A template similar to {{ISO 639 name}} that uses MediaWiki's language set.

Usage

This template accepts two positional parameters and has one named parameter.

{{mw lang|<language code or name>|<target language code>|fn=<function name>}}

|fn= – names the function to be called in Module:mw lang. Valid values are:
- name_from_code – (default) essentially the same as the {{#language:}} magic word
- is_code – returns true when <language code> is a valid MediaWiki language code
- code_from_name – inverse of name_from_code; attempts to return a language code for <language name>
- is_name – returns true when <language name> is a valid MediaWiki language name
<language code> required for name_from_code and is_code
<language name> required for code_from_name – case agnostic, must otherwise match MediaWiki language name exactly
<target language code> (optional) specifies MediaWiki language set to evaluate; defaults to local wiki language

Examples

{{mw lang|fn=code_from_name|navajo|en}} → nv

{{mw lang|fn=code_from_name| navahoisht | sq }} → nv
