Emacs Lisp 宏步进器
SLIME 宏步进器有 Elisp 类似物吗？具体来说，我正在寻找将代码扩展到新缓冲区中的下一个扩展步骤（或只是最终扩展）的东西。
天真的
(defun macroexpand-point ()
(interactive)
(let ((b (get-buffer-create "*el-macroexpansion*"))
(expansion (format "%s" (macroexpand (thing-at-point 'sexp)))))
(with-current-buffer b
(insert expansion)
(display-buffer b))))
不会做我在这里期待的事情。
Is there an Elisp analogue for the SLIME macrostepper? Specifically, I'm looking for something that expands code at point into the next expansion step (or just the final expansion) in a new buffer.
The naive
(defun macroexpand-point ()
(interactive)
(let ((b (get-buffer-create "*el-macroexpansion*"))
(expansion (format "%s" (macroexpand (thing-at-point 'sexp)))))
(with-current-buffer b
(insert expansion)
(display-buffer b))))
doesn't do what I'm expecting here.

人们可能会发现 macrostep 包很有用。
关于 Macrostep 的快速指南：
安装软件包后，无需进一步自定义，您可以执行以下操作：
将光标移至要扩展的表达式之前，然后执行
Mx Macrostep-expand eeee e来扩展它的步骤一步一步。简短的帮助消息显示在回显区域中，说明如何退出和如何取消展开。可以在 dash.el 中的

Quick howto on macrostep:
After you install the package, and without further customization, you can do this:
Move cursor before the expression you want to expand, then do
M-x macrostep-expand e e e e eto expand it step by step. Short help message gets displayed in the echo area on how to quit and how to unexpand.One can test this out on the
