined.
      *
+     * Your platform documentations (e.g. man open(2)) may describe more
+     * detailed information.

  * Postponed Job API
- *
- * This API is designed to be called from contexts where it is not safe to run Ruby
- * code (e.g. because they do not hold the GVL or because GC is in progress), and
- * defer a callback to run in a context where it _is_ safe. The primary intended
- * users of this API is for sampling profilers like the "stackprof" gem; these work
- * by scheduling the periodic delivery of a SIGPROF signal, and inside the C-level
- * signal handler, deferring a job to collect a Ruby backtrace when it is next safe
- * to do so.
- *
- * Ruby maintains a small, fixed-size postponed job table. An extension using this
- * API should first call `rb_postponed_job_preregister` to register a callback
- * function in this table and obtain a handle of type `rb_postponed_job_handle_t`
- * to it. Subsequently, the callback can be triggered  by calling
- * `rb_postponed_job_trigger` with that handle, or the `data` associated with the
- * callback function can be changed by calling `rb_postponed_job_preregister` again.
- *
- * Because the postponed job table is quite small (it only has 32 entries on most
- * common systems), extensions should generally only preregister one or two `func`
- * values.
- *
- * Historically, this API provided two functions `rb_postponed_job_register` and
- * `rb_postponed_job_register_one`, which claimed to be fully async-signal-safe and
- * would call back the provided `func` and `data` at an appropriate time. However,
- * these functions were subject to race conditions which could cause crashes when
- * racing with Ruby's internal use of them. These two functions are still present,
- * but are marked as deprecated and have slightly changed semantics:
- *
- * * rb_postponed_job_register now works like rb_postponed_job_register_one i.e.
- *   `func` will only be executed at most one time each time Ruby checks for
- *   interrupts, no matter how many times it is registered
- * * They are also called with the last `data` to be registered, not the first
- *   (which is how rb_postponed_job_register_one previously worked)
+ * rb_postponed_job_register and rb_postponed_job_register_one are
+ * async-signal-safe and used via SIGPROF by the "stackprof" RubyGem

- * Schedules the given `func` to be called with `data` when Ruby next checks for
- * interrupts. If this function is called multiple times in between Ruby checking
- * for interrupts, then `func` will be called only once with the `data` value from
- * the first call to this function.
+ * There  are situations  when running  a ruby  program is  not possible.   For
+ * instance when  a program is in  a signal handler; for  another instance when
+ * the GC  is busy.   On such situations  however, there might  be needs  to do
+ * something.  We cannot but defer such operations until we are 100% sure it is
+ * safe  to execute  them.   This  mechanism is  called  postponed jobs.   This
+ * function  registers a  new one.   The registered  job would  eventually gets
+ * executed.
  *
- * Like `rb_postponed_job_trigger`, the context in which the job is called
- * holds the GVL and can allocate Ruby objects.
- *
- * This method essentially has the same semantics as:
- *
- * ```
- *   rb_postponed_job_trigger(rb_postponed_job_preregister(func, data));
- * ```
- *
- * @note    Previous versions of Ruby promised that the (`func`, `data`) pairs would
- *          be executed as many times as they were registered with this function; in
- *          reality this was always subject to race conditions and this function no
- *          longer provides this guarantee. Instead, multiple calls to this function
- *          can be coalesced into a single execution of the passed `func`, with the
- *          most recent `data` registered at that time passed in.
- *
- * @deprecated  This interface implies that arbitrarily many `func`'s can be enqueued
- *              over the lifetime of the program, whilst in reality the registration
- *              slots for postponed jobs are a finite resource. This is made clearer
- *              by the `rb_postponed_job_preregister` and `rb_postponed_job_trigger`
- *              functions, and a future version of Ruby might delete this function.

- * @shugo, author of  Apache httpd's mod_ruby module, requested  @matz for this
- * API.  He wanted a way so that mod_ruby can evaluate ruby scripts one by one,
- * separately, in each different contexts.  So  this function was made.  It was
- * designed to be a global interpreter entry point like ruby_run_node().
- *
- * The  way it  is implemented  however  allows extension  libraries (not  just
- * programs like  Apache httpd) to call  this function.  Because its  name says
- * nothing  about the  initial design,  people  started to  think of  it as  an
- * orthodox  way  to  call  ruby  level  `eval`  method  from  their  extension
- * libraries.  Even our `extension.rdoc` has had a description of this function
- * basically according to this understanding.
- *
- * The old  (mod_ruby like) usage still  works.  But over time,  usages of this
- * function from extension libraries got  popular, while mod_ruby faded out; is
- * no  longer maintained  now.  Devs  decided to  actively support  both.  This
- * function  now auto-detects  how  it is  called, and  switches  how it  works
- * depending on it.

- * functions.  In order to prevent  memory corruptions, objects observable from
- * C extensions are "pinned"; they stick to where they are born until they die,
- * just in  case any C  extensions touch their  raw pointers.  This  variant of
- * scheme  is   called  "Mostly-Copying"  garbage  collector.    Authors  of  C

+ * functions.  In order to prevent  memory corruptions, objects observable from
+ * C extensions are "pinned"; they stick to where they are born until they die,
+ * just in  case any C  extensions touch their  raw pointers.  This  variant of
+ * scheme  is   called  "Mostly-Copying"  garbage  collector.    Authors  of  C

-/**
- * @name  Errno handling routines for userland threads
- * @note  POSIX chapter 2 section 3 states  that for each thread  of a process,
- *        the  value of  `errno` shall  not be  affected by  function calls  or
- *        assignments to `errno` by other threads.
- *
- * Soooo this `#define  errno` below seems like a noob  mistake at first sight.
- * If you look at its actual  implementation, the functions are just adding one
- * level of indirection.  It doesn't make any sense sorry?  But yes!  @ko1 told
- * @shyouhei that this is inevitable.
- *
- * The  ultimate  reason is  because  Ruby  now  has N:M  threads  implemented.
- * Threads of that sort  change their context in user land.   A function can be
- * "transferred" between  threads in  middle of their  executions.  Let  us for
- * instance consider:
- *
- * ```cxx
- * void foo()
- * {
- *     auto i = errno;
- *     close(0);
- *     errno = i;
- * }
- * ```
- *
- * This function (if  ran under our Ractor) could change  its running thread at
- * the `close` function.  But the  two `errno` invocations are different!  Look
- * how the source code above is compiled by clang 17 with `-O3` flag @ Linux:
- *
- * ```
- * foo(int):                                # @foo(int)
- *         push    rbp
- *         push    r14
- *         push    rbx
- *         mov     ebx, edi
- *         call    __errno_location@PLT
- *         mov     r14, rax
- *         mov     ebp, dword ptr [rax]
- *         mov     edi, ebx
- *         call    close@PLT
- *         mov     dword ptr [r14], ebp
- *         pop     rbx
- *         pop     r14
- *         pop     rbp
- *         ret
- * ```
- *
- * Notice  how `__errno_location@PLT`  is  `call`-ed only  once.  The  compiler
- * assumes that the location of `errno` does not change during a function call.
- * Sadly this is  no longer true for us.  The  `close@PLT` now changes threads,
- * which should also change where `errno` is stored.
- *
- * With the `#define errno` below the compilation result changes to this:
- *
- * ```
- * foo(int):                                # @foo(int)
- *         push    rbp
- *         push    rbx
- *         push    rax
- *         mov     ebx, edi
- *         call    rb_errno_ptr()@PLT
- *         mov     ebp, dword ptr [rax]
- *         mov     edi, ebx
- *         call    close@PLT
- *         call    rb_errno_ptr()@PLT
- *         mov     dword ptr [rax], ebp
- *         add     rsp, 8
- *         pop     rbx
- *         pop     rbp
- *         ret
- * ```
- *
- * Which fixes the problem.

- *  (again, open for reading, writing, or both);
- *  when the block exits, the stream is closed,
- *  and the block's value is assigned to global variable <tt>$?</tt> and returned.
+ *  _cmd_ is a string or an array as follows.
  *
- *  Optional argument +mode+ may be any valid \IO mode.
- *  See {Access Modes}[rdoc-ref:File@Access+Modes].
+ *    cmd:
+ *      "-"                                      : fork
+ *      commandline                              : command line string which is passed to a shell
+ *      [env, cmdname, arg1, ..., opts]          : command name and zero or more arguments (no shell)
+ *      [env, [cmdname, argv0], arg1, ..., opts] : command name, argv[0] and zero or more arguments (no shell)
+ *    (env and opts are optional.)
  *
- *  Required argument +cmd+ determines which of the following occurs:
- *
- *  - The process forks.
- *  - A specified program runs in a shell.
- *  - A specified program runs with specified arguments.
- *  - A specified program runs with specified arguments and a specified +argv0+.
- *
- *  Each of these is detailed below.
- *
- *  The optional hash argument +env+ specifies name/value pairs that are to be added
- *  to the environment variables for the subprocess:
- *
- *    IO.popen({'FOO' => 'bar'}, 'ruby', 'r+') do |pipe|
- *      pipe.puts 'puts ENV["FOO"]'
- *      pipe.close_write
- *      pipe.gets
- *    end => "bar\n"
- *
- *  Optional keyword arguments +opts+ specify:
- *
- *  - {Open options}[rdoc-ref:IO@Open+Options].
- *  - {Encoding options}[rdoc-ref:encodings.rdoc@Encoding+Options].
- *  - Options for Kernel#spawn.
- *
- *  <b>Forked \Process</b>
- *
- *  When argument +cmd+ is the 1-character string <tt>'-'</tt>, causes the process to fork:
- *    IO.popen('-') do |pipe|
- *      if pipe
- *        $stderr.puts "In parent, child pid is #{pipe.pid}\n"
- *      else
- *        $stderr.puts "In child, pid is #{$$}\n"
- *      end
- *    end
- *
- *  Output:
+ *  If _cmd_ is a +String+ ``<code>-</code>'',
+ *  then a new instance of Ruby is started as the subprocess.
  *
- *    In parent, child pid is 26253
- *    In child, pid is 26253
+ *  If <i>cmd</i> is an +Array+ of +String+,
+ *  then it will be used as the subprocess's +argv+ bypassing a shell.
+ *  The array can contain a hash at first for environments and
+ *  a hash at last for options similar to #spawn.
  *
- *  Note that this is not supported on all platforms.
+ *  The default mode for the new file object is ``r'',
+ *  but <i>mode</i> may be set to any of the modes listed in the description for class IO.
+ *  The last argument <i>opt</i> qualifies <i>mode</i>.
  *
- *  <b>Shell Subprocess</b>
- *
- *  When argument +cmd+ is a single string (but not <tt>'-'</tt>),
- *  the program named +cmd+ is run as a shell command:
- *
- *    IO.popen('uname') do |pipe|
- *      pipe.readlines
- *    end
- *
- *  Output:
- *
- *    ["Linux\n"]
- *
- *  Another example:
- *
- *    IO.popen('/bin/sh', 'r+') do |pipe|
- *      pipe.puts('ls')
- *      pipe.close_write
- *      $stderr.puts pipe.readlines.size
- *    end
- *
- *  Output:
- *
- *    213
- *
- *  <b>Program Subprocess</b>
- *
- *  When argument +cmd+ is an array of strings,
- *  the program named <tt>cmd[0]</tt> is run with all elements of +cmd+ as its arguments:
- *
- *    IO.popen(['du', '..', '.']) do |pipe|
- *      $stderr.puts pipe.readlines.size
- *    end
- *
- *  Output:
- *
- *    1111
- *
- *  <b>Program Subprocess with <tt>argv0</tt></b>
- *
- *  When argument +cmd+ is an array whose first element is a 2-element string array
- *  and whose remaining elements (if any) are strings:
- *
- *  - <tt>cmd[0][0]</tt> (the first string in the nested array) is the name of a program that is run.
- *  - <tt>cmd[0][1]</tt> (the second string in the nested array) is set as the program's <tt>argv[0]</tt>.
- *  - <tt>cmd[1..-1]</tt> (the strings in the outer array) are the program's arguments.
- *
- *  Example (sets <tt>$0</tt> to 'foo'):
- *
- *    IO.popen([['/bin/sh', 'foo'], '-c', 'echo $0']).read # => "foo\n"
- *
- *  <b>Some Special Examples</b>
- *
- *    # Set IO encoding.
+ *    # set IO encoding
  *    IO.popen("nkf -e filename", :external_encoding=>"EUC-JP") {|nkf_io|
  *      euc_jp_string = nkf_io.read
  *    }
  *
- *    # Merge standard output and standard error using Kernel#spawn option. See Kernel#spawn.
- *    IO.popen(["ls", "/", :err=>[:child, :out]]) do |io|
- *      ls_result_with_error = io.read
- *    end
+ *    # merge standard output and standard error using
+ *    # spawn option.  See the document of Kernel.spawn.
+ *    IO.popen(["ls", "/", :err=>[:child, :out]]) {|ls_io|
+ *      ls_result_with_error = ls_io.read
+ *    }
  *
- *    # Use mixture of spawn options and IO options.
- *    IO.popen(["ls", "/"], :err=>[:child, :out]) do |io|
- *      ls_result_with_error = io.read
- *    end
+ *    # spawn options can be mixed with IO options
+ *    IO.popen(["ls", "/"], :err=>[:child, :out]) {|ls_io|
+ *      ls_result_with_error = ls_io.read
+ *    }
+ *
+ *  Raises exceptions which IO.pipe and Kernel.spawn raise.
+ *
+ *  If a block is given, Ruby will run the command as a child connected
+ *  to Ruby with a pipe. Ruby's end of the pipe will be passed as a
+ *  parameter to the block.
+ *  At the end of block, Ruby closes the pipe and sets <code>$?</code>.
+ *  In this case IO.popen returns the value of the block.
+ *
+ *  If a block is given with a _cmd_ of ``<code>-</code>'',
+ *  the block will be run in two separate processes: once in the parent,
+ *  and once in a child. The parent process will be passed the pipe

+ *  will be passed +nil+, and the child's standard in and

 /*
  *  call-seq:
- *    IO.new(fd, mode = 'r', **opts) -> io
+ *     IO.new(fd [, mode] [, opt])   -> io
  *
- *  Creates and returns a new \IO object (file stream) from a file descriptor.
+ *  Returns a new IO object (a stream) for the given integer file descriptor
+ *  +fd+ and +mode+ string.  +opt+ may be used to specify parts of +mode+ in a
+ *  more readable fashion.  See also IO.sysopen and IO.for_fd.
  *
- *  \IO.new may be useful for interaction with low-level libraries.
- *  For higher-level interactions, it may be simpler to create
- *  the file stream using File.open.
+ *  IO.new is called by various File and IO opening methods such as IO::open,
+ *  Kernel#open, and File::open.
  *
- *  Argument +fd+ must be a valid file descriptor (integer):
+ *  === Open Mode
  *
- *    path = 't.tmp'
- *    fd = IO.sysopen(path) # => 3
- *    IO.new(fd)            # => #<IO:fd 3>
+ *  When +mode+ is an integer it must be combination of the modes defined in
+ *  File::Constants (+File::RDONLY+, <code>File::WRONLY|File::CREAT</code>).
+ *  See the open(2) man page for more information.
  *
- *  The new \IO object does not inherit encoding
- *  (because the integer file descriptor does not have an encoding):
+ *  When +mode+ is a string it must be in one of the following forms:
  *
- *    fd = IO.sysopen('t.rus', 'rb')
- *    io = IO.new(fd)
- *    io.external_encoding # => #<Encoding:UTF-8> # Not ASCII-8BIT.
+ *    fmode
+ *    fmode ":" ext_enc
+ *    fmode ":" ext_enc ":" int_enc
+ *    fmode ":" "BOM|UTF-*"
  *
- *  Optional argument +mode+ (defaults to 'r') must specify a valid mode;
- *  see {Access Modes}[rdoc-ref:File@Access+Modes]:
+ *  +fmode+ is an IO open mode string, +ext_enc+ is the external encoding for
+ *  the IO and +int_enc+ is the internal encoding.
  *
- *    IO.new(fd, 'w')         # => #<IO:fd 3>
- *    IO.new(fd, File::WRONLY) # => #<IO:fd 3>
+ *  ==== IO Open Mode
  *
- *  Optional keyword arguments +opts+ specify:
+ *  Ruby allows the following open modes:
  *
- *  - {Open Options}[rdoc-ref:IO@Open+Options].
- *  - {Encoding options}[rdoc-ref:encodings.rdoc@Encoding+Options].
+ *  	"r"  Read-only, starts at beginning of file  (default mode).
  *
- *  Examples:
+ *  	"r+" Read-write, starts at beginning of file.
+ *
+ *  	"w"  Write-only, truncates existing file
+ *  	     to zero length or creates a new file for writing.
+ *
+ *  	"w+" Read-write, truncates existing file to zero length
+ *  	     or creates a new file for reading and writing.
+ *
+ *  	"a"  Write-only, each write call appends data at end of file.
+ *  	     Creates a new file for writing if file does not exist.
+ *
+ *  	"a+" Read-write, each write call appends data at end of file.
+ *	     Creates a new file for reading and writing if file does
+ *	     not exist.
+ *
+ *  The following modes must be used separately, and along with one or more of
+ *  the modes seen above.
+ *
+ *  	"b"  Binary file mode
+ *  	     Suppresses EOL <-> CRLF conversion on Windows. And
+ *  	     sets external encoding to ASCII-8BIT unless explicitly
+ *  	     specified.
+ *
+ *  	"t"  Text file mode
+ *
+ *  The exclusive access mode ("x") can be used together with "w" to ensure
+ *  the file is created. Errno::EEXIST is raised when it already exists.
+ *  It may not be supported with all kinds of streams (e.g. pipes).
+ *
+ *  When the open mode of original IO is read only, the mode cannot be
+ *  changed to be writable.  Similarly, the open mode cannot be changed from
+ *  write only to readable.
+ *
+ *  When such a change is attempted the error is raised in different locations
+ *  according to the platform.
  *
- *    IO.new(fd, internal_encoding: nil) # => #<IO:fd 3>
- *    IO.new(fd, autoclose: true)        # => #<IO:fd 3>
+ *  === IO Encoding
  *
+ *  When +ext_enc+ is specified, strings read will be tagged by the encoding
+ *  when reading, and strings output will be converted to the specified
+ *  encoding when writing.
+ *
+ *  When +ext_enc+ and +int_enc+ are specified read strings will be converted
+ *  from +ext_enc+ to +int_enc+ upon input, and written strings will be
+ *  converted from +int_enc+ to +ext_enc+ upon output.  See Encoding for
+ *  further details of transcoding on input and output.
+ *
+ *  If "BOM|UTF-8", "BOM|UTF-16LE" or "BOM|UTF16-BE" are used, Ruby checks for
+ *  a Unicode BOM in the input document to help determine the encoding.  For
+ *  UTF-16 encodings the file open mode must be binary.  When present, the BOM
+ *  is stripped and the external encoding from the BOM is used.  When the BOM
+ *  is missing the given Unicode encoding is used as +ext_enc+.  (The BOM-set
+ *  encoding option is case insensitive, so "bom|utf-8" is also valid.)
+ *
+ *  === Options
+ *
+ *  +opt+ can be used instead of +mode+ for improved readability.  The
+ *  following keys are supported:
+ *
+ *  :mode ::
+ *    Same as +mode+ parameter
+ *
+ *  :flags ::
+ *    Specifies file open flags as integer.
+ *    If +mode+ parameter is given, this parameter will be bitwise-ORed.
+ *
+ *  :\external_encoding ::
+ *    External encoding for the IO.
+ *
+ *  :\internal_encoding ::
+ *    Internal encoding for the IO.  "-" is a synonym for the default internal
+ *    encoding.
+ *
+ *    If the value is +nil+ no conversion occurs.
+ *
+ *  :encoding ::
+ *    Specifies external and internal encodings as "extern:intern".
+ *
+ *  :textmode ::
+ *    If the value is truth value, same as "t" in argument +mode+.
+ *
+ *  :binmode ::
+ *    If the value is truth value, same as "b" in argument +mode+.
+ *
+ *  :autoclose ::
+ *    If the value is +false+, the +fd+ will be kept open after this IO
+ *    instance gets finalized.
+ *
+ *  Also, +opt+ can have same keys in String#encode for controlling conversion
+ *  between the external encoding and the internal encoding.
+ *
+ *  === Example 1
+ *
+ *    fd = IO.sysopen("/dev/tty", "w")
+ *    a = IO.new(fd,"w")
+ *    $stderr.puts "Hello"
+ *    a.puts "World"
+ *
+ *  Produces:
+ *
+ *    Hello
+ *    World
+ *
+ *  === Example 2
+ *
+ *    require 'fcntl'
+ *
+ *    fd = STDERR.fcntl(Fcntl::F_DUPFD)
+ *    io = IO.new(fd, mode: 'w:UTF-16LE', cr_newline: true)
+ *    io.puts "Hello, World!"
+ *
+ *    fd = STDERR.fcntl(Fcntl::F_DUPFD)
+ *    io = IO.new(fd, mode: 'w', cr_newline: true,
+ *                external_encoding: Encoding::UTF_16LE)
+ *    io.puts "Hello, World!"
+ *
+ *  Both of above print "Hello, World!" in UTF-16LE to standard error output
+ *  with converting EOL generated by #puts to CR.

 /*
- *  An instance of class \IO (commonly called a _stream_)
- *  represents an input/output stream in the underlying operating system.
- *  \Class \IO is the basis for input and output in Ruby.
+ *  The IO class is the basis for all input and output in Ruby.
+ *  An I/O stream may be <em>duplexed</em> (that is, bidirectional), and
+ *  so may use more than one native operating system stream.
  *
- *  \Class File is the only class in the Ruby core that is a subclass of \IO.
- *  Some classes in the Ruby standard library are also subclasses of \IO;
- *  these include TCPSocket and UDPSocket.
+ *  Many of the examples in this section use the File class, the only standard
+ *  subclass of IO. The two classes are closely associated.  Like the File
+ *  class, the Socket library subclasses from IO (such as TCPSocket or
+ *  UDPSocket).
  *
- *  The global constant ARGF (also accessible as <tt>$<</tt>)
- *  provides an IO-like stream that allows access to all file paths
- *  found in ARGV (or found in STDIN if ARGV is empty).
- *  ARGF is not itself a subclass of \IO.
+ *  The Kernel#open method can create an IO (or File) object for these types
+ *  of arguments:
  *
- *  \Class StringIO provides an IO-like stream that handles a String.
- *  StringIO is not itself a subclass of \IO.
- *
- *  Important objects based on \IO include:
- *
- *  - $stdin.
- *  - $stdout.
- *  - $stderr.
- *  - Instances of class File.
- *
- *  An instance of \IO may be created using:
- *
- *  - IO.new: returns a new \IO object for the given integer file descriptor.
- *  - IO.open: passes a new \IO object to the given block.
- *  - IO.popen: returns a new \IO object that is connected to the $stdin and $stdout
- *    of a newly-launched subprocess.
- *  - Kernel#open: Returns a new \IO object connected to a given source:
- *    stream, file, or subprocess.
- *
- *  Like a File stream, an \IO stream has:
+ *  * A plain string represents a filename suitable for the underlying
+ *    operating system.
  *
- *  - A read/write mode, which may be read-only, write-only, or read/write;
- *    see {Read/Write Mode}[rdoc-ref:File@Read-2FWrite+Mode].
- *  - A data mode, which may be text-only or binary;
- *    see {Data Mode}[rdoc-ref:File@Data+Mode].
- *  - Internal and external encodings;
- *    see {Encodings}[rdoc-ref:File@Encodings].
+ *  * A string starting with <code>"|"</code> indicates a subprocess.
+ *    The remainder of the string following the <code>"|"</code> is
+ *    invoked as a process with appropriate input/output channels
+ *    connected to it.
+ *
+ *  * A string equal to <code>"|-"</code> will create another Ruby
+ *    instance as a subprocess.
+ *
+ *  The IO may be opened with different file modes (read-only, write-only) and
+ *  encodings for proper conversion.  See IO.new for these options.  See
+ *  Kernel#open for details of the various command formats described above.
+ *
+ *  IO.popen, the Open3 library, or  Process#spawn may also be used to
+ *  communicate with subprocesses through an IO.
+ *
+ *  Ruby will convert pathnames between different operating system
+ *  conventions if possible.  For instance, on a Windows system the
+ *  filename <code>"/gumby/ruby/test.rb"</code> will be opened as
+ *  <code>"\gumby\ruby\test.rb"</code>.  When specifying a Windows-style
+ *  filename in a Ruby string, remember to escape the backslashes:
+ *
+ *    "C:\\gumby\\ruby\\test.rb"
+ *
+ *  Our examples here will use the Unix-style forward slashes;
+ *  File::ALT_SEPARATOR can be used to get the platform-specific separator
+ *  character.
+ *
+ *  The global constant ARGF (also accessible as <code>$<</code>) provides an
+ *  IO-like stream which allows access to all files mentioned on the
+ *  command line (or STDIN if no files are mentioned). ARGF#path and its alias
+ *  ARGF#filename are provided to access the name of the file currently being
+ *  read.
+ *
+ *  == io/console
+ *
+ *  The io/console extension provides methods for interacting with the
+ *  console.  The console can be accessed from IO.console or the standard
+ *  input/output/error IO objects.
+ *
+ *  Requiring io/console adds the following methods:
+ *
+ *  * IO::console
+ *  * IO#raw
+ *  * IO#raw!
+ *  * IO#cooked
+ *  * IO#cooked!
+ *  * IO#getch

