Template:Template other
 | This template is used on 4,240,000+ pages, or roughly 61113% of all 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 is a meta-template which helps other templates detect whether they are used in the "Template:" namespace.
Usage
This template usually takes one or two parameters:
{{Template other |[result/action if on a template page] (|[result/action if on another type of page])}}
For example, if {{Template other |On template page |Not on template page}} were on a "Template:" page, it would return:
- On template page
On any other type of page (e.g. "Wikipedia:", "User:") it would return:
- Not on template page
A typical use is to manage the categorization of template pages. Adding {{Template other | |Template:!((Category:[category name]Template:))!}} to a template, for instance, means it would only categorize a page when that page isn't a template page. (The first parameter consists of nothing, so no action taken if/when the template is on a template page.)
Demospace
The parameter Template:Ifsubstdemospace can be used to demonstrate or test this template. By default, it is undefined and has no effect on the template's action, but:
- when set as "template" (
|demospace=template), it prompts the template to return the first result/action above (i.e. to behave as if on a "Template:" page) even if the template is on a different type of page; - when set as "other" (
|demospace=other), it prompts the template to return the second result/action above (i.e. to behave as if not on a "Template:" page) even if the template is on a "Template:" page.
For example: <syntaxhighlight lang="wikitext"> Template page text </syntaxhighlight> No matter on what kind of page the code above is used, it returns: Template page text
You can make it so your template also understands the demospace parameter. That means you can demonstrate the different appearances of your template in the documentation for your template. Then do like this:
<syntaxhighlight lang="wikitext"> Template page text </syntaxhighlight>
Technical details
This template detects "Template talk:" pages as type other. For more details relevant to this template, see {{Main talk other}}, which works similarly.
