For example: ``linkify("Hello http://tornadoweb.org!")`` would return ``Hello <a href="http://tornadoweb.org">http://tornadoweb.org</a>!`` Parameters: * ``shorten``: Long urls will be shortened for display. * ``extra_params``: Extra text to include in the link tag, or a callable taking the link as an argument and returning the extra text e.g. ``linkify(text, extra_params='rel="nofollow" class="external"')``, or:: def extra_params_cb(url): if url.startswith("http://example.com"): return 'class="internal"' else: return 'class="external" rel="nofollow"' linkify(text, extra_params=extra_params_cb) * ``require_protocol``: Only linkify urls which include a protocol. If this is False, urls such as www.facebook.com will also be linkified. * ``permitted_protocols``: List (or set) of protocols which should be linkified, e.g. ``linkify(text, permitted_protocols=["http", "ftp", "mailto"])``.
