C++ Enum Class

Features

• C++17
• Header-only
• Dependency-free
• Enum to string
• String to enum
• Retrieve sequence of Enum values or names

Examples

ENUM_CLASS(Animal, int,
    CAT = -5, DOG, HORSE = 7);

• Enum value to string

  Access enum class metadata using enum_class namespace functions:

  auto animal_str = enum_class::Name(Animal::DOG);		// no need to specify <Animal>
  // animal_str == "DOG"

  Alternative method using automatically generated meta class:

  auto animal_str = AnimalMeta::Name(Animal::DOG);
  // animal_str == "DOG"

• String to enum value

  Access enum class metadata using enum_class namespace functions:

  auto animal = enum_class::Value<Animal>("HORSE");		// need to specify <Animal>
  if (animal) {
    // *animal == Animal::HORSE
  }

  Alternative method using automatically generated meta class:

  auto animal = AnimalMeta::Value("HORSE");			// no need to specify <Animal>
  if (animal) {
    // *animal == Animal::HORSE
  }

• Enum values sequence

  auto animals = enum_class::Values<Animal>();
  // animals == { Animal::CAT, Animal::DOG, Animal::HORSE }
  // animals[0] == Animal::CAT

• Enum names sequence

  auto animal_names = enum_class::Names<Animal>();
  // animal_names == { "CAT", "DOG", "HORSE" }
  // animal_names[0] == "CAT"

Remarks

Integration
