Zig Software Foundation 2024 Financial Report and Fundraiser
Myself and many others are betting on Zig in major ways, I truly think it has a bright future ahead.
In spare time, myself and a few others are working on a game engine in Zig[0], and the Zig core team has been very receptive to addressing issues our project faces and supporting us.
Others are working on pixel art editors[1], open source 2D RPG games[2], there's a group of independent folks working on a 3D massive immersive sim game[3], a group working on making Zig an amazing language for micro-controllers[4], etc.
Please consider donating $5-10 a month to the ZSF! They are a great group of people, and it has so many knock-on effects for others in the FOSS community. :)

DevDocs
I don't know if there's anything better than a zip. For our website[0] which includes a bunch of docs for our game engine, Zig packages, etc. we just offer a link "offline version of this site" in the footer which is an ~80MB zip file.
I think the challenge with zip files is.. do you want all the images? do you want all versions of the docs, or just a specific version of the docs? It's hard to tailor the zip to the user's desire. But zip still seems to be the best.

New Béziers from Math
Cool to see others working on this problem. I hope more people do.
Funnily I've seen a lot of programmers and math folks who express how truly, genuinely beautiful Beziers and the math behind them are. But I've never met an artist or graphic designer who didn't express some deep frustration at Bezier controls and how hard they are to work with.
There are even games[0] which make a mockery out of how hard Bezier controls are to use, where the game is purely using the controls.
Controls are just one side of the problem, in my view; the other side is that cubics are terrible for GPUs, they don't understand them - and I believe many of the best 2D graphics libraries today are not even fully GPU accelerated, e.g. Skia. There are folks working on compute shader-based approaches, where we try to shoe-horn this CPU-focused algorithm into GPUs and pray - but it still isn't really suitable.
The controls suck for artists, and the math sucks for GPUs. This is only true of cubics, if you restrict yourself to quadratics (although that brings other challenges), both the control issue goes away (you can just click+drag the curve!) and the performance issue goes away (quadratics are triangles, GPUs love them)
That's the summary of the talk[1] I gave at SYCL'22. In that talk, I didn't have time to present the downsides of quadratics (which are real) - so if you watch it please keep that in mind - but my overall point I think is a solid one: the controls suck, and GPUs can't handle them.
The only reason we stick with cubics in its current form is because of SVG, compatibility with existing tooling, etc. But isn't it crazy? We have new bitmap image formats all the time, and so few vector graphics formats.
In Mach engine[2] we're continuing to explore this space, end-to-end, from author tooling -> format -> rendering. I'm not claiming we have a perfect solution, we don't, but we're at least thinking about this problem. Kudos to the authors of this article for thinking about this space as well.

Learn WebGPU
Zig fits pretty naturally here too. We've got ~19 WebGPU examples[1] which use Dawn natively (no browser support yet), and we build it using Zig's build system so it 'just works' out of the box with zero fuss as long as you grab a recent Zig version[2]. No messing with cmake/ninja/depot_tools/etc.
WASM support in Zig, Rust, and C++ is also not equal. C++ prefers Emscripten which reimplements parts of popular libraries like SDL, for me personally that feels a bit weird as I don't want my compiler implementing my libraries / changing how they behave. Rust I believe generally avoids emscripten(?), but Zig for sure lets me target WASM natively and compile C/C++ code to it using the LLVM backend and soon the custom Zig compiler backend.

Zig for gamedev?
Two game frameworks in the making: https://github.com/michal-z/zig-gamedev & https://github.com/hexops/mach
We're building Mach which aims to be competitive with Unity/Unreal/Godot in spriti, but super modular / let you pick and choose which parts to use or build yourself.

Zig Build System
Zig calls clang to compile C code. This doesn't add a new dependency since Zig already depends on LLVM. In the future when Zig doesn't depend as much on LLVM, there might be a reason to use a C compiler written in Zig (e.g. https://github.com/Vexu/arocc)

Zig 0.9.0
> Does this mean that y'all are open to the self-hosted compiler supporting CPU architectures unlikely to ever have LLVM support?
Yes! We won't block 1.0 on the quality of the less mainstream targets, but that's what the tier system is for - to ship a compiler that has varying levels of quality for various targets, while communicating clearly to users what kind of experience they can expect for each one.
SuperH patches are absolutely welcome.
> how is zig cc anticipated to work with a self-hosted Zig? Will there be a dependency on clang [...]?
The main distribution of Zig will be LLVM/Clang-enabled. However it is already possible to build a version of Zig that does not have these features enabled. In such case, compiling C, C++, and Objective-C code will result in an error.
However, the arocc project[1] is emerging, which, depending on a combination of how much funding ZSF gets and how much enthusiasm the unpaid contributors working in their spare time have, is looking like a promising C frontend that would be available even without LLVM/Clang. It is C only, however, with no intention of compiling C++ or Objective-C.
> would zig cc support the planned C backend?
As it is currently implemented: no. Zig invokes clang to turn C source code into object files.
However, with the arocc frontend above, this would be converting the C source code into ZIR (or perhaps AIR), which could then be lowered with any of the backends, including the (partially complete) C backend. In such case, the C output would look drastically different than the input. It would look more like an IR than natural C code that a human would write.

[Rust advocates] demean software that's not memory safe the way that politicians use their words to sow anger. C has won, and Rust blew it's shot aiming at C++ instead.
Implementing only the language part takes like 10k LOC.

Adding ANSI C11 C compiler to D so it can import and compile C files directly
> 9. Without a C compiler, we're stuck with, wedded to, and beholden to libclang.

This is a really insightful point. I had to learn this the hard way :)
We might follow your lead on this, as we have done with so many other great ideas implemented in D.
Ironically, Vexu started from the other side as you, with the preprocessor mostly done, but the backend left to-do: https://github.com/Vexu/arocc
One thing that might make libclang worth the cost, however, is its ability to compile C++ code as well. On Zig's end of things, all we have to do is provide libcxx, libcxxabi, libunwind, compiler-rt, and linking, and then libclang is really pulling a lot of weight by compiling C++ code into object files. Sadly this ability is just too useful in practice to ignore. For example, LLVM itself is C++ so if Zig wants to be able to bootstrap itself, it needs this capability.
Still, I think your maneuver here is the best long-term approach to tackle this problem, and I imagine as time goes on we'll start to migrate towards D's solution here. Maybe someday the Zig distribution that does not have LLVM extensions enabled will be the more popular one!
I'll be watching the evolution of this new feature in D with great interest!
