AngularJS filter to create links out of URLs
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

@geoidesic

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