Question

我有一个多行字符串，例如：

"The wolverine is now es-
sentially absent from 
the southern end
of its European range."

我想要的是：删除连字符并连接前一行中的单词。结果，应该是：

"The wolverine is now essentially
absent from  
the southern end
of its European range."

Answer 1

尝试类似

的内容

new_string = string.gsub("-\n", "")

这将删除所有短划线，后跟\n，表示新行

Answer 2

似乎不是最优化的解决方案，但它在大多数情况下都有效：

text = "The wolverine is now es-\nsentially absent from \nthe southern end\nof its European range."

splitted_text = text.split("-\n")

splitted_text.each_with_index do |line, index|
  next_line = splitted_text[index + 1]

  if next_line.present?
    line << next_line[/\w+/] + "\n"
    next_line.sub!(/\w+/, '').strip!
  end
end

splitted_text.join

结果

"The wolverine is now essentially\nabsent from \nthe southern end\nof its European range."

Answer 3

在连接的单词

之后连接包裹的单词和断行的部分

text = "The wolverine is now es-\nsentially absent from \nthe southern end\nof its European range."
=> "The wolverine is now es-\nsentially absent from \nthe southern end\nof its European range."

text.gsub(/-\n([^\s]*)\s/,$1+"\n")
=> "The wolverine is now essentially\nabsent from \nthe southern end\nof its European range."

Answer 4

这就是你需要的：

string.gsub(/(-\n)(\S+)\s/) { "#{$2} \n" }

此代码将删除-\n以加入“基本上”一词，并在其后添加\n，返回您的愿望结果：

“狼獾现在已经从它的欧洲范围的南端开始了。\ n”

如何连接单词，在Ruby中使用换行符？
