{{Lua|Module:Mw lang}}
{{High-use}}

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

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

{{tnull|mw lang|&lt;{{var|language code or name}}>|&lt;{{var|target language code}}>|fn{{=}}&lt;{{var|function name}}>}}

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

==Examples==

<code><nowiki>{{mw lang|nv|en}}</nowiki></code> → {{mw lang|nv|en}}

<code><nowiki>{{mw lang| nv | sq }}</nowiki></code> → {{mw lang| nv | sq }}

<code><nowiki>{{mw lang|fn=is_code|nv|en}}</nowiki></code> → {{mw lang|fn=is_code|nv|en}}

<code><nowiki>{{mw lang|fn=is_code|xx}}</nowiki></code> →{{mw lang|fn=is_code|xx}}← (not valid, returns <code>nil</code>)

<code><nowiki>{{mw lang|fn=code_from_name|navajo|en}}</nowiki></code> → {{mw lang|fn=code_from_name|navajo|en}}

<code><nowiki>{{mw lang|fn=code_from_name| navahoisht | sq }}</nowiki></code> → {{mw lang|fn=code_from_name| navahoisht | sq }}
