how to clear ipython buffer in emacs?

Question

I am running and interactive ipython shell in an emacs buffer using ipython.el. I wonder if there is a way to clear the screen? Since it is not running on a terminal, the import os; os.system('CLS') trick will not work. Thanks.

Answer 1

It looks like ipython is based on comint, which means the following code should work for you (called with M-x my-clear or your favourite key binding):

(defun my-clear ()
  (interactive)
  (let ((comint-buffer-maximum-size 0))
    (comint-truncate-buffer)))

I posted some other options in response to this question.

Answer 2

C-c M-o runs the command comint-clear-buffer (found in inferior-python-mode-map), which is an interactive compiled Lisp function.

It is bound to C-c M-o.

(comint-clear-buffer)

Clear the comint buffer.
