New submission from Rémi Rampin: This works correctly on Python 3.4.
On Python 2.7, argparse seems to completely and silently ignore arguments in some conditions, for instance this setup will cause --verbose to be ignored on the main parser: options = argparse.ArgumentParser(add_help=False) options.add_argument('-v', '--verbose', action='store_true') parser = argparse.ArgumentParser(parents=[options]) subparsers = parser.add_subparsers() parser_cmd = subparsers.add_parser('cmd', parents=[options]) Full runnable example here: http://paste.pound-python.org/show/XfVVhdJHSPISXLP1lASd/ Might or might not be related to #9351, workarounds welcome. ---------- components: Library (Lib) messages: 232679 nosy: remram priority: normal severity: normal status: open title: argparse silently ignores arguments type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23058> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
