c++ - Taking the address of a literal, not a `constexpr` -

-
strictly according rules of c++14, @ least ones given cppreference.com , isn't line (1) constant expression? constexpr const int* addr(const int& ir) { return &ir; } constexpr const int* tp = addr(5); // (1) it's true not address constant expression , because &ir isn't address of static object ( &ir address of temporary in context, cannot known in compilation-time). but core constant expression because doesn't violate of back-listed rules of core constant expression , has no back-listed rules getting address of object. no, addr(5) not constant expression, , therefore posted code ill-formed. yes, correct addr(5) core constant expression. i can see why might think cppreference page alone core constant expressions, integral constant expressions, converted constant expressions, literal constant expressions, reference constant expressions, , address constant expressions types of constant expression. true definition given in c++14 [...

Auto git fetch when the Android studio (IntelliJ) is idle -

-
i use git fetch have latest information server. git fetch won't change code base , not take time , network traffic. when go toilet or else auto git fetch . there way this? enabling automatic fetch in intellij asked before. see issue idea-24057 , idea-100846 check out gittoolbox : has auto fetch functionality. feature not seem available in native intellij alone (ie: need find third-party plugin) it indeed nice if work because configuration options in file | settings | version control | background ignored git , doesn't seem indicated in ui or help. also, people coming atlassian sourcetree expect happen automatically. messes merging remote branches because remote branches not date automatically (something sourcetree users used to). hampers (full) adoption of idea.
