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|).

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 language servers using your package manager or by
     following the upstream installation instruction.

     A list of language servers is available at:

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

  2. Configure the LSP client per language server.
     A minimal example:
>lua
    vim.lsp.start({
      name = 'my-server-name',
      cmd = {'name-of-language-server-executable'},
      root_dir = vim.fs.dirname(vim.fs.find({'setup.py', 'pyproject.toml'}, { upward = true })[1]),
    })
<
     See |vim.lsp.start()| for details.

  3. Configure keymaps and autocmds to utilize LSP features.
     See |lsp-config|.

                                                        *lsp-config*

Starting a LSP client will automatically report diagnostics via
|vim.diagnostic|. Read |vim.diagnostic.config()| to learn how to customize the
display.

It also sets some buffer options if the language server supports the
functionality and if the options are otherwise empty or have the default
values set by Nvim runtime files (e.g. a ftplugin). In the latter case,
the default values are not restored when the LSP client is detached from
the buffer.

- 'omnifunc' is set to |vim.lsp.omnifunc()|. This allows to trigger completion
  using |i_CTRL-X_CTRL-O|
- 'tagfunc' is set to |vim.lsp.tagfunc()|. This enables features like
  go-to-definition, |:tjump|, and keymaps like |CTRL-]|, |CTRL-W_]|,
  |CTRL-W_}| to utilize the language server.
- 'formatexpr' is set to |vim.lsp.formatexpr()| if both 'formatprg' and
  'formatexpr' are empty. This allows to format lines via |gq| if the language
  server supports it.

To use other LSP features like hover, rename, etc. you can setup some
additional keymaps. It's recommended to setup them in a |LspAttach| autocmd to
ensure they're only active if there is a LSP client running. An example:
>lua
    vim.api.nvim_create_autocmd('LspAttach', {
      callback = function(args)
        vim.keymap.set('n', 'K', vim.lsp.buf.hover, { buffer = args.buf })
      end,
    })

<
The most used functions are:

- |vim.lsp.buf.hover()|
- |vim.lsp.buf.format()|
- |vim.lsp.buf.references()|
- |vim.lsp.buf.implementation()|
- |vim.lsp.buf.code_action()|


Not all language servers provide the same capabilities. To ensure you only set
keymaps if the language server supports a feature, you can guard the keymap
calls behind capability checks:
>lua
    vim.api.nvim_create_autocmd('LspAttach', {
      callback = function(args)
        local client = vim.lsp.get_client_by_id(args.data.client_id)
        if client.server_capabilities.hoverProvider then
          vim.keymap.set('n', 'K', vim.lsp.buf.hover, { buffer = args.buf })
        end
      end,
    })
<

To learn what capabilities are available you can run the following command in
a buffer with a started LSP client:

>vim
    :lua =vim.lsp.get_active_clients()[1].server_capabilities
<

Full list of features provided by default can be found in |lsp-buf|.

FAQ                                                     *lsp-faq*

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

     :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": >vim

     :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: Check if the function has an `async` parameter and set the value to
  false.

     E.g. code formatting: >vim

     " Auto-format *.rs (rust) files prior to saving them
     " (async = false is the default for format)
     autocmd BufWritePre *.rs lua vim.lsp.buf.format({ async = false })
<
- Q: How can I disable LSP formatting when using the |gq| command?
  A: To use the default internal formatting method and bypass the LSP client's
  'formatexpr', use |gw| instead.
  Alternatively you can completely disable LSP formatting with gq by
  unsetting 'formatexpr':

>lua
    vim.api.nvim_create_autocmd('LspAttach', {
        callback = function(args)
            vim.bo[args.buf].formatexpr = nil
        end,
    })
<
                                                           *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: >vim

    :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/showDocument
    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, result, ctx, 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|.
        {result}    (Result | Params | nil)
                        When the language server is able to successfully
                        complete a request, this contains the `result` key of
                        the response. See |lsp-response|.
        {ctx}       (table)
                        Context describes additional calling state associated
                        with the handler. It consists of the following key,
                        value pairs:

                        {method}    (string)
                                    The |lsp-method| name.
                        {client_id} (number)
                                    The ID of the |vim.lsp.client|.
                        {bufnr}     (Buffer)
                                    Buffer handle, or 0 for current.
                        {params}    (table|nil)
                                    The parameters used in the original
                                    request which resulted in this handler
                                    call.
        {config}    (table)
                        Configuration for the handler.

