Hi there,
I'm new in dlang I specially like betterC. I was hoping that d fibers would be implemented in without using classes, but there are not. Is there another way how to use async/await in dlang better c?

Thank you for your help

There are no async/await keywords in D yet. Have you tried searching for compatible packages in dub?

I'm not aware of any -betterC package specifically for coroutines.

I have some work done in this regard, but sadly the library itself isn't really usable at all so if you want to put in the effort you'd have to probably extract the code out, but that's quite a bit of effort: https://github.com/BradleyChatha/bcstd/tree/master/source/libd/async

To make it even more annoying there's also an ASM file you'd have to deal with: https://github.com/BradleyChatha/bcstd/blob/master/source/asm/coroutine.nasm

Alternatively you could go for a C coroutine library, which should function ok-ish, but not perfect, but would likely be much easier than the above suggestion.

Or write your own, as is a common suggestion around here :3

Libaco provides the general gist of how it works: https://github.com/hnes/libaco#proof-of-correctness

I feel I didn't make it clear enough that extracting the code would be way too much effort than its worth, especially since I'm not even sure it runs on Linux. So I really wouldn't suggest going down that route.

A C or C++ concurrency library should work.

Another option, if you just want fibers but not true concurrency, would be to do some assembly trickery. Probably not too hard if you know assembly, but not very portable.

If the reason you're using -betterC is targeting asm.js or WebAssembly, you will need to use the JavaScript APIs of your environment for concurrency.

On windows you can use the fiber api https://docs.microsoft.com/en-us/windows/win32/procthread/fibers just as you would do in C.
