sokol-samples VS femtovg

Zig currently doesn't allow chained designators and also doesn't allow to partially initialize arrays and fill up the rest of the array with default values.

E.g. the closest Zig equivalent to this C99 code:

https://github.com/floooh/sokol-samples/blob/b3bc55c4411fa03...

...is this:

https://github.com/floooh/sokol-zig/blob/a4b3c287fadd153a504...

...note how part of the initialization had to be moved out into "code".

There's a ticket about this here, but it's currently not high-priority:

This is a simple Pong-like I've written in Raylib compiled to WASM - https://wasm-stuff.netlify.app/pong

Source code is here: https://github.com/rrampage/skitter/tree/master/pong-raylib

It is fairly straightforward to get Raylib running in the browser. I used @flohofwoe's HTML shell file ( https://github.com/floooh/sokol-samples/blob/master/webpage/... ).

PS: also if shader functions could be directly defined "inline" in regular CPU code (and behind a special function pointer type), there would be no need for string literal shenanigans like this:

https://github.com/floooh/sokol-samples/blob/3f10c1a0620cec9...

(and shader compilation would happen during the regular build and would also generate regular compiler errors - with current toolchains that's only possible with a lot of build system magic)

I think something along those lines (rarely used...) was also given by the C++ Committee as justification why so much of the C99 designated init feature set was left out of C++20. But in reality, all C99 designated-init 'sub-features' complement each other nicely once you start using them. It's a great way for building 'data-driven' APIs.

For instance check out this call to create a 3D-API pipeline-state-object in C99:

https://github.com/floooh/sokol-samples/blob/ad9047e228a8441...

I'm using anonymous nested structs extensively for grouping struct items, but I consider the extra field name a feature, not something that should be hidden:

https://github.com/floooh/sokol-samples/blob/bfb30ea00b5948f...

(also note the 'inplace initialization' which follows the state struct definition using C99's designated initialization)

It's an STB-style single-file library, which means the implementation is in a separate ifdef-block from the interface declarations, this allows to compile the implemenentation in a separate source file (which can be a C file), and be used in different source files (which can be C++ files).

For example (using stb_image.h):

https://github.com/floooh/sokol-samples/blob/master/libs/stb...

C99 has made all that a lot easier, you can setup, initialize a struct and call the function taking a pointer to that struct all in one call:

https://github.com/floooh/sokol-samples/blob/89f5825ab5d3690...

The Win32 window system functions and D3D11 are actually very convenient to work with in C99, better than C++ actually.

Femtovg (https://github.com/femtovg/femtovg) which uses OpenGL to render

Congrats! I don't want to diminish the accomplishment, but have you seen femtovg? It seems like it's probably well-aligned with your needs.

I'm currently using femtovg for vector graphics in my games, and I would like to get into bevy by porting one of my game prototypes using it to bevy.

I use femtovg It's a simple vector graphics engine having all the important features you probably want from a 2D rendering engine: simple shapes, images, text

Before Power10 was done, IBM actually asked us Raptor users about proposals for useful machine code instructions to add to it. I replied that I’d like to have hardware UTF-8 de-/encoding but they wanted a more detailed proposal and I never got around to write it. I’m not even sure that this would be worthwhile, but I see UTF-8 de-/encoding everywhere in the code I write and would like it to approach memory read/write speeds.

I was very disappointed to learn that they had gone more proprietary with Power10 so I would not have been able to use those instructions anyway. What a pity!

In my actual code, I'm using a library called femtovg that is a Rust port of a C library for 2D rendering. But In the blog post I kept the example simple to keep it relevant for people who might want to use Web Workers + WASM for other things; didn't want to get hung up on femtovg for someone who had never heard of it. As you say, if you all you need to do is basic 2D manipulations of a canvas that are supported by the native API, then you likely don't need WASM.

You guys should also check out the femtovg project, a 2D rendering API that sixty fps relies on.

It's a decent starting point for trying to build your own toolkit.

I have recently added a wgpu backend but for now it lives in my fork https://github.com/adamnemecek/femtovg

run the demo with `cargo run --example wgpu_demo --release`.

Also join the femtovg discord https://discord.gg/V69VdVu

I'm involved with the femtovg project. We are definitely looking for contributors. Join the discord channel.

It's not a GUI framework but I'm involved with this project called femtovg, it's a Rust nanovg port. I've recently added a wgpu backend. Run the demo with cargo run --example wgpu_demo --release. Some people have been using it for their own UIs, e.g. tuix. I think that you should consider rolling your own GUI toolkit, it's not that bad and you'll appreciate the control.
