Some useful functions when developing ember apps

lib.coffee

window.delay = (duration, toRun) ->
  Ember.run.later(toRun, duration)

window.waitUntil = (context, interval, toRun, condition) ->
  if condition.call(context)
    return toRun.call(context)
    
  delay interval, ->
    waitUntil(context, interval, toRun, condition)

Ember.Object.reopenClass
  createFromUnderscoreKeys: (options) ->
    keys = $.makeArray(Ember.keys(options))
    camelKeys = Ember.EnumerableUtils.map keys, (key) ->
      key.camelize()
    Ember.EnumerableUtils.forEach keys, (key, i) ->
      options[camelKeys[i]] = options[key]
      delete options[key]
    Ember.Object.create(options)
