arduino_language_server

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

Language server for Arduino

The arduino-language-server can be installed by running:

go install github.com/arduino/arduino-language-server@latest

The arduino-cli tool must also be installed. Follow these installation instructions for your platform.

After installing arduino-cli, follow these instructions for generating a configuration file if you haven't done so already, and make sure you install any relevant platforms libraries. Make sure to save the full path to the created arduino-cli.yaml file for later.

The language server also requires clangd to be installed. Follow these installation instructions for your platform.

Next, you will need to decide which FQBN to use. To identify the available FQBNs for boards you currently have connected, you may use the arduino-cli command, like so:

$ arduino-cli board list
Port         Protocol Type              Board Name  FQBN            Core
/dev/ttyACM0 serial   Serial Port (USB) Arduino Uno arduino:avr:uno arduino:avr
                                                    ^^^^^^^^^^^^^^^

After all dependencies are installed you'll need to set the command for the language server in your setup:

require'lspconfig'.arduino_language_server.setup {
  cmd = {
    "arduino-language-server",
    "-cli-config", "/path/to/arduino-cli.yaml",
    "-fqbn", "arduino:avr:uno",
    "-cli", "arduino-cli",
    "-clangd", "clangd"
  }
}

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

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 \

efm

https://github.com/mattn/efm-langserver

General purpose Language Server that can use specified error message format generated from specified command.

Requires at minimum EFM version v0.0.38 to support launching the language server on single files. If on an older version of EFM, disable single file support:

require('lspconfig')['efm'].setup{
  settings = ..., -- You must populate this according to the EFM readme
  filetypes = ..., -- Populate this according to the note below
  single_file_support = false, -- This is the important line for supporting older version of EFM
}

Note: In order for neovim's built-in language server client to send the appropriate languageId to EFM, you must specify filetypes in your call to setup{}. Otherwise lspconfig will launch EFM on the BufEnter instead of the FileType autocommand, and the filetype variable used to populate the languageId will not yet be set.

require('lspconfig')['efm'].setup{
  settings = ..., -- You must populate this according to the EFM readme
  filetypes = { 'python','cpp','lua' }
}

Snippet to enable the language server:

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"
    }
}

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.

Snippet to enable the language server:

require'lspconfig'.idris2_lsp.setup{}

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 and ensure that the PATH variable contains the bin directory of the extracted archive.

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

You can also pass extra custom jvm arguments with the JDTLS_JVM_ARGS environment variable as a space separated list of arguments, that will be converted to multiple --jvm-arg= args when passed to the jdtls script. This will allow for example tweaking the jvm arguments or integration with external tools like lombok:

export JDTLS_JVM_ARGS="-javaagent:$HOME/.local/share/java/lombok.jar"

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' } }

perlnavigator

https://github.com/bscan/PerlNavigator

A Perl language server

By default, perlnavigator 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.

Clone the PerlNavigator repo, install based on the instructions, and point cmd to server.js inside the server/out directory:

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

At minimum, you will need perl in your path. If you want to use a non-standard perl you will need to set your configuration like so:

settings = {
  perlnavigator = {
    perlPath = '/some/odd/location/my-perl'
  }
}

The contributes.configuration.properties section of perlnavigator's package.json has all available configuration settings. All settings have a reasonable default, but, at minimum, you may want to point perlnavigator at your perltidy and perlcritic configurations.

https://github.com/PowerShell/PowerShellEditorServices

Language server for PowerShell.

To install, download and extract PowerShellEditorServices.zip from the releases. To configure the language server, set the property bundle_path to the root of the extracted PowerShellEditorServices.zip.

The default configuration doesn't set cmd unless bundle_path is specified.

require'lspconfig'.powershell_es.setup{
  bundle_path = 'c:/w/PowerShellEditorServices',
}

By default the languageserver is started in pwsh (PowerShell Core). This can be changed by specifying shell.

require'lspconfig'.powershell_es.setup{
  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.

require'lspconfig'.powershell_es.setup{
  cmd = {'pwsh', '-NoLogo', '-NoProfile', '-Command', "c:/PSES/Start-EditorServices.ps1 ..."}
}

Setup:

- Make sure you have a Relay config file somewhere in your project.
- We support standard config file formats (`.yml`, `.js`, `.json`), and the the `relay` field in your `package.json`
- Make sure you have the `relay-compiler` installed in your project. The bare minimum is v13.
- Make sure you are able to run the `relay-compiler` command from the command line. If `yarn relay-compiler` works, it's very likely that the LSP will work.
- Remove / disable any conflicting GraphQL LSPs you have installed.