                        Each handler can define its 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.rpc_response_error()| to create this object.

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

  function(err, result, ctx, config)
<
    Parameters: ~
        {err}       (nil)
                        This is always `nil`.
                        See |lsp-notification|
        {result}    (Result)
                        This contains the `params` key of the notification.
                        See |lsp-notification|
        {ctx}       (table)
                        Context describes additional calling state associated
                        with the handler. It consists of the following key,
                        value pairs:

                        {method}    (string)
                                        The |lsp-method| name.
                        {client_id} (number)
                                        The ID of the |vim.lsp.client|.
        {config}    (table)
                        Configuration for the handler.

                        Each handler can define its 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: >lua

    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: >lua

    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()| >lua

    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()`:
  >lua

    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
  ||vim.lsp.diagnostic.on_publish_diagnostics()|). To override these, first
  create a reference to the existing handler: >lua

    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: >lua

    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: >lua

    vim.lsp.start_client {
      ..., -- Other configuration omitted.
      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: >lua

    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.log_levels*
Log levels are defined in |vim.log.levels|


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: >lua

    vim.lsp.protocol.TextDocumentSyncKind.Full == 1
    vim.lsp.protocol.TextDocumentSyncKind[1] == "Full"
<

                                                                *lsp-response*
For the format of the response message, see:
    https://microsoft.github.io/language-server-protocol/specifications/specification-current/#responseMessage

                                                                *lsp-notification*
For the format of the notification message, see:
    https://microsoft.github.io/language-server-protocol/specifications/specification-current/#notificationMessage

                                                                *lsp-on-list-handler*

`on_list` receives a table with:

 - `items` table[], structured like |setqflist-what|
 - `title` string, title for the list.
 - `context` table|nil. `ctx` from |lsp-handler|

This table can be used with vim.fn.setqflist or vim.fn.setloclist. E.g.:
>lua
    local function on_list(options)
      vim.fn.setqflist({}, ' ', options)
      vim.api.nvim_command('cfirst')
    end

    vim.lsp.buf.definition{on_list=on_list}
    vim.lsp.buf.references(nil, {on_list=on_list})
<
If you prefer loclist do something like this:
>lua
    local function on_list(options)
      vim.fn.setloclist(0, {}, ' ', options)
      vim.api.nvim_command('lopen')
    end
<

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*

LspSignatureActiveParameter
    Used to highlight the active parameter in the signature help. See
    |vim.lsp.handlers.signature_help()|.

------------------------------------------------------------------------------
LSP SEMANTIC HIGHLIGHTS                               *lsp-semantic-highlight*

When available, the LSP client highlights code using |lsp-semantic_tokens|,
which are another way that LSP servers can provide information about source
code.  Note that this is in addition to treesitter syntax highlighting;
semantic highlighting does not replace syntax highlighting.

The server will typically provide one token per identifier in the source code.
The token will have a `type` such as "function" or "variable", and 0 or more
`modifier`s such as "readonly" or "deprecated." The standard types and
modifiers are described here:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_semanticTokens
LSP servers may also use off-spec types and modifiers.

The LSP client adds one or more highlights for each token. The highlight
groups are derived from the token's type and modifiers:
  • `@lsp.type.<type>.<ft>` for the type
  • `@lsp.mod.<mod>.<ft>` for each modifier
  • `@lsp.typemod.<type>.<mod>.<ft>` for each modifier
Use |:Inspect| to view the highlights for a specific token. Use |:hi| or
|nvim_set_hl()| to change the appearance of semantic highlights: >vim

    hi @lsp.type.function guifg=Yellow        " function names are yellow
    hi @lsp.type.variable.lua guifg=Green     " variables in lua are green
    hi @lsp.mod.deprecated gui=strikethrough  " deprecated is crossed out
    hi @lsp.typemod.function.async guifg=Blue " async functions are blue
<
The value |vim.highlight.priorities|`.semantic_tokens` is the priority of the
`@lsp.type.*` highlights. The `@lsp.mod.*` and `@lsp.typemod.*` highlights
have priorities one and two higher, respectively.

