Modern C : Converting Enums to Strings Without Fuss
In the realm of modern C , efficiently converting enums to strings becomes a breeze with the help of the Magic Enum header-only library.
Simplicity with Magic Enum
Magic Enum offers an elegant solution for converting enums to strings. With a simple include of the header, you can access the following functions:
auto color_name = magic_enum::enum_name(color); auto color = magic_enum::enum_cast<Color>(color_name);
These lines effortlessly extract the string name of an enum and convert a string back to the corresponding enum value.
Benefits of Magic Enum
Magic Enum not only provides simplicity, but also boasts many advantages:
Example Usage
Let's consider the following example:
enum Color { RED = 2, BLUE = 4, GREEN = 8 }; Color color = Color::RED; auto color_name = magic_enum::enum_name(color); // color_name = "RED" std::string color_name{ "GREEN" }; auto color = magic_enum::enum_cast<Color>(color_name); // color = Color::GREEN
Limitations
Magic Enum relies on a compiler-specific hack that currently supports Clang >= 5, MSVC >= 15.3, and GCC >= 9. Additionally, enum values must fall within a specific range by default or via customization.
Conclusion
Magic Enum empowers developers to effortlessly convert enums to strings in modern C applications, delivering both efficiency and elegance. Embrace its modern C features to streamline enum handling in your projects.
