[New-bugs-announce] [issue46057] argparse: embedded groups may prevent options from being in help output

[László Attila Tóth]

New submission from László Attila Tóth <laszlo.attila.toth at gmail.com>:

I tried to use the following code where the --db-password is not shown in the --help output (Originally I wanted to use mutually exclusive groups but that feature also works strangely, so I changed them to regular groups).

def register_db_args(parser: argparse.ArgumentParser):
    grp = parser.add_argument_group('Database settings')
    grp.add_argument('--db-config', dest='db_config_file',
                     help='Config file containg all details including password')

    grp.add_argument('--db-host')
    grp.add_argument('--db-port')
    grp.add_argument('--db-user')

    xgrp = grp.add_argument_group()
    xgrp.add_argument('--db-password')
    xgrp.add_argument('--db-password-env')
    xgrp.add_argument('--db-password-file')
