pydle is a compact, flexible and standards-abiding IRC library for Python 3.5+.
- Well-organized: Thanks to the modularized feature system, it's not hard to find what you're looking for in the well-organised source code.
- Standards-abiding: Based on RFC1459 with some small extension tweaks, with full support of optional extension standards:
- Asynchronous: IRC is an asynchronous protocol and so should be a library that implements it. Coroutines are used to process events from the server asynchronously.
- Modularised and extensible: Features on top of RFC1459 are implemented as separate modules for a user to pick and choose, and write their own. Broad features are written to be as extensible as possible.
- Liberally licensed: The 3-clause BSD license ensures you can use it everywhere.
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[0]
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 #pydle
on irc.libera.chat
. If someone is around, they'll most likely gladly help you.
