- remove redundant autocmd list
This "grouped" list is useless, it only gets in the way when searching
for event names.
- intro.txt: cleanup
- starting.txt: update, revisit
- doc: `:help bisect`
- mbyte.txt: update aliases 1656367b90. closes #11960
- options: remove 'guifontset'. Why:
- It is complicated and is used by almost no one.
- It is unlikely to be implemented by Nvim GUIs (complicated to parse,
specific to Xorg...).

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 a LSP client, but the servers are provided by third parties.
|
||
Follow these steps to get LSP features:
|
||
|
||
1. Install the nvim-lsp plugin. It provides common configuration for
|
||
various servers so you can get started quickly.
|
||
https://github.com/neovim/nvim-lsp
|
||
2. Install a language server. Try ":LspInstall <tab>" or use your system
|
||
package manager to install the relevant language server:
|
||
https://microsoft.github.io/language-server-protocol/implementors/servers/
|
||
3. Add `nvim_lsp.xx.setup{…}` to your vimrc, where "xx" is the name of the
|
||
relevant config. See the nvim-lsp README for details.
|
||
|
||
To check LSP clients 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 want to use other features like
|
||
go-to-definition, hover, etc. Example config: >
|
||
|
||
nnoremap <silent> gd <cmd>lua vim.lsp.buf.declaration()<CR>
|
||
nnoremap <silent> <c-]> <cmd>lua vim.lsp.buf.definition()<CR>
|
||
nnoremap <silent> K <cmd>lua vim.lsp.buf.hover()<CR>
|
||
nnoremap <silent> gD <cmd>lua vim.lsp.buf.implementation()<CR>
|
||
nnoremap <silent> <c-k> <cmd>lua vim.lsp.buf.signature_help()<CR>
|
||
nnoremap <silent> 1gD <cmd>lua vim.lsp.buf.type_definition()<CR>
|
||
nnoremap <silent> gr <cmd>lua vim.lsp.buf.references()<CR>
|
||
nnoremap <silent> g0 <cmd>lua vim.lsp.buf.document_symbol()<CR>
|
||
nnoremap <silent> gW <cmd>lua vim.lsp.buf.workspace_symbol()<CR>
|
||
|
||
Nvim provides the |vim.lsp.omnifunc| 'omnifunc' handler which allows
|
||
|i_CTRL-X_CTRL-O| to consume LSP completion. Example config (note the use of
|
||
|v:lua| to call Lua from Vimscript): >
|
||
|
||
" Use LSP omni-completion in Python files.
|
||
autocmd Filetype python setlocal omnifunc=v:lua.vim.lsp.omnifunc
|
||
|
||
If a function has a `*_sync` variant, it's primarily intended for being run
|
||
automatically on file save. E.g. code formatting: >
|
||
|
||
" Auto-format *.rs files prior to saving them
|
||
autocmd BufWritePre *.rs lua vim.lsp.buf.formatting_sync(nil, 1000)

