INTRODUCTION						**coc-introduction**

Coc.nvim enhances your (Neo)Vim to match the user experience provided by
VSCode through a rich extension ecosystem and implemented the client features
specified by Language Server Protocol (3.17 for now), see |coc-lsp|.

Some features (like completion and inline completion) automatically works by
default, all of them can be disabled by |coc-configuration|.

# Some key features: ~

  • Typescript APIs compatible with both Vim8 and Neovim.
  • Loading VSCode-like extensions |coc-api-extension|.
  • 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: coc.nvim doesn't come with support for any specific language. You
will need to install coc.nvim extensions |coc-extensions| or set up the
language server by use |coc-config-languageserver|.

Note: multiple language servers for same document is allowed, but you should
avoid configure same language server that already used by coc.nvim extension.

Note: automatic completion plugins can't play nicely together, you can disable
automatic completion of coc.nvim by use `"suggest.autoTrigger": "none"` (or
`"suggest.autoTrigger": "trigger"`) in your |coc-configuration|.

==============================================================================
REQUIREMENTS						**coc-requirements**

Neovim >= 0.8.0 or Vim >= 9.0.0483.

NodeJS https://nodejs.org/ >= 16.18.0.

For neovim user, use command |:checkhealth| to check issue with current
environment.

==============================================================================
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 the release branch (unless you
need to build from typescript source code).

To use Vim's native |packages| on Linux or macOS, use script 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 -
# vim -c 'helptags ~/.vim/pack/coc/start/doc|q'

  # 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 -
# nvim -c 'helptags ~/.local/share/nvim/site/pack/coc/start|q'

when using source code of coc.nvim, you'll have to run `npm install` in project
root of coc.nvim.

==============================================================================
File system watch					**coc-filesystemwatch**

Watchman https://facebook.github.io/watchman/ is used by coc.nvim to provide
file change detection to extensions and languageservers.  The watchman command
is detected from your `$PATH`, the feature will silently fail when watchman
can't work.

Watchman automatically watch |coc-workspace-folders| for file events by
default.

Use command: >
```
:CocCommand workspace.showOutput watchman
```
<
to open output channel of watchman.

Use configuration |coc-config-fileSystemWatch| to change behavior of file
system watch.

Note: The default filesystem watch limit can be easily exceeded for many
projects, checkout
https://facebook.github.io/watchman/docs/install#system-specific-preparation

==============================================================================
LANGUAGESERVER 						**coc-languageserver**

Language servers are services which provide LSP features, the servers are
provided by |coc-extensions| or |coc-config-languageserver|.

To get language server for your language, see:
https://github.com/neoclide/coc.nvim/wiki/Language-servers

To debug language server, see:
https://github.com/neoclide/coc.nvim/wiki/Debug-language-server

==============================================================================
EXTENSIONS						**coc-extensions**

Compare to |coc-config-languageserver| extensions are more powerful since they
could contribute json schemes, commands, and use middleware methods of
languageserver to provide better results.  Extensions could provide more
features by make use of NodeJS and coc.nvim's API.

```
						*coc-extensions-folder*
```
Extensions are loaded from `"extensions"` folder inside
|coc#util#get_data_home()| and folders in 'runtimepath' when detected.

Use `let $COC_NO_PLUGINS = '1'` in vimrc to disable the load of extensions.

See |coc-api-extension| for the guide to create coc.nvim extension.

# Install extensions from git (not recommended): ~

  • Download the source code.
  • In project root, install dependencies and compile the code by `npm install`
    (needed by most coc extensions).
  • Add the project root to vim's runtimepath by `set runtimepath^=/path/to/project`

Plugin manager like [vim-plug] can be used as well.

Note: use coc.nvim extensions from source code requires install dependencies,
which may take huge disk usage.

```
						*coc-extensions-npm*
# Install global extensions from npm (recommended): ~
```

Use |:CocInstall| to install coc extensions from vim's command line.

To make coc.nvim install extensions on startup, use |g:coc_global_extensions|.

To use package manager other than npm (like `yarn` or `pnpm`), use
|coc-config-npm-binPath|.

To customize npm registry for coc.nvim add `coc.nvim:registry` in your
# `~/.npmrc`, like:
>
```
coc.nvim:registry=https://registry.mycompany.org/
```
<
To customize extension folder, configure |g:coc_data_home|.

# Uninstall global extensions: ~

Use |:CocUninstall|.

# Update global extensions: ~

Use |:CocUpdate| or |:CocUpdateSync|.

To configure extension behavior, see |coc-config-extensions|.

# Manage extensions: ~

Use |coc-list-extensions| or |CocAction('extensionStats')| to get list of extensions.

==============================================================================
CONFIGURATION						**coc-configuration**

The configuration of coc.nvim is stored in file named "coc-settings.json".

Configuration properties are contributed by coc.nvim itself and coc.nvim
extensions.  See |coc-config| for builtin configurations.

The configuration files are all in JSON format (with comment supported), it's
recommended to enable JSON completion and validation by install the `coc-json`
extension:
>
```
:CocInstall coc-json
```
<
To fix the highlight of comment, use:
>
```
autocmd FileType json syntax match Comment +\/\/.\+$+
```
<
in your vimrc.

# Global configuration file: ~

Command |:CocConfig| will open (create when necessary) a user settings
file in the folder returned by |coc#util#get_config_home()|.

The user configuration value could be overwritten by API |coc#config()| or
|g:coc_user_config|.

