About

JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java.

The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information.

Run

bin/jruby rubyfile.rb

interprets the file rubyfile.rb.

If you checked out from the repository or downloaded the source distribution, see the next section to build JRuby first.

Compiling from source

You will need:

To compile, just type:

ant

This will create a jruby.jar file in the project lib directory. Add bin to your $PATH, and invoke jruby.

Testing

In order to run the unit tests, copy the build_lib/junit.jar file to either $ANT_HOME/lib/junit.jar or ~/.ant/lib/junit.jar.

See README.test for more information.
