- class novaclient.shell.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 usingargparse.SUPPRESS
), and provides a means to specify an alternate option to use using theuse
keyword argument toargparse.ArgumentParser.add_argument()
. The original action may be specified with thereal_action
keyword argument, which has the same interpretation as theaction
argument toargparse.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.- Parameters
option_strings – The recognized option strings.
dest – The attribute that will be set.
help – Help text. This will be updated to indicate the deprecation, and if
use
is provided, that text will be included as well.real_action – The actual action to invoke. This is interpreted the same way as the
action
parameter.use – Text explaining which option to use instead.
