DeprecatedAction
(option_strings, dest, help=None, real_action=None, use=None, **kwargs)¶Bases: argparse.Action
An argparse action for deprecated options.
This class is an argparse.Action
subclass that allows command
line options to be explicitly deprecated. It modifies the help
text for the option to indicate that it’s deprecated (unless help
has been suppressed using argparse.SUPPRESS
), and provides a
means to specify an alternate option to use using the use
keyword argument to argparse.ArgumentParser.add_argument()
.
The original action may be specified with the real_action
keyword argument, which has the same interpretation as the
action
argument to argparse.ArgumentParser.add_argument()
,
with the addition of the special “nothing” action which completely
ignores the option (other than emitting the deprecation warning).
Note that the deprecation warning is only emitted once per
specific option string.
Note: If the real_action
keyword argument specifies an unknown
action, no warning will be emitted unless the action is used, due
to limitations with the method used to resolve the action names.
Initialize a DeprecatedAction
instance.
