Template:Markup/doc

This is a documentation subpage for Template:Markup.
It contains usage information, categories and other content that is not part of the original template page.

This template is used to present markup or code side by side with the output it renders.

Usage

Each pair of {{Markup}}'s arguments should be two copies of some wikitext markup, with the first of the pair enclosed in Template:Xtag tags. The template produces output in two columns, the first showing the markup and the second showing how it is rendered. The template accepts up to 40 unnamed parameters, resulting in up to 20 rows of examples.

This:

{{markup|<nowiki>'''Bold text'''</nowiki>|'''Bold text'''}}

Produces this:

In many cases, the markup for both columns are identical, but there are instances where this may need to differ. If none of these issues apply, then you may use {{mra}} to save yourself from copying the code twice.

Header markup such as == will show in the page table of contents; to avoid this, use {{fake heading}} in the markup for the second column (see example below).
Some templates will place the page in a maintenance category, which is usually undesired. For example.
- Instead of {{citation needed}}, use {{fake citation needed}} in the second column.
Some templates may have error checking that places the page in a maintenance category.
- ~~Template:Cs1 templates with errors: add |template doc demo=true to the template in the second column.~~
- To avoid this and the associated red error messages make sure that each example on the page uses different sources.
HTML entities are parsed in the first cell, even with Template:Xtag tags. To work around this, replace the & with & in the first column (see example below).

It is advisable to begin both copies of the markup with a newline; this is necessary if the first line of the markup must start on a new line (such as #, * or ;).

A complex example

In this example, {{Markup}}'s second argument here uses {{fake heading}} (to avoid headings appearing in the table of contents) and {{fake citation needed}} (to avoid adding this page to the maintenance list).

With HTML entities

HTML entities are parsed in the markup cell. To work around this, replace the & with & in the first column.

Typing aid: template {{mra}}

{{mra}} will duplicate the source text automatically, saving you the trouble of copying the text and adding Template:Xtag tags to the first case.

This:

{{subst:mra|'''Bold text'''|''Italic text''}}

Will produce this:

{{markup|
<nowiki>'''Bold text'''</nowiki>|'''Bold text'''|
<nowiki>''Italic text''</nowiki>|''Italic text''}}

Which renders as:
