[Boost-users] Re: boost::program options question. Implicit() doesn't seem to work

Alexis H. Rivera-Rios wrote:

According to the documentation the line: desc.add_options() ("debug", po::valuestd::string()->implicit(), "enable debugging" );

enables me to do something like this: myexec --debug

However, if I do that I get an assertion error. The code requires a string so this will work: myexec --debug whatever

What am I doing wrong? Is it me or is it the library?

I think it's the library. But in any case, I plan to remove the 'implicit' flag in 1.33. Why do you want it? What about: desc.add_options() ("debug", bool_option(), "enable debugging") ? - Volodya
