Latest commit 03271d7 Oct 18, 2016 @brixen brixen Moved builtin/ to class/.
The name 'builtin' is not very descriptive. Now that we are going to have
managed objects that are both object-oriented and simple data, and both are
'built in', we need more descriptive names for the directories, so the new
names are 'class' and 'data', which parallels the names used in the code.

Gitter Build Status

The Rubinius Language Platform

Rubinius is a modern language platform that supports a number of programming languages.

Rubinius includes a bytecode virtual machine, generational garbage collector, and just-in-time (JIT) native machine code compiler. Rubinius provides concurrency support via native OS threads with no global interpreter lock.

Rubinius runs on Mac OS X and many Unix/Linux operating systems. Microsoft Windows is not yet supported.

Code of Conduct

Participation in the Rubinius project is governed by the Rubinius Code of Conduct.

The Ruby Programming Language

Many popular Ruby applications, like Rails, run on Rubinius, which aims to be compatible with Ruby version 2.2.

Rubinius includes a Ruby parser, Ruby bytecode compiler, Ruby core library, and C-API compatibility for native C extensions. The Ruby core library is written almost entirely in Ruby. The Ruby bytecode compiler and other tools, such as the debugger, are also written in Ruby. Rubinius provides the standard Ruby libraries, with the following exceptions:

  • Continuation
  • Ripper
  • TracePoint
  • Tracer

The following Ruby features are not supported on Rubinius:

  • Refinements
  • $SAFE levels
