populate

A simple command line app to populate music files.

What exactly is this?

This is an app that I wrote because it was useful to me, but I hope it can be useful to other people to. The idea is to take a file specifying a library of music (song name, artist, where to get it etc) the app fetches the song and splits it based on provided time stamps if necessary.

For example, a file like:

[[source]]
  name = "Gattsu"
  artist = "Susume Hirasawa"
  path = "Susume Hirasawa/"
  url = "https://www.youtube.com/watch?v=_isSnrC2__A"
  timestamps = ["0:00", "1:00"]
  namestamps = ["first", "second"]

specifies how to get an album named "Gattsu" by an artist named "Susume Hirasawa", by fetching it from a url and then unpacking it into the songs that compose it in a certain directory.

The app takes a bunch of sources like these and downloads and unpacks them all.

Building

With Stack Installed on System

This program relies on having the cli applications youtube-dl and ffmpeg available. taglib_c is also needed for adding metadata to the audio files. On my system (ubuntu) acquiring these depencies looks like this:

sudo apt-get install ffmpeg
sudo apt-get install youtube-dl
sudo apt-get install libtagc0-dev

Feel free to submit corresponding instructions for your platform :)

With stack, building and installing the program looks like this:

stack install

With Nix

Assuming you have a nix installation in your system, building and running the project is done like the following:

$(nix-build default.nix)/bin/populate mysrc.toml
