Hi,
boost-1.32.0-6
I've tried to find in the program_options docs how to specify a regular boolean switch. If I use <bool>, it still demand putting something
That's what I would like to have ./prog -t
and not ./prog -t1
Right now, when using <bool> it will throw an exception if I'm not using the -t1 notation.
Am I missing here something?
Use zero_tokens(), e.g.: namespace po = ::boost::program_options ; bool the_flag ; po::options_description opts( "Options" ) ; opts.add_options()( "the-flag,t" , po::value( &the_flag )->zero_tokens() ) //... ; -- François Duranleau LIGUM, Université de Montréal "There are as many truths as there are people." - from _Neon Genesis Evangelion_ _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
