Yes.
The file parser.php contains this:
//
// Make hyperlinks clickable
//
function do_clickable($text)
{
global $pun_user;
$text = ' '.$text;
$text = preg_replace('#([\s\(\)])(https?|ftp|news){1}://([\w\-]+\.([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^"\s\(\)<\[]*)?)#ie', '\'$1\'.handle_url_tag(\'$2://$3\')', $text);
$text = preg_replace('#([\s\(\)])(www|ftp)\.(([\w\-]+\.)*[\w]+(:[0-9]+)?(/[^"\s\(\)<\[]*)?)#ie', '\'$1\'.handle_url_tag(\'$2.$3\', \'$2.$3\')', $text);
return substr($text, 1);
}
Copy, rename and modify the function to handle IRC links. Then call it at the appropriate places (i.e. where do_clickable is called usually).
