Template:P2/doc

Note: This template is used on a lot of pages. In order not to put too much load on the servers, edits should be kept to a bare minimum.
Please discuss proposed changes on the talk page first.
Editing a template causes all pages that use the template to be re-rendered. If the Template is used often, this can put a lot of load on the servers since it fills up the job queue. [statistics]

The templates P1 and P2 simply return the first respectively second unnamed input parameter respectively. For example:

• {{P1|foo|bar|baz}} returns foo
• {{P2|foo|bar|baz}} returns bar

These templates can be used inside other templates as an alternative to the {{#switch}} parser function, to switch between outputs based on whether the input is "1" or "2":

• {{P{{{1}}}|output if 1|output if 2}}

Using {{#switch}}, this syntax is equivalent to

• {{#switch:{{{1}}}|1=output if 1|2=output if 2}}

except that the parser function strips whitespace between parameters whereas the templates don't.
