## Requirements
- [Neovim](https://neovim.io/) 0.6 or later
- Lint task requires [luacheck](https://github.com/luarocks/luacheck#installation) and [stylua](https://github.com/JohnnyMorganz/StyLua). If using nix, you can use `nix develop` to install these to a local nix shell.
- Documentation is generated by `scripts/docgen.lua`.
- Only works on linux and macOS
## Scope of lspconfig
The point of lspconfig is to provide the minimal configuration necessary for a server to act in compliance with the language server protocol. In general, if a server requires custom client-side commands or off-spec handlers, then the server configuration should be added *without* those in lspconfig and receive a dedicated plugin such as nvim-jdtls, nvim-metals, etc.
## Pull requests (PRs)
- To avoid duplicate work, create a draft pull request.
- Avoid cosmetic changes to unrelated files in the same commit.
- Use a [feature branch](https://www.atlassian.com/git/tutorials/comparing-workflows) instead of the master branch.
- Use a **rebase workflow** for small PRs.
- After addressing review comments, it's fine to rebase and force-push.
## Adding a server to lspconfig
The general form of adding a new language server is to start with a minimal skeleton. This includes populated the `config` table with a `default_config` and `docs` table.
When choosing a server name, convert all dashes (`-`) to underscores (`_`) If the name of the server is a unique name (`pyright`, `clangd`) or a commonly used abbreviation (`zls`), prefer this as the server name. If the server instead follows the pattern x-language-server, prefer the convention `x_ls` (`jsonnet_ls`).
`default_config` should include, at minimum the following:
* `cmd`: a list which includes the executable name as the first entry, with arguments constituting subsequent list elements (`--stdio` is common).
Note that Windows has a limitation when it comes to directly invoking a server that's installed by `npm` or `gem`, so it requires additional handling.
```lua
cmd = { 'typescript-language-server', '--stdio' }
```
* `filetypes`: a list for filetypes a
* `root_dir`: a function (or function handle) which returns the root of the project used to determine if lspconfig should launch a new language server, or attach a previously launched server when you open a new buffer matching the filetype of the server. Note, lspconfig does not offer a dedicated single file mode (this is not codified in the spec). Do not add `vim.fn.cwd` or `util.path.dirname` in `root_dir`. A future version of lspconfig will provide emulation of a single file mode until this is formally codified in the specification. A good fallback is `util.find_git_ancestor`, see other configurations for examples.
Additionally, the following options are often added:
* `init_options`: a table sent during initialization, corresponding to initializationOptions sent in [initializeParams](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initializeParams) as part of the first request sent from client to server during startup.
* `settings`: a table sent during [`workspace/didChangeConfiguration`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#didChangeConfigurationParams) shortly after server initialization. This is an undocumented convention for most language servers. There is often some duplication with initOptions.
An example for adding a new language server is shown below for `pyright`, a python language server included in lspconfig:
```lua
local util = require 'lspconfig.util'
local root_files = {
'pyproject.toml',
'setup.py',
'setup.cfg',
'requirements.txt',
'Pipfile',
'pyrightconfig.json',
}
local function organize_imports()
local params = {
command = 'pyright.organizeimports',
arguments = { vim.uri_from_bufnr(0) },
}
vim.lsp.buf.execute_command(params)
end
return {
default_config = {
cmd = { 'pyright-langserver', '--stdio' },
filetypes = { 'python' },
root_dir = util.root_pattern(unpack(root_files)),
single_file_support = true,
settings = {
python = {
analysis = {
autoSearchPaths = true,
useLibraryCodeForTypes = true,
diagnosticMode = 'workspace',
},
},
},
},
commands = {
PyrightOrganizeImports = {
organize_imports,
description = 'Organize Imports',
},
},
docs = {
description = [[
https://github.com/microsoft/pyright
`pyright`, a static type checker and language server for python
]],
},
}
```
## Commit style
lspconfig, like neovim core, follows the [conventional commit style](https://www.conventionalcommits.org/en/v1.0.0-beta.2/) please submit your commits accordingly. Generally commits will be of the form:
```
feat: add lua-language-server support
fix(lua-language-server): update root directory pattern
docs: update README.md
```
with the commit body containing additional details.
