Symfony2从javascript提取文本到翻译

Question

I have installed BazingaJsTranslationBundle in my Symfony2 project.

It works fine but is there a way to extract text from javascript file the way done in translation:extract symfony2 command?

The text in javascript file looks like this:

Translator.trans("This is the text that I want to extract")

I do not want to go through adding keys in twig or php files to translate text in javascript files.

Here is the command that I use to extract text from php and twig files:

php app/console translation:extract en
--enable-extractor=jms_i18n_routing --dir=./src/ --output-dir=./app/Resources/translations

You can by creating a custom extractor for the JS translations. That's done by implementing the Symfony\\Component\\Translation\\Extractor\\ExtractorInterface :

/**
 * Extracts translation messages from a template directory to the catalogue.
 * New found messages are injected to the catalogue using the prefix.
 *
 * @author Michel Salib <michelsalib@hotmail.com>
 */
interface ExtractorInterface
{
    /**
     * Extracts translation messages from a template directory to the catalogue.
     *
     * @param string           $directory The path to look into
     * @param MessageCatalogue $catalogue The catalogue
     */
    public function extract($directory, MessageCatalogue $catalogue);

    /**
     * Sets the prefix that should be used for new found messages.
     *
     * @param string $prefix The prefix
     */
    public function setPrefix($prefix);
}

To make it usefull to others, it'll be even more awesome if you submitted your extractor to the BazingaJsTranslationBundles.
