Hi,

I have a question regarding the validators namespace of program_options documentation.

That namespace is referenced in the tutorial in http://www.boost.org/doc/libs/1_55_0/doc/html/program_options/howto.html and some of its functions are used but there is no documentation related with that namespace. Actually, it does not even appears in the reference manual of the lib.

Is that intended ?

Alain, nope, it's not intended. The problem it seems that documentation build only picks stuff in include/boost/program_options/, but not 'detail' subdirectory, and that namespace, as well as the 'validate' function, are defined in there. It's sounds like historical accident, as 'validate' is a function that is meant to be overridden, so at least some definition must be in non-detail headers. - Volodya
