==============================================================================
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 specified
by Language Server Protocol (3.16 for now).

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

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: 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 through `"suggest.autoTrigger": "none"` (or
`"suggest.autoTrigger": "trigger"`) in your configuration file.

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

Neovim >= 0.4.0 or Vim >= 8.1.1719.

NodeJS https://nodejs.org/ >= 14.14.0.

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
(unless you want to build from typescript source code).

To use Vim's native |packages| on Linux or MaxOS, 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 install
https://yarnpkg.com/ and run `yarn install` in project root of coc.nvim.

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

To provide LSP features of different filetypes, the user have to config
|coc-config-languageserver| or install coc extensions.

Coc extensions are more powerful since they could contribute json schemes,
commands, and use middleware methods of languageserver to provide better
results.  It's also possible to provide features that beyond LSP.

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

Install extensions from git (not recommended):~

- Download the source code.
- In project root, install dependencies and compile the code by `yarn 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 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 update extensions automatically, config |coc-preferences-extensionUpdateCheck|.

Manage extensions list:~

Use |coc-list-extensions| by `:CocList extensions` to open extensions list.
Use |CocAction('extensionStats')| to get list of extensions.

Single file extensions:~

All Javascript files that ends with `.js` inside the folder
|g:coc_config_home| + '/coc-extensions' are considered as coc extensions, for
example:
>
  const {window} = require('coc.nvim')

  exports.activate = context => {
    window.showInformationMessage("message from extension")
  }
<
==============================================================================
CONFIGURATION						*coc-configuration*

The configuration of coc.nvim is stored in file `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
<
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 can also be changed by API |coc#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, use
|:CocLocalConfig| to create and open `.vim/coc-settings.json` in current
workspace folder.

Folder configuration would overwrite user configuration.

							*coc-configuration-scope*
Configuration scope:~

A configuration could be one of three different configuration scopes:

- "application" the configuration could only be changed in user configuration
  file.

- "resource" the configuration could be changed in user and workspace folder
  configuration file.

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

==============================================================================
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 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.
- |CocFloatDividingLine| For dividing lines.
- |CocMenuSel| For selected line.
- |CocUnderline| For active parts.

To customize floating windows used by popup menu. Use configurations:

- |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|.

==============================================================================
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/

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

To check exists providers of current buffer, use command
`:CocCommand document.checkBuffer` or |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|.
- Pull diagnostics |coc-pullDiagnostics|.
- Trigger signature help |coc-signature|.
- Inlay hints |coc-inlayHint|

Most features could be disabled/enabled by |coc-configuration| and some
vim variables.

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-formatOnSaveFiletypes|.

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*

The builtin completion of vim is no longer used, the default completion
behavior works like VSCode:

- Completion is automatically triggered by default.
- Item selection is enabled by default, use |coc-config-suggest-noselect| to
  disable default selection.
- When selection enabled and no preselect item exists, recent used item that
  matched will be selected by default.
- Snippet and additional edits only work after confirm completion.
- 'completeopt' is not used and APIs of builtin popupmenu not work.

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

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

Use <C-n>, <C-p>, <up> and <down> to navigate completion list: >

  inoremap <silent><expr> <C-n> coc#pum#visible() ? coc#pum#next(1) : "\<C-n>"
  inoremap <silent><expr> <C-p> coc#pum#visible() ? coc#pum#prev(1) : "\<C-p>"
  inoremap <silent><expr> <down> coc#pum#visible() ? coc#pum#next(0) : "\<down>"
  inoremap <silent><expr> <up> coc#pum#visible() ? coc#pum#prev(0) : "\<up>"
<
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>"
<
Use <C-e> and <C-y> to cancel and confirm completion: >

  inoremap <silent><expr> <C-e> coc#pum#visible() ? coc#pum#cancel() : "\<C-e>"
  inoremap <silent><expr> <C-y> coc#pum#visible() ? coc#pum#confirm() : "\<C-y>"

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 trigger completion: |b:coc_suggest_blacklist|
- Add additional keyword characters: |b:coc_additional_keywords|

							*coc-completion-functions*
Related functions:~

- Trigger completion with options: |coc#start()|.
- Trigger completion refresh: |coc#refresh()|.
- Select and confirm completion: |coc#_select_confirm()|.
- Check if customized popupmenu is visible: |coc#pum#visible()|.
- Select next complete item: |coc#pum#next()|.
- Select previous complete 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 of the popupmenu: |coc#pum#info()|.
- Select specific complete item: |coc#pum#select()|.
- Insert word of selected item and finish completion: |coc#pum#insert()|.
- Scroll popupmenu: |coc#pum#scroll()|.

