VS Code Vim settings

I'm using Vim 9.0.472 and the vim-lsc plugin. My vimrc config is:

let g:lsc_server_commands = {'html': 'tailwindcss-language-server --stdio'}

Describe your issue

I have a single index.html file in my Tailwind project directory. Tailwind's CLI works fine because it detects my classes and generates the stylesheet as expected.

I want to be able to (a) autocomplete Tailwind's classes and (b) hover over a class to see the actual CSS it corresponds to.

I assume the language server is the best way to achieve this? Or is there a way to generate a stylesheet with every possible Tailwind CSS class, which I could then use a source for autocompletions?

Anyway, when I open my index.html in vim, I see the error message No workspace folders found, not initializing.

I believe this error comes from here:

tailwindcss-intellisense/packages/tailwindcss-language-server/src/server.ts

Lines 1610 to 1613 in 3aafffe

	if (!this.initializeParams.rootPath) {
	console.error('No workspace folders found, not initializing.')
	return
	}

Logging shows me that vim-lsc sends this to the language server:

{"method":"initialize","jsonrpc":"2.0","id":1,"params":{"rootUri":"file:///path/to/my/project","capabilities":{"workspace":{"configuration":true,"applyEdit":true},"textDocument":{"completion":{"completionItem":{"snippetSupport":false,"tagSupport":{"valueSet":[1]},"deprecatedSupport":true}},"synchronization":{"willSaveWaitUntil":false,"willSave":false,"didSave":false},"codeAction":{"codeActionLiteralSupport":{"codeActionKind":{"valueSet":["quickfix","refactor","source"]}}},"signatureHelp":{"dynamicRegistration":false},"hover":{"contentFormat":["plaintext","markdown"]},"definition":{"dynamicRegistration":false}}},"clientInfo":{"name":"vim-lsc"},"processId":62896,"trace":"off"}}Content-Length: 52

{"method":"exit","jsonrpc":"2.0"}

And gets these responses:

{"jsonrpc":"2.0","id":2,"result":null}

Do you think the problem is with what Vim is sending to the language server? Should it be including a rootPath parameter somewhere in the initial message? (I tried including one inside the params, with the same value as the rootUri parameter, but then I got an Unhandled exception: No such file or directory error messsage.)

I'd be grateful for any suggestions – thanks!

Thanks for reporting this, the language server now supports the rootUri initialisation parameter 👍

That's brilliant, thank you!
