Alf Richter (Feb 04 2024 at 22:57): Alf Richter (Feb 04 2024 at 22:57):Short info: I'm started to integrate the roc tree-sitter and the lang_server into the Zed editor code base, after forking and fixing the tree-sitter from https://github.com/faldor20/tree-sitter-roc to work with rust. I'm in the middle of adding the lang server and testing the stuff. BTW. I'm a total rust and zed newbie :sweat_smile: ...
Isaac Van Doren (Feb 04 2024 at 23:24):Sweet!
Alf Richter (Feb 05 2024 at 12:57):image.png
First working version, zed needs to build from sources of my PR:
https://github.com/h2000/zed/tree/add-roc-lang%237378
Hannes Nevalainen (Feb 05 2024 at 22:14):Amazing :) hope it will be accepted so I can ditch vscode for my roc adventures :)
Alf Richter (Feb 05 2024 at 23:34):You can build it from my branch above in the meantime (rust and Xcode needed)
Alf Richter (Feb 06 2024 at 17:07):The official build of zed with roc will take longer, they only want main stream languages directly in their code base, and will provide a plugin api for the others => which is a very good idea for both sides :) . Thats why they closed my PR. I'll port our roc lang stuff to the new plugin api, when they publish these.
(https://github.com/zed-industries/zed/pull/7379)
Alf Richter (Feb 06 2024 at 17:09):In the meantime build zed from source is a option. When I have time I'll try generate an unoffical zed binary....
Alf Richter (Feb 08 2024 at 13:36):Here the ticket for the language extension plugin infrastructure in ZED https://github.com/zed-industries/zed/issues/7096
Luke Boswell (Apr 21 2024 at 04:11):@Alf Richter looks like the've just merged that language plugin extension :smiley:
Luke Boswell (Apr 21 2024 at 04:12):https://zed.dev/blog/language-extensions-part-1
Eli Dowling (Apr 21 2024 at 21:32):I took a little crack at it... because I didn't see this thread :sweat_smile:
https://github.com/faldor20/zed-roc
but zed is pretty broken on my linux laptop so I can't really test it sadly
Eli Dowling (Apr 21 2024 at 21:39):I also found your extension @Alf Richter which is a bit further along than my attempt.
I took a look, I think you just need to update the command to run the roc lsp to "roc_langauage_server" and update the tree-sitter queries and commit Id. :)
Alf Richter (Apr 21 2024 at 21:56):@Luke Boswell, cool finally.
@Eli Dowling thanks for looking into it. I'll continue with it in the next days and report back here, and will look into your attempt as well :)
Alf Richter (Apr 24 2024 at 15:01):Here my current progress:
https://github.com/zed-industries/extensions/pull/432
Alf Richter (Apr 27 2024 at 13:49):The extension for Zed is now working (syntax highlighting + language server) and pushed to zed/extensions github.
Until it is fully integrated with zed, it can be used:
git clone https://github.com/h2000/zed-roc
zed: extensions with the button 'Install Dev Extension' (top right corner). Alf Richter (Apr 27 2024 at 13:51):
Richard Feldman (Apr 27 2024 at 14:16):awesome, thanks so much for making this! I've been using Zed for Rust development and I'm stoked to use it for Roc too now! :heart_eyes:
Agus Zubiaga (Apr 27 2024 at 14:43):Same! That’s awesome
Bryce Miller (Apr 27 2024 at 22:14):Hey @Alf Richter, did I perhaps miss a step? When I open the directory with “load dev extension”, a target directory appears with a wasm build, but Zed doesn’t register the extension.
Alf Richter (Apr 28 2024 at 15:59):The error reporting inside Zed for extensions is not really present at the moment.
See my question in github zed extensions roc PR:

Alf Richter (Apr 28 2024 at 16:03):Please take a look at the Zed log file:
less ~/Library/Logs/Zed/Zed.logZed: open log Alf Richter (Apr 28 2024 at 16:06):(deleted)
Bryce Miller (Apr 28 2024 at 17:26):I'm using Zed 0.132.3. MacOS 14.4.1.
