And you haven't explained what you consider end-of-text. Moreover, the assumption that fit-window-to-buffer ignores non-[:graph:] characters is false. This function counts everything that's displayed as some kind of glyph, no matter what kind of character that is. What you see in the case you described, when this function is called with point at EOB, is the normal Emacs display operation: after the command completes, if point is outside the window, Emacs scrolls the display to bring point back into view. The trigger for that scrolling is the fact that you positioned point at EOB. So don't.

With emacs -Q the buffer is recentered after fit-window-to-buffer, and half of it (with your example) is visible. If you want to see the whole buffer in that case, you can one of the following lines to your init file: (advice-add 'fit-window-to-buffer :before (lambda () (or (< (point) (point-max)) (previous-line)))) (advice-add 'fit-window-to-buffer :after (lambda () (enlarge-window 1))) But that still does not guarantee that after fit-window-to-buffer the whole buffer will be visible, if you press C-l and repeat fit-window-to-buffer only the second half of the buffer is visible. If you want to handle that case as well, you can use this for example: (advice-add 'fit-window-to-buffer :after (lambda () (and (= (count-lines (point-min) (point-max)) (1- (window-height))) (or (< (point) (point-max)) (forward-line -1) t) (set-window-start nil (point-min))))) > > Basically, after `fit-window-to-buffer' is called, the following should > evaluate to t: > > (and (pos-visible-in-window-p (point-min)) > (pos-visible-in-window-p (point-max))) > That would only be possible under the condition you mention: "when the buffer is smaller than the window".

Violating it, albeit in a corner case, is, IMO, a bug. I think you misunderstand the contract: the function fits the window to the buffer text, which doesn't include the (imaginary) place beyond the last character. When you are are EOB, doesn't "C-x =" say something like point=N out of N-1 (EOB) ? Do you see what I mean by "beyond the last character"? > I am not sure how this should be fixed It shouldn't be fixed, because it ain't broken.

As I said, if `fit-window-to-buffer' has a "contract", it's the invariant above. Violating it, albeit in a corner case, is, IMO, a bug. I am not sure how this should be fixed - either by allowing the point to be outside of the window (if that is possible) or extending the window by 1 extra line in this corner case - but it _should_ be possible to fix it.

Yes, but by having point at EOB (and assuming the last line ends in a newline), you've made point be outside of the window's text. Instead of moving point to the end, move it to last line of the buffer, and then "C-x w -" will leave the entire buffer text on display. So I don't think there's a bug here. > Basically, after `fit-window-to-buffer' is called, the following should > evaluate to t: > > --8<---------------cut here---------------start------------->8--- > (and (pos-visible-in-window-p (point-min)) > (pos-visible-in-window-p (point-max))) > --8<---------------cut here---------------end--------------->8--- No, because point-max is after the last newline, and thus effectively one line beyond the window's text.

The window shrinks, but it is empty - the whole buffer is above. One has to move the point to the beginning-of-buffer to make the buffer visible. I think this is a bug - the window should show the whole buffer; after all this is the raison d'etre of `fit-window-to-buffer', right?
