In Emacs Lisp, when working with processes such as running a Python script via `python-mode`, you might occasionally see messages like "Process python-process finished" in the minibuffer. If you'd like to suppress these messages, you can customize the behavior of the process sentinel. Here’s a step-by-step guide to silence these messages: 1. **Find the process sentinel function**: The process sentinel is a function that handles process status changes. For Python processes, this is often managed by `python-mode`. 2. **Wrap the sentinel function**: You can wrap the existing sentinel function with your own that suppresses the message. 3. **Set the new sentinel function**: Apply your custom sentinel to the process. Here’s an example of how you can do this:

(defun my-silence-python-process-sentinel (process event)
  "Silence the 'Process python-process finished' message."
  (unless (string-match-p "finished" event)
    (message "Process %s %s" process event)))

(defun my-setup-python-process-sentinel ()
  "Set up the custom sentinel for the Python process."
  (let ((proc (get-process "python")))
    (when proc
      (set-process-sentinel proc #'my-silence-python-process-sentinel))))

;; Add a hook to run this setup function after starting a Python process
(add-hook 'python-mode-hook #'my-setup-python-process-sentinel)

### Explanation: - **`my-silence-python-process-sentinel`**: This function checks if the event message contains “finished”. If it does, it suppresses the message; otherwise, it displays the message. - **`my-setup-python-process-sentinel`**: This function gets the current Python process and sets its sentinel to `my-silence-python-process-sentinel`. - **Hook into `python-mode-hook`**: This adds the setup function to the `python-mode-hook`, ensuring the custom sentinel is applied whenever you start a Python process in Python mode. ### Note: This example assumes that the process name is "python". You might need to adjust the process name depending on your setup. You can check the list of processes using `M-x list-processes` in Emacs to find the exact name of your Python process. This approach should help you suppress the "Process python-process finished" message while still allowing other process-related messages to be displayed.

In Emacs, when you run a Python process or any other subprocess, you might see messages like "Process python-process finished" in the minibuffer. If you want to silence these messages, you can customize the behavior of the process handling functions. One way to silence these messages is to advise the function that handles process completion messages. Here's a way you can achieve this using Emacs Lisp: 1. Define a function to filter out the process completion message. 2. Use `advice-add` to apply this function to the relevant process handling function. Here's an example of how you can do this:

(defun silence-process-finished-message (process event)
  "Silence the 'Process finished' messages."
  (when (and (string-match-p "\\*Python\\*" (buffer-name (process-buffer process)))
             (string-match-p "finished" event))
    (let ((inhibit-message t))
      (message "Process %s %s" process (string-trim event)))))

(advice-add 'comint-postoutput-scroll-to-bottom :before #'silence-process-finished-message)

In this example: - `silence-process-finished-message` is a function that checks if the process buffer name contains "Python" and if the event string contains "finished". If these conditions are met, it temporarily inhibits messages and then outputs a silenced message. - `advice-add` is used to attach this function to `comint-postoutput-scroll-to-bottom`, which is a function involved in the process output handling. Note that this is just one approach. Depending on how you run your Python process, you might need to adjust the buffer name check or the function to which you add advice. If you are using a specific mode for running Python, such as `python-mode`, you might also consider advising the mode-specific process handling functions instead. If you’re not sure which function to advise, you can look at the documentation for the mode you’re using or inspect the source code to find the appropriate function that handles process output or completion.

In Emacs, you can silence the "Process python-process finished" message by customizing the behavior of the process sentinel. The process sentinel in Emacs is a function that gets called whenever there is a change in the state of a process (e.g., when it finishes). Here's how you can suppress the message for a Python process: 1. **Identify the Process**: First, identify the process name. In your case, it seems to be `python-process`. 2. **Set Up a Custom Sentinel**: Write a custom sentinel function that handles process state changes without printing the "Process finished" message. 3. **Assign the Custom Sentinel to the Process**: Attach this custom sentinel to your Python process. Below is an example of how you can achieve this in Emacs Lisp:

(defun my-silence-python-process-sentinel (process event)
  "Custom process sentinel to silence the 'Process python-process finished' message."
  ;; You can add custom handling here if needed
  (when (memq (process-status process) '(exit signal))
    (let ((buffer (process-buffer process)))
      (when (buffer-live-p buffer)
        (with-current-buffer buffer
          ;; Optionally, you can add custom handling here
          ;; for example, killing the buffer, etc.
          )))))

