Template:Demo

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

This template simply places template code (or any other code) in a ‎<syntaxhighlight lang="wikitext">...‎</syntaxhighlight> tag and then places the template below the code.

{{demo
|sep =
|nocat =
|<nowiki>{{your template}}</nowiki>
}}

IMPORTANT: You must wrap include ‎<nowiki>...‎</nowiki> tags around the source to be demonstrated (or use {{escape{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}}}, which has a demo-escape example), like so: {{demo|&lt;nowiki>[template source]</nowiki>}}

Failure to wrap ‎<nowiki>...‎</nowiki> tags around the source may cause the source to be executed before it reaches this template:

{{demo|{{fail}}}}

produces

[[:Template:Fail]]

Template:Fail

Pre style

Set |style= to add any CSS text to the ‎<pre>...‎</pre> tag.

For example,

{{demo|style=margin-left: 1.6em;|<nowiki>{{done}}</nowiki>}}

will produce

{{done}}

Y <translate> Done</translate>

Separator

You can change the separator between the ‎<syntaxhighlight> and the template by setting the |sep= parameter.

{{demo|sep=produces|&lt;nowiki>{{done}}</nowiki>}}

{{done}}

produces Y <translate> Done</translate>

You may use |sep=<td> can make the demonstration fit in a table:

{{done}}

Y <translate> Done</translate>

Instead of using |sep=, you can also specify the number of line breaks between the code and the template in the |br= parameter.

Reverse order

Use |reverse=1 to show the code snippet and the result in reverse order:

{{demo|reverse=1|<nowiki>{{tl|template}}</nowiki>}}

will produce

{{template}}

{{tl|template}}

Category removal

For templates that add categories (e.g. {{Asbox{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}{{---}}}}), set |nocat= (or |demo_kill_categories=) to anything to prevent them from showing up in the output:

{{Asbox
| image = Østfold_våpen.svg
| pix = 30
| subject = [[Østfold]] location
| name = Template:Østfold-geo-stub
| category = Østfold geography stubs
| tempsort = *
}}

produces:

Module

If the template used is based on Lua, you can pass args directly to the demonstrated module by invoking Module:Demo like so: (this would reduce server stress)

{{#invoke:Demo|module|demo_module=RoundN|demo_module_func=N2|demo_template=Round2
|bold_winner=high
|May 1|Team A|1|Team B|2
}}

{{Round2
|bold_winner=high
|May 1|Team A|1|Team B|2
}}

	Final
	May 1
	Team A	1
	Team B	2

Note: It will attempt to preserve line breaks for unnamed params, but such is impossible for named params since those are stripped of whitespace/order before being passed to the module. Also note, you should use |demo_sep= instead of |sep= (all args you don't want being passed should be prefixed with demo_ if not already)
