Overview (`README.md`)

nvim-lspconfig

nvim-lspconfig is a collection of LSP server configurations for the Nvim LSP client.

View all configs, or run :help lspconfig-all from Nvim.

Important ⚠️

  • require('lspconfig') (the legacy "framework" of nvim-lspconfig) is deprecated in favor of vim.lsp.config (Nvim 0.11+).
    • The lspconfig.lua module will be dropped. Calls to require('lspconfig') will show a warning, which will later become an error.
  • nvim-lspconfig itself is NOT deprecated. It provides server-specific configs.
    • The configs live in the lsp/ directory. vim.lsp.config automatically finds them and merges them with any local lsp/*.lua configs defined by you or a plugin.
    • The old configs in lua/lspconfig/ are deprecated and will be removed.

Migration instructions

  1. Upgrade to Nvim 0.11+
  2. (Optional) Use vim.lsp.config('…') (not require'lspconfig'.….setup{}) to customize or define a config.
  3. Use vim.lsp.enable('…') (not require'lspconfig'.….setup{}) to enable a config, so that it activates for its filetypes.

Support

These configs are best-effort and supported by the community (you). See contributions.

Install

  • Requires Nvim 0.11.3+.
    • Support for Nvim 0.10 will be removed. Upgrade Nvim and nvim-lspconfig before reporting an issue.
  • With Nvim 0.12+, you can use the builtin vim.pack plugin manager:
    lua
    vim.pack.add{
  { src = 'https://github.com/neovim/nvim-lspconfig' },
}
  • Or install nvim-lspconfig using Vim's "packages" feature:
    text
    git clone https://github.com/neovim/nvim-lspconfig ~/.config/nvim/pack/nvim/start/nvim-lspconfig
  • Or use a 3rd-party plugin manager.

Quickstart

  1. Install a language server, e.g. pyright
    bash
    npm i pyright
  2. Enable its config in your init.lua (:help lsp-quickstart).
    lua
    vim.lsp.enable('pyright')
  3. Ensure your project/workspace contains a root marker as specified in :help lspconfig-all.
  4. Open a code file in Nvim. LSP will attach and provide diagnostics.
    text
    nvim main.py
  5. Run :checkhealth vim.lsp to see the status or to troubleshoot.

See :help lspconfig-all for the full list of server-specific details. For
servers not on your $PATH (e.g., jdtls, elixirls), you must manually set
the cmd parameter:

lua
vim.lsp.config('jdtls', {
  cmd = { '/path/to/jdtls' },
})

Commands

  • :LspInfo (alias to :checkhealth vim.lsp) shows the status of active and configured language servers.
  • :lsp enable [<config_name>] (:LspStart for Nvim 0.11 or older) Start the requested server name. Will only successfully start if the command detects a root directory matching the current config.
  • :lsp disable [<config_name>] (:LspStop for Nvim 0.11 or older) Stops the given server. Defaults to stopping all servers active on the current buffer. To force stop use :LspStop!
  • :lsp restart [<client_name>] (:LspRestart for Nvim 0.11 or older) Restarts the given client, and attempts to reattach to all previously attached buffers. Defaults to restarting all active servers.

Configuration

Nvim sets default options and mappings when LSP is active in a buffer:

To customize, see:

Extra settings can be specified for each LSP server. With Nvim 0.11+ you can
extend a config by calling
vim.lsp.config('…', {…}).

lua
vim.lsp.config('rust_analyzer', {
  -- Server-specific settings. See `:help lsp-quickstart`
  settings = {
    ['rust-analyzer'] = {},
  },
})

Config priority

Configs are sourced in this order:

  1. lsp/ in 'runtimepath'
  2. after/lsp/ in 'runtimepath'
  3. vim.lsp.config()

If you install nvim-lspconfig or similar plugins, the order that configs are applied depends on the load order. To ensure that your own config "wins" and overrides the others, use after/lsp/ and/or vim.lsp.config() to override/extend the defaults.

