如何定义对特定字符串使用`replace-string`的Emacs命令 [英] How to define an Emacs command that uses `replace-string` for a specific string

问题描述

在 Emacs 中，我正在处理一个文本文档，将 unicode 纯文本转换为 LaTeX.

In Emacs, I am processing a text document, converting from unicode plaintext to LaTeX.

我想运行几组正则表达式，例如

There are a few sets of regular expressions that I want to run, for example

M-x replace-string ± RET pm RET
M-x replace-string µ RET  	extmu 

如何保存这些正则表达式以便我可以重复运行它们?

How do I save these regular expressions so that I can run them repeatedly?

谢谢

推荐答案

我通常喜欢编写自定义命令，这是您第一次替换的命令:

I generally like writing custom commands, here's the one for your first replacement:

(defun replace-plus-minus ()
  (interactive)
  (replace-string "±" "\pm" nil (point-min) (point-max)))

但是，您也可以使用键盘宏.查看 wiki 和 文档.

But, you can also use keyboard macros. Check out the wiki and docs.

基本上，你会这样做:

C-x ( M-x replace-string ± RET pm RET C-x )

然后你可以给它命名，并将它保存到你的 .emacs 中:

Then you can name it, and save it to your .emacs:

M-x name-last-kbd-macro
M-x insert-kbd-macro
