# di-order - require DI parameters to be sorted alphabetically

Injected dependencies should be sorted alphabetically.
If the second parameter is set to false, values which start and end with an underscore those underscores are stripped.
This means for example that `_$httpBackend_` goes before `_$http_`.

## Examples

The following patterns are considered problems with default config;

    /*eslint angular/di-order: 2*/

    // invalid
    angular.module('myModule').factory('myService', function($q, $http) {
        // ...
    }); // error: Injected values should be sorted alphabetically

    // invalid
    angular.module('myModule').controller('SomeController', function(myService, $http) {
        // ...
    }); // error: Injected values should be sorted alphabetically

    // invalid
    angular.module('myModule').filter('myFilter', function(someService, myService) {
        // ...
    }); // error: Injected values should be sorted alphabetically

The following patterns are **not** considered problems with default config;

    /*eslint angular/di-order: 2*/

    // valid
    angular.module('myModule').factory('myService', function($http, $location, $q, myService, someService) {
        // ...
    });

    // valid
    beforeEach(inject(function (_$compile_, $httpBackend, _$log_, _$rootScope_) {
        // ...
    }));

    // valid
    angular.module('myModule').factory('myService', function(CONFIG, URLs, authService, zero) {
        // ...
    });

The following patterns are considered problems when configured `true`:

    /*eslint angular/di-order: [2,true]*/

    // invalid
    beforeEach(inject(function ($httpBackend, _$compile_, _$log_, _$rootScope_) {
        // ...
    })); // error: Injected values should be sorted alphabetically

The following patterns are **not** considered problems when configured `true`:

    /*eslint angular/di-order: [2,true]*/

    // valid
    beforeEach(inject(function (_$compile_, $httpBackend, _$log_, _$rootScope_) {
        // ...
    }));

The following patterns are considered problems when configured `false`:

    /*eslint angular/di-order: [2,false]*/

    // invalid
    beforeEach(inject(function (_$compile_, $httpBackend, _$log_, _$rootScope_) {
        // ...
    })); // error: Injected values should be sorted alphabetically

The following patterns are **not** considered problems when configured `false`:

    /*eslint angular/di-order: [2,false]*/

    // valid
    beforeEach(inject(function ($httpBackend, _$compile_, _$log_, _$rootScope_) {
        // ...
    }));
