INTRODUCTION *coc-introduction*
Coc.nvim enhances your (Neo)Vim to match the user experience provided by
VSCode through a rich extension ecosystem and implemented features of Language
Server Protocol (3.16 for now).
Some of its key features include:~
- APIs compatible with both Vim8 and Neovim.
- Loading VSCode-like extensions.
- Configuring coc.nvim and its extensions with JSON configuration
|coc-configuration|.
- Configuring Language Servers that using Language Server Protocol (LSP)
|coc-config-languageserver|.
It is designed for best possible integration with other Vim plugins.
Note: This plugin doesn't come with support for any specific language. You
will need to install a coc.nvim extension or set up the language server by
configuration.
Note: This plugin doesn't change any of your existing key-mappings. You will
need to create key-mappings by yourself, see README.md for examples.
Note: Automatic completion plugins can't play nicely together, you can disable
automatic completion of coc.nvim through `"suggest.autoTrigger": "none"` (or
`"suggest.autoTrigger": "trigger"`) in your configuration file.
==============================================================================
REQUIREMENTS *coc-requirements*
Neovim >= 0.3.2 or Vim >= 8.0.1453, for best experience, use neovim >= 0.4.0
or vim >= 8.2.0750.
NodeJS https://nodejs.org/ >= 12.12.0.
Yarn https://yarnpkg.com/ required to build coc.nvim from typescript source
code.
==============================================================================
INSTALLATION *coc-installation*
If you're using [vim-plug](https://github.com/junegunn/vim-plug), add this to
your `init.vim` or `.vimrc`: >
Plug 'neoclide/coc.nvim', {'branch': 'release'}
<
And run: >
:PlugInstall
For other plugin managers, make sure to use code from the release branch.
You can also use Vim's native package management like: >
#!/bin/sh
# for vim8
mkdir -p ~/.vim/pack/coc/start
cd ~/.vim/pack/coc/start
curl --fail -L https://github.com/neoclide/coc.nvim/archive/release.tar.gz|tar xzfv -
# for neovim
mkdir -p ~/.local/share/nvim/site/pack/coc/start
cd ~/.local/share/nvim/site/pack/coc/start
curl --fail -L https://github.com/neoclide/coc.nvim/archive/release.tar.gz|tar xzfv -
==============================================================================
CONFIGURATION *coc-configuration*
The configuration of coc.nvim is stored in file `coc-settings.json`.
Command |:CocConfig| will open (create when necessary) a user settings
file in the folder returned by |coc#util#get_config_home()|
To create a local configuration file for a specific workspace, use
|:CocLocalConfig|.
The global configuration file can be created in another directory by setting
`g:coc_config_home` in your `.vimrc` or `init.vim`: >
let g:coc_config_home = '/path/to/folder'
The configuration files are all in JSON format, it's recommended to
enable JSON completion and validation by install the `coc-json` extension: >
:CocInstall coc-json
<
The user configuration can also be changed by |coc#config()|.
Configurations are composed with builtin configurations and configurations
contributed by coc extensions, see |coc-config| for builtin configurations.
==============================================================================
LSP FEATURES *coc-lsp*
All features (except for telemetry) of LSP 3.16 are supported, checkout
the specification at
https://microsoft.github.io/language-server-protocol/specifications/specification-3-16/
Use `:CocCommand document.checkBuffer` to check exists providers used by
current buffer. Or use API |CocHasProvider()|.
For historic reason, some features just works, but some are not.
Features automatically work by default:~
- Trigger completion |coc-completion|.
- Diagnostics refresh |coc-diagnostics|.
- Trigger signature help |coc-signature|.
- Inlay hints (only works with some coc extensions, but not
|coc-config-languageserver| yet).
Note the features could be disabled by |coc-configuration| and some vim
variables.
Features require enabled by configuration:~
- Semantic highlights |coc-semantic-highlights|.
- Document color highlights |coc-document-color|.
- Code lens, enabled by |coc-config-codeLens-enable|.
- Linked editing, enabled by |coc-preferences-enableLinkedEditing|.
- Format on type, enabled by |coc-preferences-formatOnType|
- Format on save, enabled by |coc-preferences-formatOnSaveFiletypes|.
