INTRODUCTION *vim-lsp-introduction*
Async Language Server Protocol (LSP) for Vim 8 and Neovim.
For more information on LSP refer to the official website at
https://microsoft.github.io/language-server-protocol/
================================================================================
INSTALL *vim-lsp-install*
Install the async.vim and vim-lsp plugins. Below is a sample using plug.vim
Plug 'prabirshrestha/async.vim'
Plug 'prabirshrestha/vim-lsp'
Note: async.vim (https://github.com/prabirshrestha/async.vim) is required to
use vim-lsp. It is used to normalize the jobs api between Vim 8 and Neovim.
===============================================================================
LANGUAGE SERVERS *vim-lsp-language-servers*
CONFIGURE *vim-lsp-configure*
vim-lsp doesn't ship with any language servers. The user is responsible for
configuring the language servers correctly.
Here is an example of configuring the python language server protocol based
on pyls (https://github.com/palantir/python-language-server)
1. Make sure the language server is available locally in the machine.
For python, pip package manager can be used to install the language server.
pip install python-language-server
2. Register the language server in your .vimrc
if (executable('pyls'))
au User lsp_setup call lsp#register_server({
\ 'name': 'pyls',
\ 'cmd': {server_info->['pyls']},
\ 'whitelist': ['python']
\ })
endif
For more details refer to |vim-lsp-register_server|.
WIKI *vim-lsp-configure-wiki*
For documentation on how to configure other language servers refer
to https://github.com/prabirshrestha/vim-lsp/wiki/Servers
===============================================================================
Options *vim-lsp-options*
g:lsp_diagnostics_enabled *g:lsp_diagnostics_enabled*
Type: |Number|
Default: `1`
Enable support for document diagnostics like warnings and error messages.
enabling vim-lsp during startup. Refer to |g:lsp_signs_enabled| to enable
signs column.
Example:
let g:lsp_diagnostics_enabled = 1
let g:lsp_diagnostics_enabled = 0
g:lsp_auto_enable *g:lsp_auto_enable*
Type: |Number|
Default: `1`
Auto enable vim-lsp plugin during startup. Set to `0` to disable auto
enabling vim-lsp during startup.
Example:
let g:lsp_auto_enable = 1
let g:lsp_auto_enable = 0
g:lsp_preview_keep_focus *g:lsp_preview_keep_focus*
Type: |Number|
Default: `1`
Indicates whether to keep the focus on current window or move the focus
to the |preview-window| when a |preview-window| is opened by vim-lsp.
Certain commands such as |LspHover| opens the result in a |preview-window|.
Example:
" Keep the focus in current window
let g:lsp_preview_keep_focus = 1
" Do not keep the focus in current window.
" Move the focus to |preview-window|.
let g:lsp_preview_keep_focus = 0
* |preview-window| can be closed using the default vim mapping - `<c-w><c-z>`.
g:lsp_preview_float *g:lsp_preview_float*
Type: |Number|
Default: `1`
If set and nvim_win_open() or popup_create is available, hover information
are shown in a floating window as |preview-window| at the cursor position.
The |preview-window| is closed automatically on cursor moves, unless it is
focused. While focused it may be closed with <esc>.
This feature requires neovim 0.4.0 (current master) or
Vim8.1 with has('patch-8.1.1517').
Example:
>
" Opens preview windows as floating
let g:lsp_preview_float = 1
" Opens preview windows as normal windows
let g:lsp_preview_float = 0
<
After opening an autocmd User event lsp_float_opened is issued, as well as
and lsp_float_closed upon closing. This can be used to alter the preview
window (using lsp#ui#vim#output#getpreviewwinid() to get the window id),
setup custom bindings while a preview is open, or change the highlighting
of the window.
