arduino_language_server

https://github.com/arduino/arduino-language-server

Language server for Arduino

The arduino-language-server can be installed by running: go get -u github.com/arduino/arduino-language-server

The arduino-cli tools must also be installed. Follow these instructions for your distro: https://arduino.github.io/arduino-cli/latest/installation/

After installing the arduino-cli tools, follow these instructions for generating a configuration file: https://arduino.github.io/arduino-cli/latest/getting-started/#create-a-configuration-file and make sure you install any relevant platforms libraries: https://arduino.github.io/arduino-cli/latest/getting-started/#install-the-core-for-your-board

The language server also requires clangd be installed. It will look for clangd by default but the binary path can be overridden if need be.

After all dependencies are installed you'll need to override the lspconfig command for the language server in your setup function with the necessary configurations:

lspconfig.arduino_language_server.setup({
	cmd =  {
		-- Required
		"arduino-language-server",
		"-cli-config", "/path/to/arduino-cli.yaml",
		-- Optional
		"-cli", "/path/to/arduino-cli",
		"-clangd", "/path/to/clangd"
	}
})

For further instruction about configuration options, run arduino-language-server --help.

Snippet to enable the language server:

require'lspconfig'.arduino_language_server.setup{}

Commands and default values:

  Commands:
  
  Default Values:
    cmd = { "arduino-language-server" }

bicep

https://github.com/azure/bicep Bicep language server

Bicep language server can be installed by downloading and extracting a release of bicep-langserver.zip from Bicep GitHub releases.

Bicep language server requires the dotnet-sdk to be installed.

Neovim does not have built-in support for the bicep filetype which is required for lspconfig to automatically launch the language server.

Filetype detection can be added via an autocmd:

vim.cmd [[ autocmd BufNewFile,BufRead *.bicep set filetype=bicep ]]

By default, bicep language server does not 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 bicep_lsp_bin = "/path/to/bicep-langserver/Bicep.LangServer.dll"
require'lspconfig'.bicep.setup{
    cmd = { "dotnet", bicep_lsp_bin };
    ...
}

To download the latest release and place in /usr/local/bin/bicep-langserver:

(cd $(mktemp -d) \
    && curl -fLO https://github.com/Azure/bicep/releases/latest/download/bicep-langserver.zip \
    && rm -rf /usr/local/bin/bicep-langserver \
    && unzip -d /usr/local/bin/bicep-langserver bicep-langserver.zip)

esbonio

https://github.com/swyddfa/esbonio

Esbonio is a language server for Sphinx documentation projects. The language server can be installed via pip

pip install esbonio

Since Sphinx is highly extensible you will get best results if you install the language server in the same Python environment as the one used to build your documentation. To ensure that the correct Python environment is picked up, you can either launch nvim with the correct environment activated.

source env/bin/activate
nvim

Or you can modify the default cmd to include the full path to the Python interpreter.

require'lspconfig'.esbonio.setup {
  cmd = { '/path/to/virtualenv/bin/python', '-m', 'esbonio' }
}

Esbonio supports a number of config values passed as init_options on startup, for example.

require'lspconfig'.esbonio.setup {
  init_options = {
    server = {
      logLevel = "debug"
    },
    sphinx = {
      confDir = "/path/to/docs",
      srcDir = "${confDir}/../docs-src"
    }
}

A full list and explanation of the available options can be found here

idris2_lsp

https://github.com/idris-community/idris2-lsp

The Idris 2 language server.

Plugins for the Idris 2 filetype include Idris2-Vim (fewer features, stable) and Nvim-Idris2 (cutting-edge, experimental).

Idris2-Lsp requires a build of Idris 2 that includes the "Idris 2 API" package. Package managers with known support for this build include the AUR and Homebrew.

If your package manager does not support the Idris 2 API, you will need to build Idris 2 from source. Refer to the the Idris 2 installation instructions for details. Steps 5 and 8 are listed as "optional" in that guide, but they are necessary in order to make the Idris 2 API available.

