regex - How to find and replace upper and lowercase and keep capitalization in Vim

Question

Let's say I have:

foo and Foo

How can I find and replace it to

bar and Bar

With one regex/find and replace command in Vim? By default I have my Vim setup to find either uppercase and lowercase when searching. Now I just want to replace keeping the capitalization. Is this even possible?

Answer 1

我推荐 Tim Pope 的Abolish插件。它提供了:Subvertor:S命令，可以完全按照您的要求进行操作。

:%S/foo/bar/g

Vimcast的Drew Neil有一个不错的截屏视频，Supercharged 替换为 :Subvert。

Answer 2

我建议您set ignorecase!在搜索之前和之后进行。如果您经常进行区分大小写的搜索，那么您可以将其映射到某些东西。如果您经常使用混合大小写和大小写匹配，您可能需要查看插件。
