my bot inherits from irc.IRCClient, when it sends a message to another user who isnt online irc_ERR_NOSUCHNICK(self, prefix, command) is called. how can i react to that message, my code is called with: class mybot(irc.IRCClient): ... if __name__ == "__main__": factory = XdccBotFactory( channel, nickname, xdccbot, xdccrequests ) reactor.connectTCP( server, 6667, factory ) in irc_ERR_NOSUCHNICK... i got: error_message = "%s bot is not connected to server" % now.strftime("%Y-%m-%d %H:%M:%S") log.warning(error_message) which works. but what i really would like to have is: if __name__ == "__main__": factory = XdccBotFactory( channel, nickname, xdccbot, xdccrequests ) reactor.connectTCP( server, 6667, factory ) if "bot not online": "send message to antoher user" so basically i need the information that irc_ERR_... was called after the reactor was started. how do you do that?
