# Dep: youtube-dl, mpv, notify-send, dmenu
# This script will be a wrapper of the Go programming using handling pipe data.
# The idea is that this will allow keep the program to stick to doing one thing.
# While it is possible to use pipes in Golang, I find this approach to be better
# for integration into a Linux system. However, this could be changed in the
# future and integrated into the Go program. We'll see. THIS IS AN EXAMPLE.

# Set timeout to 4s
alias notify-send="notify-send -t 4000"
# Set dmenu prompt
alias dmenu="dmenu -p 'play >' -l 10"

add() {
	yt-cli -add $1 && notify-send "YouTube CLI" "Added $1"

	# todo: error check
	id=$(yt-cli -list | dmenu)
	# remove [date] and (id) for title
	title=${id#\[*\]}
	title=${title%(*)}
	# get ID from title
	id=${id#*(}
	id=${id%)}
	mpv "https://youtube.com/watch?v=$id" > /dev/null < /dev/null &
	notify-send "YouTube CLI" "Playing $title"
