Question

Does this library support reflecting Enum class member to string?

eesaber opened this issue a year ago · comments

For example, I have a enum class Foo

enum class Foo {
  kBar,
  kBaz,
};

And I want to convert to string

"kBar", "kBaz"

No, enum to string is not supported by RareCpp, at least in the short term I've decided I can't do this better than existing libraries (full-support for typical enum reflection activities is a very non-trivial problem) depending on your needs I recommend one of:

magic_enum - https://github.com/Neargye/magic_enum (no boilerplate required if your enums aren't using the same values in the same enum more than once, and the values are between -128 and 128 or are only bit-flag values)
wise_enum - https://github.com/quicknir/wise_enum (a macro-based approach to enum reflection with few restrictions)
a manual approach, e.g. https://godbolt.org/z/T7aT9eKMT

I am currently working on a side project in ORM (Object-Relational Mapping). One of my requirements is to be able to map database enum types to C++ enum types, and vice versa.

Thanks a lot for the suggestion of using the magic_enum library. I will take a look at it and see if it fits my needs.
