Picture-download/file-rename program
# Mac gives a 'cross-device link error' when using File.rename

# to a folder on the computer, 'camera', and then need to be renamed and moved
# to a pictures folder on the desktop.

2. Build your own playlists.
def shuffle array
x = 0
track_number = 0
number_songs = 0
playlist = [ ]
number_songs = array.length
while x < number_songs
track_number = rand(number_songs)
if array[track_number] != ''
playlist.push array[track_number]
array[track_number] = ''
x = x + 1
else
end
end
filename = 'Desktop/playlist.m3u'
File.open filename, 'w' do |f|
f.puts playlist
end
end
tracks = Dir['Desktop/music/**/*.{ogg,mp3,m4a}']
shuffle tracks
3. Mixed random better playlist.
# music_shuffle tries to minimize clumping at the beginning of playlist,
# does not generate a perfectly mixed up playlist
# just less clumpy
def music_shuffle array
x = 0
track_number = 0
number_songs = 0
playlist = [ ]
full_song_name = [ ]
album_on_deck = ''
previous_album = ''
number_songs = array.length
while x < number_songs
track_number = rand(number_songs)
full_song_name = array[track_number].split'/'
album_on_deck = full_song_name[2]
if album_on_deck != previous_album
if array[track_number] != ''
playlist.push array[track_number]
array[track_number] = ''
x = x + 1
else
end
previous_album = album_on_deck
else
end
end
filename = 'Desktop/playlist.m3u'
File.open filename, 'w' do |f|
f.puts playlist
end
end
tracks = Dir['Desktop/music/**/*.{ogg,mp3,m4a}']
music_shuffle tracks
