rbJL.net · 27 · New Array and Enumerable methods in Ruby 1.9.2: keep_if, chunk...

Hi, I am Jan. This is my old Ruby blog. I still post about Ruby, but I now do it on idiosyncratic-ruby.com. You should also install Irbtools to improve your IRB. In Ruby, dealing with Arrays and similar objects is pretty fun. And we have gotten more possibilities with Ruby 1.9.2 :) The NEWS file says: * Array * new method: * Array#keep_if * Array#repeated_combination * Array#repeated_permutation *

現在のarrayとかから対象の要素だけを残す select! とか便利そう。
