What is Magic Enum?

Header-only C++17 library provides Enum-to-String and String-to-Enum functions.

• magic_enum::enum_to_string used to obtain string enum name from enum variable.
• magic_enum::enum_from_string used to obtain enum variable from enum string name.

Features

• C++17
• Header-only
• Dependency-free
• Compile-time
• Enum to string
• String to enum

Examples

• Enum to string

auto color = Color::RED;
// Enum variable to string enum name
auto color_name = magic_enum::enum_to_string(c);
if (color_name.has_value()) {
  // color_name.value() -> "RED"
}

constexpr auto cx_color = Color::BLUE;
// Static storage enum variable to string enum name
auto cx_color_name = magic_enum::enum_to_string<cx_color>();
if (color_name.has_value()) {
  // cx_color_name.value() -> "BLUE"
}

• String to enum

// String enum name to enum variable
auto color = magic_enum::enum_from_string<Color>("GREEN");
if (color.has_value()) {
  // color.value() -> Color::GREEN
}

Integration

You have to add required file magic_enum.hpp.
