Documentation

If non-nil, a function to produce the minibuffer depth indicator.

The function will be called with one argument, the minibuffer depth, and must return a string to display as indication of the minibuffer depth. If nil, display the depth as a number inside brackets, [NN], with the minibuffer-depth-indicator face.

This variable was added, or its default value changed, in Emacs 28.1.

;;; Commentary:
;;
;; Defines the minor mode `minibuffer-depth-indicate-mode'.
;;
;; When active, any recursive use of the minibuffer will show
;; the recursion depth in the minibuffer prompt.  This is only
;; useful if `enable-recursive-minibuffers' is non-nil.
