Question

我有以下代码来运行python并在 scratch 缓冲区中获取结果。

(defun hello ()
  "Test, just prints Hello, world to mini buffer"
  (interactive)
  (start-process "my-process" "*scratch*" "python" "/Users/smcho/Desktop/temp/hello.py")
  (message "Hello, world : I'm glad to see you"))
(define-key global-map "\C-ck" 'hello)

python代码如下。

if __name__ == "__main__":
    print "hello, world from Python"

使用C-c k在 scratch 缓冲区中给出了以下代码。

hello, world from Python

Process my-process finished

我不需要最后一部分，因为它不是来自python。有没有办法不得到这个字符串或有效地删除这个字符串？

Trey帮助我得到答案。

(defun hello ()
  "Test, just prints Hello, world to mini buffer"
 (interactive)
  (insert (shell-command-to-string "python /Users/smcho/Desktop/temp/hello.py"))
 (message "Hello, world : I'm glad to see you"))
(define-key global-map "\C-ck" 'hello)

你试过吗

(shell-command-to-string "/Users/smcho/Desktop/temp/hello.py")

这将返回一个字符串，您可以在 scratch 缓冲区中插入，如下所示：

(with-current-buffer "*scratch*"
  (insert (shell-command-to-string "/Users/smcho/Desktop/temp/hello.py")))

过滤emacs / elisp中运行启动过程的结果
