Translation Configuration 

Debug Translator 

Debug translator enables you to check and debug translations in the UI. To enable it, set option debug_translator to true in the config.yml file:

oro_translation:
    debug_translator: true

Additionally, refresh the backend and browser cache. All translated strings will then be wrapped into brackets, and untranslated strings will be wrapped into exclamation marks with dashes. Frontend translations have suffix “JS” to distinguish them from backend translations.

[Contact] - translated backend string
!!!---Account---!!! - not translated backend string

[Reset]JS - translated frontend string
!!!---Refresh---!!!JS - not translated frontend string

Debug JS Translations 

Debugging JS translations allows to turn off on fly JS translations generation, it can slightly boost performance on slow hardware configurations and make the application more stable on Windows. If kernel.debug is set to false, the value of debugging JS translations is ignored. To turn off JS translations generation, set option js_translation.debug to false in the config.yml file:

oro_translation:
    js_translation:
        debug: false

If you turned off JS translations generation, do it manually by executing the command below, which dumps translations for use in JavaScript:

php bin/console oro:translation:dump

The --locale option can be used to dump translations only for the specified locales:

php bin/console oro:translation:dump --locale=<locale1> --locale=<locale2> --locale=<localeN>
