Use github.com/will/bgwinch.nvim instead since neovim 0.7

autobg.nvim

This plugin syncs the background option in neovim to match the macOS appearance.

It assumes that if you're on a mac you have swiftc installed from xcode commandline tools or something, and compiles a very small program that listens for appearance changes and notifies neovim.

It also depends on plenary.nvim.

Packer

use {
  "will/autobg.nvim",
  config = function()
    require("autobg").setup()
  end,
}

Todo

I couldn't figure out a good way to ensure that the helper program exits in all cases when neovim exists, and opened an issue about that. In the meantime, the helper program prints to stdout once a minute, and will get killed with SIGPIPE if the parent neovim process is gone.
