./IRCserver.py [HOST PORT [OPTIONS]] | -z [OPTIONS]

Create a server listening on HOST at PORT, and run it as a server which accepts client on it and broadcast every message from on client to all the other clients.

Options:

• –interactive, -i, -z, –zenity Force Zenity interactivity : read args HOST and PORT interactively,

  with Zenity and PyZenity (don’t use it unless you are sure to have both).

• -ni, --non-interactive
  	Disable Zenity interactivity : read args HOST and PORT from command line, Default.

• -h,–help Print this help message.

• -a	Print all message incomming from the client or outcomming to the server with verbous information.

• –debug Launch program in debug mod with pygdb.

Turn on the support of ANSI Colors. Can be used other somewhere else, or on other modules, AFTER importing ANSIColors module !

IRCserver.exit_with_Zenity(msg_erreur)

IRCserver.PRINT_ALL_MESSAGE = 1

1 to print messages

IRCserver.LISTEN_NB_CST = 16

Nb of input socket authorized (a max)

IRCserver.create_bind_socket(server=('127.0.0.1', 2048))

Create a socket and bind it to the port @port and the addresse @host.

IRCserver.create_data_socket(listen_socket, NB_CLIENT=0)

Create a data socket from the socket @listen_socket.

IRCserver.WRAPPER_OUT = '$:OUT: '

Piece of text to be printed before each output.

IRCserver.WRAPPER_IN = ':IN:$ '

Piece of text to be printed before each input.

IRCserver.broadcast_message_list(message='No message was gave', list_client=[], origin='UNKNOW', PRINT_ALL_MESSAGE=1)

IRCserver.action_on_readstr(readstr)

Reaction to special message readed from the keyboard !

IRCserver.irc_server(server=('127.0.0.1', 2048), PRINT_ALL_MESSAGE=1)

Create a server with addr,port=@server, listening on HOST at PORT,

and run it as a server which accepts client on it and broadcast every message from on client to all the other clients. Returns the socket_server when all connections are closed or the server decides to close himself.

Attention : to be respectuous of TCP conventions, if the connection is closed from the server stdin (Ctrl + C), the returned socket has to be closed by the programmer.

DEBUG, PRINT_ALL_MESSAGE: are options for parametrize behaviour of client.
