I've been playing around with Processing for a bit and love the concept of the language. That being said, I'd like to write a tool that can provide:
Syntax highlighting for user (and library) defined functions and variables.
Auto-completion
Snippets
Access to jDoc information
I'm looking at the ToolBasics page now; should I be thinking tool, library or what?
I actually came across Processing while doing research on domain specific languages. I came across a similar, but completely different, project:
Frink. Anyone here ever try it out? IMO, while interesting and even potentially useful, Frink is just not as much fun as Processing.
