Материал из Wiki.crossplatform.ru
Get rid of that extra l in alll:
puts "That"s alll folks".delete "l"
negate all or part of an argument with the caret (^), similar to its use in regular expressions
puts "That"s all folks".delete "abcdefghijklmnopqrstuvwxyz", "^ha"
use two ls instead of one for delete method
puts "That"s alll folks".delete "ll"
When there is more than one argument, take the intersection.
# Arguments that begin with ^ are negated. "hello".count("a-z", "^aeiou") # => 3: count lowercase consonants "hello".delete("a-z", "^aeiou") # => "eo: delete lowercase consonants
With delete or delete!, you can delete characters from a string
puts "That"s call folks!".delete "c"