Creating a config

As code

  1. Run :lua vim.lsp.config('foo', {cmd={'true'}})
  2. Run :lua vim.lsp.enable('foo')
  3. Run :checkhealth vim.lsp, the new config is listed under "Enabled Configurations". 😎

As a file

  1. Create a file after/lsp/foo.lua somewhere on your 'runtimepath'.
    text
    :exe 'edit' stdpath('config') .. '/after/lsp/foo.lua'
  2. Add this code to the file (or copy any of the examples from the lsp/ directory in this repo):
    text
    return {
  cmd = { 'true' },
}
  3. Save the file (with ++p to ensure its parent directory is created).
    text
    :write ++p
  4. Enable the config.
    text
    :lua vim.lsp.enable('foo')
  5. Run :checkhealth vim.lsp, the new config is listed under "Enabled Configurations". 🌈

LSP Settings Type Annotations

nvim-lspconfig generates Lua type definitions for each supported LSP server.
By manually adding annotations (e.g., ---@type lspconfig.settings.server_name),
you enable auto-completion and diagnostics for your server settings.

Example:

lua
---@type vim.lsp.Config
local config = {
  ---@type lspconfig.settings.lua_ls
  settings = {
    Lua = {
      runtime = {
        version = 'LuaJIT',
      },
      workspace = {
        preloadFileSize = 10000,
        library = {
          vim.env.VIMRUNTIME,
        }
      },
    },
  },
}

vim.lsp.config('lua_ls', config)

Troubleshooting

Start with :checkhealth vim.lsp to troubleshoot. The most common reasons a language server does not start or attach are:

  1. Language server is not installed. nvim-lspconfig does not install language servers for you. You should be able to run the cmd defined in the config from the command line and see that the language server starts. If the cmd is a name instead of an absolute path, ensure it is on your $PATH.

  2. Missing filetype plugins. Some languages are not detected by Nvim because they have not yet been added to the filetype detection system. Ensure :set filetype? shows the filetype and not an empty value.

  3. Not triggering root detection. Some language servers require a "workspace", which is found by looking for an ancestor directory that contains a "root marker". The most common root marker is .git/, but each config defines other "root marker" names. Root markers/directories are listed in :help lspconfig-all.

    You can also explicitly set a root instead of relying on automatic detection by enabling 'exrc' and adding an .nvim.lua at the desired root dir with the following code:

    lua
    vim.lsp.config('<client name>', {
  root_dir = vim.fn.fnamemodify(debug.getinfo(1, 'S').source:sub(2), ':p:h'),
})

    Note that prior to nvim 0.12 exrc file is executed only if it's inside of a cwd where you start nvim.

Bug reports

If you found a bug with LSP functionality, report it to Neovim core.

Before reporting a bug, check your logs and the output of :checkhealth vim.lsp. Add this to your init.lua to enable verbose logging:

lua
vim.lsp.log.set_level('debug')

Attempt to run the language server, then run :LspLog to open the log.
Most of the time, the reason for failure is present in the logs.

Contributions

If a language server is missing from configs.md, contributing
a new configuration for it helps others, especially if the server requires special setup. Follow these steps:

  1. Read CONTRIBUTING.md.
  2. Create a new file at lsp/<server_name>.lua.
  3. Ask questions on GitHub Discussions or in the Neovim Matrix room.

Release process

To publish a release:

  • Create and push a new tag.
  • After pushing the tag, a GitHub action
    will automatically package the plugin and publish the release to LuaRocks.

arduino_language_server

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

Language server for Arduino

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

text
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.

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

If you don't have a sketch yet create one.

sh
$ arduino-cli sketch new test
$ cd test

You will need a sketch.yaml file in order for the language server to understand your project. It will also save you passing options to arduino-cli each time you compile or upload a file. You can generate the file by using the following commands.

