I have grown fond of glark 
http://glark.sourceforge.net/
a ruby enhanced grep (probably first read about on this list), so i do:

glark -F "blue bold on black" -T "red on black" -B 0 -A 0 \
  "^\s*(module|class|def|attr_|require|include)" file.rb

rather as that string is faily long, i have the following
function in my shell (zsh):

,glrb() { glark -F "blue bold on black" -T "red on black" -B 0 -A 0 \
  "^\s*(module|class|def|attr_|require|include)" $1 } # ,glrb file.rb
