neovim-ctrl is a program to find and interact with a Neovim instance running in a particular terminal.

The program supports two commands: - find-socket to discover the Unix domain socket of a running Neovim - change-window to change the currently selected window/split based on a key sequence

Usage

The program requires the TTY for which to find the (first) running Neovim process the first argument.

```bash

Find the path to the Unix domain socket for a nvim process on TTY

/dev/pts/3:

$ nvim-ctrl find-socket /dev/pts/3

/tmp/nvimfMfu99/0 ```

```bash

Send Ctrl-w-h to the Neovim on /dev/pts/3:

$ ctrlw=$(echo -n -e "\x17") $ nvim-ctrl change-window /dev/pts/7 "${ctrlw}h"

Exit code 0 indicates that the window was actually changed.

$ echo $?

$ nvim-ctrl change-window /dev/pts/7 "${ctrlw}h"

Error: nothing changed

Exit code 1 means that no change happened.

$ echo $?
