###SETUP###
# Edit These options as you need
botnick = 'botnick'      	            # Nickname of the bot
server = "irc.network.net" 	            # Server to connect to
channels = ["#channel1","#channel2"]        # List of channels to join once connected
port = 6667 			            # Port used to connect with
prefix = "-"                                # Prefix to determine what is a command

# IRC socket setup
ircsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 

###FUNCTIONS###

def ping():
    ircsock.send("PONG :Pong\n")
  
def triggure(nick,channel,message):
    if message[-2:]==":y":
        pie(channel)
    elif message.find(":"+prefix)!=-1:
        command = message.split(":"+prefix)[1]
        commands(nick,channel,message,command)

def pie(channel):
    sendmsg(channel , "Here is some pie")
    
def sendmsg(channel , msg):
    ircsock.send("PRIVMSG "+ channel +" :"+ msg +"\n")
  
def joinchan(channel):
    ircsock.send("JOIN "+ channel +"\n")

def commands(nick,channel,message,command):
    if command.find("join")!=-1:
        print(command.split("join ")[1])
        joinchan(command.split("join ")[1])

###IRC LOGIN###
# initial login to IRC
ircsock.connect((server, port)) 
ircsock.send("USER "+ botnick +" "+ botnick +" "+ botnick +" :Hey\n") 
ircsock.send("NICK "+ botnick +"\n")
for i in channels:
    joinchan(i) 


###CONNECTION LOOP###
# Once connected it continues to search for a message
while 1:
  ircmsg = ircsock.recv(2048) 
  ircmsg = ircmsg.strip('\n\r') 
  print(ircmsg)
  if ircmsg.find(' PRIVMSG ')!=-1:
    nick=ircmsg.split('!')[0][1:]
    channel=ircmsg.split(' PRIVMSG ')[-1].split(' :')[0]
    try: 
      triggure(nick,channel,ircmsg)
    except:
      pass 
  if ircmsg.find("PING :") != -1: 
    ping()
