  • Documentation subpages were developed to reduce server demands, or to protect the code version of widely used templates.
     

Format Demo, shows how non-expandable wikitext is rendered.

Contents

Usage

{{fd|''[[p]]''    '''q'''
r |rarr| 

[[s]]}}

gives: 

''[[p]]''    '''q'''
r {{#if:rarr|→}}

[[s]]{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives:

p q r {{#if:rarr|→}}

s{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}


Codes like "→" are represented in the even-positioned parameters 2-10. Each can contain a single code like "rarr" (without the "&" and the ";"). The odd-positioned parameters 1-11 are for the wikitext before, after, and in between.

Limitations and special considerations

As usual, if the parameter contains "=", even in a URL or in the definition of an attribute of an XML-element, put "1=" in front. A "|" in the wikitext is represented by {{!}}.

The template shows before "gives" the rendering of the expanded parameter in <pre> tags, and after "gives" the rendering of the parameter itself, with the following consequences.

Wrong results

For the examples, see also the edit box.

The template does not show <nowiki> tags before "gives", but shows the rendering of the wikitext with them: 

''p''{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives:

''p''{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}


The template does not show <pre> tags before "gives", but shows the rendering of the wikitext with them, i.e., it just removes them and shows the wikitext without further change: 

a
b
{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives: 

a
b
{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}


If, contrary to the instructions, the code "&amp;" is not represented in the special parameters, the template will display it as "&" both before and after "gives"; if this is followed for example by "arr;" it will wrongly show that the wikitext "&rarr;" is rendered unchanged: 

&arr;{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives:

&arr;{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}


Limitation of wikitexts

For the examples, see also the edit box.

The effect of expansion is not shown, what is shown before "gives" is already expanded: 

[[:Template:Tc]]{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives:

Template:Tc{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}


For demonstrating expansion, see Help:Expansion demo templates.

The <pre> tag does not prevent comment tags to be interpreted as such, so the template does not show the tags and the text in between, even before "gives": 

ac{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}

gives:

ac{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}{{#if:|&;}}
