In emacs lisp how do I silence "Process python-process finished"

Output

In Emacs Lisp, messages like `"Process python-process finished"` are typically generated by the **process sentinel** associated with the process. The sentinel is a function that gets called when the process status changes (e.g., when it finishes). To silence or suppress these messages, you can customize the process sentinel so that it doesn't display the message when the Python process terminates. Here's how you can achieve this: ### Step 1: Define a Custom Sentinel First, define a custom sentinel function that handles process events but suppresses the termination message. You can modify the sentinel to perform other actions if needed or simply do nothing.

(defun my-silent-python-sentinel (process event)
  "A custom sentinel for python-process that silences the finished message."
  ;; You can handle other events here if necessary
  ;; For example, handle errors or other specific process states
  (when (string-match-p "error" event)
    (message "Python process encountered an error: %s" event)))
In this example, the custom sentinel `my-silent-python-sentinel` only displays a message if an error occurs. Otherwise, it remains silent when the process finishes normally. ### Step 2: Assign the Custom Sentinel to the Python Process Next, assign this custom sentinel to your Python process. Replace `"python-process"` with the actual name of your Python process if it's different.

3
(let ((python-process (get-process "python-process")))
  (when python-process
    (set-process-sentinel python-process #'my-silent-python-sentinel)))
This code retrieves the process named `"python-process"` and sets its sentinel to the custom function you defined. ### Putting It All Together You can encapsulate the above steps into a function for convenience: 
1

(defun silence-python-process-finished-message ()
  "Silence the 'Process python-process finished' message."
  (let ((python-process (get-process "python-process")))
    (when python-process
      (set-process-sentinel python-process #'my-silent-python-sentinel))))
Call `silence-python-process-finished-message` after you start your Python process to apply the custom sentinel. ### Example Usage If you're starting the Python process within your Emacs configuration, you can modify the code as follows: 
 1

(require 'python)  ;; Ensure python-mode is loaded

(defun start-silent-python-process ()
  "Start a Python process without showing the finished message."
  (interactive)
  (let ((process (start-python)))  ;; Starts the Python process and returns the process object
    (set-process-sentinel process #'my-silent-python-sentinel)))

;; Bind the function to a key or call it manually
(global-set-key (kbd "C-c p") 'start-silent-python-process)
### Alternative: Temporarily Suppress All Messages If you want to suppress all messages temporarily (not recommended as it affects all messages), you can use the `with-silent-modifications` macro or temporarily disable the `message` function. However, these approaches are more intrusive and can hide other important messages.

(let ((message-log-max nil))
  (set-process-sentinel python-process (lambda (process event)
                                         ;; Custom handling without messages
                                         )))
### Notes - **Process Name**: Ensure that `"python-process"` is indeed the correct name of your Python process. You can check active processes with `M-x list-processes`. - **Error Handling**: The custom sentinel in the example still handles error messages. You can customize it further based on your needs. - **Mode-Specific Configuration**: If you're using a specific Emacs Python package (like `elpy`, `anaconda-mode`, etc.), check its documentation as it might provide built-in ways to customize or silence such messages. By customizing the process sentinel as shown, you can effectively silence the `"Process python-process finished"` message in Emacs.

Output

In Emacs Lisp, the message "Process python-process finished" typically originates from the process sentinel associated with the `python-process`. To silence this specific message, you can customize the process sentinel so that it no longer displays the message when the process finishes. Here's how you can achieve this: ### Step-by-Step Solution 1. **Retrieve the Process:** First, obtain a reference to the `python-process`. This is usually done using the `get-process` function with the name of the process. 

1
2
   (setq python-proc (get-process "python-process"))
2. **Check if the Process Exists:** Ensure that the process exists before attempting to modify its sentinel.

4
   (when python-proc
     ;; Proceed to modify the sentinel
     )
3. **Store the Original Sentinel:** It's a good practice to retain the original sentinel so that you can preserve its behavior for other events. 
1
2
3
4
   (let ((original-sentinel (process-sentinel python-proc)))
     ;; Modify the sentinel
     )
4. **Define a Custom Sentinel:** Create a new sentinel function that ignores the "finished" event but delegates other events to the original sentinel.

   (set-process-sentinel
    python-proc
    (lambda (process event)
      (unless (string-match "finished" event)
        (when original-sentinel
          (funcall original-sentinel process event)))))
5. **Putting It All Together:** Combine the above steps into a single `let` block for clarity and encapsulation.

   (let ((python-proc (get-process "python-process")))

         (set-process-sentinel
          python-proc
          (lambda (process event)
            (unless (string-match "finished" event)
              (when original-sentinel
                (funcall original-sentinel process event)))))))))
### Complete Example Here's a complete snippet you can add to your Emacs configuration (e.g., `.emacs` or `init.el`) to silence the "Process python-process finished" message:

(defun silence-python-process-finished-message ()
  "Silence the 'Process python-process finished' message."
  (let ((python-proc (get-process "python-process")))
    (when python-proc
      (let ((original-sentinel (process-sentinel python-proc)))
        (set-process-sentinel
         python-proc
         (lambda (process event)
           (unless (string-match "finished" event)
             (when original-sentinel
               (funcall original-sentinel process event)))))))))

;; Optionally, hook this function to be called when the process is created
(add-hook 'python-mode-hook
          (lambda ()
            (when (get-process "python-process")
              (silence-python-process-finished-message))))
### Alternative: Using `inhibit-message` If you prefer to temporarily suppress messages within a specific block of code, you can use `inhibit-message`. However, this approach is more general and will suppress all messages within the block, not just the specific "finished" message. 
1
2
3
(let ((inhibit-message t))
  ;; Code that might generate messages
  )
### Notes - **Preserving Other Messages:** The provided solution specifically targets the "finished" message, ensuring that other important messages from the process sentinel are still displayed. - **Process Naming:** Ensure that `"python-process"` matches the actual name of your Python process. You can verify the process name using `M-x list-processes`. - **Customization:** You can further customize the sentinel to handle other events differently based on your requirements. By customizing the process sentinel as shown, you can effectively silence the specific message indicating that the Python process has finished, leading to a cleaner and less cluttered minibuffer experience. --- Feel free to integrate this solution into your Emacs setup. If you encounter any issues or have further questions, don't hesitate to ask!
