 | This template is used on 842,000+ pages, or roughly 5% of all pages.

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 the {{category other}} meta-template.
This template helps other templates detect if they are on a "Category:" page or some "other" type of page.
Usage
This template usually takes two parameters, like this:
<syntaxhighlight lang="wikitext"> Other pages text </syntaxhighlight>
If the template is on a "Category:" page, it will return this:
- Category page text
If the template is on any other page, it will return this:
- Other pages text
A typical usage case could be to make it so that a template only adds a category when on category pages. Thus not adding other pages that just show the template. Like this:
<syntaxhighlight lang="wikitext">
</syntaxhighlight>
Or to warn that a template should not be used on other pages:
<syntaxhighlight lang="wikitext"> This template should only be used on category pages. </syntaxhighlight>
Note that in the first case above the "other" parameter was not used, and in the second example the "category" parameter was left empty.
Demospace
For testing and demonstration purposes this template can take a parameter named demospace.
- If it has the value category it returns the category page text.
- It if has the value other or any other value such as the name of some other namespace it returns the other pages text.
- If the parameter is empty or undefined, the actual page type determines the result.
Like this:
<syntaxhighlight lang="wikitext"> Category page text </syntaxhighlight>
No matter on what kind of page the code above is used it will return this:
- Category 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"> Other pages text </syntaxhighlight>
Technical details