							*coc-completion-customize*
Customize completion:~

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

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

Related Highlight groups:
	|CocPum| 	for highlight groups of customized pum.
	|CocSymbol| 	for kind icons.
	|CocMenuSel| 	for background highlight of selected item.

Note: background, border 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#_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#_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>
    \ coc#pum#visible() ? coc#_select_confirm() :
    \ 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.

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

							*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.

Diagnostics highlights:~

See |coc-highlights-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.

Check all diagnostics~

Use |coc-list-diagnostics| to open |coc-list| with all available diagnostics.

Use API |CocAction('diagnosticList')| to get list of all diagnostics.

------------------------------------------------------------------------------
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~

- |CocAction('jumpDefinition')| Jump to definition locations.
- |CocAction('jumpDeclaration')| Jump to declaration locations.
- |CocAction('jumpImplementation')| Jump to implementation locations.
- |CocAction('jumpTypeDefinition')| Jump to type definition locations.
- |CocAction('jumpReferences')|| Jump to references.
- |CocAction('jumpUsed')| Jump to references without declarations.
- |CocAction('definitions')| Get definition list.
- |CocAction('declarations')| Get declaration list.
- |CocAction('implementations')| Get implementation list.
- |CocAction('typeDefinitions')| Get type definition list.
- |CocAction('references')| Get reference list.

Send custom locations request to languageserver:

- |CocLocations()|
- |CocLocationsAsync()|

------------------------------------------------------------------------------
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 which requires neovim >= 0.5.0 or vim >= 9.0.0067.

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

To temporarily toggle inlay hint of current buffer, use command
`:CocCommand document.toggleInlayHint`

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 insert new line.

							*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.  The languageservers may only support some of
those options.

							*coc-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.

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

Format on type is disabled by default, could be enabled by configurations:

- |coc-preferences-formatOnType|
- |coc-preferences-formatOnTypeFiletypes|

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:~

Use configuration |coc-preferences-formatOnSaveFiletypes|.

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 be timeout after 0.5s by default, configured by
|coc-preferences-willSaveHandlerTimeout|

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

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

Key-mappings for code actions:~

- |<Plug>(coc-fix-current)| Invoke quickfix action at current line if any.
- |<Plug>(coc-codeaction-cursor)| Choose code actions at cursor position.
- |<Plug>(coc-codeaction-line)| Choose code actions at current line.
- |<Plug>(coc-codeaction)| Choose code actions of current file.
- |<Plug>(coc-codeaction-selected)| Choose code actions from selected range.

Except for |<Plug>(coc-fix-current)| which invoke code action directly,
|coc-dialog-menu| would be shown for pick specific code action.

To invoke organize import action, use command like:
>
	command! -nargs=0 OR :CocCommand editor.action.organizeImport

Error would be shown when organize import code action not found.

------------------------------------------------------------------------------
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')
<
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 COLORS 					*coc-document-colors*

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

Note: the highlights define gui colors only, make use you have 'termguicolors'
enabled (and your terminal support gui colors) if you're not using gvim.

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|.

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')`

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

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 complete item with snippet format has label ends with
|coc-config-suggest-snippetIndicator| (`~` by default).

Select the complete item and confirm the completion by |coc#pum#confirm()| or
|coc#_select_confirm()| to expand the snippet of current selected complete
ttem.

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:

- |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|
- |g:coc_selectmode_mapping|
- |coc-config-suggest-snippetIndicator|
- |coc-config-suggest-preferCompleteThanJumpPlaceholder|

Related variables, highlights and autocmds:~

- |b:coc_snippet_active| Check if snippet session is activated.
- |CocSnippetVisual| For highlight of current placeholders.
- |CocJumpPlaceholder| AutocmdS triggered after placeholder jump.

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

							*coc-workspace-edits*
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 activated.

------------------------------------------------------------------------------
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|.
- Enable auto preview by |coc-config-outline-togglePreviewKey|.

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
<
------------------------------------------------------------------------------

|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:

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.

The feature requires vim >= 8.1.1719 or neovim >= 0.5.0.

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
<
See |CocSem| to customize semantic token highlight groups.

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

	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

	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:
>

	The escape for `{` is required because rg use regexp be default, or:
>
	:CocSearch -F import\ {\ Neovim
<
	for strict match.

Use `list.source.{name}.defaultOptions` setting 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.