Example of custom keybindings:
>
" Close preview window with <esc>
autocmd User lsp_float_opened nmap <buffer> <silent> <esc>
\ <Plug>(lsp-preview-close)
autocmd User lsp_float_closed nunmap <buffer> <esc>
<
Example of customising the highlighting:
>
highlight PopupWindow ctermbg=lightblue guibg=lightblue
augroup lsp_float_colours
autocmd!
if !has('nvim')
autocmd User lsp_float_opened
\ call win_execute(lsp#ui#vim#output#getpreviewwinid(),
\ 'setlocal wincolor=PopupWindow')
else
autocmd User lsp_float_opened
\ call nvim_win_set_option(lsp#ui#vim#output#getpreviewwinid(),
\ 'winhighlight', 'Normal:PopupWindow')
endif
augroup end
<
g:lsp_preview_autoclose *g:lsp_preview_autoclose*
Type: |Number|
Default: `1`
Indicates if an opened floating preview shall be automatically closed upon
movement of the cursor. If set to 1, the window will close automatically if
the cursor is moved and the preview is not focused. If set to 0, it will
remain open until explicitly closed (e.g. with <plug>(lsp-preview-close),
or <ESC> when focused).
Example:
" Preview closes on cursor move
let g:lsp_preview_autoclose = 1
" Preview remains open and waits for an explicit call
let g:lsp_preview_autoclose = 0
g:lsp_preview_doubletap *g:lsp_preview_doubletap*
Type: |List|
Default: `[function('lsp#ui#vim#output#focuspreview')]`
When preview is called twice with the same data while the preview is still
open, the function in `lsp_preview_doubletap` is called instead. To disable
this and just "refresh" the preview, set to ´0´.
Example:
" Focus preview on repeated preview (does not work for vim8.1 popups)
let g:lsp_preview_doubletap = [function('lsp#ui#vim#output#focuspreview')]
" Closes the preview window on the second call to preview
let g:lsp_preview_doubletap = [function('lsp#ui#vim#output#closepreview')]
" Disables double tap feature; refreshes the preview on consecutive taps
let g:lsp_preview_doubletap = 0

g:lsp_get_vim_completion_item *g:lsp_get_vim_completion_item*
Type: |List|
Default: `[function('lsp#omni#default_get_vim_completion_item')]`
A |List| containing one element of type |Funcref|. This element is a
reference to the function that vim-lsp should use to produce the items in
the completion menu. Changing this variable allows customizing how items
are displayed in the completion menu, or adding custom `user_data` to
items (see |complete-items|).
Note: You can reuse functionality provided by vim-lsp by calling
`lsp#omni#default_get_vim_completion_item` from within your function.
g:lsp_get_supported_capabilities *g:lsp_get_supported_capabilities*
Type: |List|
Default: `[function('lsp#default_get_supported_capabilities')]`
A |List| containing one element of type |Funcref|. This element is a
reference to the function that vim-lsp should use to obtain the supported
LSP capabilities. Changing this variable allows customizing which
capabilities vim-lsp sends to a language server.
Note: You can obtain the default supported capabilities of vim-lsp by
calling `lsp#omni#default_get_supported_capabilities` from within your
function.
g:lsp_peek_alignment *g:lsp_peek_alignment*
Type: |String|
Default: `"center"`
Determines how to align the location of interest for e.g.
|LspPeekDefinition|. Three values are possible: `"top"`, `"center"` and
`"bottom"`, which place the location of interest at the first, middle and
last lines of the preview/popup/floating window, respectively.
g:lsp_preview_max_width *g:lsp_preview_max_width*
Type: |Number|
Default: `-1`
If positive, determines the maximum width of the preview window in
characters. Lines longer than `g:lsp_preview_max_width` will be wrapped to
fit in the preview window. Use a value of `-1` to disable setting a
maximum width.
g:lsp_preview_max_height *g:lsp_preview_max_height*
Type: |Number|
Default: `-1`
If positive, determines the maximum height of the preview window in
characters. Use a value of `-1` to disable setting a maximum height.
g:lsp_signature_help_enabled *g:lsp_signature_help_enabled*
Type: |Number|
Default: `1`
Enable support for signature help. Set to `0` to disable.
