Emacs:接收进程输出的常规方式是什么

Question

我的目标是从Emacs中的进程中获得输出。

例如，M-x run-python给了我一个python外壳*Python*，我可以将python代码发送到它。如果我将print "hello world"发送到*Python*，我希望Emacs在执行完成后可以知道结果，并在迷你缓冲区中回显它。

是否可以添加回调之类的内容？

感谢@lawlist的评论，我通过创建以下过滤函数并将其分配给具有(set-process-filter (get-buffer-process "*MozRepl*") 'moz-controller-repl-filter) 的进程（在我的情况下为*MozRepl*）来解决问题

(defun moz-controller-repl-filter (proc string)
  "Filter function of *MozRepl*.
It gets the useful output of *MozRepl*, store it in `moz-controller-repl-output` and `kill-ring`"
  (when (buffer-live-p (process-buffer proc))
    (unless (string= string "repl> ")   ; ignore empty output (page up, page down, etc)
      (setq moz-controller-repl-output
            (replace-regexp-in-string ""\(.+\)"nrepl> " "\1" string))
      (kill-new moz-controller-repl-output) ; append to kill-ring
      (message moz-controller-repl-output) ; show the copied content in echo area
      )
    (with-current-buffer (process-buffer proc)
      (let ((moving (= (point) (process-mark proc))))
        (save-excursion
          ;; Insert the text, advancing the process marker.
          (goto-char (process-mark proc))
          (insert string)
          (set-marker (process-mark proc) (point)))
        (if moving (goto-char (process-mark proc)))))))
