Event Reference

Table of Contents


The module offers named, numeric, and convenience events. The named and numeric events correspond to IRC protocol events, while convenience events are an extra layer provided to make using the module easier. This means one IRC event can trigger several events of the module. For example, if someone addresses our bot in a channel, the following chain of events will be fired:

irc-addressed  ▶  irc-to-me  ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all

The events are ordered from "narrowest" to "widest": irc-addressed can be triggered only in-channel, when our bot is addressed; irc-to-me can also be triggered via notice and private message, so it's wider; irc-privmsg-channel includes all channel messages, so it's wider still; and irc-privmsg also includes private messages to our bot. The chain ends by the widest event of them all: irc-all.

Responding to Events

See section in Basic Tutorial for responding by returning a value from the event handler.

The Message Objects received by the event handlers for the irc-privmsg and irc-notice event chains also provide a .reply method using which you can reply to the event. When this method is called .is-replied attribute of the Message Object is set to True, which signals to the Client Object that the returned value from the event handler should be discarded.

Event Map

In the chart below, irc-nXXX stands for numeric events where XXX is a three-digit number. See this numerics table for meaning of codes, depending on the server used.

irc-addressed  ▶  irc-to-me      ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
                  irc-mentioned  ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
                                    irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
                  irc-to-me      ▶  irc-privmsg-me       ▶  irc-privmsg  ▶  irc-all

                                    irc-mode-me          ▶  irc-mode     ▶  irc-all

                  irc-connected  ▶  irc-nXXX              ▶  irc-numeric  ▶  irc-all
                                    irc-nXXX              ▶  irc-numeric  ▶  irc-all
                                                            irc-join     ▶  irc-all
                                                            irc-nick     ▶  irc-all
                                                            irc-part     ▶  irc-all
                                                            irc-quit     ▶  irc-all
                                                            irc-unknown  ▶  irc-all

                                                                            irc-started

Note: irc-started is a special event that's exempt from the rules applicable to all other events and their event handlers:

  • It's called just once per call of IRC::Client's .run method, regardless of how many times the client reconnects
  • When it's called, there's no guarantee the connections to servers have been fully established yet or channels joined yet.
  • Unless all other event handlers, this one does not take any arguments
  • Return values from handlers are ignored and the event is propagated to all of the plugins
  • This event does not trigger irc-all event

Event Triggers

irc-addressed

irc-addressed  ▶  irc-to-me  ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
irc-addressed  ▶  irc-to-me  ▶  irc-notice-channel   ▶  irc-notice   ▶  irc-all

This event chain is triggered when the client is addressed in a channel either via a PRIVMSG or NOTICE IRC message. 'Addressed' means the message line starts with the current nickname of the client or one of its aliases, followed by ; or , characters, followed by any number of whitespace; or in regex terms, matches /^ [$nick | @aliases] <[,:]> \s* /. This prefix portion will be stripped from the actual message.

Possible message objects received by event handler:

  • IRC::Client::Message::Privmsg::Channel
  • IRC::Client::Message::Notice::Channel

irc-all

irc-all

Triggered on all events, except for the special irc-started event.

Possible message objects received by event handler:

  • IRC::Client::Message::Notice::Channel
  • IRC::Client::Message::Notice::Me

irc-connected

irc-connected  ▶  irc-n001  ▶  irc-numeric  ▶  irc-all

Triggered on 001 numeric IRC command that indicates we successfully connected to the IRC server and obtained a nickname. Note: it's not guaranteed that we already joined all the channels when this event is triggered; in fact, it's more likely that we haven't yet. Also note: that in long running programs this event will be triggered more than once, because the client automatically reconnects when connection drops, so the event will be triggered on each reconnect. See also irc-started

Receives IRC::Client::Message::Numeric message object.

irc-join

irc-join  ▶  irc-all

Triggered when someone joins a channel we are in. Note: typically the server will generate this event when we join a channel too. Receives IRC::Client::Message::Join message object.

irc-mentioned

irc-mentioned  ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
irc-mentioned  ▶  irc-notice-channel   ▶  irc-notice   ▶  irc-all

This event chain is triggered when the client is mentioned in a channel either via a PRIVMSG or NOTICE IRC message. Being mentioned means the message contains our nick or one of the aliases delimited by word boundaries on both sides; or in regex terms, matches / << [$nick | @aliases] >> /.

