Parser Functions and Lua Scripts

Parser and Lua⌘

• General MediaWiki does not allow for logic to be implemented

• Parser functions were introduced to give MediaWiki some programming like functionality

allowing you to use commands like if and exists.

• You can define your own parser functions, and there is an extension with predefined functions that comes bundled with MediaWiki since version 1.17.

• Unfortunately these are somewhat limited, and complex logic can become unreadable.

• The scribunto extension is being developed, to allow use of programming languages in MediaWiki, currently only supporting the Lua Scripting language.

Lua scripts are created in the Module namespace, Module:MyScript

to invoke a script

{{#invoke: MyScript | function | parameter1 | paremeter2 }}
