# Title: Bash autocompletion for rescan-library
# Project: jellystack
# Purpose: Make it easy to choose a jellyfin library to rescan
# History:
# Usage:
# dot-source it and then alias the script:
# . /mnt/public/Support/Programs/jellyfin/autocmplete-rescan.bash
# alias rescan-library=/mnt/public/Support/Programs/jellyfin/rescan-library.sh
# Reference:
# 1. https://stackoverflow.com/questions/44453510/how-to-autocomplete-a-bash-commandline-with-file-paths-from-a-specific-directory/47799826#47799826
# 2. https://stackoverflow.com/questions/1146098/properly-handling-spaces-and-quotes-in-bash-completion
# Improve:
# Dependencies:
# password stored in ~/.jellyfin.password
# jellystack.py frontend and jellystack_lib.py