+ *  * IO#noecho
+ *  * IO#winsize
+ *  * IO#winsize=
+ *  * IO#iflush
+ *  * IO#ioflush
+ *  * IO#oflush
  *
- *  And like other \IO streams, it has:
+ *  Example:
  *
- *  - A position, which determines where in the stream the next
- *    read or write is to occur;
- *    see {Position}[rdoc-ref:IO@Position].
- *  - A line number, which is a special, line-oriented, "position"
- *    (different from the position mentioned above);
- *    see {Line Number}[rdoc-ref:IO@Line+Number].
+ *    require 'io/console'
+ *    rows, columns = $stdout.winsize
+ *    puts "Your screen is #{columns} wide and #{rows} tall"
  *
- *  == Extension <tt>io/console</tt>
+ *  == Example Files
  *
- *  Extension <tt>io/console</tt> provides numerous methods
- *  for interacting with the console;
- *  requiring it adds numerous methods to class \IO.
+ *  Many examples here use these filenames and their corresponding files:
  *
- *  == Example Files
+ *  - <tt>t.txt</tt>: A text-only file that is assumed to exist via:
  *
- *  Many examples here use these variables:
+ *      text = <<~EOT
+ *        This is line one.
+ *        This is the second line.
+ *        This is the third line.
+ *      EOT
+ *      File.write('t.txt', text)
  *
- *    :include: doc/examples/files.rdoc
+ *  - <tt>t.dat</tt>: A data file that is assumed to exist via:
  *
- *  == Open Options
+ *      data = "\u9990\u9991\u9992\u9993\u9994"
+ *      f = File.open('t.dat', 'wb:UTF-16')
+ *      f.write(data)
+ *      f.close
  *
- *  A number of \IO methods accept optional keyword arguments
- *  that determine how a new stream is to be opened:
+ *  - <tt>t.rus</tt>: A Russian-language text file that is assumed to exist via:
  *
- *  - +:mode+: Stream mode.
- *  - +:flags+: Integer file open flags;
- *    If +mode+ is also given, the two are bitwise-ORed.
- *  - +:external_encoding+: External encoding for the stream.
- *  - +:internal_encoding+: Internal encoding for the stream.
- *    <tt>'-'</tt> is a synonym for the default internal encoding.
- *    If the value is +nil+ no conversion occurs.
- *  - +:encoding+: Specifies external and internal encodings as <tt>'extern:intern'</tt>.
- *  - +:textmode+: If a truthy value, specifies the mode as text-only, binary otherwise.
- *  - +:binmode+: If a truthy value, specifies the mode as binary, text-only otherwise.
- *  - +:autoclose+: If a truthy value, specifies that the +fd+ will close
- *    when the stream closes; otherwise it remains open.
- *  - +:path:+ If a string value is provided, it is used in #inspect and is available as
- *    #path method.
+ *      File.write('t.rus', "\u{442 435 441 442}")
  *
- *  Also available are the options offered in String#encode,
- *  which may control conversion between external and internal encoding.
+ *  - <tt>t.tmp</tt>: A file that is assumed _not_ to exist.
  *
- *  == Basic \IO
+ *  == Modes
  *
- *  You can perform basic stream \IO with these methods,
- *  which typically operate on multi-byte strings:
+ *  A number of \IO method calls must or may specify a _mode_ for the stream;
+ *  the mode determines how stream is to be accessible, including:
  *
- *  - IO#read: Reads and returns some or all of the remaining bytes from the stream.
- *  - IO#write: Writes zero or more strings to the stream;
- *    each given object that is not already a string is converted via +to_s+.
+ *  - Whether the stream is to be read-only, write-only, or read-write.
+ *  - Whether the stream is positioned at its beginning or its end.
+ *  - Whether the stream treats data as text-only or binary.
+ *  - The external and internal encodings.
  *
- *  === Position
+ *  === Mode Specified as an \Integer
  *
- *  An \IO stream has a nonnegative integer _position_,
- *  which is the byte offset at which the next read or write is to occur.
- *  A new stream has position zero (and line number zero);
- *  method +rewind+ resets the position (and line number) to zero.
+ *  When +mode+ is an integer it must be one or more (combined by bitwise OR (<tt>|</tt>)
+ *  of the modes defined in File::Constants:
  *
- *  The relevant methods:
+ *  - +File::RDONLY+: Open for reading only.
+ *  - +File::WRONLY+: Open for writing only.
+ *  - +File::RDWR+: Open for reading and writing.
+ *  - +File::APPEND+: Open for appending only.
+ *  - +File::CREAT+: Create file if it does not exist.
+ *  - +File::EXCL+: Raise an exception if +File::CREAT+ is given and the file exists.
  *
- *  - IO#tell (aliased as +#pos+): Returns the current position (in bytes) in the stream.
- *  - IO#pos=: Sets the position of the stream to a given integer +new_position+ (in bytes).
- *  - IO#seek: Sets the position of the stream to a given integer +offset+ (in bytes),
- *    relative to a given position +whence+
- *    (indicating the beginning, end, or current position).
- *  - IO#rewind: Positions the stream at the beginning (also resetting the line number).
+ *  Examples:
  *
- *  === Open and Closed Streams
+ *    File.new('t.txt', File::RDONLY)
+ *    File.new('t.tmp', File::RDWR | File::CREAT | File::EXCL)
  *
- *  A new \IO stream may be open for reading, open for writing, or both.
+ *  Note: Method IO#set_encoding does not allow the mode to be specified as an integer.
  *
- *  A stream is automatically closed when claimed by the garbage collector.
+ *  === Mode Specified As a \String
  *
- *  Attempted reading or writing on a closed stream raises an exception.
+ *  When +mode+ is a string it must begin with one of the following:
  *
- *  The relevant methods:
+ *  - <tt>'r'</tt>: Read-only stream, positioned at the beginning;
+ *    the stream cannot be changed to writable.
+ *  - <tt>'w'</tt>: Write-only stream, positioned at the beginning;
+ *    the stream cannot be changed to readable.
+ *  - <tt>'a'</tt>: Write-only stream, positioned at the end;
+ *    every write appends to the end;
+ *    the stream cannot be changed to readable.
+ *  - <tt>'r+'</tt>: Read-write stream, positioned at the beginning.
+ *  - <tt>'w+'</tt>: Read-write stream, positioned at the end.
+ *  - <tt>'a+'</tt>: Read-write stream, positioned at the end.
  *
- *  - IO#close: Closes the stream for both reading and writing.
- *  - IO#close_read: Closes the stream for reading.
- *  - IO#close_write: Closes the stream for writing.
- *  - IO#closed?: Returns whether the stream is closed.
+ *  For a writable file stream (that is, any except read-only),
+ *  the file is truncated to zero if it exists,
+ *  and is created if it does not exist.
  *
- *  === End-of-Stream
+ *  Examples:
  *
- *  You can query whether a stream is positioned at its end:
+ *    File.open('t.txt', 'r')
+ *    File.open('t.tmp', 'w')
  *
- *  - IO#eof? (also aliased as +#eof+): Returns whether the stream is at end-of-stream.
+ *  Either of the following may be suffixed to any of the above:
  *
- *  You can reposition to end-of-stream by using method IO#seek:
+ *  - <tt>'t'</tt>: Text data; sets the default external encoding to +Encoding::UTF_8+;
+ *    on Windows, enables conversion between EOL and CRLF.
+ *  - <tt>'b'</tt>: Binary data; sets the default external encoding to +Encoding::ASCII_8BIT+;
+ *    on Windows, suppresses conversion between EOL and CRLF.
  *
- *    f = File.new('t.txt')
- *    f.eof? # => false
- *    f.seek(0, :END)
- *    f.eof? # => true
- *    f.close
+ *  If neither is given, the stream defaults to text data.
  *
- *  Or by reading all stream content (which is slower than using IO#seek):
+ *  Examples:
  *
- *    f.rewind
- *    f.eof? # => false
- *    f.read # => "First line\nSecond line\n\nFourth line\nFifth line\n"
- *    f.eof? # => true
+ *    File.open('t.txt', 'rt')
+ *    File.open('t.dat', 'rb')
  *
- *  == Line \IO
+ *  The following may be suffixed to any writable mode above:
  *
- *  You can read an \IO stream line-by-line using these methods:
+ *  - <tt>'x'</tt>: Creates the file if it does not exist;
+ *    raises an exception if the file exists.
  *
- *  - IO#each_line: Reads each remaining line, passing it to the given block.
- *  - IO#gets: Returns the next line.
- *  - IO#readline: Like #gets, but raises an exception at end-of-stream.
- *  - IO#readlines: Returns all remaining lines in an array.
+ *  Example:
  *
- *  Each of these reader methods accepts:
+ *    File.open('t.tmp', 'wx')
  *
- *  - An optional line separator, +sep+;
- *    see {Line Separator}[rdoc-ref:IO@Line+Separator].
- *  - An optional line-size limit, +limit+;
- *    see {Line Limit}[rdoc-ref:IO@Line+Limit].
+ *  Finally, the mode string may specify encodings --
+ *  either external encoding only or both external and internal encodings --
+ *  by appending one or both encoding names, separated by colons:
  *
- *  For each of these reader methods, reading may begin mid-line,
- *  depending on the stream's position;
- *  see {Position}[rdoc-ref:IO@Position]:
+ *    f = File.new('t.dat', 'rb')
+ *    f.external_encoding # => #<Encoding:ASCII-8BIT>
+ *    f.internal_encoding # => nil
+ *    f = File.new('t.dat', 'rb:UTF-16')
+ *    f.external_encoding # => #<Encoding:UTF-16 (dummy)>
+ *    f.internal_encoding # => nil
+ *    f = File.new('t.dat', 'rb:UTF-16:UTF-16')
+ *    f.external_encoding # => #<Encoding:UTF-16 (dummy)>
+ *    f.internal_encoding # => #<Encoding:UTF-16>
  *
- *    f = File.new('t.txt')
- *    f.pos = 27
- *    f.each_line {|line| p line }
- *    f.close
+ *  The numerous encoding names are available in array Encoding.name_list:
  *
- *  Output:
+ *    Encoding.name_list.size    # => 175
+ *    Encoding.name_list.take(3) # => ["ASCII-8BIT", "UTF-8", "US-ASCII"]
  *
- *    "rth line\n"
- *    "Fifth line\n"
+ *  == Encodings
  *
- *  You can write to an \IO stream line-by-line using this method:
+ *  When the external encoding is set,
+ *  strings read are tagged by that encoding
+ *  when reading, and strings written are converted to that
+ *  encoding when writing.
  *
- *  - IO#puts: Writes objects to the stream.
+ *  When both external and internal encodings are set,
+ *  strings read are converted from external to internal encoding,
+ *  and strings written are converted from internal to external encoding.
+ *  For further details about transcoding input and output, see Encoding.
  *
- *  === Line Separator
+ *  If the external encoding is <tt>'BOM|UTF-8'</tt>, <tt>'BOM|UTF-16LE'</tt>
+ *  or <tt>'BOM|UTF16-BE'</tt>, Ruby checks for
+ *  a Unicode BOM in the input document to help determine the encoding.  For
+ *  UTF-16 encodings the file open mode must be binary.
+ *  If the BOM is found, it is stripped and the external encoding from the BOM is used.
  *
- *  Each of these methods uses a <i>line separator</i>,
- *  which is the string that delimits lines:
+ *  Note that the BOM-style encoding option is case insensitive,
+ *  so 'bom|utf-8' is also valid.)
  *
- *  - IO.foreach.
- *  - IO.readlines.
- *  - IO#each_line.
- *  - IO#gets.
- *  - IO#readline.
- *  - IO#readlines.
+ *  == Open Options
  *
- *  The default line separator is the given by the global variable <tt>$/</tt>,
- *  whose value is by default <tt>"\n"</tt>.
- *  The line to be read next is all data from the current position
- *  to the next line separator:
+ *  A number of \IO methods accept an optional parameter +opts+,
+ *  which determines how a new stream is to be opened:

- *    f.gets        # => "e\n"
- *    f.close
+ *  == Getline Options
  *
- *  There are two special line separators:
+ *  A number of \IO methods accept optional keyword arguments
+ *  that determine how a stream is to be treated:
  *
- *  - +nil+: The entire stream is read into a single string:
+ *  - +:chomp+: If +true+, line separators are omitted; default is  +false+.
  *
- *      f = File.new('t.txt')
- *      f.gets(nil) # => "First line\nSecond line\n\nFourth line\nFifth line\n"
- *      f.close
+ *  == Position
  *
- *  - <tt>''</tt> (the empty string): The next "paragraph" is read
- *    (paragraphs being separated by two consecutive line separators):
+ *  An \IO stream has a _position_, which is the non-negative integer offset
+ *  (in bytes) in the stream where the next read or write will occur.
  *
- *      f = File.new('t.txt')
- *      f.gets('') # => "First line\nSecond line\n\n"
- *      f.gets('') # => "Fourth line\nFifth line\n"
- *      f.close
+ *  Note that a text stream may have multi-byte characters,
+ *  so a text stream whose position is +n+ (_bytes_) may not have +n+ _characters_
+ *  preceding the current position -- there may be fewer.
  *
- *  === Line Limit
+ *  A new stream is initially positioned:
  *
- *  Each of these methods uses a <i>line limit</i>,
- *  which specifies that the number of bytes returned may not be (much) longer
- *  than the given +limit+;
+ *  - At the beginning (position +0+)
+ *    if its mode is <tt>'r'</tt>, <tt>'w'</tt>, or <tt>'r+'</tt>.
+ *  - At the end (position <tt>self.size</tt>)
+ *    if its mode is <tt>'a'</tt>, <tt>'w+'</tt>, or <tt>'a+'</tt>.
  *
- *  - IO.foreach.
- *  - IO.readlines.
- *  - IO#each_line.
- *  - IO#gets.
- *  - IO#readline.
- *  - IO#readlines.
+ *  Methods to query the position:
  *
- *  A multi-byte character will not be split, and so a line may be slightly longer
- *  than the given limit.
+ *  - IO#tell and its alias IO#pos return the position for an open stream.
+ *  - IO#eof? and its alias IO#eof return whether the position is at the end
+ *    of a readable stream.
  *
- *  If +limit+ is not given, the line is determined only by +sep+.
+ *  Reading from a stream usually changes its position:
  *
- *    # Text with 1-byte characters.
- *    File.open('t.txt') {|f| f.gets(1) }  # => "F"
- *    File.open('t.txt') {|f| f.gets(2) }  # => "Fi"
- *    File.open('t.txt') {|f| f.gets(3) }  # => "Fir"
- *    File.open('t.txt') {|f| f.gets(4) }  # => "Firs"
- *    # No more than one line.
- *    File.open('t.txt') {|f| f.gets(10) } # => "First line"
- *    File.open('t.txt') {|f| f.gets(11) } # => "First line\n"
- *    File.open('t.txt') {|f| f.gets(12) } # => "First line\n"
+ *    f = File.open('t.txt')
+ *    f.tell     # => 0
+ *    f.readline # => "This is line one.\n"
+ *    f.tell     # => 19
+ *    f.readline # => "This is the second line.\n"
+ *    f.tell     # => 45
+ *    f.eof?     # => false
+ *    f.readline # => "Here's the third line.\n"
+ *    f.eof?     # => true
  *
- *    # Text with 2-byte characters, which will not be split.
- *    File.open('t.rus') {|f| f.gets(1).size } # => 1
- *    File.open('t.rus') {|f| f.gets(2).size } # => 1
- *    File.open('t.rus') {|f| f.gets(3).size } # => 2
- *    File.open('t.rus') {|f| f.gets(4).size } # => 2
  *
- *  === Line Separator and Line Limit
+ *  Writing to a stream usually changes its position:
  *
- *  With arguments +sep+ and +limit+ given,
- *  combines the two behaviors:
+ *    f = File.open('t.tmp', 'w')
+ *    f.tell         # => 0
+ *    f.write('foo') # => 3
+ *    f.tell         # => 3
+ *    f.write('bar') # => 3
+ *    f.tell         # => 6
  *
- *  - Returns the next line as determined by line separator +sep+.
- *  - But returns no more bytes than are allowed by the limit.
  *
- *  Example:
+ *  Iterating over a stream usually changes its position:
  *
- *    File.open('t.txt') {|f| f.gets('li', 20) } # => "First li"
- *    File.open('t.txt') {|f| f.gets('li', 2) }  # => "Fi"
+ *    f = File.open('t.txt')
+ *    f.each do |line|
+ *      p "position=#{f.pos} eof?=#{f.eof?} line=#{line}"
+ *    end
  *
- *  === Line Number
+ *  Output:
  *
- *  A readable \IO stream has a non-negative integer <i>line number</i>.
+ *    "position=19 eof?=false line=This is line one.\n"
+ *    "position=45 eof?=false line=This is the second line.\n"
+ *    "position=70 eof?=true line=This is the third line.\n"
  *
- *  The relevant methods:
+ *  The position may also be changed by certain other methods:
  *
- *  - IO#lineno: Returns the line number.
- *  - IO#lineno=: Resets and returns the line number.
+ *  - IO#pos= and IO#seek change the position to a specified offset.
+ *  - IO#rewind changes the position to the beginning.
  *
- *  Unless modified by a call to method IO#lineno=,
- *  the line number is the number of lines read
- *  by certain line-oriented methods,
- *  according to the given line separator +sep+:
+ *  == Line Number
  *
- *  - IO.foreach: Increments the line number on each call to the block.
- *  - IO#each_line: Increments the line number on each call to the block.
- *  - IO#gets: Increments the line number.
- *  - IO#readline: Increments the line number.
- *  - IO#readlines: Increments the line number for each line read.
+ *  A readable \IO stream has a _line_ _number_,
+ *  which is the non-negative integer line number
+ *  in the stream where the next read will occur.
  *
- *  A new stream is initially has line number zero (and position zero);
- *  method +rewind+ resets the line number (and position) to zero:
+ *  A new stream is initially has line number +0+.

- *    f.close
+ *  \Method IO#lineno returns the line number.

+ *    f = File.open('t.txt', 'r')
  *    f.lineno   # => 0

- *  the line number does not affect where the next read or write will occur:
- *

- *    f.lineno = 1000
- *    f.lineno # => 1000

- *    f.close
- *

- *
- *  - When a stream is opened, <tt>$.</tt> is not set;
- *    its value is left over from previous activity in the process:

- *      $. = 41
- *      f = File.new('t.txt')
- *      $. = 41
- *      # => 41
- *      f.close
- *
- *  - When a stream is read, <tt>$.</tt> is set to the line number for that stream:

- *      f0 = File.new('t.txt')
- *      f1 = File.new('t.dat')
- *      f0.readlines # => ["First line\n", "Second line\n", "\n", "Fourth line\n", "Fifth line\n"]

  *  Document-class: IO::Buffer
  *
- *  IO::Buffer is a efficient zero-copy buffer for input/output. There are
- *  typical use cases:
+ *  IO::Buffer is a low-level efficient buffer for input/output. There are three
+ *  ways of using buffer:
  *
- *  * Create an empty buffer with ::new, fill it with buffer using #copy or
- *    #set_value, #set_string, get buffer with #get_string or write it directly
- *    to some file with #write.
+ *  * Create an empty buffer with ::new, fill it with data using #copy or
+ *    #set_value, #set_string, get data with #get_string;
  *  * Create a buffer mapped to some string with ::for, then it could be used
  *    both for reading with #get_string or #get_value, and writing (writing will
- *    change the source string, too).
+ *    change the source string, too);
  *  * Create a buffer mapped to some file with ::map, then it could be used for
  *    reading and writing the underlying file.
- *  * Create a string of a fixed size with ::string, then #read into it, or
- *    modify it using #set_value.
  *
  *  Interaction with string and file memory is performed by efficient low-level
  *  C mechanisms like `memcpy`.
  *
  *  The class is meant to be an utility for implementing more high-level mechanisms
- *  like Fiber::Scheduler#io_read and Fiber::Scheduler#io_write and parsing binary
- *  protocols.
+ *  like Fiber::SchedulerInterface#io_read and Fiber::SchedulerInterface#io_write.

 # frozen_string_literal: true
 #
-# \Module \Base64 provides methods for:
+# = base64.rb: methods for base64-encoding and -decoding strings
 #
-# - Encoding a binary string (containing non-ASCII characters)
-#   as a string of printable ASCII characters.
-# - Decoding such an encoded string.
-#
-# \Base64 is commonly used in contexts where binary data
-# is not allowed or supported:
-#
-# - Images in HTML or CSS files, or in URLs.
-# - Email attachments.
-#
-# A \Base64-encoded string is about one-third larger that its source.
-# See the {Wikipedia article}[https://en.wikipedia.org/wiki/Base64]
-# for more information.
-#
-# This module provides three pairs of encode/decode methods.
-# Your choices among these methods should depend on:
-#
-# - Which character set is to be used for encoding and decoding.
-# - Whether "padding" is to be used.
-# - Whether encoded strings are to contain newlines.
-#
-# Note: Examples on this page assume that the including program has executed:
-#
-#   require 'base64'
-#
-# == Encoding Character Sets
-#
-# A \Base64-encoded string consists only of characters from a 64-character set:
-#
-# - <tt>('A'..'Z')</tt>.
-# - <tt>('a'..'z')</tt>.
-# - <tt>('0'..'9')</tt>.
-# - <tt>=</tt>, the 'padding' character.
-# - Either:
-#   - <tt>%w[+ /]</tt>:
-#     {RFC-2045-compliant}[https://datatracker.ietf.org/doc/html/rfc2045];
-#     _not_ safe for URLs.
-#   - <tt>%w[- _]</tt>:
-#     {RFC-4648-compliant}[https://datatracker.ietf.org/doc/html/rfc4648];
-#     safe for URLs.
-#
-# If you are working with \Base64-encoded strings that will come from
-# or be put into URLs, you should choose this encoder-decoder pair
-# of RFC-4648-compliant methods:
-#
-# - Base64.urlsafe_encode64 and Base64.urlsafe_decode64.
-#
-# Otherwise, you may choose any of the pairs in this module,
-# including the pair above, or the RFC-2045-compliant pairs:
-#
-# - Base64.encode64 and Base64.decode64.
-# - Base64.strict_encode64 and Base64.strict_decode64.
-#
-# == Padding
-#
-# \Base64-encoding changes a triplet of input bytes
-# into a quartet of output characters.
-#
-# <b>Padding in Encode Methods</b>
-#
-# Padding -- extending an encoded string with zero, one, or two trailing
-# <tt>=</tt> characters -- is performed by methods Base64.encode64,
-# Base64.strict_encode64, and, by default, Base64.urlsafe_encode64:
-#
-#   Base64.encode64('s')                         # => "cw==\n"
-#   Base64.strict_encode64('s')                  # => "cw=="
-#   Base64.urlsafe_encode64('s')                 # => "cw=="
-#   Base64.urlsafe_encode64('s', padding: false) # => "cw"
-#
-# When padding is performed, the encoded string is always of length <em>4n</em>,
-# where +n+ is a non-negative integer:
-#
-# - Input bytes of length <em>3n</em> generate unpadded output characters
-#   of length <em>4n</em>:
-#
-#     # n = 1:  3 bytes => 4 characters.
-#     Base64.strict_encode64('123')      # => "MDEy"
-#     # n = 2:  6 bytes => 8 characters.
-#     Base64.strict_encode64('123456')   # => "MDEyMzQ1"
-#
-# - Input bytes of length <em>3n+1</em> generate padded output characters
-#   of length <em>4(n+1)</em>, with two padding characters at the end:
-#
-#     # n = 1:  4 bytes => 8 characters.
-#     Base64.strict_encode64('1234')     # => "MDEyMw=="
-#     # n = 2:  7 bytes => 12 characters.
-#     Base64.strict_encode64('1234567')  # => "MDEyMzQ1Ng=="
-#
-# - Input bytes of length <em>3n+2</em> generate padded output characters
-#   of length <em>4(n+1)</em>, with one padding character at the end:
-#
-#     # n = 1:  5 bytes => 8 characters.
-#     Base64.strict_encode64('12345')    # => "MDEyMzQ="
-#     # n = 2:  8 bytes => 12 characters.
-#     Base64.strict_encode64('12345678') # => "MDEyMzQ1Njc="
-#
-# When padding is suppressed, for a positive integer <em>n</em>:
-#
-# - Input bytes of length <em>3n</em> generate unpadded output characters
-#   of length <em>4n</em>:
-#
-#     # n = 1:  3 bytes => 4 characters.
-#     Base64.urlsafe_encode64('123', padding: false)      # => "MDEy"
-#     # n = 2:  6 bytes => 8 characters.
-#     Base64.urlsafe_encode64('123456', padding: false)   # => "MDEyMzQ1"
-#
-# - Input bytes of length <em>3n+1</em> generate unpadded output characters
-#   of length <em>4n+2</em>, with two padding characters at the end:
-#
-#     # n = 1:  4 bytes => 6 characters.
-#     Base64.urlsafe_encode64('1234', padding: false)     # => "MDEyMw"
-#     # n = 2:  7 bytes => 10 characters.
-#     Base64.urlsafe_encode64('1234567', padding: false)  # => "MDEyMzQ1Ng"
-#
-# - Input bytes of length <em>3n+2</em> generate unpadded output characters
-#   of length <em>4n+3</em>, with one padding character at the end:
-#
-#     # n = 1:  5 bytes => 7 characters.
-#     Base64.urlsafe_encode64('12345', padding: false)    # => "MDEyMzQ"
-#     # m = 2:  8 bytes => 11 characters.
-#     Base64.urlsafe_encode64('12345678', padding: false) # => "MDEyMzQ1Njc"
-#
-# <b>Padding in Decode Methods</b>
-#
-# All of the \Base64 decode methods support (but do not require) padding.
-#
-# \Method Base64.decode64 does not check the size of the padding:
-#
-#   Base64.decode64("MDEyMzQ1Njc") # => "01234567"
-#   Base64.decode64("MDEyMzQ1Njc=") # => "01234567"
-#   Base64.decode64("MDEyMzQ1Njc==") # => "01234567"
-#
-# \Method Base64.strict_decode64 strictly enforces padding size:
-#
-#   Base64.strict_decode64("MDEyMzQ1Njc")   # Raises ArgumentError
-#   Base64.strict_decode64("MDEyMzQ1Njc=")  # => "01234567"
-#   Base64.strict_decode64("MDEyMzQ1Njc==") # Raises ArgumentError
-#
-# \Method Base64.urlsafe_decode64 allows padding in +str+,
-# which if present, must be correct:
-# see {Padding}[Base64.html#module-Base64-label-Padding], above:
-#
-#   Base64.urlsafe_decode64("MDEyMzQ1Njc") # => "01234567"
-#   Base64.urlsafe_decode64("MDEyMzQ1Njc=") # => "01234567"
-#   Base64.urlsafe_decode64("MDEyMzQ1Njc==") # Raises ArgumentError.
-#
-# == Newlines
-#
-# An encoded string returned by Base64.encode64 or Base64.urlsafe_encode64
-# has an embedded newline character
-# after each 60-character sequence, and, if non-empty, at the end:
-#
-#   # No newline if empty.
-#   encoded = Base64.encode64("\x00" *  0)
-#   encoded.index("\n") # => nil
-#
-#   # Newline at end of short output.
-#   encoded = Base64.encode64("\x00" *  1)
-#   encoded.size        # => 4
-#   encoded.index("\n") # => 4
+
+# The Base64 module provides for the encoding (#encode64, #strict_encode64,
+# #urlsafe_encode64) and decoding (#decode64, #strict_decode64,
+# #urlsafe_decode64) of binary data using a Base64 representation.
 #
-#   # Newline at end of longer output.
-#   encoded = Base64.encode64("\x00" * 45)
-#   encoded.size        # => 60
-#   encoded.index("\n") # => 60

 \fBbundle binstubs\fR \fIGEM_NAME\fR [\-\-force] [\-\-path PATH] [\-\-standalone]

 .SH "DESCRIPTION"
 Binstubs are scripts that wrap around executables\. Bundler creates a small Ruby file (a binstub) that loads Bundler, runs the command, and puts it into \fBbin/\fR\. Binstubs are a shortcut\-or alternative\- to always using \fBbundle exec\fR\. This gives you a file that can be run directly, and one that will always run the correct gem version used by the application\.
+.
 .P
 For example, if you run \fBbundle binstubs rspec\-core\fR, Bundler will create the file \fBbin/rspec\fR\. That file will contain enough code to load Bundler, tell it to load the bundled gems, and then run rspec\.
+.
 .P
 This command generates binstubs for executables in \fBGEM_NAME\fR\. Binstubs are put into \fBbin\fR, or the \fB\-\-path\fR directory if one has been set\. Calling binstubs with [GEM [GEM]] will create binstubs for all given gems\.

This needs to be enabled via the \fB\-\-all\-platforms\fR option\. This setting will be remembered in your local bundler configuration\.
+.
 .SH "REMOTE FETCHING"
-By default, if you run \fBbundle install(1)\fR \fIbundle\-install\.1\.html\fR after running bundle cache(1) \fIbundle\-cache\.1\.html\fR, bundler will still connect to \fBrubygems\.org\fR to check whether a platform\-specific gem exists for any of the gems in \fBvendor/cache\fR\.

+.
 .P
 For instance, consider this Gemfile(5):
+.
 .IP "" 4
+.
 .nf
+
 source "https://rubygems\.org"
 
 gem "nokogiri"
+.
 .fi
+.
 .IP "" 0
+.
 .P
 If you run \fBbundle cache\fR under C Ruby, bundler will retrieve the version of \fBnokogiri\fR for the \fB"ruby"\fR platform\. If you deploy to JRuby and run \fBbundle install\fR, bundler is forced to check to see whether a \fB"java"\fR platformed \fBnokogiri\fR exists\.
+.
 .P
 Even though the \fBnokogiri\fR gem for the Ruby platform is \fItechnically\fR acceptable on JRuby, it has a C extension that does not run on JRuby\. As a result, bundler will, by default, still connect to \fBrubygems\.org\fR to check whether it has a version of one of your gems more specific to your platform\.
+.
 .P
 This problem is also not limited to the \fB"java"\fR platform\. A similar (common) problem can happen when developing on Windows and deploying to Linux, or even when developing on OSX and deploying to Linux\.
+.
 .P
 If you know for sure that the gems packaged in \fBvendor/cache\fR are appropriate for the platform you are on, you can run \fBbundle install \-\-local\fR to skip checking for more appropriate gems, and use the ones in \fBvendor/cache\fR\.
+.
 .P
 One way to be sure that you have the right platformed versions of all your gems is to run \fBbundle cache\fR on an identical machine and check in the gems\. For instance, you can run \fBbundle cache\fR on an identical staging box during your staging process, and check in the \fBvendor/cache\fR before deploying to production\.
+.
 .P
 By default, bundle cache(1) \fIbundle\-cache\.1\.html\fR fetches and also installs the gems to the default location\. To package the dependencies to \fBvendor/cache\fR without installing them to the local install location, you can run \fBbundle cache \-\-no\-install\fR\.
+.
 .SH "HISTORY"
 In Bundler 2\.1, \fBcache\fR took in the functionalities of \fBpackage\fR and now \fBpackage\fR and \fBpack\fR are aliases of \fBcache\fR\.

-Now instead of checking out the remote git repository, the local override will be used\.

 Install the gems specified in your Gemfile(5)\. If this is the first time you run bundle install (and a \fBGemfile\.lock\fR does not exist), Bundler will fetch all remote sources, resolve dependencies and install all needed gems\.

