class qubesadmin.tools.PropertyAction(option_strings, dest, metavar='NAME=VALUE', required=False, help='set property to a value')

Bases: argparse.Action

class qubesadmin.tools.QubesArgumentParser(vmname_nargs=None, **kwargs)

Bases: argparse.ArgumentParser

Parser preconfigured for use in most of the Qubes command-line tools.

Parameters:vmname_nargs (mixed) – The number of VMNAME arguments that should be consumed. Values include: * N (an integer) consumes N arguments (and produces a list) * ‘?’ consumes zero or one arguments * ‘*’ consumes zero or more arguments (and produces a list) * ‘+’ consumes one or more arguments (and produces a list)

kwargs are passed to argparser.ArgumentParser.

Currenty supported options:

--force-root (optional, ignored, help is suppressed) --offline-mode do not talk to hypervisor (help is suppressed) --verbose and --quiet

error_runtime(message, exit_code=1)

Runtime error, without showing usage.

Parameters:message (str) – message to show