You need to install a version of Idris2-Lsp that is compatible with your version of Idris 2. There should be a branch corresponding to every released Idris 2 version after v0.4.0. Use the latest commit on that branch. For example, if you have Idris v0.5.1, you should use the v0.5.1 branch of Idris2-Lsp.

If your Idris 2 version is newer than the newest Idris2-Lsp branch, use the latest commit on the master branch, and set a reminder to check the Idris2-Lsp repo for the release of a compatible versioned branch.

jdtls

https://projects.eclipse.org/projects/eclipse.jdt.ls

Language server for Java.

IMPORTANT: If you want all the features jdtls has to offer, nvim-jdtls is highly recommended. If all you need is diagnostics, completion, imports, gotos and formatting and some code actions you can keep reading here.

For manual installation you can download precompiled binaries from the official downloads site

Due to the nature of java, settings cannot be inferred. Please set the following environmental variables to match your installation. If you need per-project configuration direnv is highly recommended.

# Mandatory:
# .bashrc
export JDTLS_HOME=/path/to/jdtls_root # Directory with the plugin and configs directories

# Optional:
export JAVA_HOME=/path/to/java_home # In case you don't have java in path or want to use a version in particular
export WORKSPACE=/path/to/workspace # Defaults to $HOME/workspace

  -- init.lua
  require'lspconfig'.jdtls.setup{}

For automatic installation you can use the following unofficial installers/launchers under your own risk:

• jdtls-launcher (Includes lombok support by default)

    -- init.lua
    require'lspconfig'.jdtls.setup{ cmd = { 'jdtls' } }

kotlin_language_server

A kotlin language server which was developed for internal usage and
released afterwards. Maintaining is not done by the original author,
but by fwcd.

It is built via gradle and developed on github.
Source and additional description:
https://github.com/fwcd/kotlin-language-server

This server requires vim to be aware of the kotlin-filetype.
You could refer for this capability to:
https://github.com/udalov/kotlin-vim (recommended)
Note that there is no LICENSE specified yet.

This server accepts configuration via the settings key.

Available settings:

• kotlin.compiler.jvm.target: string

  Default: "default"

  Specifies the JVM target, e.g. "1.6" or "1.8"

• kotlin.completion.snippets.enabled: boolean

  Default: true

  Specifies whether code completion should provide snippets (true) or plain-text items (false).

• kotlin.debounceTime: integer

  Default: 250

  [DEPRECATED] Specifies the debounce time limit. Lower to increase responsiveness at the cost of possible stability issues.

• kotlin.debugAdapter.enabled: boolean

  Default: true

  [Recommended] Specifies whether the debug adapter should be used. When enabled a debugger for Kotlin will be available.

• kotlin.debugAdapter.path: string

  Default: ""

  Optionally a custom path to the debug adapter executable.

• kotlin.externalSources.autoConvertToKotlin: boolean

  Default: true

  Specifies whether decompiled/external classes should be auto-converted to Kotlin.

• kotlin.externalSources.useKlsScheme: boolean

  Default: true

  [Recommended] Specifies whether URIs inside JARs should be represented using the 'kls'-scheme.

• kotlin.indexing.enabled: boolean

  Default: true

  Whether global symbols in the project should be indexed automatically in the background. This enables e.g. code completion for unimported classes and functions.

• kotlin.languageServer.debugAttach.autoSuspend: boolean

  [DEBUG] If enabled (together with debugAttach.enabled), the language server will not immediately launch but instead listen on the specified attach port and wait for a debugger. This is ONLY useful if you need to debug the language server ITSELF.

• kotlin.languageServer.debugAttach.enabled: boolean

  [DEBUG] Whether the language server should listen for debuggers, i.e. be debuggable while running in VSCode. This is ONLY useful if you need to debug the language server ITSELF.

