Is posible to get the Module(s), Class and Method names in which we are?

Hi, for logging purposes I'd like to print the Modules, Class and Method in
with the logger is called. Imagine this case:

module App
  module TransportLayer
    class Server
      def get_data()
        ...
        ...
        logger.info "We are in XXXXXXX"
      end
    end
  end
end

I'd like to see:
  "We are in App::TransportLayer::Server#get_data"

Is it possible in anyway? The only I know how to do if getting the current
Class name by doing "self.class.to_s".

Thanks a lot.

Ok sorry, I can get the modules and classes via "self.class.to_s":
=> "App::Transport::Server::TCP"

The only I miss if the method name, is ti possible?

Thanks.

In 1.9 there is Method#name, but in 1.8.6 I think your best bet is to parse the output from Kernel#caller.

Yes, from caller().

Kind regards

Look at Facets: facets/ruby.rb. There is 1.8 implementation of
#__method__.

    # Retreive the current running method name.
