How to Find Errors in Translation Files

Symfony processes all the application translation files as part of the process that compiles the application code before executing it. If there's an error in any translation file, you'll see an error message explaining the problem.

If you prefer, you can also validate the contents of any YAML translation file using the lint:yaml command:

# lint a single file
$ ./app/console lint:yaml app/Resources/translations/messages.en.yml

# lint a whole directory
$ ./app/console lint:yaml app/Resources/translations

# lint a specific bundle
$ ./app/console lint:yaml @AppBundle

The linter results can be exported to JSON using the --format option:
