/**
* @ngdoc module
* @name ngMessages
* @description
*
* The `ngMessages` module provides enhanced support for displaying messages within templates
* (typically within forms or when rendering message objects that return key/value data).
* Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
* show and hide error messages specific to the state of an input field, the `ngMessages` and
* `ngMessage` directives are designed to handle the complexity, inheritance and priority
* sequencing based on the order of how the messages are defined in the template.
*
* Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
* `ngMessage`, `ngMessageExp` and `ngMessageDefault` directives.
*
* ## Usage
* The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
* (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
* case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
* {@link ngModel ngModel} directive.
*
* The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
* `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
* the `ngMessages` directive.
*
* Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
* have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
* directive.
*
* The `myField` field is a required input of type `email` with a maximum length of 15 characters.
*
* ```html
* <form name="myForm">
* <label>
* Enter text:
* <input type="email" ng-model="field" name="myField" required maxlength="15" />
* </label>
* <div ng-messages="myForm.myField.$error" role="alert">
* <div ng-message="required">Please enter a value for this field.</div>
* <div ng-message="email">This field must be a valid email address.</div>
* <div ng-message="maxlength">This field can be at most 15 characters long.</div>
* </div>
* </form>
* ```
*
* In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
* set to the `$error` object owned by the `myField` input in our `myForm` form.
*
* Within this element we then create separate elements for each of the possible errors that `myField` could have.
* The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
* setting `ng-message="required"` specifies that this particular element should be displayed when there
* is no value present for the required field `myField` (because the key `required` will be `true` in the object
* `myForm.myField.$error`).
*
* ### Message order
*
* By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
* than one message (or error) key is currently true, then which message is shown is determined by the order of messages
* in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
* to prioritize messages using custom JavaScript code.
*
* Given the following error object for our example (which informs us that the field `myField` currently has both the
* `required` and `email` errors):
*
* ```javascript
* <!-- keep in mind that ngModel automatically sets these error flags -->
* myField.$error = { required : true, email: true, maxlength: false };
* ```
* The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
* Once the user types a single character, the `required` message will disappear (since the field now has a value)
* but the `email` message will be visible because it is still applicable.
*
* ### Displaying multiple messages at the same time
*
* While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
* be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
*
* ```html
* <!-- attribute-style usage -->
* <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
*
* <!-- element-style usage -->
* <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
* ```
*
* ## Reusing and Overriding Messages
* In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
* template. This allows for generic collection of messages to be reused across multiple parts of an
* application.
*
* ```html
* <script type="text/ng-template" id="error-messages">
* <div ng-message="required">This field is required</div>
* <div ng-message="minlength">This field is too short</div>
* </script>
*
* <div ng-messages="myForm.myField.$error" role="alert">
* <div ng-messages-include="error-messages"></div>
* </div>
* ```
*
* However, including generic messages may not be useful enough to match all input fields, therefore,
* `ngMessages` provides the ability to override messages defined in the remote template by redefining
* them within the directive container.
*
* ```html
* <!-- a generic template of error messages known as "my-custom-messages" -->
* <script type="text/ng-template" id="my-custom-messages">
* <div ng-message="required">This field is required</div>
* <div ng-message="minlength">This field is too short</div>
* </script>
*
* <form name="myForm">
* <label>
* Email address
* <input type="email"
* id="email"
* name="myEmail"
* ng-model="email"
* minlength="5"
* required />
* </label>
* <!-- any ng-message elements that appear BEFORE the ng-messages-include will
* override the messages present in the ng-messages-include template -->
* <div ng-messages="myForm.myEmail.$error" role="alert">
* <!-- this required message has overridden the template message -->
* <div ng-message="required">You did not enter your email address</div>
*
* <!-- this is a brand new message and will appear last in the prioritization -->
* <div ng-message="email">Your email address is invalid</div>
*
* <!-- and here are the generic error messages -->
* <div ng-messages-include="my-custom-messages"></div>
* </div>
* </form>
* ```
*
* In the example HTML code above the message that is set on required will override the corresponding
* required message defined within the remote template. Therefore, with particular input fields (such
* email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
* while more generic messages can be used to handle other, more general input errors.
