Visualizing the O’Reilly Connection Network

Dissident – More Ruby Dependency Injection

Christian Neukirchen, Ruby prodigy with an unrememberable last name, has not only written a nice new Dependency Injection library, but a nice overview of DI itself.
API sample:

class Application
  inject :logger
  def do_stuff
    logger.log "doing stuff"
  end
end

class MyContainer < Dissident::Container

  provide :logger, Logger

end
Dissident.with MyContainer do

  a = Application.new

  a.do_stuff

end