Relay LSP is a part of the Relay Compiler binary and available when adding `relay-compiler` to your project's devDependencies.

```lua
require'lspconfig'.relay_lsp.setup {
  -- (default: false) Whether or not we should automatically start
  -- the Relay Compiler in watch mode when you open a project
  auto_start_compiler = false,


  -- (default: null) Path to a relay config relative to the
  -- `root_dir`. Without this, the compiler will search for your
  -- config. This is helpful if your relay project is in a nested
  -- directory.
  path_to_config = nil,
}
```

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.

Snippet to enable the language server:

require'lspconfig'.rescriptls.setup{}

Default values:

  • cmd :
{}
  • filetypes :
{ "rescript" }

If you use brownie, use this root_dir: root_dir = util.root_pattern('brownie-config.yaml', '.git')

on includePath, you can add an extra path to search for external libs, on remapping you can remap lib <> path, like:

{ solidity = { includePath = '/Users/your_user/.brownie/packages/', remapping = { ["@OpenZeppelin/"] = 'OpenZeppelin/[email protected]/' } } }

For brownie users Change the root_dir to:

root_pattern("brownie-config.yaml", ".git")

The best way of using it is to have a package.json in your project folder with the packages that you will use. After installing with package.json, just create a remappings.txt with:

The default cmd assumes that the lua-language-server binary can be found in $PATH.

If you primarily use lua-language-server for Neovim, and want to provide completions, analysis, and location handling for plugins on runtime path, you can use the following settings.

Note: that these settings will meaningfully increase the time until lua-language-server can service initial requests (completion, location) upon starting as well as time to first diagnostics. Completion results will include a workspace indexing progress message until the server has finished indexing.

require'lspconfig'.sumneko_lua.setup {
  settings = {
    Lua = {
      runtime = {
        -- Tell the language server which version of Lua you're using (most likely LuaJIT in the case of Neovim)
        version = 'LuaJIT',
      },
      diagnostics = {
        -- Get the language server to recognize the `vim` global
        globals = {'vim'},
      },
      workspace = {
        -- Make the server aware of Neovim runtime files
        library = vim.api.nvim_get_runtime_file("", true),
      },
      -- Do not send telemetry data containing a randomized but unique identifier
      telemetry = {
        enable = false,
      },
    },
  },
}

See lua-language-server's documentation for an explanation of the above fields:

volar

https://github.com/johnsoncodehk/volar/tree/20d713b/packages/vue-language-server

Volar language server for Vue

Volar can be installed via npm:

npm install -g @volar/vue-language-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. This can lead to issues e.g. when working on a monorepo. The alternatives are:

  • use a global TypeScript Server installation
require'lspconfig'.volar.setup{
  init_options = {
    typescript = {
      tsdk = '/path/to/.npm/lib/node_modules/typescript/lib'
      -- Alternative location if installed as root:
      -- tsdk = '/usr/local/lib/node_modules/typescript/lib'
    }
  }
}
  • use a local server and fall back to a global TypeScript Server installation
local util = require 'lspconfig.util'
local function get_typescript_server_path(root_dir)

  local global_ts = '/home/[yourusernamehere]/.npm/lib/node_modules/typescript/lib'
  -- Alternative location if installed as root:
  -- local global_ts = '/usr/local/lib/node_modules/typescript/lib'
  local found_ts = ''
  local function check_dir(path)
    found_ts =  util.path.join(path, 'node_modules', 'typescript', 'lib')
    if util.path.exists(found_ts) then
      return path
    end
  end
  if util.search_ancestors(root_dir, check_dir) then
    return found_ts
  else
    return global_ts
  end
end

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

      schemas = {
        ["https://raw.githubusercontent.com/instrumenta/kubernetes-json-schema/master/v1.18.0-standalone-strict/all.json"] = "/*.k8s.yaml",
        ... -- other schemas
      },
    },
  }
}
