Detailed Description

Easy processing of argc and argv.

Example:

int main(int argc, char** argv)
{
    CommandLineParser cmd;
    CommandLineParser::PositionalArg<std::string> inFileName(cmd, "input file", "Input mesh to compile");
    CommandLineParser::PositionalArg<std::string> outFileName(cmd, "output file", "Output compiled mesh file");
    CommandLineParser::Flag prt(cmd, "prt", "Enable radiance transfer precomputation");
    CommandLineParser::Option<float> scale(cmd, "scale", "Mesh scale factor", 1.0);
    CommandLineParser::HelpFlag help(cmd);

    try
    {
        cmd.Parse(argc, argv);
    }
    catch(std::exception& e)
    {
        std::cerr << e.what() << std::endl;
        cmd.PrintHelp();
        return EXIT_FAILURE;
    }

    // Get value by dereferencing:
    std::cerr << "Input file: " << *inFileName;
}