Example:
>
let g:lsp_signature_help_enabled = 1
let g:lsp_signature_help_enabled = 0
g:lsp_fold_enabled *g:lsp_fold_enabled*
Type: |Number|
Default: `1`
Determines whether or not folding is enabled globally. Set to `0` to
disable sending requests.
g:lsp_hover_conceal *g:lsp_hover_conceal*
Type: |Boolean|
Default: `1`
If `true` (`1`), |conceallevel| is set to `2` for hover windows. This
means that, for example, asterisks in markdown hovers are hidden, but the
text is still displayed bold. You may want to disable this if the filetype
of the popup has custom conceals which you don't want to use, or if
you're using Vim in a terminal.
To override this setting per server, see |vim-lsp-hover_conceal|.
===============================================================================
FUNCTIONS *vim-lsp-functions*
lsp#enable *vim-lsp-enable*
Enables vim-lsp plugin.
Example:
:call lsp#enable()
lsp#disable *vim-lsp-disable*
Disables vim-lsp plugin.
Example:
:call lsp#disable()
lsp#register_server *vim-lsp-register_server*
Used to register the language server with vim-lsp. This method takes
one parameter which is a vim |dict| and is refered to as |vim-lsp-server-info|
Example:
if (executable('pyls'))
au User lsp_setup call lsp#register_server({
\ 'name': 'name-of-server',
\ 'cmd': {server_info->['server-exectuable']},
\ 'whitelist': ['filetype to whitelist'],
\ 'blacklist': ['filetype to blacklist'],
\ 'config': {},
\ 'workspace_config': {'param': {'enabled': v:true}},
\ })
endif
Note:
* checking for executable is optional but can be used to avoid
unnecessary server registration.
* au User lsp_setup is optional and used to delay registering the
language server after .vimrc has been loaded. It is recommended
to use it if possible.
server_info *vim-lsp-server_info*
The vim |dict| containing information about the server.
{
'name': 'name of the server',
'cmd': {server_info->['server_executable']},
'whitelist': ['filetype'],
'blacklist': ['filetype'],
'config': {},
'workspace_config': {},
}
* name:
required
Name of the language server. Needs to be unique.
* cmd:
required
Function or array which represents command line to start the language
server.
When function, it takes |vim-lsp-server_info| as parameter and returns the
language server executable to run along with the appropriate arguments
when the appropriate filetype is loaded. This function will only be
called when the server has not started.
Return empty array to ignore starting the server.
When array, the first element is the language server executable and
the rest are the appropriate arguments. It is useful when the command line
can be determined statically and |vim-lsp-server_info| is not necessary.
Example:
'cmd': ['pyls']
Function can be complex based on custom requirements.
For example:
- Use binary from local node_modules folder instead of a global
node_modules folder.
- Use different executable based on custom config.
- Return empty array to ignore starting server due to missing
config value required by the server (ex: missing package.json)
- Instead of checking for server executable before calling
register_server it can also be checked here.
Cross-platform compatibility notes:
It is recommended to use &shell with &shellcmdflag when running script
files that can be executed specially on windows where *.bat and *.cmd
files cannot be started without running the shell first. This is common
for exectuables installed by npm for nodejs.
Example:
'cmd': {server_info->
\ [&shell, &shellcmdflag, 'typescript-language-server --stdio']}
* whitelist:
optional
String array of filetypes to run the language server.
Example:
'whitelist': ['javascript', 'typescript']
'*' is treated as any filetype.
* blacklist:
optional
String array of filetypes to run the language server.
Example:
'blacklist': ['javascript', 'typescript']
'*' is treated as any filetype.
whitelist and blacklist can be used together. The following example
says to run the language server for all filetypes except javascript
and typescript. blacklist always takes higher priority over whitelist.
'whitelist': ['*']
'blacklist': ['javascript', 'typescript']
* workspace_config:
optional vim |dict|
Used to pass workspace configuration to the server after
initialization. Configuration settings are language-server specific.
Example:
'workspace_config': {'pyls': {'plugins': \
{'pydocstyle': {'enabled': v:true}}}}
* config:
optional vim |dict|
Used to pass additional custom config.
