Can you have subprocesss.Popen retain color in stdout/stderr?

I have the following code:

p = subprocess.Popen(cmd.split(' '), env=os.environ, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    while(True):
      log.info(p.stdout.readline())
      if(p.poll() is not None):
        break

Which works ok, except for the fact that it removes all color issued. Is there a way to retain this?

Add the following at the top of your Python script.

import os
os.environ['ANSIBLE_FORCE_COLOR'] = "TRUE"

Now if you run Ansible from Python by using subprocess.Popen, it will print the colors.

You do not specify whan cmd is, but some programs do not emit the escape sequences necessary for color output on a terminal when they determine that their standard output is not actually connected to a terminal.

Depending on the program you may or may not be able to override that.

With ansible, you can set the force_color configuration variable to 1 to force color output.