+.
+.P
+As a result, you should run \fBbundle install\fR as the current user, and Bundler will ask for your password if it is needed to put the gems into their final location\.
+.
 .SH "INSTALLING GROUPS"
 By default, \fBbundle install\fR will install all gems in all groups in your Gemfile(5), except those declared for a different platform\.
+.
 .P
 However, you can explicitly tell Bundler to skip installing certain groups with the \fB\-\-without\fR option\. This option takes a space\-separated list of groups\.
+.
 .P
 While the \fB\-\-without\fR option will skip \fIinstalling\fR the gems in the specified groups, it will still \fIdownload\fR those gems and use them to resolve the dependencies of every gem in your Gemfile(5)\.
+.
 .P
 This is so that installing a different set of groups on another machine (such as a production server) will not change the gems and versions that you have already developed and tested against\.
+.
 .P
 \fBBundler offers a rock\-solid guarantee that the third\-party code you are running in development and testing is also the third\-party code you are running in production\. You can choose to exclude some of that code in different environments, but you will never be caught flat\-footed by different versions of third\-party code being used in different environments\.\fR
+.
 .P
 For a simple illustration, consider the following Gemfile(5):
+.
 .IP "" 4
+.
 .nf
-source 'https://rubygems\.org'
 
-gem 'sinatra'
+source \'https://rubygems\.org\'
+
+gem \'sinatra\'
 
 group :production do
-  gem 'rack\-perftools\-profiler'
+  gem \'rack\-perftools\-profiler\'
 end
+.
 .fi
+.
 .IP "" 0
+.
 .P
 In this case, \fBsinatra\fR depends on any version of Rack (\fB>= 1\.0\fR), while \fBrack\-perftools\-profiler\fR depends on 1\.x (\fB~> 1\.0\fR)\.
+.
 .P
 When you run \fBbundle install \-\-without production\fR in development, we look at the dependencies of \fBrack\-perftools\-profiler\fR as well\. That way, you do not spend all your time developing against Rack 2\.0, using new APIs unavailable in Rack 1\.x, only to have Bundler switch to Rack 1\.2 when the \fBproduction\fR group \fIis\fR used\.
+.
 .P
 This should not cause any problems in practice, because we do not attempt to \fBinstall\fR the gems in the excluded groups, and only evaluate as part of the dependency resolution process\.
+.
 .P
 This also means that you cannot include different versions of the same gem in different groups, because doing so would result in different sets of dependencies used in development and production\. Because of the vagaries of the dependency resolution process, this usually affects more than the gems you list in your Gemfile(5), and can (surprisingly) radically change the gems you are using\.
+.
 .SH "THE GEMFILE\.LOCK"
 When you run \fBbundle install\fR, Bundler will persist the full names and versions of all gems that you used (including dependencies of the gems specified in the Gemfile(5)) into a file called \fBGemfile\.lock\fR\.
+.
 .P
 Bundler uses this file in all subsequent calls to \fBbundle install\fR, which guarantees that you always use the same exact code, even as your application moves across machines\.
+.
 .P
 Because of the way dependency resolution works, even a seemingly small change (for instance, an update to a point\-release of a dependency of a gem in your Gemfile(5)) can result in radically different gems being needed to satisfy all dependencies\.
+.
 .P
 As a result, you \fBSHOULD\fR check your \fBGemfile\.lock\fR into version control, in both applications and gems\. If you do not, every machine that checks out your repository (including your production server) will resolve all dependencies again, which will result in different versions of third\-party code being used if \fBany\fR of the gems in the Gemfile(5) or any of their dependencies have been updated\.
+.
 .P
 When Bundler first shipped, the \fBGemfile\.lock\fR was included in the \fB\.gitignore\fR file included with generated gems\. Over time, however, it became clear that this practice forces the pain of broken dependencies onto new contributors, while leaving existing contributors potentially unaware of the problem\. Since \fBbundle install\fR is usually the first step towards a contribution, the pain of broken dependencies would discourage new contributors from contributing\. As a result, we have revised our guidance for gem authors to now recommend checking in the lock for gems\.
+.
 .SH "CONSERVATIVE UPDATING"
 When you make a change to the Gemfile(5) and then run \fBbundle install\fR, Bundler will update only the gems that you modified\.
+.
 .P
 In other words, if a gem that you \fBdid not modify\fR worked before you called \fBbundle install\fR, it will continue to use the exact same versions of all dependencies as it used before the update\.
+.
 .P
-Let's take a look at an example\. Here's your original Gemfile(5):
+Let\'s take a look at an example\. Here\'s your original Gemfile(5):

+gem \'activemerchant\'
+.
 .fi
+.
 .IP "" 0
+.
 .P
 In this case, both \fBactionpack\fR and \fBactivemerchant\fR depend on \fBactivesupport\fR\. The \fBactionpack\fR gem depends on \fBactivesupport 2\.3\.8\fR and \fBrack ~> 1\.1\.0\fR, while the \fBactivemerchant\fR gem depends on \fBactivesupport >= 2\.3\.2\fR, \fBbraintree >= 2\.0\.0\fR, and \fBbuilder >= 2\.0\.0\fR\.
+.
 .P
 When the dependencies are first resolved, Bundler will select \fBactivesupport 2\.3\.8\fR, which satisfies the requirements of both gems in your Gemfile(5)\.
+.
 .P
 Next, you modify your Gemfile(5) to:
+.
 .IP "" 4
+.
 .nf
-source 'https://rubygems\.org'
 
-gem 'actionpack', '3\.0\.0\.rc'
-gem 'activemerchant'
+source \'https://rubygems\.org\'
+
+gem \'actionpack\', \'3\.0\.0\.rc\'
+gem \'activemerchant\'
+.
 .fi
+.
 .IP "" 0
+.
 .P
 The \fBactionpack 3\.0\.0\.rc\fR gem has a number of new dependencies, and updates the \fBactivesupport\fR dependency to \fB= 3\.0\.0\.rc\fR and the \fBrack\fR dependency to \fB~> 1\.2\.1\fR\.
+.
 .P
 When you run \fBbundle install\fR, Bundler notices that you changed the \fBactionpack\fR gem, but not the \fBactivemerchant\fR gem\. It evaluates the gems currently being used to satisfy its requirements:
+.
 .TP
 \fBactivesupport 2\.3\.8\fR
 also used to satisfy a dependency in \fBactivemerchant\fR, which is not being updated
+.
 .TP
 \fBrack ~> 1\.1\.0\fR
 not currently being used to satisfy another dependency
+.
 .P
 Because you did not explicitly ask to update \fBactivemerchant\fR, you would not expect it to suddenly stop working after updating \fBactionpack\fR\. However, satisfying the new \fBactivesupport 3\.0\.0\.rc\fR dependency of actionpack requires updating one of its dependencies\.
+.
 .P
 Even though \fBactivemerchant\fR declares a very loose dependency that theoretically matches \fBactivesupport 3\.0\.0\.rc\fR, Bundler treats gems in your Gemfile(5) that have not changed as an atomic unit together with their dependencies\. In this case, the \fBactivemerchant\fR dependency is treated as \fBactivemerchant 1\.7\.1 + activesupport 2\.3\.8\fR, so \fBbundle install\fR will report that it cannot update \fBactionpack\fR\.
+.
 .P
 To explicitly update \fBactionpack\fR, including its dependencies which other gems in the Gemfile(5) still depend on, run \fBbundle update actionpack\fR (see \fBbundle update(1)\fR)\.
+.
 .P
 \fBSummary\fR: In general, after making a change to the Gemfile(5) , you should first try to run \fBbundle install\fR, which will guarantee that no other gem in the Gemfile(5) is impacted by the change\. If that does not work, run bundle update(1) \fIbundle\-update\.1\.html\fR\.

 .P
 When is it practical to use \fBbundle pristine\fR?
+.
 .P
 It comes in handy when a developer is debugging a gem\. \fBbundle pristine\fR is a great way to get rid of experimental changes to a gem that one may not want\.
+.
 .P
 Why use \fBbundle pristine\fR over \fBgem pristine \-\-all\fR?
+.
 .P
 Both commands are very similar\. For context: \fBbundle pristine\fR, without arguments, cleans all gems from the lockfile\. Meanwhile, \fBgem pristine \-\-all\fR cleans all installed gems for that Ruby version\.
+.
 .P
 If a developer forgets which gems in their project they might have been debugging, the Rubygems \fBgem pristine [GEMNAME]\fR command may be inconvenient\. One can avoid waiting for \fBgem pristine \-\-all\fR, and instead run \fBbundle pristine\fR\.

 As you can see, even though you have two gems in the Gemfile(5), your application needs 26 different gems in order to run\. Bundler remembers the exact versions it installed in \fBGemfile\.lock\fR\.

 .P
 However, from time to time, you might want to update the gems you are using to the newest versions that still match the gems in your Gemfile(5)\.
+.
 .P
 To do this, run \fBbundle update \-\-all\fR, which will ignore the \fBGemfile\.lock\fR, and resolve all the dependencies again\. Keep in mind that this process can result in a significantly different set of the 25 gems, based on the requirements of new gems that the gem authors released since the last time you ran \fBbundle update \-\-all\fR\.
+.
 .SH "UPDATING A LIST OF GEMS"
 Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\.
+.
 .P
 For instance, in the scenario above, imagine that \fBnokogiri\fR releases version \fB1\.4\.4\fR, and you want to update it \fIwithout\fR updating Rails and all of its dependencies\. To do this, run \fBbundle update nokogiri\fR\.
+.
 .P
 Bundler will update \fBnokogiri\fR and any of its dependencies, but leave alone Rails and its dependencies\.
+.
 .SH "OVERLAPPING DEPENDENCIES"
 Sometimes, multiple gems declared in your Gemfile(5) are satisfied by the same second\-level dependency\. For instance, consider the case of \fBthin\fR and \fBrack\-perftools\-profiler\fR\.

 .P
 In short, by default, when you update a gem using \fBbundle update\fR, bundler will update all dependencies of that gem, including those that are also dependencies of another gem\.
+.
 .P
 To prevent updating indirect dependencies, prior to version 1\.14 the only option was the \fBCONSERVATIVE UPDATING\fR behavior in bundle install(1) \fIbundle\-install\.1\.html\fR:
+.
 .P
 In this scenario, updating the \fBthin\fR version manually in the Gemfile(5), and then running bundle install(1) \fIbundle\-install\.1\.html\fR will only update \fBdaemons\fR and \fBeventmachine\fR, but not \fBrack\fR\. For more information, see the \fBCONSERVATIVE UPDATING\fR section of bundle install(1) \fIbundle\-install\.1\.html\fR\.
+.
 .P
 Starting with 1\.14, specifying the \fB\-\-conservative\fR option will also prevent indirect dependencies from being updated\.
+.
 .SH "PATCH LEVEL OPTIONS"
 Version 1\.14 introduced 4 patch\-level options that will influence how gem versions are resolved\. One of the following options can be used: \fB\-\-patch\fR, \fB\-\-minor\fR or \fB\-\-major\fR\. \fB\-\-strict\fR can be added to further influence resolution\.
+.
 .TP

+.

 Providing one of the patch level options (e\.g\. \fB\-\-patch\fR) changes the sort order of the satisfying versions, causing Bundler to consider the latest \fB\-\-patch\fR or \fB\-\-minor\fR version available before other versions\. Note that versions outside the stated patch level could still be resolved to if necessary to find a suitable dependency graph\.

-For example, if gem 'foo' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
+For example, if gem \'foo\' is locked at 1\.0\.2, with no gem requirement defined in the Gemfile, and versions 1\.0\.3, 1\.0\.4, 1\.1\.0, 1\.1\.1, 2\.0\.0 all exist, the default order of preference by default (\fB\-\-major\fR) will be "2\.0\.0, 1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
+.
 .P
 If the \fB\-\-patch\fR option is used, the order of preference will change to "1\.0\.4, 1\.0\.3, 1\.0\.2, 1\.1\.1, 1\.1\.0, 2\.0\.0"\.
+.
 .P
 If the \fB\-\-minor\fR option is used, the order of preference will change to "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2, 2\.0\.0"\.
+.
 .P
 Combining the \fB\-\-strict\fR option with any of the patch level options will remove any versions beyond the scope of the patch level option, to ensure that no gem is updated that far\.
+.
 .P
 To continue the previous example, if both \fB\-\-patch\fR and \fB\-\-strict\fR options are used, the available versions for resolution would be "1\.0\.4, 1\.0\.3, 1\.0\.2"\. If \fB\-\-minor\fR and \fB\-\-strict\fR are used, it would be "1\.1\.1, 1\.1\.0, 1\.0\.4, 1\.0\.3, 1\.0\.2"\.
+.
 .P
-Gem requirements as defined in the Gemfile will still be the first determining factor for what versions are available\. If the gem requirement for \fBfoo\fR in the Gemfile is '~> 1\.0', that will accomplish the same thing as providing the \fB\-\-minor\fR and \fB\-\-strict\fR options\.

 .SH "NAME"
 \fBGemfile\fR \- A format for describing gem dependencies for Ruby programs
+.
 .SH "SYNOPSIS"
 A \fBGemfile\fR describes the gem dependencies required to execute associated Ruby code\.
+.
 .P
 Place the \fBGemfile\fR in the root of the directory containing the associated code\. For instance, in a Rails application, place the \fBGemfile\fR in the same directory as the \fBRakefile\fR\.
+.
 .SH "SYNTAX"
 A \fBGemfile\fR is evaluated as Ruby code, in a context which makes available a number of methods used to describe the gem requirements\.
+.
 .SH "GLOBAL SOURCE"
 At the top of the \fBGemfile\fR, add a single line for the \fBRubyGems\fR source that contains the gems listed in the \fBGemfile\fR\.
+.
 .IP "" 4
+.
 .nf
+
 source "https://rubygems\.org"

 .IP "" 0
+.
 .P
 You can add only one global source\. In Bundler 1\.13, adding multiple global sources was deprecated\. The \fBsource\fR \fBMUST\fR be a valid RubyGems repository\.
+.
 .P
 To use more than one source of RubyGems, you should use \fI\fBsource\fR block\fR\.
+.
 .P
 A source is checked for gems following the heuristics described in \fISOURCE PRIORITY\fR\.
+.
 .P
 \fBNote about a behavior of the feature deprecated in Bundler 1\.13\fR: If a gem is found in more than one global source, Bundler will print a warning after installing the gem indicating which source was used, and listing the other sources where the gem is available\. A specific source can be selected for gems that need to use a non\-standard repository, suppressing this warning, by using the \fI\fB:source\fR option\fR or \fBsource\fR block\.
+.
 .SS "CREDENTIALS"
 Some gem sources require a username and password\. Use bundle config(1) \fIbundle\-config\.1\.html\fR to set the username and password for any of the sources that need it\. The command must be run once on each computer that will install the Gemfile, but this keeps the credentials from being stored in plain text in version control\.

 Also, calling \fBBundler\.setup\fR with no parameters, or calling \fBrequire "bundler/setup"\fR will setup all groups except for the ones you excluded via \fB\-\-without\fR (since they are not available)\.
+.
 .P
 Note that on \fBbundle install\fR, bundler downloads and evaluates all gems, in order to create a single canonical list of all of the required gems and their dependencies\. This means that you cannot list different versions of the same gems in different groups\. For more details, see Understanding Bundler \fIhttps://bundler\.io/rationale\.html\fR\.
+.
 .SS "PLATFORMS"
 If a gem should only be used in a particular platform or set of platforms, you can specify them\. Platforms are essentially identical to groups, except that you do not need to use the \fB\-\-without\fR install\-time flag to exclude groups of gems for other platforms\.
+.
 .P
 There are a number of \fBGemfile\fR platforms:
+.
 .TP
 \fBruby\fR
 C Ruby (MRI), Rubinius, or TruffleRuby, but not Windows
+.
 .TP
 \fBmri\fR
 C Ruby (MRI) only, but not Windows

 .P
 On platforms \fBruby\fR, \fBmri\fR, \fBmswin\fR, \fBmswin64\fR, and \fBwindows\fR, you may additionally specify a version by appending the major and minor version numbers without a delimiter\. For example, to specify that a gem should only be used on platform \fBruby\fR version 3\.1, use:
+.
 .IP "" 4

 .P
 This forces the gem to be loaded from this source and ignores the global source declared at the top level of the file\. If the gem does not exist in this source, it will not be installed\.
+.
 .P
 Bundler will search for child dependencies of this gem by first looking in the source selected for the parent, but if they are not found there, it will fall back on the global source\.
+.
 .P
 \fBNote about a behavior of the feature deprecated in Bundler 1\.13\fR: Selecting a specific source repository this way also suppresses the ambiguous gem warning described above in \fIGLOBAL SOURCE\fR\.
+.
 .P
 Using the \fB:source\fR option for an individual gem will also make that source available as a possible global source for any other gems which do not specify explicit sources\. Thus, when adding gems with explicit sources, it is recommended that you also ensure all other gems in the Gemfile are using explicit sources\.
+.
 .SS "GIT"
 If necessary, you can specify that a gem is located at a particular git repository using the \fB:git\fR parameter\. The repository can be accessed via several protocols:
+.
 .TP
 \fBHTTP(S)\fR
 gem "rails", git: "https://github\.com/rails/rails\.git"

+.
 .P
 \fBNOTE\fR: \fBhttp://\fR and \fBgit://\fR URLs should be avoided if at all possible\. These protocols are unauthenticated, so a man\-in\-the\-middle attacker can deliver malicious code and compromise your system\. HTTPS and SSH are strongly preferred\.
+.

 The \fBgroup\fR, \fBplatforms\fR, and \fBrequire\fR options are available and behave exactly the same as they would for a normal gem\.

 .P
 A git repository \fBSHOULD\fR have at least one file, at the root of the directory containing the gem, with the extension \fB\.gemspec\fR\. This file \fBMUST\fR contain a valid gem specification, as expected by the \fBgem build\fR command\.
+.
 .P
 If a git repository does not have a \fB\.gemspec\fR, bundler will attempt to create one, but it will not contain any dependencies, executables, or C extension compilation instructions\. As a result, it may fail to properly integrate into your application\.
+.
 .P
 If a git repository does have a \fB\.gemspec\fR for the gem you attached it to, a version specifier, if provided, means that the git repository is only valid if the \fB\.gemspec\fR specifies a version matching the version specifier\. If not, bundler will print a warning\.

 \fBsubmodules\fR
 For reference, a git submodule \fIhttps://git\-scm\.com/book/en/v2/Git\-Tools\-Submodules\fR lets you have another git repository within a subfolder of your repository\. Specify \fBsubmodules: true\fR to cause bundler to expand any submodules included in the git repository
+.
 .P

 When attempting to locate a gem to satisfy a gem requirement, bundler uses the following priority order:

+.
 .IP "2." 4
 For implicit gems (dependencies of explicit gems), any source, git, or path repository declared on the parent\. This results in bundler prioritizing the ActiveSupport gem from the Rails git repository over ones from \fBrubygems\.org\fR
+.
 .IP "3." 4
 If neither of the above conditions are met, the global source will be used\. If multiple global sources are specified, they will be prioritized from last to first, but this is deprecated since Bundler 1\.13, so Bundler prints a warning and will abort with an error in the future\.

 # <%= config[:constant_name] %>
 
-TODO: Delete this and the text below, and describe your gem
-
 Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/<%= config[:namespaced_path] %>`. To experiment with that code, run `bin/console` for an interactive prompt.
 
-## Installation
+TODO: Delete this and the text above, and describe your gem
 
-TODO: Replace `UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG` with your gem name right after releasing it to RubyGems.org. Please do not do it earlier due to security reasons. Alternatively, replace this section with instructions to install your gem from git if you don't plan to release to RubyGems.org.
+## Installation
 
 Install the gem and add to the application's Gemfile by executing:
 
-    $ bundle add UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+    $ bundle add <%= config[:name] %>
 
 If bundler is not being used to manage dependencies, install the gem by executing:
 
-    $ gem install UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+    $ gem install <%= config[:name] %>

 #
-# === Copying
+# This module has all methods of Bundler::FileUtils module, but it outputs messages
+# before acting.  This equates to passing the <tt>:verbose</tt> flag to methods
+# in Bundler::FileUtils.
 #
-# - ::copy_entry: Recursively copies an entry.
-# - ::copy_file: Copies an entry.
-# - ::copy_stream: Copies a stream.
-# - ::cp, ::copy: Copies files.
-# - ::cp_lr: Recursively creates hard links.
-# - ::cp_r: Recursively copies files, retaining mode, owner, and group.
-# - ::install: Recursively copies files, optionally setting mode,
-#   owner, and group.
+# == module Bundler::FileUtils::NoWrite
 #
-# === Moving
+# This module has all methods of Bundler::FileUtils module, but never changes
+# files/directories.  This equates to passing the <tt>:noop</tt> flag to methods
+# in Bundler::FileUtils.
 #
-# - ::mv, ::move: Moves entries.
+# == module Bundler::FileUtils::DryRun
 #
-# === Options
-#
-# - ::collect_method: Returns the names of methods that accept a given option.
-# - ::commands: Returns the names of methods that accept options.
-# - ::have_option?: Returns whether a given method accepts a given option.
-# - ::options: Returns all option names.
-# - ::options_of: Returns the names of the options for a given method.
-#
-# == Path Arguments
-#
-# Some methods in \Bundler::FileUtils accept _path_ arguments,
-# which are interpreted as paths to filesystem entries:
-#
-# - If the argument is a string, that value is the path.
-# - If the argument has method +:to_path+, it is converted via that method.
-# - If the argument has method +:to_str+, it is converted via that method.
-#
-# == About the Examples
-#
-# Some examples here involve trees of file entries.
-# For these, we sometimes display trees using the
-# {tree command-line utility}[https://en.wikipedia.org/wiki/Tree_(command)],
-# which is a recursive directory-listing utility that produces
-# a depth-indented listing of files and directories.
-#
-# We use a helper method to launch the command and control the format:
-#
-#   def tree(dirpath = '.')
-#     command = "tree --noreport --charset=ascii #{dirpath}"
-#     system(command)
-#   end
-#
-# To illustrate:
-#
-#   tree('src0')
-#   # => src0
-#   #    |-- sub0
-#   #    |   |-- src0.txt
-#   #    |   `-- src1.txt
-#   #    `-- sub1
-#   #        |-- src2.txt
-#   #        `-- src3.txt
-#
-# == Avoiding the TOCTTOU Vulnerability
-#
-# For certain methods that recursively remove entries,
-# there is a potential vulnerability called the
-# {Time-of-check to time-of-use}[https://en.wikipedia.org/wiki/Time-of-check_to_time-of-use],
-# or TOCTTOU, vulnerability that can exist when:
-#
-# - An ancestor directory of the entry at the target path is world writable;
-#   such directories include <tt>/tmp</tt>.
-# - The directory tree at the target path includes:
-#
-#   - A world-writable descendant directory.
-#   - A symbolic link.
-#
-# To avoid that vulnerability, you can use this method to remove entries:
-#
-# - Bundler::FileUtils.remove_entry_secure: removes recursively
-#   if the target path points to a directory.
-#
-# Also available are these methods,
-# each of which calls \Bundler::FileUtils.remove_entry_secure:
-#
-# - Bundler::FileUtils.rm_r with keyword argument <tt>secure: true</tt>.
-# - Bundler::FileUtils.rm_rf with keyword argument <tt>secure: true</tt>.
-#
-# Finally, this method for moving entries calls \Bundler::FileUtils.remove_entry_secure
-# if the source and destination are on different file systems
-# (which means that the "move" is really a copy and remove):
-#
-# - Bundler::FileUtils.mv with keyword argument <tt>secure: true</tt>.
-#
-# \Method \Bundler::FileUtils.remove_entry_secure removes securely
-# by applying a special pre-process:
-#
-# - If the target path points to a directory, this method uses methods
-#   {File#chown}[rdoc-ref:File#chown]
-#   and {File#chmod}[rdoc-ref:File#chmod]
-#   in removing directories.
-# - The owner of the target directory should be either the current process
-#   or the super user (root).
-#
-# WARNING: You must ensure that *ALL* parent directories cannot be
-# moved by other untrusted users.  For example, parent directories
-# should not be owned by untrusted users, and should not be world
-# writable except when the sticky bit is set.
-#
-# For details of this security vulnerability, see Perl cases:
-#
-# - {CVE-2005-0448}[https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0448].
-# - {CVE-2004-0452}[https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0452].
+# This module has all methods of Bundler::FileUtils module, but never changes
+# files/directories.  This equates to passing the <tt>:noop</tt> and
+# <tt>:verbose</tt> flags to methods in Bundler::FileUtils.

-  #
-  # Where possible, Bundler::PubGrub will accept user-defined types, so long as they quack.
-  #
-  # ## "Package":
-  #
-  # This class will be used to represent the various packages being solved for.
-  # .to_s will be called when displaying errors and debugging info, it should
-  # probably return the package's name.
-  # It must also have a reasonable definition of #== and #hash
-  #
-  # Example classes: String ("rails")

-  # ## "Version":
-  #
-  # This class will be used to represent a single version number.
-  #
-  # Versions don't need to store their associated package, however they will
-  # only be compared against other versions of the same package.

-  # It must be Comparible (and implement <=> reasonably)

-  # parse_dependency to convert it to a format Bundler::PubGrub understands.

-  #
-  # The returned string consists of the elements of +enum+,

-  #
-  # Simple examples:
-  #
-  #   Bundler::URI.encode_www_form([['foo', 0], ['bar', 1], ['baz', 2]])
-  #   # => "foo=0&bar=1&baz=2"

-  #   # => "f%23o=%2F&b-r=%24&b+z=%40"

   #
-  # When +enum+ is Array-like, each element +ele+ is converted to a field:
+  # This decodes + to SP.
   #
-  # - If +ele+ is an array of two or more elements,
-  #   the field is formed from its first two elements

-  #   Example:
-  #
-  #     Bundler::URI.encode_www_form([['foo'], [:bar], [0]])
-  #     # => "foo&bar&0"

+# ERB::Compiler
+class ERB
+  # = ERB::Compiler
+  #
+  # Compiles ERB templates into Ruby code; the compiled code produces the
+  # template result when evaluated. ERB::Compiler provides hooks to define how
+  # generated output is handled.
+  #
+  # Internally ERB does something like this to generate the code returned by
+  # ERB#src:
+  #
+  #   compiler = ERB::Compiler.new('<>')
+  #   compiler.pre_cmd    = ["_erbout=+''"]
+  #   compiler.put_cmd    = "_erbout.<<"
+  #   compiler.insert_cmd = "_erbout.<<"
+  #   compiler.post_cmd   = ["_erbout"]
+  #
+  #   code, enc = compiler.compile("Got <%= obj %>!\n")
+  #   puts code
+  #
+  # <i>Generates</i>:
+  #
+  #   #coding:UTF-8
+  #   _erbout=+''; _erbout.<< "Got ".freeze; _erbout.<<(( obj ).to_s); _erbout.<< "!\n".freeze; _erbout
+  #
+  # By default the output is sent to the print method.  For example:
+  #
+  #   compiler = ERB::Compiler.new('<>')
+  #   code, enc = compiler.compile("Got <%= obj %>!\n")
+  #   puts code
+  #
+  # <i>Generates</i>:
+  #
+  #   #coding:UTF-8
+  #   print "Got ".freeze; print(( obj ).to_s); print "!\n".freeze
+  #
+  # == Evaluation
+  #
+  # The compiled code can be used in any context where the names in the code
+  # correctly resolve. Using the last example, each of these print 'Got It!'
+  #
+  # Evaluate using a variable:
+  #
+  #   obj = 'It'
+  #   eval code
+  #
+  # Evaluate using an input:
+  #
+  #   mod = Module.new
+  #   mod.module_eval %{
+  #     def get(obj)
+  #       #{code}
+  #     end
+  #   }
+  #   extend mod
+  #   get('It')
+  #
+  # Evaluate using an accessor:
+  #
+  #   klass = Class.new Object
+  #   klass.class_eval %{
+  #     attr_accessor :obj
+  #     def initialize(obj)
+  #       @obj = obj

-# ERB::Compiler
-#
-# Compiles ERB templates into Ruby code; the compiled code produces the
-# template result when evaluated. ERB::Compiler provides hooks to define how
-# generated output is handled.
-#
-# Internally ERB does something like this to generate the code returned by
-# ERB#src:
-#
-#   compiler = ERB::Compiler.new('<>')
-#   compiler.pre_cmd    = ["_erbout=+''"]
-#   compiler.put_cmd    = "_erbout.<<"
-#   compiler.insert_cmd = "_erbout.<<"
-#   compiler.post_cmd   = ["_erbout"]
-#
-#   code, enc = compiler.compile("Got <%= obj %>!\n")
-#   puts code
-#
-# <i>Generates</i>:
-#
-#   #coding:UTF-8
-#   _erbout=+''; _erbout.<< "Got ".freeze; _erbout.<<(( obj ).to_s); _erbout.<< "!\n".freeze; _erbout
-#
-# By default the output is sent to the print method.  For example:
-#
-#   compiler = ERB::Compiler.new('<>')
-#   code, enc = compiler.compile("Got <%= obj %>!\n")
-#   puts code
-#
-# <i>Generates</i>:
-#
-#   #coding:UTF-8
-#   print "Got ".freeze; print(( obj ).to_s); print "!\n".freeze
-#
-# == Evaluation
-#
-# The compiled code can be used in any context where the names in the code
-# correctly resolve. Using the last example, each of these print 'Got It!'
-#
-# Evaluate using a variable:
-#
-#   obj = 'It'
-#   eval code
-#
-# Evaluate using an input:
-#
-#   mod = Module.new
-#   mod.module_eval %{
-#     def get(obj)
-#       #{code}
-#     end
-#   }
-#   extend mod
-#   get('It')
-#
-# Evaluate using an accessor:
-#
-#   klass = Class.new Object
-#   klass.class_eval %{
-#     attr_accessor :obj
-#     def initialize(obj)
-#       @obj = obj
-#     end
-#     def get_it
-#       #{code}
-#     end
-#   }
-#   klass.new('It').get_it
-#

 #
-# - ::pwd, ::getwd: Returns the path to the working directory.
-# - ::uptodate?: Returns whether a given entry is newer than given other entries.
+# Each method documents the options that it honours. See also ::commands,
+# ::options and ::options_of methods to introspect which command have which
+# options.
 #
-# === Setting
+# All methods that have the concept of a "source" file or directory can take
+# either one file or a list of files in that argument.  See the method
+# documentation for examples.
 #
-# - ::cd, ::chdir: Sets the working directory.

