Net::Async::IRC::Protocol - send and receive IRC messages
Net::Async::IRC::Protocol
This subclass of IO::Async::Protocol::LineStream implements an established IRC connection that has already completed its inital login sequence and is ready to send and receive IRC messages. It handles base message sending and receiving, and implements ping timers.
Objects of this type would not normally be constructed directly. For IRC clients, see Net::Async::IRC which is a subclass of it. All the events, parameters, and methods documented below are relevant there.
The following events are invoked, either using subclass methods or CODE references in parameters:
CODE
Invoked on receipt of a valid IRC message. See MESSAGE HANDLING below.
MESSAGE HANDLING
Invoked on receipt of an invalid IRC message if parsing fails. $err is the error message text. If left unhandled, any parse error will result in the connection being immediataely closed, followed by the exception being re-thrown.
$err
Invoked if the peer fails to respond to a PING message within the given timeout.
PING
Invoked when the peer successfully sends a PONG reply response to a PING message. $lag is the response time in (fractional) seconds.
PONG
$lag
The following named parameters may be passed to new or configure:
new
configure
CODE references for event handlers.
Amount of quiet time, in seconds, after a message is received from the peer, until a PING will be sent to check it is still alive.
Timeout, in seconds, after sending a PING message, to wait for a PONG response.
If supplied, sets an encoding to use to encode outgoing messages and decode incoming messages.
Returns a new instance of a Net::Async::IRC::Protocol object. This object represents a IRC connection to a peer. As it is a subclass of IO::Async::Protocol::LineStream its constructor takes any arguments for that class, in addition to the parameters named below.
IO::Async::Protocol::LineStream
Returns true if a connection to the peer is established. Note that even after a successful connection, the connection may not yet logged in to. See also the is_loggedin method.
is_loggedin
Returns true if the full login sequence has been performed on the connection and it is ready to use.
Returns the current nick in use by the connection.
Returns the current nick in use by the connection, folded by casefold_name for convenience.
casefold_name
A message with a command of COMMAND will try handlers in following places:
COMMAND
A CODE ref in a parameter called on_message_COMMAND
on_message_COMMAND
$on_message_COMMAND->( $irc, $message, \%hints )
A method called on_message_COMMAND
$irc->on_message_COMMAND( $message, \%hints )
A CODE ref in a parameter called on_message
on_message
$on_message->( $irc, 'COMMAND', $message, \%hints )
A method called on_message
$irc->on_message( 'COMMAND', $message, \%hints )
Certain commands are handled internally by methods on the base Net::Async::IRC::Protocol class itself. These may cause other hints hash keys to be created, or to invoke other handler methods. These are documented below.
