Question

I’m making an ICQ (and XMPP in prospect) bot for a service, which should send and receive messages from users.

I’m using Python and Twisted. I started from the official documentation’s example (this one: http://twistedmatrix.com/documents/current/words/examples/oscardemo.py)

So far I successfully receive and process messages from ICQ contacts. Now I need to send messages, but not in a respond to their message or some event. I need to send messages with Oscar (Twisted’s thing for ICQ messaging) from outside the class with event handlers. How do I do that?

I’d appreciate any help since I fail to google anything useful, there’s not so much about using Oscar out there.

When you connect

protocol.ClientCreator(reactor, OA, SN, PASS, icq=icqMode).connectTCP(*hostport)

add a Deferred, which will be called when the connection is done:

oscar_prot = None

def get_B_instance(b_instance):
    global oscar_prot
    oscar_prot = b_instance

d = Deferred()
d.addCallback(get_B_instance)

protocol.ClientCreator(reactor, OA, SN, PASS, deferred=d, icq=icqMode).connectTCP(*hostport)

In the get_B_instance function, you can keep the reference to the instance of the protocol class.

Then you can just call sendMessage on that instance.

oscar_prot.sendMessage(username, message)
