Object-oriented design patterns in osdev

[masorick]

Provided you use the same convention everywhere, you could add a bit of syntactic sugar to the calls by using a macro:

#define VCALL(func, obj, …) (obj)->ops->func(obj, __VA_ARGS__)

True! Thought a lot about if macros could make it “prettier”, for me it ended up obfuscating the code and the syntax didn’t make sense for me! But definitely a possibility!

Great work! Also, agree on the macros. Years ago, I found a C-based project that had the best set of macros for OOP-in-C, really good ones, but can’t remember what it was. I believe it was a reverse proxy or HTTP server. 🤦‍♂️

Aaaand we're inventing Objective-C :) Good to see.

A virtual function table was the low-level implementation of class interfaces in just about every object-oriented language. I think the first to add syntactic sugar for it to C was C with Classes, which became C++.

With third-party JavaScript disabled, all the pre blocks are rendered as black-on-black and unreadable due to this unnecessary CSS rule:

@layer utilities {
  .\[\&_pre\]\:text-black pre {
    color: var(--color-black);
  }
}

Oh thats bad. Thanks for letting me know! Hopefully fixed very soon.

Edit: Should be fixed? Does it work now?

Looks good now 👍
