Hi,
Is it possible to generate a description in the following format using program_options?
[...] I was in the process of writing a message asking for something similar, when I saw this ;) I was only thinking about the location of the default value though, instead of -t [ --min-trunc ] arg (=1.77635683940025e-15) Minimum desired truncation error per site of the effective basis I am putting the default as part of the description text: -t [ --min-trunc ] arg Minimum desired truncation error per site of the effective basis [default 1.77635683940025e-15] but a way to achieve this automatically would be great. Also, an overload of options_description_easy_init::operator() that takes a std::string as the last parameter would be really useful, save having to use .c_str() ugliness. By the way, there was never any response to the query at http://thread.gmane.org/gmane.comp.lib.boost.user/21083/focus=21084 concerning multiple boolean switches. If no one else does first sometime I'll get around to trying the solution I suggested in the root mail (a new class derived from value_semantic) - but I'm not even sure if that is the correct way to achieve it.
