Advanced customization of translations in Symfony2

Question

I have a Symfony2 project and I am using Translation component for translating text. I have all translations in yml file like so

Answer 1

As of Symfony 3, Venu's answer no longer works completely, as the translator.class parameter is no longer used.

To load your custom translator class, you now need to create a compiler pass.

getDefinition('translator.default')->setClass(Translator::class);
    }
}

And this compiler pass needs to be added to the container.

addCompilerPass(new TranslatorOverridePass());
    }
}