Features requested by user:~
- Invoke code action |coc-code-actions|.
- Show call hierarchy tree |coc-callHierarchy|.
- Format, range format and on type format |coc-format|.
- Highlight same symbol ranges |coc-document-highlights|.
- Outline of document symbols |coc-outline| and |coc-list-symbols|.
- Show hover message |CocAction('doHover')| and |CocAction('definitionHover')|.
- Rename current symbol |CocAction('rename')|.
- Jump to definition locations |CocAction('jumpDefinition')|.
- Jump to declaration locations |CocAction('jumpDeclaration')|.
- Jump to implementation locations |CocAction('jumpImplementation')|.
- Jump to type definition locations |CocAction('jumpTypeDefinition')|.
- Jump to references |CocAction('jumpReferences')| and |CocAction('jumpUsed')|.
- Open link under cursor |CocAction('openlink')|.
- Range selection |CocAction('rangeSelect').|
- Create folds |CocAction('fold')|.
For convenient, some actions have associated |coc-key-mappings| provided.
Features triggered by languageserver or extension:~
- Show message notification.
- Show message request.
- Log message (use `:CocCommand workspace.showOutput` to show output).
- Show document request.
- Work done progress.
To make coc.nvim provide LSP features for your languages, checkout
https://github.com/neoclide/coc.nvim/wiki/Language-servers
To debug issues with languageserver, checkout
https://github.com/neoclide/coc.nvim/wiki/Debug-language-server
==============================================================================
DOCUMENT *coc-document*
A document is created on buffer create, and disposed on buffer unload.
Attached document:~
*coc-document-attached*
An attached document means coc.nvim synchronize the lines of vim's buffer with
associated document automatically.
Only attached documents are synchronized with language servers and therefore
LSP features could be provided for the attached buffer.
The buffer may not be attached by following reasons:
- The 'buftype' is neither <empty> nor 'acwrite'.
- Buffer variable |b:coc_enabled| should is `1`.
- Byte length of buffer exceed |coc-preferences-maxFileSize|.
- Buffer is used for command line window.
Use |CocAction('ensureDocument')| or `:CocCommand document.checkBuffer` to
check attached state of current buffer.
Filetype map:~
*coc-document-filetype*
Some filetypes are mapped to others to match the languageId used by VSCode,
including:
- javascript.jsx -> javascriptreact
- typescript.jsx -> typescriptreact
- typescript.tsx -> typescriptreact
- tex -> latex
Use |g:coc_filetype_map| to create additional filetype maps.
Use `:CocCommand document.echoFiletype` to echo mapped filetype of current
document.
Note make sure use mapped filetypes for configurations that expect filetypes.
==============================================================================
COMPLETION *coc-completion*
Default behavior of coc.nvim's completion:
- Completion is automatically triggered.
- 'completeopt' is temporarily changed to `noinsert,menuone`.
- Snippet complete item would only be expanded after confirm completion.
Use configurations |coc-config-suggest| to change behavior of completion.
Related variables:~
- |b:coc_suggest_disable|
- |b:coc_disabled_sources|
- |b:coc_suggest_blacklist|
- |b:coc_additional_keywords|
Related APIs:~
- |coc#start()|
- |coc#refresh()|
- |coc#_select_confirm()|
Tips:~
- 'completeopt' used by coc.nvim default to `noselect,menuone`.
- Your 'completeopt' option would be changed and restored during completion,
so you can still use `menu,preview` for Vim's built in completion.
- Snippet expand and additional edit feature of LSP requires confirm
completion by <C-y> to work.
------------------------------------------------------------------------------
Example completion key-mappings:~
Map <tab> to trigger completion and navigate to the next item: >
function! s:check_back_space() abort
let col = col('.') - 1
return !col || getline('.')[col - 1] =~ '\s'
endfunction
inoremap <silent><expr> <TAB>
\ pumvisible() ? "\<C-n>" :
\ <SID>check_back_space() ? "\<TAB>" :
\ coc#refresh()
Map <c-space> to trigger completion: >
inoremap <silent><expr> <c-space> coc#refresh()
<
<CR> to confirm completion, use: >
inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<CR>"
<
To make <CR> auto-select the first completion item and notify coc.nvim to
format on enter, use: >
inoremap <silent><expr> <cr> pumvisible() ? coc#_select_confirm()
\: "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"
Map <tab> for trigger completion, completion confirm, snippet expand and jump
like VSCode. >
inoremap <silent><expr> <TAB>
\ pumvisible() ? coc#_select_confirm() :
\ coc#expandableOrJumpable() ?
