Oh, yes, there's always ri. I tend to forget about it because I rely  
on my pickaxe PDF.

~ mg: ri String#chomp
----------------------------------------------------------- String#chomp
      str.chomp(separator=$/)   => new_str
------------------------------------------------------------------------
      Returns a new +String+ with the given record separator removed  
from
      the end of _str_ (if present). If +$/+ has not been changed from
      the default Ruby record separator, then +chomp+ also removes
      carriage return characters (that is it will remove +\n+, +\r+, and
      +\r\n+).

         "hello".chomp            #=> "hello"
         "hello\n".chomp          #=> "hello"
         "hello\r\n".chomp        #=> "hello"
         "hello\n\r".chomp        #=> "hello\n"
         "hello\r".chomp          #=> "hello"
         "hello \n there".chomp   #=> "hello \n there"
         "hello".chomp("llo")     #=> "he"

~ mg: ri String#strip
----------------------------------------------------------- String#strip
      str.strip   => new_str
------------------------------------------------------------------------
      Returns a copy of _str_ with leading and trailing whitespace
      removed.

         "    hello    ".strip   #=> "hello"
         "\tgoodbye\r\n".strip   #=> "goodbye"
