Re: Hacking BeanShell with JavaCC

Hi Folks,

I posted Part II which includes implementation of Python / Groovy
style named arguments:
http://www.techhui.com/profiles/blog/show?id=1702911%3ABlogPost%3A12211

Again, I'm not proposing new features for BeanShell or trying to
create a new language.  The purpose of the post is to demonstrate how
to modify BeanShell and other languages that are defined with JJTree
grammars.  This is also a useful way to jump into JavaCC and JJTree if
you plan to eventually write an entire language from scratch.

I hope you find it useful.

Cheers,
Dan
