Subject: Re: How to "find" new lines

don't know if this will help you but ruby 1.9 has the each_line method.

example:

def line_count( s)
  c = 0
  s.each_line { |l| c+=1 }
  return( c)
end

>>line_count( "I am \na multi\nline\nstring!")
 => 4

if you want to test against the ascii equivalent in 1.8.7 it's ?\n and
in 1.9.2 it's "\n".ord which should return 10 in decimal format.
