Hey Guys!
Need some help with a python script.
I want to control my Denon AV Receiver with a buttons device. The Denon can be controlled via commands over Telnet. For that I have found a script, that does what it should.
But one thing I am wondering is, how I can use this script as a commandline tool?
Am not firm with coding, therefore need your help! Is this possible?
The script is working fine when calling x.vol_up() or x.vol_down() directly - see bottom of the script. But how can i call the functions directly from the commandline like python denon vol_up or python denon vol_down for example.
The advantage would be, that there’s only one script doing the work and not creating a separate script for each function Is there an easy way?
here’s the code, the file is called denon
import socket
import string
from time import sleep
import re
LIMIT=135
class Avr:
def __init__(self, addr, port = 23):
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sock.connect((addr, port))
self.buf=[]
def command(self, message):
self.sock.send(message + '\r')
def response(self):
if len(self.buf) < 2:
data=self.sock.recv(LIMIT)
n = string.split(data, '\r')
if len(self.buf) == 1:
n[0] = self.buf[0] + n[0]
self.buf = n
return self.buf.pop(0).strip()
def close(self):
self.sock.close()
# *** volume & mute *********
def vol_up(self):
self.command("MVUP")
def vol_down(self):
self.command("MVDOWN")
def vol_query(self):
self.command("MV?")
return self.response()
def mute(self):
self.command("MUON");
def unmute(self):
self.command("MUOFF");
def is_muted(self):
self.command("MU?")
return self.response() != "MUOFF"
# *** input ***
def select_dvr(self):
self.command("SIDVR")
def select_rhapsody(self):
self.command("SIRHAPSODY")
def select_hdp(self):
self.command("SIHDP")
def select_server(self):
self.command("SIHDP")
def source(self):
self.command("SI?")
return self.response()
# *** net screen ***
def onscreen_display(self):
self.command("NSE")
ret = []
for line in range(9):
n = self.response()
n = n[4:-1]
if line != 0 and line != 8:
# tag = n[0]
n = n[1:-1]
ret.append( n )
return string.join(ret, '\n')
x = Avr("192.168.178.67")
#x.select_rhapsody()
#print x.source()
#print x.onscreen_display()
x.vol_up()
#x.vol_down()
#x.mute()
sleep(2)
x.close()
