Code i wrote to that the dramatized audio bible (word of promise) i bought and downloaded as MP3 and rename the title to something that can be displayed as a whole on the Iphone , and also generate a CSV file of chapters and minutes for my curiousity.

booksofbible.rb

require "rubygems"
require "mp3info"
require "csv"

chapterarray = []
#Dir.glob("/Users/klumsy/Downloads/bible/01_Genesis/*.mp3") do |f|
Dir.glob("/Users/klumsy/Downloads/bible/**/*.mp3") do |f|
  Mp3Info.open(f) do |mp3info|
    title = mp3info.tag.title
    puts title

    newtitle = title.sub("Chapter ","")
    newtitle = newtitle.sub("(WOP-","")
    newtitle = newtitle.sub(")","")
    
    length = mp3info.length
    bookofbible = title.scan(/[0-9]{2}(?=\))/)[0].to_i
    puts bookofbible
    #Dunno why this regex returns an array of arrays rather than just an 
    #array but oh well
    book = newtitle.scan(/\s([a-zA-Z0-9_\s]+)(?=\s[0-9]{1,})/)[0][0].lstrip
    chapter = newtitle.scan(/\s[0-9]{2,}/)[0].lstrip.to_i

    # i know adding to an array like this is slow as it creates a new array
    # but for a one once utility i don't care
    chapterarray += [ [bookofbible,book,chapter,length ] ]
    
   #show some info on screen
    
    puts ":" + newtitle
    
    #mp3info library actually updates the MP3s when you set properties
   mp3info.tag.title = "B" + newtitle
     album = "WOP" + String(bookofbible) + " "+ book
     puts "!" + album
    mp3info.tag.album = album
    
  end
end
#create a CSV file
CSV.open("/Users/klumsy/Downloads/booksofbible.csv", "wb") do |csv|
    #write a header row
    csv << ["BookNum","Book","Chapter","Seconds"]
    #Go through our array of arrays, and for each row write it to the CSV file
    chapterarray.each { |item| csv << item }
 
  end

i would have written it in powershell, but was on my mac at the time, plus mp3info library did the trick nicely
