This is a documentation subpage for Template:Evd.
It contains usage information, categories and other content that is not part of the original template page.
To view the template page itself, see Template:Evd.

This template Template:evd (talk, backlinks, edit) shows the call of a template or predefined template and its result, for documentation.|

Usage

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

{{evd|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 parser functions the first parameter belongs to the left side before the "|" vertical bar aka pipe.

Examples

Examples without additional parameters:

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

   {{CURRENTDAY}} is 8

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

   {{#expr:2*3}} gives 6

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

   {{#expr:2+2=5}} gives 0

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

   {{#expr:(2+2=4)}} = 1

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

   {{urlencode:!}} = %21

6. {{evd|uc:abc}} gives

   {{uc:abc}} gives ABC

7. {{subst:evd|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:Evdn (edit|talk|history|links|watch|logs) 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 {{#expr:24*{{CURRENTDAY}}}} gives 192
2. {{evdn|#expr:24*|CURRENTDAY}} gives {{ #expr:24*{{ CURRENTDAY}}}} gives 192
3. {{evd|#expr:24*|1n=CURRENTDAY|1a=-24}} gives {{#expr:24*{{CURRENTDAY}}-24}} gives 168
4. {{evdn|#expr:24*|CURRENTDAY|-24}} gives {{ #expr:24*{{ CURRENTDAY}}-24}} gives 168
5. {{evdn|#expr:4*|#expr:not 0| >3 | yields}} displays

   {{ #expr: 4*{{ #expr:not 0}} >3 }} yields 1

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

   {{ urlencode:{{ DIRMARK}}}} gives %E2%80%8E

Examples with additional parameters (no nesting possible):

Example:

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

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

Example:

{{evd|#ifeq: this|that||false|s=is}} gives:

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

Example:

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

{{#expr: 3*4}} gives 12

Example:

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

{{ #expr: 3*4}} gives 12

{{tc}} gives in

{{t|b}} gives start>b<end

{{t|b|c}} yields start>b<end

{{t2|b|c}} gives parameter 1 is ( b ) , parameter 2 is ( c )

{{t2|b|c|d}} gives parameter 1 is ( b ) , parameter 2 is ( c )

{{t2|b|c|d}} yields 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.:

{{evd|t link|2=wikt=abc|3=}} gives "{{t link|wikt=abc|}} gives wikt=abc"

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.