For example:
'config': { 'prefer_local': 1 }
This can then be used by cmd function.
function! s:myserver_cmd(server_info) abort
let l:config = get(a:server_info, 'config', {})
let l:prefer_local = get(l:config, 'prefer_local', 1)
if (l:prefer_local)
return ['./local-executable']
else
return ['/bin/global-exectuable']
endif
endfunction
'cmd': function('s:myserver_cmd')
The following per-server configuration options are supported by vim-lsp.
* hover_conceal
Type: |Boolean|
Default: |g:lsp_hover_conceal|
This takes precendence over the value of |g:lsp_hover_conceal|, to
allow overriding this setting per server.
Example:
'config': { 'hover_conceal': 1 }
* symbol_kinds
Type: |Dict|
Default: |{}|
This allows overriding the default text mappings for symbol kinds
(e.g., 'module', 'method') per server. Useful for abbreviating or
removing the kind text.
Example:
'config': { 'symbol_kinds': {'26': 'type' } }
* completion_item_kinds
Type: |Dict|
Default: |{}|
This allows overriding the default text mappings for completion item
kinds (e.g., 'module', 'method') per server. Useful for abbreviating
or removing the kind text.
Example:
'config': { 'completion_item_kinds': {'26': 'type' } }
lsp#stop_server *vim-lsp-stop_server*
Used to stop the server.
Example:
call lsp#stop_server('name-of-server')
Note:
* If the server is not running or is not registered it is a noop.
* The server is forcefully stopped without sending shutdown request.
lsp#get_server_status *vim-lsp-get_server_status*
Get the status of a server.
Example:
call lsp#get_server_status('name-of-server')
Returns one of "unknown server", " "exited", "starting", "failed",
"running", "not running".
*vim-lsp-utils-find_nearest_parent_file_directory*
utils#find_nearest_parent_file_directory
Find the nearest parent directory which contains the specific files or
diretories. The method has two parameters. The first is the path where
searching starts. The second is the files or directories names which
you want to find. The return value is the directory path which is found
the most times.
This method is mainly used to generate 'root_uri' when registering server.
Example:
if executable('ccls')
au User lsp_setup call lsp#register_server({
\ 'name': 'ccls',
\ 'cmd': {server_info->['ccls']},
\ 'root_uri':{server_info->lsp#utils#path_to_uri(
\ lsp#utils#find_nearest_parent_file_directory(
\ lsp#utils#get_buffer_path(),
\ ['.ccls', 'compile_commands.json', '.git/']
\ ))},
\ 'initialization_options': {},
\ 'whitelist': ['c', 'cpp', 'objc', 'objcpp', 'cc'],
\ })
endif
Note:
* The second parameter can be a |String| or a string |List|.
* For the second parameter, the string ends with '/' or '\' will
be regarded as a directory name, otherwise as a file name.
* If there is not directory with the specific files or diretories
found, the method will return an empty string.
lsp#get_buffer_diagnostics_counts *vim-lsp-get_buffer_diagnostics_counts*
Get dict with diagnostic counts for current buffer. Useful e.g. for display
in status line.
Returns dictionary with keys "error", "warning", "information", "hint".
lsp#get_buffer_first_error_line *vim-lsp-get_buffer_first_error_line*
Get line number of first error in current buffer.
Returns |Number| or |v:null| if there are no errors.
===============================================================================

* To control the default focus of |preview-window| for |LspHover|
configure |g:lsp_preview_keep_focus|.
* If using neovim with nvim_win_open() available, |g:lsp_preview_float| can be
set to enable a floating preview at the cursor which is closed automatically
on cursormove if not focused and can be closed with <esc> if focused.

===============================================================================
Autocommands *vim-lsp-autocommands*
lsp_complete_done *lsp_complete_done*
This autocommand is run after Insert mode completion is done, similar to
|CompleteDone|. However, the difference is that |lsp_complete_done| is run
only after vim-lsp has finished executing its internal |CompleteDone|
autocommands (e.g. applying text edits). It is thus ideal to use for snippet
expansion, or custom post processing of completed items. Just like
|CompleteDone|, the Vim variable |v:completed_item| contains information about
the completed item. It is guaranteed that vim-lsp does not change the content
of this variable during its |CompleteDone| autocommands.
