Handling arguments after --

[GoogleCodeExporter]

optparse stopped parsing arguments after --, how can the same be achieved with 
argparse?

For example:

commmand -v -- --option

I want argparse handle arguments only until --. The rest should be left 
unparsed, ready to pass in subprocess

Seems like you've uncovered a bug. It does handle "--" correctly, unless you 
don't have any positional arguments. Can you please file this bug on the Python 
tracker (bugs.python.org)? All future work on argparse will occur in the Python 
trunk, not here.

Sample code:

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
>>> parser.add_argument('foo')
>>> parser.parse_args(['-v', '--', '--foo'])
Namespace(foo='--foo', v=True)

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', action='store_true')
>>> parser.parse_args(['--', '-f'])
usage: [-h] [-v]
: error: unrecognized arguments: -- -f
