controller-using-templating-http-foundation

Controller which renders a template and returns a response (HttpFoundation)

TODO

• Test more than one Symfony version!

EngineAsArgumentController

• Uses Engine as controller argument for easier configuration with Symfony 3.3
• Because Twig was not found in autoconfig as a constructor argument
• http://symfony.com/doc/current/controller.html#fetching-services-as-controller-arguments
• constructor tested only with default value

Composer configuration for use in Symfony Framework or elsewhere where this controller is called by the Symfony kernel

• as long as there is the tiniest risk that Symfony < 3.3 could be installed by composer
• ie Symfony 2.8 is supported until close to the end of 2018 it will survive up to mid 2019 and more in distributions like Debian
• https://symfony.com/roadmap

$ composer req symfony-util/controller-using-templating-http-foundation-http-kernel
