如何将\\\网更改为vim中的常用字符？ [英] How to change \u7f51 to common character in vim?

问题描述

在红宝石中，因为它在系统范围内是utf-8编码的。所以很简单：

string =\\\网\\\址\\\不\\\能\\\为\\\空

=>网址不能为空

任何人都可以告诉我如何在vim中执行此操作？

解决方案

如果您想插入Unicode字符，请参阅 utf-8-typing 帮助。 p>

例如， Ctrl-V u7f51 将插入网。

如果您想在Vim脚本中使用，可以使用与Ruby相同的Unicode转义;命令 echo\\\网\\\址\\\不\\\能\\\为\\\空将回显您在问题中提供的字符串。

意识到这一点， Ctrl-R 发挥作用，和 = 注册;请参阅 i_CTRL-R 和 i_CTRL-R _ = 更多信息。

鉴于以下内容，光标位于双引号字符串中：

  string =\\\网\\\址\\\不\\\能\\\为\\\空
  

应用这些击键： c 我 Ctrl-R = 控制-R 输入 Esc

这将会变成如下：

  string =网址不能为空
  

尝试弄清楚它是如何工作的，但我如果你不明白，会更多地解释。

In ruby, since it's utf-8 encoded in the system wide. so it's pretty straight forward:

string = "\u7f51\u5740\u4e0d\u80fd\u4e3a\u7a7a"

=>网址不能为空

Anyone can I tell me that how to do this in vim?

解决方案

If you are wanting to insert Unicode characters, see the utf-8-typing help.

For example, Ctrl-V u7f51 will insert 网.

If you are wanting it in Vim scripts, you can use Unicode escapes in the same way as in Ruby; the command echo "\u7f51\u5740\u4e0d\u80fd\u4e3a\u7a7a" will echo the string you provide in your question.

Being aware of this, Ctrl-R comes into play, with the " and = registers; see the docs for i_CTRL-R and i_CTRL-R_= for more info.

Given the following, with the cursor inside the double-quoted string:

string = "\u7f51\u5740\u4e0d\u80fd\u4e3a\u7a7a"

Apply these keystrokes: ci"Ctrl-R="Ctrl-R""EnterEsc

This will turn it into the following:

string = "网址不能为空"

Try to figure out how it works yourself, but I'll explain more if you can't figure it out.
