winit VS rust-sdl2

> Is this something Flutter doesn't do?

Flutter does do this (at least to some extent) on Desktop/Mobile. It attempts to create a hidden DOM tree for accessibility on web. Which generally doesn't seem to be thought to work very well.

> One of the most jarring experiences I have with Flutter Desktop was it lacked MacOS Emacs-style key bindings for text editing (ctrl-a, ctrl-e, etc.). Not sure if Dioxus solved this?

Ah, we're nearly there on that one. We have a PR [0] accepted into Winit (the underlying windowing library we use) which will allow us to access those events. We're just waiting on Winit to do a new release and then we can integrate it into Dioxus.

Hi! I’m Aloke, an engineer at Warp.

I’m really excited to share that Warp is now available on Linux! If you’re interested in trying it out, you can download Warp: https://warp.dev/

Building Warp on Linux was quite an undertaking. Warp uses a custom Rust-based UI framework that we built in house and renders natively on the GPU. To get Warp running on Linux, we built a version of our UI framework that supports winit [1] as a windowing backend. We also built a version of our renderer that uses wgpu [2]. Reducing complexity by using these well-supported, cross platform, frameworks let us bootstrap a version of Linux quicker than expected and should make it easier to build Warp for other platforms (like Windows).

Please let me know what you think! Happy to answer any questions, either about the product or about technical challenges.

This link: https://github.com/rust-windowing/winit has this code:

Have you seen the official example?

That's a bit shortsighted given that there is an active discussion about reducing the interior mutability.

I really need a file dialog for my ImGui-based project in Rust. I tried using this crate but it's wayyyyyyy too old. I also saw this but considering the date it was last updated and the look of the repo, it's not gonna work either. Also I maintain my own library for such things, but it's currently blocked by this issue. What options do I have?

In this case, I used the "A"GPL because this crate could feasibly run on the web. winit has a web backend. At the moment I don't support it (there's a PR that needs to land first), but in the near future it's not implausible that this crate could be used in a web environment.

It exists, but IMO it's not a good choice.

First of all, it doesn't support RenderGeometry or RenderGeometryRaw, which are necessary for high-performance 2D rendering. I doubt it will support any of the GPU stuff at this rate, as the geometry rendering is pretty much a prerequisite. Maybe both will land all at once, though. To wit, the relevant issue hasn't seen much activity: https://github.com/Rust-SDL2/rust-sdl2/issues/1180

Secondly, the abstractions chosen by rust-sdl2 are quite different from those of SDL2 itself. There seems to have been an aggressive attempt by the Rust library authors to make something more Rust-friendly, which maybe has made it more approachable for people who don't know SDL2, but it has IMO made it less approachable for people who do know SDL2. The crate gets plenty of downloads, so maybe it's just me.

I don't think that SDL and WGPU are really comparable. You'd be better off comparing SDL to something like Notan or even the SDL bindings for Rust. That said, SDL will have vastly more learning resources than Wgpu or Notan or any Rust alternative. If you know and like rust you can probably use the resources with the Rust SDL bindings.

Those are 3 very different libraries. Are you looking for something in the middle, or do you want all of the features you described? For what it's worth, there's SLD2 bindings for Rust https://github.com/Rust-SDL2/rust-sdl2

There's already a Rust binding for SDL2. See https://crates.io/crates/sdl2

nope. https://github.com/Rust-SDL2/rust-sdl2/issues/884 emscripten target won't work yet either.

it seems like what you are looking for is sdl2 bindings

Dude. It's literally at most 50 lines of code, the entire project. What kind of documentation do you expect me to write? The library I'm using is this one. I don't know why you'd need to know anything about it since it's purely something that can appear literally anywhere, it's part of the language.
