WikiIndex:Parser functions
A parser function is a special kind of magic word that is most useful for templates.
This WikiIndex:Parser functions article is a WikiIndex 'stub'. If you are familiar with, and understand the WikiIndex policy system, you can help by expanding this WikiIndex stub article, thanks. :-)
List
expr
coming soon.
if
Shows different values when entered.
- Code
{{ #if: {{{value|}}} | what to show if activated | what to show if not }}
- Example
{{ #if: {{{1|}}} | The name of this site is {{{1}}}. | This site has an unknown name. }}
Let's say this is included in the template ifExample. If {{ifExample|WikiIndex}} is entered, 'Template:IfExample' will show up because value was specified, as 'WikiIndex'. {{ifExample|not WikiIndex}} makes 'Template:IfExample', because value is specified, as 'not WikiIndex'. {{ifExample}} makes just 'Template:IfExample' because it was left blank.
ifeq

ifexist
coming soon.
ifexpr

rel2abs
coming soon.
switch
Compares values.
- Code
{{ #switch: value
| value1 = what to show if value1 is entered
| value2 = what to show if value2 is entered
| | what to show if something else is entered
| #default = what to show if nothing is entered
}}
- Example
{{ #switch: {{{1}}}
| a = argh
| b = blah
| c = cough
| | anything
| #default = nothing
}}
This is included in the template switchExample. {{switchExample|a}} gives "Template:SwitchExample" because a is entered. {{switchExample}} gives "Template:SwitchExample", because the template was left blank. {{switchExample|d}} gives "Template:SwitchExample", because d doesn't exist in the template.
time
coming soon.
