If it will not use special variables (like $1, $&, $`...), it can improve the performance by using Regexp#match? instead of Regexp#=~. Because Regexp#=~ will generate the objects to special variables by pattern matching. This patch will replace Regexp#=~ without special variables to Regexp#match?.

What's Ruby
Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, Haiku, etc.) cf. https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms
How to get Ruby
For a complete list of ways to install Ruby, including using third-party tools like rvm, see:
https://www.ruby-lang.org/en/downloads/
The Ruby distribution files can be found on the following FTP site:
ftp://ftp.ruby-lang.org/pub/ruby/
The trunk of the Ruby source tree can be checked out with the following command:
$ svn co https://svn.ruby-lang.org/repos/ruby/trunk/ ruby
Or if you are using git then use the following command:
$ git clone https://github.com/ruby/ruby.git
There are some other branches under development. Try the following command to see the list of branches:
$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
Or if you are using git then use the following command:
$ git ls-remote git://github.com/ruby/ruby.git

How to compile and install
This is what you need to do to compile and install Ruby:
-
If you want to use Microsoft Visual C++ to compile Ruby, read win32/README.win32 instead of this document.
-
If
./configuredoes not exist or is older thanconfigure.ac, runautoconfto (re)generate configure. -
Run
./configure, which will generateconfig.handMakefile.Some C compiler flags may be added by default depending on your environment. Specify
optflags=..andwarnflags=..as necessary to override them. -
Edit
defines.hif you need. Usually this step will not be needed. -
Remove comment mark(
#) before the module names fromext/Setup(or add module names if not present), if you want to link modules statically.If you don't want to compile non static extension modules (probably on architectures which do not allow dynamic loading), remove comment mark from the line "
#option nodynamic" inext/Setup.Usually this step will not be needed.
-
Run
make.- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
It uses the identity to sign
rubybinary. See also codesign(1).
- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
It uses the identity to sign
-
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). -
Optionally, run
make update-gemsandmake extract-gems.If you want to install bundled gems, run
make update-gemsandmake extract-gemsbefore runningmake install. -
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.

Feedback
Questions about the Ruby language can be asked on the Ruby-Talk mailing list (https://www.ruby-lang.org/en/community/mailing-lists) or on websites like (https://stackoverflow.com).
Bug reports should be filed at https://bugs.ruby-lang.org. Read HowToReport for more information.
