Functions that you can use in Irssi's Perl scripts
 --------------------------------------------------

This is just my very first implementation and things will probably change.

Commands marked with (!!) mean that you shouldn't use it unless you
know what you're doing..

If there's a "Xxxx::" text before the command, it means that it belongs to
that package. Like "Server::command" means that you should either call it as
  Irssi::Server::command($server, $cmd);
or more easily:
  $server->command($cmd);

Commands that don't have the Xxxx prefix are called as Irssi::command();

A list of signals that irssi send can be found from SIGNALS file.


 *** General

Channel cur_channel() - return current channel
Server cur_server() - return current server

channels() - return list of all channels
servers() - return list of all servers
commands() - return list of all commands
dccs() - return list of all dcc connections
logs() - return list of all log files
plugins() - return list of all plugins

print(str)
  Print `str' to current window as "Irssi notice".

command(cmd, [Server server, [Channel channel]])
  Send a command `cmd' (in current channel). This will work just as if you
  had typed `cmd' in command line, so you'll need to use /COMMANDS or the
  text will be sent to the channel.

Server::command(cmd, [Channel channel])
  Just like above, except different calling method.

Channel::command(cmd)
  Just like above, except different calling method.

Server::printtext(channel, level, str)
  Print `str'.


 *** Message levels

level2bits(level)
  Level string -> number

bits2level(bits)
  Level number -> string

combine_level(level, str)
  Combine level number to level string ("+level -level").
  Return new level number.


 *** Signals / timeouts

signal_emit(signal, ...)
  Send signal `signal'

signal_add(signal, func)
  Bind `signal' to function `func'

signal_remove(signal, func)
  Unbind `signal' from function `func'

tag timeout_add(msecs, func, data)
  Call `func' every `msecs' milliseconds (1000 = 1 second) with
  parameter `data'. Returns tag which can be used to stop the timeout.

timeout_remove(tag)
  Remove timeout with tag.


 *** Commands

Command::values()
  Get some information about command. This function returns a reference to
  hash table (FIXME: can't it return the hash table itself?!). Hash table
  has keys:
	"cmd" - Command
	"category" - Category

command_bind(cmd, category, func)
  Bind command `cmd' to call function `func'. `category' is the
  category where the command is displayed in /HELP.

command_unbind(cmd, func)
  Unbind command `cmd' from function 'func.

Server::command_split(cmd, arg, max_nicks)
  Split the `cmd' into several commands so `arg' argument has only
  `max_nicks' number of nicks.

  Example: $server->command_split("KICK nick1,nick2,nick3 :byebye", 1, 2);
  Irssi will send commands "KICK nick1,nick2 :byebye" and
  "KICK nick3 :byebye" to server.


 *** Server functions

Server::values()
  Get some information about server. This function returns a reference to
  hash table (FIXME: can't it return the hash table itself?!). Hash table
  has keys:
	"address" - Address where we connected (irc.blah.org)
	"real_address" - Who the server thinks it is (irc1.blah.org)
	"port" - Port where we connected
	"tag" - Unique server tag.
	"ircnet" - IRC network
	"password" - Password we used in connection.

	"nick" - Current nick
	"wanted_nick" - Nick which we would prefer to use
	"username" - User name
	"realname" - Real name
	"usermode" - Current user mode
	"connected" - Is connection finished? 1|0
	"connection_lost" - Did we lose the connection (1) or was
	                    the connection meant to be disconnected (0)
  Example:
	%server_info = %{Irssi::cur_server->values()};
	Irssi::print("Current server = ".$server_info{'address'});

Server server_connect(address, [port=6667, [password='', [nick='']]])
  Create new server connection.

Server::disconnect()
  Disconnect from server.

Server server_find_tag(tag)
  Find server with tag

Server server_find_ircnet(ircnet)
  Find first server that is in `ircnet'

Channel channel_find_any(channel)
  Find `channel' from any server

Server::send_raw(cmd)
  Send raw message to server, it will be flood protected so you
  don't need to worry about it.

Server::ctcp_send_reply(data)
  Send CTCP reply. This will be "CTCP flood protected" so if there's too
  many CTCP requests in buffer, this reply might not get sent.


 *** Server redirections

WARNING: It's easy to mess up the Irssi's internal server expectations with
these commands!

This is a powerful feature of Irssi that I can't seen in other IRC clients.
You can EASILY grab the server's reply for a command you send to server
without any horrible kludges.

Server::redirect_init(command, last, ...)
  Initialize redirection for specified command. This needs to be done only
  once. Irssi already initializes commands "WHOIS", "WHO", "LIST" and "ISON".
  `command' is the whole name of the signal, like "command whois".
  `last' specifies how many of the items in `...' is considered as the
  "last event" from the command.

  Example: $server->redirection_init('command who',
        2, # 2 first events will finish the command
	'event 401', # unknown nick (finished)
	'event 315', # end of who (finished)
	'event 352'); # who line (wait..)

Server::redirect_event(arg, last, ...)
  Add redirection. `arg' is a space separated list of arguments that should
  match before Irssi will redirect the event (think of /WHOIS nick nick and
  doing another to different nick immediately after it, there's no way of
  knowing which will return first. so, arg would be in this case 'nick').

  `last' specifies how many of the following events are considered as
  "last event" from command - just like in redirect_init().

  `...' is `event, signal, argpos, ...`, where
  `event' is the event we're waiting from server.
  `signal' is the signal we will send after receiving the event. It should
           always start with 'redir ' so that Irssi's perl handler knows to
	   send correct arguments to signal handler.
  `argpos' is the argument position in event's data or -1 if it
           should be ignored.

  Example:
	$server->send_raw('WHOIS :cras');
	$server->redirect_event('cras', 2,
			  "event 318", "redir end_of_whois", -1,
			  "event 402", "redir no_such_server", -1,
			  "event 401", "redir no_such_nick", 1,
			  "event 311", "redir whois", 1,
			  "event 301", "redir whois_away", 1,
			  "event 312", "redir whois_server", 1,
			  "event 313", "redir whois_oper", 1,
			  "event 317", "redir whois_idle", 1,
			  "event 319", "redir whois_channels", 1);
  In the 402-case we tried "/WHOIS nick nick" but nick didn't exist..

group Server::redirect_single_event(arg, last, group, event, signal, argpos)
  Same as redirect_event() except you can set it up in pieces.
  If `group' is 0, it will create new group and return it's id.


 *** IRC masks
