Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

We're building a browser when it's supposed to be impossible

Ladybird Web Browser โ SerenityOS LibWeb Engine with a Qt GUI
this is a qt frontend (definitely works on linux) for the serenityos browser engine, libweb.
this is a new, from-scratch implementation of both a modern html/css layout engine and a javascript runtime.
see https://libjs.dev/test262/ for ecmascript conformance tests.
the browser engine is far from finished but is able to display moderately complex pages like github.
it's always exciting to see a completely new web engine running in conventional environments like linux!

Show HN: We launched a new web browser
> Our JavaScript engine is decently mature, test262 score tracked here: https://libjs.dev/test262/
In a few years when they have achieved feature parity with Chromium or at least Safari we can discuss this again, but for now it's not ready for real life use.

LibJS JavaScript Engine
See https://github.com/linusg/libjs-test262 for an example, specifically the CMake files and `src/main.cpp`.
The separate website is just to have a nice & short link to the test262 graph and whatever else we'll put there eventually; and also because it's built/deployed in a slightly different way than the main serenityos.org website.

Looking for this. html + css rendering through wgpu.
If you were to implement this yourself, i'd look into either swash or cosmic-text for the text rendering stack (this is one of the things you really don't want to write from the ground up). For accessibility, AccessKit has quickly become the standard for communicating with crossplatform accessibility APIs in rust GUI. lightningcss (or its lower level counterpart cssparser) are both decent options for CSS parsing. Taffy handles some of what browsers offer for a layout engine, but is still being worked on.

JetBrains Noria
> Fleet relies on the Java AWT/Swing framework to get a window from an operating system, but it doesnโt use the Java platform for managing its GUI components besides one JFrame and JPanel on top of it.
This is a terrible decision that is going to bite them in the long run. Doing things this way makes it far, far more difficult to implement accessibility, and regulations on this are only going to get stricter.
Implementing accessibility for a framework like that would involve three separate implementations for three separate platforms and the need to interface with D-Bus, COM and Objective C, from Java. I imagine that the latter two would be particularly difficult, considering how bad Java's FFI support is. It's not just calling methods either, you'd actually need to implement your own classes that conform to the relevant COM interfaces / Objective C protocols. There are libraries that can help with this[1], but I don't think they would work particularly well for something as complex as a code editor.

fltk-accesskit: AccessKit integration for fltk
fltk-accesskit is an accesskit integration crate for fltk-rs, the gui crate. It's implemented as an external crate to allow for more experimentation before stabilizing the api, especially since fltk is at version 1.4.

We're building a browser when it's supposed to be impossible
Libraries for a lot of this stuff exist (albeit in many cases not very mature yet):
- https://github.com/pop-os/cosmic-text does text layout (which Taffy explicitly considers out of scope)
- https://github.com/AccessKit/accesskit does accessibility
- https://github.com/servo/rust-cssparser does value-agnostic CSS parsing (it will parse the general syntax but leaves value parsing up to the user, meaning you can easily add support for whatever properties you what). Libraries like https://github.com/parcel-bundler/lightningcss implement parsing for the standard css properties.
- There are crates like https://github.com/BurntSushi/bstr and https://docs.rs/wtf8/latest/wtf8/ for working with non-unicode text
We are planning to add a C API to Taffy, but tbh I feel like C is not very good for this kind of modularised approach. You really want to be able to expose complex APIs with enforced type safety and this isn't possible with C.

XUL Layout has been removed from Firefox
There are a number of up-and-coming Rust-based frameworks in this niche:
- https://github.com/iced-rs/iced (probably the most usable today)
- https://github.com/vizia/vizia
- https://github.com/marc2332/freya
- https://github.com/linebender/xilem (currently very incomplete but exciting because it's from a team with a strong track record)
What is also exciting to me is that the Rust GUI ecosystem is in many cases building itself up with modular libraries. So while we have umpteen competing frameworks they are to a large degree all building and collaborating on the same foundations. For example, we have:
- https://github.com/rust-windowing/winit (cross-platform window creation)
- https://github.com/gfx-rs/wgpu (abstraction on top of vulkan/metal/dx12)
- https://github.com/linebender/vello (a canvas like imperative drawing API on top of wgpu)
- https://github.com/DioxusLabs/taffy (UI layout algorithms)
- https://github.com/pop-os/cosmic-text (text rendering and editing)
- https://github.com/AccessKit/accesskit (cross-platform accessibility APIs)
In many cases there a see https://blessed.rs/crates#section-graphics-subsection-gui for a more complete list of frameworks and foundational libraries)

A new open-sourcing project launches!!! A declarative, compose-based and cross-platform GUI
Using HarfBuzz makes sense. But if you're looking for a pure-Rust alternative, I hear cosmic-text (made by Pop!_OS) is good. There's also AccessKit for accessibility.

Egui 0.20 Released
egui is an easy-to-use immediate mode GUI for Rust, and I just released 0.20. It's a big release!
There is now support for AccessKit (https://github.com/AccessKit/accesskit) which brings accessibility to egui (a first for an immediate mode GUI?).
There is also better table support, nicer keyboard shortcut handling, better looking text in light mode (still not great, but better).
See more in the changelog: https://github.com/emilk/egui/blob/master/CHANGELOG.md