 #
-# - ::compare_file, ::cmp, ::identical?: Returns whether two entries are identical.
-# - ::compare_stream: Returns whether two streams are identical.
+# == module FileUtils::Verbose
 #
-# === Copying
+# This module has all methods of FileUtils module, but it outputs messages
+# before acting.  This equates to passing the <tt>:verbose</tt> flag to methods
+# in FileUtils.
 #
-# - ::copy_entry: Recursively copies an entry.
-# - ::copy_file: Copies an entry.
-# - ::copy_stream: Copies a stream.
-# - ::cp, ::copy: Copies files.
-# - ::cp_lr: Recursively creates hard links.
-# - ::cp_r: Recursively copies files, retaining mode, owner, and group.
-# - ::install: Recursively copies files, optionally setting mode,
-#   owner, and group.
+# == module FileUtils::NoWrite
 #
-# === Moving
+# This module has all methods of FileUtils module, but never changes
+# files/directories.  This equates to passing the <tt>:noop</tt> flag to methods
+# in FileUtils.
 #
-# - ::mv, ::move: Moves entries.
+# == module FileUtils::DryRun
 #
-# === Options
-#
-# - ::collect_method: Returns the names of methods that accept a given option.
-# - ::commands: Returns the names of methods that accept options.
-# - ::have_option?: Returns whether a given method accepts a given option.
-# - ::options: Returns all option names.
-# - ::options_of: Returns the names of the options for a given method.
-#
-# == Path Arguments
-#
-# Some methods in \FileUtils accept _path_ arguments,
-# which are interpreted as paths to filesystem entries:
-#
-# - If the argument is a string, that value is the path.
-# - If the argument has method +:to_path+, it is converted via that method.
-# - If the argument has method +:to_str+, it is converted via that method.
-#
-# == About the Examples
-#
-# Some examples here involve trees of file entries.
-# For these, we sometimes display trees using the
-# {tree command-line utility}[https://en.wikipedia.org/wiki/Tree_(command)],
-# which is a recursive directory-listing utility that produces
-# a depth-indented listing of files and directories.
-#

-# == Avoiding the TOCTTOU Vulnerability
-#
-# For certain methods that recursively remove entries,
-# there is a potential vulnerability called the
-# {Time-of-check to time-of-use}[https://en.wikipedia.org/wiki/Time-of-check_to_time-of-use],
-# or TOCTTOU, vulnerability that can exist when:
-#
-# - An ancestor directory of the entry at the target path is world writable;
-#   such directories include <tt>/tmp</tt>.
-# - The directory tree at the target path includes:
-#
-#   - A world-writable descendant directory.
-#   - A symbolic link.
-#
-# To avoid that vulnerability, you can use this method to remove entries:
-#
-# - FileUtils.remove_entry_secure: removes recursively
-#   if the target path points to a directory.
-#
-# Also available are these methods,
-# each of which calls \FileUtils.remove_entry_secure:
-#
-# - FileUtils.rm_r with keyword argument <tt>secure: true</tt>.
-# - FileUtils.rm_rf with keyword argument <tt>secure: true</tt>.
-#
-# Finally, this method for moving entries calls \FileUtils.remove_entry_secure
-# if the source and destination are on different file systems
-# (which means that the "move" is really a copy and remove):
-#
-# - FileUtils.mv with keyword argument <tt>secure: true</tt>.
-#
-# \Method \FileUtils.remove_entry_secure removes securely
-# by applying a special pre-process:
-#
-# - If the target path points to a directory, this method uses methods
-#   {File#chown}[rdoc-ref:File#chown]
-#   and {File#chmod}[rdoc-ref:File#chmod]
-#   in removing directories.
-# - The owner of the target directory should be either the current process
-#   or the super user (root).
-#
-# WARNING: You must ensure that *ALL* parent directories cannot be
-# moved by other untrusted users.  For example, parent directories
-# should not be owned by untrusted users, and should not be world
-# writable except when the sticky bit is set.
-#
-# For details of this security vulnerability, see Perl cases:
-#
-# - {CVE-2005-0448}[https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0448].

 #
 # You may redistribute and/or modify this library under the same license
 # terms as Ruby.
-
-# \Class \GetoptLong provides parsing both for options
-# and for regular arguments.
-#
-# Using \GetoptLong, you can define options for your program.
-# The program can then capture and respond to whatever options
-# are included in the command that executes the program.
-#
-# A simple example: file <tt>simple.rb</tt>:
-#
-#   :include: ../sample/getoptlong/simple.rb
-#
-# If you are somewhat familiar with options,
-# you may want to skip to this
-# {full example}[#class-GetoptLong-label-Full+Example].
-#
-# == Options
-#
-# A \GetoptLong option has:
-#
-# - A string <em>option name</em>.
-# - Zero or more string <em>aliases</em> for the name.
-# - An <em>option type</em>.
-#
-# Options may be defined by calling singleton method GetoptLong.new,
-# which returns a new \GetoptLong object.
-# Options may then be processed by calling other methods
-# such as GetoptLong#each.
-#
-# === Option Name and Aliases
-#
-# In the array that defines an option,
-# the first element is the string option name.
-# Often the name takes the 'long' form, beginning with two hyphens.
-#
-# The option name may have any number of aliases,
-# which are defined by additional string elements.
-#
-# The name and each alias must be of one of two forms:
-#
-# - Two hyphens, followed by one or more letters.
-# - One hyphen, followed by a single letter.
-#
-# File <tt>aliases.rb</tt>:
-#
-#   :include: ../sample/getoptlong/aliases.rb
-#
-# An option may be cited by its name,
-# or by any of its aliases;
-# the parsed option always reports the name, not an alias:
-#
-#   $ ruby aliases.rb -a -p --xxx --aaa -x
-#
-# Output:
-#
-#   ["--xxx", ""]
-#   ["--xxx", ""]
-#   ["--xxx", ""]
-#   ["--xxx", ""]
-#   ["--xxx", ""]
-#
-#
-# An option may also be cited by an abbreviation of its name or any alias,
-# as long as that abbreviation is unique among the options.

-# Command line:

-#
-# Output:
-#
-#   ["--xxx", ""]
-#   ["--xxx", ""]
-#   ["--xyz", ""]
-#   ["--xyz", ""]
-#
-# This command line raises GetoptLong::AmbiguousOption:
-#
-#   $ ruby abbrev.rb --x
-#
-# === Repetition
-#
-# An option may be cited more than once:
-#
-#   $ ruby abbrev.rb --xxx --xyz --xxx --xyz
-#
-# Output:
-#
-#   ["--xxx", ""]
-#   ["--xyz", ""]
-#   ["--xxx", ""]
-#   ["--xyz", ""]
-#
-# === Treating Remaining Options as Arguments
-#
-# A option-like token that appears
-# anywhere after the token <tt>--</tt> is treated as an ordinary argument,
-# and is not processed as an option:
-#
-#   $ ruby abbrev.rb --xxx --xyz -- --xxx --xyz
-#
-# Output:
-#
-#   ["--xxx", ""]
-#   ["--xyz", ""]
-#
-# === Option Types
-#
-# Each option definition includes an option type,
-# which controls whether the option takes an argument.
-#
-# File <tt>types.rb</tt>:
-#
-#   :include: ../sample/getoptlong/types.rb
-#
-# Note that an option type has to do with the <em>option argument</em>
-# (whether it is required, optional, or forbidden),
-# not with whether the option itself is required.
-#
-# ==== Option with Required Argument
-#
-# An option of type <tt>GetoptLong::REQUIRED_ARGUMENT</tt>
-# must be followed by an argument, which is associated with that option:
-#
-#   $ ruby types.rb --xxx foo
-#
-# Output:
-#
-#   ["--xxx", "foo"]
-#
-# If the option is not last, its argument is whatever follows it
-# (even if the argument looks like another option):
-#
-#   $ ruby types.rb --xxx --yyy
-#
-# Output:
-#
-#   ["--xxx", "--yyy"]
-#
-# If the option is last, an exception is raised:
-#
-#   $ ruby types.rb
-#   # Raises GetoptLong::MissingArgument
-#
-# ==== Option with Optional Argument
-#
-# An option of type <tt>GetoptLong::OPTIONAL_ARGUMENT</tt>
-# may be followed by an argument, which if given is associated with that option.
-#
-# If the option is last, it does not have an argument:
-#
-#   $ ruby types.rb --yyy
-#
-# Output:
-#
-#   ["--yyy", ""]
-#
-# If the option is followed by another option, it does not have an argument:
-#
-#   $ ruby types.rb --yyy --zzz
-#
-# Output:
-#
-#   ["--yyy", ""]
-#   ["--zzz", ""]
-#
-# Otherwise the option is followed by its argument, which is associated
-# with that option:
-#
-#   $ ruby types.rb --yyy foo
-#
-# Output:
-#
-#   ["--yyy", "foo"]
-#
-# ==== Option with No Argument
-#
-# An option of type <tt>GetoptLong::NO_ARGUMENT</tt> takes no argument:
-#
-#   ruby types.rb --zzz foo
-#
-# Output:
-#
-#   ["--zzz", ""]
-#
-# === ARGV
-#
-# You can process options either with method #each and a block,
-# or with method #get.
-#
-# During processing, each found option is removed, along with its argument
-# if there is one.
-# After processing, each remaining element was neither an option
-# nor the argument for an option.
-#
-# File <tt>argv.rb</tt>:
-#
-#   :include: ../sample/getoptlong/argv.rb
 #
-# Command line:
+# See GetoptLong for documentation.
 #
-#   $ ruby argv.rb --xxx Foo --yyy Bar Baz --zzz Bat Bam
-#
-# Output:
-#
-#   Original ARGV: ["--xxx", "Foo", "--yyy", "Bar", "Baz", "--zzz", "Bat", "Bam"]
-#   ["--xxx", "Foo"]
-#   ["--yyy", "Bar"]
-#   ["--zzz", ""]
-#   Remaining ARGV: ["Baz", "Bat", "Bam"]
-#
-# === Ordering
-#
-# There are three settings that control the way the options
-# are interpreted:
-#
-# - +PERMUTE+.
-# - +REQUIRE_ORDER+.
-# - +RETURN_IN_ORDER+.
-#
-# The initial setting for a new \GetoptLong object is +REQUIRE_ORDER+
-# if environment variable +POSIXLY_CORRECT+ is defined, +PERMUTE+ otherwise.
-#
-# ==== PERMUTE Ordering
-#
-# In the +PERMUTE+ ordering, options and other, non-option,
-# arguments may appear in any order and any mixture.
-#
-# File <tt>permute.rb</tt>:
-#
-#   :include: ../sample/getoptlong/permute.rb
-#
-# Command line:
-#
-#   $ ruby permute.rb Foo --zzz Bar --xxx Baz --yyy Bat Bam --xxx Bag Bah
-#
-# Output:
-#
-#   Original ARGV: ["Foo", "--zzz", "Bar", "--xxx", "Baz", "--yyy", "Bat", "Bam", "--xxx", "Bag", "Bah"]
-#   ["--zzz", ""]
-#   ["--xxx", "Baz"]
-#   ["--yyy", "Bat"]
-#   ["--xxx", "Bag"]
-#   Remaining ARGV: ["Foo", "Bar", "Bam", "Bah"]
-#
-# ==== REQUIRE_ORDER Ordering
-#
-# In the +REQUIRE_ORDER+ ordering, all options precede all non-options;
-# that is, each word after the first non-option word
-# is treated as a non-option word (even if it begins with a hyphen).
-#
-# File <tt>require_order.rb</tt>:
-#
-#   :include: ../sample/getoptlong/require_order.rb
-#
-# Command line:
-#
-#   $ ruby require_order.rb --xxx Foo Bar --xxx Baz --yyy Bat -zzz
-#
-# Output:
-#
-#   Original ARGV: ["--xxx", "Foo", "Bar", "--xxx", "Baz", "--yyy", "Bat", "-zzz"]
-#   ["--xxx", "Foo"]
-#   Remaining ARGV: ["Bar", "--xxx", "Baz", "--yyy", "Bat", "-zzz"]
-#
-# ==== RETURN_IN_ORDER Ordering
-#
-# In the +RETURN_IN_ORDER+ ordering, every word is treated as an option.
-# A word that begins with a hyphen (or two) is treated in the usual way;
-# a word +word+ that does not so begin is treated as an option
-# whose name is an empty string, and whose value is +word+.
-#
-# File <tt>return_in_order.rb</tt>:
-#
-#   :include: ../sample/getoptlong/return_in_order.rb
-#
-# Command line:
-#
-#   $ ruby return_in_order.rb Foo --xxx Bar Baz --zzz Bat Bam
-#
-# Output:
-#
-#   Original ARGV: ["Foo", "--xxx", "Bar", "Baz", "--zzz", "Bat", "Bam"]
-#   ["", "Foo"]
-#   ["--xxx", "Bar"]
-#   ["", "Baz"]
-#   ["--zzz", ""]
-#   ["", "Bat"]
-#   ["", "Bam"]
-#   Remaining ARGV: []
-#
-# === Full Example

-# == \IRB
-#
-# \Module \IRB ("Interactive Ruby") provides a shell-like interface
-# that supports user interaction with the Ruby interpreter.
-#
-# It operates as a <i>read-eval-print loop</i>
-# ({REPL}[https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop])
-# that:
-#
-# - <b>_Reads_</b> each character as you type.
-#   You can modify the \IRB context to change the way input works.
-#   See {Input}[rdoc-ref:IRB@Input].
-# - <b>_Evaluates_</b> the code each time it has read a syntactically complete passage.
-# - <b>_Prints_</b> after evaluating.
-#   You can modify the \IRB context to change the way output works.
-#   See {Output}[rdoc-ref:IRB@Output].
-#
-# Example:
-#
-#   $ irb
-#   irb(main):001> File.basename(Dir.pwd)
-#   => "irb"
-#   irb(main):002> Dir.entries('.').size
-#   => 25
-#   irb(main):003* Dir.entries('.').select do |entry|
-#   irb(main):004*   entry.start_with?('R')
-#   irb(main):005> end
-#   => ["README.md", "Rakefile"]
-#
-# The typed input may also include
-# {\IRB-specific commands}[rdoc-ref:IRB@IRB-Specific+Commands].
-#
-# As seen above, you can start \IRB by using the shell command +irb+.
-#
-# You can stop an \IRB session by typing command +exit+:
-#
-#   irb(main):006> exit
-#   $
-#
-# At that point, \IRB calls any hooks found in array <tt>IRB.conf[:AT_EXIT]</tt>,
-# then exits.
-#
-# == Startup
-#
-# At startup, \IRB:
-#
-# 1. Interprets (as Ruby code) the content of the
-#    {configuration file}[rdoc-ref:IRB@Configuration+File] (if given).
-# 1. Constructs the initial session context
-#    from {hash IRB.conf}[rdoc-ref:IRB@Hash+IRB.conf] and from default values;
-#    the hash content may have been affected
-#    by {command-line options}[rdoc-ref:IB@Command-Line+Options],
-#    and by direct assignments in the configuration file.
-# 1. Assigns the context to variable +conf+.
-# 1. Assigns command-line arguments to variable <tt>ARGV</tt>.
-# 1. Prints the {prompt}[rdoc-ref:IRB@Prompt+and+Return+Formats].
-# 1. Puts the content of the
-#    {initialization script}[rdoc-ref:IRB@Initialization+Script]
-#    onto the \IRB shell, just as if it were user-typed commands.
-#
-# === The Command Line
-#
-# On the command line, all options precede all arguments;
-# the first item that is not recognized as an option is treated as an argument,
-# as are all items that follow.
-#
-# ==== Command-Line Options
-#
-# Many command-line options affect entries in hash <tt>IRB.conf</tt>,
-# which in turn affect the initial configuration of the \IRB session.
-#
-# Details of the options are described in the relevant subsections below.
-#
-# A cursory list of the \IRB command-line options
-# may be seen in the {help message}[https://raw.githubusercontent.com/ruby/irb/master/lib/irb/lc/help-message],
-# which is also displayed if you use command-line option <tt>--help</tt>.
-#
-# If you are interested in a specific option, consult the
-# {index}[rdoc-ref:doc/irb/indexes.md@Index+of+Command-Line+Options].
-#
-# ==== Command-Line Arguments
-#
-# Command-line arguments are passed to \IRB in array +ARGV+:
-#
-#   $ irb --noscript Foo Bar Baz
-#   irb(main):001> ARGV
-#   => ["Foo", "Bar", "Baz"]
-#   irb(main):002> exit
-#   $
-#
-# Command-line option <tt>--</tt> causes everything that follows
-# to be treated as arguments, even those that look like options:
-#
-#   $ irb --noscript -- --noscript -- Foo Bar Baz
-#   irb(main):001> ARGV
-#   => ["--noscript", "--", "Foo", "Bar", "Baz"]
-#   irb(main):002> exit
-#   $
-#
-# === Configuration File
-#
-# You can initialize \IRB via a <i>configuration file</i>.
-#
-# If command-line option <tt>-f</tt> is given,
-# no configuration file is looked for.
-#
-# Otherwise, \IRB reads and interprets a configuration file
-# if one is available.
-#
-# The configuration file can contain any Ruby code, and can usefully include
-# user code that:
-#
-# - Can then be debugged in \IRB.
-# - Configures \IRB itself.
-# - Requires or loads files.
-#
-# The path to the configuration file is the first found among:
-#
-# - The value of variable <tt>$IRBRC</tt>, if defined.
-# - The value of variable <tt>$XDG_CONFIG_HOME/irb/irbrc</tt>, if defined.
-# - File <tt>$HOME/.irbrc</tt>, if it exists.
-# - File <tt>$HOME/.config/irb/irbrc</tt>, if it exists.
-# - File +.config/irb/irbrc+ in the current directory, if it exists.
-# - File +.irbrc+ in the current directory, if it exists.
-# - File +irb.rc+ in the current directory, if it exists.
-# - File +_irbrc+ in the current directory, if it exists.
-# - File <tt>$irbrc</tt> in the current directory, if it exists.
-#
-# If the search fails, there is no configuration file.
-#
-# If the search succeeds, the configuration file is read as Ruby code,
-# and so can contain any Ruby programming you like.
-#
-# \Method <tt>conf.rc?</tt> returns +true+ if a configuration file was read,
-# +false+ otherwise.
-# \Hash entry <tt>IRB.conf[:RC]</tt> also contains that value.
-#
-# === \Hash <tt>IRB.conf</tt>
-#
-# The initial entries in hash <tt>IRB.conf</tt> are determined by:
-#
-# - Default values.
-# - Command-line options, which may override defaults.
-# - Direct assignments in the configuration file.
-#
-# You can see the hash by typing <tt>IRB.conf</tt>.
-#
-# Details of the entries' meanings are described in the relevant subsections below.
-#
-# If you are interested in a specific entry, consult the
-# {index}[rdoc-ref:doc/irb/indexes.md@Index+of+IRB.conf+Entries].
-#
-# === Notes on Initialization Precedence
-#
-# - Any conflict between an entry in hash <tt>IRB.conf</tt> and a command-line option
-#   is resolved in favor of the hash entry.
-# - \Hash <tt>IRB.conf</tt> affects the context only once,
-#   when the configuration file is interpreted;
-#   any subsequent changes to it do not affect the context
-#   and are therefore essentially meaningless.
-#
-# === Initialization Script
-#
-# By default, the first command-line argument (after any options)
-# is the path to a Ruby initialization script.
-#
-# \IRB reads the initialization script and puts its content onto the \IRB shell,
-# just as if it were user-typed commands.
-#
-# Command-line option <tt>--noscript</tt> causes the first command-line argument
-# to be treated as an ordinary argument (instead of an initialization script);
-# <tt>--script</tt> is the default.
-#
-# == Input
-#
-# This section describes the features that allow you to change
-# the way \IRB input works;
-# see also {Input and Output}[rdoc-ref:IRB@Input+and+Output].
-#
-# === Input Command History
-#
-# By default, \IRB stores a history of up to 1000 input commands
-# in file <tt>~/.irb_history</tt>
-# (or, if a {configuration file}[rdoc-ref:IRB@Configuration+File]
-# is found, in file +.irb_history+
-# inin the same directory as that file).
-#
-# A new \IRB session creates the history file if it does not exist,
-# and appends to the file if it does exist.
-#
-# You can change the filepath by adding to your configuration file:
-# <tt>IRB.conf[:HISTORY_FILE] = _filepath_</tt>,
-# where _filepath_ is a string filepath.
-#
-# During the session, method <tt>conf.history_file</tt> returns the filepath,
-# and method <tt>conf.history_file = <i>new_filepath</i></tt>
-# copies the history to the file at <i>new_filepath</i>,
-# which becomes the history file for the session.
-#
-# You can change the number of commands saved by adding to your configuration file:
-# <tt>IRB.conf[:SAVE_HISTORY] = _n_</tt>,
-# where _n_ is one of:
-#
-# - Positive integer: the number of commands to be saved,
-# - Zero: all commands are to be saved.
-# - +nil+: no commands are to be saved,.
-#
-# During the session, you can use
-# methods <tt>conf.save_history</tt> or <tt>conf.save_history=</tt>
-# to retrieve or change the count.
-#
-# === Command Aliases
-#
-# By default, \IRB defines several command aliases:
-#
-#   irb(main):001> conf.command_aliases
-#   => {:"$"=>:show_source, :"@"=>:whereami}
-#
-# You can change the initial aliases in the configuration file with:
-#
-#   IRB.conf[:COMMAND_ALIASES] = {foo: :show_source, bar: :whereami}
-#
-# You can replace the current aliases at any time
-# with configuration method <tt>conf.command_aliases=</tt>;
-# Because <tt>conf.command_aliases</tt> is a hash,
-# you can modify it.
-#
-# === End-of-File
-#
-# By default, <tt>IRB.conf[:IGNORE_EOF]</tt> is +false+,
-# which means that typing the end-of-file character <tt>Ctrl-D</tt>
-# causes the session to exit.
-#
-# You can reverse that behavior by adding <tt>IRB.conf[:IGNORE_EOF] = true</tt>
-# to the configuration file.
-#
-# During the session, method <tt>conf.ignore_eof?</tt> returns the setting,
-# and method <tt>conf.ignore_eof = _boolean_</tt> sets it.
-#
-# === SIGINT
-#
-# By default, <tt>IRB.conf[:IGNORE_SIGINT]</tt> is +true+,
-# which means that typing the interrupt character <tt>Ctrl-C</tt>
-# causes the session to exit.
-#
-# You can reverse that behavior by adding <tt>IRB.conf[:IGNORE_SIGING] = false</tt>
-# to the configuration file.
-#
-# During the session, method <tt>conf.ignore_siging?</tt> returns the setting,
-# and method <tt>conf.ignore_sigint = _boolean_</tt> sets it.
-#
-# === Automatic Completion
-#
-# By default, \IRB enables
-# {automatic completion}[https://en.wikipedia.org/wiki/Autocomplete#In_command-line_interpreters]:
-#
-# You can disable it by either of these:
-#
-# - Adding <tt>IRB.conf[:USE_AUTOCOMPLETE] = false</tt> to the configuration file.
-# - Giving command-line option <tt>--noautocomplete</tt>
-#   (<tt>--autocomplete</tt> is the default).
-#
-# \Method <tt>conf.use_autocomplete?</tt> returns +true+
-# if automatic completion is enabled, +false+ otherwise.
-#
-# The setting may not be changed during the session.
-#
-# === Automatic Indentation
-#
-# By default, \IRB automatically indents lines of code to show structure
-# (e.g., it indent the contents of a block).
-#
-# The current setting is returned
-# by the configuration method <tt>conf.auto_indent_mode</tt>.
-#
-# The default initial setting is +true+:
-#
-#   irb(main):001> conf.auto_indent_mode
-#   => true
-#   irb(main):002* Dir.entries('.').select do |entry|
-#   irb(main):003*   entry.start_with?('R')
-#   irb(main):004> end
-#   => ["README.md", "Rakefile"]
-#
-# You can change the initial setting in the
-# configuration file with:
-#
-#   IRB.conf[:AUTO_INDENT] = false
-#
-# Note that the _current_ setting <i>may not</i> be changed in the \IRB session.
-#
-# === Input \Method
-#
-# The \IRB input method determines how command input is to be read;
-# by default, the input method for a session is IRB::RelineInputMethod.
-#
-# You can set the input method by:
-#
-# - Adding to the configuration file:
-#
-#   - <tt>IRB.conf[:USE_SINGLELINE] = true</tt>
-#     or <tt>IRB.conf[:USE_MULTILINE]= false</tt>
-#     sets the input method to IRB::ReadlineInputMethod.
-#   - <tt>IRB.conf[:USE_SINGLELINE] = false</tt>
-#     or <tt>IRB.conf[:USE_MULTILINE] = true</tt>
-#     sets the input method to IRB::RelineInputMethod.
-#
-# - Giving command-line options:
-#
-#   - <tt>--singleline</tt>
-#     or <tt>--nomultiline</tt>
-#     sets the input method to IRB::ReadlineInputMethod.
-#   - <tt>--nosingleline</tt>
-#     or <tt>--multiline/tt>
-#     sets the input method to IRB::RelineInputMethod.
-#
-# \Method <tt>conf.use_multiline?</tt>
-# and its synonym <tt>conf.use_reline</tt> return:
-#
-# - +true+ if option <tt>--multiline</tt> was given.
-# - +false+ if option <tt>--nomultiline</tt> was given.
-# - +nil+ if neither was given.
-#
-# \Method <tt>conf.use_singleline?</tt>
-# and its synonym <tt>conf.use_readline</tt> return:
-#
-# - +true+ if option <tt>--singleline</tt> was given.
-# - +false+ if option <tt>--nosingleline</tt> was given.
-# - +nil+ if neither was given.
-#
-# == Output
-#
-# This section describes the features that allow you to change
-# the way \IRB output works;
-# see also {Input and Output}[rdoc-ref:IRB@Input+and+Output].
-#
-# === Return-Value Printing (Echoing)
-#
-# By default, \IRB prints (echoes) the values returned by all input commands.
-#
-# You can change the initial behavior and suppress all echoing by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:ECHO] = false</tt>.
-#   (The default value for this entry is +niL+, which means the same as +true+.)
-# - Giving command-line option <tt>--noecho</tt>.
-#   (The default is <tt>--echo</tt>.)
-#
-# During the session, you can change the current setting
-# with configuration method <tt>conf.echo=</tt> (set to +true+ or +false+).
-#
-# As stated above, by default \IRB prints the values returned by all input commands;
-# but \IRB offers special treatment for values returned by assignment statements,
-# which may be:
-#
-# - Printed with truncation (to fit on a single line of output),
-#   which is the default;
-#   an ellipsis (<tt>...</tt> is suffixed, to indicate the truncation):
-#
-#     irb(main):001> x = 'abc' * 100
-# => "abcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabc...
-#
-# - Printed in full (regardless of the length).
-# - Suppressed (not printed at all)
-#
-# You can change the initial behavior by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:ECHO_ON_ASSIGNMENT] = false</tt>.
-#   (The default value for this entry is +niL+, which means the same as +:truncate+.)
-# - Giving command-line option <tt>--noecho-on-assignment</tt>
-#   or <tt>--echo-on-assignment</tt>.
-#   (The default is <tt>--truncate-echo-on-assigment</tt>.)
-#
-# During the session, you can change the current setting
-# with configuration method <tt>conf.echo_on_assignment=</tt>
-# (set to +true+, +false+, or +:truncate+).
-#
-# By default, \IRB formats returned values by calling method +inspect+.
-#
-# You can change the initial behavior by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:INSPECT_MODE] = false</tt>.
-#   (The default value for this entry is +true+.)
-# - Giving command-line option <tt>--noinspect</tt>.
-#   (The default is <tt>--inspect</tt>.)
-#
-# During the session, you can change the setting using method <tt>conf.inspect_mode=</tt>.
-#
-# === Multiline Output
-#
-# By default, \IRB prefixes a newline to a multiline response.
-#
-# You can change the initial default value by adding to the configuation file:
-#
-#   IRB.conf[:NEWLINE_BEFORE_MULTILINE_OUTPUT] = false
-#
-# During a session, you can retrieve or set the value using
-# methods <tt>conf.newline_before_multiline_output?</tt>
-# and <tt>conf.newline_before_multiline_output=</tt>.
-#
-# Examples:
-#
-#   irb(main):001> conf.inspect_mode = false
-#   => false
-#   irb(main):002> "foo\nbar"
-#   =>
-#   foo
-#   bar
-#   irb(main):003> conf.newline_before_multiline_output = false
-#   => false
-#   irb(main):004> "foo\nbar"
-#   => foo
-#   bar
-#
-# === Evaluation History
-#
-# By default, \IRB saves no history of evaluations (returned values),
-# and the related methods <tt>conf.eval_history</tt>, <tt>_</tt>,
-# and <tt>__</tt> are undefined.
-#
-# You can turn on that history, and set the maximum number of evaluations to be stored:
-#
-# - In the configuration file: add <tt>IRB.conf[:EVAL_HISTORY] = _n_</tt>.
-#   (Examples below assume that we've added <tt>IRB.conf[:EVAL_HISTORY] = 5</tt>.)
-# - In the session (at any time): <tt>conf.eval_history = _n_</tt>.
-#
-# If +n+ is zero, all evaluation history is stored.
-#
-# Doing either of the above:
-#
-# - Sets the maximum size of the evaluation history;
-#   defines method <tt>conf.eval_history</tt>,
-#   which returns the maximum size +n+ of the evaluation history:
-#
-#     irb(main):001> conf.eval_history = 5
-#     => 5
-#     irb(main):002> conf.eval_history
-#     => 5
-#
-# - Defines variable <tt>_</tt>, which contains the most recent evaluation,
-#   or +nil+ if none; same as method <tt>conf.last_value</tt>:
-#
-#     irb(main):003> _
-#     => 5
-#     irb(main):004> :foo
-#     => :foo
-#     irb(main):005> :bar
-#     => :bar
-#     irb(main):006> _
-#     => :bar
-#     irb(main):007> _
-#     => :bar
-#
-# - Defines variable <tt>__</tt>:
-#
-#   - <tt>__</tt> unadorned: contains all evaluation history:
-#
-#       irb(main):008> :foo
-#       => :foo
-#       irb(main):009> :bar
-#       => :bar
-#       irb(main):010> :baz
-#       => :baz
-#       irb(main):011> :bat
-#       => :bat
-#       irb(main):012> :bam
-#       => :bam
-#       irb(main):013> __
-#       =>
-#       9 :bar
-#       10 :baz
-#       11 :bat
-#       12 :bam
-#       irb(main):014> __
-#       =>
-#       10 :baz
-#       11 :bat
-#       12 :bam
-#       13 ...self-history...
-#
-#     Note that when the evaluation is multiline, it is displayed differently.
-#
-#   - <tt>__[</tt>_m_<tt>]</tt>:
-#
-#     - Positive _m_:  contains the evaluation for the given line number,
-#       or +nil+ if that line number is not in the evaluation history:
-#
-#         irb(main):015> __[12]
-#         => :bam
-#         irb(main):016> __[1]
-#         => nil
-#
-#     - Negative _m_: contains the +mth+-from-end evaluation,
-#       or +nil+ if that evaluation is not in the evaluation history:
-#
-#         irb(main):017> __[-3]
-#         => :bam
-#         irb(main):018> __[-13]
-#         => nil
-#
-#     - Zero _m_: contains +nil+:
-#
-#         irb(main):019> __[0]
-#         => nil
-#
-# === Prompt and Return Formats
-#
-# By default, \IRB uses the prompt and return value formats
-# defined in its +:DEFAULT+ prompt mode.
-#
-# ==== The Default Prompt and Return Format
-#
-# The default prompt and return values look like this:
-#
-#   irb(main):001> 1 + 1
-#   => 2
-#   irb(main):002> 2 + 2
-#   => 4
-#
-# The prompt includes:
-#
-# - The name of the running program (<tt>irb</tt>);
-#   see {IRB Name}[rdoc-ref:IRB@IRB+Name].
-# - The name of the current session (<tt>main</tt>);
-#   See {IRB Sessions}[rdoc-ref:IRB@IRB+Sessions].
-# - A 3-digit line number (1-based).
-#
-# The default prompt actually defines three formats:
-#
-# - One for most situations (as above):
-#
-#     irb(main):003> Dir
-#     => Dir
-#
-# - One for when the typed command is a statement continuation (adds trailing asterisk):
-#
-#     irb(main):004* Dir.
-#
-# - One for when the typed command is a string continuation (adds trailing single-quote):
-#
-#     irb(main):005' Dir.entries('.
-#
-# You can see the prompt change as you type the characters in the following:
-#
-#     irb(main):001* Dir.entries('.').select do |entry|
-#     irb(main):002*   entry.start_with?('R')
-#     irb(main):003> end
-#     => ["README.md", "Rakefile"]
-#
-# ==== Pre-Defined Prompts
-#
-# \IRB has several pre-defined prompts, stored in hash <tt>IRB.conf[:PROMPT]</tt>:
-#
-#   irb(main):001> IRB.conf[:PROMPT].keys
-#   => [:NULL, :DEFAULT, :CLASSIC, :SIMPLE, :INF_RUBY, :XMP]
-#
-# To see the full data for these, type <tt>IRB.conf[:PROMPT]</tt>.
-#
-# Most of these prompt definitions include specifiers that represent
-# values like the \IRB name, session name, and line number;
-# see {Prompt Specifiers}[rdoc-ref:IRB@Prompt+Specifiers].
-#
-# You can change the initial prompt and return format by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:PROMPT] = _mode_</tt>
-#   where _mode_ is the symbol name of a prompt mode.
-# - Giving a command-line option:
-#
-#   - <tt>--prompt _mode_</tt>: sets the prompt mode to _mode_.
-#     where _mode_ is the symbol name of a prompt mode.
-#   - <tt>--simple-prompt</tt> or <tt>--sample-book-mode</tt>:
-#     sets the prompt mode to +:SIMPLE+.
-#   - <tt>--inf-ruby-mode</tt>: sets the prompt mode to +:INF_RUBY+
-#     and suppresses both <tt>--multiline</tt> and <tt>--singleline</tt>.
-#   - <tt>--noprompt</tt>: suppresses prompting; does not affect echoing.
-#
-# You can retrieve or set the current prompt mode with methods
-#
-# <tt>conf.prompt_mode</tt> and <tt>conf.prompt_mode=</tt>.
-#
-# If you're interested in prompts and return formats other than the defaults,
-# you might experiment by trying some of the others.
-#
-# ==== Custom Prompts
-#
-# You can also define custom prompts and return formats,
-# which may be done either in an \IRB session or in the configuration file.
-#
-# A prompt in \IRB actually defines three prompts, as seen above.
-# For simple custom data, we'll make all three the same:
-#
-#   irb(main):001* IRB.conf[:PROMPT][:MY_PROMPT] = {
-#   irb(main):002*   PROMPT_I: ': ',
-#   irb(main):003*   PROMPT_C: ': ',
-#   irb(main):004*   PROMPT_S: ': ',
-#   irb(main):005*   RETURN: '=> '
-#   irb(main):006> }
-#   => {:PROMPT_I=>": ", :PROMPT_C=>": ", :PROMPT_S=>": ", :RETURN=>"=> "}
-#
-# If you define the custom prompt in the configuration file,
-# you can also make it the current prompt by adding:
-#
-#   IRB.conf[:PROMPT_MODE] = :MY_PROMPT
-#
-# Regardless of where it's defined, you can make it the current prompt in a session:
-#
-#   conf.prompt_mode = :MY_PROMPT
-#
-# You can view or modify the current prompt data with various configuration methods:
-#
-# - <tt>conf.prompt_mode</tt>, <tt>conf.prompt_mode=</tt>.
-# - <tt>conf.prompt_c</tt>, <tt>conf.c=</tt>.
-# - <tt>conf.prompt_i</tt>, <tt>conf.i=</tt>.
-# - <tt>conf.prompt_s</tt>, <tt>conf.s=</tt>.
-# - <tt>conf.return_format</tt>, <tt>return_format=</tt>.
-#
-# ==== Prompt Specifiers
-#
-# A prompt's definition can include specifiers for which certain values are substituted:
-#
-# - <tt>%N</tt>: the name of the running program.
-# - <tt>%m</tt>: the value of <tt>self.to_s</tt>.
-# - <tt>%M</tt>: the value of <tt>self.inspect</tt>.
-# - <tt>%l</tt>: an indication of the type of string;
-#   one of <tt>"</tt>, <tt>'</tt>, <tt>/</tt>, <tt>]</tt>.
-# - <tt><i>NN</i>i</tt>: Indentation level.
-# - <tt><i>NN</i>n</tt>: Line number.
-# - <tt>%%</tt>: Literal <tt>%</tt>.
-#
-# === Verbosity
-#
-# By default, \IRB verbosity is disabled, which means that output is smaller
-# rather than larger.
-#
-# You can enable verbosity by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:VERBOSE] = true</tt>
-#   (the default is +nil+).
-# - Giving command-line options <tt>--verbose</tt>
-#   (the default is <tt>--noverbose</tt>).
-#
-# During a session, you can retrieve or set verbosity with methods
-# <tt>conf.verbose</tt> and <tt>conf.verbose=</tt>.
-#
-# === Help
-#
-# Command-line option <tt>--version</tt> causes \IRB to print its help text
-# and exit.
-#
-# === Version
-#
-# Command-line option <tt>--version</tt> causes \IRB to print its version text
-# and exit.
-#
-# == Input and Output
-#
-# === \Color Highlighting
-#
-# By default, \IRB color highlighting is enabled, and is used for both:
-#
-# - Input: As you type, \IRB reads the typed characters and highlights
-#   elements that it recognizes;
-#   it also highlights errors such as mismatched parentheses.
-# - Output: \IRB highlights syntactical elements.
-#
-# You can disable color highlighting by:
-#
-# - Adding to the configuration file: <tt>IRB.conf[:USE_COLORIZE] = false</tt>
-#   (the default value is +true+).
-# - Giving command-line option <tt>--nocolorize</tt>
-#
-# == Debugging
-#
-# Command-line option <tt>-d</tt> sets variables <tt>$VERBOSE</tt>
-# and <tt>$DEBUG</tt> to +true+;
-# these have no effect on \IRB output.
-#
-# === Warnings
-#
-# Command-line option <tt>-w</tt> suppresses warnings.
-#
-# Command-line option <tt>-W[_level_]<tt>
-# sets warning level; 0=silence, 1=medium, 2=verbose.