The global configuration file can be created in another directory by setting
|g:coc_config_home| in your vimrc like: >

```
let g:coc_config_home = '/path/to/folder'
```

# Folder configuration file: ~

To create a local configuration file for a specific workspace folder, use
|:CocLocalConfig| to create and open `.vim/coc-settings.json` in current
workspace folder.

Folder configuration would overwrite user configuration.

Note: the configuration file won't work when the parent folder is not resolved
as workspace folder, it's best practice to start vim inside workspace folder,
see |coc-workspace-folders|.

```
						*coc-configuration-expand*
# Variables expands: ~
```

Variables would be expanded in string values of configuration, supported
variables:

  • `${userHome}` the path of the user's home folder
  • `${cwd}` current working directory of vim.

You can also reference environment variables through the `${env:name}` syntax
(for example, `${env:USERNAME}`), no expand happens when env not exists.

Configurations that requires file paths (ex:
# |coc-config-workspace-ignoredFolders|) support expand `~` at the beginning of
the filepath to user's home and some additional variables:

  • `${workspaceFolder}` the current opened file's workspace folder.
  • `${workspaceFolderBasename}` the name of the workspace folder opened in
    coc.nvim without any slashes (/).
  • `${file}` the current opened file.
  • `${fileDirname}` the current opened file's dirname.
  • `${fileExtname}` the current opened file's extension.
  • `${fileBasename}`  the current opened file's basename
  • `${fileBasenameNoExtension}` the current opened file's basename with no file extension.

```
						*coc-configuration-scope*
# Configuration scope: ~
```

A configuration could be one of three different configuration scopes:

  • `"application"` the configuration could only be used in user configuration
    file.

  • `"resource"` the configuration could be used in user and workspace folder
    configuration file.

  • `"language-overridable"` the configuration could be used in user and
    workspace folder configuration file, and can be use used in language scoped
    configuration section like `[typescript][json]`.  For example: >

      // disable inlay hint for some languages
      "[rust][lua][c]": {
         "inlayHint.enable": false
      }
<
==============================================================================
FLOATING WINDOWS					**coc-floating**

Floating windows/popups are created by |api-floatwin| on neovim or |popupwin|
on vim.
```
						*coc-floating-scroll*
# Scroll floating windows: ~
```

See |coc#float#has_scroll()| for example.

Note: use |coc#pum#scroll()| for scroll popup menu.

```
						*coc-floating-close*
# Close floating windows: ~
```

To close all floating windows/popups use |coc#float#close_all()| or
|popup_clear()| on vim.  Or you can use <CTRL-w>o on neovim which close all
split windows as well.

To close single floating window/popup, use |coc#float#close()|.

```
						*coc-floating-focus*
# Focus floating windows: ~
```

On neovim, use <CTRL-w>w (or |<Plug>(coc-float-jump)|) could focus a floating
window just created (if it's focusable).  It's not allowed to focus popups on
vim, unless it's using a terminal buffer.

```
						*coc-floating-config*
# Configure floating windows: ~
```

To set custom window options on floating window create, use autocmd
|CocOpenFloat| or |CocOpenFloatPrompt|.

# Related variables: ~

  • |g:coc_last_float_win|
  • |g:coc_borderchars|
  • |g:coc_border_joinchars|
  • |g:coc_markdown_disabled_languages|

# Related highlight groups: ~

  • |CocFloating| For floating window background.
  • |CocFloatBorder| Default border highlight group of floating window.
  • |CocFloatDividingLine| For dividing lines.
  • |CocFloatActive| For active parts.
  • |CocMenuSel| For selected line.

To customize floating windows used by popup menu, use:

  • |coc-config-suggest-floatConfig|
  • |coc-config-suggest-pumFloatConfig|

For floating windows created around cursor, like diagnostics, hover and
signature use |coc-config-floatFactory-floatConfig| for common float
configurations. For further customization, use:

  • |coc-config-diagnostic-floatConfig|
  • |coc-config-signature-floatConfig|
  • |coc-config-hover-floatConfig|

For customize dialog windows, use |coc-config-dialog|.
For customize notification windows, use |coc-config-notification|.

Configure |coc-preferences-enableMessageDialog| to show user non-interactive
or interactive messages as notifications. To enable a more flexible user
interaction with the messages check |coc-preferences-messageDialogKind| and
|coc-preferences-messageReportKind|

Use |coc-preferences-messageDialogKind| to configure how interactive messages
which require some user input are shown to the user this configuration
supersedes the |coc-preferences-enableMessageDialog|.

Use |coc-preferences-messageReportKind| to configure how regular non-interactive
messages are reported to the user, that will tell coc how to show regular
plain text messages to the user.

==============================================================================
LSP FEATURES 						**coc-lsp**

Most features of LSP 3.17 are supported, checkout the specification at
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/

# Features not supported: ~

  • Telemetry.
  • Inline values for debugger.
  • Notebook document.

LSP features only works with attached documents, see |coc-document-attached|.

To check exists providers of current buffer, use command
`:CocCommand document.checkBuffer` or API |CocHasProvider()|.

For historic reason, some features automatically works by default, but some
are not.

# Features automatically work by default: ~

  • Trigger completion after text insert |coc-completion|.
  • Trigger inline completion |coc-inlineCompletion|
  • Diagnostics refresh |coc-diagnostics|.
  • Pull diagnostics |coc-pullDiagnostics|.
  • Trigger signature help |coc-signature|.
  • Inlay hints |coc-inlayHint|

Most features could be toggled by |coc-configuration| and some vim variables.

