evennia.server.portal.irc

This connects to an IRC network/channel and launches an ‘bot’ onto it. The bot then pipes what is being said between the IRC channel and one or more Evennia channels.

class evennia.server.portal.irc.IRCBot

Bases: twisted.words.protocols.irc.IRCClient, evennia.server.session.Session

An IRC bot that tracks activity in a channel as well as sends text to it when prompted

lineRate = 1

nickname = None

logger = None

factory: Optional[twisted.internet.protocol.Factory] = None

channel = None

sourceURL = 'http://code.evennia.com'

signedOn()

This is called when we successfully connect to the network. We make sure to now register with the game as a full session.

disconnect(reason='')

Called by sessionhandler to disconnect this protocol.

Parameters

reason (str) – Motivation for the disconnect.

at_login()

privmsg(user, channel, msg)

Called when the connected channel receives a message.

Parameters

• user (str) – User name sending the message.

• channel (str) – Channel name seeing the message.

• msg (str) – The message arriving from channel.

action(user, channel, msg)

Called when an action is detected in channel.

Parameters

• user (str) – User name sending the message.

• channel (str) – Channel name seeing the message.

• msg (str) – The message arriving from channel.

get_nicklist()

Retrieve name list from the channel. The return is handled by the catch methods below.

irc_RPL_NAMREPLY(prefix, params)

“Handles IRC NAME request returns (nicklist)

irc_RPL_ENDOFNAMES(prefix, params)

Called when the nicklist has finished being returned.

pong(user, time)

Called with the return timing from a PING.

Parameters

• user (str) – Name of user

• time (float) – Ping time in secs.

data_in(text=None, **kwargs)

Data IRC -> Server.

Keyword Arguments

• text (str) – Ingoing text.

• kwargs (any) – Other data from protocol.

send_channel(*args, **kwargs)

Send channel text to IRC channel (visible to all). Note that we don’t handle the “text” send (it’s rerouted to send_default which does nothing) - this is because the IRC bot is a normal session and would otherwise report anything that happens to it to the IRC channel (such as it seeing server reload messages).

Parameters

text (str) – Outgoing text

send_privmsg(*args, **kwargs)

Send message only to specific user.

Parameters

text (str) – Outgoing text.

Keyword Arguments

user (str) – the nick to send privately to.

send_request_nicklist(*args, **kwargs)

Send a request for the channel nicklist. The return (handled by self.irc_RPL_ENDOFNAMES) will be sent back as a message with type **nicklist’.

send_ping(*args, **kwargs)

Send a ping. The return (handled by self.pong) will be sent back as a message of type ‘ping’.

send_reconnect(*args, **kwargs)

The server instructs us to rebuild the connection by force, probably because the client silently lost connection.

send_default(*args, **kwargs)

Ignore other types of sends.

class evennia.server.portal.irc.IRCBotFactory(sessionhandler, uid=None, botname=None, channel=None, network=None, port=None, ssl=None)

Bases: twisted.internet.protocol.ReconnectingClientFactory

Creates instances of IRCBot, connecting with a staggered increase in delay

initialDelay = 1

factor = 1.5

maxDelay = 60

__init__(sessionhandler, uid=None, botname=None, channel=None, network=None, port=None, ssl=None)

Storing some important protocol properties.

Parameters

sessionhandler (SessionHandler) – Reference to the main Sessionhandler.

Keyword Arguments

• uid (int) – Bot user id.

• botname (str) – Bot name (seen in IRC channel).

• channel (str) – IRC channel to connect to.

• network (str) – Network address to connect to.

• port (str) – Port of the network.

• ssl (bool) – Indicates SSL connection.

buildProtocol(addr)

Build the protocol and assign it some properties.

Parameters

addr (str) – Not used; using factory data.

startedConnecting(connector)

Tracks reconnections for debugging.

Parameters

connector (Connector) – Represents the connection.

clientConnectionFailed(connector, reason)

Called when Client failed to connect.

Parameters

• connector (Connection) – Represents the connection.

• reason (str) – The reason for the failure.

clientConnectionLost(connector, reason)

Called when Client loses connection.

Parameters

• connector (Connection) – Represents the connection.

• reason (str) – The reason for the failure.

reconnect()

Force a reconnection of the bot protocol. This requires de-registering the session and then reattaching a new one, otherwise you end up with an ever growing number of bot sessions.

start()

Connect session to sessionhandler.
