JRuby iconJRuby 1.7.15

Java powered Ruby implementation
JRuby is a 100% Java implementation of the Ruby programming language. It is Ruby for the JVM. JRuby is an alternate implementation of the Ruby programming language. It is also an embedded language for the Java Virtual machine (JVM).

JRuby provides a complete set of core "builtin" classes and syntax for the Ruby language, as well as most of the Ruby Standard Libraries.

The standard libraries are mostly Ruby's own complement of .rb files, but a few of them that depend on C language-based extensions have been reimplemented. Some are still missing, but we hope to implement as many as is feasible.|

Main features:

  • The Best of the JVM:
  • High performance
  • Real threading
  • Vast array of libraries
  • It's Just Ruby:
  • Ruby 1.8.7 & 1.9.2 compatible
  • Both versions in single install
  • Platform Independent:
  • Easy to install
  • Easy migration
  • No hassles