You can disable semantic highlights by clearing the highlight groups: >lua

    -- Hide semantic highlights for functions
    vim.api.nvim_set_hl(0, '@lsp.type.function', {})

    -- Hide all semantic highlights
    for _, group in ipairs(vim.fn.getcompletion("@lsp", "highlight")) do
      vim.api.nvim_set_hl(0, group, {})
    end
<
You probably want these inside a |ColorScheme| autocommand.

Use |LspTokenUpdate| and |vim.lsp.semantic_tokens.highlight_token()| for more
complex highlighting.

The following groups are linked by default to standard |group-name|s:

After an LSP client attaches to a buffer. The |autocmd-pattern| is the
name of the buffer. When used from Lua, the client ID is passed to the
callback in the "data" table. Example: >lua

    vim.api.nvim_create_autocmd("LspAttach", {
      callback = function(args)
        local bufnr = args.buf
        local client = vim.lsp.get_client_by_id(args.data.client_id)

Just before an LSP client detaches from a buffer. The |autocmd-pattern| is the
name of the buffer. When used from Lua, the client ID is passed to the
callback in the "data" table. Example: >lua

    vim.api.nvim_create_autocmd("LspDetach", {
      callback = function(args)
        local client = vim.lsp.get_client_by_id(args.data.client_id)
        -- Do something with the client
        vim.cmd("setlocal tagfunc< omnifunc<")

<

LspTokenUpdate                                                *LspTokenUpdate*

When a visible semantic token is sent or updated by the LSP server, or when an
existing token becomes visible for the first time. The |autocmd-pattern| is
the name of the buffer. When used from Lua, the token and client ID are passed
to the callback in the "data" table. The token fields are documented in
|vim.lsp.semantic_tokens.get_at_pos()|. Example: >lua

    vim.api.nvim_create_autocmd('LspTokenUpdate', {
      callback = function(args)
        local token = args.data.token
        if token.type == 'variable' and not token.modifiers.readonly then
          vim.lsp.semantic_tokens.highlight_token(
            token, args.buf, args.data.client_id, 'MyMutableVariableHighlight'
          )
        end
      end,
    })

Note: doing anything other than calling
|vim.lsp.semantic_tokens.highlight_token()| is considered experimental.

Also the following |User| |autocommand|s are provided:

LspProgressUpdate                                          *LspProgressUpdate*
    Upon receipt of a progress notification from the server. See
    |vim.lsp.util.get_progress_messages()|.

LspRequest                                                        *LspRequest*
    After a change to the active set of pending LSP requests. See {requests}
    in |vim.lsp.client|.

Lua module: vim.lsp                                                 *lsp-core*

buf_attach_client({bufnr}, {client_id})          *vim.lsp.buf_attach_client()*
    Implements the `textDocument/did…` notifications required to track a
    buffer for any language server.

    Without calling this, the server won't be notified of changes to a buffer.

    Parameters: ~
      • {bufnr}      (integer) Buffer handle, or 0 for current
      • {client_id}  (integer) Client id

buf_detach_client({bufnr}, {client_id})          *vim.lsp.buf_detach_client()*
    Detaches client from the specified buffer. Note: While the server is
    notified that the text document (buffer) was closed, it is still able to
    send notifications should it ignore this notification.

    Parameters: ~
      • {bufnr}      (integer) Buffer handle, or 0 for current
      • {client_id}  (integer) Client id

buf_is_attached({bufnr}, {client_id})              *vim.lsp.buf_is_attached()*
    Checks if a buffer is attached for a particular client.

