Ruby：多维％w数组？

Question

Could a multidimensional array be defined with a single %w directive? 可以使用单个%w指令定义多维数组吗？

For example: 例如：

the_array = %w(one two three{some separator}four five{some separator}six seven eight nine)

I need this to build an array with variable amount of items in a row: 我需要这个来构建一个包含可变数量的项目的数组：

the_array = [
    ['one', 'two', 'three'],
    ['four', 'five'],
    ['six', 'seven', 'eight', 'nine']
]

Answer 1

You can do the inverse, use the short-hand word array notation in a standard array brackets. 您可以执行反向操作，在标准数组括号中使用简写字数组表示法。

the_array = [%w(one two three), %w(four five), %w(six seven eight nine)]

The goal of the short-hand word notation is to save all the punctuation in terms of commas and quotation marks. 简写单词表示法的目的是用逗号和引号来保存所有标点符号。
