php - 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

translation-identifier: Translated text here

Translating text looks like this from Twig

'translation-identifier'|trans({}, 'domain')

The thing is, in some cases I would like to have two different texts for same translation (not for pluralization). Here's how I would like it to work:

1. Define two texts in yml file for translations that need to have different texts. Each would have it's own unique suffix

   translation-identifier-suffix1
   
   translation-identifier-suffix2
   

2. Define a global rule that would define which suffix should be choosen. Psuedocode below:

    public function getSuffix() {
      return rand(0, 10) < 5 ? '-suffix1' : '-suffix2';
    }
   

3. Twig (and PHP) would look the same - I would still specify just the identifier without suffix. Translator would then append suffix to the identifier and try to find a match. If there would be no match it would try to find a match again without suffix.

AFAIK, Translator component doesn't support it.

But if you want same kind of behavior, you could do by overriding the translator service.

1) Override the service

# app/config/config.yml
parameters:
    translator.class:      AcmeHelloBundleTranslationTranslator

First, you can set the parameter holding the service's class name to your own class by setting it in app/config/config.yml. FYI: https://github.com/symfony/FrameworkBundle/blob/master/Resources/config/translation.xml

2) Extend the translator class provided symfony framework bundle. FYI: https://github.com/symfony/FrameworkBundle/blob/master/Translation/Translator.php

3) Overwrite the trans function which is provider by translator component. https://github.com/symfony/Translation/blob/master/Translator.php

Hope this helps!
