> translate-messages

Translate en/messages.json (in chrome.i18n format) to other locales automatically.

Installation

pip install translate-messages

Usage

Run the CLI:

translate-messages [options] # or translate-msgs

If no options are passed, the CLI will:

1. Prompt for message keys to ignore
2. Auto-discover closest child _locales dir
3. Translate found en/messages.json to target languages

Note: Any messages.json in the chrome.i18n format can be used as a source file.

Options

Options can be set by using command-line arguments:

Option	Description	Example
-d, --locales-dir	Name of the folder containing locale files (default: _locales)	--locales-dir=_messages
-t, --target-langs	Comma-separated list of languages to include (default: all supported_locales)	--target-langs=en,es,fr
--exclude-langs	Comma-separated list of languages to exclude	--exclude-langs=en,es
-k, --keys	Comma-separated list of keys to translate	--keys=appDesc,err_notFound
--exclude-keys	Comma-separated list of keys to ignore	--exclude-keys=appName,author
-i, --init	Create .translate-msgs.config.jsonc in project root to store defaults
-f, --force	Force overwrite of existing config file when using --init
-W, --no-wizard	Skip interactive prompts during start-up
-h, --help	Show help screen

Examples

Translate everything except appName from _locales/en/messages.json to French and Spanish:

translate-messages --include-langs=fr,es --ignore-keys=appName -W

Translate appDesc + err_notFound keys from _msgs/en/messages.json:

translate-msgs -k appDesc,err_notFound -d _msgs -W

Config file

Use --init to create .translate-msgs.config.jsonc in your project root to set default options.

Example defaults:

{
  "locales_dir": "_locales",
  "target_langs": "",
  "keys": "",
  "exclude_langs": "",
  "exclude_keys": "",
  "force": false,
  "no_wizard": false
}

Note: CLI arguments always override config file.
