It's a pity that the argument parsing modules in the standard library
are so verbose that everybody is reinventing the same thing :-( It
looks like you have reinvented plac: http://pypi.python.org/pypi/plac
After looking into it, Plac's default help display isn't very helpful;
you need to massage your application a fair amount before generating
nice, complete-looking argument lists and such. For example:
def main(verbose: ('prints more info', 'flag', 'v'), dsn: 'connection
string'):
@annotate(dsn="connection string", verbose="prints more info")
def main(dsn, verbose=False):
The latter is marrow.script, and even without the annotation a more
complete help text is generated. The -v and flag nature are assumed
from the first unique character and default value. (Flags, when
present on the command line, invert the default value.) Py3k
annotations haven't been implemented yet, though.
Also included is an easy way to simulte command-line execution (i.e. by
reading arguments passed by hand and by returning the exit code, vs.
reading sys.argv and calling sys.exit()) for unit testing purposes.
Plac appears (from the documentation) to be written on top of argparse.