    Parameters: ~
      • {bufnr}      (integer) Buffer handle, or 0 for current
      • {client_id}  (integer) the client id

buf_notify({bufnr}, {method}, {params})                 *vim.lsp.buf_notify()*
    Send a notification to a server

    Parameters: ~
      • {bufnr}   (integer|nil) The number of the buffer
      • {method}  (string) Name of the request method
      • {params}  (any) Arguments to send to the server

    Return: ~
        (boolean) success true if any client returns true; false otherwise

                                                   *vim.lsp.buf_request_all()*
buf_request_all({bufnr}, {method}, {params}, {callback})
    Sends an async request for all active clients attached to the buffer.
    Executes the callback on the combined result. Parameters are the same as
    |vim.lsp.buf_request()| but the return result and callback are different.

    Parameters: ~
      • {bufnr}     (integer) Buffer handle, or 0 for current.
      • {method}    (string) LSP method name
      • {params}    (table|nil) Parameters to send to the server
      • {callback}  (function) The callback to call when all requests are
                    finished. Unlike `buf_request`, this will collect all the
                    responses from each server instead of handling them. A map
                    of client_id:request_result will be provided to the
                    callback.

    Return: ~
        fun() cancel A function that will cancel all requests

                                                  *vim.lsp.buf_request_sync()*
buf_request_sync({bufnr}, {method}, {params}, {timeout_ms})
    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.

    Parameters: ~
      • {bufnr}       (integer) Buffer handle, or 0 for current.
      • {method}      (string) LSP method name
      • {params}      (table|nil) Parameters to send to the server
      • {timeout_ms}  (integer|nil) Maximum time in milliseconds to wait for a
                      result. Defaults to 1000

    Return: ~
        (table) result Map of client_id:request_result.
        (string|nil) err On timeout, cancel, or error, `err` is a string
        describing the failure reason, and `result` is nil.

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|.
      • {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.
      • {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.

client_is_stopped({client_id})                   *vim.lsp.client_is_stopped()*
    Checks whether a client is stopped.

    Parameters: ~
      • {client_id}  (integer)

    Return: ~
        (boolean) stopped true if client is stopped, false otherwise.

                                            *vim.lsp.for_each_buffer_client()*
for_each_buffer_client({bufnr}, {fn})
    Invokes a function for each LSP client attached to a buffer.

    Parameters: ~
      • {bufnr}  (integer) Buffer number
      • {fn}     (function) Function to run on each client attached to buffer
                 {bufnr}. The function takes the client, client ID, and buffer
                 number as arguments. Example: >lua

                   vim.lsp.for_each_buffer_client(0, function(client, client_id, bufnr)
                     print(vim.inspect(client))
                   end)
<

formatexpr({opts})                                      *vim.lsp.formatexpr()*
    Provides an interface between the built-in client and a `formatexpr`
    function.

    Currently only supports a single client. This can be set via `setlocal
    formatexpr=v:lua.vim.lsp.formatexpr()` but will typically or in
    `on_attach` via `vim.api.nvim_buf_set_option(bufnr, 'formatexpr',
    'v:lua.vim.lsp.formatexpr(#{timeout_ms:250})')`.

    Parameters: ~
      • {opts}  (table) options for customizing the formatting expression
                which takes the following optional keys:
                • timeout_ms (default 500ms). The timeout period for the

    Level numbers begin with "TRACE" at 0

    Use `lsp.log_levels` for reverse lookup.

    Parameters: ~
      • {level}  (integer|string) the case insensitive level name or number

    See also: ~
      • |vim.lsp.log_levels|

start({config}, {opts})                                      *vim.lsp.start()*
    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 (in list form) used to start the language server. Must be
      absolute, or found on `$PATH`. Shell constructs like `~` are not
      expanded.
    • `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
    `ftplugin/<filetype_name>.lua` (See |ftplugin-name|)

    Parameters: ~
      • {config}  (table) Same configuration as documented in
                  |vim.lsp.start_client()|
      • {opts}    nil|table Optional keyword arguments:
                  • reuse_client (fun(client: client, config: table): boolean)
                    Predicate used to decide if a client should be re-used.
                    Used on all running clients. The default implementation
                    re-uses a client if name and root_dir matches.
                  • bufnr (number) Buffer handle to attach to if starting or
                    re-using a client (0 for current).

    Return: ~
        (number|nil) client_id

start_client({config})                                *vim.lsp.start_client()*
    Starts and initializes a client with the given configuration.

