I bumped into this very interesting scripting language while browsing the web:
http://jscheme.sourceforge.net/jscheme/main.htmlThere are some interesting thigs about this language.
The interpreter is little more than 50kb.
The language was writen by Peter Norvig one of the autors of the book "AI a modern aproach". A AI book of reference for many univs.
There is a nice way to access java called dot java:

(.add win p BorderLayout.SOUTH$)
(.addActionListener b

(.pack win)
(.show win)
(.println System.out$ "Done") |
The same code with JLIB for jScheme:

Try it here with this applet:
http://jscheme.sourceforge.net/jscheme/contrib/jswebapp/jscheme/demo/JSchemeEvaluator.htmlIt's a bit incomplete for a java user needs. It lacks run-time compilation of functions to java classes for instane. But it looks like a good scripting language. I'm think about using it with one of the opengl bindings to finnaly learn opengl.
