Can't configure for vscode-html-languageserver (it doesn't work with default or basic configuration)

[JustAnotherCodemonkey]

When I installed the VS Code language server via Nix (nodePackages.vscode-html-languageserver-bin package using nix profile install), Helix did not detect it and could not find the bin. This is likely because it was looking for "vscode-html-languageserver" or something like that but the actual bin installed was "html-languageserver".

I modified languages.toml, adding

[[language]]
name = "html"
language-servers = [ "html-languageserver" ]

However, I get the message "helix_view::editor [ERROR] Failed to initialize the language servers for text.html.basic - html-languageserver { Language server 'html-languageserver' not defined }" in the log and get no lsp when editing HTML.

You should use the nodePackages.vscode-langservers-extracted package from nixpkgs instead, vscode-html-languageserver-bin is something else.

The language-servers key under [[language]] controls which language-server entry you use. For example the default ones:

helix/languages.toml

Lines 6 to 19 in 786b5c5

	[language-server]
	als = { command = "als" }
	awk-language-server = { command = "awk-language-server" }
	bash-language-server = { command = "bash-language-server", args = ["start"] }
	bass = { command = "bass", args = ["--lsp"] }
	bicep-langserver = { command = "bicep-langserver" }
	bufls = { command = "bufls", args = ["serve"] }
	cairo-language-server = { command = "cairo-language-server", args = [] }
	cl-lsp = { command = "cl-lsp", args = [ "stdio" ] }
	clangd = { command = "clangd" }
	clojure-lsp = { command = "clojure-lsp" }
	cmake-language-server = { command = "cmake-language-server" }
	crystalline = { command = "crystalline", args = ["--stdio"] }

If you want to change the command name for an existing language server you can modify that instead:

# ~/.config/helix/languages.toml
[language-server.vscode-html-language-server]
command = "my-language-server-command"
args = []
config = {}

Thank you but frankly I have no idea what you're talking about in the first part. "nodePackages.vscode-langservers-extracted" is not a package in the nix package repository. The second part makes sense though and I'll try that. Thank you
