Re: Where did the app object go?

[recursor]

Interesting. I didn't get the console error that you did, but that must be 
because I'm running r970 and I assume you're running r1009?

I can't get your re-formed example to work with r970 either. I guess it's time 
I do a git clone of the sources so I can keep on top of all the bug fixes and 
get the 'app' method.  By the way, I didn't see the 'app' method either when I 
looked at stack's methods, but I though I was just missing something.  Turns 
out I am - the latest version.

Thanks guys

Aha. So, after fully reading the Rules, I developed a theory that the
example shown there is all wrong because inside the app() block, self
is changed to your app, which has no @stack instance. Running your
sample code, that seems confirmed with the error "undefined method
'append' for nil:NilClass" shown in the console.

This works:

  class Messenger
    def initialize(stack)
      @stack = stack
    end

    def add(msg)
      @stack.app do
        @messages.append do
          para msg
        end
      end
    end
  end

  Shoes.app do
    @messages  = stack
    @messenger = Messenger.new @messages

    button "go" do
      @messenger.add "dy-no-mite"
    end
  end
