AKA Ironic Repositioning System

A music scraper that understands your metadata needs.

Installation

1. Download the latest release for your platform here
2. Create a .yaml config file somewhere on your system
3. Copy the following into it

   binary_directory: ~/.irs/bin
   music_directory: ~/Music
   client_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   client_secret: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   single_folder_playlist:
       enabled: true
       retain_playlist_order: true
       overwrite_album: false
   

4. Set the environment variable IRS_CONFIG_LOCATION pointing to that file
5. Go to https://developer.spotify.com/dashboard/
6. Log in or create an account
7. Click CREATE A CLIENT ID
8. Enter all necessary info, true or false, continue
9. Find your client key and client secret
10. Copy them into where all the X's are in your config file from above

You should be good to go! Run the file from your command line to get help on usage or keep reading!

Optionally From Source

Or if you're one of those cool people who compiles from source

1. Install crystal-lang (https://crystal-lang.org/install/)
2. Clone it (git clone https://github.com/cooperhammond/irs)
3. CD it (cd irs)
4. Build it (shards build)

Usage

How it works

At it's core irs downloads individual songs. It does this by interfacing with the Spotify API, grabbing metadata, and then searching Youtube for a video containing the song's audio. It will download the video using youtube-dl, extract the audio using ffmpeg, and then pack the audio and metadata together into an MP3.

From the core, it has been extended to download the index of albums and playlists through the spotify API, and then iteratively use the method above for downloading each song.

It used to be in python, but

1. I wasn't a fan of python's limited ability to distribute standalone binaries
2. It was a clusterfuck of code that I made when I was little and I wanted to refine it
3. crystal-lang made some promises and I was interested in seeing how well it did (verdict: if you're building high-level tools you want to run quickly and distribute, it's a joy to work in)