-# == Other Features
-#
-# === Load Modules
-#
-# You can specify the names of modules that are to be required at startup.
-#
-# \Array <tt>conf.load_modules</tt> determines the modules (if any)
-# that are to be required during session startup.
-# The array is used only during session startup,
-# so the initial value is the only one that counts.
-#
-# The default initial value is <tt>[]</tt> (load no modules):
-#
-#   irb(main):001> conf.load_modules
-#   => []
-#
-# You can set the default initial value via:
-#
-# - Command-line option <tt>-r</tt>
-#
-#     $ irb -r csv -r json
-#    irb(main):001> conf.load_modules
-#    => ["csv", "json"]
-#
-# - \Hash entry <tt>IRB.conf[:LOAD_MODULES] = _array_</tt>:
-#
-#     IRB.conf[:LOAD_MODULES] = %w[csv, json]
-#
-# Note that the configuration file entry overrides the command-line options.
-#
-# === RI Documentation Directories
-#
-# You can specify the paths to RI documentation directories
-# that are to be loaded (in addition to the default directories) at startup;
-# see details about RI by typing <tt>ri --help</tt>.
-#
-# \Array <tt>conf.extra_doc_dirs</tt> determines the directories (if any)
-# that are to be loaded during session startup.
-# The array is used only during session startup,
-# so the initial value is the only one that counts.
-#
-# The default initial value is <tt>[]</tt> (load no extra documentation):
-#
-#   irb(main):001> conf.extra_doc_dirs
-#   => []
-#
-# You can set the default initial value via:
-#
-# - Command-line option <tt>--extra_doc_dir</tt>
-#
-#     $ irb --extra-doc-dir your_doc_dir --extra-doc-dir my_doc_dir
-#     irb(main):001> conf.extra_doc_dirs
-#     => ["your_doc_dir", "my_doc_dir"]
-#
-# - \Hash entry <tt>IRB.conf[:EXTRA_DOC_DIRS] = _array_</tt>:
-#
-#     IRB.conf[:EXTRA_DOC_DIRS] = %w[your_doc_dir my_doc_dir]

-# === \IRB Name
-#
-# You can specify a name for \IRB.
+# IRB stands for "interactive Ruby" and is a tool to interactively execute Ruby
+# expressions read from the standard input.
+#
+# The +irb+ command from your shell will start the interpreter.
+#
+# == Usage
+#
+# Use of irb is easy if you know Ruby.
+#
+# When executing irb, prompts are displayed as follows. Then, enter the Ruby
+# expression. An input is executed when it is syntactically complete.
+#
+#     $ 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
+#
+# The singleline editor module or multiline editor module can be used with irb.
+# Use of multiline editor is default if it's installed.
+#
+# == Command line options

+#     --                Separate options of irb from the list of command-line args
+#
+# == Configuration
+#
+# IRB reads from <code>~/.irbrc</code> when it's invoked.
+#
+# If <code>~/.irbrc</code> doesn't exist, +irb+ will try to read in the following order:
+#
+# * +.irbrc+
+# * +irb.rc+
+# * +_irbrc+
+# * <code>$irbrc</code>
+#
+# The following are alternatives to the command line options. To use them type
+# as follows in an +irb+ session:
+#
+#     IRB.conf[:IRB_NAME]="irb"
+#     IRB.conf[:INSPECT_MODE]=nil
+#     IRB.conf[:IRB_RC] = nil
+#     IRB.conf[:BACK_TRACE_LIMIT]=16
+#     IRB.conf[:USE_LOADER] = false
+#     IRB.conf[:USE_MULTILINE] = nil
+#     IRB.conf[:USE_SINGLELINE] = nil
+#     IRB.conf[:USE_COLORIZE] = true
+#     IRB.conf[:USE_TRACER] = false
+#     IRB.conf[:USE_AUTOCOMPLETE] = true
+#     IRB.conf[:IGNORE_SIGINT] = true
+#     IRB.conf[:IGNORE_EOF] = false
+#     IRB.conf[:PROMPT_MODE] = :DEFAULT
+#     IRB.conf[:PROMPT] = {...}
+#
+# === Auto indentation
+#
+# To disable auto-indent mode in irb, add the following to your +.irbrc+:
+#
+#     IRB.conf[:AUTO_INDENT] = false
+#
+# === Autocompletion
+#
+# To enable autocompletion for irb, add the following to your +.irbrc+:
+#
+#     require 'irb/completion'
+#
+# === History
+#
+# By default, irb will store the last 1000 commands you used in
+# <code>IRB.conf[:HISTORY_FILE]</code> (<code>~/.irb_history</code> by default).
+#
+# If you want to disable history, add the following to your +.irbrc+:
+#
+#     IRB.conf[:SAVE_HISTORY] = nil
+#
+# See IRB::Context#save_history= for more information.
+#
+# The history of _results_ of commands evaluated is not stored by default,
+# but can be turned on to be stored with this +.irbrc+ setting:
+#
+#     IRB.conf[:EVAL_HISTORY] = <number>
+#
+# See IRB::Context#eval_history= and History class. The history of command
+# results is not permanently saved in any file.
+#
+# == Customizing the IRB Prompt
+#
+# In order to customize the prompt, you can change the following Hash:
+#
+#     IRB.conf[:PROMPT]
+#
+# This example can be used in your +.irbrc+
+#
+#     IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
+#       :AUTO_INDENT => false,          # disables auto-indent mode
+#       :PROMPT_I =>  ">> ",		# simple prompt
+#       :PROMPT_S => nil,		# prompt for continuated strings
+#       :PROMPT_C => nil,		# prompt for continuated statement
+#       :RETURN => "    ==>%s\n"	# format to return value
+#     }
+#
+#     IRB.conf[:PROMPT_MODE] = :MY_PROMPT
+#
+# Or, invoke irb with the above prompt mode by:
+#
+#     irb --prompt my-prompt
+#
+# Constants +PROMPT_I+, +PROMPT_S+ and +PROMPT_C+ specify 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 digits and means as same as printf("%NNd").
+#           # It can be omitted
+#     %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_N => "%N(%m):%03n:%i> ",
+#       :PROMPT_S => "%N(%m):%03n:%i%l ",
+#       :PROMPT_C => "%N(%m):%03n:%i* ",
+#       :RETURN => "%s\n" # used to printf
+#     }
+#
+# irb comes with a number of available modes:
+#
+#   # :NULL:
+#   #   :PROMPT_I:
+#   #   :PROMPT_N:
+#   #   :PROMPT_S:

-# \Class \Logger provides a simple but sophisticated logging utility that
-# you can use to create one or more
-# {event logs}[https://en.wikipedia.org/wiki/Logging_(software)#Event_logs]
-# for your program.
-# Each such log contains a chronological sequence of entries
-# that provides a record of the program's activities.
+# == Description
 #
-# == About the Examples
+# The Logger class provides a simple but sophisticated logging utility that
+# you can use to output messages.
 #
-# All examples on this page assume that \Logger has been required:
+# The messages have associated levels, such as +INFO+ or +ERROR+ that indicate
+# their importance.  You can then give the Logger a level, and only messages
+# at that level or higher will be printed.
 #
-#   require 'logger'
-#
-# == Synopsis
-#
-# Create a log with Logger.new:
-#
-#   # Single log file.
-#   logger = Logger.new('t.log')
-#   # Size-based rotated logging: 3 10-megabyte files.
-#   logger = Logger.new('t.log', 3, 10485760)
-#   # Period-based rotated logging: daily (also allowed: 'weekly', 'monthly').
-#   logger = Logger.new('t.log', 'daily')
-#   # Log to an IO stream.
-#   logger = Logger.new($stdout)
-#
-# Add entries (level, message) with Logger#add:
-#
-#   logger.add(Logger::DEBUG, 'Maximal debugging info')
-#   logger.add(Logger::INFO, 'Non-error information')
-#   logger.add(Logger::WARN, 'Non-error warning')
-#   logger.add(Logger::ERROR, 'Non-fatal error')
-#   logger.add(Logger::FATAL, 'Fatal error')
-#   logger.add(Logger::UNKNOWN, 'Most severe')
-#
-# Close the log with Logger#close:
-#
-#   logger.close
-#
-# == Entries
-#
-# You can add entries with method Logger#add:
-#
-#   logger.add(Logger::DEBUG, 'Maximal debugging info')
-#   logger.add(Logger::INFO, 'Non-error information')
-#   logger.add(Logger::WARN, 'Non-error warning')
-#   logger.add(Logger::ERROR, 'Non-fatal error')
-#   logger.add(Logger::FATAL, 'Fatal error')
-#   logger.add(Logger::UNKNOWN, 'Most severe')
-#
-# These shorthand methods also add entries:
-#
-#   logger.debug('Maximal debugging info')
-#   logger.info('Non-error information')
-#   logger.warn('Non-error warning')
-#   logger.error('Non-fatal error')
-#   logger.fatal('Fatal error')
-#   logger.unknown('Most severe')
-#
-# When you call any of these methods,
-# the entry may or may not be written to the log,
-# depending on the entry's severity and on the log level;
-# see {Log Level}[rdoc-ref:Logger@Log+Level]
-#
-# An entry always has:
-#
-# - A severity (the required argument to #add).
-# - An automatically created timestamp.
-#
-# And may also have:
-#
-# - A message.
-# - A program name.
-#
-# Example:
-#
-#   logger = Logger.new($stdout)
-#   logger.add(Logger::INFO, 'My message.', 'mung')
-#   # => I, [2022-05-07T17:21:46.536234 #20536]  INFO -- mung: My message.
-#
-# The default format for an entry is:
-#
-#   "%s, [%s #%d] %5s -- %s: %s\n"
-#
-# where the values to be formatted are:
-#
-# - \Severity (one letter).
-# - Timestamp.
-# - Process id.
-# - \Severity (word).
-# - Program name.
-# - Message.
-#
-# You can use a different entry format by:
-#
-# - Setting a custom format proc (affects following entries);
-#   see {formatter=}[Logger.html#attribute-i-formatter].
-# - Calling any of the methods above with a block
-#   (affects only the one entry).
-#   Doing so can have two benefits:
+# The levels are:
 #
-#   - Context: the block can evaluate the entire program context
-#     and create a context-dependent message.
-#   - Performance: the block is not evaluated unless the log level
-#     permits the entry actually to be written:
+# +UNKNOWN+:: An unknown message that should always be logged.
+# +FATAL+:: An unhandleable error that results in a program crash.
+# +ERROR+:: A handleable error condition.
+# +WARN+::  A warning.
+# +INFO+::  Generic (useful) information about system operation.
+# +DEBUG+:: Low-level information for developers.
 #
-#       logger.error { my_slow_message_generator }
+# For instance, in a production system, you may have your Logger set to
+# +INFO+ or even +WARN+.
+# When you are developing the system, however, you probably
+# want to know about the program's internal state, and would set the Logger to
+# +DEBUG+.
 #
-#     Contrast this with the string form, where the string is
-#     always evaluated, regardless of the log level:
+# *Note*: Logger does not escape or sanitize any messages passed to it.
+# Developers should be aware of when potentially malicious data (user-input)
+# is passed to Logger, and manually escape the untrusted data:
 #
-#       logger.error("#{my_slow_message_generator}")
+#   logger.info("User-input: #{input.dump}")
+#   logger.info("User-input: %p" % input)
 #
-# === \Severity
+# You can use #formatter= for escaping all data.
 #
-# The severity of a log entry has two effects:
+#   original_formatter = Logger::Formatter.new
+#   logger.formatter = proc { |severity, datetime, progname, msg|
+#     original_formatter.call(severity, datetime, progname, msg.dump)
+#   }
+#   logger.info(input)
 #
-# - Determines whether the entry is selected for inclusion in the log;
-#   see {Log Level}[rdoc-ref:Logger@Log+Level].
-# - Indicates to any log reader (whether a person or a program)
-#   the relative importance of the entry.
+# === Example
 #
-# === Timestamp
+# This creates a Logger that outputs to the standard output stream, with a
+# level of +WARN+:
 #
-# The timestamp for a log entry is generated automatically
-# when the entry is created.
-#
-# The logged timestamp is formatted by method
-# {Time#strftime}[rdoc-ref:Time#strftime]
-# using this format string:
-#
-#   '%Y-%m-%dT%H:%M:%S.%6N'
-#
-# Example:
-#
-#   logger = Logger.new($stdout)
-#   logger.add(Logger::INFO)
-#   # => I, [2022-05-07T17:04:32.318331 #20536]  INFO -- : nil
-#
-# You can set a different format using method #datetime_format=.
-#
-# === Message
+#   require 'logger'
 #
-# The message is an optional argument to an entry method:
+#   logger = Logger.new(STDOUT)
+#   logger.level = Logger::WARN
 #
-#   logger = Logger.new($stdout)
-#   logger.add(Logger::INFO, 'My message')
-#   # => I, [2022-05-07T18:15:37.647581 #20536]  INFO -- : My message
+#   logger.debug("Created logger")
+#   logger.info("Program started")
+#   logger.warn("Nothing to do!")
 #
-# For the default entry formatter, <tt>Logger::Formatter</tt>,
-# the message object may be:
+#   path = "a_non_existent_file"
 #
-# - A string: used as-is.
-# - An Exception: <tt>message.message</tt> is used.
-# - Anything else: <tt>message.inspect</tt> is used.
+#   begin
+#     File.foreach(path) do |line|
+#       unless line =~ /^(\w+) = (.*)$/
+#         logger.error("Line in wrong format: #{line.chomp}")
+#       end
+#     end
+#   rescue => err
+#     logger.fatal("Caught exception; exiting")
+#     logger.fatal(err)
+#   end
 #
-# *Note*: Logger::Formatter does not escape or sanitize
-# the message passed to it.
-# Developers should be aware that malicious data (user input)
-# may be in the message, and should explicitly escape untrusted data.
+# Because the Logger's level is set to +WARN+, only the warning, error, and
+# fatal messages are recorded.  The debug and info messages are silently
+# discarded.
 #
-# You can use a custom formatter to escape message data;
-# see the example at {formatter=}[Logger.html#attribute-i-formatter].
+# === Features
 #
-# === Program Name
+# There are several interesting features that Logger provides, like
+# auto-rolling of log files, setting the format of log messages, and
+# specifying a program name in conjunction with the message.  The next section
+# shows you how to achieve these things.
 #
-# The program name is an optional argument to an entry method:
 #
-#   logger = Logger.new($stdout)
-#   logger.add(Logger::INFO, 'My message', 'mung')
-#   # => I, [2022-05-07T18:17:38.084716 #20536]  INFO -- mung: My message
+# == HOWTOs
 #
-# The default program name for a new logger may be set in the call to
-# Logger.new via optional keyword argument +progname+:
+# === How to create a logger
 #
-#   logger = Logger.new('t.log', progname: 'mung')
+# The options below give you various choices, in more or less increasing
+# complexity.
 #
-# The default program name for an existing logger may be set
-# by a call to method #progname=:
+# 1. Create a logger which logs messages to STDERR/STDOUT.
 #
-#   logger.progname = 'mung'
+#      logger = Logger.new(STDERR)
+#      logger = Logger.new(STDOUT)
 #
-# The current program name may be retrieved with method
-# {progname}[Logger.html#attribute-i-progname]:
+# 2. Create a logger for the file which has the specified name.
 #
-#   logger.progname # => "mung"
+#      logger = Logger.new('logfile.log')
 #
-# == Log Level
+# 3. Create a logger for the specified file.
 #
-# The log level setting determines whether an entry is actually
-# written to the log, based on the entry's severity.
+#      file = File.open('foo.log', File::WRONLY | File::APPEND)
+#      # To create new logfile, add File::CREAT like:
+#      # file = File.open('foo.log', File::WRONLY | File::APPEND | File::CREAT)
+#      logger = Logger.new(file)
 #
-# These are the defined severities (least severe to most severe):
+# 4. Create a logger which ages the logfile once it reaches a certain size.
+#    Leave 10 "old" log files where each file is about 1,024,000 bytes.
 #
-#   logger = Logger.new($stdout)
-#   logger.add(Logger::DEBUG, 'Maximal debugging info')
-#   # => D, [2022-05-07T17:57:41.776220 #20536] DEBUG -- : Maximal debugging info

-#   # => F, [2022-05-07T18:05:24.703931 #20536] FATAL -- : Fatal error
-#   logger.add(Logger::UNKNOWN, 'Most severe')
-#   # => A, [2022-05-07T18:07:54.657491 #20536]   ANY -- : Most severe
+#      logger = Logger.new('foo.log', 10, 1024000)
 #
-# The default initial level setting is Logger::DEBUG, the lowest level,
-# which means that all entries are to be written, regardless of severity:
+# 5. Create a logger which ages the logfile daily/weekly/monthly.
 #
-#   logger = Logger.new($stdout)
-#   logger.level # => 0
-#   logger.add(0, "My message")
-#   # => D, [2022-05-11T15:10:59.773668 #20536] DEBUG -- : My message
+#      logger = Logger.new('foo.log', 'daily')
+#      logger = Logger.new('foo.log', 'weekly')
+#      logger = Logger.new('foo.log', 'monthly')
 #
-# You can specify a different setting in a new logger
-# using keyword argument +level+ with an appropriate value:
+# === How to log a message
 #
-#   logger = Logger.new($stdout, level: Logger::ERROR)
-#   logger = Logger.new($stdout, level: 'error')
-#   logger = Logger.new($stdout, level: :error)
-#   logger.level # => 3
+# Notice the different methods (+fatal+, +error+, +info+) being used to log
+# messages of various levels?  Other methods in this family are +warn+ and
+# +debug+.  +add+ is used below to log a message of an arbitrary (perhaps
+# dynamic) level.
 #
-# With this level, entries with severity Logger::ERROR and higher
-# are written, while those with lower severities are not written:
+# 1. Message in a block.
 #
-#   logger = Logger.new($stdout, level: Logger::ERROR)
-#   logger.add(3)
-#   # => E, [2022-05-11T15:17:20.933362 #20536] ERROR -- : nil
-#   logger.add(2) # Silent.
+#      logger.fatal { "Argument 'foo' not given." }
 #
-# You can set the log level for an existing logger
-# with method #level=:
+# 2. Message as a string.
 #
-#   logger.level = Logger::ERROR
+#      logger.error "Argument #{@foo} mismatch."
 #
-# These shorthand methods also set the level:
+# 3. With progname.
 #
-#   logger.debug! # => 0
-#   logger.info!  # => 1
-#   logger.warn!  # => 2
-#   logger.error! # => 3
-#   logger.fatal! # => 4
+#      logger.info('initialize') { "Initializing..." }
 #
-# You can retrieve the log level with method #level.
+# 4. With severity.
 #
-#   logger.level = Logger::ERROR
-#   logger.level # => 3
+#      logger.add(Logger::FATAL) { 'Fatal error!' }
 #
-# These methods return whether a given
-# level is to be written:
+# The block form allows you to create potentially complex log messages,
+# but to delay their evaluation until and unless the message is
+# logged.  For example, if we have the following:
 #
-#   logger.level = Logger::ERROR
-#   logger.debug? # => false
-#   logger.info?  # => false
-#   logger.warn?  # => false
-#   logger.error? # => true
-#   logger.fatal? # => true
+#     logger.debug { "This is a " + potentially + " expensive operation" }
 #
-# == Log File Rotation
+# If the logger's level is +INFO+ or higher, no debug messages will be logged,
+# and the entire block will not even be evaluated.  Compare to this:
 #
-# By default, a log file is a single file that grows indefinitely
-# (until explicitly closed); there is no file rotation.
+#     logger.debug("This is a " + potentially + " expensive operation")
 #
-# To keep log files to a manageable size,
-# you can use _log_ _file_ _rotation_, which uses multiple log files:
+# Here, the string concatenation is done every time, even if the log
+# level is not set to show the debug message.
 #
-# - Each log file has entries for a non-overlapping
-#   time interval.
-# - Only the most recent log file is open and active;
-#   the others are closed and inactive.
+# === How to close a logger
 #
-# === Size-Based Rotation
+#      logger.close
 #
-# For size-based log file rotation, call Logger.new with:
+# === Setting severity threshold
 #
-# - Argument +logdev+ as a file path.
-# - Argument +shift_age+ with a positive integer:
-#   the number of log files to be in the rotation.
-# - Argument +shift_size+ as a positive integer:
-#   the maximum size (in bytes) of each log file;
-#   defaults to 1048576 (1 megabyte).
+# 1. Original interface.
 #
-# Examples:
+#      logger.sev_threshold = Logger::WARN
 #
-#   logger = Logger.new('t.log', 3)           # Three 1-megabyte files.
-#   logger = Logger.new('t.log', 5, 10485760) # Five 10-megabyte files.
+# 2. Log4r (somewhat) compatible interface.
 #
-# For these examples, suppose:
+#      logger.level = Logger::INFO
 #
-#   logger = Logger.new('t.log', 3)
+#      # DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN
 #
-# Logging begins in the new log file, +t.log+;
-# the log file is "full" and ready for rotation
-# when a new entry would cause its size to exceed +shift_size+.
+# 3. Symbol or String (case insensitive)
 #
-# The first time +t.log+ is full:
+#      logger.level = :info
+#      logger.level = 'INFO'
 #
-# - +t.log+ is closed and renamed to +t.log.0+.
-# - A new file +t.log+ is opened.
+#      # :debug < :info < :warn < :error < :fatal < :unknown
 #
-# The second time +t.log+ is full:
+# 4. Constructor
 #
-# - +t.log.0 is renamed as +t.log.1+.
-# - +t.log+ is closed and renamed to +t.log.0+.
-# - A new file +t.log+ is opened.
+#      Logger.new(logdev, level: Logger::INFO)
+#      Logger.new(logdev, level: :info)
+#      Logger.new(logdev, level: 'INFO')
 #
-# Each subsequent time that +t.log+ is full,
-# the log files are rotated:
+# == Format
 #
-# - +t.log.1+ is removed.
-# - +t.log.0 is renamed as +t.log.1+.
-# - +t.log+ is closed and renamed to +t.log.0+.
-# - A new file +t.log+ is opened.
+# Log messages are rendered in the output stream in a certain format by
+# default.  The default format and a sample are shown below:
 #
-# === Periodic Rotation
+# Log format:
+#   SeverityID, [DateTime #pid] SeverityLabel -- ProgName: message
 #
-# For periodic rotation, call Logger.new with:
+# Log sample:

