Template:Xpd/doc
This Template:xpd (expansion demo) shows the call of a variable, parser function or template and its result, for documentation.
- Usage:
{{xpd|left side|</tt>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 in
|
{{xpd|CURRENTDAY}} |
{{CURRENTDAY}} gives 22
|
{{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}} |
{{xpdn|#expr:24*|CURRENTDAY|-24}} |
{{#expr:24*{{CURRENTDAY}}-24}} gives 504
|
{{xpdn|#expr:4*|#expr:not 0| >3}} |
{{#expr: 4*{{#expr:not 0}} >3}} gives 1
|
{{xpdn|urlencode:|DIRMARK}} |
{{urlencode:{{DIRMARK}} |
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 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|</tt>up to 3 additional parameters|s=separator}}{{xpdn|left side|</tt>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 22
|
{{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
|
