C++ interlace marco or template

Question

Is there a marco or template can implement like

enum class Field {
    MY_MACRO_ADD(name,std::string)
    MY_MACRO_ADD(age,int)

will generate

enum class Field {
    name, age
};
std::string get_name();
int get_age();

Sure. I make a simple version.

Put these codes in a single file. That's how you want to expand your macros look like. (I have no idea if you're going to customize your class name, so I put it also in the macro)

// macro.h
enum class STRUCT_NAME
{
#undef ADD_PROPERTY
#define ADD_PROPERTY(type, name) name,
    STRUCT_BODY
};

#undef ADD_PROPERTY
#define ADD_PROPERTY(type, name) type get_##name();
STRUCT_BODY

Here is where you define your enum class.

// file where you define your enum
#define STRUCT_NAME Field
#define STRUCT_BODY \
    ADD_PROPERTY(string, name) \
    ADD_PROPERTY(int, age) \

Here is a demo. Hope my answer can help you.
