Vim 中的多行正则表达式支持 [英] Multi-line regex support in Vim
问题描述
我注意到用于跨多行匹配的标准正则表达式语法是使用/s,如下所示:
I notice the standard regex syntax for matching across multiple lines is to use /s, like so:
This is\nsome text
/This.*text/s
例如,这在 Perl 中有效,但在 Vim 中似乎不受支持.相反,我必须更加具体:
This works in Perl for instance but doesn't seem to be supported in Vim. Instead, I have to be much more specific:
/This[^\r\n]*[\r\n]*text/
我找不到任何理由说明为什么会这样,所以我想我可能只是错过了 vim 帮助中的相关部分.
I can't find any reason for why this should be, so I'm thinking I probably just missed the relevant bits in the vim help.
有人能以一种或另一种方式确认这种行为吗?
Can anyone confirm this behaviour one way or the other?
推荐答案
是的,Perl 的 //s
修饰符在 Vim 正则表达式上不可用.有关详细信息以及 Vim 和 Perl 正则表达式之间其他差异的列表,请参阅 :h perl-patterns
.
Yes, Perl's //s
modifier isn't available on Vim regexes. See :h perl-patterns
for details and a list of other differences between Vim and Perl regexes.
相反,您可以使用 \_.
,这意味着匹配任何单个字符,包括换行符".它比你拥有的要短一点.见:h/\_.
.
Instead you can use \_.
, which means "match any single character including newline". It's a bit shorter than what you have. See :h /\_.
.
/This\_.*text/
