LSP client/framework                                     *lsp* *LSP*

Nvim supports the Language Server Protocol (LSP), which means it acts as
a client to LSP servers and includes a Lua framework `vim.lsp` for building
enhanced LSP tools.

  https://microsoft.github.io/language-server-protocol/

LSP facilitates features like go-to-definition, find-references, hover,
completion, rename, format, refactor, etc., using semantic whole-project
analysis (unlike |ctags|).

                                      Type |gO| to see the table of contents.

QUICKSTART                                              *lsp-quickstart*

Nvim provides an LSP client, but the servers are provided by third parties.
Follow these steps to get LSP features:

  1. Install the nvim-lspconfig plugin.  It provides common configuration for
     various servers so you can get started quickly.
     https://github.com/neovim/nvim-lspconfig
  2. Install a language server. A list of language servers can be found here:
     https://microsoft.github.io/language-server-protocol/implementors/servers/
     See individual server documentation for installation instructions.
  3. Add `lua require('lspconfig').xx.setup{…}` to your init.vim, where "xx" is
     the name of the relevant config. See the nvim-lspconfig README for details.
     NOTE: Make sure to restart nvim after installing and configuring.
  4. Check that an LSP client has attached to the current buffer:  >

      :lua print(vim.inspect(vim.lsp.buf_get_clients()))
<
                                                        *lsp-config*
Inline diagnostics are enabled automatically, e.g. syntax errors will be
annotated in the buffer.  But you probably also want to use other features
like go-to-definition, hover, etc.

While Nvim does not provide an "auto-completion" framework by default, it is
still possible to get completions from the LSP server. To incorporate these
completions, it is recommended to use |vim.lsp.omnifunc|, which is an 'omnifunc'
handler. When 'omnifunc' is set to `v:lua.vim.lsp.omnifunc`, |i_CTRL-X_CTRL-O|
will provide completions from the language server.

Example config (in init.vim): >

  lua << EOF
    local custom_lsp_attach = function(client)
      -- See `:help nvim_buf_set_keymap()` for more information
      vim.api.nvim_buf_set_keymap(0, 'n', 'K', '<cmd>lua vim.lsp.buf.hover()<CR>', {noremap = true})
      vim.api.nvim_buf_set_keymap(0, 'n', '<c-]>', '<cmd>lua vim.lsp.buf.definition()<CR>', {noremap = true})
      -- ... and other keymappings for LSP

      -- Use LSP as the handler for omnifunc.
      --    See `:help omnifunc` and `:help ins-completion` for more information.
      vim.api.nvim_buf_set_option(0, 'omnifunc', 'v:lua.vim.lsp.omnifunc')

      -- For plugins with an `on_attach` callback, call them here. For example:
      -- require('completion').on_attach()
    end

    -- An example of configuring for `sumneko_lua`,
    --  a language server for Lua.

    -- set the path to the sumneko installation
    local system_name = "Linux" -- (Linux, macOS, or Windows)
    local sumneko_root_path = '/path/to/lua-language-server'
    local sumneko_binary = sumneko_root_path.."/bin/"..system_name.."/lua-language-server"

    require('lspconfig').sumneko_lua.setup({
      cmd = {sumneko_binary, "-E", sumneko_root_path .. "/main.lua"};
      -- An example of settings for an LSP server.
      --    For more options, see nvim-lspconfig
      settings = {
        Lua = {
          runtime = {
            -- Tell the language server which version of Lua you're using (most likely LuaJIT in the case of Neovim)
            version = 'LuaJIT',
            -- Setup your lua path
            path = vim.split(package.path, ';'),
          },
          diagnostics = {
            -- Get the language server to recognize the `vim` global
            globals = {'vim'},
          },
          workspace = {
            -- Make the server aware of Neovim runtime files
            library = {
              [vim.fn.expand('$VIMRUNTIME/lua')] = true,
              [vim.fn.expand('$VIMRUNTIME/lua/vim/lsp')] = true,
            },
          },
        }
      },

      on_attach = custom_lsp_attach
    })

FAQ                                                     *lsp-faq*

- Q: How to force-reload LSP?
  A: Stop all clients, then reload the buffer. >

     :lua vim.lsp.stop_client(vim.lsp.get_active_clients())
     :edit

- Q: Why isn't completion working?
  A: In the buffer where you want to use LSP, check that 'omnifunc' is set to
     "v:lua.vim.lsp.omnifunc": >

     :verbose set omnifunc?

<     Some other plugin may be overriding the option. To avoid that, you could
     set the option in an |after-directory| ftplugin, e.g.
     "after/ftplugin/python.vim".

