View source for Module:Pn/doc

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

The named parameter {{para|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.

For accessing both named and unnamed parameters, see {{mfl|params|value_of}}.

== Examples ==

* <code><nowiki>{{#invoke:Pn |getVal | idx=1}}</nowiki></code> → {{#invoke:Pn |getVal | idx=1}}
* <code><nowiki>{{#invoke:Pn |getVal | idx= | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx= | a | b | c | d | e | f }}
* <code><nowiki>{{#invoke:Pn |getVal | idx=0 | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx=0 | a | b | c | d | e | f }}
* <code><nowiki>{{#invoke:Pn |getVal | idx=1 | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx=1 | a | b | c | d | e | f }}
* <code><nowiki>{{#invoke:Pn |getVal | idx=2 | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx=2 | a | b | c | d | e | f }}
* <code><nowiki>{{#invoke:Pn |getVal | idx=-1 | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx=-1 | a | b | c | d | e | f }}
* <code><nowiki>{{#invoke:Pn |getVal | idx=99 | a | b | c | d | e | f }}</nowiki></code> → {{#invoke:Pn |getVal | idx=99 | a | b | c | d | e | f }}

Using a wrapper template, {{tl|P-1}}:
* <code><nowiki>{{p-1 | a | b | c | d | e | f }}</nowiki></code> → {{p-1 | a | b | c | d | e | f }}
* <code><nowiki>{{wdib|ps=1|P8011|qid=Q84055514}}</nowiki></code> → {{wdib|ps=1|P8011|qid=Q84055514}}
* <code><nowiki>{{wdib|ps=1|P8011|qid=Q84055514|list=p-1}}</nowiki></code> → {{wdib|ps=1|P8011|qid=Q84055514|list=p-1}}
