Template:Xpd/doc
 | This is a documentation subpage for Template:Xpd. It contains usage information, categories and other content that is not part of the original Template page. |
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}} ⇒ in
|
| {{xpd|CURRENTDAY}} | {{CURRENTDAY}} ⇒ 22
|
| {{xpd|#expr:2*3}} | {{#expr:2*3}} ⇒ 6
|
| {{xpd|1=#expr:2+2=5}} | {{#expr:2+2=5}} ⇒ 0
|
| {{xpd|1=#expr:2+2=4}} | {{#expr:2+2=4}} ⇒ 1
|
| {{xpd|urlencode:!}} | {{urlencode:!}} ⇒ %21
|
| {{xpd|uc:abc}} | {{uc:abc}} ⇒ 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}} ⇒ 504
|
| {{xpdn|#expr:4*|#expr:not 0| >3}} | {{#expr: 4*{{#expr:not 0}} >3}} ⇒ 1
|
| {{xpdn|urlencode:|DIRMARK}} | {{urlencode:{{DIRMARK}} |
Examples with additional parameters (no nesting possible):
| {{xpd|#ifeq: 1.00|+1|okay}} | +1|okay}} ⇒ okay |
{{xpd|#ifeq: this|that||false|s=is}} |
that||false}} is false |
| {{xpd|t|b}} | b}} ⇒ Tb |
| {{xpd|t2|b|c}} | b|c}} ⇒ 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.:
- {{xpd|t link|2=wikt=abc|3=}} gives "{{
t link|wikt=abc|}} ⇒ 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
[edit]- 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 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
