Re: [Boost-users] commandline options

6 Nov 2007


      Here's an example:

#include 
#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;
}

Have you seen the Boost.ProgramOptions library here:
