Describe your issue

I've tried to configure tailwindcss LSP for lsp-bridge and it seems to be getting through the configuration flow but never replies to completion requests:

{
   "id": 62852,
   "method": "textDocument/completion",
   "params": {
      "position": {
         "line": 10,

      }
   },
   "message_type": "request",

}

I never see a response.

The configuration sequence seems rather fine:

I tried a mix of configuration options for initialization but completion never picked up. What could be the obvious culprit? Can you suggest the best way to test it or a minimal configuration for that to work?

Other servers like Svelte, JS, Rust, etc work pretty fine and I'm surprised to be unable to get any progress with a tailwind. I checked the code of the server and VSCode plugin to figure out the configuration but with little fruit so far. Sadly, there is not much documentation on the server itself and it's quirks.

Am I missing smth obvious? Can you point me in a better direction?

I'll take a look at this soon — probably tomorrow. It does look like it's booted properly based on the fact that you're getting log messages though.

Would you mind providing these things:

• the contents of file:///umetra/someoneinmyhead/src/lib/components/NavBar.svelte (a simplified version is totally fine)
• The position of the cursor when you're invoking the completions
• The name, content, and relative location of your tailwind config file
• The exact version of Tailwind CSS you're using

@thecrypticace, thanks for getting back, I will provide all you ask. I activated logs for debugging reasons after failing simple attempts to integrate the tailwindcss language server. Having it for Emacs would be a blessing.

The NavBar is very simple:

  import Logo from './Logo.svelte';
  import ThemeToggle from './ThemeToggle.svelte';
  import TopMenuLinks from './TopMenuLinks.svelte';
  export let open: boolean;
  export let path: string;
</script>

<nav
  class="flex flex-nowrap bg-elevation-1 px-3 py-3 w-full sm:px-7 justify-between border-b-2 border-outline-variant"
>
  <Logo />
  <TopMenuLinks bind:path />
  <div class="flex gap-x-5 justify-end">
    <ThemeToggle />
    <HamburgerMenu bind:open />
  </div>
</nav>

Linking the issue I've created in the LSP bridge repo some time ago: https://github.com/manateelazycat/lsp-bridge/issues/882 The maintainer compiled a list of classes and created a completion backend out of them because of failing to make the Tailwind server work. I was blaming everything on configs but didn't find any clue after tons of trial, error, and debugging attempts.

[thecrypticace]

Hey — I just took a look and, you're definitely getting completion messages back from the LSP based on those messages, for example:

--- [11:06:33.482919] Record completion candidates (0) from 'tailwindcss' for file > NavBar.svelte
Eval in Emacs: (lsp-bridge-completion--record-items > '"/umetra/someoneinmyhead/src/lib/components/NavBar.svelte" '"" '() '(:line 10 :character > 118) '"tailwindcss" '("\"" "'" "`" " " "." "(" "[" "]" "!" "/" "-" ":") '("tailwindcss"))
{
   "jsonrpc": "2.0",
   "id": 10712,
   "result": null
}

---

This is a "successful" response to a completion request — it's just that the result is null. This is because the languageId being sent when you open the document is incorrect. The tailwindcss language ID is a custom language implemented for CSS files. Because of this it is trying to parse the file as CSS which it is not. The result is that it can't find any applicable completions for it and thus returns null.

---

You should use svelte for a Svelte file. For example, in the textDocument/didOpen request, I would change it like so:

{
  method: 'textDocument/didOpen',
  params: {
    textDocument: {
      uri: 'file:///umetra/someoneinmyhead/src/lib/components/NavBar.svelte',

      // BEGIN: I changed this line
      languageId: 'svelte',
      // END: I changed this line

      version: 0,
      text: "… clipped to make the snippet shorter …",
    },
  },
  message_type: 'notification',
  jsonrpc: '2.0',
},

If you do that, in response to the completion request, you'll get a response with actual data (clipped because it's a LOT of data):

{
  "jsonrpc": "2.0",
  "id": 10712,
  "result": {
    "isIncomplete": false,
    "items": [
      {
        "kind": 9,
        "data": { "_projectKey": "0", "_type": "variant" },
        "command": { "title": "", "command": "editor.action.triggerSuggest" },
        "sortText": "-00000000",
        "label": "*:",
        "detail": "& > *",
        "additionalTextEdits": [],
        "textEdit": {
          "newText": "*:",
          "range": {
            "start": { "line": 10, "character": 116 },
            "end": { "line": 10, "character": 116 }
          }
        }
      }
    ],
    // … omitted …
  }
}

Now I realize that you're using a plugin of some sort that actually communicates with the LSP — I'm not certain what settings you'll need to adjust to make sure it sends the correct language ID across the wire but that's the problem here.

Hope that helps! ✨

[artemkovalyov]

@thecrypticace, thank you, this helps. I'll try to amend what tooling sends and test it as you proposed. I'll get back with results when I have some:)

[artemkovalyov]

@thecrypticace, thanks again for the investigation. I tested and you were right about the language id. I see suggestions now and will try to fix the client implementation to respect it. You helped a lot to crack this puzzle.

[manateelazycat]

@artemkovalyov

Hi, thank you very much for contacting the author of Tailwindcss. I have fixed it in https://github.com/manateelazycat/lsp-bridge/commit/63e8d721d29c66d83ba1e62ccef113b16012a2bd

When the languageId field of tailwindcss.json is empty, lsp-bridge will be based on the file. The extension is dynamically sent to tailwindcss language server.

Thank you for your enthusiastic help
