emacs - elisp:有没有办法获取当前 .el 模块的名称(如 C 中的 __FILE__)？

Question

在我的 elisp 模块的顶部，我想做一些简单的事情:

(message (concat "Loading " (expand-file-name (current-elisp-module) ".")))

Answer 1

您可以使用变量 load-file-name , 由函数 load 设置，记录如下:

Full name of file being loaded by `load'.

如手册中所述:

When Emacs is in the process of loading a file, this variable’s value is the name of that file, as Emacs found it during the search described earlier in this section.

注意: buffer-file-name例行公事并不像您预期​​的那样有效。