## Lint
PRs are checked with [luacheck](https://github.com/mpeterv/luacheck), [StyLua](https://github.com/JohnnyMorganz/StyLua) and [selene](https://github.com/Kampfkarren/selene). Please run the linter locally before submitting a PR:
make lint
## Generating docs
GitHub Actions automatically generates `server_configurations.md`. Only modify `scripts/README_template.md` or the `docs` table in the server config Lua file. Do not modify `server_configurations.md` directly.
To preview the generated `server_configurations.md` locally, run `scripts/docgen.lua` from
`nvim` (from the project root):
nvim -R -Es +'set rtp+=$PWD' +'luafile scripts/docgen.lua'

# nvim-lspconfig
[Configs](doc/server_configurations.md) for the [Nvim LSP client](https://neovim.io/doc/user/lsp.html) (`:help lsp`).
* **Do not file Nvim LSP client issues here.** The Nvim LSP client does not live here. This is only a collection of LSP configs.
* If you found a bug in the Nvim LSP client, [report it at the Nvim core repo](https://github.com/neovim/neovim/issues/new?assignees=&labels=bug%2Clsp&template=lsp_bug_report.yml).
* These configs are **best-effort and unsupported.** See [contributions](#contributions).
See also `:help lspconfig`.
## Install
[![LuaRocks](https://img.shields.io/luarocks/v/neovim/nvim-lspconfig?logo=lua&color=purple)](https://luarocks.org/modules/neovim/nvim-lspconfig)
* Requires neovim version 0.8 above. Update Nvim and nvim-lspconfig before reporting an issue.
* Install nvim-lspconfig as a normal plugin through neovim builtin `packadd` or a plugin manager
## Quickstart
1. Install a language server, e.g. [pyright](doc/server_configurations.md#pyright)
```bash
npm i -g pyright
```
2. Add the language server setup to your init.lua.
```lua
require'lspconfig'.pyright.setup{}
```
3. Launch Nvim, the language server will attach and provide diagnostics.
```
nvim main.py
```
4. Run `:LspInfo` to see the status or to troubleshoot.
5. See [Suggested configuration](#Suggested-configuration) to setup common mappings and omnifunc completion.
See [server_configurations.md](doc/server_configurations.md) (`:help lspconfig-all` from Nvim) for the full list of configs, including installation instructions and additional, optional, customization suggestions for each language server. For servers that are not on your system path (e.g., `jdtls`, `elixirls`), you must manually add `cmd` to the `setup` parameter. Most language servers can be installed in less than a minute.
## Suggested configuration
nvim-lspconfig does not set keybindings or enable completion by default. The following example configuration provides suggested keymaps for the most commonly used language server functions, and manually triggered completion with omnifunc (\<c-x\>\<c-o\>).
```lua
-- Setup language servers.
local lspconfig = require('lspconfig')
lspconfig.pyright.setup {}
lspconfig.tsserver.setup {}
lspconfig.rust_analyzer.setup {
-- Server-specific settings. See `:help lspconfig-setup`
settings = {
['rust-analyzer'] = {},
},
}
-- Global mappings.
-- See `:help vim.diagnostic.*` for documentation on any of the below functions
vim.keymap.set('n', '<space>e', vim.diagnostic.open_float)
vim.keymap.set('n', '[d', vim.diagnostic.goto_prev)
vim.keymap.set('n', ']d', vim.diagnostic.goto_next)
vim.keymap.set('n', '<space>q', vim.diagnostic.setloclist)
-- Use LspAttach autocommand to only map the following keys
-- after the language server attaches to the current buffer
vim.api.nvim_create_autocmd('LspAttach', {
group = vim.api.nvim_create_augroup('UserLspConfig', {}),
callback = function(ev)
-- Enable completion triggered by <c-x><c-o>
vim.bo[ev.buf].omnifunc = 'v:lua.vim.lsp.omnifunc'
-- Buffer local mappings.
