Emacs Lisp;如何从任何类型的变量中得到一个字符串？ [英] Emacs lisp; how to make a string from a variable of any type?

问题描述

显示类似于错误调用函数的错误消息，例如：

Like error messages for wrongly called functions show, eg.:

(message (file-attributes "."))

产生消息：

"eval: Wrong type argument: stringp, ("/home14/tjones" 1 0 0 (20415 35598) (20211 19255) (20211 19255) 14 "lrwxrwxrwx" t ...)"

您如何故意进行这种类型的翻译，例如：

How do you do this type of translation intentionally, eg.:

(message (thing-to-string (file-attributes ".")))

要发送类似消息：

("/home14/tjones" 1 0 0 (20415 35598) (20211 19255) (20211 19255) 14 "lrwxrwxrwx" t ...)

这仅用于调试/信息。我假设消息正在执行某种方式，但这对我们的用户开放吗？

This is for debugging/info only. I'm assuming there's a way as message is doing it, but is this exposed to us users?

推荐答案

查看 prin1到字符串和相关功能（ prin1 ， princ ，等等）。并尝试使用手册！ http://www.gnu.org/software/emacs /manual/html_node/elisp/Output-Functions.html

Look into prin1-to-string and related functions (prin1, princ, etc). And do try the manual! http://www.gnu.org/software/emacs/manual/html_node/elisp/Output-Functions.html
