ruby - A nil class when trying to initialize a deck of cards -


the following code resulting in nil , can't figure out why. there wrong initialization?

class card     values = %w(2 3 4 5 6 7 8 9 10 j q k a)     suits = %w(s h d c)      def initialize(suit, value)         @suit = suit         @value = value     end end  class deck     attr_accessor :cards      def initialize         @cards = []         card::suits.each |suit|             card::values.each |value|                 @cards << card.new(suit, value)             end         end     end end  deck.new  p @cards

you create new object deck.new, don't print value of cards - print @cards instance variable in context nil.

you wanted p deck.new.cards.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
