Help:Lua

Lua is a programming language that is designed to be fast, portable, extensible, and easy to learn. Lua can be used on templates on thanks to the Scribunto extension.

Lua code is stored in the Module namespace, and is called through the use of the  parser function.

The Scribunto extension provides a few core libraries for Lua use on MediaWiki-based sites. You can find a list of them in the Lua reference manual.
