So I like using Notepad++ for most of the work I do. It has no native Lua autocompletion (and obviously no Corona SDK API autocompletion).
So here’s one that I spliced together using a language file I found on here, as well as a Lua language file I found elsewhere: Notepad++ Plugin: LUA + Corona API Autocompletion
Not sure if it’ll help anyone or not. Personally, I’m just getting into Corona and finding a good, free IDE has been tough
– Outlaw’s free version has an ad.
– Zerobrane’s interface was iffy for me (doing something as simple as changing the theme was irritating)
– Lua Glider costs money
Anyway…hope it assists!
