MusicCache You have a lot of music files (mp3 support only for now). You want to know what you have, where you have it, and what shape it's in (duplicates, encodings, size, track completion, mislabelings). You'd also like to be able to query this data, for use in other programs – say a web based music player like FTANG (http://github.com/maxogden/ftang). You could use MusicCache to do these things! Music cache is written in ruby, and stores in Redis (<= 2.0). it is executed by: music-cache origin destination enact e.g. music-cache /home/YourUser/unsorted /home/YourUser/Music enact By removing the 'enact' word, the program does a dry run. IMPORTANT DEPENDENCY INFO (I will not be a dependency coward. Join me.): We're using bundler here. You should to! FOR MY 1.8 USERS: bundle install FOR MY 1.9 USERS, currently broken: mp3info is broken in 1.9.2 I'm working on this problem. if you want to help ... bundle install This program uses ruby-mp3info which can be found at: http://ruby-mp3info.rubyforge.org/ And uses the ruby implementation of Levenshtein distance, which can be found at: http://rubyforge.org/frs/?group_id=6257 This program was originally inspired by TheDevelopment's ruby-id3-sort, and still resembles it in a few places. please see http://github.com/TheDevelopment/ruby-id3-sort
