INTRODUCTION *coc-introduction*
Coc.nvim enhances your (Neo)Vim to match the user experience provided by
VSCode through a rich plugin (or extension) ecosystem and support for Language
Server Protocol.
Some of its key features include:~
- APIs compatible with both Vim8 and Neovim.
- Loading VSCode-like extensions.
- Configuring coc.nvim and its extensions with a JSON configuration file.
- Configuring Language Servers implemented according to Language Server
Protocol (LSP).
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 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 `coc-settings.json` file. You can
open it through |:CocConfig|. This will open (or create) a global settings
files in folder returned by |coc#util#get_config_home()|
To create a local configuration project for a specific workspace, use
|:CocLocalConfig|: this will create `.vim/coc-settings.json` in the current
workspace folder.
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/you/prefer'
When creating a local configuration file, it's possible to use
|b:coc_root_patterns| for resolve the root directory from the filepath of
opened buffer.
Since the configuration files are all in JSON format, it's suggested to enable
JSON completion and validation by install the `coc-json` extension: >
:CocInstall coc-json
<

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.
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.
==============================================================================
INTERFACE *coc-interface*
------------------------------------------------------------------------------
Key mappings *coc-key-mappings*
Unlike some vim plugins, coc.nvim doesn't create user global key-mappings by
default. However, 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.

<
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')|, normally you
would like to use a command like: >
command! -nargs=0 Format :call CocAction('format')

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

Semantic tokens highlighting is disabled by default, you can enable it by use
configuration "semanticTokens.filetypes", see |coc-config-semanticTokens| for
details.
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 command, for example:
>
:hi link CocSemDeclarationVariable MoreMsg
<
- Refresh semantic highlight of current buffer by:
>
:CocCommand semanticTokens.refreshCurrent
<
Use `:CocCommand semanticTokens.checkCurrent` to check semantic highlight
information with current buffer.
*CocSem*
Semantic highlight groups are starts with 'CocSem' which links to related
|nvim-treesitter| highlight groups when possible and fallback to builtin
highlight groups, use variable |g:coc_default_semantic_highlight_groups| to
disable creation of these highlight groups.
Currently only semantic tokens types and `deprecated` modifier have default
highlight groups. You need create highlight groups for highlight other
modifiers and/or specific modifier with type, for example:
>
" Add highlights for defaultLibrary modifier
hi link CocSemDefaultLibrary TSOtherDefaultLibrary
hi link CocSemDefaultLibraryClass TSTypeDefaultLibrary
hi link CocSemDefaultLibraryInterface TSTypeDefaultLibrary
hi link CocSemDefaultLibraryEnum TSTypeDefaultLibrary
hi link CocSemDefaultLibraryType TSTypeDefaultLibrary
hi link CocSemDefaultLibraryNamespace TSTypeDefaultLibrary
" Add highlights for declaration modifier
hi link CocSemDeclaration TSOtherDeclaration
hi link CocSemDeclarationClass TSTypeDeclaration
hi link CocSemDeclarationInterface TSTypeDeclaration
hi link CocSemDeclarationEnum TSTypeDeclaration
hi link CocSemDeclarationType TSTypeDeclaration
hi link CocSemDeclarationNamespace TSTypeDeclaration
<
The modifier highlight groups have higher priority.

NOTIFICATION SUPPORT *coc-notification*
Notification windows are shown from bottom right of the screen. Notifications
behavior like notifications on VSCode.
Notifications are created by javascript APIs: `window.showErrorMessage()`,
`window.showWarningMessage()`, `window.showInformationMessage()`,
`window.showNotification()` and `window.withProgress()`.
Possible kind of notifications: 'error', 'warning', 'info' and 'progress'.
Message notifications (not progress) requires
|coc-preferences-enableMessageDialog| to be `true`. Message notifications
without actions would be automatically closed after milliseconds specified by
|coc-config-notification-timeout|.
Features:
- Animated position and 'winblend' on show and hide.
- Reposition current tab notification windows when notification dismissed.
- Notification with same options will be replaced to avoid duplicated windows.
- Percent and message update for progress notification.
- Click the button (neovim only) or use |coc#notify#do_action()| to invoke
actions.
- Click the window would cancel auto close (on neovim and focusable is true).
- For customize icons, see |g:coc_notify|.
- For customize highlights, see |CocNotification|.
- For customize other behaviors, see |coc-config-notification|.
- For available user actions (ex: "close_all", "do_action" "show_sources"), see
|coc#notify|.
Note notification feature requires neovim >= 0.4.0 or vim >= 8.2.0750 to work.
