setting frame size with C-5 2 - emacs 30.5

setting frame size with C-5 2 - emacs 30.5

[H.-J. Heitländer]

Hi there,

since several months the behavior of C-5 2 has changed (for me).

Somehow the new frame only is 16 char wide and 6 lines high. (text window).

Additionally the variables "frame-char-width" resp. "frame-char-height" 
don't seem to be defined.

I'm on "debian testing" with wayland (xwayland) as the display 
protocol(?) Is there a way to set the size of a new frame generated by 
C-5 2?

Searching the docs/internet did not give any result so any help is welcome.

TX in advance

Heiner

They are functions, `frame-char-width' and
`frame-char-height'.

Here (frame-char-width) is 1 and (frame-char-height) is
also 1.

Found it at last (stupid me)

Chatgpt: write emacs elisp function  which sets the new frame size to 65 
w and 33 h

answer: (with small edits)

(defun KM-make-frame ()
   "New frame and set size to w 65, h 33
   "
   (interactive)
   (let ((old-frame (selected-frame))
     (new-frame (make-frame)))
     (select-frame new-frame)
     (set-frame-width new-frame 65)
     (set-frame-height new-frame 33)
     (select-frame old-frame)
     )
   )

Outstanding is the problem with the irritating behaviour of C-5 2. But 
we'll get to that (at some time)

TX to all

Eeek. Chatgpt writes Lisp parehntheses as if they were Javascript
curlies. Go away! go away!
