emacs - 在 emacs/elisp 中运行 start-process 的过滤结果

Question

我有以下代码来运行 python 并在暂存缓冲区中获取结果。

(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 在暂存缓冲区中给我以下代码。

hello, world from PythonProcess my-process finished

I don't need the last part, as it's not from the python. Is there a way not to get this string or deleting this one effectively?

Trey helped me to get an answer.

(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)

你有没有尝试过

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

这将返回一个字符串，您可以像这样将其插入到暂存缓冲区中:

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