Can be configured by passing a "settings" object to `als.setup{}`: ```lua require('lspconfig').als.setup{ settings = { ada = { projectFile = "project.gpr"; scenarioVariables = { ... }; } } } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.als.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "ada_language_server" } filetypes = { "ada" } root_dir = util.root_pattern("Makefile", ".git", "*.gpr", "*.adc") ``` ## angularls https://github.com/angular/vscode-ng-language-service `angular-language-server` can be installed via npm `npm install -g @angular/language-server`. Note, that if you override the default `cmd`, you must also update `on_new_config` to set `new_config.cmd` during startup. ```lua local project_library_path = "/path/to/project/lib" local cmd = {"ngserver", "--stdio", "--tsProbeLocations", project_library_path , "--ngProbeLocations", project_library_path} require'lspconfig'.angularls.setup{ cmd = cmd, on_new_config = function(new_config,new_root_dir) new_config.cmd = cmd end, } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.angularls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "ngserver", "--stdio", "--tsProbeLocations", "", "--ngProbeLocations", "" } filetypes = { "typescript", "html", "typescriptreact", "typescript.tsx" } root_dir = root_pattern("angular.json", ".git") ``` ## ansiblels https://github.com/ansible/ansible-language-server Language server for the ansible configuration management tool. `ansible-language-server` can be installed via `npm`: ```sh npm install -g @ansible/ansible-language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.ansiblels.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "ansible-language-server", "--stdio" } filetypes = { "yaml.ansible" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end settings = { ansible = { ansible = { path = "ansible" }, ansibleLint = { enabled = true, path = "ansible-lint" }, executionEnvironment = { enabled = false }, python = { interpreterPath = "python" } } } single_file_support = true ``` ## 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: ```lua 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:** ```lua require'lspconfig'.arduino_language_server.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "arduino-language-server" } filetypes = { "arduino" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end ``` ## asm_lsp https://github.com/bergercookie/asm-lsp Language Server for GAS/GO Assembly `asm-lsp` can be installed via cargo: cargo install asm-lsp **Snippet to enable the language server:** ```lua require'lspconfig'.asm_lsp.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "asm-lsp" } filetypes = { "asm", "vmasm" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end ``` ## awk_ls https://github.com/Beaglefoot/awk-language-server/ `awk-language-server` can be installed via `npm`: ```sh npm install -g awk-language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.awk_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "awk-language-server" } filetypes = { "awk" } single_file_support = true ``` ## bashls https://github.com/mads-hartmann/bash-language-server `bash-language-server` can be installed via `npm`: ```sh npm i -g bash-language-server ``` Language server for bash, written using tree sitter in typescript. **Snippet to enable the language server:** ```lua require'lspconfig'.bashls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "bash-language-server", "start" } cmd_env = { GLOB_PATTERN = "*@(.sh|.inc|.bash|.command)" } filetypes = { "sh" } root_dir = util.find_git_ancestor single_file_support = true ``` ## beancount https://github.com/polarmutex/beancount-language-server#installation See https://github.com/polarmutex/beancount-language-server#configuration for configuration options **Snippet to enable the language server:** ```lua require'lspconfig'.beancount.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "beancount-langserver", "--stdio" } filetypes = { "beancount" } init_options = { journalFile = "", pythonPath = "python3" } root_dir = root_pattern("elm.json") single_file_support = true ``` ## 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](https://github.com/Azure/bicep/releases). Bicep language server requires the [dotnet-sdk](https://dotnet.microsoft.com/download) 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: ```lua 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. ```lua 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: ```bash (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) ``` **Snippet to enable the language server:** ```lua require'lspconfig'.bicep.