Rearrange song lyrics so it's easier to put guitar chords over them

transpose_lyrics.rb

#!/usr/bin/env ruby
# Rearrange song lyrics so it's easier to put guitar chords over them: put the
# first lines of each verse, which share the same chords, into the first
# paragraph. Second lines go into the second paragraph, etc.
#
# Meant to be used with Unix piping: `cat somefile.txt | ./this_script > output.txt

lyrics           = STDIN.read
paragraphs       = lyrics.split("\n\n")
lines            = paragraphs.map { |paragraph| paragraph.split("\n") }
transposed_lines = lines.transpose # Yay for Ruby!
new_paragraphs   = transposed_lines.map { |paragraph| paragraph.join("\n") }
new_lyrics       = new_paragraphs.join("\n\n")
puts new_lyrics

Thank you! I will incorporate this into my guitar program some how!!