First gather some information about your board. Make sure your board is connected and run the following:

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

Then generate the file:

sh
arduino-cli board attach -p /dev/ttyACM0 -b arduino:avr:uno test.ino

The resulting file should look like this:

yaml
default_fqbn: arduino:avr:uno
default_port: /dev/ttyACM0

Your folder structure should look like this:

text
.
├── test.ino
└── sketch.yaml

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

Note that an upstream bug makes keywords in some cases become undefined by the language server.
Ref: https://github.com/arduino/arduino-ide/issues/159

Snippet to enable the language server:

lua
vim.lsp.enable('arduino_language_server')

Default config:

  • capabilities :
    lua
    {
  textDocument = {
    semanticTokens = vim.NIL
  },
  workspace = {
    semanticTokens = vim.NIL
  }
}
  • cmd :
    lua
    { "arduino-language-server" }
  • filetypes :
    lua
    { "arduino" }
  • root_dir: ../lsp/arduino_language_server.lua:74

armls

https://github.com/arm/armls

ArmLS is a language server for Arm Assembly.

It supports A32 and A64 assembly and provides hover documentation,
completion, diagnostics, document symbols, go-to-definition, and
semantic highlighting.

ArmLS can be installed from the Arm Assembly Support extension on
Open VSX or the Visual Studio Marketplace.

The internal diagnostics engine is currently alpha quality. Arm
recommends disabling some operand diagnostics by default and using
clang-powered diagnostics when appropriate.

Snippet to enable the language server:

lua
vim.lsp.enable('armls')

Default config:

  • cmd :
    lua
    { "armls" }
  • filetypes :
    lua
    { "asm" }
  • settings :
    lua
    {
  armls = {
    diagnostics = {
      disableCategories = { "invalidOperand", "tooManyOperands", "tooFewOperands" },
      enable = true
    }
  }
}

asm_lsp

https://github.com/bergercookie/asm-lsp

Language Server for NASM/GAS/GO Assembly

asm-lsp can be installed via cargo:
cargo install asm-lsp

Snippet to enable the language server:

lua
vim.lsp.enable('asm_lsp')

Default config:

  • cmd :
    lua
    { "asm-lsp" }
  • filetypes :
    lua
    { "asm", "vmasm" }
  • root_markers :
    lua
    { ".asm-lsp.toml", ".git" }

ast_grep

https://ast-grep.github.io/

ast-grep(sg) is a fast and polyglot tool for code structural search, lint, rewriting at large scale.
ast-grep LSP only works in projects that have sgconfig.y[a]ml in their root directories.

sh
npm install [-g] @ast-grep/cli

Snippet to enable the language server:

lua
vim.lsp.enable('ast_grep')

Default config:

  • cmd :
    lua
    { "ast-grep", "lsp" }
  • filetypes :
    lua
    { "bash", "c", "cpp", "cs", "css", "elixir", "go", "haskell", "html", "java", "javascript", "javascriptreact", "json", "kotlin", "lua", "nix", "php", "python", "ruby", "rust", "scala", "sh", "solidity", "swift", "typescript", "typescriptreact", "yaml" }
  • reuse_client: ../lsp/ast_grep.lua:12
  • root_markers :
    lua
    { "sgconfig.yaml", "sgconfig.yml" }
  • workspace_required : true

astro

https://github.com/withastro/astro/tree/main/packages/language-tools/language-server

astro-ls can be installed via npm:

sh
npm install @astrojs/language-server

If typescript is installed globally, you might get the \typescript.tsdk` init option is required` error.
You will need to manually pass the typescript SDK path. Here is an example of a Nix configuration where typescript is installed via Nix's Home-manager:

nix
{ config, pkgs, ... }:

{
  home.packages = with pkgs; [
    typescript
  ];

  programs.neovim = {
    plugins = with pkgs.vimPlugins; [
      nvim-lspconfig
    ];
    extraPackages = with pkgs; [
      astro-language-server
    ];
    initLua = ''
      vim.lsp.config['astro'] = {
        init_options = {
          typescript = {
            tsdk = ${pkgs.typescript}/lib/node_modules/typescript/lib,
          },
        },
      }

      vim.lsp.enable('astro')

      -- ...
    '';
  };
}

The path can also be passed via a variable, like vim.g.tsdk = "${pkgs.typescript}/lib/node_modules/typescript/lib" and then used in the Lua Neovim config.

