Misc notes

It would be really useful to have support for the Julia language (https://julialang.org). Not much to say except that it's one of the rising stars in the world of scientific computing. I used it for research at uni and now I use it at work.

Using Julia also often means using Unicode chars such as ≠ through typing \ne and then Tab, it might be worth checking out https://github.com/JuliaEditorSupport to see what users are accustomed to.

Zed could easily become the editor of choice for Julia - would love to see this happen

[gbaraldi]

It would be lovely to have julia support on zed.

Friends, I will support my colleagues above: need to support Julia and thereby cover a large mass of people with a perspective for the future; especially Julia is an ideological relative of Rust

[hovsater]

Work have begun to enable Zed to be extended with other languages. Unfortunately, I don't have an estimate on when this will be available for the general public. Stay tuned. 🙂

It would be amazing to have Julia support on Zed! thanks zed team i really enjoy using it!

[3f6a]

If Zed supports Julia I will definitely try it out!

[Robert-j7]

Patently waiting. Can we send snippets to repl as well?

[3f6a]

Perhaps zed-industries/zed#6690 (Zig support) can serve as inspiration. I would guess a similar approach would work here?

[3f6a]

Also, Haskell: zed-industries/zed#6786, Gleam: zed-industries/zed#6733

[alstat]

With Haskel, Gleam, and Zig recently added. I hope Julia will be next. Looking forward to this.

[whiterock]

Anything happening here? (Im)patiently waiting :)

Zed is crisp and thrilling. Can't wait to see Julia Language support on Zed.

For anyone interested in starting from zed-industries/zed#8133 to build an extension, there is a blocker that the tree-sitter grammar requires too much memory to build to WebAssembly (see tree-sitter/tree-sitter-julia#124).

[piechologist]

tree-sitter build-wasm runs fine on an Ubuntu VPS with 128 GB RAM. The compiler just needs 57214472 k resident size (cough) and 13 minutes. So, a 64 GB machine may be not enough. The resulting julia.wasm is 9.2 MB big (compare this to 451 kB for the R grammar).

@JosephTLyons @maxdeviant Is building that beast too much for your workflows here or should we just try?

Im still struggling to understand if *.wasm files are architecture independent. Can I use the julia.wasm built on Linux x64 on an Intel Mac?

[MultisampledNight]

(fwiw yes WASM files are architecture independent. WASM is an architecture of its own, and needs a runtime to actually evaluate it. In the case of the web, this runtime is e.g. the browser)

Sheesh, I wonder why it is so resource-intensive?

One thing that you could try is adding it as a dev extension in Zed and let Zed build the Wasm file, as we use a different approach for building the Wasm grammar (calling clang directly instead of going through the tree-sitter CLI).

That won't help, a single clang process consumes all that memory.

[maxbrunsfeld]

This problem should be solved in the latest version of Tree-sitter-julia, due to some improvements to Tree-sitter's code-gen.

Compiling the Julia parser to WASM is still a little bit slow, but no problem to do on our CI machines. If anyone wants to develop the extension, it should be very straightforward.

[piechologist]

I've got the Tree-sitter part (highlights, outline, etc.) working locally. Looks great so far! I'm not into the LSP stuff though.

@Pangoraw: Are you interested in putting it together? I'd be happy to contribute to the queries (I had to make some adjustments for the updated grammar). Alternatively, https://github.com/JuliaEditorSupport might be a good place to collaborate?

Thank you, the wasm parser now builds smoothly on my 8Gb machine!

@piechologist great that you have the grammar working with the updates!

I have a version with LSP here https://github.com/zed-industries/zed/compare/main...Pangoraw:zed:zed_julia?expand=1 (i had to comment some grammar queries), I will ask on slack to get a repo under https://github.com/JuliaEditorSupport as that would be the best way to collaborate.

[3f6a]

That's great news. Excited to try Julia on Zed.

[maxbrunsfeld]

That's great to hear @Pangoraw, let me know if you need help. I'm happy to see Julia supported.

[rawjeev]

Lovely! Will try zed with Julia support.
