I'm using Lua as scripting language for our current project and I'm currently scouring the web for a powerful Lua debugger, standalone or integrated. The best I've found so far is Decoda which is a quite handy debugger that can track a Lua process within a host program. But as an IDE and editor it's far below par, and it doesn't play well as a standalone either. Right now I'm switching between editing in Notepad++ and debugging in Decoda, which brings its own set of problems. What do you people use to debug your Lua script code? Are there better alternatives? Any input is appreciated.

i would also appreciate any input on this topic!!

I know this topic is very old, but you may still be interested : I've just written a lua debugger (graphical interface, can work remotely through a network connection). Not an IDE, just a debugger. You can download it here : http://www.cushy-code.com/grld