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "bicep" } init_options = {} root_dir = util.find_git_ancestor ``` ## bsl_ls https://github.com/1c-syntax/bsl-language-server Language Server Protocol implementation for 1C (BSL) - 1C:Enterprise 8 and OneScript languages. **Snippet to enable the language server:** ```lua require'lspconfig'.bsl_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "bsl", "os" } root_dir = root_pattern(".git") ``` ## ccls https://github.com/MaskRay/ccls/wiki ccls relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified as compile_commands.json or, for simpler projects, a .ccls. For details on how to automatically generate one using CMake look [here](https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html). Alternatively, you can use [Bear](https://github.com/rizsotto/Bear). Customization options are passed to ccls at initialization time via init_options, a list of available options can be found [here](https://github.com/MaskRay/ccls/wiki/Customization#initialization-options). For example: ```lua local lspconfig = require'lspconfig' lspconfig.ccls.setup { init_options = { compilationDatabaseDirectory = "build"; index = { threads = 0; }; clang = { excludeArgs = { "-frounding-math"} ; }; } } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.ccls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "ccls" } filetypes = { "c", "cpp", "objc", "objcpp" } offset_encoding = "utf-32" root_dir = root_pattern("compile_commands.json", ".ccls", ".git") single_file_support = false ``` ## clangd https://clangd.llvm.org/installation.html **NOTE:** Clang >= 9 is recommended! See [this issue for more](https://github.com/neovim/nvim-lsp/issues/23). clangd relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified as compile_commands.json or, for simpler projects, a compile_flags.txt. For details on how to automatically generate one using CMake look [here](https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.html). Alternatively, you can use [Bear](https://github.com/rizsotto/Bear). **Snippet to enable the language server:** ```lua require'lspconfig'.clangd.setup{} ``` **Commands and default values:** ```lua Commands: - ClangdSwitchSourceHeader: Switch between source/header Default Values: capabilities = default capabilities, with offsetEncoding utf-8 cmd = { "clangd" } filetypes = { "c", "cpp", "objc", "objcpp" } root_dir = root_pattern("compile_commands.json", "compile_flags.txt", ".git") or dirname single_file_support = true ``` ## clarity_lsp `clarity-lsp` is a language server for the Clarity language. Clarity is a decidable smart contract language that optimizes for predictability and security. Smart contracts allow developers to encode essential business logic on a blockchain. To learn how to configure the clarity language server, see the [clarity-lsp documentation](https://github.com/hirosystems/clarity-lsp). **Snippet to enable the language server:** ```lua require'lspconfig'.clarity_lsp.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "clarity-lsp" } filetypes = { "clar", "clarity" } root_dir = root_pattern(".git") ``` ## clojure_lsp https://github.com/snoe/clojure-lsp Clojure Language Server **Snippet to enable the language server:** ```lua require'lspconfig'.clojure_lsp.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "clojure-lsp" } filetypes = { "clojure", "edn" } root_dir = root_pattern("project.clj", "deps.edn", "build.boot", "shadow-cljs.edn", ".git") ``` ## cmake https://github.com/regen100/cmake-language-server CMake LSP Implementation **Snippet to enable the language server:** ```lua require'lspconfig'.cmake.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "cmake-language-server" } filetypes = { "cmake" } init_options = { buildDirectory = "build" } root_dir = root_pattern(".git", "compile_commands.json", "build") or dirname single_file_support = true ``` ## codeqlls Reference: https://help.semmle.com/codeql/codeql-cli.html Binaries: https://github.com/github/codeql-cli-binaries **Snippet to enable the language server:** ```lua require'lspconfig'.codeqlls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: before_init = function(initialize_params) initialize_params['workspaceFolders'] = { { name = 'workspace', uri = initialize_params['rootUri'], }, } end, cmd = { "codeql", "execute", "language-server", "--check-errors", "ON_CHANGE", "-q" } filetypes = { "ql" } log_level = 2 root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end settings = { search_path = "list containing all search paths, eg: '~/codeql-home/codeql-repo'" } ``` ## crystalline https://github.com/elbywan/crystalline Crystal language server. **Snippet to enable the language server:** ```lua require'lspconfig'.crystalline.