\ "\<C-r>=coc#rpc#request('doKeymap', ['snippets-expand-jump',''])\<CR>" :
\ <SID>check_back_space() ? "\<TAB>" :
\ coc#refresh()
function! s:check_back_space() abort
let col = col('.') - 1
return !col || getline('.')[col - 1] =~# '\s'
endfunction
let g:coc_snippet_next = '<tab>'
<
Note: the `coc-snippets` extension is required for this to work.
==============================================================================
DIAGNOSTICS SUPPORT *coc-diagnostics*
Diagnostics of coc.nvim are automatically refreshed to UI by default, checkout
|coc-config-diagnostic| for available configurations.
Note most language servers only send diagnostics for opened buffers for
performance reason, some lint tools could provide diagnostics for all files in
workspace.
Note pull diagnostics feature is added in LSP 3.17, which is not available
yet.
Changes on diagnostics refresh~
- Add highlights for diagnostic ranges and virtual text (when enabled on
neovim with virtual text support), see |coc-highlights-diagnostics|.
- Add diagnostic signs to 'signcolumn', use `set signcolumn=yes` to avoid
unnecessary UI refresh.
- Update variable |b:coc_diagnostic_info|.
- Refresh related |location-list| which was opened by |:CocDiagnostics|.
Diagnostics are not refreshed when buffer is hidden, and refresh on insert
mode is disabled by default.
Diagnostics highlights:~
See |coc-highlights-diagnostics|.
Enable and disable diagnostics~
Use |coc-config-diagnostic-enable| to toggle diagnostics feature.
Use |CocAction('diagnosticToggle')| for enable/disable diagnostics of current
buffer.
Show diagnostic messages~
Diagnostic messages would be automatically shown/hide when the diagnostics
under cursor position changed (use float window/popup when possible) by
default.
To manually refresh diagnostics messages, use |<Plug>(coc-diagnostic-info)|
and |CocAction('diagnosticPreview')|.
Jump between diagnostics~
Use key-mappings:
|<Plug>(coc-diagnostic-next)| jump to next diagnostic.
|<Plug>(coc-diagnostic-prev)| jump to previous diagnostic.
|<Plug>(coc-diagnostic-next-error)| jump to next error.
|<Plug>(coc-diagnostic-prev-error)| jump to previous error.
Check all diagnostics~
Use |coc-list-diagnostics| to open |CocList| with all diagnostics.
Use API |CocAction('diagnosticList')| to get list of all diagnostics.
==============================================================================
SIGNATURE HELP *coc-signature*
Signature help of function is automatically triggered by default(when user
type trigger characters defined by the provider), which will use float
window/popup to show the signature messages when possible.
Use |CocAction('showSignatureHelp')| to trigger signature help manually.
Note error will not be thrown when provider not exists or nothing returned
from languageserver, use `:CocCommand document.checkBuffer` to check provider
state of current buffer.
Use |coc-config-signature| to change default signature help behavior.
==============================================================================
FORMAT *coc-format*
There're various ways to format document.
Format full document:~
Use |CocAction('format')|, you can create a command like: >
command! -nargs=0 Format :call CocActionAsync('format')
<
to format current buffer.
Format on type:~
Enable format when insert specific characters by configurations:
- |coc-preferences-formatOnType|
- |coc-preferences-formatOnTypeFiletypes|
requires `onTypeEdit` provider |CocHasProvider|.
Format selected code:~
Use 'formatexpr' for specific filetypes: >
autocmd FileType typescript,json setl formatexpr=CocAction('formatSelected')
So that |gq| could works for format range of lines.
>
Setup visual mode and operator key-mappings: >
xmap <leader>f <Plug>(coc-format-selected)
nmap <leader>f <Plug>(coc-format-selected)
<
Format on save:~
Use configuration |coc-preferences-formatOnSaveFiletypes|.
