Template:Single namespace
 | This template is used on approximately 230,000 pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This template should not be substituted. |
Usage
[edit]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
[edit]Correct namespace
[edit]{{Single namespace|Template|This text is only displayed in the Template namespace}}
This text is only displayed in the Template namespace
Incorrect namespace
[edit]{{Single namespace|Category|This text is only displayed in the Category namespace}}
 | The above template should only be transcluded in the Category namespace(s). |
