Template:P1/doc

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 baz
• {{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":

• {{[[Template:P{{{1}}}|P{{{1}}}]]|<output if 1>|<output if 2>|<output if 3>}}

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

• {{[[Template:#switch:{{{1}}}|#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.
