Programming in Lua

Lua is a general purpose scripting language. It is embeddable in a C-program, and can be extended to call functions written in C. It is lean and mean, while being a full fledged and elegant language. It has a small memory footprint.

Lua is a good language to run on the desktop, but is great to have on smaller devices. I have it running on:

• The remote control of my Logitech Sqeezebox Duet music system
• My Iliad E-book reader
• My Canon digital camera (CHDK)

• Alien (call functions in shared libs)
• Tolua++ (call C++ code from Lua)
• Lunit (Unit testing)

• Programming in Lua (5.0) (very good an readable), buy the 5.1 PiL if you can
• Reference manual for Lua 5.1
• http://www.lua.org/about.html

I have written a few scripts…

• XL: A simple XML parser
• print_r: pretty-print Lua tables (for debugging)
• Convert numeric html entities to utf8
