Get items of an array that match a condition

[DtY]

I feel stupid asking this.. I should know the answer, but I just can't remember what method I want. I looked at [].methods, but couldn't find anything that looked right.
What I want is the method that will give me this:

Ruby:

> [1,2,3,4,5,6,7,8,9,10].someMethod{|n| n%2 == 0} [2,4,6,8,10]

Thanks

Found it, it's Array#select

Ruby:

class FixNum     def even?         self % 2 == 0     end end module Enumerable     def all_evens         select { |x| x.even? }     end end

Building on wtd's example, if you're using Rails or Ruby 1.9:

Ruby:

class FixNum     def even?         self % 2 == 0     end end array.select(&:even?)