-  #   Each of the following methods automatically starts and finishes
-  #   a {session}[rdoc-ref:Net::HTTP@Sessions] that sends a single request:
-  #
-  #     # Return string response body.
-  #     Net::HTTP.get(hostname, path)
-  #     Net::HTTP.get(uri)
-  #
-  #     # Write string response body to $stdout.
-  #     Net::HTTP.get_print(hostname, path)
-  #     Net::HTTP.get_print(uri)
-  #
-  #     # Return response as Net::HTTPResponse object.
-  #     Net::HTTP.get_response(hostname, path)
-  #     Net::HTTP.get_response(uri)

+  # == An HTTP client API for Ruby.
   #
-  # The methods cited above are convenience methods that, via their few arguments,
-  # allow minimal control over the requests.
-  # For greater control, consider using {request objects}[rdoc-ref:Net::HTTPRequest].
+  # Net::HTTP provides a rich library which can be used to build HTTP
+  # user-agents.  For more details about HTTP see
+  # [RFC2616](http://www.ietf.org/rfc/rfc2616.txt).
   #
-  # == URIs
+  # Net::HTTP is designed to work closely with URI.  URI::HTTP#host,
+  # URI::HTTP#port and URI::HTTP#request_uri are designed to work with
+  # Net::HTTP.
   #
-  # On the internet, a URI
-  # ({Universal Resource Identifier}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier])
-  # is a string that identifies a particular resource.
-  # It consists of some or all of: scheme, hostname, path, query, and fragment;
-  # see {URI syntax}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax].
+  # If you are only performing a few GET requests you should try OpenURI.
   #
-  # A Ruby {URI::Generic}[rdoc-ref:URI::Generic] object
-  # represents an internet URI.
-  # It provides, among others, methods
-  # +scheme+, +hostname+, +path+, +query+, and +fragment+.
+  # == Simple Examples
   #
-  # === Schemes
+  # All examples assume you have loaded Net::HTTP with:
   #
-  # An internet \URI has
-  # a {scheme}[https://en.wikipedia.org/wiki/List_of_URI_schemes].
+  #   require 'net/http'
   #
-  # The two schemes supported in \Net::HTTP are <tt>'https'</tt> and <tt>'http'</tt>:
+  # This will also require 'uri' so you don't need to require it separately.
   #
-  #   uri.scheme                       # => "https"
-  #   URI('http://example.com').scheme # => "http"
+  # The Net::HTTP methods in the following section do not persist
+  # connections.  They are not recommended if you are performing many HTTP
+  # requests.
   #
-  # === Hostnames
+  # === GET
   #
-  # A hostname identifies a server (host) to which requests may be sent:
+  #   Net::HTTP.get('example.com', '/index.html') # => String
   #
-  #   hostname = uri.hostname # => "jsonplaceholder.typicode.com"
-  #   Net::HTTP.start(hostname) do |http|
-  #     # Some HTTP stuff.
-  #   end
+  # === GET by URI
   #
-  # === Paths
+  #   uri = URI('http://example.com/index.html?count=10')
+  #   Net::HTTP.get(uri) # => String
   #
-  # A host-specific path identifies a resource on the host:
+  # === GET with Dynamic Parameters
   #
-  #   _uri = uri.dup
-  #   _uri.path = '/todos/1'
-  #   hostname = _uri.hostname
-  #   path = _uri.path
-  #   Net::HTTP.get(hostname, path)
+  #   uri = URI('http://example.com/index.html')
+  #   params = { :limit => 10, :page => 3 }
+  #   uri.query = URI.encode_www_form(params)
   #
-  # === Queries
+  #   res = Net::HTTP.get_response(uri)
+  #   puts res.body if res.is_a?(Net::HTTPSuccess)
   #
-  # A host-specific query adds name/value pairs to the URI:
+  # === POST
   #
-  #   _uri = uri.dup
-  #   params = {userId: 1, completed: false}
-  #   _uri.query = URI.encode_www_form(params)
-  #   _uri # => #<URI::HTTPS https://jsonplaceholder.typicode.com?userId=1&completed=false>
-  #   Net::HTTP.get(_uri)
+  #   uri = URI('http://www.example.com/search.cgi')
+  #   res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
+  #   puts res.body
   #
-  # === Fragments
+  # === POST with Multiple Values
   #
-  # A {URI fragment}[https://en.wikipedia.org/wiki/URI_fragment] has no effect
-  # in \Net::HTTP;
-  # the same data is returned, regardless of whether a fragment is included.
+  #   uri = URI('http://www.example.com/search.cgi')
+  #   res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
+  #   puts res.body
   #
-  # == Request Headers
+  # == How to use Net::HTTP
   #
-  # Request headers may be used to pass additional information to the host,
-  # similar to arguments passed in a method call;
-  # each header is a name/value pair.
+  # The following example code can be used as the basis of an HTTP user-agent
+  # which can perform a variety of request types using persistent
+  # connections.
   #
-  # Each of the \Net::HTTP methods that sends a request to the host
-  # has optional argument +headers+,
-  # where the headers are expressed as a hash of field-name/value pairs:
+  #   uri = URI('http://example.com/some_path?query=string')
   #
-  #   headers = {Accept: 'application/json', Connection: 'Keep-Alive'}
-  #   Net::HTTP.get(uri, headers)
+  #   Net::HTTP.start(uri.host, uri.port) do |http|
+  #     request = Net::HTTP::Get.new uri
   #
-  # See lists of both standard request fields and common request fields at
-  # {Request Fields}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Request_fields].
-  # A host may also accept other custom fields.
+  #     response = http.request request # Net::HTTPResponse object
+  #   end
   #
-  # == \HTTP Sessions
+  # Net::HTTP::start immediately creates a connection to an HTTP server which
+  # is kept open for the duration of the block.  The connection will remain
+  # open for multiple requests in the block if the server indicates it
+  # supports persistent connections.
   #
-  # A _session_ is a connection between a server (host) and a client that:
+  # If you wish to re-use a connection across multiple HTTP requests without
+  # automatically closing it you can use ::new and then call #start and
+  # #finish manually.
   #
-  # - Is begun by instance method Net::HTTP#start.
-  # - May contain any number of requests.
-  # - Is ended by instance method Net::HTTP#finish.
+  # The request types Net::HTTP supports are listed below in the section "HTTP
+  # Request Classes".
   #
-  # See example sessions at {Strategies}[rdoc-ref:Net::HTTP@Strategies].
+  # For all the Net::HTTP request objects and shortcut request methods you may
+  # supply either a String for the request path or a URI from which Net::HTTP
+  # will extract the request path.
   #
-  # === Session Using \Net::HTTP.start
+  # === Response Data
   #
-  # If you have many requests to make to a single host (and port),
-  # consider using singleton method Net::HTTP.start with a block;
-  # the method handles the session automatically by:
+  #   uri = URI('http://example.com/index.html')
+  #   res = Net::HTTP.get_response(uri)
   #
-  # - Calling #start before block execution.
-  # - Executing the block.
-  # - Calling #finish after block execution.
+  #   # Headers
+  #   res['Set-Cookie']            # => String
+  #   res.get_fields('set-cookie') # => Array
+  #   res.to_hash['set-cookie']    # => Array
+  #   puts "Headers: #{res.to_hash.inspect}"
   #
-  # In the block, you can use these instance methods,
-  # each of which that sends a single request:
+  #   # Status
+  #   puts res.code       # => '200'
+  #   puts res.message    # => 'OK'
+  #   puts res.class.name # => 'HTTPOK'
   #
-  # - {HTTP methods}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods]:
+  #   # Body
+  #   puts res.body
   #
-  #   - #get, #request_get: GET.
-  #   - #head, #request_head: HEAD.
-  #   - #post, #request_post: POST.
-  #   - #delete: DELETE.
-  #   - #options: OPTIONS.
-  #   - #trace: TRACE.
-  #   - #patch: PATCH.
+  # === Following Redirection
   #
-  # - {WebDAV methods}[https://en.wikipedia.org/wiki/WebDAV#Implementation]:
+  # Each Net::HTTPResponse object belongs to a class for its response code.
   #
-  #   - #copy: COPY.
-  #   - #lock: LOCK.
-  #   - #mkcol: MKCOL.
-  #   - #move: MOVE.
-  #   - #propfind: PROPFIND.
-  #   - #proppatch: PROPPATCH.
-  #   - #unlock: UNLOCK.
+  # For example, all 2XX responses are instances of a Net::HTTPSuccess
+  # subclass, a 3XX response is an instance of a Net::HTTPRedirection
+  # subclass and a 200 response is an instance of the Net::HTTPOK class.  For
+  # details of response classes, see the section "HTTP Response Classes"
+  # below.
   #
-  # === Session Using \Net::HTTP.start and \Net::HTTP.finish
+  # Using a case statement you can handle various types of responses properly:
   #
-  # You can manage a session manually using methods #start and #finish:
+  #   def fetch(uri_str, limit = 10)
+  #     # You should choose a better exception.
+  #     raise ArgumentError, 'too many HTTP redirects' if limit == 0
   #
-  #   http = Net::HTTP.new(hostname)
-  #   http.start
-  #   http.get('/todos/1')
-  #   http.get('/todos/2')
-  #   http.delete('/posts/1')
-  #   http.finish # Needed to free resources.
+  #     response = Net::HTTP.get_response(URI(uri_str))
   #
-  # === Single-Request Session
+  #     case response
+  #     when Net::HTTPSuccess then
+  #       response
+  #     when Net::HTTPRedirection then
+  #       location = response['location']
+  #       warn "redirected to #{location}"
+  #       fetch(location, limit - 1)
+  #     else
+  #       response.value
+  #     end
+  #   end
   #
-  # Certain convenience methods automatically handle a session by:
+  #   print fetch('http://www.ruby-lang.org')
   #
-  # - Creating an \HTTP object
-  # - Starting a session.
-  # - Sending a single request.
-  # - Finishing the session.
-  # - Destroying the object.
+  # === POST
   #
-  # Such methods that send GET requests:
+  # A POST can be made using the Net::HTTP::Post request class.  This example
+  # creates a URL encoded POST body:
   #
-  # - ::get: Returns the string response body.
-  # - ::get_print: Writes the string response body to $stdout.
-  # - ::get_response: Returns a Net::HTTPResponse object.
+  #   uri = URI('http://www.example.com/todo.cgi')
+  #   req = Net::HTTP::Post.new(uri)
+  #   req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')
   #
-  # Such methods that send POST requests:
+  #   res = Net::HTTP.start(uri.hostname, uri.port) do |http|
+  #     http.request(req)
+  #   end
   #
-  # - ::post: Posts data to the host.
-  # - ::post_form: Posts form data to the host.
+  #   case res
+  #   when Net::HTTPSuccess, Net::HTTPRedirection
+  #     # OK
+  #   else
+  #     res.value
+  #   end
   #
-  # == \HTTP Requests and Responses
+  # To send multipart/form-data use Net::HTTPHeader#set_form:
   #
-  # Many of the methods above are convenience methods,
-  # each of which sends a request and returns a string
-  # without directly using \Net::HTTPRequest and \Net::HTTPResponse objects.
+  #   req = Net::HTTP::Post.new(uri)
+  #   req.set_form([['upload', File.open('foo.bar')]], 'multipart/form-data')
   #
-  # You can, however, directly create a request object, send the request,
-  # and retrieve the response object; see:
+  # Other requests that can contain a body such as PUT can be created in the
+  # same way using the corresponding request class (Net::HTTP::Put).
   #
-  # - Net::HTTPRequest.
-  # - Net::HTTPResponse.
+  # === Setting Headers
   #
-  # == Following Redirection
+  # The following example performs a conditional GET using the
+  # If-Modified-Since header.  If the files has not been modified since the
+  # time in the header a Not Modified response will be returned.  See RFC 2616
+  # section 9.3 for further details.
   #
-  # Each returned response is an instance of a subclass of Net::HTTPResponse.
-  # See the {response class hierarchy}[rdoc-ref:Net::HTTPResponse@Response+Subclasses].
+  #   uri = URI('http://example.com/cached_response')
+  #   file = File.stat 'cached_response'
   #
-  # In particular, class Net::HTTPRedirection is the parent
-  # of all redirection classes.
-  # This allows you to craft a case statement to handle redirections properly:
+  #   req = Net::HTTP::Get.new(uri)
+  #   req['If-Modified-Since'] = file.mtime.rfc2822
   #
-  #   def fetch(uri, limit = 10)
-  #     # You should choose a better exception.
-  #     raise ArgumentError, 'Too many HTTP redirects' if limit == 0
-  #
-  #     res = Net::HTTP.get_response(URI(uri))
-  #     case res
-  #     when Net::HTTPSuccess     # Any success class.
-  #       res
-  #     when Net::HTTPRedirection # Any redirection class.
-  #       location = res['Location']
-  #       warn "Redirected to #{location}"
-  #       fetch(location, limit - 1)
-  #     else                      # Any other class.
-  #       res.value
-  #     end
-  #   end
+  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
+  #     http.request(req)
+  #   }
   #
-  #   fetch(uri)
+  #   open 'cached_response', 'w' do |io|
+  #     io.write res.body
+  #   end if res.is_a?(Net::HTTPSuccess)
   #
-  # == Basic Authentication
+  # === Basic Authentication
   #
   # Basic authentication is performed according to
-  # {RFC2617}[http://www.ietf.org/rfc/rfc2617.txt]:
+  # [RFC2617](http://www.ietf.org/rfc/rfc2617.txt).
+  #
+  #   uri = URI('http://example.com/index.html?key=value')
   #
   #   req = Net::HTTP::Get.new(uri)
-  #   req.basic_auth('user', 'pass')
-  #   res = Net::HTTP.start(hostname) do |http|
+  #   req.basic_auth 'user', 'pass'
+  #
+  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
   #     http.request(req)
-  #   end
+  #   }
+  #   puts res.body

-  # == Streaming Response Bodies
+  # === Streaming Response Bodies
   #
-  # By default \Net::HTTP reads an entire response into memory.  If you are
+  # By default Net::HTTP reads an entire response into memory.  If you are
   # handling large files or wish to implement a progress bar you can instead
   # stream the body directly to an IO.
   #
-  #   Net::HTTP.start(hostname) do |http|
-  #     req = Net::HTTP::Get.new(uri)
-  #     http.request(req) do |res|
-  #       open('t.tmp', 'w') do |f|
-  #         res.read_body do |chunk|
-  #           f.write chunk
+  #   uri = URI('http://example.com/large_file')
+  #
+  #   Net::HTTP.start(uri.host, uri.port) do |http|
+  #     request = Net::HTTP::Get.new uri
+  #
+  #     http.request request do |response|
+  #       open 'large_file', 'w' do |io|
+  #         response.read_body do |chunk|
+  #           io.write chunk
   #         end
   #       end
   #     end
   #   end
   #
-  # == HTTPS
-  #
-  # HTTPS is enabled for an \HTTP connection by Net::HTTP#use_ssl=:
-  #
-  #   Net::HTTP.start(hostname, :use_ssl => true) do |http|
-  #     req = Net::HTTP::Get.new(uri)
-  #     res = http.request(req)
-  #   end
-  #
-  # Or if you simply want to make a GET request, you may pass in a URI
-  # object that has an \HTTPS URL. \Net::HTTP automatically turns on TLS
-  # verification if the URI object has a 'https' URI scheme:
-  #
-  #   uri # => #<URI::HTTPS https://jsonplaceholder.typicode.com/>
-  #   Net::HTTP.get(uri)
-  #
-  # == Proxy Server
-  #
-  # An \HTTP object can have
-  # a {proxy server}[https://en.wikipedia.org/wiki/Proxy_server].
+  # === HTTPS
   #
-  # You can create an \HTTP object with a proxy server
-  # using method Net::HTTP.new or method Net::HTTP.start.
+  # HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=.
   #
-  # The proxy may be defined either by argument +p_addr+
-  # or by environment variable <tt>'http_proxy'</tt>.
+  #   uri = URI('https://secure.example.com/some_path?query=string')
   #
-  # === Proxy Using Argument +p_addr+ as a \String
-  #
-  # When argument +p_addr+ is a string hostname,
-  # the returned +http+ has the given host as its proxy:
-  #
-  #   http = Net::HTTP.new(hostname, nil, 'proxy.example')
-  #   http.proxy?          # => true
-  #   http.proxy_from_env? # => false
-  #   http.proxy_address   # => "proxy.example"
-  #   # These use default values.
-  #   http.proxy_port      # => 80
-  #   http.proxy_user      # => nil
-  #   http.proxy_pass      # => nil
-  #
-  # The port, username, and password for the proxy may also be given:
-  #
-  #   http = Net::HTTP.new(hostname, nil, 'proxy.example', 8000, 'pname', 'ppass')
-  #   # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
-  #   http.proxy?          # => true
-  #   http.proxy_from_env? # => false
-  #   http.proxy_address   # => "proxy.example"
-  #   http.proxy_port      # => 8000
-  #   http.proxy_user      # => "pname"
-  #   http.proxy_pass      # => "ppass"
-  #
-  # === Proxy Using '<tt>ENV['http_proxy']</tt>'
-  #
-  # When environment variable <tt>'http_proxy'</tt>
-  # is set to a \URI string,
-  # the returned +http+ will have the server at that URI as its proxy;
-  # note that the \URI string must have a protocol
-  # such as <tt>'http'</tt> or <tt>'https'</tt>:
-  #
-  #   ENV['http_proxy'] = 'http://example.com'
-  #   http = Net::HTTP.new(hostname)
-  #   http.proxy?          # => true
-  #   http.proxy_from_env? # => true
-  #   http.proxy_address   # => "example.com"
-  #   # These use default values.
-  #   http.proxy_port      # => 80
-  #   http.proxy_user      # => nil
-  #   http.proxy_pass      # => nil
-  #
-  # The \URI string may include proxy username, password, and port number:
-  #
-  #   ENV['http_proxy'] = 'http://pname:ppass@example.com:8000'
-  #   http = Net::HTTP.new(hostname)
-  #   http.proxy?          # => true
-  #   http.proxy_from_env? # => true
-  #   http.proxy_address   # => "example.com"
-  #   http.proxy_port      # => 8000
-  #   http.proxy_user      # => "pname"
-  #   http.proxy_pass      # => "ppass"
+  #   Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
+  #     request = Net::HTTP::Get.new uri
+  #     response = http.request request # Net::HTTPResponse object
+  #   end
   #
-  # === Filtering Proxies
+  # Or if you simply want to make a GET request, you may pass in an URI
+  # object that has an HTTPS URL. Net::HTTP automatically turns on TLS
+  # verification if the URI object has a 'https' URI scheme.
   #
-  # With method Net::HTTP.new (but not Net::HTTP.start),
-  # you can use argument +p_no_proxy+ to filter proxies:
+  #   uri = URI('https://example.com/')
+  #   Net::HTTP.get(uri) # => String
   #
-  # - Reject a certain address:
-  #
-  #     http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example')
-  #     http.proxy_address # => nil
-  #
-  # - Reject certain domains or subdomains:
-  #
-  #     http = Net::HTTP.new('example.com', nil, 'my.proxy.example', 8000, 'pname', 'ppass', 'proxy.example')
-  #     http.proxy_address # => nil
-  #

-  #
-  # == Compression and Decompression
-  #
-  # \Net::HTTP does not compress the body of a request before sending.
-  #
-  # By default, \Net::HTTP adds header <tt>'Accept-Encoding'</tt>
-  # to a new {request object}[rdoc-ref:Net::HTTPRequest]:
-  #
-  #   Net::HTTP::Get.new(uri)['Accept-Encoding']
-  #   # => "gzip;q=1.0,deflate;q=0.6,identity;q=0.3"
-  #
-  # This requests the server to zip-encode the response body if there is one;
-  # the server is not required to do so.
-  #
-  # \Net::HTTP does not automatically decompress a response body
-  # if the response has header <tt>'Content-Range'</tt>.
-  #
-  # Otherwise decompression (or not) depends on the value of header
-  # {Content-Encoding}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#content-encoding-response-header]:
-  #
-  # - <tt>'deflate'</tt>, <tt>'gzip'</tt>, or <tt>'x-gzip'</tt>:
-  #   decompresses the body and deletes the header.
-  # - <tt>'none'</tt> or <tt>'identity'</tt>:
-  #   does not decompress the body, but deletes the header.
-  # - Any other value:
-  #   leaves the body and header unchanged.

+# The HTTPHeader module defines methods for reading and writing
+# HTTP headers.
 #
-# The \HTTPHeader module provides access to \HTTP headers.
-#
-# The module is included in:
-#
-# - Net::HTTPGenericRequest (and therefore Net::HTTPRequest).
-# - Net::HTTPResponse.
-#
-# The headers are a hash-like collection of key/value pairs called _fields_.
-#
-# == Request and Response Fields
-#
-# Headers may be included in:
-#
-# - A Net::HTTPRequest object:
-#   the object's headers will be sent with the request.
-#   Any fields may be defined in the request;
-#   see {Setters}[rdoc-ref:Net::HTTPHeader@Setters].
-# - A Net::HTTPResponse object:
-#   the objects headers are usually those returned from the host.
-#   Fields may be retrieved from the object;
-#   see {Getters}[rdoc-ref:Net::HTTPHeader@Getters]
-#   and {Iterators}[rdoc-ref:Net::HTTPHeader@Iterators].
-#
-# Exactly which fields should be sent or expected depends on the host;
-# see:
-#
-# - {Request fields}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Request_fields].
-# - {Response fields}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Response_fields].
-#
-# == About the Examples
-#
-# :include: doc/net-http/examples.rdoc
-#
-# == Fields
-#
-# A header field is a key/value pair.
-#
-# === Field Keys
-#
-# A field key may be:
-#
-# - A string: Key <tt>'Accept'</tt> is treated as if it were
-#   <tt>'Accept'.downcase</tt>;  i.e., <tt>'accept'</tt>.
-# - A symbol: Key <tt>:Accept</tt> is treated as if it were
-#   <tt>:Accept.to_s.downcase</tt>;  i.e., <tt>'accept'</tt>.
-#
-# Examples:
-#
-#   req = Net::HTTP::Get.new(uri)
-#   req[:accept]  # => "*/*"
-#   req['Accept'] # => "*/*"
-#   req['ACCEPT'] # => "*/*"
-#
-#   req['accept'] = 'text/html'
-#   req[:accept] = 'text/html'
-#   req['ACCEPT'] = 'text/html'
-#
-# === Field Values
-#
-# A field value may be returned as an array of strings or as a string:
-#
-# - These methods return field values as arrays:
-#
-#   - #get_fields: Returns the array value for the given key,
-#     or +nil+ if it does not exist.
-#   - #to_hash: Returns a hash of all header fields:
-#     each key is a field name; its value is the array value for the field.
-#
-# - These methods return field values as string;
-#   the string value for a field is equivalent to
-#   <tt>self[key.downcase.to_s].join(', '))</tt>:
-#
-#   - #[]: Returns the string value for the given key,
-#     or +nil+ if it does not exist.
-#   - #fetch: Like #[], but accepts a default value
-#     to be returned if the key does not exist.
-#
-# The field value may be set:
-#
-# - #[]=: Sets the value for the given key;
-#   the given value may be a string, a symbol, an array, or a hash.
-# - #add_field: Adds a given value to a value for the given key
-#   (not overwriting the existing value).
-# - #delete: Deletes the field for the given key.
-#
-# Example field values:
-#
-# - \String:
-#
-#     req['Accept'] = 'text/html' # => "text/html"
-#     req['Accept']               # => "text/html"
-#     req.get_fields('Accept')    # => ["text/html"]
-#
-# - \Symbol:
-#
-#     req['Accept'] = :text    # => :text
-#     req['Accept']            # => "text"
-#     req.get_fields('Accept') # => ["text"]
-#
-# - Simple array:
-#
-#     req[:foo] = %w[bar baz bat]
-#     req[:foo]            # => "bar, baz, bat"
-#     req.get_fields(:foo) # => ["bar", "baz", "bat"]
-#
-# - Simple hash:
-#
-#     req[:foo] = {bar: 0, baz: 1, bat: 2}
-#     req[:foo]            # => "bar, 0, baz, 1, bat, 2"
-#     req.get_fields(:foo) # => ["bar", "0", "baz", "1", "bat", "2"]
-#
-# - Nested:
-#
-#     req[:foo] = [%w[bar baz], {bat: 0, bam: 1}]
-#     req[:foo]            # => "bar, baz, bat, 0, bam, 1"
-#     req.get_fields(:foo) # => ["bar", "baz", "bat", "0", "bam", "1"]
-#
-#     req[:foo] = {bar: %w[baz bat], bam: {bah: 0, bad: 1}}
-#     req[:foo]            # => "bar, baz, bat, bam, bah, 0, bad, 1"
-#     req.get_fields(:foo) # => ["bar", "baz", "bat", "bam", "bah", "0", "bad", "1"]
-#
-# == Convenience Methods
-#
-# Various convenience methods retrieve values, set values, query values,
-# set form values, or iterate over fields.
-#
-# === Setters
-#
-# \Method #[]= can set any field, but does little to validate the new value;
-# some of the other setter methods provide some validation:
-#
-# - #[]=: Sets the string or array value for the given key.
-# - #add_field: Creates or adds to the array value for the given key.
-# - #basic_auth: Sets the string authorization header for <tt>'Authorization'</tt>.
-# - #content_length=: Sets the integer length for field <tt>'Content-Length</tt>.
-# - #content_type=: Sets the string value for field <tt>'Content-Type'</tt>.
-# - #proxy_basic_auth: Sets the string authorization header for <tt>'Proxy-Authorization'</tt>.
-# - #set_range: Sets the value for field <tt>'Range'</tt>.

-# === Form Setters
-#
-# - #set_form: Sets an HTML form data set.
-# - #set_form_data: Sets header fields and a body from HTML form data.
-#
-# === Getters
-#
-# \Method #[] can retrieve the value of any field that exists,
-# but always as a string;
-# some of the other getter methods return something different
-# from the simple string value:
-#
-# - #[]: Returns the string field value for the given key.
-# - #content_length: Returns the integer value of field <tt>'Content-Length'</tt>.
-# - #content_range: Returns the Range value of field <tt>'Content-Range'</tt>.
-# - #content_type: Returns the string value of field <tt>'Content-Type'</tt>.
-# - #fetch: Returns the string field value for the given key.
-# - #get_fields: Returns the array field value for the given +key+.
-# - #main_type: Returns first part of the string value of field <tt>'Content-Type'</tt>.
-# - #sub_type: Returns second part of the string value of field <tt>'Content-Type'</tt>.
-# - #range: Returns an array of Range objects of field <tt>'Range'</tt>, or +nil+.
-# - #range_length: Returns the integer length of the range given in field <tt>'Content-Range'</tt>.
-# - #type_params: Returns the string parameters for <tt>'Content-Type'</tt>.
-#
-# === Queries
-#
-# - #chunked?: Returns whether field <tt>'Transfer-Encoding'</tt> is set to <tt>'chunked'</tt>.
-# - #connection_close?: Returns whether field <tt>'Connection'</tt> is set to <tt>'close'</tt>.
-# - #connection_keep_alive?: Returns whether field <tt>'Connection'</tt> is set to <tt>'keep-alive'</tt>.
-# - #key?: Returns whether a given key exists.
-#
-# === Iterators
-#
-# - #each_capitalized: Passes each field capitalized-name/value pair to the block.
-# - #each_capitalized_name: Passes each capitalized field name to the block.
-# - #each_header: Passes each field name/value pair to the block.
-# - #each_name: Passes each field name to the block.
-# - #each_value: Passes each string field value to the block.

