Use case

Usually, you develop your website using one or several custom bundles as this is a best practice. However, dealing with core bundles semantic configuration can be a bit tedious if you maintain it in the main ezpublish/config/ezpublish.yml configuration file.

This recipe will show you how to import configuration from a bundle the manual way and the implicit way.

The manual way

This is the simplest way of doing and it has the advantage to be explicit. The idea is to use the imports statement in your main ezpublish.yml:

If you want to import configuration for development use only, you can do so in your ezpublish_dev.yml (wink)

The implicit way

Info

Compatible with eZ Publish 5.1+ / Symfony 2.2+ as it uses Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface which is available as of Symfony 2.2 (more info on Symfony cookbook).

Info
titleRegarding performance

Service container extensions are called only when the container is being compiled, so there is nothing to worry about regarding performance.

Tip

Loading configuration this way lets you override settings in your Configuration loaded this way will be overridden by the main ezpublish.yml file.
