Re: [Boost-users] [program_options] checking the presence of required arguments

Hi

My program has a bunch of required arguments. I grouped them into one options_description:

options_description required("Required options"); required.add_options() /* .... */ ;

// ...

options_description desc("Allowed options"); desc.add(required).add(other);

I'd like to check that all required arguments are in fact supplied without having to do

if(vm.count("arg1") == 0) { cerr << "usage error: arg1 is required\n"; return 1; }

for each of them. Any suggestions?

Nope. This is planned feature, not implemented at the moment. Sorry, Volodya
