(fork) I'm trying to split a phrase into 6 or less rows of 12 or less letters each.

phrase_splitter.rb

LEN = 60
LIMIT = 12

phrase = nil

begin
  puts "Enter phrase. #{LEN} characters or less."
  phrase = gets.chomp
end while phrase.length > LEN

lines = []

phrase.downcase.scan /[a-z]+/ do |word|
  if lines.empty? || lines.last.length + 1 + word.length > LIMIT
    lines << word.dup
  else
    lines.last << " " << word
  end
end

puts lines
