This is a Java based implementation of the LOLCODE language.

Update

Martin Fowler plugs LOLcode

"The ruby/rails hype has also generated interest in other exotic JVM languages."

He doesn't mention LOLcode by name, but I think it falls in the 'exotic JVM languages' category.

The project has a working parser, and a partially functioning interpreter. The HAI WORLD and COUNT!!1 programs currently can be executed.

• Since LOLCODE does not have curly braces and semi colons, I've made line endings significant.
• White space is generally only required between tokens, and any number of tabs or spaces are allowed.