-- See `:help vim.lsp.*` for documentation on any of the below functions
local opts = { buffer = ev.buf }
vim.keymap.set('n', 'gD', vim.lsp.buf.declaration, opts)
vim.keymap.set('n', 'gd', vim.lsp.buf.definition, opts)
vim.keymap.set('n', 'K', vim.lsp.buf.hover, opts)
vim.keymap.set('n', 'gi', vim.lsp.buf.implementation, opts)
vim.keymap.set('n', '<C-k>', vim.lsp.buf.signature_help, opts)
vim.keymap.set('n', '<space>wa', vim.lsp.buf.add_workspace_folder, opts)
vim.keymap.set('n', '<space>wr', vim.lsp.buf.remove_workspace_folder, opts)
vim.keymap.set('n', '<space>wl', function()
print(vim.inspect(vim.lsp.buf.list_workspace_folders()))
end, opts)
vim.keymap.set('n', '<space>D', vim.lsp.buf.type_definition, opts)
vim.keymap.set('n', '<space>rn', vim.lsp.buf.rename, opts)
vim.keymap.set({ 'n', 'v' }, '<space>ca', vim.lsp.buf.code_action, opts)
vim.keymap.set('n', 'gr', vim.lsp.buf.references, opts)
vim.keymap.set('n', '<space>f', function()
vim.lsp.buf.format { async = true }
end, opts)
end,
})
```
Manual, triggered completion is provided by Nvim's builtin omnifunc. For *auto*completion, a general purpose [autocompletion plugin](https://github.com/neovim/nvim-lspconfig/wiki/Autocompletion) is required.
## Troubleshooting
If you have an issue, the first step is to reproduce with a [minimal configuration](https://github.com/neovim/nvim-lspconfig/blob/master/test/minimal_init.lua).
The most common reasons a language server does not start or attach are:
1. The 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 detecting by vim/neovim because they have not yet been added to the filetype detection system. Ensure `:set ft?` shows the filetype and not an empty value.
3. Not triggering root detection. **Some** language servers will only start if it is opened in a directory, or child directory, containing a file which signals the *root* of the project. Most of the time, this is a `.git` folder, but each server defines the root config in the lua file. See [server_configurations.md](doc/server_configurations.md) or the source for the list of root directories.
4. You must pass `on_attach` and `capabilities` for **each** `setup {}` if you want these to take effect.
5. **Do not call `setup {}` twice for the same server**. The second call to `setup {}` will overwrite the first.
Before reporting a bug, check your logs and the output of `:LspInfo`. Add the following to your init.vim to enable logging:
```lua
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` 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. Pass `autostart = false` to your `.setup{}` call for a language server if you would like to launch clients solely with this command. Defaults to all servers matching current buffer filetype.
* `:LspStop <client_id>` Defaults to stopping all buffer clients.
* `:LspRestart <client_id>` Defaults to restarting all buffer clients.

*lspconfig.txt* For Nvim version 0.8+
nvim-lspconfig provides user-contributed configs for the Nvim |lsp| client.
Type |gO| to see the table of contents.
==============================================================================
INTRODUCTION *lspconfig*
nvim-lspconfig is a collection of community-contributed configurations for the
built-in language server client in Nvim core. This plugin provides four
primary functionalities:
- default launch commands, initialization options, and settings for each
server
- a root directory resolver which attempts to detect the root of your project
- an autocommand mapping that either launches a new language server or
attempts to attach a language server to each opened buffer if it falls
under a tracked project
- utility commands such as LspInfo, LspStart, LspStop, and LspRestart for
managing language server instances
nvim-lspconfig is not required to use the builtin Nvim |lsp| client, it is
just a convenience layer.
See |lspconfig-all| for the complete list of language server configurations.
