Maybe you need to add an "(in Rust)" to all these sentences? Sure there are C++ frameworks, but they probably wanted a pure Rust UI framework? My 2 cents: it's nice to have smooth rendering in your editor, but I'm currently mostly using a Java-based IDE (IDEA family), and it's responsive enough for my taste. If I were to use the current prototype of their editor, I'm afraid the usage of fixed-width fonts all over the place (which I assume can be fixed, but may also be due to constraints of the UI framework?) would probably bother me more than the 120 FPS UI would impress me (assuming that I had a monitor that was fast enough, which I don't). On the plus side, it sounds like they support sub-pixel rendering - if that's the case, kudos to them!

Not true, even if you add Rust. egui was released earlier: https://github.com/emilk/egui https://github.com/emilk/egui And egui isn't tied to Apple proprietary frameworks.

  Afaik egui isn't doing any kind of the fancy GPU based 2D graphics this blog post is about though.

    It uses glow, GL on whatever, so OpenGL when it exists.
    - littlestymaar 4y ago
      That doesn't mean it's doing any kind of GPU acceleration of 2D graphics. Given that they don't talk about it in the README, I'm pretty sure they don't.

        I use egui. The library itself is agnostic but relies on backend libraries for rendering, all of which (or at least the official ones) render on the GPU.

    have a look at what egui creator (and his team) been doing with rerun [0] Egui seems well suited to render even tens of thousands pointcloud with wgpu backend. [0] https://www.rerun.io/ https://www.rerun.io/

      Rerun dev here :). Yes, we're using egui with its wgpu backend! As someone else pointed out it is backend agnostic - it essentially generates triangles & textures in GPU friendly way and passes those down to a backend implementation. All the visualizations like the 3D scenes with point clouds etc. are rendered with our open-source in-house renderer ("re_renderer") which itself is then passing wgpu surfaces/commands to the egui wgpu backend that composites everything together then.

Hey rob74! Antonio here, author of the post. Zed is not constrained to use fixed-width fonts and supports all kinds of fonts, monospaced and variable-spaced alike (ligatures and contextual alternates included). Even though we use a glyph atlas, we rely on CoreText for shaping and rasterization (rendering sub pixel variants as well). In practice, this means that text is indistinguishable from a piece of text rendered by the operating system.

  Does your framework have any accessibility features? I'm a screen reader user and having responsive UI is wonderful as far as it is accessible at all.
