JRuby

JRuby is an open source and pure Java implementation of the famous Ruby interpreter.

JRuby is tightly integrated with Java to allow both to embed the interpreter into any Java application and script any Java class.

Features:

• A 1.8.6 compatible Ruby interpreter written in 100% pure Java
• Most builtin Ruby classes provided
• Support for interacting with and defining java classes from within ruby
• Bean Scripting Framework (BSF) support
• Distributed under a tri-license (CPL/GPL/LGPL)
