RubyCue is a Ruby interface for parsing and accessing cuesheet data.
require 'rubycue' cuesheet = RubyCue::Cuesheet.new(File.read("cuesheet.cue")) cuesheet.parse! cuesheet.songs.each do |song| puts "#{song[:performer]} - #{song[:title]} at #{song[:index]}" end
RubyCue will also calculate song durations. In order to calculate the last song’s duration, you must pass the optional track duration (in seconds) for the entire file.
cuesheet = RubyCue::Cuesheet.new(File.read("cuesheet.cue"), 7143)
After a cuesheet is instantiated, you can pass a current track position, and the cuesheet will return which song is currently playing at that position:
# with seconds
cuesheet.position(4352)
=> {:index=>#<RubyCue::Index:0x101025240 @seconds=7, @minutes=71, @frames=31>, :track=>32, :performer=>"Netsky", :title=>"Iron Heart", :duration=>#<RubyCue::Index:0x10100f2d8 @seconds=55, @minutes=2, @frames=38>}
# with an array [minutes, seconds, frames]
cuesheet.position([43, 23, 45])
=> {:index=>#<RubyCue::Index:0x101027590 @seconds=27, @minutes=39, @frames=57>, :track=>19, :performer=>"Legion feat. Adam Wright", :title=>"Both Sides", :duration=>#<RubyCue::Index:0x101013130 @seconds=45, @minutes=4, @frames=13>}
Index objects are a time representation of the position in a track. They are represented with fields [minutes, seconds, frames]. There are 75 frames in each second. You can access the values of the index object like so:
index = Index.new([30, 23, 73]) index.minutes => 30 index.seconds => 23 index.frames => 73 index.to_i => 1823 index.to_f => 1823.97333333333
