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. You can find language servers here:
|
|
https://microsoft.github.io/language-server-protocol/implementors/servers/
|
|
|
|
2. Configure the LSP client per language server. See |vim.lsp.start()| or use
|
|
this minimal example as a guide: >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]),
|
|
})
|
|
<
|
|
3. Check that the server attached to the buffer: >
|
|
:lua =vim.lsp.get_clients()
|
|
|
|
4. Configure keymaps and autocmds to use LSP features. See |lsp-config|.
|
|
|
|
*lsp-config*
|
|
*lsp-defaults*
|
|
When the LSP client starts it enables diagnostics |vim.diagnostic| (see
|
|
|vim.diagnostic.config()| to customize). It also sets various default options,
|
|
listed below, if (1) the language server supports the functionality and (2)
|
|
the options are empty or were set by the builtin runtime (ftplugin) files. The
|
|
options are not restored when the LSP client is stopped or detached.
|
|
|
|
- 'omnifunc' is set to |vim.lsp.omnifunc()|, use |i_CTRL-X_CTRL-O| to trigger
|
|
completion.
|
|
- '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()|, so you can format lines via
|
|
|gq| if the language server supports it.
|
|
- To opt out of this use |gw| instead of gq, or set 'formatexpr' on LspAttach.
|
|
- |K| is mapped to |vim.lsp.buf.hover()| unless |'keywordprg'| is customized or
|
|
a custom keymap for `K` exists.
|
|
|
|
*lsp-defaults-disable*
|
|
To override the above defaults, set or unset the options on |LspAttach|: >lua
|
|
vim.api.nvim_create_autocmd('LspAttach', {
|
|
callback = function(ev)
|
|
vim.bo[ev.buf].formatexpr = nil
|
|
vim.bo[ev.buf].omnifunc = nil
|
|
vim.keymap.del("n", "K", { buffer = ev.buf })
|
|
end,
|
|
})
|
|
|
|
To use other LSP features like hover, rename, etc. you can set other keymaps
|
|
on |LspAttach|. 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 common 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_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_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: 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 })
|
|
<
|
|
*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|).
|
|
*lsp-method*
|
|
|
|
Requests and notifications defined by the LSP specification are referred to as
|
|
"LSP methods". The Nvim LSP client provides default handlers in the global
|
|
|vim.lsp.handlers| table, you can list them with this command: >vim
|
|
|
|
:lua vim.print(vim.tbl_keys(vim.lsp.handlers))
|
|
<
|
|
They are also listed below. Note that handlers depend on server support: they
|
|
won't run if your server doesn't support them.

*lsp-handler*
|
|
LSP handlers are functions that handle |lsp-response|s to requests made by Nvim
|
|
to the server. (Notifications, as opposed to requests, are fire-and-forget:
|
|
there is no response, so they can't be handled. |lsp-notification|)
|
|
|
|
Each response handler has this signature: >
|
|
|
|
function(err, result, ctx, config)
|
|
<
|
|
Parameters: ~
|
|
- {err} (table|nil) Error info dict, or `nil` if the request
|
|
completed.
|
|
- {result} (Result | Params | nil) `result` key of the |lsp-response| or
|
|
`nil` if the request failed.
|
|
- {ctx} (table) Table of calling state associated with the
|
|
handler, with these keys:
|
|
- {method} (string) |lsp-method| name.
|
|
- {client_id} (number) |vim.lsp.client| identifier.
|
|
- {bufnr} (Buffer) Buffer handle.
|
|
- {params} (table|nil) Request parameters table.
|
|
- {version} (number) Document version at time of
|
|
request. Handlers can compare this to the
|
|
current document version to check if the
|
|
response is "stale". See also |b:changedtick|.
|
|
- {config} (table) Handler-defined configuration table, which allows
|
|
users to customize handler behavior.
|
|
For an example, see:
|
|
|vim.lsp.diagnostic.on_publish_diagnostics()|
|
|
To configure a particular |lsp-handler|, see:
|
|
|lsp-handler-configuration|
|
|
|
|
Returns: ~
|
|
Two values `result, err` where `err` is shaped like an RPC error: >
|
|
{ code, message, data? }
|
|
< You can use |vim.lsp.rpc.rpc_response_error()| to create this object.
|
|
|
|
*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 of |vim.lsp.start()|. This sets the default
|
|
|lsp-handler| for the server being started. Example: >lua
|
|
|
|
vim.lsp.start {
|
|
..., -- Other configuration omitted.
|
|
handlers = {
|
|
["textDocument/definition"] = my_custom_server_definition
|
|
},
|
|
}
|
|
|
|
- The {handler} parameter of |vim.lsp.buf_request_all()|. This sets
|
|
the |lsp-handler| ONLY for the given request(s). Example: >lua
|
|
|
|
vim.lsp.buf_request_all(
|
|
0,
|
|
"textDocument/definition",
|
|
my_request_params,
|
|
my_handler
|
|
)
|
|
<
|
|
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_all()|, if any.
|
|
2. Handler defined in |vim.lsp.start()|, 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*
|
|
LSP response shape:
|
|
https://microsoft.github.io/language-server-protocol/specifications/specification-current/#responseMessage
|
|
|
|
*lsp-notification*
|
|
LSP notification shape:
|
|
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*
|
|
LspReferenceText used for highlighting "text" references
|
|
*hl-LspReferenceRead*
|
|
LspReferenceRead used for highlighting "read" references
|
|
*hl-LspReferenceWrite*
|
|
LspReferenceWrite used for highlighting "write" references
|
|
*hl-LspInlayHint*
|
|
LspInlayHint used for highlighting inlay hints
|
|
|
|
|
|
*lsp-highlight-codelens*
|
|
|
|
Highlight groups related to |lsp-codelens| functionality.
|
|
|
|
*hl-LspCodeLens*
|
|
LspCodeLens
|
|
Used to color the virtual text of the codelens. See
|
|
|nvim_buf_set_extmark()|.
|
|
|
|
LspCodeLensSeparator *hl-LspCodeLensSeparator*
|
|
Used to color the separator between two or more code lenses.
|
|
|

|
|
|
|
*hl-LspSignatureActiveParameter*
|
|
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/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:

