Vim 正则表达式捕获组 [bau ->byau : ceu ->cyeu] [英] Vim Regex Capture Groups [bau -> byau : ceu -> cyeu]

问题描述

我有一个单词列表:

bau
ceu
diu
fou
gau

我想把那个列表变成:

byau
cyeu
dyiu
fyou
gyau

我尝试命令失败:

:%s/(w)(ww)/1y2/g

鉴于这不起作用，我需要更改什么才能使正则表达式捕获组在 Vim 中工作?

Given that this doesn't work, what do I have to change to make the regex capture groups work in Vim?

推荐答案

解决这个问题的一种方法是确保模式用转义括号括起来:

One way to fix this is by ensuring the pattern is enclosed by escaped parentheses:

:%s/(w)(ww)/1y2/g

使用 v 稍微短一些(和更多 magic-al)，这意味着在它之后的模式中除了 '0'- 之外的所有 ASCII 字符'9', 'a'-'z', 'A'-'Z' 和 '_' 有一个特殊含义:

Slightly shorter (and more magic-al) is to use v, meaning that in the pattern after it all ASCII characters except '0'-'9', 'a'-'z', 'A'-'Z' and '_' have a special meaning:

:%s/v(w)(ww)/1y2/g

见:

• :help (
• :help v