To disable all features that automatically work, use configuration:
>
    "suggest.autoTrigger": "none",
    "diagnostic.enable": false,
    "pullDiagnostic.onChange": false,
    "signature.enable": false,
    "inlayHint.enable": false,
<
# Features require enabled by configuration: ~

  • Semantic highlights |coc-semantic-highlights|.
  • Document color highlights |coc-document-colors|.
  • Code lens, |coc-code-lens|
  • Linked editing, |coc-linked-editing|.
  • Format on type, enabled by |coc-preferences-formatOnType|
  • Format on save, enabled by |coc-preferences-formatOnSave|.

# Features requested by user: ~

  • Locations related (including definitions, references etc.) |coc-locations|
  • Invoke code action |coc-code-actions|.
  • Show call hierarchy tree |coc-callHierarchy|.
  • Show type hierarchy tree |coc-typeHierarchy|
  • 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 information |coc-hover|.
  • Rename symbol under cursor |coc-rename|.
  • Open link under cursor |coc-document-links|.
  • Selection range |coc-selection-range|
  • Create folding ranges |coc-fold|.

For convenient, some actions have associated |coc-key-mappings| provided.
Prefer |CocAction()| for more options.

# Features triggered by languageserver: ~

  • Show message notification (use |coc-notification|).
  • Show message request (use |coc-dialog-menu|).
  • Log message notification (use `:CocCommand workspace.showOutput` to show
  output).
  • Show document request (opened by vim or your browser for url).
  • Work done progress (use |coc-notification|).

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**

An associated 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', (could be bypassed by
  |b:coc_force_attach|).
  • Buffer variable |b:coc_enabled| is `0`.
  • 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.

------------------------------------------------------------------------------
HOVER							**coc-hover**

Hover feature provide information at a given text document position, normally
include type information and documentation of current symbol.

# Hover functions: ~

  • |CocAction('doHover')| Show hover information at cursor position.
  • |CocAction('definitionHover')||| Show hover information with definition
  context at cursor position.
  • |CocAction('getHover')| Get hover documentations at cursor position.

```
						*coc-hover-example*
# Hover key-mapping example: ~
```
>
  nnoremap <silent> K :call ShowDocumentation()<CR>
  " Show hover when provider exists, fallback to vim's builtin behavior.
  function! ShowDocumentation()
    if CocAction('hasProvider', 'hover')
      call CocActionAsync('definitionHover')
    else
      call feedkeys('K', 'in')
    endif
  endfunction
<
------------------------------------------------------------------------------
COMPLETION						**coc-completion**

Vim's builtin completion is not used. The default completion works like
completion in VSCode:

  • Completion is automatically triggered by default.
  • Selection is enabled by default, use |coc-config-suggest-noselect| to
    disable default selection.
  • When selection is enabled and no preselect item exists, the first complete
    item will be selected (depends on |coc-config-suggest-selection|).
  • Snippet expand and additional edits only work after confirm completion
    |coc#pum#confirm()|.
  • |'completeopt'| is not used and APIs of builtin popupmenu not work.

```
						*coc-completion-default*
# Default Key-mappings: ~
```

To make the new completion works like the builtin completion, without any
additional configuration, the following key-mappings are used when the {lhs}
is not mapped:

  • `<C-n>` navigate to next complete item or inline complete item.
  • `<C-p>` navigate to previous complete item or inline complete item.
  • `<down>` navigate to next complete item (without word insert) or inline
    complete item.
  • `<up>` navigate to previous complete item (without word insert) or inline
    complete item.
  • `<C-e>` cancel the completion or inline completion.
  • `<C-y>` confirm completion or accept current inline complete item.

Use <PageDown> and <PageUp> to scroll: >

  inoremap <silent><expr> <PageDown> coc#pum#visible() ? coc#pum#scroll(1) : "\<PageDown>"
  inoremap <silent><expr> <PageUp> coc#pum#visible() ? coc#pum#scroll(0) : "\<PageUp>"
<
Note: <CR> and <Tab> are not remapped by coc.nvim.

```
						*coc-completion-variables*
# Related variables: ~
```

  • Disable completion for buffer: |b:coc_suggest_disable|
  • Disable specific sources for buffer: |b:coc_disabled_sources|
  • Disable words for completion: |b:coc_suggest_blacklist|
  • Add additional keyword characters: |b:coc_additional_keywords|, the
    buffer keyword characters are used for filter completion items instead of
    trigger completion, see |'iskeyword'|.

```
						*coc-completion-functions*
# Related functions: ~
```

  • Trigger completion with options: |coc#start()|.
  • Trigger completion refresh: |coc#refresh()|.
  • Select and confirm completion: |coc#pum#select_confirm()|.
  • Check if the custom popupmenu is visible: |coc#pum#visible()|.
  • Select the next completion item: |coc#pum#next()|.
  • Select the previous completion item: |coc#pum#prev()|.
  • Cancel completion and reset trigger text: |coc#pum#cancel()|.
  • Confirm completion: |coc#pum#confirm()|.
  • Close the popupmenu only: |coc#pum#stop()|.
  • Get information about the popupmenu: |coc#pum#info()|.
  • Select specific completion item: |coc#pum#select()|.
  • Insert word of selected item and finish completion: |coc#pum#insert()|.
  • Insert one more character from current complete item: |coc#pum#one_more()|.
  • Scroll popupmenu: |coc#pum#scroll()|.

```
						*coc-completion-customize*
# Customize completion: ~
```

Use |coc-config-suggest| to change the completion behavior.

