Notepad++ 中字符行的条件合并

Question

我在 notepad++ 中有一个这样的问题；

123. The airplane will not land in time
if weather is not clear due to rain and storm. Are you acceptable to re
turn the flight? (the question is splitted into 2 or 3 lines)
a yes
b no
c. yes but refund money
d. we will risk and land

我希望将上述问题放在一行中。所有问题都将以答案选项“a”开头。由于问题超过 100 个，因此很难在每个问题上都应用 CTRL+J。

需要您的建议。

Answer 1

您可以使用以下表达方式：

• 找什么：\r\n(?!(\d{3}|[a-z])\.? )
  （取决于您的操作系统，您可能需要删除\r）
• 替换为：“”（没有什么）
• 确保选中“正则表达式”

无论字母后面是否有点（“c.”），此方法都有效（“a”）。

Answer 2

• Ctrl+H
• 找什么：(?:^\d+\.|\G).+\K\R(?!^[a-z]\.?\h)
• 用。。。来代替：A SPACE
• 取消勾选匹配大小写
• 检查环绕
• 检查正则表达式
• 取消选中. matches newline
• Replace all

解释：

(?:             # start non capture group
  ^             # beginning of line
    \d+         # 1 or more digits
    \.          # a dot
  |             # OR
    \G          # restart from last match position
)               # end group
.+              # 1 or more any character but newline
\K              # forget all we have seen until this position
\R              # any kind of linebreak (i.e. \r, \n, \r\n)
(?!             # neagative lookahead, zero-length assertion that makes sure we haven't after: 
  ^             # beginning of line
    [a-z]       # a small letter
    \.?         # an optional dot
    \h          # 1 horizontal space
)
