Here's an example:
#include <boost/program_options.hpp>
#include <iostream>
#include <vector>
#include <string>
using namespace std;
namespace po = boost::program_options;
int main( int argc, char* argv[] )
{
vector< string > input_files;
string myoption;
po::options_description optdesc("Options");
optdesc.add_options()
("input-file,i", po::value< vector< string > >(&input_files),
"Input file name." )
("myoption", po::value< string >( &myoption ),
"My option explained.")
;
po::positional_options_description posopt;
posopt.add("input-file", 3);
po::variables_map varmap;
po::store(po::command_line_parser(argc,
argv).options(optdesc).positional(posopt).run(), varmap);
po::notify( varmap );
if( varmap.count("myoption") )
cout << "myoption = " << myoption << endl;
cout << "\nInput was:\n";
for( vector< string >::iterator si = input_files.begin(); si !=
input_files.end(); ++si )
cout << *si << "\n";
cout << endl;
return 0;
}
