How to convert an enum to string in C++

  Full-blown preprocessor metaprogramming

There are also other approaches. Macro variants making use of `__VA_ARGS__` would be probably the best trade-off. If you want a slightly more ergonomic syntax, something like Metalang99 [1] will help (and the author even wrote a post about this exact subject [2]). Codegen is another option which may work better than other options depending on the situation and exact implementation strategy. And there is always the Reflection TS [3], which may or may not be incorporated to C++26...

Another project: thindx. Bindings for d3dcompiler + d3d9 + xinput have a lot of enums and flags:

• 50 results in 49 files for flags!: https://github.com/search?q=repo%3AMaulingMonkey%2Fthindx%20...

• 77 results in 69 files for enumish!: https://github.com/search?q=repo%3AMaulingMonkey%2Fthindx+en...

• I still do things by hand somtimes, for reasons that elude my recollection: https://github.com/MaulingMonkey/thindx/blob/127d75f9de91f73...

And these are baby numbers compared to an actual professional gamedev codebase. Attention to detail makes me fairly comfortable with this much hand-generated nonsense in my one man show, but bugs still crop up... and there are people I would dread handing maintainence of such a project over to that I've worked with in a professional capacity, who simply do not care to exercise the same level of care as I do when editing such stuff.

• Better Enums

  5 1,597 3.7 C++

  C++ compile-time enum to string, iteration, in a single header file

I really like better_enums instead of magic_enums. There’s no limit on enum size with it: http://aantron.github.io/better-enums/

It was heavily used at a former employer of mine, so definitely a solid production-ready solution.
