Currently, our codebase is using boost program_options as command-line parser in our testing framework. I want to implement a "consume-after-use" kind of rule in our command-line parsing.
What I mean by "consume-after-use" is, for example. After --option1 is used, I can then remove this --option1 in ARGC, ARGV. The main reason for this is I want to pass ARGC, and ARGV in another parser after I use the options I'm only concerned with.
Is this possible in boost program_option?
As you can read here the boost::program_options::variables_map inherites from std::map, so you can call std::map:erase on it:
namespace po = boost::program_options;
po::variables_map vm;
po::store(po::parse_command_line(ac, av, desc), vm);
po::notify(vm);
if (vm.count("option1")) {
// handle option1
...
// erase option1
vm.erase("option1");
if (vm.count("option1")) {
// never gonna happen
}
}
