Adding your own sources

To add your own source, create a new .cs file in the TrackSources folder with a class that returns a TrackData list. This list should contain tracks with a title, artist, and a hash (used for filtering out duplicates) (see example). A 'track' in this list with the parameter track.IsAlbum set to true will be treated as an album when searching on Spotify. In this case all the tracks in the album will be added to the playlist.

Example:

namespace SpotifyReleaseScavenger.TrackSources
{
  public class newSource_Source1: IScavenge
  {
    public List<TrackData> GetTracks()
    {
      List<TrackData> trackData = new List<TrackData>();
      
      /* // Your custom scrape code:
       *
       * // Get track title and artist from source
       * //...
       * 
       * // Create track
       * TrackData track = new TrackData();
       * track.Title = //Scraped title
       * track.Artist = //Scraped artist
       * 
       * // Set hash
       * track.Hash = Convert.ToBase64String(SHA256.HashData(Encoding.UTF8.GetBytes($"{track.Artist}{track.Title}")));
       * 
       * // Add track to list
       * trackData.Add(track);
       */
      
      return trackData;
    }
  }
}

In the appsettings.json, add the Spotify playlist ID:

{
 "SpotifyPlaylistId": {
   "NewPlaylist": "SPOTIFY_PLAYLIST_ID"
 }
}

In the Run() method in the Program.cs file, add your new playlist like so:

// newPlaylist
List<IScavenge> newPlaylistSources = new()
{
    new newSource_Source1()
};
string newPlaylistId = configurationBuilder.GetSection("SpotifyPlaylistId:NewPlaylist").Value;
PlaylistData newPlaylist = new(newPlaylistId, newPlaylistSources);

and add the newly created playlist to the list of playlists:

// Add playlists to list
List<PlaylistData> playlists = new()
{
  ...
  newPlaylist
};