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "crystalline" } filetypes = { "crystal" } root_dir = root_pattern('shard.yml', '.git') or dirname single_file_support = true ``` ## csharp_ls https://github.com/razzmatazz/csharp-language-server Language Server for C#. csharp-ls requires the [dotnet-sdk](https://dotnet.microsoft.com/download) to be installed. The preferred way to install csharp-ls is with `dotnet tool install --global csharp-ls`. **Snippet to enable the language server:** ```lua require'lspconfig'.csharp_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "csharp-ls" } filetypes = { "cs" } init_options = { AutomaticWorkspaceInit = true } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end ``` ## cssls https://github.com/hrsh7th/vscode-langservers-extracted `css-languageserver` can be installed via `npm`: ```sh npm i -g vscode-langservers-extracted ``` Neovim does not currently include built-in snippets. `vscode-css-language-server` only provides completions when snippet support is enabled. To enable completion, install a snippet plugin and add the following override to your language client capabilities during setup. ```lua --Enable (broadcasting) snippet capability for completion local capabilities = vim.lsp.protocol.make_client_capabilities() capabilities.textDocument.completion.completionItem.snippetSupport = true require'lspconfig'.cssls.setup { capabilities = capabilities, } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.cssls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "vscode-css-language-server", "--stdio" } filetypes = { "css", "scss", "less" } root_dir = root_pattern("package.json", ".git") or bufdir settings = { css = { validate = true }, less = { validate = true }, scss = { validate = true } } single_file_support = true ``` ## cssmodules_ls https://github.com/antonk52/cssmodules-language-server Language server for autocompletion and go-to-definition functionality for CSS modules.

Example: ```lua vim.g.markdown_fenced_languages = { "ts=typescript" } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.denols.setup{} ``` **Commands and default values:** ```lua Commands: - DenolsCache: Cache a module and all of its dependencies. Default Values: cmd = { "deno", "lsp" } filetypes = { "javascript", "javascriptreact", "javascript.jsx", "typescript", "typescriptreact", "typescript.tsx" } handlers = { ["textDocument/definition"] = , ["textDocument/references"] = } init_options = { enable = true, lint = false, unstable = false } root_dir = root_pattern("deno.json", "deno.jsonc", "tsconfig.json", ".git") ``` ## dhall_lsp_server https://github.com/dhall-lang/dhall-haskell/tree/master/dhall-lsp-server language server for dhall `dhall-lsp-server` can be installed via cabal: ```sh cabal install dhall-lsp-server ``` prebuilt binaries can be found [here](https://github.com/dhall-lang/dhall-haskell/releases). **Snippet to enable the language server:** ```lua require'lspconfig'.dhall_lsp_server.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "dhall-lsp-server" } filetypes = { "dhall" } root_dir = root_pattern(".git") or dirname single_file_support = true ``` ## diagnosticls https://github.com/iamcco/diagnostic-languageserver Diagnostic language server integrate with linters. **Snippet to enable the language server:** ```lua require'lspconfig'.diagnosticls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "diagnostic-languageserver", "--stdio" } filetypes = Empty by default, override to add filetypes root_dir = Vim's starting directory single_file_support = true ``` ## dockerls https://github.com/rcjsuen/dockerfile-language-server-nodejs `docker-langserver` can be installed via `npm`: ```sh npm install -g dockerfile-language-server-nodejs ``` **Snippet to enable the language server:** ```lua require'lspconfig'.dockerls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "docker-langserver", "--stdio" } filetypes = { "dockerfile" } root_dir = root_pattern("Dockerfile") single_file_support = true ``` ## dotls https://github.com/nikeee/dot-language-server `dot-language-server` can be installed via `npm`: ```sh npm install -g dot-language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.dotls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "dot-language-server", "--stdio" } filetypes = { "dot" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end single_file_support = true ``` ## 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](https://github.com/mattn/efm-langserver/releases/tag/v0.0.38) to support launching the language server on single files. If on an older version of EFM, disable single file support: ```lua 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. ```lua require('lspconfig')['efm'].setup{ settings = ..., -- You must populate this according to the EFM readme filetypes = { 'python','cpp','lua' } } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.efm.