Template:Single namespace/doc: Difference between revisions

Latest revision as of 07:55, 8 February 2024

This is a documentation subpage for Template:Single namespace.
It contains usage information, categories and other content that is not part of the original page.

This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template should not be substituted.

Usage

This is a meta-template; it should only be used within other templates. It is used for namespace detection as a simplification of {{Foo other|Example|{{Incorrect namespace|foo}}}}. If the template is transcluded in the Foo namespace, it will transclude "Example"; if not, it will transclude {{Incorrect namespace}}. Note that {{Incorrect namespace}} does not work in the template namespace.

The first parameter is necessary. It defines which namespace is the correct namespace for the template.

The second parameter is optional. It allows something (usually a category) to be transcluded in the correct namespace.

Examples

Correct namespace

{{Single namespace|Template|This text is only displayed in the Template namespace}}

This text is only displayed in the Template namespace

Incorrect namespace

{{Single namespace|Category|This text is only displayed in the Category namespace}}

The above template should only be transcluded in the Category namespace(s).
