Populates translations in XLIFF (.xlf) message files. Specifically developed for Angular 2 i18n - enabled apps, but might work for others as well.

Normally, you'd localize an attribute using the following syntax:
This utility makes use of the optional meaning tag to associate the message with an unique key.
The key will be persisted in the messages file as a "meaning":
Hello!A hello world message for the localized componentlocalized.component.hello
This utility will look up the keys in the supplied language file to provide the target translation.
The language files contain translations corresponding to the keys in the description.
For example, the
localized.component.hello key and its translation are represented as:
npm install -g xlf-translate
xlf-translate --lang-file sample/lang/fr.yml sample/messages.fr.xlf
This will populate all empty target elements in the
messages.xlf file with matching translations. Non-empty target elements will be skipped to avoid overwriting user translations.
The messages file will be updated in place.
You can also force overwriting all translations, regardless if empty or not:
xlf-translate --force --lang-file sample/lang/fr.yml sample/messages.fr.xlf
