Usage (Detailed Usage)

from Packet import Packet, ref
import sys, socket, select, time

class opcodes:
    LOGIN=100
    LOGOUT=101

HOST, PORT = "127.0.0.1", 2000

CLIENT

Paket = Packet(opcodes.LOGIN, Encrypt=True, Compress=True)
Username = "Emre"
Paket << Username << "123" << True << bytearray(b'\x07\x10BYTES\xFF') << ["Apple", "Banana", "Orange"]
Paket.Send(socket)

SERVER

# Listener Thread
PaketListen = Packet()
while True:
    if PaketListen.Recv(socketServer):
        PaketListen.Print("RECEIVED PACKET (YOUR TITLE)!")
        if PacketListen.GetOpcode() == opcodes.LOGIN:
            UserName, Password, RememberMe, Data, Fruits = ref(str), ref(str), ref(bool), ref(bytearray), ref(list)
            PacketListen >> UserName >> Password >> RememberMe >> Data >> Fruits
            UserName, Password, RememberMe, Data, Fruits = str(UserName), str(Password), RememberMe.obj, bytearray(Data.obj), ", ".join(Fruits.obj)  # We have to cast ref object to (int, str, bool, bytearray ...)
            # Note: Can't use bool(RememberMe), this returns True everytime. Use .obj always !!!

            print(f"Username: {UserName}\nPassword: {Password}\nRememberMe: {'Yes' if RememberMe else 'No'}\nData: {str(Data)}\nFruits: {Fruits}")
    else:
        return # Connection Lost
