Stefan,

it depends on how far you are ready to go ;) What you request is possible, but that will not work (AFAIK) from the scratch.

What you need is custom handling of the options parsed.

namespace po = boost::program_options;

template<class CharT>
void handle_parsed_option(po::basic_option<CharT> const& parsed_option)
{
//parse it
}

//program options are used to properly parse values
// so all options parsed are valid
po::options_description options("Option Parser");
options.add_options()
("*", po::value<int>(), "dummy placeholder")
;

po::parsed_options const& opts = po::parse_config_file(input, options);

::std::for_each(opts.options.begin(), opts.options.end(), &handle_parsed_option<char>);

Hope that helps.

Best Regards,
Ovanes

Hi,

is there a general description of the config file syntax that
program_options uses available? Like if it's case-sensitive, if you can
quote arguments, etc ... currently i'm wondering if I can fill a vector
from one line, like
val = foo bar baz
with foo, bar, and baz as the values ... is this possible with some
separator?

Regards,
Stefan