Possible message objects received by event handler:

  • IRC::Client::Message::Privmsg::Channel
  • IRC::Client::Message::Notice::Channel

irc-mode

  • IRC::Client::Message::Mode::Channel
  • IRC::Client::Message::Mode::Me

irc-mode-channel

irc-mode-channel  ▶  irc-mode  ▶  irc-all

irc-nick  ▶  irc-all

Triggered when someone in a channel we are in changes nick. Note: typically the server will generate this event when we change a nick too. Receives IRC::Client::Message::Nick message object.

irc-notice

irc-notice  ▶  irc-all

Triggered on NOTICE messages sent to a channel the client is in or to the client directly.

Possible message objects received by event handler:

  • IRC::Client::Message::Notice::Channel
  • IRC::Client::Message::Notice::Me

irc-notice-channel

irc-notice-channel  ▶  irc-notice  ▶  irc-all

Triggered on NOTICE messages sent to a channel the client is in. Receives IRC::Client::Message::Notice::Channel message object.

irc-notice-me

irc-notice-me  ▶  irc-notice  ▶  irc-all

Triggered on NOTICE messages sent directly to the client. Receives IRC::Client::Message::Notice::Me message object.

irc-numeric

irc-numeric  ▶  irc-nXXX  ▶  irc-all

Possible message objects received by event handler:

  • IRC::Client::Message::Privmsg::Channel
  • IRC::Client::Message::Privmsg::Me

irc-privmsg-channel

irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all

irc-quit  ▶  irc-all

Triggered when someone in a channel we are in quits IRC. Receives IRC::Client::Message::Quit message object.

irc-started

irc-started

The event is different from all others (see end of Event Map section). It's triggered just once per call of .run method on IRC::Client object, regardless of how many times the client reconnects, and it's called on all of the plugins, regardless of the return value of the event handler.

Does not receive any arguments.

irc-to-me

irc-addressed  ▶  irc-to-me  ▶  irc-privmsg-channel  ▶  irc-privmsg  ▶  irc-all
                  irc-to-me  ▶  irc-privmsg-me       ▶  irc-privmsg  ▶  irc-all

irc-addressed  ▶  irc-to-me  ▶  irc-notice-channel   ▶  irc-notice   ▶  irc-all
                  irc-to-me  ▶  irc-notice-me        ▶  irc-notice   ▶  irc-all

This event chain is triggered when the client is addressed in a channel via a PRIVMSG or NOTICE IRC message or receives a private or notice message directly. In cases where the trigger happened due to being addressed in channel, the prefix used for addressing (nick|aliases + , or . + whitespace) will be stripped from the message.

Possible message objects received by event handler:

  • IRC::Client::Message::Privmsg::Channel
  • IRC::Client::Message::Privmsg::Me
  • IRC::Client::Message::Notice::Channel
  • IRC::Client::Message::Notice::Me

Note irrelevant to common users: to avoid spurious triggers during IRC server connection negotiation, this event does not fire until the server deems the client connected; that is, sends the IRC 001 command.

irc-unknown

irc-unknown  ▶  irc-all

Triggered when an unknown event is generated. You're not supposed to receive any of these and receiving one likely indicates a problem with IRC::Client. Please report this on the Issue tracker, indicating what server generated such a message and include your code too, if possible.

Receives IRC::Client::Message::Unknown message object.

irc-nXXX

Note:* XXX stands for a three-digit numeric code of the command that triggered the event, for example irc-n001. See irc-numeric for event trigger that responds to all numerics.

irc-nXXX  ▶  irc-numeric  ▶  irc-all

Triggered on numeric IRC commands. Receives IRC::Client::Message::Numeric message object.
