> we have almost half a million lines of modern C++ to maintain. ...We are actively evaluating a number of alternatives and will be adding a mature successor language to the project in the near future. This process is already quite far along, and prototypes exist in multiple languages.
What languages have prototypes and where can I learn more?
Whatever language you end up choosing, I hope it will be a memory safe one. Browsers' main purpose is to interact with the outside world, and they even have to run third party code (JS) all the time, so minimizing attack surface would go a long way I think
My favorite type of discussion! Language choice would seem super important long, long term and could provide long run advantage over other engines. Given the goals and philosophy of Ladybird zig seems like a complementary choice, and headed in the same direction in terms of community and freedom. And Perhaps just a sprinkle of something more verifiable than zig on the edges where correctness and safety are super critical. Have a look into tigerbeatle (https://github.com/tigerbeetle/tigerbeetle/blob/main/docs/TI...) and their philosophy.
I wonder if they are thinking Swift - their C++ interop is still pretty new and has a way to mature, but it’s designed for exactly this [1] (we should expect Apple to start doing it with WebKit and other big C++ projects, even perhaps LLVM).
