Features & Examples
- Basic
#include <magic_enum/magic_enum.hpp>
#include <iostream>
enum class Color { RED = -10, BLUE = 0, GREEN = 10 };
int main() {
Color c1 = Color::RED;
std::cout << magic_enum::enum_name(c1) << std::endl; // RED
return 0;
}
- Enum value to string
Color color = Color::RED;
auto color_name = magic_enum::enum_name(color);
// color_name -> "RED"
- String to enum value
std::string color_name{"GREEN"};
auto color = magic_enum::enum_cast<Color>(color_name);
if (color.has_value()) {
// color.value() -> Color::GREEN
}
// case insensitive enum_cast
auto color = magic_enum::enum_cast<Color>(value, magic_enum::case_insensitive);
// enum_cast with BinaryPredicate
auto color = magic_enum::enum_cast<Color>(value, [](char lhs, char rhs) { return std::tolower(lhs) == std::tolower(rhs); }
// enum_cast with default
auto color_or_default = magic_enum::enum_cast<Color>(value).value_or(Color::NONE);
- Integer to enum value
int color_integer = 2;
auto color = magic_enum::enum_cast<Color>(color_integer);
if (color.has_value()) {
// color.value() -> Color::BLUE
}
auto color_or_default = magic_enum::enum_cast<Color>(value).value_or(Color::NONE);
- Indexed access to enum value
std::size_t i = 0;
Color color = magic_enum::enum_value<Color>(i);
// color -> Color::RED
- Enum value sequence
constexpr auto colors = magic_enum::enum_values<Color>();
// colors -> {Color::RED, Color::BLUE, Color::GREEN}
// colors[0] -> Color::RED
- Number of enum elements
constexpr std::size_t color_count = magic_enum::enum_count<Color>();
// color_count -> 3
