The English Wikipedia has several templates and Lua modules which can format or manipulate strings.In this context a "string" is any piece of text forming part of a page. This help page covers a few useful techniques; look in the navbox below for the full catalogue of templa
The Category:Lua-based templates is an index of templates which #invoke modules written in Lua script, using the Scribunto interface. The pages listed in this category are templates . This page is part of Wikipedia's administration and not part of the encyclopedia.
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Templates based on the String Lua module]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Templates based on the String Lua module]]</noinclude>

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.
This template is used to indicate that a template uses one or more Lua modules (pages in the Module: namespace). It is placed at the top of the template's /doc page. It automatically adds a floating right notification box, and it adds the template to Category:Lua-based templates or to one of its subcategories.
Also, all Lua in the page is limited to 10 seconds CPU time (you can look in the source code of a rendered page to see how long a template or module took to parse). And relative to standard Lua, Scribunto's Lua lacks all sorts of functions (see mw:Extension:Scribunto/Lua reference manual § Differences from standard Lua ).
