emacs跟踪一个不可靠的连接

Question

我想运行R一个远程下一个盒子地方 Emacs(我不希望在远程机器上运行的Emacs).

我可以R使用TRAMP以下命令在远程主机上运行:

(let ((default-directory "/user@remote:~"))
  (R))

一切正常,但是当连接remote丢失时,R死亡.这并不好,因为这意味着我必须在重新R启动后重新加载所有数据,这需要时间.

是否有可能告诉TRAMP使用持久终端？(GNU Screen或tmux或Mosh或dtach)

另请参见emacs-develthread tramp:sshx:(screen | tmux).

Answer 1

以下是如何在远程屏幕会话中使用ES运行R:

• ssh到远程主机(在emacs之外)

• 开始屏幕会话

• 分开它

• 在emacs(M-x shell)中打开shell

• 在emacs shell中再次ssh到远程主机

• 恢复屏幕会话(screen -r)

• 开始R.

• 最后使用M-x ess-remote在你启动R的shell缓冲区中将ESS附加到R进程

Answer 2

以下是使用dtach的替代方法:

(defvar R-remote-host "remote-server")
(defvar R-remote-session "R")
(defvar R-remote-directory "~")
(defun R-remote (&optional remote-host session directory)
  "Connect to the remote-host's dtach session running R."
  (interactive (list
                (read-from-minibuffer "R remote host: " R-remote-host)
                (read-from-minibuffer "R remote session: " R-remote-session)
                (read-from-minibuffer "R remote directory: " R-remote-directory)))
  (pop-to-buffer (make-comint (concat "remote-" session)
                              "ssh" nil "-t" "-t" remote-host
                              "cd" directory ";"
                              "dtach" "-A" (concat ".dtach-" session)
                              "-z" "-E" "-r" "none"
                              inferior-R-program-name "--no-readline"
                              inferior-R-args))
  (ess-remote (process-name (get-buffer-process (current-buffer))) "R")
  (setq comint-process-echoes t))

打电话M-x R-remote RET RET RET RET.

这个对我有用.

PS.答案的问题(而不是在问题的要求)是使用EIN与Jupyter.