===============================================================================
Mappings *vim-lsp-mappings*
To map keys to the feature of vim-lsp, use <plug> mappings:
>
autocmd FileType python,go nmap gd <plug>(lsp-definition)
<
Available plug mappings are following:
(lsp-code-action)
(lsp-declaration)
(lsp-peek-declaration)
(lsp-definition)
(lsp-peek-definition)
(lsp-document-symbol)
(lsp-document-diagnostics)
(lsp-hover)
(lsp-next-error)
(lsp-next-reference)
(lsp-preview-close)
(lsp-preview-focus)
(lsp-previous-error)
(lsp-previous-reference)
(lsp-references)
(lsp-rename)
(lsp-workspace-symbol)
(lsp-document-format)
(lsp-document-format)
(lsp-implementation)
(lsp-peek-implementation)
(lsp-type-definition)
(lsp-peek-type-definition)
(lsp-status)
See also |vim-lsp-commands|
<plug>(lsp-preview-close) *<plug>(lsp-preview-close)*
Closes an opened preview window
<plug>(lsp-preview-focus) *<plug>(lsp-preview-focus)*
Transfers focus to an opened preview window or back to the previous window if
focus is already on the preview window.
===============================================================================
Autocomplete *vim-lsp-autocomplete*
omnifunc *vim-lsp-omnifunc*
vim-lsp by default only provides basic omnifunc support for autocomplete.
Completion can be made asynchronous by setting g:lsp_async_completion.
Note that this may cause unexpected behavior in some plugins such as MUcomplete.
If you would like to have more advanced features please use asyncomplete.vim as
described below.
Example:
autocmd FileType typescript setlocal omnifunc=lsp#complete
asyncomplete.vim *vim-lsp-asyncomplete*
asyncomplete.vim is a async auto complete plugin for vim8 and neovim written
in pure vim script. https://github.com/prabirshrestha/asyncomplete.vim
Example:
Plug 'prabirshrestha/async.vim'
Plug 'prabirshrestha/vim-lsp'
Plug 'prabirshrestha/asyncomplete.vim'
Plug 'prabirshrestha/asyncomplete-lsp.vim'
For additional configuration refer to asyncomplete.vim docs.
===============================================================================
Snippets *vim-lsp-snippets*
To integrate snippets in vim-lsp, you will first have to install a third-party
snippet plugin, and a plugin that integrates it in vim-lsp. At the moment,
you have two options:
1. UltiSnips and vim-lsp-ultisnips
https://github.com/SirVer/ultisnips
https://github.com/thomasfaingnaert/vim-lsp-ultisnips
2. neosnippet.vim and vim-lsp-neosnippet
https://github.com/Shougo/neosnippet.vim
https://github.com/thomasfaingnaert/vim-lsp-neosnippet
Refer to the readme and docs of vim-lsp-ultisnips and vim-lsp-neosnippet for
more information and configuration options.
===============================================================================
Folding *vim-lsp-folding*
You can also let the language server handle folding for you. To enable this
feature, you will have to set |'foldmethod'|, |'foldexpr'| and |'foldtext'| (the
latter is optional) correctly:
set foldmethod=expr
\ foldexpr=lsp#ui#vim#folding#foldexpr()
\ foldtext=lsp#ui#vim#folding#foldtext()
Also, make sure you have not disabled folding globally, see
|g:lsp_fold_enabled|.
You may want to enable this only for certain filetypes, e.g. for Javascript
only:
augroup lsp_folding
autocmd!
autocmd FileType javascript setlocal
\ foldmethod=expr
\ foldexpr=lsp#ui#vim#folding#foldexpr()
\ foldtext=lsp#ui#vim#folding#foldtext()
augroup end
To display open and closed folds at the side of the window, see
|'foldcolumn'|.
If you want to remove the dashes at the end of the folds, you can change
the fold item of |'fillchars'|.
