/* Python support by Adam Langley (agl@linuxpower.org) */

/* Welcome to the all singing, all dancing <crash> python support

   currently this is as stable as an elephant balenced on a bobby pin...

   current objects:
     XChat
     Server
     Session
     Data

   The first thing a script MUST do is import XChat. All the interface stems from this module.
   To start the ball rolling set XChat.XChat() to some variable. This is your interface.

   XChat:
     get_servers: returns a tuple of server objects
     get_sessions: returns a tuple of session object
     get_current_session: returns a session object
     hook_command(name, func): hooks the command @name and each this it is run it calls @func passing (String name, XChat.Session session, String Tuple args)
     register(name, desc): sets the script's name and description
     hook_signal(name, func): hooks the signal @name (e.g. "XP_TE_UJOIN") and calls @func everytime that signal fires passing (String name, Int flags, XChat.Data Tuple args)
     info: returns a dict (see .keys())

   Server:
     send(data): writes @data raw to the server
     info: returns a dict (see .keys())
     set(host, port, nick): sets the server that the object acts on to the one matching @host, @port and @nick

   Session:
     print_text(text): Displays @text on the session
     handle_cmd(cmd): acts as if @cmd had been typed in, but without putting @cmd in the session history
     get_users: returns a dict in the form nick:(host, isop, isvoice) (just call it in interactive mode - you'll see what I mean)
     info: returns a dict (see .keys())
     set(host, port, nick, channel): sets the session the object refereres to, to the session matching @host, @port, @nick and @channel
     get_server: returns the server object of the session

   Data:
     get_string: returns a string from the data
     get_server: returns a server from the data
     get_session: returns a session from the data
     get_number: returns a int *of* the data


   That should be resonably basic, the only odd thing is the Data class. Why the hell is it there? Well when the python signal handler gets called it gets 5 void *'s and a char. The void *'s could point to anything, it changes from signal to signal. Rather than try to code in every signal's meta data (and make an ugly mess) it wraps the void *'s up into Data objects which are passed to your python signal handler in a tuple (3rd arg). It's then upto you what you do with the data. For example a possible signal handler for XP_INBOUND:

   def signalhandler(name, flags, args):
          session = args[0].get_session()
	  server = args[1].get_server()
	  message = args[2].get_string()

	  print "Message to " + session.info()['channel'] + " from " + server.info()['hostname'] + ": " + message

  It doesn't do a lot ;) but I hope you get the idea.

  The other wierd thing is the .set() calls to the Server and Session classes. Well XChat is free to kill a server or session struct anytime it likes. So if you keep a Server or Session object between calls then the actual object it acts on could be free()'ed. If you then call it XChat will go down harder than a 6 ton whale from 30,000 feet. So rather then keep the actual object just keep the host, port, nick (for the Server) and channel (Session only) and for each call do something like:

  sess = XChat.Session()
  try:
          sess.set (stored_host, stored_port, stored_nick, stored_channel)
  except LookupError:
          print "You Git! Give me back my session,  *NOW*!\n"

  you can get the data from:
    XChat.Sever.info()[x] with x = 'hostname', 'port' and 'nick'
    OR
    XChat.Session.info()[x] with x = 'servername', 'serverport', 'servernick' and 'channel'


    The function handlers follow this naming system:
      pysH_(E|D|S|)<function name>

      E = sess obj
      S = server obj
      D = data obj

      so a function to handle a session call of some_func() would be
      pysH_Esome_func
  Have fun!
