Thanks so much. It is sufficient. using namespace boost::program_options;

Much of the style stuff is documented only if you wade through code. unreg will contain the unrecognized items.

Hello,

I would like to find a way to allow_unregistered program_options, as well as specify cls::unix_style ^ cls::allow_short, where cls is po::command_line_style.

The code I've got here doesn't seem to like unrecognized ones:

//vis_ are my visible options, vars_ is my variable map. po::store(parse_command_line(argc, argv, vis_, cls::unix_style ^ cls::allow_short), vars_); po::notify(vars_);

And then a slight variation with apparently a way to do this (untested), how to specify that cls?

// http://stackoverflow.com/questions/10178525/how-to-handle-unsolicited-parame... po::parsed_options parsed_ = po::command_line_parser(argc, argv) .options(vis_).allow_unregistered().run();

Possible? Thank ye...

Regards,

Michael Powell

Question about the options_description: how about parsing with multiple sections? For instance, I'd like to compose with a visible and hidden options strategy. po::options_description visible; //... po::options_description temp("Temp options); temp.add_options() ("myopt,m", "my option); visible.add(temp); Doesn't seem to parse. "myopt" falls through as unregistered. I can simply populate visible for now I think. But eventually would like to group the options according to various business needs. //-----------------------------------------------------------------------------
