No auto is awesome. I've started a new simulation Montecarlo simulation program for my PhD and use exclusively auto to declare my variables. So far I was never surprised by type and I get the benefit that I force the compiler to check that each of my variables is initialized, incredibly useful! At first it seems a bit odd but once you are used to only using auto it gets convenient with no noticeable downside. A good post on that topic is. http://herbsutter.com/2013/08/12/gotw-94-solution-aaa-style-almost-always-auto/ I can also recommend the chapter about 'auto' in Effective Modern C++ > 2015-06-05 6:43 GMT+02:00 RJ Ryan <rr...@mixxx.org>: > >> Mixxx is switching to C++11!

This can be done rather easily because it is just a minor addition to C++11. A obvious one is the make_unique and make_shared template. namespace std { // we use C++11 as a minimum requirment. make_unique was added in C++14 to the // standard. So always use this. template <typename T, typename... Ts> std::unique_ptr<T> make_unique(Ts&&... params) { return std::unique_ptr<T>(new T(std::forward<Ts>(params)...)); } template <typename T, typename... Ts> std::shared_ptr<T> make_shared(Ts&&... params) { return std::shared_ptr<T>(new T(std::forward<Ts>(params)...)); } } // namespace std This sure that we allocate the smartpointer and real pointer adjacent to each other in ram, It can be later used like auto tmp = make_unique<QWidget>(var1, var2, var3); ------------------------------------------------------------------------------ _______________________________________________ Get Mixxx, the #1 Free MP3 DJ Mixing software Today http://mixxx.org Mixxx-devel mailing list Mixxx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mixxx-devel
