In this POC, I used Silex as a micro-framework for developing a WordPress plugin to validate if Silex is small but efficient enough to wrap informal and not object oriented code into more clean and service oriented code.
The main "benefits" are:
Use Pimple as a service container for various plugin services
Use HTTP Foundation components (Request & Response) to handle all the HTTP layer interactions
Use Twig as a template engine. eg the plugin setting page
Use the EventDispatcher component as a complementary of WordPress Actions
Use Monolog to trace what's happening under the hood
...
That's what's going to happen inside Uncle Bob head if by chance he finds this repo:
Why would someone need to use Silex as a developing platform for a WordPress plugin?!!!
What kind of nonsense is that?!! Putting business rules inside a tool that's itself bundled inside another tool!!! The ULTIMATE INFINITE ENSLAVEMENT this hack screams !
What's the purpose of the plugin? Why don't you talk about the business instead of WordPress or Silex, those are just tools
Arghhh... God help you, cause the tools will not!
So you're warned, don't try this at home or do it at your own risk :)