Bryce Miller (Apr 28 2024 at 17:26):Thanks for reminding me to check the log. I am seeing a failure to link with clang

Alf Richter (Apr 28 2024 at 18:14):@Bryce Miller: I had similar errors about apple-m1 before, my solution was to reinstall my rust installation:
e.g. (or using an other way)
rustup self uninstall
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Reinstalling rustup and the stable toolchain fixed the problem! Thanks!
Alf Richter (May 02 2024 at 07:15):Roc has (in Zed 0.133.5) an officially zed extension now:
image.png
Alf Richter (May 02 2024 at 07:24):I did not found a good zentral place to add zed to the official editors list. For the best onboarding experience I'd expect it near/in the installation guide? Should I make a PR to update the GettingStarted.md in roc-lang github, and add an editor section with links to all editors? Or here https://www.roc-lang.org/install ?
Eli Dowling (May 02 2024 at 10:42):Go ahead and make a pr to that page :)
Richard Feldman (May 02 2024 at 11:07):amazing, thank you so much for making this happen!!! :heart_eyes:
Alf Richter (May 02 2024 at 17:05):My PR for adding an editor section to the getting started readme is ready for review:
https://github.com/roc-lang/roc/pull/6706/files?short_path=15e1597#diff-15e15974446c709f371ea5c1041c2a5fb944f3f8de6ddfbae91a05ae93041255
Richard Feldman (May 04 2024 at 23:56):I found a funny bug in the grammar: it doesn't know crash is a keyword, but it does know as is a keyword, resulting in...
Screenshot-2024-05-04-at-7.55.54PM.png
Richard Feldman (May 05 2024 at 00:00):also it doesn't know about import and exposing but that's not surprising given how recently the PR for those landed! :big_smile:
Eli Dowling (May 05 2024 at 11:41):I'll take a look at updating to the new suntax in the next week.
If I could get a heads up about when a new syntax is coming a week in advance I should be able to co-ordinate to get a change in so people have an immediate upgrade path :)
Alf Richter (May 08 2024 at 13:12):@Anton
I've created a new PR to update a second place for new editor exts (this page is linked to the roc website directly). Why do we've two different install pages :) , the tutorial pages links to both?
https://github.com/roc-lang/roc/pull/6735
Anton (May 08 2024 at 13:29):Thanks @Alf Richter, I'll try to take a look today :)
Luke Boswell (May 08 2024 at 14:08):Is there a way to turn off the auto formatting in zed for roc files?
There's a few issues that are kind of a pain rn. At some point I'd like to submit a fix for them, but if I can just turn of the auto formatting for now that would be nice.
Agus Zubiaga (May 08 2024 at 14:18):Yes, you can have language-specific config, like:
// ...
"languages": {
"Roc": {
"format_on_save": "off"
},
}
// ...
Thank you
Agus Zubiaga (May 08 2024 at 14:29):With Zed, I'd also recommend using a monospace font for the UI, because they use the UI font for LSP diagnostics and things don't line up otherwise.
Agus Zubiaga (May 08 2024 at 14:31):Ideally, they would use the buffer_font_family for diagnostics or have a distinct setting that defaults to it, so you can still use a proportional font in the rest of the UI.
Richard Feldman (May 08 2024 at 15:00):@Agus Zubiaga can you open an issue on zed for that?
Agus Zubiaga (May 08 2024 at 15:35):Done: https://github.com/zed-industries/zed/issues/11564
Agus Zubiaga (May 08 2024 at 15:46):It’s a little subjective because ideally our diagnostics shouldn’t be trying to highlight things that are already visible in the buffer.
Agus Zubiaga (May 08 2024 at 15:47):However, I still think monospace diagnostics allow more flexibility.
Anton (May 10 2024 at 17:36):Why do we've two different install pages :) , the tutorial pages links to both?
Thanks for bringing this up @Alf Richter. I'm in favor of avoiding duplication and putting all getting started/install stuff on the Roc website only. Anybody have concerns with that?
Andrea Bueide (Sep 09 2024 at 04:50):does anyone know how to build the roc extension on nixos? am trying to learn how to contribute on zed extensions, can't find anything about building on nix though
