- Added compiler class which picks up any services tagged "twig.loader"
- If there is one loader registered we set the alias to this loader
- If there is more than one we set the alias to a chain loader and all
the loaders to it
- If there is no loaders we throw an Exception
In a template, you can now use native Twig template names, instead of
the Symfony ones:
Before (still works):
{% extends "AcmeDemoBundle::layout.html.twig" %}
{% include "AcmeDemoBundle:Foo:bar.html.twig" %}
After:
{% extends "@AcmeDemo/layout.html.twig" %}
{% include "@AcmeDemo/Foo/bar.html.twig" %}
Using native template names is also faster.
The only drawback is that the new notation looks similar to the way we
locate resources in Symfony, which would be
@AcmeDemoBundle/Resources/views/Foo/bar.html.twig. We could have used
the same notation, but it is rather verbose (and by the way, using this
notation did not work anyway in templates).