==============================================================================
QUICKSTART *lspconfig-quickstart*
- ensure the server is installed and executable from the command line
- enable the server in your Neovim configuration (Lua example):
>
require'lspconfig'.clangd.setup{}
<
- create a new project, ensure that it contains a root marker which matches the
server requirements specified in |lspconfig-all|.
- open a file within that project, such as `main.c`.
- If you need more information about a server configuration, read the corresponding
entry in |lspconfig-all|.
==============================================================================
THE SETUP METAMETHOD *lspconfig-setup*
`lspconfig` consists of a collection of language server configurations. Each
configuration exposes a `setup {}` metamethod which makes it easy to directly
use the default configuration or selectively override the defaults.
`setup {}` is the primary interface by which users interact with `lspconfig`.
Using the default configuration for a server is simple:
>
require'lspconfig'.clangd.setup{}
<
The available server names are listed in |lspconfig-all| and match the server
name in `config.SERVER_NAME` defined in each configuration's source file.
The purpose of `setup{}` is to wrap the call to Nvim's built-in
`vim.lsp.start_client()` with an autocommand that automatically launch a
language server.
This autocommand calls `start_client()` or `vim.lsp.buf_attach_client()`
depending on whether the current file belongs to a project with a currently
running client. See |lspconfig-root-detection| for more details.
The `setup{}` function takes a table which contains a superset of the keys
listed in `:help vim.lsp.start_client()` with the following unique entries:
- {root_dir}
`function(filename, bufnr)`
Returns either a filepath (string) or nil. The language server will only
start if the function returns a filepath.
If a root directory (string) is returned which is unique from any
previously returned root_dir, a new server will be spawned with that
root directory. See |lspconfig-root-detection| for more details
- {name}
`string`
Defaults to the server's name (`clangd`, `pyright`, etc.).
- {filetypes}
`list[string] | nil`
Set of filetypes for which to attempt to resolve {root_dir}.
May be empty, or server may specify a default value.
- {autostart}
`bool` (default: true)
Controls if the `FileType` autocommand that launches a language server is
created. If `false`, allows for deferring language servers until manually
launched with `:LspStart` (|lspconfig-commands|).
- {single_file_support}
`bool` (default: nil)
Determines if a server is started without a matching root directory.
See |lspconfig-single-file-support|.
- {on_new_config}
`function(new_config, new_root_dir)`
Function executed after a root directory is detected. This is used to
modify the server configuration (including `cmd` itself). Most commonly,
this is used to inject additional arguments into `cmd`.
If overriding `on_new_config`, ensure that you read the
`on_new_config` defined in the source file of the default configuration
in `lspconfig`. The original `on_new_config` snippet for a given server
should likely be included in your new override. Some configurations
use `on_new_config` to dynamically set or modify `cmd`.
Note: all entries passed to `setup {}` override the entry in the default
configuration. There is no composition.
All `config` elements described in `:help vim.lsp.start_client()` can
additionally be overridden via the `setup {}` call. The most commonly
passed overrides to `setup {}` are:
- {capabilities} `table <string, string|table|bool|function>`
a table which represents the neovim client capabilities. Useful for
broadcasting to the server additional functionality (snippets, off-protocol
features) provided by plugins.
- {cmd} `list[string]`
a list where each entry corresponds to the blankspace delimited part of
the command that launches the server. The first entry is the binary used
to run the language server. Additional entries are passed as arguments.
The equivalent `cmd` for:
>
foo --bar baz
<
is:
>
{'foo', '--bar', 'baz'}
<
- {handlers} `list[functions]`
a list of handlers which override the function used to process a response
from a given language server. Applied only to the server referenced by
setup. See |lsp-handler|.
- {init_options} `table <string, string|table|bool>`
a table passed during the initialization notification after launching
a language server. Equivalent to the `initializationOptions` field found
in `InitializeParams` in the LSP specification.
See upstream server documentation for available initialization
options.
