php - Processing multiple Symfony bundle configs with one bundle -

i have lots of bundles have similar config files called rules.yml held in bundlename/resources/config/rules.yml each config file follows same structure:

bundle_name:     rules:       name:       items: []       requirements: [] 

i have 1 bundle called rulerbundle. bundle needs automatically load, validate , combine rules.yml found within other bundles. rulerbundle produce like:

bundle_a:     rules:       name: rule 1       items: ['first item']       requirements: ['second item', 'third item'] bundle_b:     rules:       name: rule 2       items: ['second item']       requirements: ['third item'] 

this should automatically updated when new bundle added rules.yml

questions

• should validate , process config within every bundle? lead code duplication validation rules same.

• how go finding , merging each of bundle configs rulerbundle

so can write dependencyinjection extension in top level bundle of validation. not sure should happen if invalid this:

// src/bundlename/dependencyinjection/bundleextension.php namespace acme\hellobundle\dependencyinjection;  use symfony\component\httpkernel\dependencyinjection\extension; use symfony\component\dependencyinjection\extension\prependextensioninterface; use symfony\component\dependencyinjection\containerbuilder;  class bundlename extends extension implements prependextensioninterface {     public function prepend(containerbuilder $container)     {         $bundles = $container->getparameter('kernel.bundles');         foreach ($bundles $name => $extension) {             $loader = new loader\yamlfileloader($container, new filelocator(__dir__.$name.'/../../resources/config'));             // load configuration file, returned array             $config = $loader->loadfile('rules.yml');              // validate contents of file             $this->validateconfig($config);              // append config specified bundle name "bundle_a", "bundle_a"             $container->prependextensionconfig($name, $config);         }     } } 

haven't tested of base idea. you'll need implement config validation method.
