If invoked outside of Neovim, nvr [options] simply invokes nvim [options]. If invoked from within Neovim (such as in a terminal buffer), nvr [options] will open a new, horizontally split window in the existing Neovim session.

nvr is intended to be used as your $EDITOR or $GIT_EDITOR. When you invoke commands like git commit, git rebase --interactive, etc. within a Neovim terminal buffer, a new split window appears in the existing Neovim session (instead of in a nested Neovim session). After writing a commit message, save and exit the window with, e.g., :x. That will delete the buffer and signal to git commit that you're finished authoring your commit message.

nvr can be invoked with multiple files. You must save and exit all buffers opened by nvr before the process will exit and return control to your shell.

nvr supports the +N / +command options as they work in Vim/Neovim.

nvr supports the -q option as it works in Vim/Neovim and thus is usable via commands like git jump grep.
