杀死nodejs-repl劣质进程并重新启动它

Question

下面的函数将app.js缓冲区内容发送到 * nodejs * repl缓冲区，该缓冲区有效。唯一的问题是当它第二次执行时它不会以新的nodejs进程开始。

(defun execute_js_stuff ()
  (interactive)
    (progn
      (save-buffer)
       (let ((nodejs_project_dir (node_js_project_path
                (file-name-directory (buffer-file-name)))))
    (if nodejs_project_dir
        (with-current-buffer (find-buffer-visiting (concat nodejs_project_dir "app.js"))
          (comint-simple-send (get-process "nodejs") (buffer-string)))))))

因此添加了一些代码来删除进程缓冲区，然后重新启动它。但它不起作用。即创建了nodejs进程缓冲区，但app.js缓冲区的内容未发送到nodejs缓冲区。任何可能出错的想法。

(defun execute_js_stuff ()
  (interactive)
    (progn
      (save-buffer)
       (let ((nodejs_project_dir (node_js_project_path
                (file-name-directory (buffer-file-name)))))
    (if nodejs_project_dir
        (with-current-buffer (find-buffer-visiting (concat nodejs_project_dir "app.js"))
          (if (get-process "nodejs")
          (progn (delete-process (get-process "nodejs"))
             (kill-buffer "*nodejs*")))
          (nodejs-repl)
          (comint-simple-send (get-process "nodejs") (buffer-string)))))))