• kotlin.languageServer.debugAttach.port: integer

  Default: 5005

  [DEBUG] If transport is stdio this enables you to attach to the running language server with a debugger. This is ONLY useful if you need to debug the language server ITSELF.

• kotlin.languageServer.enabled: boolean

  Default: true

  [Recommended] Specifies whether the language server should be used. When enabled the extension will provide code completions and linting, otherwise just syntax highlighting. Might require a reload to apply.

• kotlin.languageServer.path: string

  Default: ""

  Optionally a custom path to the language server executable.

• kotlin.languageServer.port: integer

  Default: 0

  The port to which the client will attempt to connect to. A random port is used if zero. Only used if the transport layer is TCP.

• kotlin.languageServer.transport: enum { "stdio", "tcp" }

  Default: "stdio"

  The transport layer beneath the language server protocol. Note that the extension will launch the server even if a TCP socket is used.

• kotlin.linting.debounceTime: integer

  Default: 250

  [DEBUG] Specifies the debounce time limit. Lower to increase responsiveness at the cost of possible stability issues.

• kotlin.snippetsEnabled: boolean

  Default: true

  [DEPRECATED] Specifies whether code completion should provide snippets (true) or plain-text items (false).

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

    single_file_support = true

leanls

https://github.com/leanprover/lean4

Lean installation instructions can be found here.

The Lean 4 language server is built-in with a Lean 4 install (and can be manually run with, e.g., lean --server).

Note: that if you're using lean.nvim, that plugin fully handles the setup of the Lean language server, and you shouldn't set up leanls both with it and lspconfig.

          return path
        end
      end)
    end

lemminx

https://github.com/eclipse/lemminx

The easiest way to install the server is to get a binary at https://download.jboss.org/jbosstools/vscode/stable/lemminx-binary/ and place it in your PATH.

By default, lemminx 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 lemminx.

require'lspconfig'.lemminx.setup{
    cmd = { "/path/to/lemminx/lemminx" };
    ...
}

NOTE to macOS users: Binaries from unidentified developers are blocked by default. If you trust the downloaded binary from jboss.org, run it once, cancel the prompt, then remove the binary from Gatekeeper quarantine with xattr -d com.apple.quarantine lemminx. It should now run without being blocked.

Snippet to enable the language server:

require'lspconfig'.lemminx.setup{}

Commands and default values:

  Commands:
  
  Default Values:
    filetypes = { "xml", "xsd", "svg" }

  bundle_path = 'c:/w/PowerShellEditorServices',
  shell = 'powershell.exe',
}

Note that the execution policy needs to be set to Unrestricted for the languageserver run under PowerShell

If necessary, specific cmd can be defined instead of bundle_path. See PowerShellEditorServices to learn more.

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 = {

Both HashiCorp and the maintainer of terraform-lsp expressed interest in collaborating on a language server and are working towards a long-term goal of a single stable and feature-complete implementation.

For the time being both projects continue to exist, giving users the choice:

• terraform-ls providing

  • overall stability (by relying only on public APIs)
  • compatibility with any provider and any Terraform >=0.12.0 currently less features
  • due to project being younger and relying on public APIs which may not offer the same functionality yet

• terraform-lsp providing

  • currently more features
  • compatibility with a single particular Terraform (0.12.20 at time of writing)
    • configs designed for other 0.12 versions may work, but interpretation may be inaccurate
  • less stability (due to reliance on Terraform's own internal packages)

https://github.com/nickbattle/vdmj

The VDMJ language server can be installed by cloning the VDMJ repository and running mvn clean install.

Various options are provided to configure the language server (see below). In particular:

• annotation_paths is a list of folders and/or jar file paths for annotations that should be used with the language server;
• any value of debugger_port less than zero will disable the debugger; note that if a non-zero value is used, only one instance of the server can be active at a time.

More settings for VDMJ can be changed in a file called vdmj.properties under root_dir/.vscode. For a description of the available settings, see Section 7 of the VDMJ User Guide.

