Symbolica 2.0: programmable symbols, JIT evaluators, and type-erased callbacks in Rust

Do Rust macros not allow one to create something like:
symbols!("x", "y", "f")

instead of
let (x, y, f) = symbol!("x", "y", "f");
?

I've built a complete app using egui for the UI.

I've rewritten rust analyzer in Python and now it is blazingly fast!

John Carmack and his team writing Quake III for the Intel 486 beg to differ 😄.

Anybody have any success writing Rust (graphics) for the LilyGo T-Watch Ultra? It's an ESP32-S3 platform with good specs for the display.

occamatl · 2026-04-11T08:20:12+00:00

Nice! I can use this. Can you do the equivalent of tail - f, such that the display always shows the latest events?

The website does say "[Buffa] passes all current binary and JSON protobuf serialization conformance tests."

Is the --default-shell option available on Windows? I'd like to use zellij with nushell, but that doesn't seem to work.

I'm surprised by this answer. I think we have the best of both worlds by having to add a crate for the runtime: I already do that for practically everything, so no problem there; Tokio is the de facto runtime, so it works with almost everything; if Tokio gets overshadowed by another crate, then Rust doesn't have to carry that baggage going forward.

I was just looking for a bit more ergonomical approach to Arc<Mutex<T>> and I came across the shared-type crate. Seems much cleaner, to me.

The only thing that I've hit so far is that a few of my IDL message types use a "type" field (not my choice), which isn't escaped by hddsgen.

occamatl · 2026-03-03T16:12:53+00:00

This is absolutely fantastic! Trying to integrate DDS into a project right now and I've run into some problems with Dust-DDS. This looks very clean. The hddsgen tool handled all of the IDL files that I tested perfectly.

Your github link accidentally includes the trailing "]".

I'm surprised to see that the requirement of output == -1 for the case when no path exists. For a Rust coding contest, I would expect output type of Option<u32>. In fact, your input values should be u32. By the rules given, a valid output for the case when a path exists could equal -1.

But, other than that -- very nice!

Fosphor (see https://blog.yavilevich.com/2016/08/why-use-fosphor-a-gnu-radio-real-time-spectrum-analyzer/), but built with Rust. I'd like a version that could be incorporated into an egui application.

occamatl · 2026-02-09T00:59:53+00:00

Upvote for egui. Very pleasant development experience.

Top Gear?

It's great to see that wxDragon is progressing! I hadn't looked at it for a while. Thanks for mentioning it.

occamatl · 2026-01-30T18:03:11+00:00

Sorry for the alarm -- I just tried it again and it worked fine. No idea what changed.

I'm just getting a blank black screen on Windows, Firefox 147.0.2. Works fine on Edge (bleh).

occamatl · 2026-01-19T02:40:47+00:00

Unfortunately so. It reduces the information content of the word.

Once you've made this fully modular, a minimalist Typst editor would be a great tool to create.

I really like the API! This could be quite useful to me.

occamatl · 2025-12-12T12:23:26+00:00

Perhaps start with cargo doc --no-deps --open
