Template:P1/doc

This is a documentation subpage for Template:P1 (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.

The templates P1, P2 and P3 simply return the first, second and third unnamed input parameter respectively. For example:

• {{P1|foo|bar|baz}} returns foo
• {{P2|foo|bar|baz}} returns bar
• {{P3|foo|bar|baz}} returns baz

These templates can be used inside other templates as an alternative to the Template:Pf parser function, to switch between outputs based on whether the input is "1", "2" or "3":

• {{P{{{1}}}|output if 1|output if 2|output if 3}}

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

• {{#switch:{{{1}}}|1=output if 1|2=output if 2|3=output if 3}}

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