|
||
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".
|
||
|
||
================================================================================
|
||
LSP API *lsp-api*
|
||
|
||
The `vim.lsp` Lua module is a framework for building LSP plugins.
|
||
|
||
1. Start with |vim.lsp.start_client()| and |vim.lsp.buf_attach_client()|.
|
||
2. Peek at the API: >
|
||
:lua print(vim.inspect(vim.lsp))
|
||
< 3. See |lsp-extension-example| for a full example.
|
||
|
||
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 callbacks.
|
||
|lsp-callbacks| The `vim.lsp.callbacks` table defines default callbacks used
|
||
when creating a new client. Keys are LSP method names: >
|
||
|
||
:lua print(vim.inspect(vim.tbl_keys(vim.lsp.callbacks)))
|
||
|
||
These LSP requests/notifications are defined by default:
|
||
|
||
textDocument/publishDiagnostics
|
||
window/logMessage
|
||
window/showMessage
|
||
|
||
You can check these via `vim.tbl_keys(vim.lsp.callbacks)`.
|
||
|
||
These will be used preferentially in `vim.lsp.buf_…` methods for handling
|
||
requests. They will also be used when responding to server requests and
|
||
notifications.
|
||
|
||
Use cases:
|
||
- Users can modify this to customize to their preferences.
|
||
- UI plugins can modify this by assigning to
|
||
`vim.lsp.callbacks[method]` so as to provide more specialized
|
||
handling, allowing you to leverage the UI capabilities available. UIs should
|
||
try to be conscientious of any existing changes the user may have set
|
||
already by checking for existing values.
|
||
|
||
Any callbacks passed directly to `request` methods on a server client will
|
||
have the highest precedence, followed by the `callbacks`.
|
||
|
||
You can override the default handlers,
|
||
- globally: by modifying the `vim.lsp.callbacks` table
|
||
- per-client: by passing the {callbacks} table parameter to
|
||
|vim.lsp.start_client|
|
||
|
||
Each handler has this signature: >
|
||
|
||
function(err, method, params, client_id)
|
||
|
||
Callbacks are functions which are called in a variety of situations by the
|
||
client. Their signature is `function(err, method, params, client_id)` They can
|
||
be set by the {callbacks} parameter for |vim.lsp.start_client| or via the
|
||
|vim.lsp.callbacks|.
|
||
|
||
Handlers are called for:
|
||
- Notifications from the server (`err` is always `nil`).
|
||
- Requests initiated by the server (`err` is always `nil`).
|
||
The 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.
|
||
- Handling requests initiated by the client if the request doesn't explicitly
|
||
specify a callback (such as in |vim.lsp.buf_request|).
|
||
|
||
|
||
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: >
|
||
|
||
vim.lsp.protocol.TextDocumentSyncKind.Full == 1
|
||
vim.lsp.protocol.TextDocumentSyncKind[1] == "Full"

LSP EXAMPLE *lsp-extension-example*
|
||
|
||
This example is for plugin authors or users who want a lot of control. If you
|
||
are just getting started see |lsp-quickstart|.
|
||
|
||
For more advanced configurations where just filtering by filetype isn't
|
||
sufficient, you can use the `vim.lsp.start_client()` and
|
||
`vim.lsp.buf_attach_client()` commands to easily customize the configuration
|
||
however you please. For example, if you want to do your own filtering, or
|
||
start a new LSP client based on the root directory for if you plan to work
|
||
with multiple projects in a single session. Below is a fully working Lua
|
||
example which can do exactly that.
|
||
|
||
The example will:
|
||
1. Check for each new buffer whether or not we want to start an LSP client.
|
||
2. Try to find a root directory by ascending from the buffer's path.
|
||
3. Create a new LSP for that root directory if one doesn't exist.
|
||
4. Attach the buffer to the client for that root directory.

||
Return: ~
|
||
Map of client_id:request_result. On timeout, cancel or
|
||
error, returns `(nil, err)` where `err` is a string
|
||
describing the failure reason.
|
||
|
||
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, [callback], bufnr) Send a request
|
||
to the server. This is a thin wrapper around
|
||
{client.rpc.request} with some additional checking. If
|
||
{callback} is not specified, it will use
|
||
{client.callbacks} to try to find a callback. 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.
|
||
• notify(method, params) Send 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]) Stop 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(bufnr) Runs the on_attach function from the
|
||
client's config if it was defined.
|
||
|
||
• 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.
|
||
• {callbacks} (table): The callbacks used by the client as
|
||
described in |lsp-callbacks|.
|
||
• {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
|

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.
|
||
{callbacks} Map of language server method names to `function(err, method, params,
|
||
client_id)` handler. Invoked for:
|
||
• Notifications to the server, where
|
||
`err` will always be `nil` .
|
||
• Requests by the server. For these you
|
||
can respond by returning two values:
|
||
`result, err` where err must be
|
||
shaped like a RPC error, i.e. `{
|
||
code, message, data? }` . Use
|
||
|vim.lsp.rpc_response_error()| to
|
||
help with this.
|
||
• Default callback for client requests
|
||
not explicitly specifying a callback.
|
||
{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.
|
||
{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.
|
||
{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"
|
||
|
||
Return: ~
|
||
Client id. |vim.lsp.get_client_by_id()| Note: client is
|
||
only available after it has been initialized, which may
|
||
happen after a small delay (or never if there is an
|
||
error). 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
