regex - Notepad++:删除字符串中多个字符之后的所有内容

Question

下面是Notepad++中每行24个字符的示例。我需要将每行字符限制为 14 个字符。

Hell, how is she today ?

我需要它看起来像下面这样:

Hell, how is

我使用了这段代码

Find what: ^(.{1,14}).*
Replace with: $1

但是，它显示“Hell, how is s”，拼写错误。

如何在 Notepad++ 中将字符数限制为每行 14 个字符并删除最后一个单词？

Answer 1

这应该适合你:

查找内容:^(.{1,14}(?<=\S)\b).*$

替换为:$1

所以对于Hell, how is she today ?输出是:Hell, how is

DEMO

^                # The beginning of the string
(                # Group and capture to \1:
  .{1,14}        # Any character except \n (between 1 and 14 times (matching the most amount possible))
  (?<=\S)        # This lookbehind makes sure the last char is not a space
  \b             # The boundary between a word char (\w). It matches the end of a word in this case
)                # End of \1
.*$              # Match any char till the end of the line
