Would be nice if you could also recommend a LUA-IDE at the download-page, for example Smultron
(which works fine for me). (This is no advertising, it was just the first LUA-IDE i found for Mac OS X...and it's small an fast)
Hi smrx, smultron is nice, but if I can give you an advice try textmate
It's really a killer app, I use it every day, with every kind of projects and languages. I don't remember if lua ships with the basics bundles, but once you've downloaded the software, a whole repository
awaits you with a full load of bundles. It hasn't been updated since a long time (for the main thing, but you can set in the prefs for cutting-edge), and some sexy features from other editors as live search are definetly missing, but when you enter the realm of bundles, snippets and commands, you won't come back
I mainly goes freeware on X, but it's one of the few shareware I bought.
