等待comint模式缓冲区 [英] Waiting for comint-mode buffer

问题描述

我试图用comint erlang-shell打开一个后台缓冲区，一旦启动，在emacs中运行一个函数（使用distel将其二进制文件发送到erlang节点）。

I'm trying to open a background buffer with a comint erlang-shell, and once it's up, run a call a function in emacs (using distel to send it's binaries to the erlang node).

ie：

...
(let ((args (append (list "-sname" node-name "-pa") path)))
    (get-buffer-create buffer-name)
    (apply #'make-comint-in-buffer node-name buffer-name "erl" nil args)
  (erl-check-backend (make-node-name node-name))
...

问题是当我打电话时，节点尚未启动（epmd没有注册名称），所以它失败了，我猜这是因为下级进程没有机会运行，有没有办法等到comint缓冲区完成安装？

The problem is that when I call distel, the node is not yet up (epmd has no registered names) so it fails. I'm guessing this is because the inferior process has not had the chance to run yet. Is there any way to wait until the comint-buffer has finished its setup?

我尝试接受过程输出缓冲过程的缓冲区作为参数发送到上面的函数，但只是挂起。

I tried accept-process-output on the buffer-process of the buffer sent in as argument to the function above, but that just hung.

推荐答案

在Dave Love撰写的python.el中，使用了以下内容：

in python.el authored by Dave Love the following was used:

(while (progn
     (accept-process-output proc 5)
     (null python-preoutput-result)))
