elixirls

https://github.com/elixir-lsp/elixir-ls

elixir-ls can be installed by following the instructions here.

curl -fLO https://github.com/elixir-lsp/elixir-ls/releases/latest/download/elixir-ls.zip
unzip elixir-ls.zip -d /path/to/elixir-ls
# Unix
chmod +x /path/to/elixir-ls/language_server.sh

By default, elixir-ls doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of your unzipped elixir-ls.

require'lspconfig'.elixirls.setup{
    -- Unix
    cmd = { "/path/to/elixir-ls/language_server.sh" };
    -- Windows
    cmd = { "/path/to/elixir-ls/language_server.bat" };

lspconfig.haxe_language_server.setup({
  cmd = {"node", "path/to/bin/server.js"},

julials

https://github.com/julia-vscode/julia-vscode

LanguageServer.jl can be installed with julia and Pkg:

julia -e 'using Pkg; Pkg.add("LanguageServer"); Pkg.add("SymbolServer")'

The default config lazily evaluates the location of the julia language server from the your global julia packages. This adds a small overhead on first opening of a julia file. To avoid this overhead, replace server_path in on_new_config with a hard-coded path to the server.

require'lspconfig'.julials.setup{
    on_new_config = function(new_config,new_root_dir)
      server_path = "/path/to/directory/containing/LanguageServer.jl/src"
      cmd = {
        "julia",
        "--project="..server_path,
        "--startup-file=no",
        "--history-file=no",
        "-e", [[
          using Pkg;
          Pkg.instantiate()
          using LanguageServer; using SymbolServer;
          depot_path = get(ENV, "JULIA_DEPOT_PATH", "")
          project_path = dirname(something(Base.current_project(pwd()), Base.load_path_expand(LOAD_PATH[2])))
          # Make sure that we only load packages from this environment specifically.
          @info "Running language server" env=Base.load_path()[1] pwd() project_path depot_path
          server = LanguageServer.LanguageServerInstance(stdin, stdout, project_path, depot_path);
          server.runlinter = true;
          run(server);
        \]\]
    };
      new_config.cmd = cmd
    end
}

You can find the path to the globally installed LanguageServer.jl package with the following command:

julia -e 'print(Base.find_package("LanguageServer"))'

Note: the directory passed to --project=... should terminate with src, not LanguageServer.jl.

Omnisharp requires the dotnet-sdk to be installed.

By default, omnisharp-roslyn doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of the unzipped run script or binary.

local pid = vim.fn.getpid()
-- On linux/darwin if using a release build, otherwise under scripts/OmniSharp(.Core)(.cmd)
local omnisharp_bin = "/path/to/omnisharp-repo/run"
-- on Windows
-- local omnisharp_bin = "/path/to/omnisharp/OmniSharp.exe"
require'lspconfig'.omnisharp.setup{
    cmd = { omnisharp_bin, "--languageserver" , "--hostPID", tostring(pid) };
    ...
}

Note, if you download the executable for darwin you will need to strip the quarantine label to run:

find /path/to/omnisharp-osx | xargs xattr -r -d com.apple.quarantine

rescriptls

https://github.com/rescript-lang/rescript-vscode

ReScript language server

By default, rescriptls doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You have to install the language server manually.

You can use the bundled language server inside the vim-rescript repo.

Clone the vim-rescript repo and point cmd to server.js inside server/out directory:

cmd = {'node', '<path_to_repo>/server/out/server.js', '--stdio'}

If you have vim-rescript installed you can also use that installation. for example if you're using packer.nvim you can set cmd to something like this:

cmd = {
  'node',
  '/home/username/.local/share/nvim/site/pack/packer/start/vim-rescript/server/out/server.js',
  '--stdio'
}

Another option is to use vscode extension release. Take a look at here for instructions.

require'lspconfig'.rescriptls.setup{}

Commands and default values:

  Commands:
  
  Default Values:
    cmd = {}

sumneko_lua

https://github.com/sumneko/lua-language-server

Lua language server.

lua-language-server can be installed by following the instructions here.

By default, lua-language-server doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of your unzipped and compiled lua-language-server.

local system_name
if vim.fn.has("mac") == 1 then
  system_name = "macOS"
elseif vim.fn.has("unix") == 1 then
  system_name = "Linux"
elseif vim.fn.has('win32') == 1 then
  system_name = "Windows"
else
  print("Unsupported system for sumneko")
end

-- set the path to the sumneko installation; if you previously installed via the now deprecated :LspInstall, use
local sumneko_root_path = vim.fn.stdpath('cache')..'/lspconfig/sumneko_lua/lua-language-server'
local sumneko_binary = sumneko_root_path.."/bin/"..system_name.."/lua-language-server"

local runtime_path = vim.split(package.path, ';')
table.insert(runtime_path, "lua/?.lua")
table.insert(runtime_path, "lua/?/init.lua")

require'lspconfig'.sumneko_lua.setup {
  cmd = {sumneko_binary, "-E", sumneko_root_path .. "/main.lua"};
  settings = {
    Lua = {
      runtime = {
        -- Tell the language server which version of Lua you're using (most likely LuaJIT in the case of Neovim)
        version = 'LuaJIT',
        -- Setup your lua path
        path = runtime_path,
      },
      diagnostics = {
        -- Get the language server to recognize the `vim` global

tailwindcss

https://github.com/tailwindlabs/tailwindcss-intellisense

Tailwind CSS Language Server

NOTE: The current tailwindcss-language-server npm package is a different project.

Until the standalone server is published to npm, you can extract the server from the VS Code package:

curl -L -o tailwindcss-intellisense.vsix https://github.com/tailwindlabs/tailwindcss-intellisense/releases/download/v0.6.8/vscode-tailwindcss-0.6.8.vsix
unzip tailwindcss-intellisense.vsix -d tailwindcss-intellisense
echo "#\!/usr/bin/env node\n$(cat tailwindcss-intellisense/extension/dist/server/tailwindServer.js)" > tailwindcss-language-server
chmod +x tailwindcss-language-server

Copy or symlink tailwindcss-language-server to somewhere in your $PATH.

zeta_note

https://github.com/artempyanykh/zeta-note

Markdown LSP server for easy note-taking with cross-references and diagnostics.

Binaries can be downloaded from https://github.com/artempyanykh/zeta-note/releases

By default, zeta-note doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of your zeta-note binary.

require'lspconfig'.zeta_note.setup{
  cmd = {'path/to/zeta-note'}
}

This server accepts configuration via the settings key.

Available settings:

  • zetaNote.customCommand: string

    When set use this command to run the language server. The command is split on spaces: first part is the command name, the rest is the arguments.

  • zetaNote.customCommandDir: string

    null

  • zetaNote.trace.server: enum { "off", "messages", "verbose" }

    Default: "verbose"
