Some of the features include:~ - APIs that are compatible with both Vim (>= 8.0) and Neovim. - Loading VSCode-like extensions. - Configuring coc.nvim and its extensions by using JSON configuration file. - Configuring Language Servers that implement Language Server Protocol (LSP). It's designed to have a good integration with other Vim plugins as much as possible. Coc.nvim is configurable and you can control the features that you want through the options for the best experience. ============================================================================== REQUIREMENTS *coc-requirements* Note: this plugin requires Neovim >= 0.3.0 or Vim >= 8.0. * Neovim >= 0.3.0 or Vim >= 8.0 * NodeJS (download from https://nodejs.org/en/download/ or install through your favorite package manager) If those requirements are not satisfied, the plugin will not load at all. ============================================================================== 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, use code from the release branch. Or use Vim's built-in plugin ecosystem: > #!/bin/sh # for vim8 mkdir -p ~/.vim/pack/coc/start cd ~/.vim/pack/coc/start curl --fail -L https://github.com/neoclide/coc.nvim/archive/release.tar.gz|tar xzfv - # for neovim mkdir -p ~/.local/share/nvim/site/pack/coc/start cd ~/.local/share/nvim/site/pack/coc/start curl --fail -L https://github.com/neoclide/coc.nvim/archive/release.tar.gz|tar xzfv - ============================================================================== CONFIGURATION *coc-configuration* Configurations of coc.nvim are stored in file names `coc-settings.json` that can be opened using |:CocConfig| for user configuration file or |:CocLocalConfig| for local configuration file. The location of global configuration can be configured by `g:coc_config_home`. Configure |b:coc_root_patterns| for project root resolve. To enable JSON completion and validation support of the settings file, install the `coc-json` extension by command: CocInstall coc-json Check out https://github.com/neoclide/coc.nvim/wiki/Using-the-configuration-file for more details.

Tips:~ - 'completeopt' used by coc.nvim default to `noselect,menuone`. - Your 'completeopt' option would be changed and restored during completion, so you can still use `menu,preview` for Vim's built in completion. - Snippet expand and additional edit feature of LSP requires confirm completion to work. - Floating window is available on Neovim >= 0.4.0. ------------------------------------------------------------------------------ Example configuration:~ Map to trigger completion and navigate to the next item: > function! s:check_back_space() abort let col = col('.') - 1 return !col || getline('.')[col - 1] =~ '\s' endfunction inoremap \ pumvisible() ? "\" : \ check_back_space() ? "\" : \ coc#refresh() Map to trigger completion: > inoremap coc#refresh() < to confirm completion, use: > inoremap pumvisible() ? "\" : "\" < To make auto-select the first completion item and notify coc.nvim to format on enter, use: > inoremap pumvisible() ? coc#_select_confirm() \: "\u\\=coc#on_enter()\" Map for trigger completion, completion confirm, snippet expand and jump like VSCode. > inoremap \ pumvisible() ? coc#_select_confirm() : \ coc#expandableOrJumpable() ? "\=coc#rpc#request('doKeymap', ['snippets-expand-jump',''])\" : \ check_back_space() ? "\" : \ coc#refresh() function! s:check_back_space() abort let col = col('.') - 1 return !col || getline('.')[col - 1] =~# '\s' endfunction let g:coc_snippet_next = '' < Note: the `coc-snippets` extension is required for this to work. ============================================================================== INTERFACE *coc-interface* ------------------------------------------------------------------------------ Coc doesn't come with a default global keymap, you need to configure the mappings yourself. Key mappings *coc-key-mappings* Note: Mappings that start with `i_` works for insert mode `n_` works for normal mode, `v_` works for visual mode.