WARNING: TypeScript 7.x dropped tsserverlibrary.js from its npm package, so
typescript.tsdk cannot resolve from a local or global TS 7.x install. Pin to
TS <= 6.x (e.g. npm install typescript@~6) for the LSP to start.

For a globally-installed TS (resolved at runtime, unlike the Nix example where the
path is known at build time), look up the workspace-local TS first via
util.get_typescript_server_path, then fall back to npm root -g:

lua
vim.lsp.config('astro', {
  before_init = function(_, config)
    local util = require('lspconfig.util')
    local tsdk = util.get_typescript_server_path(config.root_dir)
    if tsdk == '' then
      local npm_root = vim.fn.systemlist('npm root -g')
      if vim.v.shell_error == 0 and npm_root[1] then
        tsdk = npm_root[1] .. '/typescript/lib'
      end
    end
    config.init_options = config.init_options or {}
    config.init_options.typescript = config.init_options.typescript or {}
    config.init_options.typescript.tsdk = tsdk
  end,
})
vim.lsp.enable('astro')

For other package managers, replace npm root -g with:

  • pnpm: pnpm root -g
  • yarn classic: yarn global dir .. /node_modules
  • yarn berry (>=2): globals unsupported — use a workspace-local TS instead

Snippet to enable the language server:

lua
vim.lsp.enable('astro')

Default config:

  • before_init: ../lsp/astro.lua:82
  • cmd: ../lsp/astro.lua:82
  • filetypes :
    lua
    { "astro" }
  • init_options :
    lua
    {
  typescript = {}
}
  • root_markers :
    lua
    { "package.json", "tsconfig.json", "jsconfig.json", ".git" }

atlas

https://github.com/ariga/atlas

Language server for Atlas config and schema files.

You may also need to configure the filetype for *.hcl files:

vim
autocmd BufNewFile,BufRead atlas.hcl set filetype=atlas-config
autocmd BufNewFile,BufRead *.my.hcl set filetype=atlas-schema-mysql
autocmd BufNewFile,BufRead *.pg.hcl set filetype=atlas-schema-postgresql
autocmd BufNewFile,BufRead *.lt.hcl set filetype=atlas-schema-sqlite
autocmd BufNewFile,BufRead *.ch.hcl set filetype=atlas-schema-clickhouse
autocmd BufNewFile,BufRead *.ms.hcl set filetype=atlas-schema-mssql
autocmd BufNewFile,BufRead *.rs.hcl set filetype=atlas-schema-redshift
autocmd BufNewFile,BufRead *.test.hcl set filetype=atlas-test
autocmd BufNewFile,BufRead *.plan.hcl set filetype=atlas-plan
autocmd BufNewFile,BufRead *.rule.hcl set filetype=atlas-rule

or

lua
vim.filetype.add({
  filename = {
    ['atlas.hcl'] = 'atlas-config',
  },
  pattern = {
    ['.*/*.my.hcl'] = 'atlas-schema-mysql',
    ['.*/*.pg.hcl'] = 'atlas-schema-postgresql',
    ['.*/*.lt.hcl'] = 'atlas-schema-sqlite',
    ['.*/*.ch.hcl'] = 'atlas-schema-clickhouse',
    ['.*/*.ms.hcl'] = 'atlas-schema-mssql',
    ['.*/*.rs.hcl'] = 'atlas-schema-redshift',
    ['.*/*.test.hcl'] = 'atlas-test',
    ['.*/*.plan.hcl'] = 'atlas-plan',
    ['.*/*.rule.hcl'] = 'atlas-rule',
  },
})

