Re: [Boost-users] Program options negative arguments

If I setup a multitoken option like this:

desc.add_options() ("NumberList", po::value<vector<int> >()->multitoken(), "List of numbers.")

and then call the program with: ./Program --NumberList 1 2 -3 4

it treats the number "-3" as a new flag so it produces an "unknown option" error. Is there a way to handle this negative argument?

Use a command line style that does not think '-3' is an option. Multitoken options are BAD, exactly because of these ambiguities. - Volodya
