Question 1

How do I iterate over all values in a C++ enum with Better Enums?

Accepted Answer

Use the _values() method provided by Better Enums, which returns an array of enum values that can be looped over at compile time in C++11 or at runtime in C++98, simplifying tasks like validation or UI generation.

Question 2

Better Enums vs magic_enum: which should I use?

Accepted Answer

Better Enums offers broader compiler support and C++98 compatibility, while magic_enum is a C++17 alternative with a cleaner syntax. Choose Better Enums for legacy projects or cross-compiler needs, and magic_enum for modern C++ with less macro usage.

Question 3

How can I convert an enum to a string in C++ using Better Enums?

Accepted Answer

Call the _to_string() method on any Better Enums instance, which provides compile-time string conversion for logging or serialization, and it works seamlessly with stream operators for output.

Question 4

Does Better Enums work with freestanding or embedded environments?

Accepted Answer

Yes, it doesn't use the heap and can be compiled without exceptions, making it suitable for minimal systems like embedded devices or kernels where resource constraints are tight.

Question 5

How to handle more than 64 constants in Better Enums?

Accepted Answer

You can extend the limit by modifying the library's macro definitions as per the documentation, but this requires manual tweaking and may break with updates, so it's best for advanced users.

Question 6

Can I use Better Enums inside a C++ class without issues?

Accepted Answer

No, directly inside a class is not supported; you must define the enum in a namespace and use a typedef or alias within the class, which adds an extra layer of indirection.
