如何指定“光标下的字”在VIM的命令行？ [英] How do I specify "the word under the cursor" on VIM's commandline?

问题描述

我想在VIM中写一个指定光标下的字的命令。例如，让我们把光标放在一个单词上，让它出现两次。例如，如果单词是abc，我想要abcabc，那么我可以键入：

I want to write a command that specifies "the word under the cursor" in VIM. For instance, let's say I have the cursor on a word and I make it appear twice. For instance, if the word is "abc" and I want "abcabc" then I could type:

:s/\(abc\)/\1\1/

但我想能够将光标移动到def并使用相同的命令将其更改为defdef：

But then I'd like to be able to move the cursor to "def" and use the same command to change it to "defdef":

:s/\(def\)/\1\1/

:s/\(*whatever is under the commandline*\)/\1\1

推荐答案

< cword> 是光标下面的字词（：help < cword> ）。

<cword> is the word under the cursor (:help <cword>).

对不起，我应该在这个答案更完整。

Sorry, I should have been more complete in this answer.

你可以nmap一个命令，或者这个系列的懒惰的键盘工作：

You can nmap a command to it, or this series of keystrokes for the lazy will work:

b #go to beginning of current word
yw #yank to register

然后，当您输入模式时，您可以按< control-r> 0< enter& code>它会在你的命令中粘贴第0个寄存器的内容。

Then, when you are typing in your pattern you can hit <control-r>0<enter> which will paste in your command the contents of the 0-th register.

你也可以像这样命令：

:nmap <leader>w :s/\(<c-r>=expand("<cword>")<cr>\)/

这将映射命中'\'和'w'用

Which will map hitting '\' and 'w' at the same time to replace your command line with

:s/\(<currentword>\)/
