Hello,
In my use of getopt.getopt, I would like to make a certain parameter
mandatory. I know how to specify such that a parameter must have a value if
it's specified, but I also want to make the parameter itself
mandatory(combined with a mandatory value, the result is that the user must
specify a value).
Here's code illustrating my point(see the TODO):
# Parse command line flags
# --------------------------------------------
configurationFile = ""
try:
opts, args = getopt.getopt( argv, "hVc:", ["help", "version",
"configuration-file="])
for opt,arg in opts:
if opt in ("-c", "--configuration-file"):
configurationFile = arg
if opt in ("-h", "--help"):
usage()
if opt in ("-V", "--version"):
print "Version:", common.version["Runner"]
sys.exit()
# TODO Can't getopt make an argument mandatory?
if configurationFile == "":
print "You must pass an URL/path to a configuration file, see
--help."
sys.exit(common.exitCodes["parameter"])
except getopt.GetoptError:
usage()
# --------------------------------------------
Is it possible?
Cheers,
Frans
