Javascript version

This project is a Python version of the language-tags Javascript project.



  • Included the data folder again in the project package.
  • Added bash script ( to download the language subtag registry and move this data in the data folder of the project.


  • Allow parsing a redundant tag into subtags.
  • Added package.json file for easy update of the language subtag registry data using npm (npm install or npm update)
  • Improvement of the function: rank equal description at top. See mattcg/language-tags#4




  • Adjust language, region and script properties of Tag. The properties will return language_tags.Subtag.Subtag instead of a list of string subtags

    > print(tags.tag('nl-BE').language)
    '{"subtag": "nl", "record": {"Subtag": "nl", "Suppress-Script": "Latn", "Added": "2005-10-16", "Type": "language", "Description": ["Dutch", "Flemish"]}, "type": "language"}'
    > print(tags.tag('nl-BE').region)
    '{"subtag": "be", "record": {"Subtag": "BE", "Added": "2005-10-16", "Type": "region", "Description": ["Belgium"]}, "type": "region"}'
    > print(tags.tag('en-mt-arab').script)
    '{"subtag": "arab", "record": {"Subtag": "Arab", "Added": "2005-10-16", "Type": "script", "Description": ["Arabic"]}, "type": "script"}'


  • Added string and Unicode functions to make it easy to print Tags and Subtags.

    > print(tags.tag('nl-BE'))
    '{"tag": "nl-be"}'
  • Added functions to easily select either the language, region or script subtags strings of a Tag.

    > print(tags.tag('nl-BE').language)
