Template:Xpd

Template:Hh This template Template:Tim shows the call of a template or predefined template and its result, for documentation.|

Usage:

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

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

The default separator is "gives", use s== or similar to get "=" etc. Please note that for colon functions the first parameter belongs to the left side before the "|" vertical bar aka pipe.

Examples without additional parameters:

Examples:

1. {{Xpd|CURRENTDAY|s=is}} displays

   {{ CURRENTDAY}} is "18"

2. {{Xpd|#expr:2*3}} displays

   {{ #expr:2*3}} gives "6"

3. {{Xpd|1=#expr:2+2=5}} displays

   {{ #expr:2+2=5}} gives "0"

4. {{Xpd|1=#expr:(2+2=4)|s==}} displays

   {{ #expr:(2+2=4)}} = "1"

5. {{Xpd|urlencode:!|s==}} displays

   {{ urlencode:!}} = "%21"

6. {{Xpd|uc:abc} gives

   {{ uc:abc}} gives "ABC"

7. {{subst:Xpd|uc:Upper Case|subst=subst:}} substitutes

   {{ subst:uc:Upper Case}} gives UPPER CASE

   See Help:Substitution for several caveats wrt subst=subst:.

As always the expression (first parameter) cannot directly contain "|", "=", plus other special cases related to square brackets / curly braces. In the case of this template "not directly" means "never" except from "=" as shown above.

This template and Template:Lts can be used if the case of an expression in double braces which itself includes a pair of double braces (simple nested expressions). For the former, use named parameters 1n (Nested part of first parameter) and optionally 1a (part After that). For the latter, use "|" for the inner "{{" and, if there is code after it, also for "}}".

1. {{evd|#expr:24*|1n=CURRENTDAY}} gives Template:Evd
2. {{evdn|#expr:24*|CURRENTDAY}} gives Template:Evdn
3. {{evd|#expr:24*|1n=CURRENTDAY|1a=-24}} gives Template:Evd
4. {{evdn|#expr:24*|CURRENTDAY|-24}} gives Template:Evdn
5. {{evdn|#expr:4*|#expr:not 0| >3 | yields}} displays

   Template:Evdn

6. {{evdn|urlencode:|DIRMARK}} displays

   Template:Evdn

Examples with additional parameters (no nesting possible):

Example:

{{Xpd|#ifeq: 1.00|+1|okay}} gives:

{{ #ifeq: 1.00|+1|okay}} gives "okay"

Example:

{{Xpd|#ifeq: this|that||false|is}} gives:

{{ #ifeq: this|that||false}} gives "false"

Example:

{{Xpd|#expr: 3*4}} gives:

{{ #expr: 3*4}} gives "12"

Example:

{{evaldemo|#expr: 3*4}} gives:

Template:Evaldemo

{{ tc}} gives "{{tlc|...}}"

{{ t|b}} gives "{{b}}"

{{ t|b|c}} yields "{{b}}"

{{ t2|b|c}} gives "Template:T2"

{{ t2|b|c|d}} gives "Template:T2"

{{ t2|b|c|d}} yields "Template:T2"

Optional substitution with subst=subst: is not supported. It's anyway against the spirit of this demo template showing what another template actually does, and not what it did some time ago.