Use |'pumwidth'| for configure the minimal width of the popupmenu and |'pumheight'|
for its maximum height.

Related Highlight groups:
```
|CocPum| 	for highlight groups of customized pum.
|CocSymbol| 	for kind icons.
|CocMenuSel| 	for background highlight of selected item.
|CocPumVirtualText| for virtual text when enabled by
|coc-config-suggest-virtualText|.
```

Note: background, border, title and winblend are configured by
|coc-config-suggest-floatConfig|.

# Example user key-mappings: ~
```
						*coc-completion-example*
```

Note: use command `:verbose imap` to check current insert key-mappings when
your key-mappings not work.

Use <tab> and <S-tab> to navigate completion list: >

  function! CheckBackspace() abort
    let col = col('.') - 1
# return !col || getline('.')[col - 1]  =~ '\s'
  endfunction

  " Insert <tab> when previous text is space, refresh completion if not.
  inoremap <silent><expr> <TAB>
```
\ coc#pum#visible() ? coc#pum#next(1):
\ CheckBackspace() ? "\<Tab>" :
\ coc#refresh()
```
  inoremap <expr><S-TAB> coc#pum#visible() ? coc#pum#prev(1) : "\<C-h>"

Use <c-space> to trigger completion: >

  if has('nvim')
    inoremap <silent><expr> <c-space> coc#refresh()
  else
    inoremap <silent><expr> <c-@> coc#refresh()
  endif
<
Use <CR> to confirm completion, use: >

  inoremap <expr> <cr> coc#pum#visible() ? coc#pum#select_confirm() : "\<CR>"
<
To make <CR> to confirm selection of selected complete item or notify coc.nvim
to format on enter, use: >

  inoremap <silent><expr> <CR> coc#pum#visible() ? coc#pum#select_confirm()
```
			\: "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"
```

Map <tab> for trigger completion, completion confirm, inline completion accept,
snippet expand and jump like VSCode: >

  inoremap <silent><expr> <TAB>
    \ coc#pum#visible() ? coc#pum#select_confirm() :
    \ coc#inline#visible() ? coc#inline#accept() :
    \ coc#expandableOrJumpable() ?
    \ "\<C-r>=coc#rpc#request('doKeymap', ['snippets-expand-jump',''])\<CR>" :
    \ CheckBackspace() ? "\<TAB>" :
    \ coc#refresh()

  function! CheckBackspace() 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.

------------------------------------------------------------------------------
INLINE COMPLETION					**coc-inlineCompletion**

Inline Completion is a smart, lightweight alternative to traditional
IntelliSense, offering faster, context-aware suggestions without disrupting
your workflow.  Inline completion is automatically triggered after document
contents synchronize on insert mode by default.

Use command `:CocCommand document.checkInlineCompletion` to check inline
completion feature of current buffer.

```
						*coc-inlineCompletion-default*
# Default Key-mappings: ~
```

Inline completion and default completion shares default key mappings for
navigate and finish actions. see |coc-completion-default|.  To accept inline
completion when pum is visible, finish the completion first or use
|coc#inline#accept()|.

```
						*coc-inlineCompletion-functions*
# Related functions: ~
```

  • Trigger inline completion: |coc#inline#trigger()|.
  • Check if inline completion visual text exists: |coc#inline#visible()|.
  • Cancel inline completion: |coc#inline#cancel()|.
  • Accept inline completion: |coc#inline#accept()|.
  • Navigate to next: |coc#inline#next()|.
  • Navigate to previous: |coc#inline#prev()|.

```
						*coc-inlineCompletion-customize*
# Customize completion: ~
```

Use |coc-config-inlineSuggest| to change the inline completion behavior.
To disable inline completion for special buffers, use language overridable
configuration in coc-settings.json like: >

```
"[javascript][typescript]": {
	"inlineSuggest.autoTrigger": false
}
```
<
Which disable auto trigger only, or use |b:coc_inline_disable| to disable
trigger inline completion completely.

Related Highlight groups:
```
|CocInlineVirtualText| for virtual text highlight.
|CocInlineAnnotation| for annotation highlight.
```

------------------------------------------------------------------------------
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.

See |coc-highlights-diagnostics| for diagnostic related highlight groups.

```
						*coc-diagnostics-refresh*
# Changes on diagnostics refresh ~
```

  • Add highlights for diagnostic ranges and virtual text (when enabled on
  neovim or vim >= 9.0.0067), 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.

See |coc-highlights-diagnostics| for highlight groups used by diagnostics.

```
						*coc-diagnostics-toggle*
# Enable and disable diagnostics ~
```

Use |coc-config-diagnostic-enable| to toggle diagnostics feature.

Use |CocAction('diagnosticToggle')| for enable/disable diagnostics feature.

Use |CocAction('diagnosticToggleBuffer')| 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')|.

```
						*coc-diagnostics-jump*
# Jump between diagnostics ~
```

Use key-mappings:

```
|<Plug>(coc-diagnostic-next)| jump to diagnostic after cursor position.
|<Plug>(coc-diagnostic-prev)| jump to diagnostic before cursor position.
|<Plug>(coc-diagnostic-next-error)| jump to next error.
|<Plug>(coc-diagnostic-prev-error)| jump to previous error.
```

Diagnostic may have related location, to jump to related location, use:
>
 	:CocCommand workspace.diagnosticRelated
<
# Check diagnostics ~

Use |coc-list-diagnostics| to open |coc-list| with all available diagnostics.
Use API |CocAction('diagnosticList')| to get list of all diagnostics.

