==== Parsing Twitter Usernames, Hashtags and URLs with JavaScript ====
 
-- Demo 1. Parsing URLs
String.prototype.parseURL = function() {
    return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&~\?\/.=]+/g, function(url) {
        return url.link(url);
    });
};
test = "Simon Whatley's online musings can be found at: http://www.WilzonMB.com";
document.writeln(test.parseURL());
 
--Demo 2. Parsing Twitter Usernames
String.prototype.parseUsername = function() {
    return this.replace(/[@]+[A-Za-z0-9-_]+/g, function(u) {
        var username = u.replace("@","")
        return u.link("http://twitter.com/"+username);
    });
};
test = "@whatterz is writing a post about JavaScript";
document.writeln(test.parseUsername());
 
--Demo 3. Parsing Twitter Hashtags
String.prototype.parseHashtag = function() {
    return this.replace(/[#]+[A-Za-z0-9-_]+/g, function(t) {
        var tag = t.replace("#","%23")
        return t.link("http://search.twitter.com/search?q="+tag);
    });
};
test = "Simon is writing a post about #twitter, #javascript and parsing hashtags as URLs";
document.writeln(test.parseHashtag());
 
 
--Demo 4. Cascading methods
var test = "@whatterz is writing a blog post about #twitter and #javascript, 
which can be found at http://www.simonwhatley.co.uk/examples/twitter/prototype and
 http://www.simonwhatley.co.uk/parsing-twitter-usernames-hashtags-and-urls-with-javascript /cc @simonwhatley";
document.writeln(test.parseURL().parseUsername().parseHashtag());
