VimPlugin: Coc.nvim

coc.nvim aims to be intellisense (visualstudio) for vim.

• autocompletion
• outliner
• refactor-rename
• goto
• show-references

WARNING:

coc.nvim DOES NOT play nice with other autocompleters.

Languages

Languages can be installed dynamically with :CocInstall coc-python
or automatically like Plug 'neoclide/coc-tsserver', {'do': 'yarn install --frozen-lockfile'}.

python	unmaintained	coc-python
python	active	coc-pyright
sh/bash	active	coc-sh
ruby/rails	active	coc-solargraph
graphql	active	coc-graphql

Install

# archlinux
sudo pacman -S \
  nodejs \
  npm

# macos
brew install
  node.js \
  npm

npm install -g neovim

" install coc
Plug "https://github.com/neoclide/coc.nvim", {'branch': 'release'}

" install coc languages
Plug 'https://github.com/neoclide/coc-tsserver', {'do': 'yarn install --frozen-lockfile'}
CocInstall coc-pyright

NOTE:

Officially, installing servers can be done from vim-plug, but I have not had success with this.

CocInstall works every time. It's probably best to check for files on disk.

Configuration

Keybindings

coc.nvim does not provide function calls, they direct you to bind hotkeys instead.
