# directive-restrict - disallow any other directive restrict than 'A' or 'E'

Not all directive restrictions may be desirable.
Also it might be desirable to define default restrictions, or explicitly not.
The default configuration limits the restrictions `AE` and disallows explicitly specifying a default.
("directive-restrict": [0, {"restrict": "AE", "explicit": "never"}])

## Examples

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

    /*eslint angular/directive-restrict: 2*/

    // valid
    angular.module('myModule').directive('helloWorld', function () {
        return {
            template: '<h2>Hello World!</h2>',
            restrict: 'A' // also allowed: A, E, AE, EA
        };
    });

    // valid
    angular.module('myModule').directive('helloWorld', function () {
        return {
            template: '<h2>Hello World!</h2>'
            // no explicit restrict is allowed by default
        };
    });

The following patterns are considered problems when configured `{"explicit":"always"}`:

    /*eslint angular/directive-restrict: [2,{"explicit":"always"}]*/

    // invalid
    angular.module('myModule').directive('helloWorld', function () {
        return {
            template: '<h2>Hello World!</h2>'
        };
    }); // error: Missing directive restriction

The following patterns are considered problems when configured `{"explicit":"never"}`:

    /*eslint angular/directive-restrict: [2,{"explicit":"never"}]*/

    // invalid
    angular.module('myModule').directive('helloWorld', function () {
        return {
            template: '<h2>Hello World!</h2>',
            restrict: 'AE'
        };
    }); // error: No need to explicitly specify a default directive restriction

The following patterns are considered problems when configured `{"restrict":"A"}`:

    /*eslint angular/directive-restrict: [2,{"restrict":"A"}]*/

    // invalid
    angular.module('myModule').directive('helloWorld', function () {
        return {
            template: '<h2>Hello World!</h2>',
            restrict: 'E'
        };
    }); // error: Disallowed directive restriction. It must be one of A in that order
