How to create to string macro for ENUM?
I created a simple enum macro that creates a to_string method for the enum. This has been done before, but my version is designed to compile quickly. From what I can tell, existing libraries use deep preprocessor macros and lots of template instantiations which is taxing for large enums.
Which is an example of an enum in VBA?
It is a type that contains an enumeration of constants. A good example of an enumeration is a list of types of cars e.g. Sedan, Hatchback, SUV, Truck etc. Enumerations make it easy to group these values. Enums can be used as variable, however, an Enum is in fact a numeric variable…
How are enumerations used in the VBA language?
Enumerations are often used in various languages to list certain variable variations within a single object to make them easy to find or list. The VBA Enum is a equally valuable construct – allowing you to clean up your mess by grouping a collection of constants into a single object you can easily explore.
How to create a string array in C + +?
Simple solution is to have a separate macro for each different count. Using 2-level “stringify” macro pattern (read more about it here) you can do something like this: If you want just one macro which takes variable number of arguments, it gets a bit messy, as shown in the other answers.
How to ENUM a string in C + + 17?
One possible idea could be using the C++ compiler capabilities to generate C++ code at compilation-time using meta-programming tricks based on variadic template class and constexpr functions… Magic Enum header-only library provides static reflection for enums (to string, from string, iteration) for C++17.
Is there a way to map enum to strings automatically?
I have long been looking for an elegant, one-line solution to map enum to strings automatically, for use with the << and >> stream operators. I know that a lot of macros have been proposed to achieve that, but I never found a really simple scheme, with only one macro call.
Is there a C + + 17 enum reflection macro?
So, at least for enums declared through this macro, you can have the proposed C++17 enum reflection now, in C++11/C++14. It is straightforward to extend this answer to the features of the library – nothing “important” is left out here. It is, however, quite tedious, and there are compiler portability concerns.
