Aaron Patterson 4faaa8e5dc Collect statistics about binding allocations / local variable set 
This commit collects statistics about how many binding objects are
allocated as well as the number of local variables set on bindings.
Statistics are output along with other YJIT stats.  Here is an example
of the output:

What's Ruby

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#label-Platform+Maintainers

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/

Git

The mirror of the Ruby source tree can be checked out with 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:

$ git ls-remote https://github.com/ruby/ruby.git

You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source) if you are a committer.

Subversion

Stable branches for older Ruby versions can be checked out with also the following command:

$ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby

Try the following command to see the list of branches:

$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/

Ruby home page

https://www.ruby-lang.org/

Mailing list

There is a mailing list to discuss Ruby. To subscribe to this list, please send the following phrase:

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 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.

    Some C compiler flags may be added by default depending on your environment. Specify optflags=.. and warnflags=.. as necessary to override them.

  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.