- Q: How do I run a request synchronously (e.g. for formatting on file save)?
  A: Use the `_sync` variant of the function provided by |lsp-buf|, if it
     exists.

     E.g. code formatting: >

     " Auto-format *.rs (rust) files prior to saving them
     autocmd BufWritePre *.rs lua vim.lsp.buf.formatting_sync(nil, 1000)

<
                                                           *lsp-vs-treesitter*
- Q: How do LSP and Treesitter compare?
  A: LSP requires a client and language server. The language server uses
     semantic analysis to understand code at a project level. This provides
     language servers with the ability to rename across files, find
     definitions in external libraries and more.

     Treesitter is a language parsing library that provides excellent tools
     for incrementally parsing text and handling errors. This makes it a great
     fit for editors to understand the contents of the current file for things
     like syntax highlighting, simple goto-definitions, scope analysis and
     more.

     LSP and Treesitter are both great tools for editing and inspecting code.

LSP API                                                 *lsp-api*

LSP core API is described at |lsp-core|.  Those are the core functions for
creating and managing clients.

The `vim.lsp.buf_…` functions perform operations for all LSP clients attached
to the given buffer. |lsp-buf|

LSP request/response handlers are implemented as Lua functions (see
|lsp-handler|). The |vim.lsp.handlers| table defines default handlers used
when creating a new client. Keys are LSP method names: >

  :lua print(vim.inspect(vim.tbl_keys(vim.lsp.handlers)))
<
                                                                  *lsp-method*

Methods are the names of requests and notifications as defined by the LSP
specification. These LSP requests/notifications are defined by default:

    callHierarchy/incomingCalls
    callHierarchy/outgoingCalls
    textDocument/codeAction
    textDocument/completion
    textDocument/declaration*
    textDocument/definition
    textDocument/documentHighlight
    textDocument/documentSymbol
    textDocument/formatting
    textDocument/hover
    textDocument/implementation*
    textDocument/publishDiagnostics
    textDocument/rangeFormatting
    textDocument/references
    textDocument/rename
    textDocument/signatureHelp
    textDocument/typeDefinition*
    window/logMessage
    window/showMessage
    window/showMessageRequest
    workspace/applyEdit
    workspace/symbol

* NOTE: These are sometimes not implemented by servers.

                                                                 *lsp-handler*

lsp-handlers are functions with special signatures that are designed to handle
responses and notifications from LSP servers.

For |lsp-request|, each |lsp-handler| has this signature: >

  function(err, method, result, client_id, bufnr, config)
<
        Parameters: ~
            {err}       (table|nil)
                            When the language server is unable to complete a
                            request, a table with information about the error
                            is sent. Otherwise, it is `nil`. See |lsp-response|.
            {method}    (string)
                            The |lsp-method| name.
            {result}    (Result | Params | nil)
                            When the language server is able to succesfully
                            complete a request, this contains the `result` key
                            of the response. See |lsp-response|.
            {client_id} (number)
                            The ID of the |vim.lsp.client|.
            {bufnr}     (Buffer)
                            Buffer handle, or 0 for current.
            {config}    (table)
                            Configuration for the handler.

                            Each handler can define it's own configuration
                            table that allows users to customize the behavior
                            of a particular handler.

                            To configure a particular |lsp-handler|, see:
                                |lsp-handler-configuration|

        Returns: ~
            The |lsp-handler| can respond by returning two values: `result, err`
              Where `err` must be shaped like an RPC error:
                `{ code, message, data? }`

            You can use |vim.lsp.rpc_response_error()| to create this object.

For |lsp-notification|, each |lsp-handler| has this signature: >

  function(err, method, params, client_id, bufnr, config)
<
        Parameters: ~
            {err}       (nil)
                            This is always `nil`.
                            See |lsp-notification|
            {method}    (string)
                            The |lsp-method| name.
            {params}    (Params)
                            This contains the `params` key of the notification.
                            See |lsp-notification|
            {client_id} (number)
                            The ID of the |vim.lsp.client|
            {bufnr}     (nil)
                            `nil`, as the server doesn't have an associated buffer.
            {config}    (table)
                            Configuration for the handler.

                            Each handler can define it's own configuration
                            table that allows users to customize the behavior
                            of a particular handler.

                            For an example, see:
                                |vim.lsp.diagnostic.on_publish_diagnostics()|

                            To configure a particular |lsp-handler|, see:
                                |lsp-handler-configuration|

        Returns: ~
            The |lsp-handler|'s return value will be ignored.

