Title: Call a Python script from VoxCommando
Post by: SaScot007 on March 16, 2012, 04:23:50 PM

Hi, I am trying to run a Python script from voxcommando

This is the command that I am trying to run:

c:\python32\python.exe s:\prog\VC_RunPython.py alpha red

This command works OK from the DOS prompt, but when I set it up from VC I dont think it passes the parameters correctly to Python
  - or I don't understand how to do it !!

These are the parts of the command line:
c:\python32\python.exe          << this is the python executable
s:\prog\VC_RunPython.py        << this is the name of the python script
alpha                                     << this is runtime parameter 1 (using payload list 1)
red                                       << this is runtime parameter 2 (using payload list 2)


This is the Python script:  all it does is write out to a file the values of the parameters it received
----------------------------------------------------------------------------------
#s:\prog\VC_RunPython.py
import sys
import datetime
 
now = str(datetime.datetime.now())

myfile = open(r's:\prog\test.txt','a')
myfile.write('\nStarting ... '+now+'\n')

print ('ProgramName is: ' + sys.argv[0])
for i in range(len(sys.argv)):
    writeString = 'Parameter ['+str(i)+']:  ' +sys.argv +'\n'
    print(writeString)
    myfile.write(writeString)
myfile.close()
------------------------------------------------------------------------------------------------

When I test in VC it does the OSD fine, but it just flashes a black DOS box for the python call

I have attached the screenshots -

Any help would be much appreciated! I think the ability to call Python would be a great facility for VC as I an using Python for Home Automation.

Thanks!!  SaScot007

Hi SaScot007,

Welcome to VoxCommando.  I think you should try putting all your parameters together in a single string as the 2nd parameter for the launch.rawpam action.  (first param is the executable path as you have done).

Currently you are passing {2} and {3} as the 3rd and 4th parameters but the launch command is only expecting a single parameter for the executable and a single string for all of the "command line params".

try this:
c:\python32\python.exe                s:\prog\VC_RunPython.py {1} {2}

btw a great way to call python scripts and to combine with other home automation stuff, is to use eventGhost.

If it works correctly it will still just flash a black box, unless your python script is asking for user input or something similar.

Hi - thanks that works fine!

Is there any way to not have the black DOS box pop up?

Thanks again ...
