如何“URL解码” Emacs Lisp中的一个字符串？ [英] How to "URL decode" a string in Emacs Lisp?

问题描述

我有一个字符串，如foo％20bar，我想要foo bar。

我知道在Emacs Lisp中解码URL编码的字符串（查询字符串）必须是一个内置函数，但是对于我来说，有没有人会记得这个叫什么？

解决方案

org-link-unescape 为非常简单的案例做这个工作... w3m-url-decode -string 更好，但它并没有内置，我本地的版本不能与Emacs 23工作。

I've got a string like "foo%20bar" and I want "foo bar" out of it.

I know there's got to be a built-in function to decode a URL-encoded string (query string) in Emacs Lisp, but for the life of me I can't find it today, either in my lisp/ folder or with google.

Anybody remember what it's called?

解决方案

org-link-unescape does the job for very simple cases ... w3m-url-decode-string is better, but it isn't built in and the version I have locally isn't working with Emacs 23.
