如何将当前提交(由 elisp 的一小部分返回)插入到 ?? 中？ 我应该找到了一种方法，但它在正常导出时无效，可能只在缠结期间有效。

Answer 1

如果您为代码块添加名称，那么您可以从其他地方调用该 block 代码:

#+NAME: commit
#+BEGIN_SRC emacs-lisp :exports none :tangle no
  (substring (shell-command-to-string "git rev-parse --short HEAD") 0 -1)
#+END_SRC

This corresponds to git commit call_commit().

导出时得到的输出:

This corresponds to git commit `2464d0a'.

这已记录在案 in the org-mode manual用于源代码块评估。
