It is amazing to see that most of the software I like and use embed LUA, the "powerful, fast, lightweight, embeddable scripting language" :
- VLC Multimedia player can uses LUA playlist.
- Awesome Window Manager can be extended with LUA:
- SciTE source code editor can be extended with LUA.
- Rockbox firmware for mp3 players can be configured with LUA too, even if I cannot find a good official link.
- Grub 2 the boot manager has integrated lua as an alternative script engine.
