Qt sucks at option parsing

Qt doesn't handle parsing program options (ie --foo=1) very well. But don't worry, boost program options can save the day! The problem is how to hook up boost::program_options to Qt's arguments after it has parsed Qt specific options.

#include <boost/program_options.hpp>
std::string qstr2str(const QString &qstr){
   return qstr.toStdString();
}

int main(int argc, char *argv[]){
QApplication application(argc, argv);
namespace po = boost::program_options;
po::options_description clspec("Options");
clspec.add_options()
("help", "see available options")
("arg1,a", po::value(&arg1)->default_value("banana"), "the arg1 option")
("arg2,b", po::value(&arg2)->default_value(false), "the arg2 option")
;

QStringList qargs = application.arguments();
std::vector args(qargs.size());
std::transform(qargs.begin(), qargs.end(), args.begin(), qstr2str);

po::variables_map vmap;
po::basic_command_line_parser parser(args);
parser.options(clspec).style(0).extra_parser(po::ext_parser());
po::store(parser.run(), vmap);
po::notify(vmap);
}

And with that you have parsed the options from Qt after it's had it's way with them
