Template:Demo

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

Usage

This template simply places template code in a <pre>...</pre> tag and then places the template below the pre tag.

{{demo
|br =
|demo_kill_categories =
|<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|<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:

  ✗ Fail

  
  ✗ Fail

Pre style

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

For example, {{demo|style=display:inline|<nowiki>{{done}}</nowiki>}}, would result in:

{{done}}

 Done

Line breaks

You can change the number of line breaks between the pre tag and the template by setting br= to a number. The default is 1.

{{demo|br=3|<nowiki>{{done}}</nowiki>}}

{{done}}

 Done

Alternative separator

You may also include an alternative separator by setting |br= to something other than a number and it will take the place of the br tags. For example, |br=<td> can make demo fit in a table:

{{done}}

Done

Category removal

For templates that add categories (e.g. {{Asbox}}), set |demo_kill_categories= (or |nocat=) 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_br=0| 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_br= instead of |br= (all args you don't want being passed should be prefixed with 'demo_' if not already)
