非交互式Emacs正则表达式替代 [英] Non-interactive emacs regex substitute

问题描述

emacs lisp中是否有一个（非交互式）函数来替换任意字符串中匹配的正则表达式？

Is there a (non-interactive) function in emacs lisp that replaces a matched regex in an arbitrary string?

ie

(sub regex search-string replace-string)

如

(sub "[^.x/]" "beef./xxfoo" "")
;; => "./xx"

推荐答案

是，请参见函数替换字符串中的正则表达式。如此简单。

Yes, see function replace-regexp-in-string. Simple as that.

要替换缓冲区中的匹配文本，您可以使用 replace-regexp 。

And to replace matching text in a buffer, you have replace-regexp.

替换不必是文字字符串，但是可以涉及检索部分regexp匹配和其他操作。使用 C-h f 查看这些功能的文档。

The replacement does not need to be a literal string, but can involve retrieving parts of the regexp match and other manipulations. Use C-h f to see the doc for these functions.
