pydle is a compact, flexible and standards-abiding IRC library for Python 3.5+.
pip install pydle
From there, you can
import pydle and subclass
pydle.Client for your own functionality.
Setting a nickname and starting a connection over TLS:
import pydle # Simple echo bot. class MyOwnBot(pydle.Client): async def on_connect(self): await self.join('#bottest') async def on_message(self, target, source, message): # don't respond to our own messages, as this leads to a positive feedback loop if source != self.nickname: await self.message(target, message) client = MyOwnBot('MyBot', realname='My Bot') client.run('irc.rizon.net', tls=True, tls_verify=False)
But wait, I want to handle multiple clients!
No worries! Use
pydle.ClientPool like such:
pool = pydle.ClientPool() for i in range(10): client = MyOwnBot('MyBot' + str(i)) pool.connect(client, 'irc.rizon.net', 6697, tls=True, tls_verify=False) # This will make sure all clients are treated in a fair way priority-wise. pool.handle_forever()
Furthermore, since pydle is simply
asyncio-based, you can run the client in your own event loop, like this:
import asyncio client = MyOwnBot('MyBot') loop = asyncio.get_event_loop() asyncio.ensure_future(client.connect('irc.rizon.net', tls=True, tls_verify=False), loop=loop) loop.run_forever()
If you want to customize bot features, you can subclass
pydle.BasicClient and one or more features from
pydle.features or your own feature classes, like such:
# Only support RFC1459 (+small features), CTCP and our own ACME extension to IRC. class MyFeaturedBot(pydle.features.ctcp.CTCPSupport, acme.ACMESupport, rfc1459.RFC1459Support): pass
To create your own features, just subclass from
pydle.BasicClient and start adding callbacks for IRC messages:
# Support custom ACME extension. class ACMESupport(pydle.BasicClient): async def on_raw_999(self, source, params): """ ACME's custom 999 numeric tells us to change our nickname. """ nickname = params await self.set_nickname(nickname)
Q: When constructing my own client class from several base classes, I get the following error: TypeError: Cannot create a consistent method resolution order (MRO) for bases X, Y, Z. What causes this and how can I solve it?
Pydle's use of class inheritance as a feature model may cause method resolution order conflicts if a feature inherits from a different feature, while a class inherits from both the original feature and the inheriting feature. To solve such problem, pydle offers a
featurize function that will automatically put all classes in the right order and create an appropriate base class:
# Purposely mis-ordered base classes, as SASLSupport inherits from CapabilityNegotiationSupport, but everything works fine. MyBase = pydle.featurize(pydle.features.CapabilityNegotiationSupport, pydle.features.SASLSupport) class Client(MyBase): pass
Q: How do I...?
Stop! Read the documentation first. If you're still in need of support, join us on IRC! We hang at
irc.libera.chat. If someone is around, they'll most likely gladly help you.
