Template:Demo

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

{{demo|<nowiki>{{your template}}</nowiki>}}

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

<big style="color:#DF0A24; font-size:1.4em;">&#x2717;</big>&nbsp;'''Fail'''
 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}}
 Done

Separator

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

{{demo|sep=produces|<nowiki>{{done}}</nowiki>}}
{{done}}
produces  Done

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

{{done}}
 Done

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 A1
 
 
Team B2
 

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)