-# This class is the base class for \Net::HTTP request classes.
-# The class should not be used directly;
-# instead you should use its subclasses, listed below.
-#
-# == Creating a Request
-#
-# An request object may be created with either a URI or a string hostname:
-#
-#   require 'net/http'
-#   uri = URI('https://jsonplaceholder.typicode.com/')
-#   req = Net::HTTP::Get.new(uri)          # => #<Net::HTTP::Get GET>
-#   req = Net::HTTP::Get.new(uri.hostname) # => #<Net::HTTP::Get GET>
-#
-# And with any of the subclasses:
-#
-#   req = Net::HTTP::Head.new(uri) # => #<Net::HTTP::Head HEAD>
-#   req = Net::HTTP::Post.new(uri) # => #<Net::HTTP::Post POST>
-#   req = Net::HTTP::Put.new(uri)  # => #<Net::HTTP::Put PUT>
-#   # ...
-#
-# The new instance is suitable for use as the argument to Net::HTTP#request.
-#
-# == Request Headers
-#
-# A new request object has these header fields by default:
-#
-#   req.to_hash
-#   # =>
-#   {"accept-encoding"=>["gzip;q=1.0,deflate;q=0.6,identity;q=0.3"],
-#   "accept"=>["*/*"],
-#   "user-agent"=>["Ruby"],
-#   "host"=>["jsonplaceholder.typicode.com"]}
-#
-# See:
-#
-# - {Request header Accept-Encoding}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Accept-Encoding]
-#   and {Compression and Decompression}[rdoc-ref:Net::HTTP@Compression+and+Decompression].
-# - {Request header Accept}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#accept-request-header].
-# - {Request header User-Agent}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#user-agent-request-header].
-# - {Request header Host}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#host-request-header].
-#
-# You can add headers or override default headers:
-#
-#   #   res = Net::HTTP::Get.new(uri, {'foo' => '0', 'bar' => '1'})
-#
-# This class (and therefore its subclasses) also includes (indirectly)
-# module Net::HTTPHeader, which gives access to its
-# {methods for setting headers}[rdoc-ref:Net::HTTPHeader@Setters].
-#
-# == Request Subclasses
-#
-# Subclasses for HTTP requests:
-#
-# - Net::HTTP::Get
-# - Net::HTTP::Head
-# - Net::HTTP::Post
-# - Net::HTTP::Put
-# - Net::HTTP::Delete

-# This class is the base class for \Net::HTTP response classes.
-#
-# == About the Examples
-#
-# :include: doc/net-http/examples.rdoc
-#
-# == Returned Responses
-#
-# \Method Net::HTTP.get_response returns
-# an instance of one of the subclasses of \Net::HTTPResponse:
-#
-#   Net::HTTP.get_response(uri)
-#   # => #<Net::HTTPOK 200 OK readbody=true>
-#   Net::HTTP.get_response(hostname, '/nosuch')
-#   # => #<Net::HTTPNotFound 404 Not Found readbody=true>
-#
-# As does method Net::HTTP#request:
-#
-#   req = Net::HTTP::Get.new(uri)
-#   Net::HTTP.start(hostname) do |http|
-#     http.request(req)
-#   end # => #<Net::HTTPOK 200 OK readbody=true>
-#
-# \Class \Net::HTTPResponse includes module Net::HTTPHeader,
-# which provides access to response header values via (among others):
-#
-# - \Hash-like method <tt>[]</tt>.
-# - Specific reader methods, such as +content_type+.
-#
-# Examples:
-#
-#   res = Net::HTTP.get_response(uri) # => #<Net::HTTPOK 200 OK readbody=true>
-#   res['Content-Type']               # => "text/html; charset=UTF-8"
-#   res.content_type                  # => "text/html"
-#
-# == Response Subclasses
-#
-# \Class \Net::HTTPResponse has a subclass for each
-# {HTTP status code}[https://en.wikipedia.org/wiki/List_of_HTTP_status_codes].
-# You can look up the response class for a given code:
-#
-#   Net::HTTPResponse::CODE_TO_OBJ['200'] # => Net::HTTPOK
-#   Net::HTTPResponse::CODE_TO_OBJ['400'] # => Net::HTTPBadRequest
-#   Net::HTTPResponse::CODE_TO_OBJ['404'] # => Net::HTTPNotFound
-#
-# And you can retrieve the status code for a response object:
-#
-#   Net::HTTP.get_response(uri).code                 # => "200"
-#   Net::HTTP.get_response(hostname, '/nosuch').code # => "404"
-#
-# The response subclasses (indentation shows class hierarchy):
+# frozen_string_literal: false
+# HTTP response class.
 #
-# - Net::HTTPUnknownResponse (for unhandled \HTTP extensions).
+# This class wraps together the response header and the response body (the
+# entity requested).
 #
-# - Net::HTTPInformation:
+# It mixes in the HTTPHeader module, which provides access to response
+# header values both via hash-like methods and via individual readers.
 #
-#   - Net::HTTPContinue (100)
-#   - Net::HTTPSwitchProtocol (101)
-#   - Net::HTTPProcessing (102)
-#   - Net::HTTPEarlyHints (103)
+# Note that each possible HTTP response code defines its own
+# HTTPResponse subclass. All classes are defined under the Net module.
+# Indentation indicates inheritance.  For a list of the classes see Net::HTTP.

-  # it must begin with a shell reserved word, begin with a special built-in,
-  # or contain meta characters:
-  #
-  #   Open3.capture2e('if true; then echo "Foo"; fi') # Shell reserved word.
-  #   # => ["Foo\n", #<Process::Status: pid 2371740 exit 0>]

-  # the pattern is the <tt>ConstantPathNode[...]</tt> expression.
-  #
-  # The pattern gets compiled into an object that responds to #call by running
-  # the #compile method. This method itself will run back through Prism to
-  # parse the expression into a tree, then walk the tree to generate the
-  # necessary callable objects. For example, if you wanted to compile the
-  # expression above into a callable, you would:
-  #
-  #     callable = Prism::Pattern.new("ConstantPathNode[ConstantReadNode[name: :Prism], ConstantReadNode[name: :Pattern]]").compile
-  #     callable.call(node)
-  #
-  # The callable object returned by #compile is guaranteed to respond to #call
-  # with a single argument, which is the node to match against. It also is
-  # guaranteed to respond to #===, which means it itself can be used in a `case`
-  # expression, as in:
-  #
-  #     case node
-  #     when callable
-  #     end
-  #
-  # If the query given to the initializer cannot be compiled into a valid
-  # matcher (either because of a syntax error or because it is using syntax we
-  # do not yet support) then a Prism::Pattern::CompilationError will be
-  # raised.
-  class Pattern
-    # Raised when the query given to a pattern is either invalid Ruby syntax or
-    # is using syntax that we don't yet support.
-    class CompilationError < StandardError
-      # Create a new CompilationError with the given representation of the node
-      # that caused the error.

 require "digest"
 
-# \PStore implements a file based persistence mechanism based on a Hash.
-# User code can store hierarchies of Ruby objects (values)
-# into the data store by name (keys).
-# An object hierarchy may be just a single object.
-# User code may later read values back from the data store
-# or even update data, as needed.
 #
-# The transactional behavior ensures that any changes succeed or fail together.
-# This can be used to ensure that the data store is not left in a transitory state,
-# where some values were updated but others were not.
-#
-# Behind the scenes, Ruby objects are stored to the data store file with Marshal.
-# That carries the usual limitations. Proc objects cannot be marshalled,
-# for example.
-#
-# There are three important concepts here (details at the links):
-#
-# - {Store}[rdoc-ref:PStore@The+Store]: a store is an instance of \PStore.
-# - {Entries}[rdoc-ref:PStore@Entries]: the store is hash-like;
-#   each entry is the key for a stored object.
-# - {Transactions}[rdoc-ref:PStore@Transactions]: each transaction is a collection
-#   of prospective changes to the store;
-#   a transaction is defined in the block given with a call
-#   to PStore#transaction.
-#
-# == About the Examples
-#
-# Examples on this page need a store that has known properties.
-# They can get a new (and populated) store by calling thus:
-#
-#   example_store do |store|
-#     # Example code using store goes here.
-#   end
-#
-# All we really need to know about +example_store+
-# is that it yields a fresh store with a known population of entries;
-# its implementation:
-#
-#   require 'pstore'
-#   require 'tempfile'
-#   # Yield a pristine store for use in examples.
-#   def example_store
-#     # Create the store in a temporary file.
-#     Tempfile.create do |file|
-#       store = PStore.new(file)
-#       # Populate the store.
-#       store.transaction do
-#         store[:foo] = 0
-#         store[:bar] = 1
-#         store[:baz] = 2
-#       end
-#       yield store
-#     end
-#   end
-#
-# == The Store
-#
-# The contents of the store are maintained in a file whose path is specified
-# when the store is created (see PStore.new).
-# The objects are stored and retrieved using
-# module Marshal, which means that certain objects cannot be added to the store;
-# see {Marshal::dump}[rdoc-ref:Marshal.dump].
-#
-# == Entries
-#
-# A store may have any number of entries.
-# Each entry has a key and a value, just as in a hash:
-#
-# - Key: as in a hash, the key can be (almost) any object;
-#   see {Hash Keys}[rdoc-ref:Hash@Hash+Keys].
-#   You may find it convenient to keep it simple by using only
-#   symbols or strings as keys.
-# - Value: the value may be any object that can be marshalled by \Marshal
-#   (see {Marshal::dump}[rdoc-ref:Marshal.dump])
-#   and in fact may be a collection
-#   (e.g., an array, a hash, a set, a range, etc).
-#   That collection may in turn contain nested objects,
-#   including collections, to any depth;
-#   those objects must also be \Marshal-able.
-#   See {Hierarchical Values}[rdoc-ref:PStore@Hierarchical+Values].
-#
-# == Transactions
-#
-# === The Transaction Block
-#
-# The block given with a call to method #transaction#
-# contains a _transaction_,
-# which consists of calls to \PStore methods that
-# read from or write to the store
-# (that is, all \PStore methods except #transaction itself,
-# #path, and Pstore.new):
-#
-#   example_store do |store|
-#     store.transaction do
-#       store.keys # => [:foo, :bar, :baz]
-#       store[:bat] = 3
-#       store.keys # => [:foo, :bar, :baz, :bat]
-#     end
-#   end
-#
-# Execution of the transaction is deferred until the block exits,
-# and is executed _atomically_ (all-or-nothing):
-# either all transaction calls are executed, or none are.
-# This maintains the integrity of the store.
-#
-# Other code in the block (including even calls to #path and PStore.new)
-# is executed immediately, not deferred.
-#
-# The transaction block:
-#
-# - May not contain a nested call to #transaction.
-# - Is the only context where methods that read from or write to
-#   the store are allowed.
-#
-# As seen above, changes in a transaction are made automatically
-# when the block exits.
-# The block may be exited early by calling method #commit or #abort.
-#
-# - Method #commit triggers the update to the store and exits the block:
-#
-#     example_store do |store|
-#       store.transaction do
-#         store.keys # => [:foo, :bar, :baz]
-#         store[:bat] = 3
-#         store.commit
-#         fail 'Cannot get here'
-#       end
-#       store.transaction do
-#         # Update was completed.
-#         store.keys # => [:foo, :bar, :baz, :bat]
-#       end
-#     end
-#
-# - Method #abort discards the update to the store and exits the block:
-#
-#     example_store do |store|
-#       store.transaction do
-#         store.keys # => [:foo, :bar, :baz]
-#         store[:bat] = 3
-#         store.abort
-#         fail 'Cannot get here'
-#       end
-#       store.transaction do
-#         # Update was not completed.
-#         store.keys # => [:foo, :bar, :baz]
-#       end
-#     end
-#
-# === Read-Only Transactions
-#
-# By default, a transaction allows both reading from and writing to
-# the store:
-#
-#   store.transaction do
-#     # Read-write transaction.
-#     # Any code except a call to #transaction is allowed here.
-#   end
-#
-# If argument +read_only+ is passed as +true+,
-# only reading is allowed:
-#
-#   store.transaction(true) do
-#     # Read-only transaction:
-#     # Calls to #transaction, #[]=, and #delete are not allowed here.
-#   end
-#
-# == Hierarchical Values
-#
-# The value for an entry may be a simple object (as seen above).
-# It may also be a hierarchy of objects nested to any depth:
-#
-#   deep_store = PStore.new('deep.store')
-#   deep_store.transaction do
-#     array_of_hashes = [{}, {}, {}]
-#     deep_store[:array_of_hashes] = array_of_hashes
-#     deep_store[:array_of_hashes] # => [{}, {}, {}]
-#     hash_of_arrays = {foo: [], bar: [], baz: []}
-#     deep_store[:hash_of_arrays] = hash_of_arrays
-#     deep_store[:hash_of_arrays]  # => {:foo=>[], :bar=>[], :baz=>[]}
-#     deep_store[:hash_of_arrays][:foo].push(:bat)
-#     deep_store[:hash_of_arrays]  # => {:foo=>[:bat], :bar=>[], :baz=>[]}
-#   end
-#
-# And recall that you can use
-# {dig methods}[rdoc-ref:dig_methods.rdoc]
-# in a returned hierarchy of objects.
-#
-# == Working with the Store
-#
-# === Creating a Store
-#
-# Use method PStore.new to create a store.
-# The new store creates or opens its containing file:
-#
-#   store = PStore.new('t.store')
-#
-# === Modifying the Store
-#
-# Use method #[]= to update or create an entry:
-#
-#   example_store do |store|
-#     store.transaction do
-#       store[:foo] = 1 # Update.
-#       store[:bam] = 1 # Create.
-#     end
-#   end
-#
-# Use method #delete to remove an entry:
-#
-#   example_store do |store|
-#     store.transaction do
-#       store.delete(:foo)
-#       store[:foo] # => nil
-#     end
-#   end
-#
-# === Retrieving Values
-#
-# Use method #fetch (allows default) or #[] (defaults to +nil+)
-# to retrieve an entry:
-#
-#   example_store do |store|
-#     store.transaction do
-#       store[:foo]             # => 0
-#       store[:nope]            # => nil
-#       store.fetch(:baz)       # => 2
-#       store.fetch(:nope, nil) # => nil
-#       store.fetch(:nope)      # Raises exception.
-#     end
-#   end
-#
-# === Querying the Store
-#
-# Use method #key? to determine whether a given key exists:
-#
-#   example_store do |store|
-#     store.transaction do
-#       store.key?(:foo) # => true
-#     end
-#   end
+# PStore implements a file based persistence mechanism based on a Hash.  User
+# code can store hierarchies of Ruby objects (values) into the data store file
+# by name (keys).  An object hierarchy may be just a single object.  User code
+# may later read values back from the data store or even update data, as needed.
 #
-# Use method #keys to retrieve keys:
-#
-#   example_store do |store|
-#     store.transaction do
-#       store.keys # => [:foo, :bar, :baz]
-#     end
-#   end
-#
-# Use method #path to retrieve the path to the store's underlying file;
-# this method may be called from outside a transaction block:
-#
-#   store = PStore.new('t.store')
-#   store.path # => "t.store"
-#
-# == Transaction Safety
-#
-# For transaction safety, see:
-#
-# - Optional argument +thread_safe+ at method PStore.new.
-# - Attribute #ultra_safe.
+# The transactional behavior ensures that any changes succeed or fail together.
+# This can be used to ensure that the data store is not left in a transitory
+# state, where some values were updated but others were not.
 #
-# Needless to say, if you're storing valuable data with \PStore, then you should
-# backup the \PStore file from time to time.
+# Behind the scenes, Ruby objects are stored to the data store file with
+# Marshal.  That carries the usual limitations.  Proc objects cannot be
+# marshalled, for example.
 #
-# == An Example Store
+# == Usage example:
 #
 #  require "pstore"
 #
-#  # A mock wiki object.
+#  # a mock wiki object...
 #  class WikiPage
-#
-#    attr_reader :page_name
-#
-#    def initialize(page_name, author, contents)
+#    def initialize( page_name, author, contents )
 #      @page_name = page_name
 #      @revisions = Array.new
+#
 #      add_revision(author, contents)
 #    end
 #
-#    def add_revision(author, contents)
-#      @revisions << {created: Time.now,
-#                     author: author,
-#                     contents: contents}
+#    attr_reader :page_name
+#
+#    def add_revision( author, contents )
+#      @revisions << { :created  => Time.now,
+#                      :author   => author,
+#                      :contents => contents }
 #    end
 #
 #    def wiki_page_references
 #      [@page_name] + @revisions.last[:contents].scan(/\b(?:[A-Z]+[a-z]+){2,}/)
 #    end
 #
+#    # ...
 #  end
 #
-#  # Create a new wiki page.
-#  home_page = WikiPage.new("HomePage", "James Edward Gray II",
-#                           "A page about the JoysOfDocumentation..." )

 #
+#  # then we want to update page data and the index together, or not at all...
 #  wiki = PStore.new("wiki_pages.pstore")
-#  # Update page data and the index together, or not at all.
-#  wiki.transaction do
-#    # Store page.
+#  wiki.transaction do  # begin transaction; do all of this or none of it

 #    wiki[home_page.page_name] = home_page
-#    # Create page index.
+#    # ensure that an index has been created...
 #    wiki[:wiki_index] ||= Array.new
-#    # Update wiki index.
+#    # update wiki index...
 #    wiki[:wiki_index].push(*home_page.wiki_page_references)
-#  end
+#  end                   # commit changes to wiki data store file
+#
+#  ### Some time later... ###
 #
-#  # Read wiki data, setting argument read_only to true.
-#  wiki.transaction(true) do
-#    wiki.keys.each do |key|
-#      puts key
-#      puts wiki[key]
+#  # read wiki data...
+#  wiki.transaction(true) do  # begin read-only transaction, no changes allowed
+#    wiki.roots.each do |data_root_name|
+#      p data_root_name
+#      p wiki[data_root_name]
 #    end
 #  end
 #
+# == Transaction modes
+#
+# By default, file integrity is only ensured as long as the operating system
+# (and the underlying hardware) doesn't raise any unexpected I/O errors. If an
+# I/O error occurs while PStore is writing to its file, then the file will
+# become corrupted.
+#
+# You can prevent this by setting <em>pstore.ultra_safe = true</em>.
+# However, this results in a minor performance loss, and only works on platforms
+# that support atomic file renames. Please consult the documentation for
+# +ultra_safe+ for details.
+#
+# Needless to say, if you're storing valuable data with PStore, then you should
+# backup the PStore files from time to time.

+# == Generating Parser Using Racc
+#
+# To compile Racc grammar file, simply type:
+#
+#   $ racc parse.y
+#
+# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
+#
+# == Writing A Racc Grammar File
+#
+# If you want your own parser, you have to write a grammar file.
+# A grammar file contains the name of your parser class, grammar for the parser,
+# user code, and anything else.
+# When writing a grammar file, yacc's knowledge is helpful.
+# If you have not used yacc before, Racc is not too difficult.
+#
+# Here's an example Racc grammar file.
+#
+#   class Calcparser
+#   rule
+#     target: exp { print val[0] }
+#
+#     exp: exp '+' exp
+#        | exp '*' exp
+#        | '(' exp ')'
+#        | NUMBER
+#   end
+#
+# Racc grammar files resemble yacc files.
+# But (of course), this is Ruby code.
+# yacc's $$ is the 'result', $0, $1... is
+# an array called 'val', and $-1, $-2... is an array called '_values'.
+#
+# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
+# more information on grammar files.
+#
+# == Parser
+#
+# Then you must prepare the parse entry method. There are two types of
+# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
+#
+# Racc::Parser#do_parse is simple.
+#
+# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
+# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
+# EOF is [false, false].
+# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
+# If you want to change this, see the grammar reference.
+#
+# Racc::Parser#yyparse is little complicated, but useful.
+# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
+#
+# For example, <code>yyparse(obj, :scan)</code> causes
+# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
+#
+# == Debugging
+#
+# When debugging, "-v" or/and the "-g" option is helpful.
+#
+# "-v" creates verbose log file (.output).
+# "-g" creates a "Verbose Parser".
+# Verbose Parser prints the internal status when parsing.
+# But it's _not_ automatic.
+# You must use -g option and set +@yydebug+ to +true+ in order to get output.
+# -g option only creates the verbose parser.
+#
+# === Racc reported syntax error.
+#
+# Isn't there too many "end"?
+# grammar of racc file is changed in v0.10.
+#
+# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
+#
+# === Racc reported "XXXX conflicts".
+#
+# Try "racc -v xxxx.y".
+# It causes producing racc's internal log file, xxxx.output.
+#
+# === Generated parsers does not work correctly
+#

+# == Re-distributing Racc runtime
+#
+# A parser, which is created by Racc, requires the Racc runtime module;
+# racc/parser.rb.
+#
+# Ruby 1.8.x comes with Racc runtime module,
+# you need NOT distribute Racc runtime files.
+#
+# If you want to include the Racc runtime module with your parser.
+# This can be done by using '-E' option:
+#
+#   $ racc -E -omyparser.rb myparser.y
+#
+# This command creates myparser.rb which `includes' Racc runtime.
+# Only you must do is to distribute your parser file (myparser.rb).
+#
+# Note: parser.rb is ruby license, but your parser is not.
+# Your own parser is completely yours.

+#
+# == Generating Parser Using Racc
+#
+# To compile Racc grammar file, simply type:
+#
+#   $ racc parse.y
+#
+# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
+#
+# == Writing A Racc Grammar File
+#
+# If you want your own parser, you have to write a grammar file.
+# A grammar file contains the name of your parser class, grammar for the parser,
+# user code, and anything else.
+# When writing a grammar file, yacc's knowledge is helpful.
+# If you have not used yacc before, Racc is not too difficult.
+#
+# Here's an example Racc grammar file.
+#
+#   class Calcparser
+#   rule
+#     target: exp { print val[0] }
+#
+#     exp: exp '+' exp
+#        | exp '*' exp
+#        | '(' exp ')'
+#        | NUMBER
+#   end
+#
+# Racc grammar files resemble yacc files.
+# But (of course), this is Ruby code.
+# yacc's $$ is the 'result', $0, $1... is
+# an array called 'val', and $-1, $-2... is an array called '_values'.
+#
+# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
+# more information on grammar files.
+#
+# == Parser
+#
+# Then you must prepare the parse entry method. There are two types of
+# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
+#
+# Racc::Parser#do_parse is simple.
+#
+# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
+# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
+# EOF is [false, false].
+# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
+# If you want to change this, see the grammar reference.
+#
+# Racc::Parser#yyparse is little complicated, but useful.
+# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
+#
+# For example, <code>yyparse(obj, :scan)</code> causes
+# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
+#
+# == Debugging
+#
+# When debugging, "-v" or/and the "-g" option is helpful.
+#
+# "-v" creates verbose log file (.output).
+# "-g" creates a "Verbose Parser".
+# Verbose Parser prints the internal status when parsing.
+# But it's _not_ automatic.
+# You must use -g option and set +@yydebug+ to +true+ in order to get output.
+# -g option only creates the verbose parser.
+#
+# === Racc reported syntax error.
+#
+# Isn't there too many "end"?
+# grammar of racc file is changed in v0.10.
+#
+# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
+#
+# === Racc reported "XXXX conflicts".
+#
+# Try "racc -v xxxx.y".
+# It causes producing racc's internal log file, xxxx.output.
+#
+# === Generated parsers does not work correctly
+#
+# Try "racc -g xxxx.y".
+# This command let racc generate "debugging parser".
+# Then set @yydebug=true in your parser.
+# It produces a working log of your parser.
+#
+# == Re-distributing Racc runtime
+#
+# A parser, which is created by Racc, requires the Racc runtime module;
+# racc/parser.rb.
+#
+# Ruby 1.8.x comes with Racc runtime module,
+# you need NOT distribute Racc runtime files.
+#
+# If you want to include the Racc runtime module with your parser.
+# This can be done by using '-E' option:
+#
+#   $ racc -E -omyparser.rb myparser.y
+#
+# This command creates myparser.rb which `includes' Racc runtime.
+# Only you must do is to distribute your parser file (myparser.rb).
+#
+# Note: parser.rb is ruby license, but your parser is not.
+# Your own parser is completely yours.

 #
 # = \RDoc Markup Reference
 #
-# See RDoc::MarkupReference.
+# == Block Markup
+#
+# === Paragraphs and Verbatim
+#
+# The markup engine looks for a document's natural left margin.  This is
+# used as the initial margin for the document.
+#
+# Consecutive lines starting at this margin are considered to be a
+# paragraph. Empty lines separate paragraphs.
+#
+# Any line that starts to the right of the current margin is treated
+# as verbatim text.  This is useful for code listings:
+#
+#   3.times { puts "Ruby" }
+#
+# In verbatim text, two or more blank lines are collapsed into one,
+# and trailing blank lines are removed:
+#
+#   This is the first line
+#
+#
+#   This is the second non-blank line,
+#   after 2 blank lines in the source markup.
+#
+#
+# There were two trailing blank lines right above this paragraph, that
+# have been removed. In addition, the verbatim text has been shifted
+# left, so the amount of indentation of verbatim text is unimportant.
+#
+# For HTML output RDoc makes a small effort to determine if a verbatim section
+# contains Ruby source code.  If so, the verbatim block will be marked up as
+# HTML.  Triggers include "def", "class", "module", "require", the "hash
+# rocket"# (=>) or a block call with a parameter.
+#
+# === Headers
+#
+# A line starting with an equal sign (=) is treated as a
+# heading.  Level one headings have one equals sign, level two headings
+# have two, and so on until level six, which is the maximum
+# (seven hyphens or more result in a level six heading).
+#
+# For example, the above header was obtained with:
+#
+#   === Headers
+#
+# In HTML output headers have an id matching their name.  The above example's
+# HTML is:
+#
+#   <h3 id="label-Headers">Headers</h3>
+#
+# If a heading is inside a method body the id will be prefixed with the
+# method's id.  If the above header where in the documentation for a method
+# such as:
+#
+#   ##
+#   # This method does fun things
+#   #
+#   # = Example
+#   #
+#   #   Example of fun things goes here ...
+#
+#   def do_fun_things
+#   end
+#
+# The header's id would be:
+#
+#   <h1 id="method-i-do_fun_things-label-Example">Example</h1>
+#
+# The label can be linked-to using <tt>SomeClass@Headers</tt>.  See
+# {Links}[RDoc::Markup@Links] for further details.
+#
+# === Rules
+#
+# A line starting with three or more hyphens (at the current indent)
+# generates a horizontal rule.
+#
+#   ---
+#
+# produces:
+#
+# ---
+#
+# === Simple Lists
+#
+# If a paragraph starts with a "*", "-", "<digit>." or "<letter>.",
+# then it is taken to be the start of a list.  The margin is increased to be
+# the first non-space following the list start flag.  Subsequent lines
+# should be indented to this new margin until the list ends.  For example:
+#
+#   * this is a list with three paragraphs in
+#     the first item.  This is the first paragraph.
+#
+#     And this is the second paragraph.
+#
+#     1. This is an indented, numbered list.
+#     2. This is the second item in that list
+#
+#     This is the third conventional paragraph in the
+#     first list item.
+#
+#   * This is the second item in the original list
+#
+# produces:
+#
+# * this is a list with three paragraphs in
+#   the first item.  This is the first paragraph.
+#
+#   And this is the second paragraph.
+#
+#   1. This is an indented, numbered list.
+#   2. This is the second item in that list
+#
+#   This is the third conventional paragraph in the
+#   first list item.
+#
+# * This is the second item in the original list
+#
+# === Labeled Lists
+#
+# You can also construct labeled lists, sometimes called description
+# or definition lists.  Do this by putting the label in square brackets
+# and indenting the list body:
+#
+#   [cat]  a small furry mammal
+#          that seems to sleep a lot
+#
+#   [ant]  a little insect that is known
+#          to enjoy picnics
+#
+# produces:
+#
+# [cat]  a small furry mammal
+#        that seems to sleep a lot
+#
+# [ant]  a little insect that is known
+#        to enjoy picnics
+#
+# If you want the list bodies to line up to the left of the labels,
+# use two colons:
+#
+#   cat::  a small furry mammal
+#          that seems to sleep a lot
+#
+#   ant::  a little insect that is known
+#          to enjoy picnics
+#
+# produces:
+#
+# cat::  a small furry mammal
+#        that seems to sleep a lot
+#
+# ant::  a little insect that is known
+#        to enjoy picnics
+#
+# Notice that blank lines right after the label are ignored in labeled lists:
+#
+#   [one]
+#
+#       definition 1
+#
+#   [two]
+#
+#       definition 2
+#
+# produces the same output as
+#
+#   [one]  definition 1
+#   [two]  definition 2
+#
+#
+# === Lists and Verbatim
+#
+# If you want to introduce a verbatim section right after a list, it has to be
+# less indented than the list item bodies, but more indented than the list
+# label, letter, digit or bullet. For instance:
+#
+#   *   point 1
+#
+#   *   point 2, first paragraph
+#
+#       point 2, second paragraph
+#         verbatim text inside point 2
+#       point 2, third paragraph
+#     verbatim text outside of the list (the list is therefore closed)
+#   regular paragraph after the list
+#
+# produces:
+#
+# *   point 1
+#
+# *   point 2, first paragraph
+#
+#     point 2, second paragraph
+#       verbatim text inside point 2
+#     point 2, third paragraph
+#   verbatim text outside of the list (the list is therefore closed)
+# regular paragraph after the list
+#
+# == Text Markup
+#
+# === Bold, Italic, Typewriter Text
+#
+# You can use markup within text (except verbatim) to change the
+# appearance of parts of that text.  Out of the box, RDoc::Markup
+# supports word-based and general markup.
+#
+# Word-based markup uses flag characters around individual words:
+#
+# <tt>\*_word_\*</tt>::  displays _word_ in a *bold* font
+# <tt>\__word_\_</tt>::  displays _word_ in an _emphasized_ font
+# <tt>\+_word_\+</tt>::  displays _word_ in a +code+ font
+#
+# General markup affects text between a start delimiter and an end
+# delimiter.  Not surprisingly, these delimiters look like HTML markup.
+#
+# <tt>\<b>_text_</b></tt>::    displays _text_ in a *bold* font
+# <tt>\<em>_text_</em></tt>::  displays _text_ in an _emphasized_ font
+#                              (alternate tag: <tt>\<i></tt>)
+# <tt>\<tt>_text_\</tt></tt>:: displays _text_ in a +code+ font
+#                              (alternate tag: <tt>\<code></tt>)
+#
+# Unlike conventional Wiki markup, general markup can cross line
+# boundaries.  You can turn off the interpretation of markup by
+# preceding the first character with a backslash (see <i>Escaping
+# Text Markup</i>, below).
+#
+# === Links
+#
+# Links to starting with +http:+, +https:+, +mailto:+, +ftp:+ or +www.+
+# are recognized.  An HTTP url that references an external image is converted
+# into an inline image element.
+#
+# Classes and methods will be automatically linked to their definition.  For
+# example, <tt>RDoc::Markup</tt> will link to this documentation.  By default
+# methods will only be automatically linked if they contain an <tt>_</tt> (all
+# methods can be automatically linked through the <tt>--hyperlink-all</tt>
+# command line option).
+#
+# Single-word methods can be linked by using the <tt>#</tt> character for
+# instance methods or <tt>::</tt> for class methods.  For example,
+# <tt>#convert</tt> links to #convert.  A class or method may be combined like
+# <tt>RDoc::Markup#convert</tt>.
+#
+# A heading inside the documentation can be linked by following the class
+# or method by an <tt>@</tt> then the heading name.
+# <tt>RDoc::Markup@Links</tt> will link to this section like this:
+# RDoc::Markup@Links.  Spaces in headings with multiple words must be escaped
+# with <tt>+</tt> like <tt>RDoc::Markup@Escaping+Text+Markup</tt>.
+# Punctuation and other special characters must be escaped like CGI.escape.
+#
+# The <tt>@</tt> can also be used to link to sections.  If a section and a
+# heading share the same name the section is preferred for the link.
+#
+# Links can also be of the form <tt>label[url]</tt>, in which case +label+ is
+# used in the displayed text, and +url+ is used as the target.  If +label+
+# contains multiple words, put it in braces: <tt>{multi word label}[url]</tt>.
+# The +url+ may be an +http:+-type link or a cross-reference to a class,
+# module or method with a label.
+#
+# Links with the <code>rdoc-image:</code> scheme will create an image tag for
+# HTML output.  Only fully-qualified URLs are supported.
+#
+# Links with the <tt>rdoc-ref:</tt> scheme will link to the referenced class,
+# module, method, file, etc.  If the referenced item is does not exist
+# no link will be generated and <tt>rdoc-ref:</tt> will be removed from the
+# resulting text.
+#
+# Links starting with <tt>rdoc-label:label_name</tt> will link to the
+# +label_name+.  You can create a label for the current link (for
+# bidirectional links) by supplying a name for the current link like
+# <tt>rdoc-label:label-other:label-mine</tt>.
+#
+# Links starting with +link:+ refer to local files whose path is relative to
+# the <tt>--op</tt> directory.  Use <tt>rdoc-ref:</tt> instead of
+# <tt>link:</tt> to link to files generated by RDoc as the link target may
+# be different across RDoc generators.
+#
+# Example links:
+#
+#   https://github.com/ruby/rdoc

