from optparse import OptionParser, Option
class MyOption (Option):
ACTIONS = Option.ACTIONS + ("extend",)
STORE_ACTIONS = Option.STORE_ACTIONS + ("extend",)
TYPED_ACTIONS = Option.TYPED_ACTIONS + ("extend",)
ALWAYS_TYPED_ACTIONS = Option.ALWAYS_TYPED_ACTIONS + ("extend",)
def take_action(self, action, dest, opt, value, values, parser):
if action == "extend":
lvalue = value.split(",")
values.ensure_value(dest, []).extend(lvalue)
else:
Option.take_action(
self, action, dest, opt, value, values, parser)
parser = OptionParser(option_class=MyOption)
parser.add_option("-i", "--input", action="extend")
options, args = parser.parse_args()
print options
If you had problems understanding the documentation perhaps you can suggest
an improvement.