Or create |BufWritePre| autocmd like: >
autocmd BufWritePre * call CocAction('format')
<
Note avoid use |CocActionAsync| with |BufWritePre|.
==============================================================================
CODE ACTION *coc-code-actions*
Code actions are used for make some specific code changes.
There're different kinds of code actions:
- `quickfix` used for fix diagnostic(s).
- `refactor` used for code refactor.
- `source` code actions apply to the entire file.
- `organizeImport` organize import statements of current document.
Invoke code action~
To fix diagnostic at current line, use |<plug>(coc-fix-current)|.
Key-mappings for choose code action:~
- |<plug>(coc-codeaction-cursor)|
- |<plug>(coc-codeaction-line)|
- |<plug>(coc-codeaction)|
- |<plug>(coc-codeaction-selected)|
|coc-dialog-menu| would be shown for pick specific code action.
To invoke organize import action, use command like:
>
command! -nargs=0 OR :call CocAction('runCommand',
\ 'editor.action.organizeImport')
Related APIs~
- |CocAction('codeActions')|
- |CocAction('organizeImport')|
- |CocAction('fixAll')|
- |CocAction('quickfixes')|
- |CocAction('doCodeAction')|
- |CocAction('doQuickfix')|
- |CocAction('codeActionRange')|
==============================================================================
DOCUMENT HIGHLIGHTS *coc-document-highlights*
Document highlights is used for highlight same symbols of current document
under cusor.
To enable highlight on CursorHold, create an autocmd like this: >
autocmd CursorHold * silent call CocActionAsync('highlight')
<
Checkout |coc-highlights-document| for related highlight groups.
Note error will not be thrown when provider not exists or nothing returned
from languageserver with |CocAction('highlight')|
Install `coc-highlight` extension if you want to highlight same words under
cursor without languageserver support.
To jump between previous/next symbol position, use
`:CocCommand document.jumpToPrevSymbol` and
`:CocCommand document.jumpToNextSymbol`
==============================================================================
DOCUMENT COLOR *coc-document-color*
Document colors added color highlights to your documents. To enable document
color highlights, use ||coc-config-colors-filetypes||.
Install `coc-highlights` to provide document color highlights for all
filetypes.
To pick a color from system color picker, use |CocAction('pickColor')| or
choose `editor.action.pickColor` from |:CocCommand|.
Note: may not work on your system.
To change color presentation, use |CocAction('colorPresentation')| or choose
`editor.action.colorPresentation` from |:CocCommand|.
==============================================================================
SNIPPETS SUPPORT *coc-snippets*
Snippets engine of coc.nvim support both VSCode snippets and ultisnips
snippets format.
The complete item with snippet format has label ends with `~` by default.
Select the complete item and confirm the completion by <C-y> to expand the
snippet.
A snippet session would be deactivated under the following conditions:
- |InsertEnter| triggered outside snippet.
- Jump to final placeholder.
- Content change detected after snippet.
- Content changed in a snippet outside placeholder (except for deletion of
plain text).
To load and expand custom snippets, install `coc-snippets` extension is
recommended.
Related configurations:
- |g:coc_snippet_prev|
- |g:coc_snippet_next|
- |coc-config-suggest-snippetIndicator|
- |coc-config-suggest-preferCompleteThanJumpPlaceholder|
- |coc-preferences-snippetStatusText|
- |coc-preferences-snippetHighlight|
Related functions:
- |coc#snippet#next()|
- |coc#snippet#prev()|
- |coc#expandable()|
- |coc#jumpable()|
- |coc#expandableOrJumpable()|
Related variables: |b:coc_snippet_active|
Related highlights: |CocSnippetVisual|
Related autocmds: |CocJumpPlaceholder|
==============================================================================
WROKSPACE SUPPORT *coc-workspace*
Workspace folders~
Unlike VSCode, workspace folders are resolved from filepath after buffer load.
A list of file/folder names is used for resolve workspace folder, the patterns
could comes from:
- |b:coc_root_patterns|
- `rootPatterns` field of configured language server.
- `rootPatterns` contributions from coc extensions.