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "efm-langserver" } root_dir = util.root_pattern(".git") single_file_support = true ``` ## elixirls https://github.com/elixir-lsp/elixir-ls `elixir-ls` can be installed by following the instructions [here](https://github.com/elixir-lsp/elixir-ls#building-and-running). ```bash 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. ```lua require'lspconfig'.elixirls.setup{ -- Unix cmd = { "/path/to/elixir-ls/language_server.sh" }; -- Windows cmd = { "/path/to/elixir-ls/language_server.bat" }; ... } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.elixirls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "elixir", "eelixir" } root_dir = root_pattern("mix.exs", ".git") or vim.loop.os_homedir() ``` ## elmls https://github.com/elm-tooling/elm-language-server#installation If you don't want to use Nvim to install it, then you can use: ```sh npm install -g elm elm-test elm-format @elm-tooling/elm-language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.elmls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "elm-language-server" } filetypes = { "elm" } init_options = { elmAnalyseTrigger = "change" } root_dir = root_pattern("elm.json") ``` ## ember https://github.com/lifeart/ember-language-server `ember-language-server` can be installed via `npm`: ```sh npm install -g @lifeart/ember-language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.ember.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "ember-language-server", "--stdio" } filetypes = { "handlebars", "typescript", "javascript" } root_dir = root_pattern("ember-cli-build.js", ".git") ``` ## emmet_ls https://github.com/aca/emmet-ls Package can be installed via `npm`: ```sh npm install -g emmet-ls ``` **Snippet to enable the language server:** ```lua require'lspconfig'.emmet_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "emmet-ls", "--stdio" } filetypes = { "html", "css" } root_dir = git root single_file_support = true ``` ## erlangls https://erlang-ls.github.io Language Server for Erlang. Clone [erlang_ls](https://github.com/erlang-ls/erlang_ls) Compile the project with `make` and copy resulting binaries somewhere in your $PATH eg. `cp _build/*/bin/* ~/local/bin` Installation instruction can be found [here](https://github.com/erlang-ls/erlang_ls). Installation requirements: - [Erlang OTP 21+](https://github.com/erlang/otp) - [rebar3 3.9.1+](https://github.com/erlang/rebar3) **Snippet to enable the language server:** ```lua require'lspconfig'.erlangls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "erlang_ls" } filetypes = { "erlang" } root_dir = root_pattern('rebar.config', 'erlang.mk', '.git') single_file_support = true ``` ## esbonio https://github.com/swyddfa/esbonio Esbonio is a language server for [Sphinx](https://www.sphinx-doc.org/en/master/) documentation projects. The language server can be installed via pip ``` pip install esbonio ``` Since Sphinx is highly extensible you will get best results if you install the language server in the same Python environment as the one used to build your documentation. To ensure that the correct Python environment is picked up, you can either launch `nvim` with the correct environment activated. ``` source env/bin/activate nvim ``` Or you can modify the default `cmd` to include the full path to the Python interpreter. ```lua require'lspconfig'.esbonio.setup { cmd = { '/path/to/virtualenv/bin/python', '-m', 'esbonio' } } ``` Esbonio supports a number of config values passed as `init_options` on startup, for example. ```lua require'lspconfig'.esbonio.setup { init_options = { server = { logLevel = "debug" }, sphinx = { confDir = "/path/to/docs", srcDir = "${confDir}/../docs-src" } } ``` A full list and explanation of the available options can be found [here](https://swyddfa.github.io/esbonio/docs/lsp/editors/index.html) **Snippet to enable the language server:** ```lua require'lspconfig'.esbonio.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "python3", "-m", "esbonio" } filetypes = { "rst" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end ``` ## eslint https://github.com/hrsh7th/vscode-langservers-extracted vscode-eslint-language-server: A linting engine for JavaScript / Typescript `vscode-eslint-language-server` can be installed via `npm`: ```sh npm i -g vscode-langservers-extracted ``` vscode-eslint-language-server provides an EslintFixAll command that can be used to format document on save ```vim autocmd BufWritePre EslintFixAll ``` See [vscode-eslint](https://github.com/microsoft/vscode-eslint/blob/55871979d7af184bf09af491b6ea35ebd56822cf/server/src/eslintServer.ts#L216-L229) for configuration options.

