Module:Portal maintenance status

Module documentationviewedithistorypurge

This module searches a Portal_talk: page's portal page, and returns an appropriate message based if {{Portal maintenance status}} is found in the page's wikitext, and which parameters are used. An error is reported if this module is used outside of the Portal_talk namespace. It can be demonstrated, in any namespace, with the |demo= and |demo2= parameters, which take the name of templates to "find" (instead of actually searching a page).

Usage

{{#invoke:Portal maintenance status|main}}

Looks for {{Portal maintenance status}} on a Portal_talk: page's related portal page.

Returns an appropriate message string if found or an empty string if not found, or an error if used in the wrong namespace.

{{#invoke:Portal maintenance status|historical}}

Looks for {{Historical}} on a Wikipedia_talk: page's related project page.

Returns yes if found or an empty string if not found, or an error if used in the wrong namespace.

{{#invoke:Portal maintenance status|featured}}

Looks for {{Featured portal}} on a Wikipedia_talk: page's related project page.

Returns yes if found or an empty string if not found, or an error if used in the wrong namespace.
