OK, first off there's an email invitaion to the Sandbox on it's way, once you're signed up then checkout using: svn co https://svn.boost.org/svn/boost/sandbox [local-path] and you'll find a copy of the type_traits lib under /type_traits/.
I have done this. I have added (yet only local) my file and a test file. How can I run the tests automatically?
Procedure wise, if you can follow the existing structure that would be great: use one header per trait and one one .cpp file for each trait test etc.
Are you sure one header for all comparison operators would not be better than one for each?
With regard to macro usage, the easiest way is to define say for example boost::detail::is_equality_comparible_imp with a member "value" that is either true or false, and then add:
BOOST_TT_AUX_BOOL_TRAIT_DEF1(is_equality_comparible,T,::boost:: detail::is_equality_comparible<T>::value)
This works fine, thanks. F. Bron Avis : Ce message et toute pièce jointe sont la propriété d'Alcan et sont destinés seulement aux personnes ou à l'entité à qui le message est adressé.
