  #
  # Script to download an artist dataset from musicbrainz and save it as json
  # files.
  #
  # How to use:
  #   ./dowload-dataset.py <file>
  #
  # Where the file must have an artist name per line.
  # The script then queries the musicbrainz API for a search with each artist name
  # and then downloads the information on all the artists returned by the search
  # query.
  
  import json
  import musicbrainzngs
  import sys
  
  # Get input file
  if len(sys.argv) != 2:
      print("missing file with bands name", file=sys.stderr)
      exit(1)
  f = open(sys.argv[1], 'r')
  
  # Set musicbrainz api library
  musicbrainzngs.set_useragent("data downloading app", "0.1", "http://alemedeiros.sdf.org")
  
  
  for l in f.read().splitlines():
      # Query for artist info
      res = musicbrainzngs.search_artists(l)
  
      # Get the data for all the artists returned
      for art in res['artist-list']:
          art_data = musicbrainzngs.get_artist_by_id(art['id'], includes=['aliases', 'tags', 'ratings'])
  
          # Save the data for each artist in a different json file
          jf = open(art['id'] + '.json', 'w')
          jf.write(json.dumps(art_data['artist'], sort_keys=True, indent=2))
