ircstates

rationale

I wanted a bare-bones reference implementation of taking byte input, parsing it into tokens and then managing an IRC client session state from it.

with this library, you can have client session state managed for you and put additional arbitrary functionality on top of it.

usage

socket to state

import ircstates, irctokens, socket

NICK = "nickname"
CHAN = "#chan"
HOST = "127.0.0.1"
POST = 6667

server  = ircstates.Server("freenode")
sock    = socket.socket()
encoder = irctokens.StatefulEncoder()

sock.connect((HOST, POST))

def _send(raw):
    tokens = irctokens.tokenise(raw)
    encoder.push(tokens)

_send("USER test 0 * test")
_send(f"NICK {NICK}")

while True:
    while encoder.pending():
        sent_lines = encoder.pop(sock.send(encoder.pending()))
        for line in sent_lines:
            print(f"> {line.format()}")

    recv_lines = server.recv(sock.recv(1024))
    for line in recv_lines:
        print(f"< {line.format()}")

        # user defined behaviors...
        if line.command == "PING":
            _send(f"PONG :{line.params[0]}")

        if line.command == "001" and not CHAN in server.channels:
            _send(f"JOIN {CHAN}")

get a user's channels

>>> server.users
{'nickname': User(nickname='nickname')}
>>> user = server.users["nickname"]
>>> user
User(nickname='nickname')
>>> server.user_channels[user]
{Channel(name='#chan')}

get a channel's users

>>> server.channels
{'#chan': Channel(name='#chan')}
>>> channel = server.channels["#chan"]
>>> channel
Channel(name='#chan')
>>> server.channel_users[channel]
{User(nickname='nickname'): ChannelUser(user='nickname', channel='#chan', modes='ov')}

get a user's modes in channel

>>> user = server.users["nickname"]
>>> channel = server.channels["#chan"]
>>> channel_user = server.channel_users[channel][user]
>>> channel_user
ChannelUser(user='nickname', channel='#chan', modes='ov')
>>> channel_user.modes
{'o', 'v'}