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:

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"
vim.lsp.config('bicep', {
    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 \

denols

https://github.com/denoland/deno

Deno's built-in language server

To appropriately highlight codefences returned from denols, you will need to augment vim.g.markdown_fenced languages
in your init.lua. Example:

lua
vim.g.markdown_fenced_languages = {
  "ts=typescript"
}

Some care must be taken here to correctly infer whether a file is part of a Deno program, or a TS program that
expects to run in Node or Web Browsers. This supports having a Deno module that is a part of a mostly-not-Deno
monorepo. We do this by finding the nearest package manager lock file, and the nearest deno.json or deno.jsonc.
Note that this means that without a deno.json, deno.jsonc, or deno.lock file, this LSP client will not attach.

Example:

text
project-root
+-- node_modules/...
+-- package-lock.json
+-- package.json
+-- packages
    +-- deno-module
    |   +-- deno.json
    |   +-- package.json <-- It's normal for Deno projects to have package.json files!
    |   +-- src
    |       +-- index.ts <-- this is a Deno file
    +-- node-module
        +-- package.json
        +-- src
            +-- index.ts <-- a non-Deno file (ie, should use ts_ls or tsgo)

From the file being edited, we walk up to find the nearest package manager lockfile. This is PROJECT ROOT.
From the file being edited, find the nearest deno.json or deno.jsonc. This is DENO ROOT.
From the file being edited, find the nearest deno.lock. This is DENO LOCK ROOT
If DENO LOCK ROOT is found, and PROJECT ROOT is missing or shorter, then this is a deno file, and we attach.
If DENO ROOT is found, and it's longer than or equal to PROJECT ROOT, then this is a Deno file, and we attach.
Otherwise, we abort, because this is a non-Deno TS file.

Snippet to enable the language server:

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.

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 vim.lsp.config. Otherwise the server will be launch on the BufEnter instead
of the FileType autocommand, and the filetype variable used to populate the languageId will not yet be set.

lua
vim.lsp.config('efm', {
  filetypes = { 'python','cpp','lua' }
  settings = ..., -- You must populate this according to the EFM readme
})

elixirls

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

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

  1. Download the zip from https://github.com/elixir-lsp/elixir-ls/releases/latest/
  2. Unzip it and make it executable.
    bash
    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
vim.lsp.config('elixirls', {
    -- Unix
    cmd = { "/path/to/elixir-ls/language_server.sh" };
    -- Windows
    cmd = { "/path/to/elixir-ls/language_server.bat" };
    ...
})

'root_dir' is chosen like this: if two or more directories containing mix.exs were found when searching
directories upward, the second one (higher up) is chosen, with the assumption that it is the root of an umbrella
app. Otherwise the directory containing the single mix.exs that was found is chosen.

Snippet to enable the language server:

eslint

https://github.com/hrsh7th/vscode-langservers-extracted

vscode-eslint-language-server is a linting engine for JavaScript / Typescript.
It can be installed via npm:

sh
npm i vscode-langservers-extracted

The default on_attach config provides the LspEslintFixAll command that can be used to format a document on save:

lua
local base_on_attach = vim.lsp.config.eslint.on_attach
vim.lsp.config("eslint", {
  on_attach = function(client, bufnr)
    if not base_on_attach then return end

    base_on_attach(client, bufnr)
    vim.api.nvim_create_autocmd("BufWritePre", {
      buffer = bufnr,
      command = "LspEslintFixAll",
    })
  end,
})

See vscode-eslint for configuration options.

Messages handled in lspconfig: eslint/openDoc, eslint/confirmESLintExecution, eslint/probeFailed, eslint/noLibrary

Additional messages you can handle: eslint/noConfig

Monorepo support

vscode-eslint-language-server supports monorepos by default. It will automatically find the config file corresponding to the package you are working on. You can use different configs in different packages.
This works without the need of spawning multiple instances of vscode-eslint-language-server.
You can use a different version of ESLint in each package, but it is recommended to use the same version of ESLint in all packages. The location of the ESLint binary will be determined automatically.

