Handlebars.js: linkify helper #cc #handlebars

handlebars.linkify.js

Handlebars.registerHelper('linkify', function (text) {
    text = text.replace(/(https?:\/\/\S+)/gi, function (s) {
        return '<a href="' + s + '">' + s + '</a>';
    });

    text = text.replace(/(^|)@(\w+)/gi, function (s) {
        return '<a href="http://twitter.com/' + s + '">' + s + '</a>';
    });

    text = text.replace(/(^|)#(\w+)/gi, function (s) {
        return '<a href="http://search.twitter.com/search?q=' + s.replace(/#/,'%23') + '">' + s + '</a>';
     });
    return new Handlebars.SafeString(text);
});

I was having trouble with trailing punctuation (http://google.com,) so I changed to this regex

/(http|ftp|https)://([\w-]+(.[\w-]+)+)([\w.,@?^=%&:/+#-]*[\w@?^=%&/+#-])?/gi
