[Python-Dev] getopt helper?

[Mark Hammond]

OK - general agreement.  Wheee :-)

How about this:

def getopt_or_die(opts,
                  long_opts=[],
                  usage=None,
                  prog_name=None,
                  args=None,
                  exit_code = 1):

if usage is None, we build a very simple usage string from
opts/long_opts.

If prog_name is None, we use os.path.basename(sys.argv[0]).  This is
printed just before the usage message.

If args is None, we use sys.argv[1:]

exit_code specifies the param to sys.exit() on invalid options.

I have based the ordering on my guess at the most likely to be used -
but maybe "prog_name" and "args" should be reversed?  This should
_not_ be all-singing, all-dancing, as it is simple to use the existing
getopt.getopt() directly for more esoteric requirements; the old 80-20
rule applies here :-)

If the general agreement continues, I will then knock together an
implementation.

Mark.
