Next generation vim support for atom

What is this?

This is a work in progress branch that shows how to make Atom talk to Neovim.

What's new?

I've update everything to work with the version in master of Neovim

On the Atom side I've tested it with version 0.175 and 0.184 and seems to work fine.

How do you run this?

Install, run, and quit Atom to make sure .atom exists

Install vim-mode

$ cd .atom/packages
$ git clone https://github.com/carlosdcastillo/vim-mode.git
$ cd vim-mode
$ apm install # install dependencies

Create a folder for the socket

$ mkdir -p /tmp/neovim

Run Neovim, pointing it to the socket

$ NVIM_LISTEN_ADDRESS=/tmp/neovim/neovim581 nvim -T abstract_ui

What do you want to do with this?

This project aims to:

• Bring real vim bindings to Atom.
• Give the abstract-ui neovim functionality a work out and find issues using the msgpack api.
• Eventually build an editor that I would find useful. At the current state it is pre-alpha.

See it in action

and this is an older video using the old redraw-events branch (from mid 2014):

Things TO DO

• Handle Atom-centric text editing actions, i.e., situations like the user searching and replacing in Atom by hitting Cmd-F
• Make the client use less CPU. It currently uses a lot of CPU, this could be a consequence of my limited CoffeeScript experience.

Configuring Atom

To make sure that hjkl get repeated like (Vim and Neovim) on Mac you will need to run (from the command line):

defaults write com.github.atom ApplePressAndHoldEnabled -bool false
