The work around is the work with the samples provided from Eiffel, it works as longest the two persons are connected in the same network. for example as follow:
Here we define if the user has receive the message or is waiting for one, also redefine the poll_command to be able to use it.
inherit
POLL_COMMAND
redefine
make
end
create
make
feature {NONE} -- Initialization
make (s: IO_MEDIUM)
do
Precursor (s)
create client_name.make_empty
end
feature
is_waiting: BOOLEAN
client_name: STRING
execute (arg: ANY)
do
is_waiting := True
end
initialize
do
is_waiting := False
end
set_client_name (s: STRING)
require
s_exists: s /= Void
do
client_name := s.twin
end
end
Then following the chat sample, that can be found in the samples folder, in the message handler, we create the follow:
set_client_name (s: STRING)
require
s_not_void: s /= Void
do
client_name := s.twin
end
set_new (flag: BOOLEAN)
do
new := flag
end
Later in the connection class we are able to connect to a server ip, which it can be pass true command line or via GUI input.
make_join (name: STRING; ip: STRING; gc: RG_CLIENT)
require
is_ip_void: ip /= Void
do
-- Connects to IP on port 1337
make (1337, ip)
max_to_poll := in_out.descriptor + 1
create connection.make (in_out)
create poll.make_read_only
poll.put_read_command (connection)
-- Sets client name and refrence
client_name := name
p_client := gc
-- Sends name to server and receives ID
client_id := send_name_to_server
-- Launches instance as thread
make_thread
launch
execute
end
Then in the server class...
make_server (gs: RG_SERVER)
local
l_message_out: detachable like message_out
l_connections: detachable like connections
l_in: detachable like in
do
-- Instantiate reference and create server listening on port 1337
game_server := gs
make (1337)
max_to_poll := 1
create poll.make_read_only
in.set_non_blocking
l_in := in
create l_connections.make
connections := l_connections
connections.compare_objects
-- Launches instance as tread
make_thread
launch
end
There is a bit more code, but this is a good sample in how to do it, there must be a method to handle the connections, but this is a good start, also remember that all this is based on their samples, chat sample is a good point of start..
enjoy eiffel while is not crashing .