- {on_attach} `function(client, bufnr)`
Callback invoked by Nvim's built-in client when attaching a buffer to a
language server. Often used to set Nvim (buffer or global) options or to
override the Nvim client properties (`server_capabilities`) after a
language server attaches. Most commonly used for settings buffer
local keybindings. See |lspconfig-keybindings| for a usage example.
- {settings} `table <string, string|table|bool>`
The `settings` table is sent in `on_init` via a
`workspace/didChangeConfiguration` notification from the Nvim client to
the language server. These settings allow a user to change optional runtime
settings of the language server.
As an example, to set the following settings found in the pyright
documentation:
`pyright.disableLanguageServices`: `boolean`
`pyright.disableOrganizeImports`: `boolean`
Nested keys need to be translated into a nested table and passed to
the settings field in `setup {}` as follows:
>
require('lspconfig').pyright.setup{
settings = {
pyright = {
disableLanguageServices = true,
disableOrganizeImports = true,
}
}
}
<
==============================================================================
OVERRIDING GLOBAL DEFAULTS *lspconfig-global-defaults*
The global defaults for all servers can be overridden by extending the
`default_config` table.
>
local lspconfig = require'lspconfig'
lspconfig.util.default_config = vim.tbl_extend(
"force",
lspconfig.util.default_config,
{
autostart = false,
handlers = {
["window/logMessage"] = function(err, method, params, client_id)
if params and params.type <= vim.lsp.protocol.MessageType.Log then
vim.lsp.handlers["window/logMessage"](err, method, params, client_id)
end
end,
["window/showMessage"] = function(err, method, params, client_id)
if params and params.type <= vim.lsp.protocol.MessageType.Warning.Error then
vim.lsp.handlers["window/showMessage"](err, method, params, client_id)
end
end,
}
}
)
<
`setup {}` can additionally override these defaults in subsequent calls.
==============================================================================
SETUP HOOK *lspconfig-setup-hook*
`lspconfig` will execute the `on_setup` hook for each setup call to a server after
validating its configuration, and before attempting to launch the server
itself. One typical usage is to allow ad-hoc substitution for any
configuration entry, such as `cmd`.
>
local lspconfig = require 'lspconfig'
lspconfig.util.on_setup = lspconfig.util.add_hook_before(lspconfig.util.on_setup, function(config)
if some_condition and config.name == "clangd" then
local custom_server_prefix = "/my/custom/server/prefix"
config.cmd = { custom_server_prefix .. "/bin/clangd" }
end
end)
Note: This is primarily targeted at plugins developers, so make sure to use
`util.add_hook_before()` as a wrapper instead of overriding the original function
completely, to void breaking external integrations with lspconfig.
==============================================================================
SERVER CONFIGURATIONS *lspconfig-configurations*
See |lspconfig-all| for the complete list of language server configurations.
While the `setup {}` function is the primary interface to `lspconfig`, for
servers for which there is not a configuration, it is necessary to define a
configuration directly. This can be useful if there is an outstanding PR that
is in review, or when developing a language server that is unavailable
publicly. This can be done through the `configs` module.
The `configs` module is a singleton where configs are defined. The schema for
validating using `vim.validate` is:
>
configs.SERVER_NAME = {
default_config = {'t'},
on_new_config = {'f', true},
on_attach = {'f', true},
commands = {'t', true},
docs = {'t', true},
}
<
where the structure of the docs table is as follows:
>
docs = {
description = {'s', true},
default_config = {'t', true},
}
<
`commands` is a map of `name:definition` key:value pairs, where `definition`
is a list whose first value is a function implementing the command, and the
rest are either array values which will be formed into flags for the command,
or special keys like `description`.
Warning: Commands is deprecated and will be removed in future releases.
It is recommended to use `vim.api.nvim_create_user_command()` instead in an `on_attach` function.
