SleekXMPP

SleekXMPP is an MIT licensed XMPP library for Python 2.6/3.1+, and is featured in examples in XMPP: The Definitive Guide by Kevin Smith, Remko Tronçon, and Peter Saint-Andre. If you’ve arrived here from reading the Definitive Guide, please see the notes on updating the examples to the latest version of SleekXMPP.

SleekXMPP’s design goals and philosphy are:

Low number of dependencies

Installing and using SleekXMPP should be as simple as possible, without having to deal with long dependency chains.

As part of reducing the number of dependencies, some third party modules are included with SleekXMPP in the thirdparty directory. Imports from this module first try to import an existing installed version before loading the packaged version, when possible.

Every XEP as a plugin
Following Python’s “batteries included” approach, the goal is to provide support for all currently active XEPs (final and draft). Since adding XEP support is done through easy to create plugins, the hope is to also provide a solid base for implementing and creating experimental XEPs.
Rewarding to work with
As much as possible, SleekXMPP should allow things to “just work” using sensible defaults and appropriate abstractions. XML can be ugly to work with, but it doesn’t have to be that way.

Here’s your first SleekXMPP Bot:

import logging

from sleekxmpp import ClientXMPP
from sleekxmpp.exceptions import IqError, IqTimeout


class EchoBot(ClientXMPP):

    def __init__(self, jid, password):
        ClientXMPP.__init__(self, jid, password)

        self.add_event_handler("session_start", self.session_start)
        self.add_event_handler("message", self.message)

        # If you wanted more functionality, here's how to register plugins:
        # self.register_plugin('xep_0030') # Service Discovery
        # self.register_plugin('xep_0199') # XMPP Ping

        # Here's how to access plugins once you've registered them:
        # self['xep_0030'].add_feature('echo_demo')

        # If you are working with an OpenFire server, you will
        # need to use a different SSL version:
        # import ssl
        # self.ssl_version = ssl.PROTOCOL_SSLv3

    def session_start(self, event):
        self.send_presence()
        self.get_roster()

        # Most get_*/set_* methods from plugins use Iq stanzas, which
        # can generate IqError and IqTimeout exceptions
        #
        # try:
        #     self.get_roster()
        # except IqError as err:
        #     logging.error('There was an error getting the roster')
        #     logging.error(err.iq['error']['condition'])
        #     self.disconnect()
        # except IqTimeout:
        #     logging.error('Server is taking too long to respond')
        #     self.disconnect()

    def message(self, msg):
        if msg['type'] in ('chat', 'normal'):
            msg.reply("Thanks for sending\n%(body)s" % msg).send()


if __name__ == '__main__':
    # Ideally use optparse or argparse to get JID,
    # password, and log level.

    logging.basicConfig(level=logging.DEBUG,
                        format='%(levelname)-8s %(message)s')

    xmpp = EchoBot('somejid@example.com', 'use_getpass')
    xmpp.connect()
    xmpp.process(block=True)