Use |:CocDiagnostics| to open vim's location list with diagnostics of current
buffer. To automatically close the location list window, use autocmd
|CocDiagnosticChange| with |CocAction('diagnosticList')|.

------------------------------------------------------------------------------
PULL DIAGNOSTICS SUPPORT 				**coc-pullDiagnostics**

Diagnostics are pulled for visible documents when supported by languageserver.
Pull for workspace diagnostics is also enabled by default.

Document diagnostics are pulled on change by default, and can be
configured to be pulled on save.

Checkout |coc-config-pullDiagnostic| for related configurations.

------------------------------------------------------------------------------
LOCATIONS SUPPORT 					**coc-locations**

There're different kinds of locations, including "definitions", "declarations",
"implementations", "typeDefinitions" and "references".

# Key-mappings for invoke locations request ~

  • |<Plug>(coc-definition)|
  • |<Plug>(coc-declaration)|
  • |<Plug>(coc-implementation)|
  • |<Plug>(coc-type-definition)|
  • |<Plug>(coc-references)|
  • |<Plug>(coc-references-used)|

Error will be shown when the buffer not attached |coc-document-attached|.
Message will be shown when no result found.

# Location jump behavior ~

When there's only one location returned, the location is opened by command
specified by |coc-preferences-jumpCommand| ("edit" by default), context mark
is added by |m'|, so you can jump back previous location by <C-o>.

When multiple locations returned, |coc-list-location| is opened for preview
and other further actions.

To use |coc-list-location| for single location as well, use
|coc-locations-api| (instead key-mappings provided by coc.nvim).

To change default options of |coc-list-location| or use other plugin for
list of locations, see |g:coc_enable_locationlist|.

To use vim's quickfix for locations, use configuration
|coc-preferences-useQuickfixForLocations|.

To use vim's tag list for definitions, use |CocTagFunc()|.

```
						*coc-locations-api*
# Related APIs ~
```

------------------------------------------------------------------------------
RENAME 							**coc-rename**

Rename provides workspace-wide rename of a symbol. Workspace edit
|coc-workspace-edit| is requested and applied to related buffers when
confirmed.

Check if current buffer has rename provider with
`:echo CocAction('hasProvider', 'rename')`

# Rename key-mappings: ~

  • |<Plug>(coc-rename)|

# Rename functions: ~

  • |CocAction('rename')| Rename the symbol under the cursor.
  • |CocAction('refactor')| Open refactor buffer for all references (including
    definitions), recommended for function signature refactor.

# Rename local variable: ~

Use command `:CocCommand document.renameCurrentWord` which uses |coc-cursors|
to edit multiple locations at the same time and defaults to word extraction
when rename provider doesn't exist.

# Rename configuration: ~

Use |coc-preferences-renameFillCurrent| to enable/disable populating prompt
window with current variable name.

------------------------------------------------------------------------------
SIGNATURE HELP 						**coc-signature**

Signature help for functions is shown automatically when user
types trigger characters defined by the provider, which will use floating
window/popup to show relevant documentation.

Use |CocAction('showSignatureHelp')| to trigger signature help manually.

Note: error will not be thrown when provider does not exist or nothing is returned
by languageserver, use `echo CocAction('hasProvider', 'signature')` to check
if a signature help provider exists.

Use |coc-config-signature| to change default signature help behavior.

|CocFloatActive| is used to highlight activated parameter part.

------------------------------------------------------------------------------
INLAY HINT 						**coc-inlayHint**

Inlay hint is enabled for all filetypes by default.  Inlay hint uses virtual
text feature of vim.  Vim9 or neovim >= 0.10 required to insert the virtual
text at correct position.

Note: you may need configure extension or languageserver to make inlay hint
works.

To temporarily toggle inlay hint specific buffer, use command: >

```
:CocCommand document.enableInlayHint {bufnr}
:CocCommand document.disableInlayHint {bufnr}
:CocCommand document.toggleInlayHint {bufnr}
```
<
current bufnr is used when `{bufnr}` not specified.

# Change highlight group: ~

  • |CocInlayHint|
  • |CocInlayHintType|
  • |CocInlayHintParameter|

# Configure inlay hint support: ~

|coc-config-inlayHint|

------------------------------------------------------------------------------
FORMAT 							**coc-format**

Some tools may reload buffer from disk file during format, coc.nvim only
apply `TextEdit[]` to the document.

Don't be confused with vim's indent feature, configure/fix the 'indentexpr' of
your buffer if the indent is wrong after character insert. (use
|coc-format-ontype| might helps with the indent)

```
						*coc-format-options*
# Format options: ~
```

Buffer options that affect document format: 'eol', 'shiftwidth' and
'expandtab'.

  • |b:coc_trim_trailing_whitespace| Trim trailing whitespace on a line.
  • |b:coc_trim_final_newlines| Trim all newlines after the final newline at
    the end of the file.

Those options are converted to `DocumentFormattingOptions` and transferred to
languageservers before format.  Note: the languageservers may only support
some of those options.

```
						*coc-format-document*
# Format full document: ~
```

Choose "editor.action.formatDocument" from |coc-list-commands|.
Or use |CocAction('format')|, you can create a command like: >

```
command! -nargs=0 Format :call CocActionAsync('format')
```
<
to format current buffer.

```
						*coc-format-ontype*
# Format on type: ~
```

Format on type could be enabled by |coc-preferences-formatOnType|.