                                                   *lsp-handler-configuration*

To configure the behavior of a builtin |lsp-handler|, the convenient method
|vim.lsp.with()| is provided for users.

  To configure the behavior of |vim.lsp.diagnostic.on_publish_diagnostics()|,
  consider the following example, where a new |lsp-handler| is created using
  |vim.lsp.with()| that no longer generates signs for the diagnostics: >

  vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(
    vim.lsp.diagnostic.on_publish_diagnostics, {
      -- Disable signs
      signs = false,
    }
  )
<
  To enable signs, use |vim.lsp.with()| again to create and assign a new
  |lsp-handler| to |vim.lsp.handlers| for the associated method: >

   vim.lsp.handlers["textDocument/publishDiagnostics"] = vim.lsp.with(
     vim.lsp.diagnostic.on_publish_diagnostics, {
       -- Enable signs
       signs = true,
     }
   )
<
  To configure a handler on a per-server basis, you can use the {handlers} key
  for |vim.lsp.start_client()| >

   vim.lsp.start_client {
     ..., -- Other configuration omitted.
     handlers = {
       ["textDocument/publishDiagnostics"] = vim.lsp.with(
         vim.lsp.diagnostic.on_publish_diagnostics, {
           -- Disable virtual_text
           virtual_text = false,
         }
       },
     }
<
  or if using 'nvim-lspconfig', you can use the {handlers} key of `setup()`: >

   require('lspconfig').rust_analyzer.setup {
     handlers = {
       ["textDocument/publishDiagnostics"] = vim.lsp.with(
         vim.lsp.diagnostic.on_publish_diagnostics, {
           -- Disable virtual_text
           virtual_text = false
         }
       ),
     }
   }
<
  Some handlers do not have an explicitly named handler function (such as
  |on_publish_diagnostics()|). To override these, first create a reference
  to the existing handler: >

    local on_references = vim.lsp.handlers["textDocument/references"]
    vim.lsp.handlers["textDocument/references"] = vim.lsp.with(
      on_references, {
        -- Use location list instead of quickfix list
        loclist = true,
      }
    )
<
                                                      *lsp-handler-resolution*
Handlers can be set by:

- Setting a field in |vim.lsp.handlers|.                      *vim.lsp.handlers*
    |vim.lsp.handlers| is a global table that contains the default mapping of
    |lsp-method| names to |lsp-handlers|.

    To override the handler for the `"textDocument/definition"` method: >

  vim.lsp.handlers["textDocument/definition"] = my_custom_default_definition
<
- The {handlers} parameter for |vim.lsp.start_client|.
    This will set the |lsp-handler| as the default handler for this server.

    For example: >

  vim.lsp.start_client {
    ..., -- Other configuration ommitted.
    handlers = {
        ["textDocument/definition"] = my_custom_server_definition
    },
  }

- The {handler} parameter for |vim.lsp.buf_request()|.
    This will set the |lsp-handler| ONLY for the current request.

    For example: >

  vim.lsp.buf_request(
    0,
    "textDocument/definition",
    definition_params,
    my_request_custom_definition
  )
<
In summary, the |lsp-handler| will be chosen based on the current |lsp-method|
in the following order:

1. Handler passed to |vim.lsp.buf_request()|, if any.
2. Handler defined in |vim.lsp.start_client()|, if any.
3. Handler defined in |vim.lsp.handlers|, if any.


VIM.LSP.PROTOCOL                                              *vim.lsp.protocol*

Module `vim.lsp.protocol` defines constants dictated by the LSP specification,
and helper functions for creating protocol-related objects.
https://github.com/microsoft/language-server-protocol/raw/gh-pages/_specifications/specification-3-14.md

For example `vim.lsp.protocol.ErrorCodes` allows reverse lookup by number or
name: >

LSP HIGHLIGHT                                                    *lsp-highlight*

Reference Highlights:

Highlight groups that are meant to be used by |vim.lsp.buf.document_highlight()|.

You can see more about the differences in types here:
https://microsoft.github.io/language-server-protocol/specification#textDocument_documentHighlight

                                                           *hl-LspReferenceText*
LspReferenceText          used for highlighting "text" references

corresponding LspDiagnosticsDefault highlight.

For example, the default highlighting for |hl-LspDiagnosticsSignError| is
linked to |hl-LspDiagnosticsDefaultError|. To change the default (and
therefore the linked highlights), use the |:highlight| command: >

    highlight LspDiagnosticsDefaultError guifg="BrightRed"

                      requests.
                    • Function which can be used to cancel all the requests.
                      You could instead iterate all clients and call their
                      `cancel_request()` methods.

                return result and callback are different.