*
* ## Dynamic Messaging
* ngMessages also supports using expressions to dynamically change key values. Using arrays and
* repeaters to list messages is also supported. This means that the code below will be able to
* fully adapt itself and display the appropriate message when any of the expression data changes:
*
* ```html
* <form name="myForm">
* <label>
* Email address
* <input type="email"
* name="myEmail"
* ng-model="email"
* minlength="5"
* required />
* </label>
* <div ng-messages="myForm.myEmail.$error" role="alert">
* <div ng-message="required">You did not enter your email address</div>
* <div ng-repeat="errorMessage in errorMessages">
* <!-- use ng-message-exp for a message whose key is given by an expression -->
* <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
* </div>
* </div>
* </form>
* ```
*
* The `errorMessage.type` expression can be a string value or it can be an array so
* that multiple errors can be associated with a single error message:
*
* ```html
* <label>
* Email address
* <input type="email"
* ng-model="data.email"
* name="myEmail"
* ng-minlength="5"
* ng-maxlength="100"
* required />
* </label>
* <div ng-messages="myForm.myEmail.$error" role="alert">
* <div ng-message-exp="'required'">You did not enter your email address</div>
* <div ng-message-exp="['minlength', 'maxlength']">
* Your email must be between 5 and 100 characters long
* </div>
* </div>
* ```
*
* Feel free to use other structural directives such as ng-if and ng-switch to further control
* what messages are active and when. Be careful, if you place ng-message on the same element
* as these structural directives, AngularJS may not be able to determine if a message is active
* or not. Therefore it is best to place the ng-message on a child element of the structural
* directive.
*
* ```html
* <div ng-messages="myForm.myEmail.$error" role="alert">
* <div ng-if="showRequiredError">
* <div ng-message="required">Please enter something</div>
* </div>
* </div>
* ```
*
* ## Animations
* If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
* `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
* the DOM by the `ngMessages` directive.
*
* Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
* class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
* messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
* hook into the animations whenever these classes are added/removed.
*
* Let's say that our HTML code for our messages container looks like so:
*
* ```html
* <div ng-messages="myMessages" class="my-messages" role="alert">
* <div ng-message="alert" class="some-message">...</div>
* <div ng-message="fail" class="some-message">...</div>
* </div>
* ```
*
* Then the CSS animation code for the message container looks like so:
*
* ```css
* .my-messages {
* transition:1s linear all;
* }
* .my-messages.ng-active {
* // messages are visible
* }
* .my-messages.ng-inactive {
* // messages are hidden
* }
* ```
*
* Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
* and leave animation is triggered for each particular element bound to the `ngMessage` directive.
*
* Therefore, the CSS code for the inner messages looks like so:
*
* ```css
* .some-message {
* transition:1s linear all;
* }
*
* .some-message.ng-enter {}
* .some-message.ng-enter.ng-enter-active {}
*
* .some-message.ng-leave {}
* .some-message.ng-leave.ng-leave-active {}
* ```
*
* {@link ngAnimate See the ngAnimate docs} to learn how to use JavaScript animations or to learn
* more about ngAnimate.
*
* ## Displaying a default message
* If the ngMessages renders no inner ngMessage directive (i.e. when none of the truthy
* keys are matched by a defined message), then it will render a default message
* using the {@link ngMessageDefault} directive.
* Note that matched messages will always take precedence over unmatched messages. That means
* the default message will not be displayed when another message is matched. This is also
* true for `ng-messages-multiple`.
*
* ```html
* <div ng-messages="myForm.myField.$error" role="alert">
* <div ng-message="required">This field is required</div>
* <div ng-message="minlength">This field is too short</div>
* <div ng-message-default>This field has an input error</div>
* </div>
* ```
*

*
* @description
* `ngMessages` is a directive that is designed to show and hide messages based on the state
* of a key/value object that it listens on. The directive itself complements error message
* reporting with the `ngModel` $error object (which stores a key/value state of validation errors).
*
* `ngMessages` manages the state of internal messages within its container element. The internal
* messages use the `ngMessage` directive and will be inserted/removed from the page depending
* on if they're present within the key/value object. By default, only one message will be displayed
* at a time and this depends on the prioritization of the messages within the template. (This can
* be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
*
* A remote template can also be used (With {@link ngMessagesInclude}) to promote message
* reusability and messages can also be overridden.
*
* A default message can also be displayed when no `ngMessage` directive is inserted, using the
* {@link ngMessageDefault} directive.
*