+#   {RDoc Markup}[rdoc-ref:RDoc::Markup]
+#
+# === Escaping Text Markup
+#
+# Text markup can be escaped with a backslash, as in \<tt>, which was obtained
+# with <tt>\\<tt></tt>.  Except in verbatim sections and between \<tt> tags,
+# to produce a backslash you have to double it unless it is followed by a
+# space, tab or newline. Otherwise, the HTML formatter will discard it, as it
+# is used to escape potential links:
+#
+#   * The \ must be doubled if not followed by white space: \\.
+#   * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
+#   * This is a link to {ruby-lang}[www.ruby-lang.org].
+#   * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org].
+#   * This will not be linked to \RDoc::RDoc#document
+#
+# generates:
+#
+# * The \ must be doubled if not followed by white space: \\.
+# * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
+# * This is a link to {ruby-lang}[www.ruby-lang.org]
+# * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org]
+# * This will not be linked to \RDoc::RDoc#document
+#
+# Inside \<tt> tags, more precisely, leading backslashes are removed only if
+# followed by a markup character (<tt><*_+</tt>), a backslash, or a known link
+# reference (a known class or method). So in the example above, the backslash
+# of <tt>\S</tt> would be removed if there was a class or module named +S+ in
+# the current context.
+#
+# This behavior is inherited from RDoc version 1, and has been kept for
+# compatibility with existing RDoc documentation.
+#
+# === Conversion of characters
+#
+# HTML will convert two/three dashes to an em-dash. Other common characters are
+# converted as well:
+#
+#   em-dash::  -- or ---
+#   ellipsis:: ...
+#
+#   single quotes:: 'text' or `text'
+#   double quotes:: "text" or ``text''
+#
+#   copyright:: (c)
+#   registered trademark:: (r)
+#
+# produces:
+#
+# em-dash::  -- or ---
+# ellipsis:: ...
+#
+# single quotes:: 'text' or `text'
+# double quotes:: "text" or ``text''
+#
+# copyright:: (c)
+# registered trademark:: (r)
+#
+#
+# == Documenting Source Code
+#
+# Comment blocks can be written fairly naturally, either using <tt>#</tt> on
+# successive lines of the comment, or by including the comment in
+# a <tt>=begin</tt>/<tt>=end</tt> block.  If you use the latter form,
+# the <tt>=begin</tt> line _must_ be flagged with an +rdoc+ tag:
+#
+#   =begin rdoc
+#   Documentation to be processed by RDoc.
+#
+#   ...
+#   =end
+#
+# RDoc stops processing comments if it finds a comment line starting
+# with <tt>--</tt> right after the <tt>#</tt> character (otherwise,
+# it will be treated as a rule if it has three dashes or more).
+# This can be used to separate external from internal comments,
+# or to stop a comment being associated with a method, class, or module.
+# Commenting can be turned back on with a line that starts with <tt>++</tt>.
+#
+#   ##
+#   # Extract the age and calculate the date-of-birth.
+#   #--
+#   # FIXME: fails if the birthday falls on February 29th
+#   #++
+#   # The DOB is returned as a Time object.
+#
+#   def get_dob(person)
+#     # ...
+#   end
+#
+# Names of classes, files, and any method names containing an underscore or
+# preceded by a hash character are automatically linked from comment text to
+# their description. This linking works inside the current class or module,
+# and with ancestor methods (in included modules or in the superclass).
+#
+# Method parameter lists are extracted and displayed with the method
+# description.  If a method calls +yield+, then the parameters passed to yield
+# will also be displayed:
+#
+#   def fred
+#     ...
+#     yield line, address
+#
+# This will get documented as:
+#
+#   fred() { |line, address| ... }
+#
+# You can override this using a comment containing ':yields: ...' immediately
+# after the method definition
+#
+#   def fred # :yields: index, position
+#     # ...
+#
+#     yield line, address
+#
+# which will get documented as
+#
+#    fred() { |index, position| ... }
+#
+# +:yields:+ is an example of a documentation directive.  These appear
+# immediately after the start of the document element they are modifying.
+#
+# RDoc automatically cross-references words with underscores or camel-case.
+# To suppress cross-references, prefix the word with a \ character.  To
+# include special characters like "<tt>\n</tt>", you'll need to use
+# two \ characters in normal text, but only one in \<tt> text:
+#
+#   "\\n" or "<tt>\n</tt>"
+#
+# produces:
+#
+# "\\n" or "<tt>\n</tt>"
+#
+# == Directives
+#
+# Directives are keywords surrounded by ":" characters.
+#
+# === Controlling what is documented
+#
+# [+:nodoc:+ / <tt>:nodoc: all</tt>]
+#   This directive prevents documentation for the element from
+#   being generated.  For classes and modules, methods, aliases,
+#   constants, and attributes directly within the affected class or
+#   module also will be omitted.  By default, though, modules and
+#   classes within that class or module _will_ be documented.  This is
+#   turned off by adding the +all+ modifier.
+#
+#     module MyModule # :nodoc:
+#       class Input
+#       end
+#     end
+#
+#     module OtherModule # :nodoc: all
+#       class Output
+#       end
+#     end
+#
+#   In the above code, only class <tt>MyModule::Input</tt> will be documented.
+#
+#   The +:nodoc:+ directive, like +:enddoc:+, +:stopdoc:+ and +:startdoc:+
+#   presented below, is local to the current file: if you do not want to
+#   document a module that appears in several files, specify +:nodoc:+ on each
+#   appearance, at least once per file.
+#
+# [+:stopdoc:+ / +:startdoc:+]
+#   Stop and start adding new documentation elements to the current container.
+#   For example, if a class has a number of constants that you don't want to
+#   document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the
+#   last.  If you don't specify a +:startdoc:+ by the end of the container,
+#   disables documentation for the rest of the current file.
+#
+# [+:doc:+]
+#   Forces a method or attribute to be documented even if it wouldn't be
+#   otherwise.  Useful if, for example, you want to include documentation of a
+#   particular private method.
+#
+# [+:enddoc:+]
+#   Document nothing further at the current level: directives +:startdoc:+ and
+#   +:doc:+ that appear after this will not be honored for the current container
+#   (file, class or module), in the current file.
+#
+# [+:notnew:+ / +:not_new:+ / +:not-new:+ ]
+#   Only applicable to the +initialize+ instance method.  Normally RDoc
+#   assumes that the documentation and parameters for +initialize+ are
+#   actually for the +new+ method, and so fakes out a +new+ for the class.
+#   The +:notnew:+ directive stops this.  Remember that +initialize+ is private,
+#   so you won't see the documentation unless you use the +-a+ command line
+#   option.
+#
+# === Method arguments
+#
+# [+:arg:+ or +:args:+ _parameters_]
+#   Overrides the default argument handling with exactly these parameters.
+#
+#     ##
+#     #  :args: a, b
+#
+#     def some_method(*a)
+#     end
+#
+# [+:yield:+ or +:yields:+ _parameters_]
+#   Overrides the default yield discovery with these parameters.
+#
+#     ##
+#     # :yields: key, value
+#
+#     def each_thing &block
+#       @things.each(&block)
+#     end
+#
+# [+:call-seq:+]
+#   Lines up to the next blank line or lines with a common prefix in the
+#   comment are treated as the method's calling sequence, overriding the
+#   default parsing of method parameters and yield arguments.
+#
+#   Multiple lines may be used.
+#
+#     # :call-seq:
+#     #   ARGF.readlines(sep=$/)     -> array
+#     #   ARGF.readlines(limit)      -> array
+#     #   ARGF.readlines(sep, limit) -> array
+#     #
+#     #   ARGF.to_a(sep=$/)     -> array
+#     #   ARGF.to_a(limit)      -> array
+#     #   ARGF.to_a(sep, limit) -> array
+#     #
+#     # The remaining lines are documentation ...
+#
+# === Sections
+#
+# Sections allow you to group methods in a class into sensible containers.  If
+# you use the sections 'Public', 'Internal' and 'Deprecated' (the three
+# allowed method statuses from TomDoc) the sections will be displayed in that
+# order placing the most useful methods at the top.  Otherwise, sections will
+# be displayed in alphabetical order.
+#
+# [+:category:+ _section_]
+#   Adds this item to the named +section+ overriding the current section.  Use
+#   this to group methods by section in RDoc output while maintaining a
+#   sensible ordering (like alphabetical).
+#
+#     # :category: Utility Methods
+#     #
+#     # CGI escapes +text+
+#
+#     def convert_string text
+#       CGI.escapeHTML text
+#     end
+#
+#   An empty category will place the item in the default category:
+#
+#     # :category:
+#     #
+#     # This method is in the default category
+#
+#     def some_method
+#       # ...
+#     end
+#
+#   Unlike the :section: directive, :category: is not sticky.  The category
+#   only applies to the item immediately following the comment.
+#
+#   Use the :section: directive to provide introductory text for a section of
+#   documentation.
+#
+# [+:section:+ _title_]
+#   Provides section introductory text in RDoc output.  The title following
+#   +:section:+ is used as the section name and the remainder of the comment
+#   containing the section is used as introductory text.  A section's comment
+#   block must be separated from following comment blocks.  Use an empty title
+#   to switch to the default section.
+#
+#   The :section: directive is sticky, so subsequent methods, aliases,
+#   attributes, and classes will be contained in this section until the
+#   section is changed.  The :category: directive will override the :section:
+#   directive.
+#
+#   A :section: comment block may have one or more lines before the :section:
+#   directive.  These will be removed, and any identical lines at the end of
+#   the block are also removed.  This allows you to add visual cues to 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
+#
+# === Other directives
+#
+# [+:markup:+ _type_]
+#   Overrides the default markup type for this comment with the specified
+#   markup type.  For Ruby files, if the first comment contains this directive
+#   it is applied automatically to all comments in the file.
+#
+#   Unless you are converting between markup formats you should use a
+#   <code>.rdoc_options</code> file to specify the default documentation
+#   format for your entire project.  See RDoc::Options@Saved+Options for
+#   instructions.
+#
+#   At the top of a file the +:markup:+ directive applies to the entire file:
+#
+#     # coding: UTF-8
+#     # :markup: TomDoc
+#
+#     # TomDoc comment here ...
+#
+#     class MyClass
+#       # ...
+#
+#   For just one comment:
+#
+#       # ...
+#     end
+#
+#     # :markup: RDoc
+#     #
+#     # This is a comment in RDoc markup format ...
+#
+#     def some_method
+#       # ...
+#
+#   See Markup@CONTRIBUTING for instructions on adding a new markup format.
+#
+# [+:include:+ _filename_]
+#   Include the contents of the named file at this point. This directive
+#   must appear alone on one line, possibly preceded by spaces. In this
+#   position, it can be escaped with a \ in front of the first colon.
+#
+#   The file will be searched for in the directories listed by the +--include+
+#   option, or in the current directory by default.  The contents of the file
+#   will be shifted to have the same indentation as the ':' at the start of
+#   the +:include:+ directive.
+#
+# [+:title:+ _text_]
+#   Sets the title for the document.  Equivalent to the <tt>--title</tt>
+#   command line parameter.  (The command line parameter overrides any :title:
+#   directive in the source).
+#
+# [+:main:+ _name_]
+#   Equivalent to the <tt>--main</tt> command line parameter.

-# == Generating Parser Using Racc
-#
-# To compile Racc grammar file, simply type:
-#
-#   $ racc parse.y
-#
-# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
-#
-# == Writing A Racc Grammar File
-#
-# If you want your own parser, you have to write a grammar file.
-# A grammar file contains the name of your parser class, grammar for the parser,
-# user code, and anything else.
-# When writing a grammar file, yacc's knowledge is helpful.
-# If you have not used yacc before, Racc is not too difficult.
-#
-# Here's an example Racc grammar file.
-#
-#   class Calcparser
-#   rule
-#     target: exp { print val[0] }
-#
-#     exp: exp '+' exp
-#        | exp '*' exp
-#        | '(' exp ')'
-#        | NUMBER
-#   end
-#
-# Racc grammar files resemble yacc files.
-# But (of course), this is Ruby code.
-# yacc's $$ is the 'result', $0, $1... is
-# an array called 'val', and $-1, $-2... is an array called '_values'.
-#
-# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
-# more information on grammar files.
-#
-# == Parser
-#
-# Then you must prepare the parse entry method. There are two types of
-# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
-#
-# Racc::Parser#do_parse is simple.
-#
-# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
-# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
-# EOF is [false, false].
-# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
-# If you want to change this, see the grammar reference.
-#
-# Racc::Parser#yyparse is little complicated, but useful.
-# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
-#
-# For example, <code>yyparse(obj, :scan)</code> causes
-# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
-#
-# == Debugging
-#
-# When debugging, "-v" or/and the "-g" option is helpful.
-#
-# "-v" creates verbose log file (.output).
-# "-g" creates a "Verbose Parser".
-# Verbose Parser prints the internal status when parsing.
-# But it's _not_ automatic.
-# You must use -g option and set +@yydebug+ to +true+ in order to get output.
-# -g option only creates the verbose parser.
-#
-# === Racc reported syntax error.
-#
-# Isn't there too many "end"?
-# grammar of racc file is changed in v0.10.
-#
-# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
-#
-# === Racc reported "XXXX conflicts".
-#
-# Try "racc -v xxxx.y".
-# It causes producing racc's internal log file, xxxx.output.
-#
-# === Generated parsers does not work correctly
-#
-# Try "racc -g xxxx.y".
-# This command let racc generate "debugging parser".
-# Then set @yydebug=true in your parser.
-# It produces a working log of your parser.
-#
-# == Re-distributing Racc runtime
-#
-# A parser, which is created by Racc, requires the Racc runtime module;
-# racc/parser.rb.
-#
-# Ruby 1.8.x comes with Racc runtime module,
-# you need NOT distribute Racc runtime files.
-#
-# If you want to include the Racc runtime module with your parser.
-# This can be done by using '-E' option:
-#
-#   $ racc -E -omyparser.rb myparser.y
-#
-# This command creates myparser.rb which `includes' Racc runtime.
-# Only you must do is to distribute your parser file (myparser.rb).
-#
-# Note: parser.rb is ruby license, but your parser is not.
-# Your own parser is completely yours.

-#
-# == Generating Parser Using Racc
-#
-# To compile Racc grammar file, simply type:
-#
-#   $ racc parse.y
-#
-# This creates Ruby script file "parse.tab.y". The -o option can change the output filename.
-#
-# == Writing A Racc Grammar File
-#
-# If you want your own parser, you have to write a grammar file.
-# A grammar file contains the name of your parser class, grammar for the parser,
-# user code, and anything else.
-# When writing a grammar file, yacc's knowledge is helpful.
-# If you have not used yacc before, Racc is not too difficult.
-#
-# Here's an example Racc grammar file.
-#
-#   class Calcparser
-#   rule
-#     target: exp { print val[0] }
-#
-#     exp: exp '+' exp
-#        | exp '*' exp
-#        | '(' exp ')'
-#        | NUMBER
-#   end
-#
-# Racc grammar files resemble yacc files.
-# But (of course), this is Ruby code.
-# yacc's $$ is the 'result', $0, $1... is
-# an array called 'val', and $-1, $-2... is an array called '_values'.
-#
-# See the {Grammar File Reference}[rdoc-ref:lib/racc/rdoc/grammar.en.rdoc] for
-# more information on grammar files.
-#
-# == Parser
-#
-# Then you must prepare the parse entry method. There are two types of
-# parse methods in Racc, Racc::Parser#do_parse and Racc::Parser#yyparse
-#
-# Racc::Parser#do_parse is simple.
-#
-# It's yyparse() of yacc, and Racc::Parser#next_token is yylex().
-# This method must returns an array like [TOKENSYMBOL, ITS_VALUE].
-# EOF is [false, false].
-# (TOKENSYMBOL is a Ruby symbol (taken from String#intern) by default.
-# If you want to change this, see the grammar reference.
-#
-# Racc::Parser#yyparse is little complicated, but useful.
-# It does not use Racc::Parser#next_token, instead it gets tokens from any iterator.
-#
-# For example, <code>yyparse(obj, :scan)</code> causes
-# calling +obj#scan+, and you can return tokens by yielding them from +obj#scan+.
-#
-# == Debugging
-#
-# When debugging, "-v" or/and the "-g" option is helpful.
-#
-# "-v" creates verbose log file (.output).
-# "-g" creates a "Verbose Parser".
-# Verbose Parser prints the internal status when parsing.
-# But it's _not_ automatic.
-# You must use -g option and set +@yydebug+ to +true+ in order to get output.
-# -g option only creates the verbose parser.
-#
-# === Racc reported syntax error.
-#
-# Isn't there too many "end"?
-# grammar of racc file is changed in v0.10.
-#
-# Racc does not use '%' mark, while yacc uses huge number of '%' marks..
-#
-# === Racc reported "XXXX conflicts".
-#
-# Try "racc -v xxxx.y".
-# It causes producing racc's internal log file, xxxx.output.
-#
-# === Generated parsers does not work correctly
-#
-# Try "racc -g xxxx.y".
-# This command let racc generate "debugging parser".
-# Then set @yydebug=true in your parser.
-# It produces a working log of your parser.
-#
-# == Re-distributing Racc runtime
-#
-# A parser, which is created by Racc, requires the Racc runtime module;
-# racc/parser.rb.
-#
-# Ruby 1.8.x comes with Racc runtime module,
-# you need NOT distribute Racc runtime files.
-#
-# If you want to include the Racc runtime module with your parser.
-# This can be done by using '-E' option:
-#
-#   $ racc -E -omyparser.rb myparser.y
-#
-# This command creates myparser.rb which `includes' Racc runtime.
-# Only you must do is to distribute your parser file (myparser.rb).
-#
-# Note: parser.rb is ruby license, but your parser is not.
-# Your own parser is completely yours.

-The exec command handles installing (if necessary) and running an executable

-
-The exec command can be thought of as a shortcut to running `gem install` and
-then the executable from the installed gem.
-
-For example, `gem exec rails new .` will run `rails new .` in the current
-directory, without having to manually run `gem install rails`.
-Additionally, the exec command ensures the most recent version of the gem
-is used (unless run with `--conservative`), and that the gem is not installed

-# The WebauthnListener class retrieves an OTP after a user successfully WebAuthns with the Gem host.
-# An instance opens a socket using the TCPServer instance given and listens for a request from the Gem host.
-# The request should be a GET request to the root path and contains the OTP code in the form
-# of a query parameter `code`. The listener will return the code which will be used as the OTP for
-# API requests.
-#
-# Types of responses sent by the listener after receiving a request:
-#   - 200 OK: OTP code was successfully retrieved
-#   - 204 No Content: If the request was an OPTIONS request
-#   - 400 Bad Request: If the request did not contain a query parameter `code`
-#   - 404 Not Found: The request was not to the root path
-#   - 405 Method Not Allowed: OTP code was not retrieved because the request was not a GET/OPTIONS request
-#
-# Example usage:
-#
-#   thread = Gem::WebauthnListener.listener_thread("https://rubygems.example", server)
-#   thread.join
-#   otp = thread[:otp]
-#   error = thread[:error]

+#
+# === New to \Gem::OptionParser?
+#
+# See the {Tutorial}[optparse/tutorial.rdoc].
+#
+# === Introduction
+#
+# Gem::OptionParser is a class for command-line option analysis.  It is much more
+# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
+# solution.
+#
+# === Features
+#
+# 1. The argument specification and the code to handle it are written in the
+#    same place.
+# 2. It can output an option summary; you don't need to maintain this string
+#    separately.
+# 3. Optional and mandatory arguments are specified very gracefully.
+# 4. Arguments can be automatically converted to a specified class.
+# 5. Arguments can be restricted to a certain set.
+#
+# All of these features are demonstrated in the examples below.  See
+# #make_switch for full documentation.
+#
+# === Minimal example
+#
+#   require 'rubygems/optparse/lib/optparse'
+#
+#   options = {}
+#   Gem::OptionParser.new do |parser|
+#     parser.banner = "Usage: example.rb [options]"
+#
+#     parser.on("-v", "--[no-]verbose", "Run verbosely") do |v|
+#       options[:verbose] = v
+#     end
+#   end.parse!
+#
+#   p options
+#   p ARGV
+#
+# === Generating Help
+#
+# Gem::OptionParser can be used to automatically generate help for the commands you
+# write:
+#
+#   require 'rubygems/optparse/lib/optparse'
+#
+#   Options = Struct.new(:name)
+#
+#   class Parser
+#     def self.parse(options)
+#       args = Options.new("world")
+#
+#       opt_parser = Gem::OptionParser.new do |parser|
+#         parser.banner = "Usage: example.rb [options]"
+#
+#         parser.on("-nNAME", "--name=NAME", "Name to say hello to") do |n|
+#           args.name = n
+#         end
+#
+#         parser.on("-h", "--help", "Prints this help") do
+#           puts parser
+#           exit
+#         end
+#       end
+#
+#       opt_parser.parse!(options)
+#       return args
+#     end
+#   end
+#   options = Parser.parse %w[--help]
+#
+#   #=>
+#      # Usage: example.rb [options]
+#      #     -n, --name=NAME                  Name to say hello to
+#      #     -h, --help                       Prints this help
+#
+# === Required Arguments
+#
+# For options that require an argument, option specification strings may include an
+# option name in all caps. If an option is used without the required argument,
+# an exception will be raised.
+#
+#   require 'rubygems/optparse/lib/optparse'
+#
+#   options = {}
+#   Gem::OptionParser.new do |parser|
+#     parser.on("-r", "--require LIBRARY",
+#               "Require the LIBRARY before executing your script") do |lib|
+#       puts "You required #{lib}!"
+#     end
+#   end.parse!
+#
+# Used:
+#
+#   $ ruby optparse-test.rb -r
+#   optparse-test.rb:9:in `<main>': missing argument: -r (Gem::OptionParser::MissingArgument)
+#   $ ruby optparse-test.rb -r my-library
+#   You required my-library!
+#
+# === Type Coercion
+#
+# Gem::OptionParser supports the ability to coerce command line arguments
+# into objects for us.
+#
+# Gem::OptionParser comes with a few ready-to-use kinds of  type
+# coercion. They are:
+#
+# - Date  -- Anything accepted by +Date.parse+
+# - DateTime -- Anything accepted by +DateTime.parse+
+# - Time -- Anything accepted by +Time.httpdate+ or +Time.parse+
+# - URI  -- Anything accepted by +URI.parse+
+# - Shellwords -- Anything accepted by +Shellwords.shellwords+
+# - String -- Any non-empty string
+# - Integer -- Any integer. Will convert octal. (e.g. 124, -3, 040)
+# - Float -- Any float. (e.g. 10, 3.14, -100E+13)
+# - Numeric -- Any integer, float, or rational (1, 3.4, 1/3)
+# - DecimalInteger -- Like +Integer+, but no octal format.
+# - OctalInteger -- Like +Integer+, but no decimal format.
+# - DecimalNumeric -- Decimal integer or float.
+# - TrueClass --  Accepts '+, yes, true, -, no, false' and
+#   defaults as +true+
+# - FalseClass -- Same as +TrueClass+, but defaults to +false+
+# - Array -- Strings separated by ',' (e.g. 1,2,3)
+# - Regexp -- Regular expressions. Also includes options.
+#
+# We can also add our own coercions, which we will cover below.
+#
+# ==== Using Built-in Conversions
+#
+# As an example, the built-in +Time+ conversion is used. The other built-in
+# conversions behave in the same way.
+# Gem::OptionParser will attempt to parse the argument
+# as a +Time+. If it succeeds, that time will be passed to the
+# handler block. Otherwise, an exception will be raised.
+#
+#   require 'rubygems/optparse/lib/optparse'
+#   require 'rubygems/optparse/lib/optparse/time'
+#   Gem::OptionParser.new do |parser|
+#     parser.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
+#       p time
+#     end
+#   end.parse!
+#
+# Used:
+#
+#   $ ruby optparse-test.rb  -t nonsense
+#   ... invalid argument: -t nonsense (Gem::OptionParser::InvalidArgument)
+#   $ ruby optparse-test.rb  -t 10-11-12
+#   2010-11-12 00:00:00 -0500
+#   $ ruby optparse-test.rb  -t 9:30
+#   2014-08-13 09:30:00 -0400
+#
+# ==== Creating Custom Conversions
+#
+# The +accept+ method on Gem::OptionParser may be used to create converters.
+# It specifies which conversion block to call whenever a class is specified.
+# The example below uses it to fetch a +User+ object before the +on+ handler receives it.
+#
+#   require 'rubygems/optparse/lib/optparse'
+#
+#   User = Struct.new(:id, :name)
+#
+#   def find_user id
+#     not_found = ->{ raise "No User Found for id #{id}" }
+#     [ User.new(1, "Sam"),
+#       User.new(2, "Gandalf") ].find(not_found) do |u|
+#       u.id == id
+#     end
+#   end
+#
+#   op = Gem::OptionParser.new
+#   op.accept(User) do |user_id|
+#     find_user user_id.to_i
+#   end
+#
+#   op.on("--user ID", User) do |user|
+#     puts user
+#   end
+#
+#   op.parse!
+#
+# Used:
+#
+#   $ ruby optparse-test.rb --user 1
+#   #<struct User id=1, name="Sam">
+#   $ ruby optparse-test.rb --user 2
+#   #<struct User id=2, name="Gandalf">
+#   $ ruby optparse-test.rb --user 3
+#   optparse-test.rb:15:in `block in find_user': No User Found for id 3 (RuntimeError)
+#
+# === Store options to a Hash
+#
+# The +into+ option of +order+, +parse+ and so on methods stores command line options into a Hash.
+#
+#   require 'rubygems/optparse/lib/optparse'
+#
+#   options = {}
+#   Gem::OptionParser.new do |parser|
+#     parser.on('-a')
+#     parser.on('-b NUM', Integer)
+#     parser.on('-v', '--verbose')
+#   end.parse!(into: options)
+#
+#   p options
+#
+# Used:
+#
+#   $ ruby optparse-test.rb -a
+#   {:a=>true}
+#   $ ruby optparse-test.rb -a -v
+#   {:a=>true, :verbose=>true}
+#   $ ruby optparse-test.rb -a -b 100
+#   {:a=>true, :b=>100}
+#
+# === Complete example
+#
+# The following example is a complete Ruby program.  You can run it and see the
+# effect of specifying various options.  This is probably the best way to learn
+# the features of +optparse+.
