Tailwind language server shows errors

[volucris1]

Helix showing me this:

Async job failed: protocol error: Method not found: Unhandled method textDocument/completion

And there is my languages.toml

[[language]]
name = "tailwind"
scope = "source.svelte"
roots = [".npmrc"]
file-types = ["svelte"]
language-server = { command = "/home/yura/.local/share/nvim/lsp_servers/tailwindcss_npm/node_modules/@tailwindcss/language-server/bin/tailwindcss-language-server", args = ["--stdio"] }

[the-mikedavis]

It looks like the tailwind LS has a troubleshooting section here: https://github.com/tailwindlabs/tailwindcss-intellisense#troubleshooting and some available configuration above. You can also run in verbose mode with the -v flags (up to three of them) and check what messages are passed between the LS and helix https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file

[hucancode]

I got the same error

My language.toml

[[language]]
name = "tailwindcss"
scope = "source.css"
injection-regex = "(postcss|css)"
file-types = ["css"]
roots = ["tailwind.config.js","tailwind.config.cjs"]
comment-token = "//"
language-server = { command = "tailwindcss-language-server", args = ["--stdio"] }
indent = { tab-width = 2, unit = "  " }

[gasacchi]

any info for this? not working and even broke svelte syntax highlighting and completions

my languages.toml file:

[[language]]
name = "tailwind"
scope = "source.svelte"
file-types = ["svelte"]
roots = ["tailwind.config.js","tailwind.config.cjs"]
language-server = { command = "tailwindcss-language-server", args = ["--stdio"] }

[aguilera51284]

any update?

[anbcodes]

I looked into this some, it appears that the tailwindcss language server expects the config to be an object, and so crashes when a config is not provided, which means the language server never registers the textDocument/completion handler.

Here are the specific lines

      userLanguages: params.initializationOptions.userLanguages
        ? params.initializationOptions.userLanguages
        : {},

Tailwindcss never checks to make sure initializationOptions is in fact an object.

My configuration file that does not produce that error looks like this

[[language]]
name = "tailwindcss"
scope = "source.css"
injection-regex = "(postcss|css|html)"
file-types = ["css"]
roots = ["tailwind.config.js","tailwind.config.cjs"]
language-server = { command = "tailwindcss-language-server", args = ["-vvv", "--stdio"] }
indent = { tab-width = 2, unit = "  " }
config = { } # <---- this is the partial fix

But even though the error went away (and the logs show the language server working), it's still not giving completions. (The server keeps returning null for the list of completions)

2022-11-08T16:06:58.671 helix_lsp::transport [INFO] -> {"jsonrpc":"2.0","method":"textDocument/completion","params":{"position":{"character":16,"line":1},"textDocument":{"uri":"file:///home/andrew/Code/js/spry/landing-svelte/src/routes/+page.svelte"}},"id":4}
2022-11-08T16:06:58.674 helix_lsp::transport [INFO] <- {"jsonrpc":"2.0","id":4,"result":null}

I haven't figured the issue out, but I thought I would write down what I've discovered so far.

Update: In a .postcss file after setting the language to tailwindcss, autocomplete works, it is just in svelte that it isn't working

Update 2:

I solved it! Tailwindcss determines which type of file you are in based on the language-id parameter, so a working configuration for svelte files (only) is below.

[[language]]
name = "tailwind-svelte"
scope = "source.svelte"
file-types = ["svelte"]
roots = ["tailwind.config.js","tailwind.config.cjs"]
language-server = { language-id = "svelte", command = "tailwindcss-language-server", args = ["--stdio"] }
config = { }

You need to modify each language tailwindcss works with and overwrite it with tailwindcss and the correct language-id. Unfortunately, this overwrites the existing language server for all those languages. Until #2507 is merged, there isn't a way to add two language servers to the same language. Once that PR is merged a configuration file for tailwindcss (for Svelte, CSS, and HTML) would look like this (which is the config I am currently using after building the PR myself).

[[language]]
name = "svelte"
scope = "source.svelte"
file-types = ["svelte"]
roots = ["tailwind.config.js","tailwind.config.cjs"]
language-servers = [ "tailwindcss-svelte", "svelteserver" ]

[language-server.tailwindcss-svelte]
language-id = "svelte"
command = "tailwindcss-language-server"
args = ["--stdio"]
config = { }

[[language]]
name = "css"
scope = "source.css"
file-types = ["css", "postcss"]
language-servers = [ "tailwindcss-css", "vscode-css-language-server" ]

[language-server.tailwindcss-css]
language-id = "css"
command = "tailwindcss-language-server"
args = ["--stdio"]
config = { }

[[language]]
name = "html"
scope = "text.html.basic"
file-types = ["html"]
language-servers = [ "tailwindcss-html", "vscode-html-language-server" ]

[language-server.tailwindcss-html]
language-id = "html"
command = "tailwindcss-language-server"
args = ["--stdio"]
config = { }

[anbcodes]

Once tailwindlabs/tailwindcss-intellisense#656 is released the config will be able to be empty without causing tailwind to crash, which fixes this bug.

[H4ckint0sh]

Any news on this. Should it work now? I am not able to use this.

[uros-5]

Current problem is that with #2507, hover doesn't work if tailwindcss is not first language added to language-servers..

When Svelte or Vue are second in that array then their features are not working.

I tried to change that, and it works 😃

My temp fork.

[arnm]

Anyone do this with tsx files ?

[aliade-consid]

@arnm Did you found any solutions?

[gigantino]

Now that it has been merged did someone experiment already with TSX and Tailwind?
This was my current attempt but I'm most likely doing something wrong:

[[language]]
name = "typescript"
roots = ["tailwind.config.js", "tailwind.config.cjs"]
language-servers = [ "tailwindcss-typescript", "typescript-language-server" ]

[language-server.tailwindcss-typescript]
language-id = "typescript"
command = "tailwindcss-language-server"
args = ["--stdio"]
config = { }

[happysalada]

I'm trying with

language-servers = ["svelteserver", "tailwindcss"]
name = "svelte"
roots = ["tailwind.config.cjs", "tailwind.config.js"]
