Neovim Setting up the basics

General Setings

To include some basics in your config first create a directory called general and a file called settings.vim

mkdir ~/.config/nvim/general touch ~/.config/nvim/general/settings.vim

Here is every general setting I use with a brief explanation:

Add the following to settings.vim

" set leader key let g:mapleader = "\<Space>" syntax enable " Enables syntax highlighing set hidden " Required to keep multiple buffers open multiple buffers set nowrap " Display long lines as just one line set encoding=utf-8 " The encoding displayed set pumheight=10 " Makes popup menu smaller set fileencoding=utf-8 " The encoding written to file set ruler " Show the cursor position all the time set cmdheight=2 " More space for displaying messages set iskeyword+=- " treat dash separated words as a word text object" set mouse=a " Enable your mouse set splitbelow " Horizontal splits will automatically be below set splitright " Vertical splits will automatically be to the right set t_Co=256 " Support 256 colors set conceallevel=0 " So that I can see `` in markdown files set tabstop=2 " Insert 2 spaces for a tab set shiftwidth=2 " Change the number of space characters inserted for indentation set smarttab " Makes tabbing smarter will realize you have 2 vs 4 set expandtab " Converts tabs to spaces set smartindent " Makes indenting smart set autoindent " Good auto indent set laststatus=0 " Always display the status line set number " Line numbers set cursorline " Enable highlighting of the current line set background=dark " tell vim what the background color looks like set showtabline=2 " Always show tabs set noshowmode " We don't need to see things like -- INSERT -- anymore set nobackup " This is recommended by coc set nowritebackup " This is recommended by coc set updatetime=300 " Faster completion set timeoutlen=500 " By default timeoutlen is 1000 ms set formatoptions-=cro " Stop newline continution of comments set clipboard=unnamedplus " Copy paste between vim and everything else "set autochdir " Your working directory will always be the same as your working directory au! BufWritePost $MYVIMRC source % " auto source when writing to init.vm alternatively you can run :source $MYVIMRC " You can't stop me cmap w!! w !sudo tee %

Source in init.vim

source $HOME/.config/nvim/general/settings.vim

Mapping new keys

Again we'll create a directory called keys and and a file called mappings.vim

mkdir ~/.config/nvim/keys touch ~/.config/nvim/keys/mappings.vim

Add the following to mappings.vim:

" Better nav for omnicomplete inoremap <expr> <c-j> ("\<C-n>") inoremap <expr> <c-k> ("\<C-p>") " Use alt + hjkl to resize windows nnoremap <M-j> :resize -2<CR> nnoremap <M-k> :resize +2<CR> nnoremap <M-h> :vertical resize -2<CR> nnoremap <M-l> :vertical resize +2<CR> " I hate escape more than anything else inoremap jk <Esc> inoremap kj <Esc> " Easy CAPS inoremap <c-u> <ESC>viwUi nnoremap <c-u> viwU<Esc> " TAB in general mode will move to text buffer nnoremap <TAB> :bnext<CR> " SHIFT-TAB will go back nnoremap <S-TAB> :bprevious<CR> " Alternate way to save nnoremap <C-s> :w<CR> " Alternate way to quit nnoremap <C-Q> :wq!<CR> " Use control-c instead of escape nnoremap <C-c> <Esc> " <TAB>: completion. inoremap <expr><TAB> pumvisible() ?

Source in init.vim

source $HOME/.config/nvim/keys/mappings.vim

Get healthy

Open nvim and enter the following:

:checkhealth

You'll probably notice you don't have support for copy/paste also that python and node haven't been setup

So let's fix that

First we'll fix copy/paste

• On mac pbcopy should be builtin

• On Ubuntu

  sudo apt install xsel

• On Arch Linux

  sudo pacman -S xsel

Next we need to install python support (node is optional)

• Neovim python support

  pip install pynvim

• Neovim node support

  npm i -g neovim

Note

If you use virtual environments I highly suggest putting these varibles in your config

I recommend putting this in paths.vim in the general directory

let g:python3_host_prog = expand("<path to python with pynvim installed>") let g:python3_host_prog = expand("~/.miniconda/envs/neovim/bin/python3.8") " <- example let g:node_host_prog = expand("<path to node with neovim installed>") let g:node_host_prog = expand("~/.nvm/versions/node/v12.16.1/bin/node") " <- example

Run checkhealth again and you should now see the requirements are met
