# Purpose: The purpose of this script is to accept a file name then find a tmux
# pane that is currently running either vim or neovim and tell that pane to open
# up the file. This script is meant to be used with a fuzzy find such as fzf so
# that you can use an external fuzzy finder but still integrate it with vim
#
# Set options:
# e: Stop script if command fails
# u: Stop script if unset variable is referenced
# x: Debug, print commands as they are executed
# set -eu
# Immutable globals
