You can use regular expressions for case insensitivity or downcase the
string - regular expressions have the benefit of being far more
flexible...

# note with the regexp, unless we test for its absence we can forgo the chomp
happy = case gets
  when /not.*good/i : false
  when /good/i : true
  when /ok/i : true
  when /fine/i : true
  when /wonderful/i : true
  else false  # am I the only one that feels that the : should be
allowed here for symmetry
end
puts happy ? "Good buddy" : "oh i am sorry"

Hope that helps
