Zend Framework 2 - translating routes

I am wondering if it is possible to use translational tools for routes/uris in zf2. I want for example the route

en.domain.tld/article/show/1
to translate for example to
de.domain.tld/artikel/anzeigen/1
. I don't think regex is the way to go here, because it could result in something like
en.domain.tld/artikel/show/1
. Also I want to avoid creating routes for every language, because it is going to get quite messy as the system scales.

Answer

I was able to get it working!

First, add a 'router_class' => 'Zend\Mvc\Router\Http\TranslatorAwareTreeRouteStack', your module.config.php like this:

return array (
    'router' => array (
        'router_class' => 'Zend\Mvc\Router\Http\TranslatorAwareTreeRouteStack',
        'routes' => array(),
    )
);

Second, you must provide a translator (preferably in your module.php) as well as a translation file:

class Module
{
    public function onBootstrap(MvcEvent $e)
    {
        // Load translator
       $translator = $e->getApplication()->getServiceManager()->get('translator');
       $translator->setLocale('de_DE');        

           // setup the translation file. you can use .mo files or whatever, check the translator api
           $translator->addTranslationFile('PhpArray', __DIR__.'/language/routes/de_DE.php', 'default', 'de_DE');

       $app      = $e->getTarget();

       // Route translator
       $app->getEventManager()->attach('route', array($this, 'onPreRoute'), 100);
    }

    public function onPreRoute($e){
        $app      = $e->getTarget();
        $serviceManager       = $app->getServiceManager();
        $serviceManager->get('router')->setTranslator($serviceManager->get('translator'));
    }
}

now, you should be able to use translations in your route definitions like the following:

return array (
    'router' => array (
        'routes' => array(
            'login' => array (
            'type' => 'Zend\Mvc\Router\Http\Segment',
            'may_terminate' => true,
            'options' => array (
                'route' => '/{login}',
                'defaults' => Array(
                    'controller' => '...',
                ) 
            ),
        ),
    )
);

create the translation (in this example a phpArray located in module/language/routes/de_DE.php):

<?php
return array(
    'login' => 'anmelden',
);

If I didn't forget anything, you should be good to go. I got it working in my case, so if it doesn't with the instructions above, don't hesitate to comment and I'll sort things out.
