Rico's Neovim + Coc settings

👋 Hey there, here's my setup on how I use coc.nvim to make my Vim work like an IDE.

I've been VSCode, Atom, Sublime, and other modern editors. They are fantastic! I love how I get automatic type hints, amazing auto-complete, inline documentation, and many things that Vim users may consider to be frivolous luxuries.

They're no Vim, though. VSCode's Vim emulation can be a bit slow (try doing 9j on vscode-vim, and try it on Vim itself). They also take a lot of memory, which can be too much for 4GB/8GB laptops.

Since coc.nvim came around, there's no need to compromise anymore. You can get IDE-like features in Vim, and here's how I did it!

Install Vim (and friends)

You need neovim (or vim 8.1+), nodejs and yarn. Coc's internals runs on Node.js.

I suggest using vim-plug to manage your dependencies.

Copy from the files here

The files in this repo are things you can merge into your Vim/Neovim configuration.

If you're using Vim instead of Neovim, take what's in init.vim and place it in ~/.vimrc, and the config folder is ~/.vim instead of ~/.config/nvim.

Also see

Many of the configuration are lifted from almost-verbatim from Coc documentation. I highly recommend checking those out too.

Key bindings

See after/plugin/coc.vim for a full list of key bindings. Below are some of the features that I find to be most useful:

Key	Description
gh — Show hint/documentation Shows a hint for whatever's on the cursor. This means type definitions, JSDoc comments, and documentation (when available). Similar to VSCode's mouse over functionality.
space c r — Rename symbol Rename whatever is on the cursor. Similar to VSCode's Rename Symbol command (F2).
ctrl-n — Code completion Code completion just happens. ctrl-n and ctrl-p are default Vim key bindings for browsing through code completions.
space-cc-prettier — Prettier Prettier formatting happens on every save, automatically! You can also trigger it manually via invoking Coc commands via space-c-c.
space c c — Show available commands Fix tslint problems automatically, run Prettier manually, auto-fix eslint, and more.	-
space c x — Enable/disable extensions If you don't need tsserver in your current project, you can temporarily disable them.	-
space c l — List errors When you find errors, use this to shown them all	-
