This morning I attended another JRuby talk, this time with Thomas Enebo. It turned out to be, almost default, Sun JRuby talk.
There was one interesting difference, though. Normally we are shown how to run Ruby on Java and how to use Java components in our Ruby apps. Thomas took JMonkeyEngine (a java 3d scenegraph/game engine) and showed that he coded a simple game in Ruby, steering clear of the rather complex Java code.
This is, of course, another great feature of JRuby, you can code a “Java” app, and in certain places actually use Ruby to write cleaner or “easier” code.
Well worth the time!