Use `:CocCommand document.checkBuffer` to check if `formatOnType` provider
exists for current buffer.

To format on <CR>, create key-mapping of <CR> that uses |coc#on_enter()|.

If you don't like the behavior on type bracket characters, configure
|coc-preferences-bracketEnterImprove||.

```
						*coc-format-selected*
# 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)
<
```
						*coc-format-onsave*
# Format on save: ~
```

To enable format on save, use configuration |coc-preferences-formatOnSave|.

Or create |BufWritePre| autocmd like: >

```
autocmd BufWritePre * call CocAction('format')
```
<
Note the operation have to synchronized, avoid use |CocActionAsync()|.
Note to skip the autocmd, use `:noa w` to save the buffer.

The operation on save will block your vim, to not block too long time, the
operation will be canceled after 0.5s, configured by
|coc-preferences-willSaveHandlerTimeout|

------------------------------------------------------------------------------
CODE ACTION 						**coc-code-actions**

Code actions are used for ask languageserver to provide specific kind code
changes.

Possible code action kinds:

  • `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.

DOCUMENT HIGHLIGHTS 					**coc-document-highlights**

Document highlights is used for highlight same symbols of current document
under cursor.

To enable highlight on CursorHold, create an autocmd like this: >

```
autocmd CursorHold * call CocActionAsync('highlight')
```
<
See |coc-config-documentHighlight| for related configurations.
See |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 COLORS 					**coc-document-colors**

Document colors added color highlights to vim buffers.  To enable document
color highlights, use |coc-config-colors-enable|.

Note: the highlights define gui colors only, make use you have 'termguicolors'
enabled (and your terminal support gui colors) if you're using vim in
terminal.

To pick a color from system color picker, use |CocAction('pickColor')| or
choose `editor.action.pickColor` from |:CocCommand|.

Note: pick color may not work on your system.

To change color presentation, use |CocAction('colorPresentation')| or choose
`editor.action.colorPresentation` from |:CocCommand|.

To toggle color highlight of current buffer, choose
`document.toggleColors` from |:CocCommand|

To highlights colors without languageservers, install
https://github.com/neoclide/coc-highlight

==============================================================================
DOCUMENT LINKS 						**coc-document-links**

Check if current buffer have documentLink provider by
`:echo CocAction('hasProvider', 'documentLink')`

Highlight and tooltip of the links could be configured by |coc-config-links|.

Use |coc-list-links| to manage list of links in current document.

# Document link key-mappings: ~

|<Plug>(coc-openlink)|

# Document link functions: ~

  • |CocAction('openLink')| Open link under cursor.
  • |CocAction('links')| Get link list of current buffer.

------------------------------------------------------------------------------
SNIPPETS SUPPORT 					**coc-snippets**

Snippets engine of coc.nvim support both VSCode snippets and ultisnips
snippets format.

The completion items with snippet format has label ends with
# |coc-config-suggest-snippetIndicator| (`~` by default).

Confirm the completion by |coc#pum#confirm()| or |coc#pum#select_confirm()| to
expand the snippet and execute other possible actions of selected complete
item.

# Jump snippet placeholders: ~

|g:coc_snippet_next| and |g:coc_snippet_prev| are used to jump placeholders on
both select mode and insert mode, which defaults to <C-j> and <C-k>.  Buffer
key-mappings are created on snippet activate, and removed on snippet
deactivate.

# Deactivate snippet session: ~

A snippet session would be deactivated under the following conditions:

  • The change affects the snippet and code outside.
  • Autocmd |InsertEnter| triggered outside snippet.
  • Jump to the final placeholder.

Use |CocOpenLog| to checkout the cancel reason.
Use |CocAction('snippetCancel')| for cancel snippet session manually.

To load and expand custom snippets, install `coc-snippets` extension by
command: >

```
:CocInstall coc-snippets
```
<
# Nested snippets: ~

Snippets can be nested, when jump to tabstop of parent snippet, it's not
possible to jump back again (works like UltiSnip).

# Related configurations: ~

  • |g:coc_snippet_prev|
  • |g:coc_snippet_next|
  • |g:coc_selectmode_mapping|
  • |coc-config-suggest-snippetIndicator|

    placeholder of next expanded snippet.
  • |b:coc_snippet_active| Check if snippet session is activated.
  • |CocJumpPlaceholder| Autocmds triggered after placeholder jump.
  • |CocSnippetVisual| For highlight of current placeholders when the
    highlight is enabled.

------------------------------------------------------------------------------
WORKSPACE SUPPORT 					**coc-workspace**

```
						*coc-workspace-folders*
# Workspace folders ~
```

Unlike VSCode which prompt you to open folders, workspace folders of coc.nvim
are resolved from filepath after document attached.

A list of file/folder names is used for resolve workspace folder, the patterns
could comes from:

  • |b:coc_root_patterns|
  • "rootPatterns" field of languageserver in |coc-config-languageserver|.
  • "rootPatterns" contributions from coc.nvim extensions.
  • |coc-config-workspace-rootPatterns|

Workspace folder is resolved from cwd of vim first (by default) 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.

Use `:CocCommand workspace.workspaceFolders` to echo current workspaceFolders.

To manage current workspace folders, use |coc-list-folders|

To get related root patterns of current buffer, use |coc#util#root_patterns()|

```
						*coc-workspace-edits*
# Workspace edit ~
```

Workspace edit is used to apply changes for multiple buffers(and/or files), the
edit could contains 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.