Example:
>
local function organize_imports()
local params = {
command = 'pyright.organizeimports',
arguments = { vim.uri_from_bufnr(0) },
}
vim.lsp.buf.execute_command(params)
end
local on_attach = function(client, bufnr)
if client.name == "pyright" then
vim.api.nvim_create_user_command("PyrightOrganizeImports", organize_imports, {desc = 'Organize Imports'})
end
end
require("lspconfig")['pyright'].setup({
on_attach = on_attach
})
<
The `configs.__newindex` metamethod consumes the config definition and returns
an object with a `setup()` method, to be invoked by users:
>
require'lspconfig'.SERVER_NAME.setup{}
After you set `configs.SERVER_NAME` you can add arbitrary language-specific
functions to it if necessary.
Example:
>
configs.texlab.buf_build = buf_build
<
==============================================================================
ADDING NEW SERVERS *lspconfig-new*
The steps for adding and enabling a new server configuration are:
1. load the `lspconfig` module (note that this is a stylistic choice) >
local lspconfig = require 'lspconfig'
<
2. define the configuration >
local configs = require 'lspconfig.configs'
-- Check if the config is already defined (useful when reloading this file)
if not configs.foo_lsp then
configs.foo_lsp = {
default_config = {
cmd = {'/home/neovim/lua-language-server/run.sh'},
filetypes = {'lua'},
root_dir = function(fname)
return lspconfig.util.find_git_ancestor(fname)
end,
settings = {},
},
}
end
3. call `setup()` to enable the FileType autocmd >
lspconfig.foo_lsp.setup{}
<
==============================================================================
ROOT DETECTION *lspconfig-root-detection*
*lspconfig-root-dir*
A project's `root_dir` is used by `lspconfig` to determine whether `lspconfig`
should start a new server, or attach a previous one, to the current file.
`lspconfig` automatically launches language servers by defining a filetype
autocommand based on the `filetypes` specified in the default configuration of
each server, optionally overridable by the `filetypes` table passed to
`setup`.
This autocommand triggers a search from the current file position in the
filesystem hierarchy up to the top level directory of your filesystem. The
`root_dir` entry of each configuration is a function that returns true if the
current directory in this traversal matches a given root pattern.
The following utility functions are provided by `lspconfig`. Each function call
below returns a function that takes as its argument the current buffer path.
- `util.root_pattern`: function which takes multiple arguments, each
corresponding to a different root pattern against which the contents of the
current directory are matched using |vim.fn.glob()| while traversing up the
filesystem. Parent directories are traversed once per pattern, in the order
the patterns are specified.
>
root_dir = util.root_pattern('pyproject.toml', 'requirements.txt')
<
- `util.find_git_ancestor`: a function that locates the first parent directory
containing a `.git` directory.
>
root_dir = util.find_git_ancestor
- `util.find_node_modules_ancestor`: a function that locates the first parent
directory containing a `node_modules` directory.
>
root_dir = util.find_node_modules_ancestor
<
- `util.find_package_json_ancestor`: a function that locates the first parent
directory containing a `package.json`.
>
root_dir = util.find_json_ancestor
<
Note: On Windows, `lspconfig` always assumes forward slash normalized paths with
capitalized drive letters.
==============================================================================
ADVANCED ROOT DIRECTORY DETECTION *lspconfig-root-advanced*
*lspconfig-root-composition*
The `root_dir` key in `config` and `setup` can hold any function of the form
>
function custom_root_dir(filename, bufnr)
returns nil | string
>
This allows for rich composition of root directory patterns which is necessary
for some project structures. Example (for Kotlin):
>
local root_files = {
'settings.gradle', -- Gradle (multi-project)
'settings.gradle.kts', -- Gradle (multi-project)
'build.xml', -- Ant
'pom.xml', -- Maven
}
local fallback_root_files = {
'build.gradle', -- Gradle
'build.gradle.kts', -- Gradle
}
root_dir = function(fname)
local primary = util.root_pattern(unpack(root_files))(fname)
local fallback = util.root_pattern(unpack(fallback_root_files))(fname)
return primary or fallback
end
<
Browsing the source of the default configurations is recommended.
