Project Introduction

Motivation

Vim codebase is a really bad one according to several people.

Contributions are hard.

Installation

From Packages

# Ubuntu

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

# OSX

brew tap neovim/neovim
brew install --HEAD neovim

Specific Dependency

# Python Module
sudo pip2 install neovim

# Clipboard (on Linux, depends on distro)
sudo apt-get install xsel

Linking configuration

# The easy way

ln -s ~/.vimrc ~/.nvimrc
ln -s ~/.vim ~/.nvim

And it works !

Configuration

Same config file as is

• It works (unless you're doing obscure stuff) !
• Neovim ignores most obsolete settings

Same config file modified

" Conditionals

if !has('nvim')
  set ttymouse=xterm2
endif

if has('nvim')
  tnoremap <Esc> <C-\><C-n>
endif

Partials

" load specific

if has('nvim')
  source ./nvim_only
else
  source ./vim_only
endif

" common config

...

Specific .nvimrc

• File will be simpler
• e.g. you don't need feature existence test
• Need to maintain both
