Template:Documentation - Miraheze Developers Wiki

Template documentation[view] [edit] [history] [purge]

Dependencies:

Module:Arguments
Module:Documentation
Module:Documentation/config

This is the {{Documentation}} template, used on almost every template page to contain that template's documented instructions and information. You may want to use {{Simple documentation}} instead, which uses a different style and fewer dependencies.

This template displays a green documentation box like you are seeing now and automatically loads the content from a /doc subpage. It can also load the content from other places if instructed to.

This template is intended for documenting templates and other pages that are transcluded onto other pages.

Use of this template allows templates to be protected where necessary, while allowing anyone to edit the documentation and categories.

Usage

Normally this template is used without any parameters, placed at the bottom of the template or page being documented, within a <noinclude> container:

<!--Last line of your template code--><noinclude>
{{Documentation}}
<!-- Add categories to the /doc subpage, interwikis to Wikidata, not here -->
</noinclude>

Then this template automatically loads the content from the /doc subpage of the template it is used on.

This template can also load the content from any other page. Like this:

<!--Last line of your template code--><noinclude>
{{Documentation |Template:Other page/doc}}
</noinclude>

Note that when loading the documentation from a page other than the local /doc page it becomes tricky to handle the categories.

The content can also be fed directly as text. Like this:

<!--Last line of your template code--><noinclude>
{{Documentation
 | content =
(some documentation)
}}</noinclude>

When the |content= parameter is used, the doc box normally does not show the [edit] [purge] links in the top right corner. Note that if the /doc page exists, a link to it is still shown in the link box below the doc box.

Parameter |1= and the |content= parameter can also be combined, like this:

<!--Last line of your template code--><noinclude>
{{Documentation |1=Template:Any page/doc
| content =
{{Template:Any page/doc |parameters}}
}}</noinclude>

Then the pagename fed as parameter 1 is used for the [edit] [purge] links and for the /doc link in the link box below the doc box. But the content parameter is used for the content shown in the doc box. The above code means that the content is transcluded as {{Any page/doc|parameters}}. In this example a parameter is also fed to the /doc page being loaded.

Shortcut

To automatically insert the noinclude tags, the template call and the guiding comment, use this substitution code:

{{subst:doc-code}}

Best practice

The code should be added at the bottom of the template code, with no space before <noinclude> (which would cause extra space on pages where the template is used).

Categories that apply to the template itself should be added to the bottom of the /doc subpage, inside <includeonly> tags.

If the documentation page contains <includeonly> or <noinclude> tags as part of the visible documentation text, replace the "<" with "<".

Heading

When in the Template namespace, this template shows this heading:

Template documentation

In most other namespaces, such as "Miraheze Developers Wiki:", it shows this heading:

Documentation

But when on File (image) pages it shows this heading:

Summary

The heading parameter can be used to set the heading to something else. Like this:

{{Documentation |heading=Infobox documentation}}

If the heading parameter is empty but defined, no heading is shown and no [edit] [purge] links are shown. Like this:

{{Documentation |heading=}}

The heading-style parameter can be fed optional CSS values. Without quotation marks " " but with the ending semicolons ;. For example:

heading-style=font-size:150%;color:red;

Link box

Below the big doc box is a small link box that shows some meta-data about the documentation. The link box shows different things depending on what parameters are fed to this template, and in which namespace it is used. In some cases the link box is not shown at all.

To hide the link box, add the parameter

|link box=off.

You can also insert customised text into the link box, by setting the |link box= parameter. For example:

  |link box=This documentation is automatically generated by [[w:Template:Country showdata]]

Automatic functions

If the documentation page does not exist, the [create] link includes a preload page so that clicking it will pre-fill the edit form with the basic documentation page format. Preload text is also used for the /sandbox and /testcases [create] links.

Subject namespaces vs. talk namespaces

Terminology: Subject namespaces are the opposite of talk namespaces. For instance "Template:" is the subject space of "Template talk:".

This template is usually placed in a subject namespace, within <noinclude> tags. But in some cases this template needs to be on the talk page:

In the Mediawiki namespace, since <noinclude> often does not work in system messages, and since the Mediawiki namespace needs to be kept clean for performance reasons.

When placed on talk pages, this template usually is placed near the top of the page and without <noinclude> tags.

The /doc, /sandbox and /testcases pages should normally be in the subject namespace, except in the namespaces that do not have the MediaWiki subpage feature enabled: Main, File, Mediawiki and Category. (But currently we only show the /sandbox and /testcases links from User, User talk, Template and Template talk namespaces.) There are also a whole bunch of other technical reasons why the /doc page must be stored under the talk page for those (but only those) namespaces.

This template automatically points its [create] links for the /doc, /sandbox and /testcases to the right namespace.

Technical details

The preload page for the /doc [create] link is Template:Documentation/preload. The preload pages for the /sandbox and /testcases [create] links are Template:Documentation/preload-sandbox and Template:Documentation/preload-testcases. The preload page for the /sandbox [mirror] link is Template:Documentation/mirror.
