What tools are you using to develop Lua games and apps?

[Evil Inside]

I know there are Lua Player versions being developed for PC and Mac by some of the fine developers here, but what are you developers using right now to develop Lua games and apps?

I've played around with the Lua Player PC preview that Shine released, but I'd like to continue developing on my Mac at home.

Are there some opensource development tools I can use to test scripts on Mac OSx?

Thanks.
