{{Lua|Module:ISO 639 name}}

'''Template:Lang2iso''' takes an English-language language name (such as "Abkhazian" or "Sinhalese") and converts it into a two-letter [[ISO 639]] language code. This table's values are based on [[List of ISO 639-1 codes]]. The template should not be transcluded directly from article namespace. 

==Examples==
* {{Tlx|Lang2iso|German}} returns: {{Lang2iso|German}}
* {{Tlx|Lang2iso|Greek}} returns: {{Lang2iso|Greek}}
* {{Tlx|Lang2iso|Spanish}} returns: {{Lang2iso|Spanish}}

==Purpose==
Since most users will know a language's name but not its ISO code, this template is meant to facilitate invocations of other templates such as [[Template:Lang]]. Thus, instead of recalling (or having to know) that the ISO code for German is "de" and transcluding {{Tlx|Lang|de|Mädchen}}, one can type: {{Tlx|Lang|{{Tlx|Lang2iso|subst=y|German}}|Mädchen}}.

This also reduces the number of parameters that need to be passed to some language routines (such as those similar to [[Template:Language with name]]) since the ISO language code can now be derived from the ISO language name.
