邓建平任上海市绿化和市容管理局局长 陆月星不再担任
This is a meta-template which helps other templates detect whether they are used in the "Template:" namespace.
Usage
[edit bunsu]This template usually takes one or two parameters:
For example, if Templat:Tlf 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 Templat:Tlf 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
[edit bunsu]The parameter demospace 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:
{{Template other
| demospace = template
| Template page text
| Other pages text
}}
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:
{{template other
| Template page text
| Other pages text
| demospace = {{{demospace|}}}
}}
Technical details
[edit bunsu]This template detects "Template talk:" pages as type other. For more details relevant to this template, see {{Main talk other}}, which works similarly.
