Adding new languages

Translations for this site are managed in the Open Technology Fund's Localization Lab Transifex site. Contributing translators may choose to translate and/or review translations there. Completed translations are then imported for use within this application and published by M-Lab staff.

How to add a new localization

• Download a completed language translation file
  • Visit the Transifex site and locate a completed language
  • Click Interface Language Strings and then Download for use to download the completed language .po file
  • Save it in the folder: /translations/source/ using the file name pattern: .po
• Create new language template & update language string references
  • Create a copy of an existing translation folder and index.html file, and make some edits to support the new language
    • Copy the folder and index file: cp -r app/nl app/es
    • Edit the index file to change the language it references. In app/es/index.html:
      • change: const INTERFACE_LANGUAGE = 'nl'; to const INTERFACE_LANGUAGE = 'es';
      • change: <script src="/assets/translations/it.js"></script>
    • to: <script src="/assets/translations/es.js"></script>
  • Regenerate the supported language strings:
    • gulp inject