(defun my-setup-python-process-sentinel ()
  "Set up the custom process sentinel for Python process."
  (let ((process (get-process "python-process")))
    (when process
      (set-process-sentinel process #'my-silence-python-process-sentinel))))

;; Call this function after the Python process is started.
(my-setup-python-process-sentinel)

You need to call `my-setup-python-process-sentinel` after the Python process is started. This function retrieves the Python process and sets the custom sentinel `my-silence-python-process-sentinel` to it, which effectively silences the message. If you are using a specific mode or package to run your Python process, you might want to hook into its process start function to make sure the custom sentinel is set up appropriately. For example, if you are using `python-mode`, you could add this to the `python-mode-hook`:

(add-hook 'python-mode-hook #'my-setup-python-process-sentinel)

This way, every time you enter `python-mode`, the custom sentinel is set up to silence the "Process python-process finished" message.

In Emacs, the message "Process python-process finished" typically appears in the minibuffer when a process finishes execution. If you want to suppress or silence this message for a specific process, you can customize the process sentinel. The process sentinel is a function that gets called when the state of a process changes. Here's an example of how you can set a custom sentinel to suppress the "Process python-process finished" message for a Python process:

(defun my-python-process-sentinel (process event)
  "Custom sentinel to silence \"Process python-process finished\" message."
  (when (and (memq (process-status process) '(exit signal))
             (string= (process-name process) "python-process"))
    ;; Process has finished, but we do nothing to suppress the message.
    ))

;; Start your python process and set the custom sentinel
(let ((python-process (start-process "python-process" "*Python*" "python" "-c" "print('Hello, World!')")))
  (set-process-sentinel python-process 'my-python-process-sentinel))

In this example: 1. We define a custom sentinel `my-python-process-sentinel` that checks if the process has finished and if its name is "python-process". 2. We start a Python process using `start-process`. 3. We set the custom sentinel for the process using `set-process-sentinel`. The custom sentinel does nothing when the process finishes, effectively suppressing the default message. If you want to apply this to all Python processes started within Emacs, you might need to hook into the way these processes are started, depending on how you initiate them (e.g., through a specific mode or command). For instance, if you are using `python-mode`, you can advise the function that starts the Python process to set the custom sentinel. Here's an example of how you might do that using advice:

(defun my-set-python-process-sentinel (orig-fun &rest args)
  "Advice to set a custom sentinel for Python processes to silence finish message."
  (let ((process (apply orig-fun args)))
    (when (and process (string= (process-name process) "python"))
      (set-process-sentinel process 'my-python-process-sentinel))
    process))

(advice-add 'run-python :around #'my-set-python-process-sentinel)

In this example: 1. We define an advice function `my-set-python-process-sentinel` that wraps around the original `run-python` function. 2. We apply the advice using `advice-add`, ensuring the custom sentinel is set for Python processes started by `run-python`. You may need to adjust the function and process names according to your specific setup or the mode you are using.

In Emacs Lisp, the message "Process python-process finished" is typically generated by the process sentinel function associated with the Python process. To silence this message, you can create a custom sentinel function that suppresses it. Here's a step-by-step approach to achieve this: 1. Define a custom sentinel function that ignores the "finished" message. 2. Attach this custom sentinel function to the Python process. Below is an example of how you can do this:

(defun my/python-process-sentinel (process event)
  "Custom sentinel for Python process to suppress 'finished' message."
  (unless (string-match-p "finished" event)
    (message "Python process event: %s" event)))

(defun my/silence-python-process-finished ()
  "Silence the 'Process python-process finished' message."
  (let ((python-process (get-process "python")))
    (when python-process
      (set-process-sentinel python-process 'my/python-process-sentinel))))

;; Add a hook to run this function after starting the Python process
(add-hook 'inferior-python-mode-hook 'my/silence-python-process-finished)

Explanation: 1. `my/python-process-sentinel`: This custom sentinel function checks if the event string contains the word "finished". If it does, it ignores the message; otherwise, it prints the event. 2. `my/silence-python-process-finished`: This function retrieves the Python process (assuming its name is "python") and sets the custom sentinel function for it. 3. `inferior-python-mode-hook`: This hook ensures that the custom sentinel function is set whenever an inferior Python process is started. Add this code to your Emacs initialization file (e.g., `~/.emacs` or `~/.emacs.d/init.el`), and it will suppress the "Process python-process finished" message for you. If the name of the process is different or you are using a specific Python mode, you might need to adjust the process name and hook accordingly.
