Template documentation | This template uses Lua: |
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 {{!}}.