==============================================================================
SINGLE FILE SUPPORT *lspconfig-single-file-support*
Language servers require each project to have a `root` in order to provide
features that require cross-file indexing.
Some servers support not passing a root directory as a proxy for single file
mode under which cross-file features may be degraded.
`lspconfig` offers limited support for an implicit single-file mode by:
- first trying to resolve the root directory pattern
- then, if `single_file_support` is enabled for a given language server
configuration, starting the server without sending `rootDirectory` or
`workspaceFolders` during initialization.
- attaching subsequent files in the parent directory to the same server
instance, depending on filetype.
- also supports unnamed buffer if filetype matches the server filetype
settings.
Cross-file features (navigation, hover) may or may not work depending on the
language server. For a full feature-set, consider moving your files to a
directory with a project structure `lspconfig` can infer.
Note that in the event that the LSP specification is extended to support a
standard for single-file mode, lspconfig will adopt that standard.
==============================================================================
COMMANDS *lspconfig-commands*
- `:LspInfo` shows the status of active and configured language servers. Note
that client id refers to the Nvim RPC instance connected to a given
language server.
The following commands support tab-completion for all arguments. All commands
that require a client id can either leverage tab-completion or the info
contained in `:LspInfo`:
- `:LspStart <config_name>` launches the requested (configured) client, but only
if it successfully resolves a root directory. Note: Defaults to all
configured servers matching the current buffer filetype.
- `:LspStop <client_id>` stops the server with the given client id. Defaults to
stopping all servers active on the current buffer. if you want to force stop
a language server you can do it like `:LspStop <client_id> ++force`
- `:LspRestart <client_id>` restarts the client with the given client id, and
will attempt to reattach to all previously attached buffers.
==============================================================================
EXAMPLE KEYBINDINGS *lspconfig-keybindings*
`lspconfig`, and the core client, do not map any keybindings by default. The
following is an example Lua block which demonstrates how to leverage
`LspAttach` (Nvim 0.8+) autocommand to apply keybindings after a language
servers has attached to a given buffer.
>
-- Setup language servers.

end,
})
==============================================================================
COMPLETION SUPPORT *lspconfig-completion*
Manually triggered completion can be provided by Nvim's built-in omnifunc.
See |lspconfig|.
For autocompletion, Nvim does not provide built-in functionality. Consult the
nvim-lspconfig wiki, which provides configuration examples for using
a completion plugin with the built-in client
==============================================================================
DEBUGGING *lspconfig-debugging*
While using language servers should be easy, debugging issues can be
challenging. First, it is important to identify the source of the issue, which
is typically (in rough order):
- the language server itself
- a plugin
- overrides in a user configuration
- the built-in client in Nvim core
- nvim-lspconfig
The first step in debugging is to test with a minimal configuration (such as
`../test/minimal_init.lua`). Historically, many users problems are due to
plugins or misconfiguration.
Should that fail, identifying which component is the culprit is challenging.
The following are the only categories of bugs that pertain to nvim-lspconfig.
- The root directory inferred for your project is wrong, or it should be
detected but is not due to a bug in the nvim-lspconfig path utilities.
- The server is launching, but you believe that the default settings,
initialization options, or command arguments are suboptimal and should be
replaced based on your understanding of the server documentation.
All bugs Nvim's built-in client should be reported to the Nvim core issue
tracker. All bugs pertaining to plugins should be reported to the respective
plugin. All missing features in a language server should be reported to the
upstream language server issue tracker.
For debugging nvim-lspconfig issues, the most common hurdles users face are:
- The language server is not installed or is otherwise not executable.
nvim-lspconfig does not install language servers for you. Ensure the `cmd`
defined in `server_configurations.md` is executable from the command
line. If the absolute path to the binary is not supplied in `cmd`, ensure
it is on your PATH.
- No root detected. nvim-lspconfig is built around the concept of projects. See
|lspconfig-root-detection| for more details. Most of the time,
initializing a git repo will suffice.
