You can inject the constant anywhere that is injectable including the directive definition itself, the controller of a directive, the link function, et. al.

angular.module('my.directive', []).directive('name', ['ngSettings', function (ngSettings) {
    // do things with ngSettings
    return {};
}]);

By the way I wouldn't name anything you define yourself as ng -- that should be preserved for things in the ng module or that Angular itself created.

The same way as you would use any other dependency.

angular.module('my.directive', []).directive('my', ['ngSettings', function (ngSettings) {
    ...
}]);

Constants are particular cases of providers:

The remaining four recipe types — Value, Factory, Service and Constant — are just syntactic sugar on top of a provider recipe.
