An append action for argparse that overrides the default.

Project description

Provides oappend action for argparse that works almost like append, but skips the default list if the user gives any value for the option.

See issue 16399 for a discussion.

Example

You may import OverrideAppendAction and register it with a parser or use the provided parser:

from oappend import OverrideAppendArgumentParser

parser = OverrideAppendArgumentParser()
parser.add_argument('-n', action='oappend', type=int, default=[1, 2])
args = parser.parse_args(['-n3', '-n4'])  # Namespace(n=[3, 4])

With the standard append action the option would be set to [1, 2, 3, 4], combining your default with user choices.

Installation

pip3 install argparse-oappend
