Neovim setup for Python

Neovim installation

add-apt-repository ppa:neovim-ppa/unstable

sudo apt install -y neovim

Check if Neovim is installed successfully.

nvim -v

Neovim is a strong editor with abundant plugins, but it doesn't have a plugin manager by default. vim-plug is a pluggable plugin manager for nvim.

vim-plug installation

curl -fLo ~/.local/share/nvim/site/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

plug.vim is stored in path ~/.local/share/nvim/site/autoload/, you can stored the file in a customized directory.

Initialize nvim configuration file

Go to path /root/.config/, and then create a configuration directory nvim for nvim. And create init.vim.

call plug#begin('~/.local/share/nvim/plugged')
call plug#end()

All plugins should be put between the two line start with call.

vim-plug usage

Run command in the nvim mode

• :PlugInstall
• :PlugUpdate
• :PlugClean
• :PlugStatus
• :PlugUpgrade

Stop a plugin temporarily

Plug 'foo/bar', { 'on': [] }

Auto-complete plugin(deoplete)

Add deoplete to init.vim like this:

call plug#begin('~/.local/share/nvim/plugged')

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

call plug#end()

Add you should also configure it below

let g:deoplete#enable_at_startup = 1

But that's not all, we have to add different source through jedi

# pynvim is required, you may also need to install `jedi` as well

pip install pynvim
pip install jedi

Install deoplete-jedi

Plug 'zchee/deoplete-jedi'

Now restart nvim, the auto-complete function should work properly.

Use shortcut ctrl + n and ctrl + p to navigate up and down in autocomplete pop-ups
