Command line parameter problem

We are trying to develop a (Tag) plugin to switch camera's from the command line. We thought we had it working since it works when we open a c4d file in the GUI and it switches to the right camera, but when we render on the render farm (command line / nogui) it doesn't work. It gives us:

File "'CommandLine.pyp'", line 31, in Execute
AttributeError: 'module' object has no attribute 'argv'

In the log

This is the code:

import c4d
import os
import sys
import getopt

print 'Number of arguments:', len(sys.argv), 'arguments.'
          print 'Argument List:', str(sys.argv)
              opts, args = getopt.getopt(sys.argv,"c:s:",["camera=","setting="])
          except getopt.GetoptError as err:
              print "Error: Unknown command line options!"
              print "We only support -c|--camera= -s|--setting="
              return False
          camera = ''
          setting = ''
          for opt, arg in opts:
              if opt in ("-c", "--camera") :
                  camera = arg
                  print "camera = ", camera
              elif opt in ("-s", "--setting") :
                  setting = arg
                  print "setting = ", setting
          commandRead = 1
          adraw = doc.GetActiveBaseDraw()
          roots = doc.GetObjects()
          cameraFound = 0
          for obj in roots:
              if obj.GetName() == camera:
                  cameraFound = 1
          if cameraFound == 1:
              camname = adraw.GetSceneCamera(doc).GetName()
              print "Camera :", camname, "selected"
              print "Camera not Found!"

Is getopt not availble during load? Of are we missing something here? I hope someone can help. We need this for a customer job.

To get the Cinema 4D command line arguments implement PluginMessage() and filter the C4DPL_COMMANDLINEARGS message. In this message sys.argv holds the command line arguments.
You can then store them using a global variable to be used afterwards in your Tag's Execute().

See Command Line Arguments in the Python documentation for a code snippet and more information.

Thank you very much :) I'm going to try that.
