Template:If in page/doc

This template searches the current page for a provided Lua mw.ustring pattern. If you need help with these, you could ask Wikipedia talk:Lua, Wikipedia:Village pump (technical), or a 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 | pipe character use {{!}}.

Usage

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

Examples

• {{If in page |%{%{[Uu]se British English%}%}|colour|color}} would output colour if a page contains {{Use British English}} or color if it does not
