paul j3 added the comment: While
parser._negative_number_matcher is used during parser.parse_args() to check whether an argument string is a 'negative number' (and hence whether to classify it as A or O). parser._optionals._negative_number_matcher is used during parser.add_argument() to determine whether an option_string is a 'negative number', and hence whether to modify the _hasNegativeNumberOptionals flag. If this matcher is the general r'^-.+$', adding the default '-h' will set this flag. We don't want that. Using a different matcher for these two containers might work, but is awfully kludgy. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9334> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
