Sample send IM script?

[Parand Darugar]

Hello,

I'm attempting to get a simple Python DBUS based example of a script
that starts a conversation working. I have one that responds to IMs,
but I can't seem to figure out the incantation to get it to initiate
the IMs.

Can anyone send a script in any language (C, Perl, Python, Tcl) that
starts a conversation, or point me to appropriate documentation? I've
tried a number of things based on the Perl howto
(http://developer.pidgin.im/doxygen/dev/html/perl-howto.html), but I
can't get it to go.

My particular scenario is:

- I'm logged in to account 'xxx' using nullclient
- I'd like to initiate a conversation with account 'someaccount'
- I'm using D-Bus with Python (but it could be any language)

I start nullclient and I'm able to interact with it using D-Bus.
Here's what I'm trying:

import dbus, dbus.glib, dbus.decorators, gobject
bus = dbus.SessionBus()
obj = bus.get_object("im.pidgin.purple.PurpleService",
"/im/pidgin/purple/PurpleObject")
purple = dbus.Interface(obj, "im.pidgin.purple.PurpleInterface")
name = 'someaccount'
protocol = 'prpl-yahoo'
ac = purple.PurpleAccountsFind(name, protocol)   # returns a non-zero value
conversation = purple.PurpleConversationNew(1, ac, name)  #
conversation returns 0
im = purple.PurpleConversationGetImData(conversation)  # im is also 0
purple.PurpleConvImSend(im, "hello there")

Do I need some sort of connection or something after I find the
account to make this go?

Much thanks,

Parand
