Module:Pn/doc: Difference between revisions

The module returns one value from its list of unnamed parameters.

The named parameter |idx= is the index of the parameter that is to be returned.

Negative indices count backward from the end of the list.

A wrapper template may be used to simplify usage.

Examples

• {{#invoke:Pn |getVal | idx=1}} →
• {{#invoke:Pn |getVal | idx= | a | b | c | d | e | f }} → a
• {{#invoke:Pn |getVal | idx=1 | a | b | c | d | e | f }} → a
• {{#invoke:Pn |getVal | idx=2 | a | b | c | d | e | f }} → b
• {{#invoke:Pn |getVal | idx=-1 | a | b | c | d | e | f }} → f
