Being able to iterate on games and UIs while running a @bevy.org app with dioxus hot-patching is MENTAL. Love it so much!

Thanks! So the square map is a binary tree that bottoms out in sorted vectors of some max-size? (A picture would help your article a lot 🙏)

I think a comparison to a B-tree is warranted

Finally, we've improved text rendering (again!). Especially light mode looks a lot better. Before/after:

SVG support has been greatly improved. We now have pixel-perfect scalable vector graphics. Yay :)

On a related note, the next Rerun release switches all its icons to SVGs ;)

We've completely rewritten popups in egui, with `egui::Popup`, which now powers tooltips, context menus, normal menus, combo-boxes, and everything else that, well, pop up :)

It's very powerful yet ergonomic

egui::Atom is the new, indivisible building block of egui (hence the name). It lets you mix images and text in many places where you would previously only be able to add text.

Atoms is the first step towards a more powerful layout engine in egui - stay tuned!

egui 0.32.0 has been released!

This is a big egui release, with several exciting new features!

* Atoms are new layout primitives in egui, for text and images
* Popups, tooltips and menus have undergone a complete rewrite
* Much improved SVG support
* Crisper graphics (especially text!)

Anyone wants to work on some clippy lints? :)

This is a BIG undertaking and will take a while to get done. My startup, Rerun, is sponsoring the PR author Valadaptive in her ongoing work.

Exciting news for egui: there is a draft branch for switching the text handling to Parley, which will bring support for color emojis, right-to-left text, access to system fonts, and much more! github.com/emilk/egui/p...

Also it just keeps on coming today…

emilk @ernerfeldt.bsky.social · Apr 13

It’s only once a year or so, but when it happens you can’t mass-report it, so you need to either spend hours reporting each issue individually (no thanks) or ten minutes closing all as ”not planned”. But then the issues remain forever, and goes unreported.

emilk @ernerfeldt.bsky.social · Apr 13

@github.com Please step up your anti-spam game. Having to manually mark hundreds of issues as "Not planned" is not a fun way to start my Saturday 😡

I use it to keep track of the libraries dependencies, to make sure it doesn't explode. I also use `cargo deny` to ensure there are no duplicates in the dependency tree.
And if someone makes a PR to add a new dependency, you directly see all the transitive dependencies it pulls in.

Hot take: All Rust repos should have Cargo.lock in git together with a `.gitattributes` file containing:

Cargo.lock linguist-generated=false

This makes the diff of Cargo.lock show up in GitHub PRs
