Is there a simple way to convert C++ enum to string?

Question

Suppose we have some named enums:

enum MyEnum {
      FOO,
      BAR = 0x50
};

What I googled for is a script (any language) that scans all

Answer 1

I have an incredibly simple to use macro that does this in a completely DRY fashion. It involves variadic macros and some simple parsing magic. Here goes:

#define AWESOME_MAKE_ENUM(name, ...) enum class name { __VA_ARGS__, __COUNT}; \
inline std::ostream& operator<<(std::ostream& os, name value) { \
std::string enumName = #name; \
std::string str = #__VA_ARGS__; \
int len = str.length(); \
std::vector strings; \
std::ostringstream temp; \
for(int i = 0; i < len; i ++) { \
if(isspace(str[i])) continue; \
        else if(str[i] == ',') { \
        strings.push_back(temp.str()); \
        temp.str(std::string());\
        } \
        else temp<< str[i]; \
} \
strings.push_back(temp.str()); \
os << enumName << "::" << strings[static_cast(value)]; \
return os;} 

To use this in your code, simply do:

AWESOME_MAKE_ENUM(Animal,
    DOG,
    CAT,
    HORSE
);
