# Open a new kitty window in the working directory of the focused terminal.
#
# Umbriel's spawn action hands the new process Umbriel's own working
# directory, so ask the focused kitty instance over its remote control socket
# to open an OS window with --cwd=current instead. Requires in kitty.conf:
#
#     allow_remote_control yes
#     listen_on unix:/tmp/umbriel-kitty
#
# Each instance then listens on /tmp/umbriel-kitty-<pid>. Falls back to a
# plain kitty launch when no instance is listening, for example on the first
# terminal of a session or while focus is outside kitty.
#
# Usage: bind the compositor terminal keybind to this script.
