Alan Wu eb1a84a9c3 When YJIT is not built, hide options and use MJIT for --jit
YJIT is now a build-time opt-in so on platforms that YJIT could support
it could still be unavailable due to user discretion. Use MJIT for --jit
and don't display YJIT related command line options in --help when YJIT
is not included in the build.

What is Ruby?

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

Features of Ruby

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

How to get Ruby with Git

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 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:
