AngularJS filter to create links out of URLs

filters.js

app.filter('parseUrl', function() {
    var  //URLs starting with http://, https://, or ftp://
      replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim,
	    //URLs starting with "www." (without // before it, or it'd re-link the ones done above).
	    replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim,
	    //Change email addresses to mailto:: links.
	    replacePattern3 = /(\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,6})/gim;

	    return function(text, target, otherProp) {        
	        angular.forEach(text.match(replacePattern1), function(url) {
	        	text = text.replace(replacePattern1, "<a href=\"$1\" target=\"_blank\">$1</a>");
	        });
	        angular.forEach(text.match(replacePattern2), function(url) {
	        	text = text.replace(replacePattern2, "$1<a href=\"http://$2\" target=\"_blank\">$2</a>");
	        });
	        angular.forEach(text.match(replacePattern3), function(url) {
	        	text = text.replace(replacePattern3, "<a href=\"mailto:$1\">$1</a>");
	        });

	        return text;        
	    };
	});

Seems to cause recursion. Doesn't work as expected.

Produces nested tags when multiple links. Removing the forEachs does the trick since already global regexs

Doesn't work if you already have links in your string... then you again get double nested links. Needs a better regex.

Good