Note: proof obligations and combinatorial testing are not currently supported by neovim.

vls

https://github.com/vlang/vls

V language server.

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

By default, v-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 v-language-server.

-- set the path to the vls installation;
local vls_root_path = vim.fn.stdpath('cache')..'/lspconfig/vls'
local vls_binary = vls_root_path.."/cmd/vls/vls"

require'lspconfig'.vls.setup {

volar

https://github.com/johnsoncodehk/volar/tree/master/packages/server

Volar language server for Vue

Volar can be installed via npm:

npm install -g @volar/server

Volar by default supports Vue 3 projects. Vue 2 projects need additional configuration.

Take Over Mode Volar can serve as a language server for both Vue and TypeScript via Take Over Mode.

To enable Take Over Mode, override the default filetypes in setup{} as follows:

require'lspconfig'.volar.setup{
  filetypes = {'typescript', 'javascript', 'javascriptreact', 'typescriptreact', 'vue', 'json'}
}

Overriding the default TypeScript Server used by Volar The default config looks for TS in the local node_modules. The alternatives are:

• use a global TypeScript Server installation

require'lspconfig'.volar.setup{
  init_options = {
    typescript = {
      serverPath = '/path/to/.npm/lib/node_modules/typescript/lib/tsserverlib.js'
    }
  }
}

• use a global TypeScript Server installation if a local server is not found

local util = require 'lspconfig.util'

local function get_typescript_server_path(root_dir)
  local project_root = util.find_node_modules_ancestor(root_dir)

  local local_tsserverlib = project_root ~= nil and util.path.join(project_root, 'node_modules', 'typescript', 'lib', 'tsserverlibrary.js')
  local global_tsserverlib = '/home/[yourusernamehere]/.npm/lib/node_modules/typescript/lib/tsserverlibrary.js'

  if local_tsserverlib and util.path.exists(local_tsserverlib) then
    return local_tsserverlib
  else
    return global_tsserverlib
  end
end

require'lspconfig'.volar.setup{
  config = {
    on_new_config = function(new_config, new_root_dir)
      new_config.init_options.typescript.serverPath = get_typescript_server_path(new_root_dir)

yamlls

https://github.com/redhat-developer/yaml-language-server

yaml-language-server can be installed via yarn:

yarn global add yaml-language-server

To use a schema for validation, there are two options:

1. Add a modeline to the file. A modeline is a comment of the form:

# yaml-language-server: $schema=<urlToTheSchema|relativeFilePath|absoluteFilePath}>

where the relative filepath is the path relative to the open yaml file, and the absolute filepath is the filepath relative to the filesystem root ('/' on unix systems)

2. Associated a schema url, relative , or absolute (to root of project, not to filesystem root) path to the a glob pattern relative to the detected project root. Check :LspInfo to determine the resolved project root.

require('lspconfig').yamlls.setup {
  ... -- other configuration for setup {}
  settings = {
    yaml = {
      ... -- other settings. note this overrides the lspconfig defaults.
      schemas = {
        ["https://json.schemastore.org/github-workflow.json"] = "/.github/workflows/*"
        ["../path/relative/to/file.yml"] = "/.github/workflows/*"
        ["/path/from/root/of/project"] = "/.github/workflows/*"
      },
    },
  }
}

Currently, kubernetes is special-cased in yammls, see the following upstream issues:

• #211.
• #307.

To override a schema to use a specific k8s schema version (for example, to use 1.18):

require('lspconfig').yamlls.setup {
  ... -- other configuration for setup {}
  settings = {
    yaml = {
      ... -- other settings. note this overrides the lspconfig defaults.
      schemas = {
        ["https://raw.githubusercontent.com/instrumenta/kubernetes-json-schema/master/v1.18.0-standalone-strict/all.json"] = "/*.k8s.yaml",
        ... -- other schemas
      },
    },
  }
}

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"

  Level of verbosity in communicating with the server
