zed-editor codebook for Latex files doesn't support suggestions

[Yeshey]

In zed editor, while in other languages CTRL + . gives me suggestions for the correct word, in latex I don't get any.

And I'm getting [codebook_lsp::lsp] DEBUG: Document identified as type None from None:

Hey! Thanks for the logs. Do you have a minimal example file where this issue happens?

[Yeshey]

Heyo!

For sure!

These are my zed editor settings.json rn: (at cat ~/.config/zed/settings.json)

{
  "auto_install_extensions": {
    "codebook": true,
    "latex": true
  }
}

I just created a new folder and created a .tex file inside:

% Funktion to validate user inputt
\documentclass{article}
\begin{document}
This is a missspelled word.
\end{document}

Strangely enough, no squiggly lines at all were appearing at first, I created another javascript file inside to test:

// Funktion to validate user inputt

And after saving that, javascript spell checking worked perfectly and when I got back to the .tex file squiggly lines started appearing as well.

But I still only get suggestions (by pressing CTRL + . on top of the misspelled word) for the js file:

But not for the latex one:

[Yeshey]

@blopker

I can also reproduce it without latex extension at all, so cat ~/.config/zed/settings.json has:

{
  "auto_install_extensions": {
    "codebook": true
  }
}

That's the only relevant config, so edited the redundant configuration out of my above response

[blopker]

Interesting, thanks. A few more pieces of info will help though: can you check what version of the Zed Codebook extension you have via the Zed extension menu?

Also, any global or project codebook.toml files you have would be good to see

wow, seems like I'm a bit behind 😅

[Yeshey]

Let me see if I can install the latest version

[Yeshey]

That fixed it 🤦 🤦 🤦
I'm in v0.2.4, not even the latest one.

Sorry for wasting your time 😅 🙏, I should have remembered to check the versions

[blopker]

No problem! That behavior did seem like an outdated extension issue, so I wanted to make sure.

I am curious, do you have an idea why Zed wasn't updating automatically? Maybe the auto update isn't as robust as I thought. I may need to do some kind of check on startup.

In any case, people will find this issue in the future and it will hopefully help.

In my case I was in zed-editor version 0.189.5, and it wasn't letting me install newer versions of codebook because it was saying Incompatible with any version of codebook higher than v0.1.8. When I updated to zed version 0.211.6 it automatically set the codebook extension to version v0.2.4 witch is the latest one available in the Zed extension menu. I'm seeing here in the repo the latest one is v0.3.18 but that's about all that happened 🙃
If I can help with anything else let me know! And thanks a lot!

[blopker]

I see. Yeah, the way extensions work, it's hard to keep them working with old Zed versions while also keeping the extension dependencies up to date.

Also note that v0.2.4 is the latest extension version (which is located here https://github.com/blopker/codebook-zed). The Codebook server is v0.3.18, which gets downloaded/updated by the extension. Sadly, it's a common point of confusion for people.

Anyway, let me know if you have any more issues!

[Yeshey]

Cool, no problem, thanks a lot! :)
