angularJS directives

pseudo code:

var myModule = angular.module(...);

myModule.directive('namespaceDirectiveName', function factory(injectables) {
  var directiveDefinitionObject = {
    restrict: string,
    priority: number,
    template: string,
    templateUrl: string,
    replace: bool,
    transclude: bool,
    scope: bool or object,
    controller: function controllerConstructor($scope,
                                               $element,
                                               $attrs,
                                               $transclude),
    require: string,
    link: function postLink(scope, iElement, iAttrs) { ... },
    compile: function compile(tElement, tAttrs, transclude) {
      return {
        pre: function preLink(scope, iElement, iAttrs, controller) { ... },
        post: function postLink(scope, iElement, iAttrs, controller) { ... }
      }
    }
  };
  return directiveDefinitionObject;
});
**Property** **Purpose**
restrict Declare how directive can be used in a template as an element, attribute, class, comment, or any combination.
priority Set the order of execution in the template relative to other directives on the element.
template Specify an inline template as a string. Not used if you’re specifying your template as a URL.
templateUrl Specify the template to be loaded by URL. This is not used if you’ve specified an inline template as a string.
replace If true, replace the current element. If false or unspecified, append this directive to the current element.
transclude Lets you move the original children of a directive to a location inside the new template.
scope Create a new scope for this directive rather than inheriting the parent scope.
controller Create a controller which publishes an API for communicating across directives.
require Require that another directive be present for this directive to function correctly.
link Programmatically modify resulting DOM element instances, add event listeners, and set up data binding.
compile Programmatically modify the DOM template for features across copies of a directive, as when used in ng-repeat. Your compile function can also return link functions to modify the resulting element instances.
