Overview

Public: Various methods useful for performing ISO-639 language code lookup either given their ISO-639-1 or ISO-639-2 character code value or from human input.

Language code mappings came from loc.gov/standards/iso639-2/ISO-639-2_utf-8.txt

Examples

Iso639["en"]                          # => "English"
Iso639["en"].alpha2                   # => "en"
Iso639["en"].alpha3                   # => "eng"
Iso639["en"].alpha3_bibliographic     # => "eng"
Iso639["en"].alpha3_terminology       # => "eng"
Iso639["en"].name                     # => "English"
Iso639["en"].english_name             # => "English"
Iso639["en"].french_name              # => "anglais"

Iso639["German"]                      # => "German"
Iso639["German"].alpha2               # => "de"
Iso639["German"].alpha3               # => "ger"
Iso639["German"].alpha3_bibliographic # => "ger"