/!\ When using flat config files, you need to use them across all your packages in your monorepo, as it's a global setting for the server.

Flat config in ESLint versions prior to 10.0

If you're using a ESLint version that supports both flat config and eslintrc (>= 8.21, < 10.0) and want to change
the default behavior, you'll need to set
experimental.useFlatConfig accordingly:

lua
vim.lsp.config("eslint", {
  settings = {
    experimental = {
      -- If you want to use flat config on >= 8.21, < 9.0
      useFlatConfig = true,
      -- Or if you want to use eslintrc on 9.*
      -- useFlatConfig = false,
    }
  }
})

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:

lua
vim.lsp.enable('idris2_lsp')

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

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.

lua
-- init.lua
  vim.lsp.enable('jdtls')

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:

sh
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:

where ~/.julia/environments/nvim-lspconfig is the location where
the default configuration expects LanguageServer.jl to be installed.

To update an existing install, use the following command:

sh
julia --project=~/.julia/environments/nvim-lspconfig -e 'using Pkg; Pkg.update()'

Note: In order to have LanguageServer.jl pick up installed packages or dependencies in a
Julia project, you must make sure that the project is instantiated:

sh
julia --project=/path/to/my/project -e 'using Pkg; Pkg.instantiate()'

To activate a Julia environment, use the :LspJuliaActivateEnv command. A prompt will ask you to select a Julia
environment from the list of environments found in the current working directory and the environments/ folder of
$JULIA_DEPOT_PATH entries. You can also provide a path to a Julia environment directly.
Example: :LspJuliaActivateEnv /path/to/my/project.

providers, and for Azure Verified Modules.

Only covers Microsoft providers, so it is intended to run alongside
terraformls.

Download a released binary from
https://github.com/Azure/ms-terraform-lsp/releases.

Snippet to enable the language server:

lua
vim.lsp.enable('ms_terraform_lsp')

Default config:

  • cmd :
    lua
    { "ms-terraform-lsp", "serve" }
  • filetypes :
    lua
    { "terraform" }
  • root_markers :
    lua
    { ".terraform", ".git" }

msbuild_project_tools_server

https://github.com/tintoy/msbuild-project-tools-server/

MSBuild Project Tools Server can be installed by following the README.MD on the above repository.

Example config:

lua
vim.lsp.config('msbuild_project_tools_server', {
  cmd = {'dotnet', '/path/to/server/MSBuildProjectTools.LanguageServer.Host.dll'}
})

There's no builtin filetypes for msbuild files, would require some filetype aliases:

lua
vim.filetype.add({
  extension = {
    props = 'msbuild',
    tasks = 'msbuild',
    targets = 'msbuild',
  },
  pattern = {
    [ [[.*\..*proj]] ] = 'msbuild',
  },
})

Optionally tell treesitter to treat msbuild as xml so you can get syntax highlighting if you have the treesitter-xml-parser installed.

lua
vim.treesitter.language.register('xml', { 'msbuild' })

Snippet to enable the language server:

lua
vim.lsp.enable('msbuild_project_tools_server')

nelua_lsp

https://github.com/codehz/nelua-lsp

nelua-lsp is an experimental nelua language server.

You need nelua.vim for nelua files to be recognized or add this to your config:

in vimscript:

vimscript
au BufNewFile,BufRead *.nelua setf nelua

in lua:

lua
vim.api.nvim_create_autocmd({ "BufNewFile", "BufRead" }, { pattern = { "*.nelua" }, command = "setf nelua"})

By default, nelua-lsp 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
vim.lsp.config('nelua_lsp', {
    cmd = { "nelua", "-L", "/path/to/nelua-lsp/", "--script", "/path/to/nelua-lsp/nelua-lsp.lua" },
})

Snippet to enable the language server:

lua
vim.lsp.enable('nelua_lsp')
