Yay, I've solved the ant problem emerging some stuff related to the ant package, thanks for pointing that out :D
I'm excited about having java libs available in arc, although it would be nice to have an obvious way to disable tests on startup (now that I know it's fully functional I would like to speed the initialization up).
About the color theme: I meant the color theme used in the arc code. I bet you took those colors from an editor. Anyway, it doesn't matter at all..
Oh, the syntax highlighting, yes, welder (arc editor that comes with rainbow) can htmlify arc code so that it's easy to paste into a blog or other web page; then it's just a matter of a little CSS to decide what colour you want for different kinds of tokens.
You can just comment out the (run-all-tests) line in rainbow-libs.arc, but you're right, it should be optional somehow.
Let me know how you get on with accessing java libs, I've tried to make it as simple and concise as possible, so that your code still looks like arc code and not some outrageous contaminated half-blood hybrid monstrosity ...