    Field `cmd` in {config} is required.

    Parameters: ~
      • {config}  (table) Configuration for the server:
                  • cmd: (table|string|fun(dispatchers: table):table) command
                    string or list treated like |jobstart()|. The command must
                    launch the language server process. `cmd` can also be a
                    function that creates an RPC client. The function receives
                    a dispatchers table and must return a table with the
                    functions `request`, `notify`, `is_closing` and
                    `terminate` See |vim.lsp.rpc.request()| and
                    |vim.lsp.rpc.notify()| For TCP there is a built-in 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 map-like table.
                    Non-string values are coerced to string. Example: >

                       { PORT = 8080; HOST = "0.0.0.0"; }
<
                  • 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. 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 "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 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: >lua

     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}  integer|table id or |vim.lsp.client| object, or list
                     thereof

tagfunc({...})                                             *vim.lsp.tagfunc()*
    Provides an interface between the built-in client and 'tagfunc'.

    When used with normal mode commands (e.g. |CTRL-]|) this will invoke the
    "textDocument/definition" LSP method to find the tag under the cursor.
    Otherwise, uses "workspace/symbol". If no results are returned from any
    LSP servers, falls back to using built-in tags.

    Parameters: ~
      • {pattern}  (string) Pattern used to find a workspace symbol
      • {flags}    (string) See |tag-function|

    Return: ~
        table[] tags A list of matching tags

with({handler}, {override_config})                            *vim.lsp.with()*

                   • formatting_options (table|nil): Can be used to specify
                     FormattingOptions. Some unspecified options will be
                     automatically derived from the current Neovim options.
                     See https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#formattingOptions
                   • timeout_ms (integer|nil, default 1000): Time in

                   • bufnr (number|nil): Restrict formatting to the clients
                     attached to the given buffer, defaults to the current
                     buffer (0).
                   • filter (function|nil): Predicate used to filter clients.
                     Receives a client as argument and must return a boolean.
                     Clients matching the predicate are included. Example:               • >lua

highlight_token({token}, {bufnr}, {client_id}, {hl_group}, {opts})
    Highlight a semantic token.

    Apply an extmark with a given highlight group for a semantic token. The
    mark will be deleted by the semantic token engine when appropriate; for
    example, when the LSP sends updated tokens. This function is intended for
    use inside |LspTokenUpdate| callbacks.

    Parameters: ~
      • {token}      (table) a semantic token, found as `args.data.token` in
                     |LspTokenUpdate|.
      • {bufnr}      (integer) the buffer to highlight
      • {client_id}  (integer) The ID of the |vim.lsp.client|
      • {hl_group}   (string) Highlight group name
      • {opts}       (table|nil) Optional parameters.
                     • priority: (integer|nil) Priority for the applied
                       extmark. Defaults to
                       `vim.highlight.priorities.semantic_tokens + 3`

start({bufnr}, {client_id}, {opts})          *vim.lsp.semantic_tokens.start()*
    Start the semantic token highlighting engine for the given buffer with the
    given client. The client must already be attached to the buffer.

    NOTE: This is currently called automatically by
    |vim.lsp.buf_attach_client()|. To opt-out of semantic highlighting with a
    server that supports it, you can delete the semanticTokensProvider table
    from the {server_capabilities} of your client in your |LspAttach| callback
    or your configuration's `on_attach` callback: >lua

       client.server_capabilities.semanticTokensProvider = nil
<

    Parameters: ~
      • {bufnr}      (integer)
      • {client_id}  (integer)
      • {opts}       (nil|table) Optional keyword arguments
                     • debounce (integer, default: 200): Debounce token
                       requests to the server by the given number in
                       milliseconds

stop({bufnr}, {client_id})                    *vim.lsp.semantic_tokens.stop()*
    Stop the semantic token highlighting engine for the given buffer with the
    given client.

    NOTE: This is automatically called by a |LspDetach| autocmd that is set up
    as part of `start()`, so you should only need this function to manually
    disengage the semantic token engine without fully detaching the LSP client
    from the buffer.

    Parameters: ~
      • {bufnr}      (integer)
      • {client_id}  (integer)
