Neovim Setup

A repo that I'm using to learn vim/neovim.

Just formatted this README and added this line via neovim. Massive flex :O

You can find my 2 configs in coc version and lsp version

Some basic Navigation

Press i to enter insert mode.

Press escape to exit current mode.

This lets you actually make changes to your files. Until then it's all read-only. Good to read through some code without worrying about accidental changes.

Creating and opening files:

# while in the directory you want to work in
nvim nameoffile.extension

Creates or opens the file specified depending on it's existence on disk.

Opening entire director:

nvim .

Opens and displays a file browser that you can naviagate through. Press enter to open file. Neat out-of-the-box feature.

Editting the Config

While in your default working directory. Create/Access the .config folder. This usually already exists so beware.

mkdir .config
cd .config/

Make a nvim directory:

mkdir nvim

Create neovim config file:

nvim init.vim

Sample Config

My current config will be added to this repo

:set number
:set relativenumber
:set autoindent
:set tabstop=4
:set shiftwidth=4
:set smarttab
:set softtabstop=4
:set mouse=a

Install a Plug-in Manager

I am using vim-plug for this. Follow install instructions from there.

Setting up vim-plug requires adding the following to the init.vim file:

call plug#begin()
" all your plugins...
Plug 'url to your plugin'
call plug#end()

Also install exuberant ctags

brew install ctags

Installing the Plugins (One time only)

Inside your nvim instance run the following in command mode:

:PlugInstall

Your plugins are now installed!

Deleting plugins:

Remove the Plug '' entry from the init.vim file.

Run :PlugClean.

Install coc

For autocompletions.

After adding the Plug config:

Plugin 'neoclide/coc.nvim'

Go to your plugged folder.

On Mac: ~/.local/share/nvim/plugged.

On Linux: ~/.config/nvim/plugged.

cd coc.vim/
yarn

This installs all dependencies. Takes a while.

Installing Language Servers

Install using:

:CocInstall name-of-lsp

Python: coc-pyright.
JSON: coc-json.
Markdown: coc-markdownlint.
JS/TS: coc-tsserver.
HTML: coc-html.
Java: coc-java.
CSS: coc-css.
Dart: coc-flutter.
Bash: coc-sh.
prettier: coc-prettier.

Integrity Check

:checkhealth

Useful keyboard shortcuts

Undo/Redo

Use :u and :r respectively.

Search and Highlight

In command mode. Press / to enter search. Now type a regex pattern you would like to search.

Clear the selections by using :noh.

Copy/Paste/Select

To select any text, you must enter visual mode. Press v in normal mode for this.

Use arrow keys to expand the selection.
d Deletes the selection.
y "yank"/copy the selection.
p Paste the selection.
Search by using these 4 in conjuntion on the selected text: y q / p
r Replace selection with text you will now type.

Copy/Paste Across Terminals

Use: " + y and " + p from visual mode.

For Tiling

Ctrl W S (upper case) for horizontal splitting
Ctrl W v (lower case) for vertical splitting
Ctrl W Q to close one
Ctrl W Ctrl+W to switch between windows
Ctrl W J (x or K, H, L) to switch to adjacent window (intuitively up, down, left, right)

Loading Lua Scripts

Create a lua directory under .config/nvim/.
Create another subdirectory under lua. Use your name for example.
Write all your scripts here. Ex: options.lua.
At the nvim/lua directory level create a config.lua and inside that add references to all subdirectory contained lua scripts with:

require "example_subdir.option"

In your init.vim load the script with:

lua require('config')

LSP Instead of coc

After tinkering with coc, which is easier to get started with, I realized I need greater granular control over my configs while also keeping them light weight. So I'm switching to the native LSP.

Add the nvim-lspconfig plugin.

Plug 'neovim/nvim-lspconfig'

Installing LSPs

Python: yarn global add pyright
JS/TS: yarn global add typescript typescript-language-server
