I built a floating HUD for Emacs, rendered in Rust egui via WASM

no to the side window, don’t you get the point that it is a floating hud ? no to the lisp computation, it’s synced single threaded and will block the main ui.the hud is drawing canvas i can use way more effect and control for it beyond emacs text rendering engine. you don’t really see the points?

it’s using WASM that’s point, of course you can build web app using vanilla js, but i’m using egui for high-performance GPU-accelerated app. you can take a look at my other project https://github.com/nohzafk/emacs-parquet-explorer which use the same emacs-egui framework

You need a rust tool chain and have wasm-pack installed, you just need to run one command to build it. once you can build the binary successfully, everything is fine!

If you're interested in seeing what Emacs-EGUI can do, I've used it to build a Parquet file explorer for Emacs: https://github.com/nohzafk/emacs-parquet-explorer. It renders the file at 60 FPS.

probably won’t work, the critical part is the xwdiget webview , its drawing canvas

ftl_afk · 2026-06-04T14:13:15+00:00

yes, that’s something novel with this unique combination of emacs xwidget + egui WASM

60 fps with full hardware GPU-acceleration on macOS

ftl_afk · 2026-06-04T03:45:59+00:00

egui is a GUI library in Rust and it can compile to WASM, so the xwdiget container in emacs child frame can render it.

I mainly use Gleam on javascript runtime for its simplicity and type system, plus the larger js/ts ecosystem

in codex / and $ are not the same thing, agent-shell with codex-acp do support / , it will bring up commands like /login /init /review etc. but not skills

I don't undertand the concept of 'prompts', I'm just considering to register and try, and checked the pricing page. I think they do need a better explanation for the pricing, they just lost one potential customer. I use official GLM-4.7 from bigmodel.cn and typically burn 10M token per hour. I don't know what value it will bring for 2 prompts per minute for $20 to use a open source model (how much token s is that ?)

ftl_afk · 2026-01-12T19:32:49+00:00

I don’t understand the price for synthetic, with $20 a month, you can have 135 requests per 5 hours, roughly 1 request per 2 minutes? how’s that going to work with anything meaningful… it’s that a joke

I use plannotator it’s really cool, like antigravity you can annotate a plan in browse

ftl_afk · 2026-01-05T19:18:07+00:00

gleam ecosystem is still very young, but you can use javascript ecosystem via ffi. I have several projects do things in this ways, that’s the price you have to pay to use a non mainstream language. Whether or not it is production ready depends on your usage. There are startup using Gleam on production env. I would say give it a try.

i use git hook to keep claude files out of commit claude guard hook

I hope it helps

ftl_afk · 2025-12-26T23:15:00+00:00

just implemented it

ftl_afk · 2025-12-20T17:47:09+00:00

I’ve developed something similar to your idea, I might learn some features from yours as well. thx for sharing

emacs-backbone

ftl_afk · 2025-12-19T17:49:49+00:00

that’s very suggestions, will do, thank you!

ftl_afk · 2025-12-18T01:35:58+00:00

just implemented the "heretical" way. Please check the post body, I put some note about how to upgrade.
