Understanding `option long_options[]` when using `getopt_long` It looks to me like g++ should be making an implicit conversion from the unscoped enum to int* Even explicitly setting the type to int does not work: enum FROBNICATE : int { FROB_UNSET = -1, FROB_NO = 0, FROB_YES = 1 };
How to dynamically change base class of instances at runtime? This article has a snippet showing usage of __bases__ to dynamically change the inheritance hierarchy of some Python code, by adding a class to an existing classes collection of classes from which it
Is there a way to access slots in the superclass list in CLOS? This sends a message to the (sole) superclass of frob Perusing the CLOS documentation suggests that DEFCLASS merges all superclass information on class creation and thus this ability to communicate with the superclass is lost
Can you use nameof when hidden by in scope member? Well, doing a global find replace of nameof by NameOf might be the best solution if you can update all the code Then you remplace all NameOf that do not compile by nameof Obviously before doing that you have to push your old code to your version control system Assuming that your custom nameof never have any argument, it should works relatively well
Delphi: How to call a method when i click a control? 1 i have a method: procedure Frob(Sender: TObject); that i want to call when i click a menu item The method comes to me though an interface: animal: IAnimal; IAnimal = interface procedure Frob(Sender: TObject); end; The question revolves around what to assign to the OnClick event handler of a menu item (i e control): var animal: IAnimal
Why does Java enforce return type compatibility for overridden static . . . Obviously it's well known at runtime If I have a variable bar of type Bar, and I call s = bar frob (), the compiler would need to reverse engineer what type bar is to see if the return value is acceptable If determining the type at compile time is a super hard problem, this makes the compiler inefficient at best
Can anyone show me an example of MethodImplOptions. ForwardRef using System; using System Runtime CompilerServices; class Foo { Need to declare extern constructor because C# would inject one and break things [MethodImplAttribute(MethodImplOptions ForwardRef)] public extern Foo(); [MethodImplAttribute(MethodImplOptions ForwardRef)] static extern void Main(); static void Frob() { Console WriteLine("Hello!"); } } Now the magic sauce Open a Visual Studio
Why is specializing a monadic function with Identity less efficient . . . I'd expect this to be equally efficient as writing frob “by hand”, as Identity is a newtype that should be deleted at compile-time However, performance still suffers regardless, as is demonstrated by this criterion micro-benchmark:
