These are easy to follow instructions, adapt them for your needs 😉.

1. (IMPORTANT) Create a directory ~/iPod
2. (IMPORTANT) Mount your iPod in /ipod
3. Place all of your songs/podcasts into ~/iPod/music

• Each (first level) directory/folder is one playlist

4. Run this script

WARNING: if you are in a case sensitive filesystem (very likely if you are using linux) the case of the directories matter.

#!/bin/bash

# I am not the author of this script.
# Unfortunately I don't remember where I copied from.

Errata from my last talk:

1. Crystal lang does not have metaprogramming, but they have macros: https://crystal-lang.org/docs/syntax_and_semantics/macros.html , and there is some tricks here https://github.com/crystal-lang/crystal/wiki/MetaProgramming-Help :)
2. About arguments (or array of arguments) the official documentation talks about that: https://crystal-lang.org/docs/syntax_and_semantics/default_values_named_arguments_splats_tuples_and_overloading.html
3. youtube-dl is not a binary for two OS, it is at the end a zip file with python code inside a python file, you can see the content with this (I'm using Linux):

wget https://yt-dl.org/downloads/latest/youtube-dl -O- | sed "1d" | gunzip | less
