|
--- LSP client object. You can get an active client object via
|
|
--- |vim.lsp.get_client_by_id()| or |vim.lsp.get_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.
|
|
---
|
|
--- - supports_method(method, [opts]): boolean
|
|
--- Checks if a client supports a given method.
|
|
--- Always returns true for unknown off-spec methods.
|
|
--- [opts] is a optional `{bufnr?: integer}` table.
|
|
--- Some language server capabilities can be file specific.
|
|
---
|
|
--- - 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|.
|
|
---
|
|
--- - {commands} (table): Table of command name to function which is called if
|
|
--- any LSP action (code action, code lenses, ...) triggers the command.
|
|
--- Client commands take precedence over the global command registry.
|
|
---
|
|
--- - {requests} (table): The current pending requests in flight
|
|
--- to the server. Entries are key-value pairs with the key
|
|
--- being the request ID while the value is a table with `type`,
|
|
--- `bufnr`, and `method` key-value pairs. `type` is either "pending"
|
|
--- for an active request, or "cancel" for a cancel request. It will
|
|
--- be "complete" ephemerally while executing |LspRequest| autocmds
|
|
--- when replies are received from the server.
|
|
---
|
|
--- - {config} (table): Reference 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.
|
|
---
|
|
--- - {progress} A ring buffer (|vim.ringbuf()|) containing progress messages
|
|
--- sent by the server.
|
|
---
|
|
--- - {settings} Map with language server specific settings.
|
|
--- See {config} in |vim.lsp.start_client()|
|
|
---
|
|
--- - {flags} A table with flags for the client. See {config} in |vim.lsp.start_client()|

|
--- Create a new LSP client and start a language server or reuses an already
|
|
--- running client if one is found matching `name` and `root_dir`.
|
|
--- Attaches the current buffer to the client.
|
|
---
|
|
--- Example:
|
|
---
|
|
--- ```lua
|
|
--- vim.lsp.start({
|
|
--- name = 'my-server-name',
|
|
--- cmd = {'name-of-language-server-executable'},
|
|
--- root_dir = vim.fs.dirname(vim.fs.find({'pyproject.toml', 'setup.py'}, { upward = true })[1]),
|
|
--- })
|
|
--- ```
|
|
---
|
|
--- See |vim.lsp.start_client()| for all available options. The most important are:
|
|
---
|
|
--- - `name` arbitrary name for the LSP client. Should be unique per language server.
|
|
--- - `cmd` command string[] or function, described at |vim.lsp.start_client()|.
|
|
--- - `root_dir` path to the project root. By default this is used to decide if an existing client
|
|
--- should be re-used. The example above uses |vim.fs.find()| and |vim.fs.dirname()| to detect the
|
|
--- root by traversing the file system upwards starting from the current directory until either
|
|
--- a `pyproject.toml` or `setup.py` file is found.
|
|
--- - `workspace_folders` list of `{ uri:string, name: string }` tables specifying the project root
|
|
--- folders used by the language server. If `nil` the property is derived from `root_dir` for
|
|
--- convenience.
|
|
---
|
|
--- Language servers use this information to discover metadata like the
|
|
--- dependencies of your project and they tend to index the contents within the
|
|
--- project folder.
|
|
---
|
|
---
|
|
--- To ensure a language server is only started for languages it can handle,
|
|
--- make sure to call |vim.lsp.start()| within a |FileType| autocmd.
|
|
--- Either use |:au|, |nvim_create_autocmd()| or put the call in a

|
|
--- Starts and initializes a client with the given configuration.
|
|
---
|
|
--- Field `cmd` in {config} is required.
|
|
---
|
|
---@param config (lsp.ClientConfig) Configuration for the server:
|
|
--- - cmd: (string[]|fun(dispatchers: table):table) command string[] that launches the language
|
|
--- server (treated as in |jobstart()|, must be absolute or on `$PATH`, shell constructs like
|
|
--- "~" are not expanded), or function that creates an RPC client. Function receives
|
|
--- a `dispatchers` table and returns a table with member functions `request`, `notify`,
|
|
--- `is_closing` and `terminate`.
|
|
--- See |vim.lsp.rpc.request()|, |vim.lsp.rpc.notify()|.
|
|
--- For TCP there is a builtin RPC client factory: |vim.lsp.rpc.connect()|
|
|
---
|
|
--- - 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. Must be specified using a table.
|
|
--- Non-string values are coerced to string.
|
|
--- Example:
|
|
--- <pre>
|
|
--- { PORT = 8080; HOST = "0.0.0.0"; }
|
|
--- </pre>
|
|
---
|
|
--- - detached: (boolean, default true) Daemonize the server process so that it runs in a
|
|
--- separate process group from Nvim. Nvim will shutdown the process on exit, but if Nvim fails to
|
|
--- exit cleanly this could leave behind orphaned server processes.
|
|
---
|
|
--- - workspace_folders: (table) List of workspace folders passed to the
|
|
--- language server. For backwards compatibility rootUri and rootPath will be
|
|
--- derived from the first workspace folder in this list. See `workspaceFolders` in
|
|
--- the LSP spec.
|
|
---
|
|
--- - 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.empty_dict()|, else it will be encoded as an
|
|
--- array.
|
|
---
|
|
--- - handlers: Map of language server method names to |lsp-handler|
|
|
---
|
|
--- - settings: Map with language server specific settings. These are
|
|
--- returned to the language server if requested via `workspace/configuration`.
|
|
--- Keys are case-sensitive.
|
|
---
|
|
--- - commands: table Table that maps string of clientside commands to user-defined functions.
|
|
--- Commands passed to start_client take precedence over the global command registry. Each key
|
|
--- must be a unique command name, and the value is a function which is called if any LSP action
|
|
--- (code action, code lenses, ...) triggers the command.
|
|
---
|
|
--- - 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.
|
|
---
|
|
--- - 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.rpc.client_errors` for possible errors.
|
|
--- Use `vim.lsp.rpc.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.
|
|
---
|
|
--- - 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 "off"
|
|
---
|
|
--- - 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 150): Debounce didChange
|
|
--- notifications to the server by the given number in milliseconds. No debounce
|
|
--- occurs if nil
|
|
--- - exit_timeout (number|boolean, default false): Milliseconds to wait for server to
|
|
--- exit cleanly after sending the "shutdown" request before sending kill -15.
|
|
--- If set to false, nvim exits immediately after sending the "shutdown" request to the server.
|
|
---
|
|
--- - root_dir: (string) Directory where the LSP
|
|
--- server will base its workspaceFolders, rootUri, and rootPath
|
|
--- on initialization.
|
|
---
|
|
---@return integer|nil client_id. |vim.lsp.get_client_by_id()| Note: client may not be

--- Registry for client side commands.
|
|
--- This is an extension point for plugins to handle custom commands which are
|
|
--- not part of the core language server protocol specification.
|
|
---
|
|
--- The registry is a table where the key is a unique command name,
|
|
--- and the value is a function which is called if any LSP action
|
|
--- (code action, code lenses, ...) triggers the command.
|
|
---
|
|
--- If a LSP response contains a command for which no matching entry is
|
|
--- available in this registry, the command will be executed via the LSP server
|
|
--- using `workspace/executeCommand`.
|
|
---
|
|
--- The first argument to the function will be the `Command`:
|
|
--- Command
|
|
--- title: String
|
|
--- command: String
|
|
--- arguments?: any[]
|
|
---
|
|
--- The second argument is the `ctx` of |lsp-handler|
|
|
--- @type table<string,function>
