    a.href = url;
    return {
        source: url,
        protocol: a.protocol.replace(':', ''),
        host: a.hostname,
        port: a.port,
        query: a.search,
        params: (function () {
            var ret = {},
                seg = a.search.replace(/^\?/, '').split('&'),
                len = seg.length,
                i = 0,
                s;
            for (; i < len; i++) {
                if (!seg[i]) {
                    continue;
                }
                s = seg[i].split('=');
                ret[s[0]] = s[1];
            }
            return ret;
        })(),
        file: (a.pathname.match(/\/([^\/?#]+)$/i) || [, ''])[1],
        hash: a.hash.replace('#', ''),
        path: a.pathname.replace(/^([^\/])/, '/$1'),
        relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [, ''])[1],
        segments: a.pathname.replace(/^\//, '').split('/')
    };
}

console.log(parse_URL('https://github.com/pubnub/python/search?utf8=%E2%9C%93&q=python'));

Output:

{"source":"https://github.com/pubnub/python/search?utf8=%E2%9C%93&q=python","protocol":"https","host":"github.com","port":"","query":"?utf8=%E2%9C%93&q=python","params":{"utf8":"%E2%9C%93","q":"python"},"file":"search","hash":"","path":"/pubnub/python/search","relative":"/pubnub/python/search?utf8=%E2%9C%93&q=python","segments":["pubnub","python","search"]}