The code-formatting feature of the lsp can be controlled with the `provideFormatter` option. ```lua --Enable (broadcasting) snippet capability for completion local capabilities = vim.lsp.protocol.make_client_capabilities() capabilities.textDocument.completion.completionItem.snippetSupport = true require'lspconfig'.html.setup { capabilities = capabilities, } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.html.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "vscode-html-language-server", "--stdio" } filetypes = { "html" } init_options = { configurationSection = { "html", "css", "javascript" }, embeddedLanguages = { css = true, javascript = true }, provideFormatter = true } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end settings = {} single_file_support = true ``` ## idris2_lsp https://github.com/idris-community/idris2-lsp The Idris 2 language server. Plugins for the Idris 2 filetype include [Idris2-Vim](https://github.com/edwinb/idris2-vim) (fewer features, stable) and [Nvim-Idris2](https://github.com/ShinKage/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](https://aur.archlinux.org/packages/idris2-api-git/) and [Homebrew](https://formulae.brew.sh/formula/idris2#default). 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](https://github.com/idris-lang/Idris2/blob/main/INSTALL.md) 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:** ```lua require'lspconfig'.idris2_lsp.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "idris2-lsp" } filetypes = { "idris2" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end ``` ## intelephense https://intelephense.com/ `intelephense` can be installed via `npm`: ```sh npm install -g intelephense ``` **Snippet to enable the language server:** ```lua require'lspconfig'.intelephense.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "intelephense", "--stdio" } filetypes = { "php" } root_dir = root_pattern("composer.json", ".git") ``` ## java_language_server https://github.com/georgewfraser/java-language-server Java language server Point `cmd` to `lang_server_linux.sh` or the equivalent script for macOS/Windows provided by java-language-server **Snippet to enable the language server:** ```lua require'lspconfig'.java_language_server.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "java" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end settings = {} ``` ## 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](https://github.com/mfussenegger/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](http://download.eclipse.org/jdtls/snapshots/?d) 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](https://github.com/direnv/direnv) is highly recommended. ```bash # 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 ``` ```lua -- init.lua require'lspconfig'.jdtls.setup{} ``` For automatic installation you can use the following unofficial installers/launchers under your own risk: - [jdtls-launcher](https://github.com/eruizc-dev/jdtls-launcher) (Includes lombok support by default) ```lua -- init.lua require'lspconfig'.jdtls.setup{ cmd = { 'jdtls' } } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.jdtls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "/usr/lib/jvm/temurin-11-jdk-amd64/bin/java", "-Declipse.application=org.eclipse.jdt.ls.core.id1", "-Dosgi.bundles.defaultStartLevel=4", "-Declipse.product=org.eclipse.jdt.ls.core.product", "-Dlog.protocol=true", "-Dlog.level=ALL", "-Xms1g", "-Xmx2G", "--add-modules=ALL-SYSTEM", "--add-opens", "java.base/java.util=ALL-UNNAMED", "--add-opens", "java.base/java.lang=ALL-UNNAMED", "-jar", "/plugins/org.eclipse.equinox.launcher_*.jar", "-configuration", "config_linux", "-data", "/home/runner/workspace" } filetypes = { "java" } handlers = { ["language/status"] = , ["textDocument/codeAction"] = , ["textDocument/rename"] = , ["workspace/applyEdit"] = } init_options = { jvm_args = {}, workspace = "/home/runner/workspace" } root_dir = { -- Single-module projects { 'build.xml', -- Ant 'pom.xml', -- Maven 'settings.gradle', -- Gradle 'settings.gradle.kts', -- Gradle }, -- Multi-module projects { 'build.gradle', 'build.gradle.kts' }, } or vim.fn.getcwd() single_file_support = true ``` ## jedi_language_server https://github.com/pappasam/jedi-language-server `jedi-language-server`, a language server for Python, built on top of jedi **Snippet to enable the language server:** ```lua require'lspconfig'.jedi_language_server.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "jedi-language-server" } filetypes = { "python" } root_dir = vim's starting directory single_file_support = true ``` ## jsonls https://github.com/hrsh7th/vscode-langservers-extracted vscode-json-language-server, a language server for JSON and JSON schema `vscode-json-language-server` can be installed via `npm`: ```sh npm i -g vscode-langservers-extracted ``` Neovim does not currently include built-in snippets. `vscode-json-language-server` only provides completions when snippet support is enabled.

