将文本体分成句子但保留标点符号？

Question

我试图在2个html载文文本之间产生一个人类可读的类wiki差异.我正在使用diff-lcs,第一步是将字符串(字符数组)分成一个句子数组,但保留它们的标点符号.

"I am a lion. Hear me roar! Where is my cub? Never mind, found him.".magic_split(/[.?!]/)
# => "I am a lion." "Hear me roar!" "Where is my cub?" "Never mind, found him."

这应该可以解决问题

"I am a lion. Hear me roar! Where is my cub? Never mind, found him.".gsub(/[.?!]/, '\1|').split('|')

除了gsub似乎无法插入字符.?!.而是它返回这个

"I am a lion| Hear me roar| Where is my cub| Never mind, found him|"

什么是进行非破坏性拆分的最简单方法？因为它保持它分裂的字符.

Answer 1

scan应该做的伎俩(扔strip在那里摆脱尾随空格).

s = "I am a lion. Hear me roar! Where is my cub? Never mind, found him."
s.scan(/[^\.!?]+[\.!?]/).map(&:strip) # => ["I am a lion.", "Hear me roar!", "Where is my cub?", "Never mind, found him."]

Answer 2

我认为应该是\0

>> string = "I am a lion. Hear me roar! Where is my cub? Never mind, found him."
>> string.gsub(/[.?!]/, '\0|') 
   # "I am a lion.| Hear me roar!| Where is my cub?| Never mind, found him.|"
