ISO639 (ISO639 v0.1.1) View Source
This library exposes functions to convert ISO 639-1 language code representation to ISO 639-2 and backwards where it's applicable. Data for conversions was taken from https://github.com/haliaeetus/iso-639. Note about ISO 639-2/B: all Bibliographic codes will be converted to ISO 639-2 codes

Functions
expects as input downcased ISO 639-2 or ISO 639-2/B language code and returns ISO 639-1 code if it exists in standard and nil
if not. If function receives as input ISO 639-1 language code, it's returned unchanged.
expects as input downcased ISO 639-1, ISO 639-2 or ISO 639-2/B language code and returns ISO 639-2 code if it exists in standard and nil

expects as input downcased ISO 639-1, ISO 639-2 or ISO 639-2/B language code and returns ISO 639-2/B (Bibliographic) code if it exists in standard. 639-2 code is returned if bibliographic value doesn't exist. Default value is nil
for wrong argument situations.
