{{lua|Module:If in page}}

This template searches the current page for a provided [[mw:Extension:Scribunto/Lua reference manual#Ustring patterns|Lua mw.ustring pattern]]. If you need help with these, you could ask [[Wikipedia talk:Lua]], [[Wikipedia:Village pump (technical)]], or a [[:Category:User lua|user who knows Lua]].

Note: the pattern is parsed by MediaWiki before being sent to the module, this means templates and magic words are decoded. If you want to add a <code>{{!}}</code> pipe character use <code><nowiki>{{!}}</nowiki></code>.

== Usage ==
*<code><nowiki>{{If in page |pattern |value if present |value if absent}}</nowiki></code> searches the current page for a given pattern
*<code><nowiki>{{If in page |pattern |value if present |value if absent |page=page}}</nowiki></code> can be used to search a page other than the current page
*<code><nowiki>{{If in page |pattern |value if present |value if absent |sub=yes}}</nowiki></code> if the pattern matches, substitutes <code>%1</code>, <code>%2</code>, <code>%3</code>, etc. in <code>value if present</code> with first, second, third, etc. capture groups. Does not work with <code>%0</code>.

== Examples ==
*<code><nowiki>{{If in page |%{%{[Uu]se British English%}%}|colour|color}}</nowiki></code> would output colour if a page contains {{tl|Use British English}} or color if it does not