                Parameters: ~

                Return: ~
                    (function) A function that will cancel all requests which
                    is the same as the one returned from `buf_request` .

                Sends a request to all server and waits for the response of
                all of them.

                Calls |vim.lsp.buf_request_all()| but blocks Nvim while
                awaiting the result. Parameters are the same as
                |vim.lsp.buf_request()| but the return result is different.
                Wait maximum of {timeout_ms} (default 1000) ms.

client()                                                      *vim.lsp.client*
                LSP client object. You can get an active client object via
                |vim.lsp.get_client_by_id()| or
                |vim.lsp.get_active_clients()|.

                • Methods:
                  • request(method, params, [handler], bufnr) Sends a request
                    to the server. This is a thin wrapper around
                    {client.rpc.request} with some additional checking. If
                    {handler} is not specified, If one is not found there,
                    then an error will occur. Returns: {status},
                    {[client_id]}. {status} is a boolean indicating if the
                    notification was successful. If it is `false` , then it
                    will always be `false` (the client has shutdown). If
                    {status} is `true` , the function returns {request_id} as
                    the second result. You can use this with
                    `client.cancel_request(request_id)` to cancel the request.
                  • request_sync(method, params, timeout_ms, bufnr) Sends a
                    request to the server and synchronously waits for the
                    response. This is a wrapper around {client.request}
                    Returns: { err=err, result=result }, a dictionary, where
                    `err` and `result` come from the |lsp-handler|. On
                    timeout, cancel or error, returns `(nil, err)` where `err`
                    is a string describing the failure reason. If the request
                    was unsuccessful returns `nil` .
                  • notify(method, params) Sends a notification to an LSP
                    server. Returns: a boolean to indicate if the notification
                    was successful. If it is false, then it will always be
                    false (the client has shutdown).
                  • cancel_request(id) Cancels a request with a given request
                    id. Returns: same as `notify()` .
                  • stop([force]) Stops a client, optionally with force. By
                    default, it will just ask the server to shutdown without
                    force. If you request to stop a client which has
                    previously been requested to shutdown, it will
                    automatically escalate and force shutdown.
                  • is_stopped() Checks whether a client is stopped. Returns:
                    true if the client is fully stopped.
                  • on_attach(client, bufnr) Runs the on_attach function from
                    the client's config if it was defined. Useful for
                    buffer-local setup.

                • Members
                  • {id} (number): The id allocated to the client.
                  • {name} (string): If a name is specified on creation, that
                    will be used. Otherwise it is just the client id. This is
                    used for logs and messages.
                  • {rpc} (table): RPC client object, for low level
                    interaction with the client. See |vim.lsp.rpc.start()|.
                  • {offset_encoding} (string): The encoding used for
                    communicating with the server. You can modify this in the
                    `config` 's `on_init` method before text is sent to the
                    server.
                  • {handlers} (table): The handlers used by the client as
                    described in |lsp-handler|.
                  • {config} (table): copy of the table that was passed by the
                    user to |vim.lsp.start_client()|.
                  • {server_capabilities} (table): Response from the server
                    sent on `initialize` describing the server's capabilities.
                  • {resolved_capabilities} (table): Normalized table of
                    capabilities that we have detected based on the initialize
                    response from the server in `server_capabilities` .

                                         like |jobstart()|) Base command that
                                         initiates the LSP client.
                    {cmd_cwd}            (string, default=|getcwd()|)
                                         Directory to launch the `cmd`
                                         process. Not related to `root_dir` .
                    {cmd_env}            (table) Environment flags to pass to
                                         the LSP on spawn. Can be specified
                                         using keys like a map or as a list
                                         with `k=v` pairs or both. Non-string values are
                                         coerced to string. Example: >

                    {capabilities}       Map overriding the default
                                         capabilities defined by
                                         |vim.lsp.protocol.make_client_capabilities()|,
                                         passed to the language server on
                                         initialization. Hint: use
                                         make_client_capabilities() and modify
                                         its result.
                                         • Note: To send an empty dictionary
                                           use
                                           `{[vim.type_idx]=vim.types.dictionary}`
                                           , else it will be encoded as an
                                           array.
                    {handlers}           Map of language server method names

