使用 Ruby 将字符串拆分为单词和标点符号 [英] Splitting a string into words and punctuation with Ruby

问题描述

我在 Ruby 中工作，我想将一个字符串及其标点符号拆分为一个数组，但我想将撇号和连字符视为单词的一部分.例如，

I'm working in Ruby and I want to split a string and its punctuation into an array, but I want to consider apostrophes and hyphens as parts of words. For example,

s = "here...is a     happy-go-lucky string that I'm writing"

应该变成

["here", "...", "is", "a", "happy-go-lucky", "string", "that", "I'm", "writing"].

我得到的最接近的仍然不够，因为它没有正确地将连字符和撇号视为单词的一部分.

The closest I've gotten is still inadequate because it doesn't properly consider hyphens and apostrophes as part of the word.

这是我迄今为止最接近的:

This is the closest I've gotten so far:

s.scan(/\w+|\W+/).select {|x| x.match(/\S/)}

产生

["here", "...", "is", "a", "happy", "-", "go", "-", "lucky", "string", "that", "I", "'", "m", "writing"]

.

推荐答案

您可以尝试以下操作:

s.scan(/[\w'-]+|[[:punct:]]+/)
#=> ["here", "...", "is", "a", "happy-go-lucky", "string", "that", "I'm", "writing"]
