This is an old revision of the document!
Here it is, however incomplete or limited. I will make sure I note how complete docs are for each, so you'll know going in what to expect. Most of these are hosted on GitHub, under my username: Muragami. Links into the main doc page for each below:
Docs: Maxrects-lua
An implementation of the MAXRECTS 2d rectangle packing algorithm in Lua, somewhat optimized for LuaJIT. It is pretty flexible, as it just packs rectangles. You can attach a field in the rectangle called data, and that can hold your information about the specific rectangle (for instance, image information).
Docs: Rogue-lua (Coming soon)
