Visual C++ equivalent of __FILE__ , __LINE__ and __PRETTY_FUNCTION__

Question

GCC compiler gives me the following macros:

• __FILE__ so that I can print out the file name + directory.
• __LINE__ so that I c

Answer 1

Using c++14 with constexpr you can use this: WHERE macro.

Based on usage of:

• __PRETTY_FUNCTION__
• __LINE__

#include "string/ConstexprString.hpp"

#define S1(x) #x
#define S2(x) S1(x)

// WHERE - const char* const should be used as temporary value
#define WHERE (string::make(__PRETTY_FUNCTION__) + ":" + string::make(S2(__LINE__))).get()

// It is safe to store e.g. `constexpr auto where = WHERE_STR;`
#define WHERE_STR (string::make(__PRETTY_FUNCTION__) + ":" + string::make(S2(__LINE__)))

Example usage:

    // Called: void (anonymous namespace)::exampleUseCaseWhere(int):18
    std::cout << "Called: " << WHERE << std::endl;
