Question. How to use switches together with environment variables? #497

Closed ilejn closed 2 months ago

ilejn commented 2 months ago

Hello, I have simple command line flags, that perfectly work with action="store_true". I would like to have it controlled via environment as well, but it does not work well.

Ideally I want to specify myscript --debug or DEBUG=true myscript and it works indeed, unless I try DEBUG=false myscript. The latest one is converted to True as well.

The question is what is the best way to achieve the goal.

Switching to type=bool works, but not convenient as for commandline. Attempt to have two parameters with same dest is not successful (obviously).

My bad, the attempt to have two parameters with same dest IS successful. I have

parser.add_argument(
    "--silent",
    action="store_true",
    dest="silent_flag",
    default=False,
    help="no log"
)
parser.add_argument(
    "--silentflag",
    "--silent-flag",
    dest="silent_flag",
    type=bool,
    default=False,
    help="no log"
)
