I need to be able to match a path like '/@someusername' with angular ui router but can't figure out the regex for it. What I have are routes like the following $stateProvider .state('home', {url:'/', templateUrl:'/template/path.html'}) .state('author', {url:'/{username:[regex-to-match-@username-here]}'}) .state('info', {url:'/:slug', templateUrl:'/template/path.html'}) .state('entry', {url:'/:type/:slug', templateUrl:'/template/path.html'}); I need a bit of regex for the 'author' route that will match @usernames. Currently, everything I try is caught by the 'entry' route.
