Magento 2: get a list of all plugins (interceptors) and preferences

Question

Is there a way I can retrieve the list of all plugins (with the methods they're plugged onto) and all preferences (and their original class) on a Magento 2 install.

Answer 1

For getting all available list of plugins:

Go to vendor/magento/framework/Interception/PluginList/PluginList.php find method merge

public function merge(array $config)
{
   // default code
    echo "<pre>";
    print_r($this->_data);
    die();  
}

For getting all available list of preferences:

vendor/magento/framework/ObjectManager/Config/Mapper/Dom.php find method convert

public function convert($config)
{
// default code
   echo "<pre>";
   print_r($output);
   die();
}
