nvim-lspconfig

nvim-lspconfig is a "data only" repo, providing basic, default Nvim LSP client configurations for various LSP servers. View all configs or :help lspconfig-all from Nvim.

Important ⚠️

• These configs are best-effort and supported by the community (you). See contributions.
• The configs live in lsp/.
  • Upgrade to Nvim 0.11+ and use vim.lsp.enable('…') (not require'…'.pyright.setup{}) to enable a config.
• The configs in lua/lspconfig/ are deprecated and will be removed.
  • Upgrade to Nvim 0.11+ and use vim.lsp.enable('…') (not require'…'.pyright.setup{}) to enable a config.
• Ask questions on GitHub Discussions, not the issue tracker.
• If you found a bug in Nvim LSP (:help lsp), report it to Neovim core.
  • Do not report it here. Only configuration data lives here.
• This repo only provides configurations. Its programmatic API is deprecated and must not be used externally.
  • The "framework" parts (not the configs) of nvim-lspconfig will be upstreamed to Nvim core.

Install

• Requires Nvim 0.11+. Support for Nvim 0.10 will be removed. Update Nvim and nvim-lspconfig before reporting an issue.
• Install nvim-lspconfig using Vim's "packages" feature:

  git clone https://github.com/neovim/nvim-lspconfig ~/.config/nvim/pack/nvim/start/nvim-lspconfig
  

• Or if you have Nvim 0.12 (in development), you can use the builtin plugin manager:

  vim.pack.add{
    { src = 'https://github.com/neovim/nvim-lspconfig' },
  }
  

• Or use a 3rd-party plugin manager (consult the documentation for your plugin manager).

Quickstart

1. Install a language server, e.g. pyright

   npm i -g pyright
   

2. Add the language server setup to your init.lua.
   • Nvim 0.11+ (see vim.lsp.config)

     vim.lsp.enable('pyright')
     

   • Nvim 0.10 (legacy, not supported)

     require'lspconfig'.pyright.setup{}
     

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.

   nvim main.py
   

5. Run :checkhealth lsp to see the status or to troubleshoot.

Read :help lspconfig for details. Read :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, see vim.lsp.config.

Configuration

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

• :help lsp-defaults
• :help diagnostic-defaults

To customize, see:

• :help lsp-attach
• :h lsp-buf

Extra settings can be specified for each LSP server:

• Nvim 0.11+: You can extend a config as follows (see vim.lsp.config; you can also copy any config directly from lsp/ and put it in a local lsp/ directory in your 'runtimepath').

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

• Nvim 0.10 (legacy, not supported)

  local lspconfig = require('lspconfig')
  lspconfig.rust_analyzer.setup {
    -- Server-specific settings. See `:help lspconfig-setup`
    settings = {
      ['rust-analyzer'] = {},
    },
  }
  

Troubleshooting

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 each server's Lua module from the command line and see that the language server starts. If the cmd is an executable name instead of an absolute path to the executable, ensure it is on your path.
2. Missing filetype plugins. Certain languages are not detected by Vim/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 doc/configs.md.

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 :LspInfo. Add the following to your init.vim to enable logging:

vim.lsp.set_log_level("debug")

Attempt to run the language server, and open the log with:

:LspLog

Most of the time, the reason for failure is present in the logs.

Commands

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

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.
   • Copy an existing config to get started. Most configs are simple. For an extensive example see texlab.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.