- |coc-preferences-rootPatterns|
Workspace folder is resolved from cwd of vim first and then from top directory
to the parent directory of current filepath, when workspace folder not
resolved, current working directory is used if it's parent folder of current
buffer. Configurations are provided to change the default behavior:
- |coc-config-workspace-ignoredFiletypes|
- |coc-config-workspace-ignoredFolders|
- |coc-config-workspace-bottomUpFiletypes|
- |coc-config-workspace-workspaceFolderCheckCwd|
- |coc-config-workspace-workspaceFolderFallbackCwd|
Note for performance reason, user's home directory would never considered as
workspace folder, which also means the languageserver that requires workspace
folder may not work when you start vim from home directory.
To preserve workspace folders across vim session, |g:WorkspaceFolders| is
provided.
To manage current workspace folders, use |coc-list-folders|
To get related root patterns of current buffer, use |coc#util#root_patterns()|
Use `:CocCommand workspace.workspaceFolders` to echo current workspaceFolders.
Workspace edit~
Workspace edit is used to apply changes for multiple buffers(and files), the
edit could includes document edits and file operations (including file create,
file/directory delete and file/directory rename).
When the edit failed to apply, coc.nvim will revert the changes (including
document edits and file operations) that previous made.
Files not loaded would be loaded by `tab drop` command, configured by
|coc-config-workspace-openResourceCommand|.
To undo and redo workspace edit just applied, use command
`:CocCommand workspace.undo` and `:CocCommand workspace.redo`
To inspect previous workspace edit, use command
`:CocCommand workspace.inspectEdit`, in opened buffer, use <CR> for jump to
change position under cursor.
==============================================================================
CURSORS SUPPORT *coc-cursors*
Multiple cursors supported is added to allow edit multiple locations at once.
Cursors session could be started by following ways:
- Use command `:CocCommand document.renameCurrentWord` to rename variable
under cursor.
- Use |<plug>(coc-refactor)| to open refactor buffer.
- Use |:CocSearch| to open searched locations.
- Use cursors related key-mappings to add text range, including
|<plug>(coc-cursors-operator)|, |<Plug>(coc-cursors-word)|,
|<Plug>(coc-cursors-position)| and |<plug>(coc-cursors-range)|
- Ranges added by command `editor.action.addRanges` from coc extensions.
Default key-mappings when cursors activated:
- <esc> cancel cursors session.
- <C-n> jump to next cursors range.
- <C-p> jump to previous cursors range.
Use |coc-config-cursors| to change cursors related key-mappings.
Use highlight group |CocCursorRange| to change default range highlight.
Use |b:coc_cursors_activated| to check if cursors session is enabled.
==============================================================================
SYMBOLS OUTLINE *coc-outline*
Outline is a split window with current document symbols rendered as
|coc-tree|.
To show and hide outline of current window, use |CocAction('showOutline')| and
|CocAction('hideOutline')|.
Outline view has Window variable `cocViewId` set to `OUTLINE`.
Following outline features are supported:
- Start fuzzy filter by |coc-config-tree-key-activeFilter|.
- Automatic update after document change.
- Automatic reload when buffer in current window changed.
- Automatic follow cursor position by default.
- Different filter modes that can be changed on the fly
|coc-config-outline-switchSortKey|.
Note: outline would try to reload document symbols after 500ms when provider
not registered, which avoid the necessary to check provider existence.
Checkout |coc-config-tree| and |coc-config-outline| for available
configurations.
Checkout |CocTree| and |CocSymbol| for customize highlights.
Use configuration `"suggest.completionItemKindLabels"` for custom icons.
To show outline for each tab automatically, use |autocmd|:
>
autocmd VimEnter,Tabnew *
\ if empty(&buftype) | call CocActionAsync('showOutline', 1) | endif
<
To close outline when it's the last window automatically, use
|autocmd| like:
>
autocmd BufEnter * call CheckOutline()
function! CheckOutline() abort
if &filetype ==# 'coctree' && winnr('$') == 1
if tabpagenr('$') != 1
close
else
bdelete
endif
endif
endfunction
<
Create a key-mapping to toggle outline, like:
>
nnoremap <silent><nowait> <space>o :call ToggleOutline()<CR>
function! ToggleOutline() abort
let winid = coc#window#find('cocViewId', 'OUTLINE')
if winid == -1
call CocActionAsync('showOutline', 1)
else
call coc#window#close(winid)
endif
endfunction
<
==============================================================================
CALL HIERARCHY *coc-callHierarchy*
A call hierarchy is a splited |coc-tree| with locations for incoming or
outgoing calls of current function.
