Надоело изобретать велосипед, решил начать использовать готовые библиотеки.
Boost установил скомпилированный, из реп.
Открываю примеры, например, boost/libs/program_options/example/first.cpp
#include <boost/program_options.hpp>
namespace po = boost::program_options;
#include <iostream>
#include <iterator>
using namespace std;
int main(int ac, char* av[])
{
try {
po::options_description desc("Allowed options");
desc.add_options()
("help", "produce help message")
("compression", po::value<double>(), "set compression level")
;
po::variables_map vm;
po::store(po::parse_command_line(ac, av, desc), vm);
po::notify(vm);
if (vm.count("help")) {
cout << desc << "\n";
return 0;
}
if (vm.count("compression")) {
cout << "Compression level was set to "
<< vm["compression"].as<double>() << ".\n";
} else {
cout << "Compression level was not set.\n";
}
}
catch(exception& e) {
cerr << "error: " << e.what() << "\n";
return 1;
}
catch(...) {
cerr << "Exception of unknown type!\n";
}
return 0;
}
