My notes on nvim.

tl;dr: Prefer the tarball to snap or default package manager.

The regular apt-get repo is too out-of-date. When 0.9.5 was stable, Ubuntu 20.04 was providing 0.3 or 0.4.

I could use snap on my work (Ubuntu) and personal frame.work laptop computers to get 0.9.5. (However, GitHub recommends against snap for gh, so maybe snap is problematic.)

sudo snap install nvim --classic
ln -s /snap/bin/nvim $HOME/.local/bin/nvim

But in WSL2, although I had snap, it didn't work, so I downloaded the tarball. Then I extracted it into $HOME/.local/bin/.

cd ~/.local/bin/
tar -xvf nvim-linux64.tar.gz
ln -s nvim-linux64/bin/nvim nvim

You need Node for the Copilot plugin (Getting Started instructions). It also works with Vim 9.0.0.0185+.

1. Install Node.
2. Get nvim (see above)
3. Install plugin (used –filter=blob:none)
   1. git clone --filter=blob:none https://github.com/github/copilot.vim.git ~/.config/nvim/pack/github/start/copilot.vim
4. read docs.
