Template:Xpd/doc
{{#if:||}}
This Template:xpd (expansion demo) shows the call of a variable, parser function or template and its result, for documentation.
- Usage:
- {{{{#if:left side| }}xpd{{#if:left side|
| left side }}{{#if:up to 3 additional parameters| | </tt>up to 3 additional parameters }}{{#if:| | {{{4}}} }}{{#if:| | {{{5}}} }}{{#if:| | ... }}{{#if:left side| }}}}</tt>
Please note that for parser functions the first parameter belongs to the left side before "|".
Examples without additional parameters:

{{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 "}}".

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{{#if:|{{{{{1n}}}}}}}{{#ifeq:+|-||wikt=abc|||{{#ifeq:|||wikt=abc||{{#ifeq:wikt=abc|wikt=abc||wikt=abc|}}}}}}}} gives {{#ifeq:-|+|Template:T link|{{#ifeq:||Template:T link|{{#ifeq:wikt=abc|wikt=abc|Template:T link|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:
- {{{{#if:left side| }}xpd{{#if:left side|
| left side }}{{#if:up to 3 additional parameters| | </tt>up to 3 additional parameters }}{{#if:s=separator| | s=separator }}{{#if:| | {{{5}}} }}{{#if:| | ... }}{{#if:left side| }}}}</tt>
- {{{{#if:left side| }}xpdn{{#if:left side|
| left side }}{{#if:nested part and optional last part| | </tt>nested part and optional last part }}{{#if:s=separator| | s=separator }}{{#if:| | {{{5}}} }}{{#if:| | ... }}{{#if:left side| }}}}</tt>
- The default separator is "gives", use s== or similar to get "=" etc.
Examples with separator parameter:
| }}xpd{{#if:CURRENTDAY|
| CURRENTDAY
}}{{#if:s=is|
| s=is
}}{{#if:|
| {{{4}}}
}}{{#if:|
| {{{5}}}
}}{{#if:|
