I have some command line arguments categorized in groups as follows:
cmdParser = argparse.ArgumentParser()
cmdParser.add_argument(\'mainArg\')
groupOne = cm
I was looking for a solution for this for a very long time,
And I think I finally got it.
So I will just put it here...
from argparse import ArgumentParser
def _parse_args():
parser = ArgumentParser()
parser.add_argument('-1', '--flag-1', action='store_true', default=False)
parser.add_argument('-2', '--flag-2', action='store_true', default=False)
parser.add_argument('-3', '--flag-3', action='store_true', default=False)
args, unknown = parser.parse_known_args()
print(f"args : {args}")
print(f"unknown : {unknown}")
hidden = ArgumentParser(add_help=False)
hidden.add_argument('-d', '--debug', action='store_true', default=False)
hidden_args = hidden.parse_args(unknown)
print(f"hidden_args : {hidden_args}")
if __name__ == "__main__":
_parse_args()
as a result:
show help:
ubuntu → playAround $ ./test.py -h
usage: test.py [-h] [-1] [-2] [-3]
optional arguments:
-h, --help show this help message and exit
-1, --flag-1
-2, --flag-2
-3, --flag-3
With debug flag:
ubuntu → playAround $ ./test.py -d
args : Namespace(flag_1=False, flag_2=False, flag_3=False)
unknown : ['-d']
hidden_args : Namespace(debug=True)
with flags 1 and 2:
ubuntu → playAround $ ./test.py -12
args : Namespace(flag_1=True, flag_2=True, flag_3=False)
unknown : []
hidden_args : Namespace(debug=False)
with flags 1 and 2 and debug:
ubuntu → playAround $ ./test.py -12 -d
args : Namespace(flag_1=True, flag_2=True, flag_3=False)
unknown : ['-d']
hidden_args : Namespace(debug=True)
The only thing you can't do with this approch is to pass the debug short flag along side to the other short flags:
ubuntu → playAround $ ./test.py -12d
usage: test.py [-h] [-1] [-2] [-3]
test.py: error: argument -2/--flag-2: ignored explicit argument 'd'
