Slixmpp is an elegant Python library for XMPP (aka Jabber, Google Talk, etc).
Slixmpp is an MIT licensed XMPP library for Python 3.4+. It is a fork of SleekXMPP.
Slixmpp’s goals is to only rewrite the core of the library (the low level socket handling, the timers, the events dispatching) in order to remove all threads.
Slixmpp can make use of cython to improve performance on critical modules. To do that, cython3 is necessary along with libidn headers. Otherwise, no compilation is needed. Building is done by running setup.py:
python3 setup.py build_ext --inplace
Documentation can be found both inline in the code, and as a Sphinx project in /docs. To generate the Sphinx documentation, follow the commands below. The HTML output will be in docs/_build/html:
cd docs make html open _build/html/index.html
To run the test suite for Slixmpp:
Projects using Slixmpp tend to follow a basic pattern for setting up client/component connections and configuration. Here is the gist of the boilerplate needed for a Slixmpp based project. See the documetation or examples directory for more detailed archetypes for Slixmpp projects:
import logging from slixmpp import ClientXMPP from slixmpp.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('email@example.com', 'use_getpass') xmpp.connect() xmpp.process(forever=True)
