Neovim Ruby

Ruby support for Neovim.

Installation

Add this line to your application's Gemfile:

gem "neovim"

And then execute:

bundle

Or install it yourself as:

gem install neovim

Usage

Neovim supports the --listen option for specifying an address to serve its RPC API. To connect to Neovim over a Unix socket, start it up like this:

$ nvim --listen /tmp/nvim.sock

You can then connect to that socket path to get a Neovim::Client:

require "neovim"
client = Neovim.attach_unix("/tmp/nvim.sock")

Refer to the Neovim docs for other ways to connect to nvim, and the Neovim::Client docs for a summary of the client interface.

Remote Modules

Remote modules allow users to define custom handlers in Ruby. To implement a remote module:

• Define your handlers in a plain Ruby script that imports neovim
• Spawn the script from lua using jobstart
• Define commands in lua using nvim_create_user_command that route to the job's channel ID

For usage examples, see:

• example_remote_module.rb
• example_remote_module.lua
• remote_module_spec.vim

Note: Remote modules are a replacement for the deprecated "remote plugin" architecture. See https://github.com/neovim/neovim/issues/27949 for details.

Vim Plugin Support

The Neovim gem also acts as a compatibility layer for Ruby plugins written for vim. The :ruby, :rubyfile, and :rubydo commands are intended to match their original behavior, and their documentation can be found here.
