The intention of the following code is to toggle the display of the mode-line when called repeatedly. Although the mode-line is removed when first called, the mode-line does not show up again. I want the function to toggle the mode-line properly.

(defvar-local ramona-mode-line-rflog nil "Toggle switch for mode-line display.") (defun ramona-mode-line () "TODO." (interactive) (setq-local mode-line-format (if ramona-mode-line-rflog (progn (setq mode-line-format ramona-mode-line-rflog) (setq ramona-mode-line-rflog nil)) (setq ramona-mode-line-rflog mode-line-format) (setq mode-line-format nil))) (force-mode-line-update t))

  • You are setting mode-line-format inside the if and then you are setting it again to the result of the if. Lose the outer setq-local: just keep the if. Commented Dec 1, 2022 at 20:04

I commented:

Just in case my comment is not clear, here's what I mean:

(defun ramona-mode-line () "TODO." (interactive) (if ramona-mode-line-rflog (setq mode-line-format ramona-mode-line-rflog ramona-mode-line-rflog nil) (setq ramona-mode-line-rflog mode-line-format mode-line-format nil)) (force-mode-line-update t))

And BTW, you can set multiple variables with one setq: you don't need progn here. Do C-h f setq for the details.
