A command-line interface (CLI) tool that utilizes the OpenAI API to translate locale files based on JSON format.

go install github.com/pandodao/i18n-cli@latest

export OPENAI_API_KEY=YOUR_API_KEY
i18n-cli translate \
  --dir ./locales \
  --source ./locales/en-US.json \
  --independent ./independent.json

in which,

• --dir: This flag specifies the directory where the locale files are located. The value ./locales specifies that the locales directory is located in the current working directory.
• --source: This flag specifies the source locale file to be used as a reference for translation.
• --independent: This flag specifies the independent locale file to be used as a reference for translation.

i18n-cli reads the directory containing locale files, retrieves translations from OpenAI, and then writes the translated content back to the same files.

To have i18n-cli translate the content of a JSON locale file, any existing values will be ignored.

If you want i18n-cli to translate a specific value, you can add a "!" at the beginning of the string. Alternatively, you can delete the key/value pair from the JSON file to have i18n-cli generate a new translation.
