从数组中清除空字符串 [英] Clearing Empty Strings from an Array

问题描述

我正在处理一堆由字符串组成的数组，而我多次写过.delete_if { |str| str.empty? }

I'm dealing with a bunch of arrays made of strings and many a times I've written .delete_if { |str| str.empty? }

现在，我知道我可以自己将此方法添加到数组类中，但是我希望有一种内置的方法可以执行此操作，而无需在基类中添加非标准方法.除了向基类添加方法之外，它还很有趣，但出于可维护性的原因，我不想这么做.

Now, I know I can add this method to the array class myself but I'm hoping there's a built in way to do this without having non-standard methods added to base classes. As much fun as adding methods to base classes is, it's not something I wanna do for maintainability reasons.

有内置的方法可以处理吗?

Is there a built in method to handle this?

推荐答案

有一个简短格式

array.delete_if(&:empty?)