```
						*coc-workspace-rename*
# Rename current file ~
```

To move or rename current file, it's recommended to use
`:CocCommand workspace.renameCurrentFile` which makes vim reload current
buffer and send expected events to language servers.
```
						*coc-workspace-output*
# Output channels ~
```

Output channels shows logs for user to inspect.  Use command
`workspace.showOutput` to open output channel.

Builtin channels:

- `watchman` shows watchman related logs.
- `extensions` shows extension install and update related logs.

|coc-languageserver| and |coc-extensions| could contribute output channels.

------------------------------------------------------------------------------
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 |coc-refactor-buffer|.
  • Use |:CocSearch| to open searched locations with |coc-refactor-buffer|.
  • 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 activated.

```
						*coc-refactor-buffer*
```

Refactor buffer is a specific buffer with |coc-cursors| enabled, normally
opened by |CocAction('refactor')| and |:CocSearch|. When the refactor buffer
saved, related buffers and files would be changed at once, workspace edits
would be applied, which could be undo and redo, see |coc-workspace-edits|.

Check out |coc-config-refactor| for related configuration.

Use <CR> to open buffer at current position in split window.
Use <Tab> to invoke tab open or remove action with current code chunk.

--------------------------------------------------------------------------------
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 |w: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|.
  • Enable auto preview by |coc-config-outline-togglePreviewKey|.

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.

```
						*coc-outline-example*
```

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 split |coc-tree| window with locations for incoming or
outgoing calls of function under cursor position.

Call hierarchy window is opened by |CocAction('showIncomingCalls')| and
|CocAction('showOutgoingCalls')|.  The tree view window has |w:cocViewId| set
to "CALLS".

Call hierarchy is configured by |CocSymbol|, |coc-config-callHierarchy| and
|coc-config-tree|.

Related ranges are highlighted with |CocSelectedRange| highlight group in
opened buffer.

|coc-dialog-menu| could be invoked by |coc-config-tree-key-actions| (default
to <tab>).  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.

--------------------------------------------------------------------------------
TYPE HIERARCHY						**coc-typeHierarchy**

A type hierarchy is a split |coc-tree| window with locations for super types
or sub types from types at current position.

Type hierarchy window is opened by |CocAction('showSuperTypes')| and
|CocAction('showSubTypes')|.  The tree view window has |w:cocViewId| set to
"TYPES".

Type hierarchy is configured by |CocSymbol|, |coc-config-typeHierarchy| and
|coc-config-tree|.

Actions are the same as |coc-callHierarchy|.

--------------------------------------------------------------------------------
SEMANTIC HIGHLIGHTS					**coc-semantic-highlights**

Semantic tokens are used to add additional color information to a buffer that
depends on language specific symbol information.

Use |coc-config-semanticTokens-enable| 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
<
  • Clear semantic highlight by: >

  " Clear semantic tokens highlight of current buffer
  :CocCommand semanticTokens.clearCurrent

  " Clear semantic tokens highlight for all buffers
  :CocCommand semanticTokens.clearAll
<
See |CocSem| to customize semantic token highlight groups.

See |coc-config-semanticTokens| for related configurations.

--------------------------------------------------------------------------------
FOLD 							**coc-fold**

Check if current buffer have fold provider by
`:echo CocAction('hasProvider', 'foldingRange')`

Use |CocAction('fold')| to create folds by request the languageserver and
create manual folds on current window.

--------------------------------------------------------------------------------

CodeLens are not shown by default, use |coc-config-codeLens-enable| to enable,
you may also need enable codeLens feature by configure extension or
languageserver.

Check if current buffer have code lens provider by
`:echo CocAction('hasProvider', 'codeLens')`

To temporarily toggle codeLens of current buffer, use command
`:CocCommand document.toggleCodeLens`

To invoke command from codeLens, use |<Plug>(coc-codelens-action)|.

Use |CocCodeLens| for highlight of codeLens virtual text.

Code lens are automatically requested on buffer create/change, checkout
|coc-config-codeLens| for available configurations.

--------------------------------------------------------------------------------
LINKED EDITING 						**coc-linked-editing**

Linked editing feature enables editing multiple linked ranges at the same time,
for example: html tags.  The linked editing ranges would be highlighted with
|CocLinkedEditing| when activated.

Check if current buffer have linked editing provider by

Linked editing feature is disabled by default, use
|coc-preferences-enableLinkedEditing| to enable.

==============================================================================
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 after current
cursor position.

**<Plug>(coc-diagnostic-prev)** Jump to previous diagnostic position before
current cursor position.

**<Plug>(coc-diagnostic-next-error)** Jump to next diagnostic error position.

Format selected range, works on both |visual-mode| and |normal-mode|,
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

```

# 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.
`--hidden`: Search hidden files and directories.
`--no-ignore-vcs`:  Don't respect version control ignore files
(.gitignore, etc.).
`--no-ignore`: Don't respect ignore files (.gitignore, .ignore, etc.).
`-w` `--word-regexp`: Only show matches surrounded by word boundaries.
`-S` `--smart-case`: Searches case insensitively if the pattern is all
lowercase. Search case sensitively otherwise.
`--no-config`: Never read configuration files.
`-x` `--line-regexp`: Only show matches surrounded by line boundaries.

