In Angular, match the current route to set the active element in a navigation bar, etc.

/*
 * In your controller, create a function that compares the current location to a regular expression.
 */
$scope.routeMatches = function (fragment) {
  var matcher = new RegExp('^' + fragment + '$', ['i']);
  return matcher.test($location.path());
};

/*
 * In your partial, use the above function to assign an appropriate 'active' CSS class.
 * You can also drive another directive like ng-show, etc.

<li ng-class="{active: routeMatches('/templates.*')}">
  <a href="#/templates/manage"><i class="icon icon-tasks bigIcon"></i> Templates</a>
