adapting classes for angular

# in order to do this:
# <div ng:controller="MyController">{{message}}</div>

# I used to be able to
class MyController
  constructor:->
    @message = "Hello World"

# Now I need:

class MyControllerWithScope
  constructor:($scope)->
    $scope.message = "Hello World"

# But if you want original way you now can do
adaptForAngular(MyController)

--------------------

adaptForAngular = (clazz, injections...)->
  injections.push "$scope"
  @[clazz.name] = (args..., scope)->
    controller = new clazz()
    angular.extend scope, controller
    scope.initializeInjections? args...
    scope.$scope = scope

  @[clazz.name].$inject = injections

MyController = ($scope, $otherService)->
  someInternalField = "secret"

  someHiddenHelper = ()->
    #  I can use $scope and $otherService in here
    return $otherService.doStuff($scope.someField)

  $scope.someScopeHelper = ()->
    $scope.fieldToUpdate = someHiddenHelper()

  # I can initialize $scope here
  $scope.someField = "myValue"
