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

Usage:

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

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

Examples without additional parameters:

{{ xpd | tc }}	{{tc}} gives Template:Tc
{{ 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 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 Template:T
{{ xpd | t2 | b | c }}	{{t2|b|c}} gives Template:T2

In the case of one or more named parameters, write all parameter definitions from that as value of the appropriate parameter number, e.g.:

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

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

Separator parameter

Usage:

{{ xpd | left side | up to 3 additional parameters | s=separator }}

{{ xpdn | left side | nested part and optional last part | s=separator }}

The default separator is "gives", use s== or similar to get "=" etc.

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
