模板:Xpd

Template documentation[view] [edit] [history] [purge]

This 模板:Til (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}} ⇒ 模板:Tc
{{xpd|CURRENTDAY}}	{{CURRENTDAY}} ⇒ 6
{{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.

模板:Til 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}}	模板:Xpdn
{{xpdn|#expr:24*|CURRENTDAY|-24}}	模板:Xpdn
{{xpdn|#expr:4*|#expr:not 0| >3}}	模板:Xpdn
{{xpdn|urlencode:|DIRMARK}}	模板:Xpdn

Examples with additional parameters (no nesting possible):

{{xpd|#ifeq: 1.00|+1|okay}}	{{#ifeq: 1.00|+1|okay}} ⇒ okay
{{xpd|#ifeq: this|that||false|s=is}}	{{#ifeq: this|that||false}} is false
{{xpd|t|b}}	{{t|b}} ⇒ 模板:T
{{xpd|t2|b|c}}	{{t2|b|c}} ⇒ 模板: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|}} ⇒ 模板: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 6
{{xpd|1=#expr:2+2|s==}}	{{#expr:2+2}} = 4
{{xpdn|#expr:4*|#expr:not 0| >3 | yields}}	模板:Xpdn
