Re: LMS-CLI: telnet - "playlist index +1" does not work

To whomever is interested in my fix:
In order to use the linked radio stations straight out of Squeezebox
(m3u playlists), I instead changed my code from relative indexing (+1,
-1) to absolute indexing.


Code:
--------------------
    
  import lirc
  import time
  import telnetlib
  import RPi.GPIO as GPIO
  
  sockid = lirc.init("monitor", config_filename="~/App/SqueezeIRControl/monitor.lircrc", blocking=False)
  
  while True:
  try:
  telnetid = telnetlib.Telnet("localhost", 9090)
  	break
  except:
  	print "telnet connection error: try again ..."
  playpause = False
  
  relaypin = 5
  
  #GPIO.cleanup()
  GPIO.setmode(GPIO.BCM)
  GPIO.setup(relaypin, GPIO.OUT)
  GPIO.output(relaypin, GPIO.LOW)
  
  playidx = 0
  playcount = 0
  
  while True:
  codeIR = lirc.nextcode()
  if codeIR != []:
  if codeIR[0] == "KEY_DOWN":
  	print "mixer volume -5"
  		telnetid.write("mixer volume -5 \r")
  		tmp = telnetid.read_until("mixer volume -5")
  		print tmp
  elif codeIR[0] == "KEY_LEFT":
  	#print "playlist index -1"
  		#telnetid.write("playlist index -1 \r")
  		telnetid.write("playlist tracks ? \r")
  		telnetid.read_until("playlist tracks ")
  		playcount = int(telnetid.read_some())
  		playidx -= 1
  		if playidx<0:
  			playidx = playcount - 1
  		elif playidx>=playcount:
  			playidx = 0
  		telnetid.write("playlist index " + str(playidx) + " \r");
  		telnetid.read_until("playlist index");
  		playtmp = int (telnetid.read_some())
  		print "playlist index " + str(playtmp) + " (" + str(playtmp+1) + "/" + str(playcount) + ")"
  elif codeIR[0] == "KEY_RIGHT":
  	#print "playlist index +1"
  		#telnetid.write("playlist index %2B1 \r")
  telnetid.write("playlist tracks ? \r")
  telnetid.read_until("playlist tracks ")
  playcount = int(telnetid.read_some())
  playidx += 1
  if playidx>=playcount:
  playidx = 0
  telnetid.write("playlist index " + str(playidx) + " \r");
  telnetid.read_until("playlist index");
  playtmp = int (telnetid.read_some())
  print "playlist index " + str(playtmp) + " (" + str(playtmp+1) + "/" + str(playcount) + ")"                
  elif codeIR[0] == "KEY_UP":
  	print "mixer volume +5"
  telnetid.write("mixer volume +5 \r")
  		tmp = telnetid.read_until("mixer volume")
  		print tmp
  elif codeIR[0] == "KEY_MENU":
  		print "stop"
  		telnetid.write("stop\r")
  		tmp = telnetid.read_until("stop")
  		print tmp
  		GPIO.output(relaypin, GPIO.LOW)
  		playpause = False
  elif codeIR[0] == "KEY_PLAYPAUSE":
  		if playpause==True:
  			print "pause"
  			telnetid.write("pause\r")
  			tmp = telnetid.read_until("pause")
  			print tmp
  			playpause = False
  		else:
  			print "play"
  			GPIO.output(relaypin, GPIO.HIGH)
  			telnetid.write("play\r")
  tmp = telnetid.read_until("play")
  			print tmp
  			playpause = True
  	else:
  	    print codeIR
  #    else: # codeIR == []
  #    	print "nothing to do"
  
  time.sleep(0.05)
  
  GPIO.cleanup()
