reflection_enum.cpp

Enumerate values and names with GMP reflection helpers. Demonstrates compile-time enumeration counting, name lookup, and retrieval of the full enumerator value list.

#include <gmp/gmp.hpp>
 
enum class Color {
    Red,
    Green,
    Blue,
};
 
int main() {
    constexpr auto values = gmp::enum_values<Color>();
 
    static_assert(gmp::enum_count<Color>() == 3);
    static_assert(gmp::enum_name<Color::Red>() == "Red");
    static_assert(values[0] == Color::Red);
    static_assert(values[1] == Color::Green);
    static_assert(values[2] == Color::Blue);
 
    return 0;
