This (mostly) follows the Microsoft Manual of Style for Technical Publications. Lame I know, but it's a reference:
Examples:
class String def titlecase non_capitalized = %w{of etc and by the for on is at to but nor or a via} gsub(/\b[a-z]+/){ |w| non_capitalized.include?(w) ? w : w.capitalize }.sub(/^[a-z]/){|l| l.upcase }.sub(/\b[a-z][^\s]*?$/){|l| l.capitalize } end end
Examples:
"this is a story in the new york times".titleize # => "This is a Story In the New York Times" "what in the world was that for?".titleize # => "What In the World Was That For?" "searching for a CHEAP overhead projector?".titleize # => "Searching for a CHEAP Overhead Projector?"
