Angular Hint Interpolation

This hinting module is part of the overall tool AngularHint that aims to help you spend less time finding silent errors in your code and more time programming. Loading this module will provide warnings specific to AngularJS interpolation.

See the AngularHintInterpolation NPM Module.

##Usage

Install the AngularHint NPM module and use ng-hint or ng-hint-include='interpolation' to enable AngularHintInterpolation. Further installation information is available on the main AngularHint repository.

##Features

• Notifies of undefined parts of interpolation chains
• Suggests closest variable to the first undefined variable in chain

#### Undefined Parts Warning AngularHintInterpolation addresses the problem of identifying where (within a chain) objects become undefined. For example, in the code below one would be notified that data.results[0].urls was found to be undefined in the interpolation data.results[0].entities.urls.main_url.

//html implementation
<a ng-href="{{data.results[0].urls.main_url}}">Link to Post</a>

//controller implementation
$scope.data = {
  "completed_in": 0.031,
  "refresh_url": "?sinceid=122078461840982016&q=blue%20angels",
  "results": [
    {
      "entities":{
        "urls": {
          "condensed_url": "http://t.co/L9JXJ2ee",
          "main_url": "http://t.co/imgs/users/venrov/L9JXJ2ee"
        }
      }
    }]
}

#### Variable Suggestion If your value that evaluates to undefined is close enough to an actual value present on the scope, AngularHintInterpolation will suggest an alternative value. Using the HTML code below, you would be notified that data.results[0].entity was undefined but that you should try entities.

//html implementation
<a ng-href="{{data.results[0].entity.urls.main_url}}">Link to Post</a>

//controller implementation
$scope.data = {
  "completed_in": 0.031,
  "refresh_url": "?sinceid=122078461840982016&q=blue%20angels",
  "results": [
    {
      "entities":{
        "urls": {
          "condensed_url": "http://t.co/L9JXJ2ee",
          "main_url": "http://t.co/imgs/users/venrov/L9JXJ2ee"
        }
      }
    }]
}
