Hi, I have created a git repository to receive the Boost.Tweener library. It is currently located at git://libclaw.git.sourceforge.net/gitroot/libclaw/boost-tweener (gitweb: http://libclaw.git.sourceforge.net/git/gitweb.cgi?p=libclaw/boost-tweener;a=...) I have started the templatization of the classes. Most easing functions are not template yet (only easing_none and easing_bounce are template) but will be in a few days. single_tweener has two template parameters, which are the type V of the tweened values and the scalar type S associated with V. All other classes do not need V and use only S. There are some points on which I would like to have a feedback: 1. single_tweener takes a reference to std::swap<V> (see line 90 of single_tweener.ipp): boost::bind( &std::swap<value_type>, boost::ref(val), _1 ); On the non-template version, value_type was double and this line caused a compilation error on Mac: error: no matching function for call to 'bind(<unresolved overloaded function type>, const boost::reference_wrapper<double>, boost::arg<1>&)'* The workaround was to use a custom non-template swap function. Do you have an idea on how to avoid the same issue in the new code? 2. The current directory structure looks like this: . ├── include │ └── boost │ └── tweener │ ├── detail │ │ └── impl │ │ └── easing │ └── easing └── test There is also a doc and examples folder but they are currently empty and thus not in the git repository. I'm not sure about the detail/impl/easing tree. Should I put the implementation of the easing functions in boost/tweener/easing/detail/impl instead? 3. Is there a prefered place to store the git repository? Regards, Julien Jorge
