According to Rails engines extending functionality in Rails 2.x one could do
Rails::Initializer.new(Rails.configuration).plugin_loader.engines
This code is not working in Rails 3
ActionController::RoutingError (undefined method `new' for Rails::Initializer:Module):
config/application.rb:12:in `require_or_load'
What do I need to do in Rails 3 to get such list of engines?
This is needed for Extending controllers of a Rails 3 Engine in the main app
As of 5/10/2011 and Rails 3.1 beta, it's now
Rails::Application::Railties.engines
