Hi guys, this is my first post and I will help to install Neovim for MacOS. In this case, the plugins to install will be mostly backend development (Python and Go).

Why Neovim? :

Personally, my primary motivation to try out Neovim was:

  • Reducing load on my machine.
  • Have the experience of using Vim/NeoVim as my IDE.
  • To be curios about why Vim/Neovim is so special.

What is Neovim?:

Neovim is a project that seeks to aggressively refactor Vim source code to achieve the following goals:

  • Simplify maintenance to improve the speed that bug fixes and features get merged.
  • Split the work among multiple developers.
  • Enable the implementation of new/modern user interfaces without any modifications to the core source.
  • Improve the extensibility power with a new plugin architecture based on coprocesses. Plugins will be written in any programming language without any explicit support from the editor.

Let's start:

Setup: 

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  • Copy and paste this command to install neovim 
brew install neovim
  • Then go to this file <username>/.config/nvim/init.vim
    • If the files/directories don't exist, just create them manually.
  • Open the file and set your config file:
    • Use nvim init.vim on the console, to open the config file or any text editor.
    • You can use the configurations below: 
" Options
set clipboard=unnamedplus " Enables the clipboard between Vim/Neovim and other applications.
set completeopt=noinsert,menuone,noselect " Modifies the auto-complete menu to behave more like an IDE.
set cursorline " Highlights the current line in the editor
set hidden " Hide unused buffers
set autoindent " Indent a new line
set inccommand=split " Show replacements in a split screen
set mouse=a " Allow to use the mouse in the editor
set number " Shows the line numbers
set splitbelow splitright " Change the split screen behavior
set title " Show file title
set wildmenu " Show a more advance menu
set cc=80 " Show at 80 column a border for good code style
filetype plugin indent on   " Allow auto-indenting depending on file type
syntax on
set spell " enable spell check (may need to download language package)
set ttyfast " Speed up scrolling in Vim
  • If the configuration is correct, when you open a file it should be looking like this.

Setup init.vim

  • The next step we need to install a PlugIn manager. In this case, we are using vim-plug, this is the link.

    https://github.com/junegunn/vim-plug

    • Because we are using neovim we need to use this command 
sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
           https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
    ```
{% endraw %}

- After installing vim-plug, is necessary to add these couple of lines on init.vim, so we can use :PlugInstall command.
 - The Plug command is to install the plugins we want to install in our configuration.
{% raw %}

```bash
call plug#begin(has('nvim') ? stdpath('data') . '/plugged' : '~/.vim/plugged')
Plug 'Example'
call plug#end()
  • List of plugins: 
Plug 'morhetz/gruvbox'
Plug 'vim-airline/vim-airline'
Plug 'vim-airline/vim-airline-themes'
Plug 'ryanoasis/vim-devicons'
Plug 'scrooloose/nerdtree'
Plug 'scrooloose/nerdcommenter'
Plug 'sheerun/vim-polyglot'
Plug 'jiangmiao/auto-pairs'
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'tpope/vim-fugitive'
  • After the line "Call plug#end()" you need to add a configuration lines to use the theme, the airline extension and the NERDTree 
colorscheme gruvbox
let g:bargreybars_auto=0
let g:airline_solorized_bg='dark'
let g:airline_powerline_fonts=1
let g:airline#extension#tabline#enable=1
let g:airline#extension#tabline#left_sep=' '
let g:airline#extension#tabline#left_alt_sep='|'
let g:airline#extension#tabline#formatter='unique_tail'
let NERDTreeQuitOnOpen=1
  • After you install the Plugins, your neovim configuration should be looking like this:

  • If you don't want to use "Gruvbox" as you main theme you can take a look to this page: Vim Themes
