Definition: Lua

A fast, lightweight scripting language designed and maintained by the Pontifical Catholic University of Rio de Janeiro (PUC-Rio). Pronounced "loo-uh," the name means "moon" in Portuguese. It is free software but not open source, as it is written entirely by PUC-Rio. Introduced in 1993, Lua is known for its speed and small memory footprint. It is used in embedded systems as well as games on Windows, Unix/Linux and smartphone platforms and is easily integrated with programs written in other languages. Although not object oriented, it has mechanisms for creating classes and inheritance. For more information, visit www.lua.org. See object-oriented programming and programming language.
