Look here:
http://www.macromonkey.com/introduction.htmlYou can use just Notepad but it's much more productive to an editor with at least some minimal syntax highlighting.
I like "EditPlus" if nothing else because I've been using it so long, but there are a lot of free ones out that should
work well.
Just needs to have a Lua profile for it.
I wanted to have my own optional IDE (Integrated Developer Environment
http://en.wikipedia.org/wiki/Integrated ... nvironment) as to make MM like ACTOOL, etc.
ACTOOL allows you to edit, run and debug scripts in the same place.
Incidentally I might have kept on using ACTOOL but it's biggest problem is it's custom script language that has a lot of bugs and is not near as robust as Lua.
There are some pretty good open source editors and IDE but they would take a lot of work to make the quality product I'd want.
