Announcing argparse 0.6 ----------------------- argparse home: http://argparse.python-hosting.com/
argparse single module download: http://argparse.python-hosting.com/file/trunk/argparse.py?format=raw argparse bundled downloads at PyPI: http://www.python.org/pypi/argparse/ About this release ================== This release adds support for argument groups, and fixes a bug in the display of required options. Also, the source distribution of this release should now include the tests. Note that the 'outfile' type is still deprecated and will likely be removed in the next release. Please update your code to use the new FileType factory. New in this release =================== * Required options are no longer displayed with brackets (so that they no longer look optional). * The source distribution includes ``test_argparse.py``, argparse's test suite. * Arguments can now be grouped into user-defined sections instead of the default "positional arguments" and "optional arguments" sections:: >>> parser = argparse.ArgumentParser(prog='PROG', add_help=False) >>> xgroup = parser.add_argument_group('xxxx') >>> xgroup.add_argument('-x', help='x help') >>> ygroup = parser.add_argument_group('yyyy') >>> ygroup.add_argument('y', help='y help') >>> parser.print_help() usage: PROG [-x X] y xxxx: -x X x help yyyy: y y help About argparse ============== The argparse module is an optparse-inspired command line parser that improves on optparse by: * handling both optional and positional arguments * supporting parsers that dispatch to sub-parsers * producing more informative usage messages * supporting actions that consume any number of command-line args * allowing types and actions to be specified with simple callables instead of hacking class attributes like STORE_ACTIONS or CHECK_METHODS as well as including a number of other more minor improvements on the optparse API. To whet your appetite, here's a simple program that sums its command-line arguments and writes them to a file:: parser = argparse.ArgumentParser() parser.add_argument('integers', nargs='+', type=int) parser.add_argument('--log', default=sys.stdout, type=argparse.FileType('w')) args = parser.parse_args() args.log.write('%s\n' % sum(args.integers)) args.log.close() -- http://mail.python.org/mailman/listinfo/python-list
