Implemented ez_path/ez_url functions which allows to generating path/url in Twig templates from the objects of the following classes

• \eZ\Publish\API\Repository\Values\Content\Content
• \eZ\Publish\API\Repository\Values\Content\ContentInfo
• \eZ\Publish\API\Repository\Values\Content\Location
• \eZ\Publish\Core\MVC\Symfony\Routing\RouteReference

It's replacement for build-in path/url twig functions which no longer accept anything else then string as first argument:

• https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Extension/RoutingExtension.php#L46
• https://github.com/symfony/symfony/blob/master/src/Symfony/Bridge/Twig/Extension/RoutingExtension.php#L51

TODO:

• Implement feature / fix a bug.
• Implement tests.
• Fix new code according to Coding Standards ($ composer fix-cs).
• Ask for Code Review.

It would be nice if this would not throw, rather somehow allow using these methods in other packages like Netgen Tags, which also used path and url to generate links to tag objects.

That would be useful extension point, we will think of it. For now in all cases which are not supported by eZ Platform I've added fallback to replacement proposed by symfony-cmf/routing.

Thanks, I think this will be enough for now. I will test once you merge this.

It doesn't work anymore. In theory we could provide support for syntax

$this->urlGenerator->generate('', [
    RouteObjectInterface::ROUTE_OBJECT => $routeRef
])

but it will require to impl. \Symfony\Cmf\Component\Routing\ChainedRouterInterface which seems to be overkill for me.
