JRuby 0.9.2 was the first release to include a graphical IRB-based console. There are a number of ways to run it:
- Build the console jar yourself from source
- ant jar-console
- java -jar lib/jruby-console.jar
- Download the prebuilt console jar and run with java -jar
- Download the OS X application "SuperConsole 0.1" (based on JRuby) and install it however you wish
- Run the webstart version