Omnisharp can also be built from source by following the instructions [here](https://github.com/omnisharp/omnisharp-roslyn#downloading-omnisharp). Omnisharp requires the [dotnet-sdk](https://dotnet.microsoft.com/download) 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. ```lua 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: ```bash find /path/to/omnisharp-osx | xargs xattr -r -d com.apple.quarantine ``` **Snippet to enable the language server:** ```lua require'lspconfig'.omnisharp.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "cs", "vb" } init_options = {} on_new_config = function(new_config, new_root_dir) if new_root_dir then table.insert(new_config.cmd, '-s') table.insert(new_config.cmd, new_root_dir) end end, root_dir = root_pattern(".sln") or root_pattern(".csproj") ``` ## opencl_ls https://github.com/Galarius/opencl-language-server Build instructions can be found [here](https://github.com/Galarius/opencl-language-server/blob/main/_dev/build.md). Prebuilt binaries are available for Linux, macOS and Windows [here](https://github.com/Galarius/opencl-language-server/releases). **Snippet to enable the language server:** ```lua require'lspconfig'.opencl_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "opencl-language-server" } filetypes = { "opencl" } root_dir = util.root_pattern(".git") ``` ## openscad_ls https://github.com/dzhu/openscad-language-server A Language Server Protocol server for OpenSCAD You can build and install `openscad-language-server` binary with `cargo`: ```sh cargo install openscad-language-server ``` Vim does not have built-in syntax for the `openscad` filetype currently. This can be added via an autocmd: ```lua vim.cmd [[ autocmd BufRead,BufNewFile *.scad set filetype=openscad ]] ``` or by installing a filetype plugin such as https://github.com/sirtaj/vim-openscad **Snippet to enable the language server:** ```lua require'lspconfig'.openscad_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "openscad-language-server" } filetypes = { "openscad" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end single_file_support = true ``` ## pasls https://github.com/genericptr/pascal-language-server An LSP server implementation for Pascal variants that are supported by Free Pascal, including Object Pascal. It uses CodeTools from Lazarus as backend. First set `cmd` to the Pascal lsp binary. Customization options are passed to pasls as environment variables for example in your `.bashrc`: ```bash export FPCDIR='/usr/lib/fpc/src' # FPC source directory (This is the only required option for the server to work). export PP='/usr/lib/fpc/3.2.2/ppcx64' # Path to the Free Pascal compiler executable. export LAZARUSDIR='/usr/lib/lazarus' # Path to the Lazarus sources. export FPCTARGET='' # Target operating system for cross compiling. export FPCTARGETCPU='x86_64' # Target CPU for cross compiling. ``` **Snippet to enable the language server:** ```lua require'lspconfig'.pasls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "pasls" } filetypes = { "pascal" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end single_file_support = true ``` ## perlls https://github.com/richterger/Perl-LanguageServer/tree/master/clients/vscode/perl `Perl-LanguageServer`, a language server for Perl.

You have to install the language server manually. Clone the PerlNavigator repo, install based on the [instructions](https://github.com/bscan/PerlNavigator#installation-for-other-editors), and point `cmd` to `server.js` inside the `server/out` directory: ```lua cmd = {'node', '/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: ```lua 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. **Snippet to enable the language server:** ```lua require'lspconfig'.perlnavigator.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = {} filetypes = { "perl" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end single_file_support = true ``` ## perlpls https://github.com/FractalBoy/perl-language-server https://metacpan.org/pod/PLS `PLS`, another language server for Perl.

