The Canon Hack Development Kit (CHDK), an open source firmware for Canon cameras, uses Lua as one of two scripting languages. Celestia, the astronomy educational program, uses Lua as its scripting language. Cheat Engine, a memory editor/debugger, enables Lua scripts to be embedded in its "cheat table" files, and even includes a GUI designer.
Lua scripts may load extension modules using require, [20] just like modules written in Lua itself, or with package.loadlib. [22] When a C library is loaded via require ( 'foo' ) Lua will look for the function luaopen_foo and call it, which acts as any C function callable from Lua and generally returns a table filled with methods.

The script at Module:LuaCall has been written to accept any set of named parameters somename=value, for each one storing the string value in the variable with the name somename, and then allowing you to use these variables as parameters for any function available in Lua. The script then returns only the first value returned by the function (Lua ...
A sample of Lua is highlighted by tag <syntaxhighlight lang="lua">...</syntaxhighlight> placed around the Lua source code. To view some more complex examples of Lua, see article: "Lua (programming language)". For instructions on how to use Lua within MediaWiki (and hence Wikipedia), see mw:Extension:Scribunto/Lua reference manual.
Scribunto Lua reference manual; Programming in Lua; Introduction to Lua patterns; About regex. Lua "patterns" are based on Regex (Patterns are a reduced set of regex). Help:Lua metamodules: Lua in Wikipedia has several meta-modules available that can make core functions easily available.
The language in which modules are written is Lua. Unlike the template parser function system, Lua was actually designed not only to be a proper programming language, but also to be a programming language that is suitable for what is known as embedded scripting. Modules in MediaWiki are an example of embedded scripts.
The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. For example, a search of a 40,000-character article text, for 99 separate words (passed as 99 parameters in a template), ran within one second of Lua CPU clock time.
