Hello all. I am using the boost::program_options library for configuration files with great success. I'm wondering if it's possible to use the library using a string as a source, instead of a config file. I read the configuration file with code like this: if (vm.count("config")) { string f = vm["config"].as<string>() ; ifstream ifs(f.c_str()); store(parse_config_file(ifs, config_file_options), vm); po::notify(vm); } but what I'd also like to do is something along these lines, with a string as the original source instead of a file specified with my 'config' command line option: string str = "port = 3000 \n tmpdir = /tmp \n"; // something like this. this is what's in the config file. istringstream iss(str, istringstream::in); store(parse_config_file(iss, config_file_options), vm); po::notify(vm); These lines compile and execute without error but don't actually appear to update the 'vm'. Am I doing something wrong or is this not possible with the current incarnation of program_options?
