im sure youre solution is just fine, could you show me how you would
contruct isBotOnline?
im assuming that code would go into the class "mybot", next to
irc_ERR_NOSUCKNICK?
The problem with just doing that is that there is no affirmative
response that a message was sent, so there's no way to fire the
deferred successfully if that's all you're doing. Instead, you can
use the ISON command to determine if the bot is online (and of course,
the bot might go offline between the check and sending the message, so
you will need to handle that case somehow too).
Since doing this is somewhat obscure, here's a working script that
just checks if a nick specified on the command line is online on freenode:
*from* *__future__* *import* print_function
*from* *twisted.internet.defer* *import* Deferred, inlineCallbacks
*from**twisted.words.protocols.irc**import*IRCClient
*from**twisted.internet.endpoints**import*clientFromString
*from**twisted.internet.protocol**import*Factory
*class* *mybot*(IRCClient, object):
*def* __init__(self):
self._isonQueue = []
self.motdReceived = Deferred()
*def* irc_RPL_ISON(self, prefix, params):
username, d = self._isonQueue.pop(0)
d.callback((username *in* params[1]))
*def* isOnline(self, username):
d = Deferred()
self.sendLine("ISON " + username)
self._isonQueue.append((username, d))
*return* d
*def* irc_RPL_ENDOFMOTD(self, prefix, params):
self.motdReceived.callback(None)
@inlineCallbacks
*def* main(reactor, nick):
endpoint = clientFromString(reactor, "tcp:chat.freenode.net:6667")
proto = *yield* endpoint.connect(Factory.forProtocol(mybot))
*print*("Waiting for MOTD...")
*yield* proto.motdReceived
*print*("Querying...")
isOnline = *yield* proto.isOnline(nick)
*if* isOnline:
*print*(nick, "is online!")
*else*:
*print*(nick, "is *NOT* online!")
*from**twisted.internet.task**import*react
*from**sys**import*argv
react(main, argv[1:])

thank you very much, i will try to adapt that solution to my code.