                    {settings}           Map with language server specific
                                         settings. These are returned to the
                                         language server if requested via
                                         `workspace/configuration` . Keys are
                                         case-sensitive.
                    {init_options}       Values to pass in the initialization
                                         request as `initializationOptions` .
                                         See `initialize` in the LSP spec.
                    {name}               (string, default=client-id) Name in
                                         log messages.
                    {workspace_folders}  (table) List of workspace folders
                                         passed to the language server.
                                         Defaults to root_dir if not set. See
                                         `workspaceFolders` in the LSP spec
                    {get_language_id}    function(bufnr, filetype) -> language
                                         ID as string. Defaults to the
                                         filetype.
                    {offset_encoding}    (default="utf-16") One of "utf-8",
                                         "utf-16", or "utf-32" which is the
                                         encoding that the LSP server expects.
                                         Client does not verify this is
                                         correct.
                    {on_error}           Callback with parameters (code, ...),
                                         invoked when the client operation
                                         throws an error. `code` is a number
                                         describing the error. Other arguments
                                         may be passed depending on the error
                                         kind. See |vim.lsp.client_errors| for
                                         possible errors. Use
                                         `vim.lsp.client_errors[code]` to get
                                         human-friendly name.
                    {before_init}        Callback with parameters
                                         (initialize_params, config) invoked
                                         before the LSP "initialize" phase,
                                         where `params` contains the
                                         parameters being sent to the server
                                         and `config` is the config that was
                                         passed to |vim.lsp.start_client()|.
                                         You can use this to modify parameters
                                         before they are sent.
                    {on_init}            Callback (client, initialize_result)
                                         invoked after LSP "initialize", where
                                         `result` is a table of `capabilities`
                                         and anything else the server may
                                         send. For example, clangd sends
                                         `initialize_result.offsetEncoding` if
                                         `capabilities.offsetEncoding` was
                                         sent to it. You can only modify the
                                         `client.offset_encoding` here before
                                         any notifications are sent. Most
                                         language servers expect to be sent
                                         client specified settings after
                                         initialization. Neovim does not make
                                         this assumption. A
                                         `workspace/didChangeConfiguration`
                                         notification should be sent to the
                                         server during on_init.
                    {on_exit}            Callback (code, signal, client_id)
                                         invoked on client exit.
                                         • code: exit code of the process
                                         • signal: number describing the
                                           signal used to terminate (if any)
                                         • client_id: client handle
                    {on_attach}          Callback (client, bufnr) invoked when
                                         client attaches to a buffer.
                    {trace}              "off" | "messages" | "verbose" | nil
                                         passed directly to the language
                                         server in the initialize request.
                                         Invalid/empty values will default to

                    {flags}              A table with flags for the client.
                                         The current (experimental) flags are:
                                         • allow_incremental_sync (bool,
                                           default true): Allow using
                                           incremental sync for buffer edits
                                         • debounce_text_changes (number,
                                           default nil): Debounce didChange
                                           notifications to the server by the
                                           given number in milliseconds. No
                                           debounce occurs if nil

                Return: ~
                    Client id. |vim.lsp.get_client_by_id()| Note: client may
                    not be fully initialized. Use `on_init` to do any actions
                    once the client has been initialized.

stop_client({client_id}, {force})                      *vim.lsp.stop_client()*
                Stops a client(s).

                You can also use the `stop()` function on a |vim.lsp.client|
                object. To stop all clients:
>

    vim.lsp.stop_client(vim.lsp.get_active_clients())
<

                By default asks the server to shutdown, unless stop was
                requested already for this client, then force-shutdown is
                attempted.

                Parameters: ~
                    {client_id}  client id or |vim.lsp.client| object, or list
                                 thereof

<

                Note: Usage of |vim.lsp.buf.document_highlight()| requires the
                following highlight groups to be defined or you won't be able
                to see the actual highlights. |LspReferenceText|

                Parameters: ~
                    {options}  (optional, table) Can be used to specify
                               FormattingOptions. Some unspecified options
                               will be automatically derived from the current
                               Neovim options.

                                           *vim.lsp.buf.formatting_seq_sync()*
formatting_seq_sync({options}, {timeout_ms}, {order})
                Formats the current buffer by sequentially requesting
                formatting from attached clients.

                Useful when multiple clients with formatting capability are
                attached.

                `*` to match one or more characters in a path segment `?` to
                match on one character in a path segment `**` to match any
                number of path segments, including none `{}` to group
                conditions (e.g. `**​/*.{ts,js}` matches all TypeScript and
                JavaScript files) `[]` to declare a range of characters to
                match in a path segment (e.g., `example.[0-9]` to match on
                `example.0` , `example.1` , …) `[!...]` to negate a range of
                characters to match in a path segment (e.g., `example.[!0-9]`
                to match on `example.a` , `example.b` , but not `example.0` )
