NeoVim quick starter guide with python autocomplete. On May 21, 2016 by Mitesh Shah

So there’s no simple guide available online which just gets me running really quickly. Most of them are either too detailed, or too obscure. So I decided to post my own.

Install neovim (guide here). On ubuntu it is:

sudo add-apt-repository ppa:neovim-ppa/unstable sudo apt-get update sudo apt-get install neovim

To use the python plugins install neovim python package:

sudo pip3 install neovim #sudo pip2 install neovim

Setup the NeoVim config files.

mkdir -p ${ XDG_CONFIG_HOME : = $HOME /.config } mkdir $XDG_CONFIG_HOME /nvim # You can link .vim here, but I'm starting from scratch. touch $XDG_CONFIG_HOME /nvim/init.vim

Now we install a plugin manager, dein.vim:

cd /tmp && \ curl https://raw.githubusercontent.com/Shougo/dein.vim/master/bin/installer.sh > installer.sh && \ mkdir -p $HOME /.random && \ sh ./installer.sh $HOME /.random || \ echo "Failed."

The installer will throw a wall of text and ask you to copy-pasta it in your init.vim file.

Now we need to let NeoVim know where our python binaries are located.

let g:python_host_prog = '/usr/bin/python' let g:python3_host_prog = '/usr/bin/python3'

Uncomment the following lines in your init.vim file, which installs plugins on startup:

if dein#check_install () call dein#install () endif

Now to install autocomplete for python. We will use deoplete.nvim with deoplete-jedi as source.

# First install jedi sudo pip3 install jedi # Also install yapf for formatting sudo pip3 install yapf

Now add these lines to your init.vim :

call dein#add ( 'Shougo/deoplete.nvim' ) call deoplete#enable () autocmd FileType python nnoremap < leader > y : 0 , $ ! yapf < Cr > autocmd CompleteDone * pclose " To close preview window of deoplete automagically

Feel free to checkout my NeoVim config on github.
