This is offtopic, but I suggest looking into using optparse_ or
argparse_ instead of getopt. This would simplify your code to something
like::
parser = argparse.ArgumentParser(description='Preprocess a file.')
parser.add_argument('infile', default=sys.stdin,
type=argparse.FileType('r'))
parser.add_argument('-v', '--verbose', action='store_true')
parser.add_argument('-o', dest='outfile', default=sys.stdout,
type=argparse.FileType('w'))
parser.add_argument('-D', dest='defines', action='append')
args = parser.parse_args()
if args.verbose is not None:
log.setLevel(logging.DEBUG)
defines = {}
for define in args.define:
var, sep, val = define.partition('=')
defines[var] = val or None
try:
preprocess(args.infile, args.outfile, defines)
except PreprocessError, ex:
sys.stderr.write("preprocess: error: %s\n" % str(ex))
Additionally, if you include your help messages using the help= argument
to add_argument(), your usage message will be generated automatically.