The `plz` binary will automatically install the LSP for you on first run **Snippet to enable the language server:** ```lua require'lspconfig'.please.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "plz", "tool", "lps" } filetypes = { "bzl" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end single_file_support = true ``` ## powershell_es https://github.com/PowerShell/PowerShellEditorServices Language server for PowerShell. To install, download and extract PowerShellEditorServices.zip from the [releases](https://github.com/PowerShell/PowerShellEditorServices/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. ```lua 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`. ```lua 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](https://github.com/PowerShell/PowerShellEditorServices#stdio) to learn more. ```lua require'lspconfig'.powershell_es.setup{ cmd = {'pwsh', '-NoLogo', '-NoProfile', '-Command', "c:/PSES/Start-EditorServices.ps1 ..."} } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.powershell_es.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "ps1" } on_new_config = function(new_config, _) -- Don't overwrite cmd if already set if not new_config.cmd then new_config.cmd = make_cmd(new_config) end end, root_dir = git root or current directory shell = "pwsh" single_file_support = true ``` ## prismals Language Server for the Prisma JavaScript and TypeScript ORM `@prisma/language-server` can be installed via npm ```sh npm install -g @prisma/language-server ``` **Snippet to enable the language server:** ```lua require'lspconfig'.prismals.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "prisma-language-server", "--stdio" } filetypes = { "prisma" } root_dir = root_pattern(".git", "package.json") settings = { prisma = { prismaFmtBinPath = "" } } ``` ## psalm https://github.com/vimeo/psalm Can be installed with composer. ```sh composer global require vimeo/psalm ``` **Snippet to enable the language server:** ```lua require'lspconfig'.psalm.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "psalm-language-server" } filetypes = { "php" } root_dir = root_pattern("psalm.xml", "psalm.xml.dist") ``` ## puppet LSP server for Puppet.

You have to install the language server manually. You can install reason language server from [reason-language-server](https://github.com/jaredly/reason-language-server) repository. ```lua cmd = {''} ``` **Snippet to enable the language server:** ```lua require'lspconfig'.reason_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "reason-language-server" } filetypes = { "reason" } root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end ``` ## remark_ls https://github.com/remarkjs/remark-language-server `remark-language-server` can be installed via `npm`: ```sh npm install -g remark-language-server ``` `remark-language-server` uses the same [configuration files](https://github.com/remarkjs/remark/tree/main/packages/remark-cli#example-config-files-json-yaml-js) as `remark-cli`. This uses a plugin based system. Each plugin needs to be installed locally using `npm` or `yarn`. For example, given the following `.remarkrc.json`: ```json { "presets": [ "remark-preset-lint-recommended" ] } ``` `remark-preset-lint-recommended` needs to be installed in the local project: ```sh npm install remark-preset-lint-recommended ``` **Snippet to enable the language server:** ```lua require'lspconfig'.remark_ls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "remark-language-server", "--stdio" } filetypes = { "markdown" } root_dir = function(path) -- Support git directories and git files (worktrees) if M.path.is_dir(M.path.join(path, '.git')) or M.path.is_file(M.path.join(path, '.git')) then return path end end) end single_file_support = true ``` ## 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](https://github.com/rescript-lang/vim-rescript) repo. Clone the vim-rescript repo and point `cmd` to `server.js` inside `server/out` directory: ```lua cmd = {'node', '/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: ```lua 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](https://github.com/rescript-lang/rescript-vscode/releases).

