I'm trying to convert the strings below into an array of all the unique
words converted to lower case.

This is a ruby code.
More lovely code.
Better than PHP.
That is it.

Thanks

Ok:

comment =<<COMMENT
This is a ruby code.
More lovely code.
Better than PHP.
That is it.
COMMENT

comment.gsub(/[-.,!:;'"]/, '').split(/\s+/).map{|w|
w.downcase}.uniq.sort

=> ["a", "better", "code", "is", "it", "lovely", "more", "php",
"ruby", "than", "that", "this"]

Try this:

require 'set'

comment = <<COMMENT
This is ruby code.
More lovely code.
Better than PHP.
That is it.
COMMENT

lower = comment.downcase
lines = lower.split(".\n")

unique_words = Set.new()
lines.each do |line|
words = line.split()
words.each do |word|
unique_words << word
end
end

p unique_words
