Overview

Base view class. It’s used to call the magical method_messing stuff to parse the view object files into actual objects.

Intentionally use a class variable to hald views. Once they’re all loaded they are all loaded for everyone. rubocop:disable Style/ClassVars

def initialize(interface)
  @interface = interface
  # Dirty trick because we're loading all of view classes from files and
  # then initializing them, calling their layout methods to do magic.
  # The view class knows what views are loaded.
  return if @@loaded_views.include?(self.class)

end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(element, *args, &_block) ⇒ Object

This creates a new element instance whenever it’s called. Because of that we can’t keep state in any element objects. That seems like a good thing, actually. Called by layout method on views.

Hard to make shorter. rubocop:disable Metrics/MethodLength

.url ⇒ Object

BUGBUG #1: Some view in a generic app should not have URL.

BUGBUG: Kludgy. What do I really want to do here? Make it easy to define a view’s default url and also matchers for view urls for views with variable urls? rubocop:disable Style/TrivialAccessors
