Known Subclasses:
  `IRCProto`, `TendrilIRC`

Internet Relay Chat client protocol, with sprinkles.

In addition to providing an interface for an IRC client protocol, this class also contains reasonable implementations of many common CTCP methods.

# TODO

- Limit the length of messages sent (because the IRC server probably does).
- Add flood protection/rate limiting for my CTCP replies.
- NickServ cooperation. (a mix-in?)
- Heartbeat. The transport may die in such a way that it does not realize it is dead until it is written to. Sending something (like "PING this.irc-host.net") during idle peroids would alleviate that. If you're concerned with the stability of the host as well as that of the transport, you might care to watch for the corresponding PONG.

Method Details

### action(self, user, channel, data) Called when I see a user perform an ACTION on a channel.

### badMessage(self, line, excType, excValue, tb) When I get a message that's so broken I can't use it.

### connectionMade(self) Called when a connection is made. This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here. Overrides: `twisted.internet.protocol.BaseProtocol.connectionMade` (inherited documentation)

### ctcpMakeQuery(self, user, messages) Send one or more extended messages as a CTCP query. Parameters: `messages` (type=a list of extended messages. An extended message is a (tag, data) tuple, where 'data' may be `None`.)

### ctcpMakeReply(self, user, messages) Send one or more extended messages as a CTCP reply. Parameters: `messages` (type=a list of extended messages. An extended message is a (tag, data) tuple, where 'data' may be `None`.)

### ctcpQuery(self, user, channel, messages) Dispatch method for any CTCP queries received.

### ctcpQuery_CLIENTINFO(self, user, channel, data) A master index of what CTCP tags this client knows. If no arguments are provided, respond with a list of known tags. If an argument is provided, provide human-readable help on the usage of that tag.

### ctcpQuery_DCC(self, user, channel, data) Initiate a Direct Client Connection

### ctcpReply(self, user, channel, messages) Dispatch method for any CTCP replies received.

### ctcpUnknownReply(self, user, channel, tag, data) Called when a fitting ctcpReply_ method is not found. XXX: If the client makes arbitrary CTCP queries, this method should probably show the responses to them instead of treating them as anomolies.

### dataReceived(self, data) Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.) Overrides: `twisted.protocols.basic.LineReceiver.dataReceived` (inherited documentation)

### dccAcceptResume(self, user, fileName, port, resumePos) Send a DCC ACCEPT response to clients who have requested a resume.

### dccDoAcceptResume(self, user, file, port, resumePos) Called when a client has verified and accepted a DCC resume request made by us. By default it will do nothing.

### dccDoResume(self, user, file, port, resumePos) Called when a client is trying to resume an offered file via DCC send. It should be either replied to with a DCC ACCEPT or ignored (default).

### dccDoSend(self, user, address, port, fileName, size, data) Called when I receive a DCC SEND offer from a client. By default, I do nothing here.

### dccResume(self, user, fileName, port, resumePos) Send a DCC RESUME request to another user.

### handleCommand(self, command, prefix, params) Determine the function to call for the given command and call it with the given arguments.

### irc_KICK(self, prefix, params) Kicked? Who? Not me, I hope.

### irc_RPL_TOPIC(self, prefix, params) I just joined the channel, and the server is telling me the current topic.

### irc_TOPIC(self, prefix, params) Someone in the channel set the topic.

### joined(self, channel) Called when I finish joining a channel. channel has the starting character (# or &) intact.

### kickedFrom(self, channel, kicker, message) Called when I am kicked from a channel.

### left(self, channel) Called when I have left a channel. channel has the starting character (# or &) intact.

### lineReceived(self, line) Override this for when each line is received. Overrides: `twisted.protocols.basic.LineReceiver.lineReceived` (inherited documentation)

### me(self, channel, action) Strike a pose.

### mode(self, chan, set, modes, limit=None, user=None, mask=None) Change the modes on a user or channel.

### modeChanged(self, user, channel, set, modes, args) Called when a channel's modes are changed Parameters: `user` - The user and hostmask which instigated this change. (type=`str`) `channel` - The channel for which the modes are changing. (type=`str`) `set` - true if the mode is being added, false if it is being removed. (type=`bool` or `int`) `modes` - The mode or modes which are being changed. (type=`str`) `args` - Any additional information required for the mode change. (type=`tuple`)

### nickChanged(self, nick) Called when my nick has been changed.

### noticed(self, user, channel, message) Called when I have a notice from a user to me or a channel. By default, this is equivalent to IRCClient.privmsg, but if your client makes any automated replies, you must override this! From the RFC:
       The difference between NOTICE and PRIVMSG is that
       automatic replies MUST NEVER be sent in response to a
       NOTICE message. [...] The object of this rule is to avoid
       loops between clients automatically sending something in
       response to something it received.

### ping(self, user, text=None) Measure round-trip delay to another IRC client.

### pong(self, user, secs) Called with the results of a CTCP PING query.

### privmsg(self, user, channel, message) Called when I have a message from a user to me or a channel.

### quirkyMessage(self, s) This is called when I receive a message which is peculiar, but not wholly indecipherable.

### receivedMOTD(self, motd) I received a message-of-the-day banner from the server. motd is a list of strings, where each string was sent as a seperate message from the server. To display, you might want to use:
       string.join(motd, '\n')
to get a nicely formatted string.

### sendLine(self, line) Sends a line to the other end of the connection. Overrides: `twisted.protocols.basic.LineReceiver.sendLine` (inherited documentation)

### signedOn(self) Called after sucessfully signing on to the server.

### topic(self, channel, topic=None) Attempt to set the topic of the given channel, or ask what it is. If topic is None, then I sent a topic query instead of trying to set the topic. The server should respond with a TOPIC message containing the current topic of the given channel.

### topicUpdated(self, user, channel, newTopic) In channel, user changed the topic to newTopic. Also called when first joining a channel.

### userJoined(self, user, channel) Called when I see another user joining a channel.

### userKicked(self, kickee, channel, kicker, message) Called when I observe someone else being kicked from a channel.

### userLeft(self, user, channel) Called when I see another user leaving a channel.

### userRenamed(self, oldname, newname) A user changed their name from oldname to newname.