# 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.
```

```
" make error texts have a red color
autocmd ColorScheme solarized
```
              \ highlight CocErrorHighlight ctermfg=Red  guifg=#ff0000

<
Use |:highlight| with group name to check current highlight.

LIST CONFIGURATION					**coc-list-configuration**

Use `coc-settings.json` for configuration of lists.

Configuration of list starts with 'list.'.

See |coc-config-list| or type `list.` in your settings file to get completion
list (requires coc-json installed).

For configuration of a specified list, use section that starts with:
`list.source.{name}`, where `{name}` is the name of list.

# Change default action: ~

If you want to use `tabe` as default action of symbols list, you can use:
>
```
// change default action of symbols
"list.source.symbols.defaultAction": "tabe"
```
<
in your coc-settings.json

# Change default options: ~

To change |coc-list-options| for source with {name}, use
`list.source.{name}.defaultOptions` configuration like: >

```
// make symbols list use normal mode and interactive by default
"list.source.symbols.defaultOptions": ["--interactive", "--number-select"],
```
<
Note: some list like symbols only work in interactive mode, you must
include `--interactive` in `defaultOptions`.

Note: default options will not be used when there're options passed
with |:CocList| command.

# Change default arguments: ~

Use `list.source.{name}.defaultArgs` setting like: >

```
// use regex match for grep source
"list.source.grep.defaultArgs": ["-regex"],
```

Note: default arguments used only when arguments from |:CocList| command is
empty.

Note: Type `?` on normal mode to get supported arguments of current list.

Configurations `"list.normalMappings"` and `"list.insertMappings"` are used
for customizing the list key-mappings, example: >

```
"list.insertMappings": {
	"<C-space>": "do:previewtoggle",
	"<C-_>": "do:help"
	"<C-r>": "do:refresh",

Dialog is special float window/popup that could response to user actions,
dialog have close button, border, title (optional), bottom buttons(optional).

Note bottom buttons work different on neovim and vim, on neovim you can
click the button since neovim allows focus of window, on vim you have to type
highlighted character to trigger button callback.

See |coc-config-dialog| for available configurations.

--------------------------------------------------------------------------------

```
						*coc-dialog-basic*

--------------------------------------------------------------------------------

```
						*coc-dialog-confirm*
```

A confirm dialog is used for user to confirm an action, normally created by
`window.showPrompt()` Confirm dialog uses filter feature on vim8 and
|getchar()| on Neovim.

The difference is you can operate vim on vim8, but not on neovim.

Supported key-mappings:

<C-c>         - force cancel, return -1 for callback.
<esc>, n, N   - reject the action, return 0 for callback.
y,Y           - accept the action, return 1 for callback.

--------------------------------------------------------------------------------

```
						*coc-dialog-input*
```

An input dialog request user input with optional default value, normally
created by `window.requestInput`, when `"coc.preferences.promptInput"` is
false, vim's command line input prompt is used instead.

On neovim, it uses float window, on vim8, it opens terminal in popup.

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.
<cr>                - accept current input selection of current item.

QuickPick related (available when created by |coc-dialog-quickpick|).

<C-f>               - scroll forward quickpick list.
<C-b>               - scroll backward quickpick list.

<C-k> <C-p> <up>    - move to previous item in quickpick list.
<C-t> <C-space>     - toggle selection of current item in quickpick list when
canSelectMany is supported.

Note on neovim, other insert mode key-mappings could work.

Note not possible to configure key-mappings on vim8, to customize key-mappings
on neovim, use |CocOpenFloatPrompt| with current buffer.

--------------------------------------------------------------------------------

```
						*coc-dialog-quickpick*
```

A quickpick is a input dialog in the middle with a float window/popup contains
filtered list items.

Fuzzy filter is used by default.

See |coc-dialog-input| for available key-mappings.

--------------------------------------------------------------------------------

```
						*coc-dialog-menu*
```

A menu dialog is used for pick a single item from list of items, extensions

--------------------------------------------------------------------------------

```
						*coc-dialog-picker*
```

A picker dialog is used for single/multiple selection. On neovim, it's
possible to toggle selection by mouse click inside the bracket. Extensions
could use `window.showPickerDialog` to create picker dialog.

Supported key-mappings:

<Esc> <C-c>          - cancel selection.
<cr>                 - confirm selection of current item, use

NOTIFICATION SUPPORT					**coc-notification**

Notification windows are created at the bottom right of the screen.

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|.

Use |coc-config-notification-disabledProgressSources| to disable progress
notifications for specific sources.

# Customize notifications: ~

  • Customize icons: |g:coc_notify|
  • Customize highlights: |CocNotification|
  • Customize configurations: |coc-config-notification|

# Related functions: ~

  • |coc#notify#close_all()|

  • |coc#notify#keep()|

==============================================================================

STATUSLINE SUPPORT					**coc-status**

Diagnostics info and other status info contributed by extensions could be
shown in statusline.

The easiest way is add `%{coc#status()}` to your 'statusline' option. Example: >

```
set statusline^=%{coc#status()}
```
<
Use |CocStatusChange| autocmd for automatically refresh statusline: >

```
autocmd User CocStatusChange redrawstatus
```
<
--------------------------------------------------------------------------------

```
						*coc-status-manual*
```

Create function like:
>
```
function! StatusDiagnostic() abort
  let info = get(b:, 'coc_diagnostic_info', {})
  if empty(info) | return '' | endif
  let msgs = []
  if get(info, 'error', 0)
    call add(msgs, 'E' . info['error'])
  endif
  if get(info, 'warning', 0)
    call add(msgs, 'W' . info['warning'])
  endif
  return join(msgs, ' ') . ' ' . get(g:, 'coc_status', '')
endfunction
```
<
Add `%{StatusDiagnostic()}` to your 'statusline' option.
