I have an application, which spawns off other applications.  As input, it takes in environment variables and arguments to pass to the resultant application.  For instance:

mutate -E “env_var1=val” -a “.” ls

This will run:

ls .

and the environment will only have “env_var1” equal to “val”

So.  Something funny comes along when I try to pass “-e” as an argument.

So, in the above would be:

mutate -a “-e” –a “foo” xterm

The program options parser attempts to parse the “-e”, and says “I don’t know what it is”.

Any thoughts on having it skip that option?

Code Snippits:

    po::options_description visible("Program options. Usage %1%");

    visible.add_options()

        ("env,E", po::value<string_vector_t>(), "Specify an environment variable to run the executable with. In the form of foo=bar")

        ("arg,a", po::value<string_vector_t>(), "Specify a command line argument to pass to the executable")

    ;

// Set up some hidden options

    po::options_description hidden("Hidden options");

    hidden.add_options()

        ("executable", po::value < std::string>(), "the executable to run")

    ;

// Set up positional arguments.  They are going to be execute

    po::positional_options_description pos;

    pos.add("executable", 1);      // There can only be 1 item executed

// Consolidate all the options into a single one

    po::options_description all_options("All Options");

    all_options.add(visible);

    all_options.add(hidden);

// Parse the command line options

    po::store(po::command_line_parser(argc, argv).options(all_options).positional(pos).run(), vm);

    po::notify(vm);
