[SOLVED] emacs - show the current file in other frame

emacs - show the current file in other frame

I want to do something similar to iswitchb-buffer-other-frame except, set the file name programmatically to be the current frame. (with iswitchb-buffer-other-frame you have to chose the file interactively)

If iswitchb is obsolete, can I achieve that with ido-mode or another package (or straight Lisp)?

How can I do that?

EDIT

Based on the answer of @pickle-rick I adjusted the code to my needs.

I need to use switch-to-buffer-other-window instead of switch-to-buffer-other-frame. I'm not sure why... In my setting, I have 2 frames - each frame has a single window, and I need to move the current buffer to the other frame. But it works!
Also, I populate the original frame with an arbitrary buffer (*scratch*) (to prevent showing the original buffer in the original frame)

Here is my adjusted code:

(defun my-switch-buffer-other-frame ()
  (interactive)
  (switch-to-buffer-other-window (current-buffer))
  (other-frame 1)
  (switch-to-buffer "*scratch*")
  (other-frame 1))

Solution

The ido equivalent is ido-switch-buffer-other-frame, which prompts for interactive selection as well. Here is a simple modification to avoid the prompting, and use the current buffer instead,

(defun my-switch-buffer-other-frame ()
  (interactive)
  (switch-to-buffer-other-frame (current-buffer)))
