Created page with "'''Lua''' is an easy to learn but powerful scripting language. MediaWiki supports Modules written in Lua (by the extension Scribunto, bundled with 1.34+) which can simplify..."

New page

'''Lua''' is an easy to learn but powerful scripting language.

MediaWiki supports Modules written in Lua (by the extension Scribunto, bundled with 1.34+) which can simplify writing templates a lot. Especially in cases where a lot of calculations must be done efficiently or when loops are inevitable, Lua is the better choice (if not the only one).

== Notes ==
in [[mw: Extension:Scribunto#Configuration]] there are some parameters to limit the impact/load of Lua scripts may have

* memoryLimit - Specify the memory limit in bytes.
* cpuLimit - Specify the CPU time limit in seconds.
* profilerPeriod - Specify the time between polls in sections for the Lua profiler.
* allowEnvFuncs - Set true to allow use of setfenv and getfenv in modules.

There is also an article about a PHP sandbox for Lua (currently not compatible with PHP8)
