Global utility for establishing, managing, and queuing actions with dependencies.

Wrapper function to return an action instance.

• *name: The name of the action you would like to perform.

An instance of action, set with the provided name. The action instance is meant to be used with the ifSatisfied or whenSatisfied methods.

perform('view:model:update').ifSatisfied(function (done) {
  // Do something
  done();
})

Add dependencies to actions.

• *map: A key value pairs where the key represents the action name and the value is an array holding the specified action dependencies.

perform.addDependencies({
  'view:model:save': ['view:model:create']
});

Reset the state for the specified name. The passed name is namepsace aware. Passing in view:model would reset all child actions (view:model:save, view:model:create, etc..)

• *name: The name of the action you would like to perform.

perform.restart('view');

Perform the specified action only if all dependencies are satisfied.

• *fn: The action you would like to execute if dependencies are satisfied.
• context: The context in which to call the provided fn.

Instance of action.

perform('view:model:save').ifSatisfied(function (done) {
  // Do something
  done();
})

Perform the specified action when all dependencies are satisfied.

• *fn: The action you would like to execute when dependencies are satisfied.
• context: The context in which to call the provided fn.

Instance of action.

perform('view:model:update').whenSatisfied(function (done) {
  // Do something
  done();
});

Update the state of the performed action. This is also passed as the first argument into your action fn. This can be useful for sync operations.

perform('view:model:displayErr').ifSatisfied(function () {
  // Do something
}).done();

perform.addDependencies({
  'view:model:update': ['view:model:get']
});

var view = {
  initialize  onShow: function () {
    perform.restart('view');
  },
  
  onClose: function () {
    perform('view:model:update).whenSatisfied(function (done) {
      var $input = $('.input-selector');
      
      // If model has changed save
    if (model.attributes.body !== $input.val()) {
      model.update({ success: done });
    } else {
      done();
    }
    });
  }
};
