Protocol::IRC::Message- encapsulates a single IRC message
use Protocol::IRC::Message; my $hello = Protocol::IRC::Message->new( "PRIVMSG", undef, "World", "Hello, world!" ); printf "The command is %s and the final argument is %s\n", $hello->command, $hello->arg( -1 );
An object in this class represents a single IRC message, either received from or to be sent to the server. These objects are immutable once constructed, but provide a variety of methods to access the contained information.
This class also understands IRCv3 message tags.
$message = Protocol::IRC::Message->new_from_line( $line )
Returns a new
Protocol::IRC::Messageobject, constructed by parsing the given IRC line. Most typically used to create a new object to represent a message received from the server.
$message = Protocol::IRC::Message->new( $command, $prefix, @args )
Returns a new
Protocol::IRC::Messageobject, intialised from the given components. Most typically used to create a new object to send to the server using
stream_to_line. The message will contain no IRCv3 tags.
$message = Protocol::IRC::Message->new_from_named_args( $command, %args )
Returns a new
Protocol::IRC::Messageobject, initialised from the given named arguments. The argument names must match those required by the given command.
$mesage = Protocol::IRC::Message->new_with_tags( $command, \%tags, $prefix, @args )
Returns a new
Protocol::IRC::Messageobject, as with
newbut also containing the given IRCv3 tags.
$str = $message->STRING $str = "$message"
Returns a string representing the message, suitable for use in a debugging message or similar. Note: This is not the same as the IRC wire form, to send to the IRC server; for that see
$command = $message->command
Returns the command name or numeric stored in the message object.
$name = $message->command_name
For named commands, returns the command name directly. For server numeric replies, returns the name of the numeric.
$tags = $message->tags
Returns a HASH reference containing IRCv3 message tags. This is a reference to the hash stored directly by the object itself, so the caller should be careful not to modify it.
$prefix = $message->prefix
Returns the line prefix stored in the object, or the empty string if one was not supplied.
( $nick, $ident, $host ) = $message->prefix_split
Splits the prefix into its nick, ident and host components. If the prefix contains only a hostname (such as the server name), the first two components will be returned as
$arg = $message->arg( $index )
Returns the argument at the given index. Uses normal perl array indexing, so negative indices work as expected.
@args = $message->args
Returns a list containing all the message arguments.
$line = $message->stream_to_line
Returns a string suitable for sending the message to the IRC server.
$names = $message->arg_names
Returns a HASH reference giving details on how to parse named arguments for the command given in this message.
This will be a hash whose keys give the names of the arguments, and the values of these keys indicate how that argument is derived from the simple positional arguments.
Normally this method is only called internally by the
named_argsmethod, but is documented here for the benefit of completeness, and in case extension modules wish to define parsing of new message types.
Each value should be one of the following:
The value is a string, the nickname given in the message prefix
The value is an ARRAY ref, containing a list of all the numbered arguments between the (inclusive) given limits. Either or both limits may be negative; they will count backwards from the end.
The value is the argument at that numeric index. May be negative to count backwards from the end.
The value is the argument at that numeric index as for
NUMBER, except that the result will be split on spaces and stored in an ARRAY ref.
$names = Protocol::IRC::Message->arg_names( $command )
This method may also be invoked as a class method by passing in the command name or numeric. This allows inspection of what arguments would be required or returned before a message object itself is constructed.
$args = $message->named_args
Parses arguments in the message according to the specification given by the
arg_namesmethod. Returns a hash of parsed arguments.
TODO: More complete documentation on the exact arg names/values per message type.
$disp = $message->gate_disposition
Returns the "gating disposition" of the message. This defines how a reply message from the server combines with other messages in response of a command sent by the client. The disposition is either
undef, or a string consisting of a type symbol and a gate name. If defined, the symbol defines what effect it has on the gate name.
Adds more information to the response for that gate, but doesn't yet complete it.
Completes the gate with a successful result.
Completes the gate with a successful result, but only if the nick in the message prefix relates to the connection it is received on.
Completes the gate with a failure result.