@lsp.type.class Structure
|
|
@lsp.type.decorator Function
|
|
@lsp.type.enum Structure
|
|
@lsp.type.enumMember Constant
|
|
@lsp.type.function Function
|
|

EVENTS *lsp-events*
|
|
|
|
LspAttach *LspAttach*
|
|
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)
|
|
if client.server_capabilities.completionProvider then
|
|
vim.bo[bufnr].omnifunc = "v:lua.vim.lsp.omnifunc"
|
|
end
|
|
if client.server_capabilities.definitionProvider then
|
|
vim.bo[bufnr].tagfunc = "v:lua.vim.lsp.tagfunc"
|
|
end
|
|
end,
|
|
})
|
|
<
|
|
|
|
LspDetach *LspDetach*
|
|
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<")
|
|
end,
|
|
})
|
|
<
|
|
|
|
LspNotify *LspNotify*
|
|
This event is triggered after each successful notification sent to an
|
|
LSP server.
|
|
|
|
When used from Lua, the client_id, LSP method, and parameters are sent
|
|
in the "data" table. Example: >lua
|
|
|
|
vim.api.nvim_create_autocmd('LspNotify', {
|
|
callback = function(args)
|
|
local bufnr = args.buf
|
|
local client_id = args.data.client_id
|
|
local method = args.data.method
|
|
local params = args.data.params
|
|
|
|
-- do something with the notification
|
|
if method == 'textDocument/...' then
|
|
update_buffer(bufnr)
|
|
end
|
|
end,
|
|
})
|
|
<
|
|
|
|
LspProgress *LspProgress*
|
|
Upon receipt of a progress notification from the server. Notifications can
|
|
be polled from a `progress` ring buffer of a |vim.lsp.client| or use
|
|
|vim.lsp.status()| to get an aggregate message
|
|
|
|
If the server sends a "work done progress", the `pattern` is set to `kind`
|
|
(one of `begin`, `report` or `end`).
|
|
|
|
When used from Lua, the event contains a `data` table with `client_id` and
|
|
`result` properties. `result` will contain the request params sent by the
|
|
server.
|
|
|
|
Example: >vim
|
|
autocmd LspProgress * redrawstatus
|
|
<
|
|
|
|
LspRequest *LspRequest*
|
|
For each request sent to an LSP server, this event is triggered for
|
|
every change to the request's status. The status can be one of
|
|
`pending`, `complete`, or `cancel` and is sent as the {type} on the
|
|
"data" table passed to the callback function.
|
|
|
|
It triggers when the initial request is sent ({type} == `pending`) and
|
|
when the LSP server responds ({type} == `complete`). If a cancellation
|
|
is requested using `client.cancel_request(request_id)`, then this event
|
|
will trigger with {type} == `cancel`.
|
|
|
|
When used from Lua, the client ID, request ID, and request are sent in
|
|
the "data" table. See {requests} in |vim.lsp.client| for details on the
|
|
{request} value. If the request type is `complete`, the request will be
|
|
deleted from the client's pending requests table immediately after
|
|
calling the event's callbacks. Example: >lua
|
|
|
|
vim.api.nvim_create_autocmd('LspRequest', {
|
|
callback = function(args)
|
|
local bufnr = args.buf
|
|
local client_id = args.data.client_id
|
|
local request_id = args.data.request_id
|
|
local request = args.data.request
|
|
if request.type == 'pending' then
|
|
-- do something with pending requests
|
|
track_pending(client_id, bufnr, request_id, request)
|
|
elseif request.type == 'cancel' then
|
|
-- do something with pending cancel requests
|
|
track_canceling(client_id, bufnr, request_id, request)
|
|
elseif request.type == 'complete' then
|
|
-- do something with finished requests. this pending
|
|
-- request entry is about to be removed since it is complete
|
|
track_finish(client_id, bufnr, request_id, request)
|
|
end
|
|
end,
|
|
})
|
|
<
|
|
|
|
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.

|
|
|
|
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_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|.
|
|
• {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): 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.
|
|
• {progress} A ring buffer (|vim.ringbuf()|) containing progress
|
|
messages sent by the server.
|
|
|
|
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.
|
|
|
|
commands *vim.lsp.commands*
|
|
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|
|
|
|
|
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.bo[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
|
|
formatting request.

|
|
|
|

|
|
|
|
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 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
|
|
`ftplugin/<filetype_name>.lua` (See |ftplugin-name|)
|
|
|
|
Parameters: ~
|
|
• {config} (`table`) Same configuration as documented in
|
|
|vim.lsp.start_client()|
|
|
• {opts} (`lsp.StartOpts?`) 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: ~
|
|
(`integer?`) 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} (`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: >
|
|
|
|
{ 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. Nvim
|
|
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?`) 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.
|
|
|
|
status() *vim.lsp.status()*
|
|
Consumes the latest progress messages from all clients and formats them as
|
|
a string. Empty if there are no clients or if no new messages
|
|
|
|
Return: ~
|
|
(`string`)
|
|
|
|
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_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
|
|
• {force} (`boolean?`) shutdown forcefully
|
|
|
|
tagfunc({pattern}, {flags}) *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

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?`) 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} (`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`)
