设置byte-compile-dest-file-function [英] Setting byte-compile-dest-file-function

问题描述

我想使用相对路径（如 ../ foo ）设置emacs lisp字节编译的目标目录。我想我应该使用 byte-compile-dest-file-function ，但不知道如何设置它。如何设置？

I want to set the destination directory for emacs lisp byte compilation using relative path such as ../foo. I figured out I should use byte-compile-dest-file-function, but do not know how to set it. How can I set it?

推荐答案

设置 byte-compile-dest-function 变量，您可以在init文件中交互使用 customize-variable 或 setq 。由于你必须以任何方式写一个函数做这个工作，所以我会建议后者，这样一来你的init文件就在同一个位置。

To set the byte-compile-dest-function variable, you can use either customize-variable interactively, or setq in your init file. Since you'll have to write a function doing the job either way, I would recommand the latter, so that everything is in the same place in your init file.

例如：

(defun my-dest-function (filename)
  (concat (file-name-directory filename)
          "../"
          (file-name-sans-extension (file-name-nondirectory filename))
          ".elc"))
(setq byte-compile-dest-file-function 'my-dest-function)
