Gonzalo Ayuso: Building a Pimple/Container from a YAML file

In a recent post to his site Gonzalo Ayuso shows how to create a Pimple container (a dependency injection container) from a YAML configuration definition using a simple handler already included in Pimple.

[In a conversation with Máximo Cuadros about Dependency Injection Containers] I said that I prefer Symfony´s DIC instead of Pimple, mainly because its configuration with YAML (or even xml) files. But In fact we can customise Pimple/Containers with YAML files in a similar way than we do it with Symfony's DIC. In this example we're going to see one way to do it.

While Pimple does come with the "Container" functionality to make this happen, Gonzalo points out that using it this way violates several of the SOLID design principles. Instead, he offers an alternate solution - using the Config component from Symfony to handle the creation of the container using an already established YAML format. He includes an example YAML configuration structure, the matching Pimple code for it and a code sample showing how the YAML is parsed into the same result. You can find the code on his GitHub account if you're interested in the full structure.