- Misconfiguration. Often users will override `cmd`, `on_init`, or
`handlers`. Ensure that you debug by using a stock configuration to ensure
your customizations are not introducing issues.
|LspInfo| provides an overview of your active and configured language servers
which can be useful for debugging.
Note that it will not report any configuration changes applied in
`on_new_config`.
==============================================================================
LOGGING *lspconfig-logging*
When debugging language servers, it is helpful to enable additional logging in
the built-in client, specifically considering the RPC logs. Example:
>
vim.lsp.set_log_level 'trace'
if vim.fn.has 'nvim-0.5.1' == 1 then
require('vim.lsp.log').set_format_func(vim.inspect)
end
<
Attempt to run the language server, and open the log with:
>
:LspLog
<
Note that `ERROR` messages containing `stderr` only indicate that the log was
sent to `stderr`. Many servers counter-intuitively send harmless messages
via stderr.
==============================================================================
SCOPE *lspconfig-scope*
`lspconfig` is a community effort to create default configurations that fit
within the scope of an official plugin for Nvim. All features that are not
strictly providing default configurations for language servers will be removed
from `lspconfig` in time. The power of the Neovim LSP ecosystem is in the
composability and flexibility of integrating multiple plugins which maximizes
user choice and freedom.
`lspconfig` also opts to adhere strictly to the LSP specification, with some
small allowances when small modifications to a server configuration are
necessary to enable features critical to its usability. For more featureful
options, the `lspconfig` wiki lists community created plugins that build upon
the built-in client to provide functionality tailored to specific language
servers.
==============================================================================
Highlights *lspconfig-highlight*
LspInfoTitle Client name
LspInfoList Server name list
LspInfoFiletype `filetypes` area
LspInfoTip Tip
LspInfoBorder Window border
To set the border use: >
require('lspconfig.ui.windows').default_options.border = 'single'
< Accepts the same values as the `border` option to |nvim_open_win()|

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](https://arduino.github.io/arduino-cli/latest/installation/) for
your platform.
After installing `arduino-cli`, follow [these
instructions](https://arduino.github.io/arduino-cli/latest/getting-started/#create-a-configuration-file)
for generating a configuration file if you haven't done so already, 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` to be installed. Follow [these
installation instructions](https://clangd.llvm.org/installation) 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 like 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 like like this:
```yaml
default_fqbn: arduino:avr:uno
default_port: /dev/ttyACM0
```
Your folder structure should look like this:
```
.
test.ino
sketch.yaml
```
For further instruction about configuration options, run `arduino-language-server --help`.
Note that an upstream bug makes keywords in some cases become undefined by the language server.

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 \

Language server for the [Drools Rule Language (DRL)](https://docs.drools.org/latest/drools-docs/docs-website/drools/language-reference/#con-drl_drl-rules).
The `drools-lsp` server is a self-contained java jar file (`drools-lsp-server-jar-with-dependencies.jar`), and can be downloaded from [https://github.com/kiegroup/drools-lsp/releases/](https://github.com/kiegroup/drools-lsp/releases/).
Configuration information:
```lua
-- Option 1) Specify the entire command:
require('lspconfig').drools_lsp.setup {
cmd = { '/path/to/java', '-jar', '/path/to/drools-lsp-server-jar-with-dependencies.jar' },
}
-- Option 2) Specify just the jar path (the JAVA_HOME environment variable will be respected if present):
require('lspconfig').drools_lsp.setup {
drools = { jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar' },
}
-- Option 3) Specify the java bin and/or java opts in addition to the jar path:
require('lspconfig').drools_lsp.setup {
drools = {
java = { bin = '/path/to/java', opts = { '-Xmx100m' } },
jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar',
},
}
```
Neovim does not yet have automatic detection for the `drools` filetype, but it can be added with:
```lua
vim.cmd [[ autocmd BufNewFile,BufRead *.drl set filetype=drools ]]
```

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

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.
