  • bash script:

      source ~/IBM_TRANSLATOR_API_CREDENTIALS.sh
    
      translate-webextension-strings -i 'en' -f '/path/to/_locales/en/messages.json' -d '/path/to/_locales' -m

  • produces output files:

      /path/to/_locales/ar/messages.json
      /path/to/_locales/eu/messages.json
      /path/to/_locales/bn/messages.json
      /path/to/_locales/bs/messages.json

      translate-webextension-strings -i 'en' -o 'de' -o 'es' -o 'fr' -f '/path/to/input/file.json' -d '/path/to/output'

  • produces output files:
