ruby – 带有空格的Word数组

发布时间：2020-12-17 04:33:34 所属栏目：百科来源：网络整理

导读：我开始喜欢单词数组,但今天我面临挑战： a = %w[ faq contact 'about us' legal 'bug reports' ] = ["faq","contact","'about","us'","legal","'bug","reports'"] a = %w[ faq contact "about us" legal 'bug reports' ] = ["faq",""about","us"","reports

我开始喜欢单词数组,但今天我面临挑战：

> a = %w[ faq contact 'about us' legal 'bug reports' ]
 => ["faq","contact","'about","us'","legal","'bug","reports'"] 
 > a = %w[ faq contact "about us" legal 'bug reports' ]
 => ["faq",""about","us"","reports'"]

我怎么能有空格元素？

解决方法

您可以转义空格字符

a = %w[ faq contact about us legal bug reports ]
a # => ["faq","about us","bug reports"]

但我仍然考虑使用“完整”数组文字.在这种情况下,它们不那么令人困惑.
