pyrcb is a very simple library for Python IRC bots. It isn't a full implementation of IRC; it provides just enough to write IRC bots. pyrcb is compatible with both Python 2 and 3.
To use it, import pyrcb and create a class that inherits IrcBot. Override one or more of the events. (You will most likely want to call send() from within the events.) Create an instance of your class and call connect(), register(), optionally join(), and listen(). See example.py for an example.
IrcBot's constructor takes one optional argument, debug_print. Setting this value to True will cause all communication with the IRC server to be printed to standard output.
on_join(self, nickname, channel)
Called when a user joins a channel.
on_part(self, nickname, channel)
Called when a user leaves a channel.
on_quit(self, nickname)
Called when a user quits.
on_message(self, nickname, target, is_query)
Called when a message is received.
target is who/what the bot should reply to. If the message is in a channel, target is the channel. If the message is in a private query, target is the other user.
connect(hostname, port)
Connects to the specified hostname and port.
register(nickname)
Sends the IRC server nickname and user information.
join(channel)
Joins the specified channel.
part(channel)
Leaves the specified channel.
quit()
Closes connection to the IRC server.
send(target, message)
Sends target the specified message. target can be a channel or user.
listen()
Listens for incoming messages, calling events when appropriate. This method is blocking and returns when connection to the IRC server is lost.
listenOnce()
Similar to listen(), except it only listens once allows the user to run other actions in between. It returns right after checking for a message once.
