Install Neovim

Test a new AppImage in this repo

Use this when you want to validate a new Neovim release in the current worktree before replacing /usr/bin/nvim.

cd ~/.config/neovim-config.git/v0.12
curl --fail --location \
  --output nvim-appimage \
  https://github.com/neovim/neovim/releases/download/v0.12.1/nvim-linux-x86_64.appimage
chmod +x nvim-appimage
./nvim --version
./nvim-init
./nvim --headless "+checkhealth" +qa

The repo-local ./nvim and ./nvim-init wrappers prefer ./nvim-appimage when it exists and otherwise fall back to /usr/bin/nvim.

Use ./nvim-init --reset only when you want to remove the app-local data and state directories for that worktree before rebuilding them.

Keep a standalone AppImage binary

Use this when you want an explicit Neovim binary outside the repo wrappers.

export nvim_version="v0.12.1"
mkdir -p ~/downloads/nvim/"${nvim_version}"
cd ~/downloads/nvim/"${nvim_version}"
curl --fail --location \
  --output nvim-linux-x86_64.appimage \
  "https://github.com/neovim/neovim/releases/download/${nvim_version}/nvim-linux-x86_64.appimage"
sha256sum nvim-linux-x86_64.appimage
chmod +x nvim-linux-x86_64.appimage
install -m 0755 nvim-linux-x86_64.appimage ~/.local/bin/nvim-v0.12.1

This keeps the binary versioned and explicit. Use Isolated Install when you want to pair that binary with a separate NVIM_APPNAME config.
