Visual Studio Code 中的多行正则表达式 [英] Multi-line regular expressions in Visual Studio Code

问题描述

我想不出一种方法让正则表达式匹配停止不是在行尾，而是在 VS Code 的文件尾?是工具限制还是存在某种我不知道的模式?

I cannot figure a way to make regular expression match stop not on end of line, but on end of file in VS Code? Is it a tool limitation or there is some kind of pattern that I am not aware of?

推荐答案

似乎 CR 与 [\s\S] 不匹配.将 \r 添加到这个字符类:

It seems the CR is not matched with [\s\S]. Add \r to this character class:

[\s\S\r]+

将匹配任何 1+ 个字符.

will match any 1+ chars.

其他证明有效的替代方法是 [^\r]+ 和 [\w\W]+.

Other alternatives that proved working are [^\r]+ and [\w\W]+.

如果要让任何字符类匹配换行符，无论是正字符类还是负字符类，都需要在其中添加\r.

If you want to make any character class match line breaks, be it a positive or negative character class, you need to add \r in it.

示例:

• 两个最接近的 a 和 b 字符之间的任何文本:a[^ab\r]*b
• START 和最近的 STOP 字之间的任何文本:
  • START[\s\S\r]*?STOP
  • START[^\r]*?STOP
  • START[\w\W]*?STOP
  • Any text between the two closest a and b chars: a[^ab\r]*b
  • Any text between START and the closest STOP words:
    • START[\s\S\r]*?STOP
    • START[^\r]*?STOP
    • START[\w\W]*?STOP
    • START(?:(?!START)[\s\S\r])*?STOP
