Template-info.pngTemplate documentation

This Template:xpd (talk, backlinks, edit) (expansion demo) shows the call of a variable, parser function or template and its result, for documentation.


{{xpd|left side|up to 3 additional parameters}}

Please note that for parser functions the first parameter belongs to the left side before "|".


without additional parameters:

{{xpd|tc}} {{tc}} gives in
{{xpd|CURRENTDAY}} {{CURRENTDAY}} gives 5
{{xpd|#expr:2*3}} {{#expr:2*3}} gives 6
{{xpd|1=#expr:2+2=5}} {{#expr:2+2=5}} gives 0
{{xpd|1=#expr:2+2=4}} {{#expr:2+2=4}} gives 1
{{xpd|urlencode:!}} {{urlencode:!}} gives %21
{{xpd|uc:abc}} {{uc:abc}} gives ABC

{{subst:xpd|uc:Upper Case|subst=subst:}} substitutes {{ subst:uc:Upper Case}} gives UPPER CASE

See Help:Substitution for several caveats wrt subst=subst:.

Note that, as always, a parameter containing "=" has to be explicitly named by putting, in this case, "1=" in front.

Template:xpdn (talk, backlinks, edit) can be used in the case of an expression in double braces which itself includes a pair of double braces (simple nested expressions). Use "|" for the inner "{{" and, if there is code after it, also for "}}".

{{xpdn|#expr:24*|CURRENTDAY}} {{ #expr:24*{{ CURRENTDAY}}}} gives 120
{{xpdn|#expr:24*|CURRENTDAY|-24}} {{ #expr:24*{{ CURRENTDAY}}-24}} gives 96
{{xpdn|#expr:4*|#expr:not 0| >3}} {{ #expr: 4*{{ #expr:not 0}} >3}} gives 1
{{xpdn|urlencode:|DIRMARK}} {{ urlencode:{{ DIRMARK}}}} gives %E2%80%8E

Examples with additional parameters (no nesting possible):

{{xpd|#ifeq: 1.00|+1|okay}} {{#ifeq: 1.00|+1|okay}} gives okay
{{xpd|#ifeq: this|that||false|s=is}} {{#ifeq: this|that||false}} is false
{{xpd|t|b}} {{t|b}} gives start>b<end
{{xpd|t2|b|c}} {{t2|b|c}} gives parameter 1 is ( b ) , parameter 2 is ( c )

In the case of one or more named parameters, write all parameter definitions from that as value of the appropriate parameter number, e.g. to pass 'wikt=abc' as 2nd argument assign it to '2=' using:

{{xpd|t link|2=wikt=abc|3=}} gives "{{t link|wikt=abc|}} gives wikt=abc"

Optional substitution with subst=subst: is not supported. The xpd templates show what another template actually does, and not what it did some time ago.

Separator parameter[edit]

The default separator of template code and its result is "gives", use s== or similar to get "=" etc.

{{xpd|left side|up to 3 additional parameters|s=separator}}
{{xpdn|left side|nested part and optional last part|s=separator}}

Examples with separator parameter:

{{xpd|CURRENTDAY|s=is}} {{CURRENTDAY}} is 5
{{xpd|1=#expr:2+2|s==}} {{#expr:2+2}} = 4
{{xpdn|#expr:4*|#expr:not 0| >3 | yields}} {{ #expr: 4*{{ #expr:not 0}} >3 }} yields 1