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. ```lua -- 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 { cmd = {vls_binary}, } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.vls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "vlang" } root_dir = root_pattern("v.mod", ".git") ``` ## volar https://github.com/johnsoncodehk/volar/tree/master/packages/vue-language-server Volar language server for Vue Volar can be installed via npm: ```sh npm install -g @volar/vue-language-server ``` Volar by default supports Vue 3 projects. Vue 2 projects need [additional configuration](https://github.com/johnsoncodehk/volar/blob/master/extensions/vscode-vue-language-features/README.md?plain=1#L28-L63). **Take Over Mode** Volar can serve as a language server for both Vue and TypeScript via [Take Over Mode](https://github.com/johnsoncodehk/volar/discussions/471). To enable Take Over Mode, override the default filetypes in `setup{}` as follows: ```lua 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 ```lua 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 ```lua 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{ on_new_config = function(new_config, new_root_dir) new_config.init_options.typescript.serverPath = get_typescript_server_path(new_root_dir) end, } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.volar.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "vue-language-server", "--stdio" } filetypes = { "vue" } init_options = { documentFeatures = { documentColor = false, documentFormatting = { defaultPrintWidth = 100 }, documentSymbol = true, foldingRange = true, linkedEditingRange = true, selectionRange = true }, languageFeatures = { callHierarchy = true, codeAction = true, codeLens = true, completion = { defaultAttrNameCase = "kebabCase", defaultTagNameCase = "both" }, definition = true, diagnostics = true, documentHighlight = true, documentLink = true, hover = true, implementation = true, references = true, rename = true, renameFileRefactoring = true, schemaRequestService = true, semanticTokens = false, signatureHelp = true, typeDefinition = true }, typescript = { serverPath = "" } } on_new_config = function(new_config, new_root_dir) if new_config.init_options and new_config.init_options.typescript and new_config.init_options.typescript.serverPath == '' then new_config.init_options.typescript.serverPath = get_typescript_server_path(new_root_dir) end end, root_dir = function(startpath) return M.search_ancestors(startpath, matcher) end ``` ## vuels https://github.com/vuejs/vetur/tree/master/server Vue language server(vls) `vue-language-server` can be installed via `npm`: ```sh npm install -g vls ``` **Snippet to enable the language server:** ```lua require'lspconfig'.vuels.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "vls" } filetypes = { "vue" } init_options = { config = { css = {}, emmet = {}, html = { suggest = {} }, javascript = { format = {} }, stylusSupremacy = {}, typescript = { format = {} }, vetur = { completion = { autoImport = false, tagCasing = "kebab", useScaffoldSnippets = false }, format = { defaultFormatter = { js = "none", ts = "none" }, defaultFormatterOptions = {}, scriptInitialIndent = false, styleInitialIndent = false }, useWorkspaceDependencies = false, validation = { script = true, style = true, template = true } } } } root_dir = root_pattern("package.json", "vue.config.js") ``` ## yamlls https://github.com/redhat-developer/yaml-language-server `yaml-language-server` can be installed via `yarn`: ```sh 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= ``` 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. ```lua 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](https://github.com/redhat-developer/yaml-language-server/issues/211). * [#307](https://github.com/redhat-developer/yaml-language-server/issues/307). To override a schema to use a specific k8s schema version (for example, to use 1.18): ```lua 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 }, }, } } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.yamlls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "yaml-language-server", "--stdio" } filetypes = { "yaml", "yaml.docker-compose" } root_dir = util.find_git_ancestor settings = { redhat = { telemetry = { enabled = false } } } single_file_support = true ``` ## 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. ```lua require'lspconfig'.zeta_note.setup{ cmd = {'path/to/zeta-note'} } ``` **Snippet to enable the language server:** ```lua require'lspconfig'.zeta_note.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: filetypes = { "markdown" } root_dir = root_pattern(".zeta.toml") ``` ## zk github.com/mickael-menu/zk A plain text note-taking assistant **Snippet to enable the language server:** ```lua require'lspconfig'.zk.setup{} ``` **Commands and default values:** ```lua Commands: - ZkIndex: Index - ZkNew: ZkNew Default Values: cmd = { "zk", "lsp" } filetypes = { "markdown" } root_dir = root_pattern(".zk") ``` ## zls https://github.com/zigtools/zls `Zig LSP implementation + Zig Language Server`. **Snippet to enable the language server:** ```lua require'lspconfig'.zls.setup{} ``` **Commands and default values:** ```lua Commands: Default Values: cmd = { "zls" } filetypes = { "zig", "zir" } root_dir = util.root_pattern("zls.json", ".git") or current_file_dirname single_file_support = true ``` vim:ft=markdown
