Description

This package provides low-level commands to deal with the IRC protocol (Internet Relay Chat) for immediate and interactive multi-cast communication.

::irc::config ?key? ?value?
Sets configuration ?key? to ?value?. The configuration keys currently defined are the boolean flags logger and debug. logger makes irc use the logger package for printing error. debug requires logger and prints extra debug output. If no ?key? or ?value? is given the current values are returned.
::irc::connection
The command creates a new object to deal with an IRC connection. Creating this IRC object does not automatically create the network connection. It returns a new irc namespace command which can be used to interact with the new IRC connection. NOTE: the old form of the connection command, which took a hostname and port as arguments, is deprecated. Use connect instead to specify this information.
::irc::connections
Returns a list of all the current connections that were created with connection

Per-Connection Commands

In the following list of available connection methods net represents a connection command as returned by ::irc::connection.

net registerevent event script
Registers a callback handler for the specific event. Events available are those described in RFC 1459 http://www.rfc-editor.org/rfc/rfc1459.t…. In addition, there are several other events defined. defaultcmd adds a command that is called if no other callback is present. EOF is called if the connection signals an End of File condition. The events defaultcmd, defaultnumeric, defaultevent, and EOF are required. script is executed in the connection namespace, which can take advantage of several commands (see Callback Commands below) to aid in the parsing of data.
net getevent event script
Returns the current handler for the event if one exists. Otherwise an empty string is returned.
net eventexists event script
Returns a boolean value indicating the existence of the event handler.
net connect hostname ?port?
This causes the socket to be established. ::irc::connection created the namespace and the commands to be used, but did not actually open the socket. This is done here. NOTE: the older form of ´connect' did not require the user to specify a hostname and port, which were specified with 'connection'. That form is deprecated.
net config ?key? ?value?
The same as ::irc::config but sets and gets options for the net connection only.
net log level message
If logger is turned on by config this will write a log message at level.
net logname
Returns the name of the logger instance if logger is turned on.
net connected
Returns a boolean value indicating if this connection is connected to a server.
net sockname
Returns a 3 element list consisting of the ip address, the hostname, and the port of the local end of the connection, if currently connected.
net peername
Returns a 3 element list consisting of the ip address, the hostname, and the port of the remote end of the connection, if currently connected.
net socket
Return the Tcl channel for the socket used by the connection.
net user username localhostname localdomainname userinfo
Sends USER command to server. username is the username you want to appear. localhostname is the host portion of your hostname, localdomainname is your domain name, and userinfo is a short description of who you are. The 2nd and 3rd arguments are normally ignored by the IRC server.
net nick nick
NICK command. nick is the nickname you wish to use for the particular connection.
net ping target
Send a CTCP PING to target.
net serverping
PING the server.
net join channel ?key?
channel is the IRC channel to join. IRC channels typically begin with a hashmark ("#") or ampersand ("&").
net part channel ?message?
Makes the client leave channel. Some networks may support the optional argument message
net quit ?message?
Instructs the IRC server to close the current connection. The package will use a generic default if no message was specified.
net privmsg target message
Sends message to target, which can be either a channel, or another user, in which case their nick is used.
net notice target message
Sends a notice with message message to target, which can be either a channel, or another user, in which case their nick is used.
net ctcp target message
Sends a CTCP of type message to target
net kick channel target ?message?
Kicks the user target from the channel channel with a message. The latter can be left out.
net mode target args
Sets the mode args on the target target. target may be a channel, a channel user, or yourself.
net topic channel message
Sets the topic on channel to message specifying an empty string will remove the topic.
net invite channel target
Invites target to join the channel channel
net send text
Sends text to the IRC server.
net destroy
Deletes the connection and its associated namespace and information.

Callback Commands

These commands can be used within callbacks

who ?address?
Returns the nick of the user who performed a command. The optional keyword address causes the command to return the user in the format "username@address".
action
Returns the action performed, such as KICK, PRIVMSG, MODE, etc... Normally not useful, as callbacks are bound to a particular event.
target
Returns the target of a particular command, such as the channel or user to whom a PRIVMSG is sent.
additional
Returns a list of any additional arguments after the target.
header
Returns the entire event header (everything up to the :) as a proper list.
msg
Returns the message portion of the command (the part after the :).
