/**
* @ngdoc module
* @name ngMessageFormat
* @packageName angular-message-format
*
* @description
*
* ## What is ngMessageFormat?
*
* The ngMessageFormat module extends the AngularJS {@link ng.$interpolate `$interpolate`} service
* with a syntax for handling pluralization and gender specific messages, which is based on the
* [ICU MessageFormat syntax][ICU].
*
* See [the design doc][ngMessageFormat doc] for more information.
*
* [ICU]: http://userguide.icu-project.org/formatparse/messages#TOC-MessageFormat
* [ngMessageFormat doc]: https://docs.google.com/a/google.com/document/d/1pbtW2yvtmFBikfRrJd8VAsabiFkKezmYZ_PbgdjQOVU/edit
*
* ## Examples
*
* ### Gender
*
* This example uses the "select" keyword to specify the message based on gender.
*
* <example name="ngMessageFormat-example-gender" module="msgFmtExample" deps="angular-message-format.js">
* <file name="index.html">
* <div ng-controller="AppController">
* Select Recipient:<br>
<select ng-model="recipient" ng-options="person as person.name for person in recipients">
</select>
<p>{{recipient.gender, select,
male {{{recipient.name}} unwrapped his gift. }
female {{{recipient.name}} unwrapped her gift. }
other {{{recipient.name}} unwrapped their gift. }
}}</p>
* </div>
* </file>
* <file name="script.js">
* function Person(name, gender) {
* this.name = name;
* this.gender = gender;
* }
*
* var alice = new Person('Alice', 'female'),
* bob = new Person('Bob', 'male'),
* ashley = new Person('Ashley', '');
*
* angular.module('msgFmtExample', ['ngMessageFormat'])
* .controller('AppController', ['$scope', function($scope) {
* $scope.recipients = [alice, bob, ashley];
* $scope.recipient = $scope.recipients[0];
* }]);
* </file>
* </example>
*
* ### Plural
*
* This example shows how the "plural" keyword is used to account for a variable number of entities.
* The "#" variable holds the current number and can be embedded in the message.
*
* Note that "=1" takes precedence over "one".
*
* The example also shows the "offset" keyword, which allows you to offset the value of the "#" variable.
*
* <example name="ngMessageFormat-example-plural" module="msgFmtExample" deps="angular-message-format.js">
* <file name="index.html">
* <div ng-controller="AppController">
* <button ng-click="recipients.pop()" id="decreaseRecipients">decreaseRecipients</button><br>
* Select recipients:<br>
* <select multiple size=5 ng-model="recipients" ng-options="person as person.name for person in people">
* </select><br>
* <p>{{recipients.length, plural, offset:1
* =0 {{{sender.name}} gave no gifts (\#=#)}
* =1 {{{sender.name}} gave a gift to {{recipients[0].name}} (\#=#)}
* one {{{sender.name}} gave {{recipients[0].name}} and one other person a gift (\#=#)}
* other {{{sender.name}} gave {{recipients[0].name}} and # other people a gift (\#=#)}
* }}</p>
* </div>
* </file>
*
* <file name="script.js">
* function Person(name, gender) {
* this.name = name;
* this.gender = gender;
* }
*
* var alice = new Person('Alice', 'female'),
* bob = new Person('Bob', 'male'),
* sarah = new Person('Sarah', 'female'),
* harry = new Person('Harry Potter', 'male'),
* ashley = new Person('Ashley', '');
*
* angular.module('msgFmtExample', ['ngMessageFormat'])
* .controller('AppController', ['$scope', function($scope) {
* $scope.people = [alice, bob, sarah, ashley];
* $scope.recipients = [alice, bob, sarah];
* $scope.sender = harry;
* }]);
* </file>
*
* <file name="protractor.js" type="protractor">
* describe('MessageFormat plural', function() {
*
* it('should pluralize initial values', function() {
* var messageElem = element(by.binding('recipients.length')),
* decreaseRecipientsBtn = element(by.id('decreaseRecipients'));
*
* expect(messageElem.getText()).toEqual('Harry Potter gave Alice and 2 other people a gift (#=2)');
* decreaseRecipientsBtn.click();
* expect(messageElem.getText()).toEqual('Harry Potter gave Alice and one other person a gift (#=1)');
* decreaseRecipientsBtn.click();
* expect(messageElem.getText()).toEqual('Harry Potter gave a gift to Alice (#=0)');
* decreaseRecipientsBtn.click();
* expect(messageElem.getText()).toEqual('Harry Potter gave no gifts (#=-1)');
* });
* });
* </file>
* </example>
*
* ### Plural and Gender together
*
* This example shows how you can specify gender rules for specific plural matches - in this case,
* =1 is special cased for gender.
* <example name="ngMessageFormat-example-plural-gender" module="msgFmtExample" deps="angular-message-format.js">
* <file name="index.html">
* <div ng-controller="AppController">
Select recipients:<br>
<select multiple size=5 ng-model="recipients" ng-options="person as person.name for person in people">
</select><br>
<p>{{recipients.length, plural,
=0 {{{sender.name}} has not given any gifts to anyone.}
=1 { {{recipients[0].gender, select,
female { {{sender.name}} gave {{recipients[0].name}} her gift.}
male { {{sender.name}} gave {{recipients[0].name}} his gift.}
other { {{sender.name}} gave {{recipients[0].name}} their gift.}
}}
}
other {{{sender.name}} gave {{recipients.length}} people gifts.}
}}</p>
</file>
* <file name="script.js">
* function Person(name, gender) {
* this.name = name;
* this.gender = gender;
* }
*
* var alice = new Person('Alice', 'female'),
* bob = new Person('Bob', 'male'),
* harry = new Person('Harry Potter', 'male'),
* ashley = new Person('Ashley', '');
*
* angular.module('msgFmtExample', ['ngMessageFormat'])
* .controller('AppController', ['$scope', function($scope) {
* $scope.people = [alice, bob, ashley];
* $scope.recipients = [alice];
* $scope.sender = harry;
* }]);
* </file>
</example>
