neovim-ctrl

• Changelog

neovim-ctrl is a program to find and interact with a Neovim instance running in a particular terminal. It works with Neovim 0.9.0 and higher.

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.

# 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

# Send Ctrl-w-h to the Neovim on /dev/pts/7:
$ 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 $?
> 0

$ nvim-ctrl change-window /dev/pts/7 "${ctrlw}h"
> Error: nothing changed
# Exit code 1 means that no change happened.
$ echo $?
> 1
