zigstr VS dstep

For Unicode text processing you can take a look at Ziglyph https://github.com/jecolon/ziglyph and for a sample UTF-8 string structure, Zigstr https://github.com/jecolon/zigstr . (bias alert: I'm the author of both. :^D )

You might also be interested in dstep, a tool that can generate D bindings from C header files.

- C, Objective-C = https://github.com/jacob-carlborg/dstep

> its test blocks make unit testing trivial to integrate.

Again, D also has this:

https://tour.dlang.org/tour/en/gems/unittesting

  void main() {

It's a C lib, generating bindings is super easy https://github.com/jacob-carlborg/dstep

There is no need to maintain bindings that can be automatically generated, wich can easily get outdated if the C project is actively developped

Anyways, someone went a ahead and updated it: https://github.com/Soaku/raylib-d

Not quite as seamless as Zig, but dstep is an external program that leverages libclang to do the same thing (and generates a D module for you), as well as e.g., smartly convert #define macros to inlineable templates functions :)