Call hierarchy window is opend by |CocAction('showIncomingCalls')| and
|CocAction('showOutgoingCalls')|.
Call hierarchy is configured by |CocSymbol|, |coc-config-callHierarchy| and
|coc-config-tree|.
Related ranges are highlighted with |CocSelectedRange| highlight group in
opend buffer.
|coc-dialog-menu| could be invoked by |coc-config-tree-key-actions|.
Available actions:
- Dismiss.
- Open in new tab.
- Show Incoming Calls.
- Show Outgoing Calls.
Use <CR> in call hierarchy tree to open location in original window.
==============================================================================
SEMANTIC HIGHLIGHTS *coc-semantic-highlights*
Semantic tokens are used to add additional color information to a file that
depends on language specific symbol information.
Use |coc-config-semanticTokens-filetypes| to enable semantic tokens highlights.
Use `:CocCommand semanticTokens.checkCurrent` to check semantic highlight
information with current buffer.
To create custom highlights for symbol under cursor, follow these steps:
- Inspect semantic token by
>
:CocCommand semanticTokens.inspect
<
to check token type and token modifiers with current symbol.
- Create new highlight group by |highlight|, for example:
>
:hi link CocSemDeclarationVariable MoreMsg
<
- Refresh semantic highlight of current buffer by:
>
:CocCommand semanticTokens.refreshCurrent
<
See |CocSem| to customize semantic token highlight groups.
See |coc-config-semanticTokens| for related configurations.
==============================================================================
INTERFACE *coc-interface*
------------------------------------------------------------------------------
Key mappings *coc-key-mappings*
There're some cases that local key-mappings are enabled for current buffer.
Snippet jump key-mappings when snippet is activated:
|g:coc_snippet_prev| and |g:coc_snippet_next|.
Cursor jump and cancel key-mappings when cursors is activated
|coc-config-cursors|.
Dialog key-mappings for confirm and cancel dialog window
|coc-config-dialog|.
Key-mappings for |CocList| buffer: |coc-list-mappings|.
Note: Use |:verbose| command to check key-mappings that taking effect.
Note: Use 'noremap' with <Plug> will make the key-mapping not work at all.
Note: <Plug> key-mappings are provided for convenient, use |CocActionAsync()| or
|CocAction()| for more options.
Normal mode key-mappings:~
*<plug>(coc-diagnostic-info)* Show diagnostic message of current position by
invoke |CocAction('diagnosticInfo')|
*<plug>(coc-diagnostic-next)* Jump to next diagnostic position.

when used in normal mode, the selection works on the motion object.
For example: >
vmap <leader>p <Plug>(coc-format-selected)
nmap <leader>p <Plug>(coc-format-selected)
<
makes `<leader>p` format the visually selected range, and you can use
`<leader>pap` to format a paragraph.
*<plug>(coc-format)* Format the whole buffer by invoke |CocAction('format')|
*<plug>(coc-rename)* Rename symbol under cursor to a new word by invoke
|CocAction('rename')|

Note: the search is performed on your files, so normally you should
save your buffers before invoke this command.
Common arguments for ripgrep:~
`-e` `--regexp`: treat search pattern as regexp.
`-F` `--fixed-strings`: treat search pattern as fixed string.
`-L` `--follow`: follow symbolic links while traversing directories.
`-g` `--glob` {GLOB}: Include or exclude files and directories for
searching that match the given glob.

`.ignore` are respected
Escape arguments:~
|<f-args>| is used to convert command line arguments to arguments of
rg, which means you have to escape space for single argument. For
example, if you want to search `import { Neovim` , you have to use:
>
:CocSearch import\ \{\ Neovim
<
The escape for `{` is required because rg use regexp be default, or:
>
:CocSearch -F import\ {\ Neovim
<
for strict match.

Supported key-mappings:
<C-a> - move cursor to first col.
<C-e> - move cursor to last col.
<esc> - cancel input, null is received by callback.