Note: requires selection ranges feature of language server, like: coc-tsserver, coc-python (coc-funcobj-i) *n_coc-funcobj-i* *v_coc-funcobj-i* Select inside function. Recommend mapping: xmap if (coc-funcobj-i) omap if (coc-funcobj-i) Note: Requires 'textDocument.documentSymbol' support from the language server. (coc-funcobj-a) *n_coc-funcobj-a* *v_coc-funcobj-a* Select around function. Recommended mapping: xmap af (coc-funcobj-a) omap af (coc-funcobj-a) Note: Requires 'textDocument.documentSymbol' support from the language server. (coc-classobj-i) *n_coc-classobj-i* *v_coc-classobj-i* Select inside class/struct/interface. Recommended mapping: xmap ic (coc-classobj-i) omap ic (coc-classobj-i) Note: Requires 'textDocument.documentSymbol' support from the language server. (coc-classobj-a) *n_coc-classobj-a* *v_coc-classobj-a* Select around class/struct/interface. Recommended mapping: xmap ac (coc-classobj-a) omap ac (coc-classobj-a) Note: Requires 'textDocument.documentSymbol' support from the language server. ------------------------------------------------------------------------------ VARIABLES *coc-variables* b:coc_enabled *b:coc_enabled* Set to `0` on buffer create if you don't want coc.nvim receive content from buffer, usually used for improve performance with large files. b:coc_root_patterns *b:coc_root_patterns* Root patterns used for resolving workspaceFolder for the current file, will be used instead of `"coc.preferences.rootPatterns"` setting. E.g.: > autocmd FileType python let b:coc_root_patterns = \ ['.git', '.env'] < b:coc_suggest_disable *b:coc_suggest_disable* Disable completion support of current buffer. E.g.: > " Disable completion for python autocmd FileType python let b:coc_suggest_disable = 1 b:coc_suggest_blacklist *b:coc_suggest_blacklist* Words for which completion should be disabled. E.g.: > " Disable completion for 'end' in lua files autocmd FileType lua let b:coc_suggest_blacklist = ["end"] b:coc_additional_keywords *b:coc_additional_keywords* Addition keyword characters for generate keywords. E.g.: > " Add keyword characters for css autocmd FileType css let b:coc_additional_keywords = ["-"] b:coc_current_function *b:coc_current_function* Function string that current cursor in. Set `"coc.preferences.currentFunctionSymbolAutoUpdate": true` in coc-settings.json to update it on CursorHold. g:coc_channel_timeout *g:coc_channel_timeout* Channel timeout in seconds for request to node client.

Note: not used when floating or preview window used for `doHover`. g:coc_start_at_startup *g:coc_start_at_startup* Start coc service on startup, use |CocStart| to start server when you set it to 0. Default: 1 g:coc_user_config *g:coc_user_config* User configuration object, define this variable when you can't use |coc#config()| g:coc_global_extensions *g:coc_global_extensions* Global extension names to install when they aren't installed, define this variable to a list of extension names when you can't use |coc#add_extension()| g:coc_cygqwin_path_prefixes *g:coc_cygqwin_path_prefixes* When running under cygwin, the node process will work with win32 paths, while your Vim process will work with POSIX paths. You can use this map to map between paths. For example, your root folder might be `c:/Users/myUser/workspace` mapped in cygwin as `/home/myUser/workspace`. In this situation, your node process might send the `c:/Users/myUser/workspace` path to your Vim process. To solve this, you need to define this map: `let g:coc_cygqwin_path_prefixes = ` ` \{'c:/Users/myUser': '/home/myUser'}` Deprecated, use `g:coc_uri_prefix_replace_patterns` instead. g:coc_uri_prefix_replace_patterns *g:coc_uri_prefix_replace_patterns* This map defines URI prefix replacements. This is useful in the case that an LSP requires code to adhere to a particular directory structure. For example, `/Users/myUser/workspace` can be mapped to `/home/myUser/workspace`. `let g:coc_uri_prefix_replace_patterns = ` ` \{'/Users': '/home'}` g:coc_enable_locationlist *g:coc_enable_locationlist* Use location list of coc.nvim when jump locations.
