1. emacs -Q
2. Type `M-x glo TAB' and at the completion "M-x global-" type TAB again,
making a *Completions* buffer pop up.
3. Type `v TAB', yielding the completion "M-x global-visual-line-mode".
=> The window that had been displaying the *Completions* buffer now
displays the *Messages* buffer.
AFAICT this is due to the following cond clause in bury-buffer (which is
called by minibuffer-hide-completions):
((not (window-dedicated-p))
(switch-to-prev-buffer nil 'bury))
Only after typing RET in the minibuffer to accept the completion is the
window that had been displaying the *Completions* buffer and now
displays the *Messages* buffer deleted; in Emacs 23.2 it is deleted as
soon as the sole completion is displayed in the minibuffer. Commenting
out the above clause restores the 23.2 behavior. But this presumably
has bad effects elsewhere.
(Interestingly, the C code of bury-buffer prior to the move to Lisp in
revision 104559 (and long before that) has the equivalent of the above
clause.)

Presumably `minibuffer-hide-completions' should iconify a standalone completions frame while deleting a split-off completions window. So maybe the following DTRT: (defun minibuffer-hide-completions () "Get rid of an out-of-date *Completions* buffer." ;; FIXME: We could/should use minibuffer-scroll-window here, but it ;; can also point to the minibuffer-parent-window, so it's a bit tricky.

(switch-to-prev-buffer window 'bury))))))) > (Interestingly, the C code of bury-buffer prior to the move to Lisp in > revision 104559 (and long before that) has the equivalent of the above > clause.) ISTR that completion windows were dedicated then and typing "v TAB" would trigger the following code in `minibuffer-completion-help' ;; If there are no completions, or if the current input is already the ;; only possible completion, then hide (previous&stale) completions. (let ((window (and (get-buffer "*Completions*") (get-buffer-window "*Completions*" 0)))) (when (and (window-live-p window) (window-dedicated-p window)) (condition-case () (delete-window window) (error (iconify-frame (window-frame window)))))) which I can't find anymore.

In Emacs-23, marking the window as dedicated via display-buffer-mark-dedicated was handy but indeed had the disadvantage of preventing the window's reuse by display-buffer. I think in Emacs-24 this disadvantage is less serious because the completion code is a lot more careful to not leave the *Completion* displayed too long. So making display-buffer-mark-dedicated work (which we need to do in any case) should be all that's needed to fix the bug. But of course, if we can get the *Completions* window/frame deleted without marking it as dedicated, that'd be fine as well. Stefan ^ permalink raw reply [flat|nested] 23+ messages in thread

We could give `quit-window' a third argument telling it to iconify the frame instead of deleting it or add an option to deal with this case. Since I still intend to eventually replace window excursions by `display-buffer' + `quit-window' (which will probably take years) some general pattern would be useful anyway. martin ^ permalink raw reply [flat|nested] 23+ messages in thread

That's a problem of quit-window. I know that some users like this behavior, but making the distinction based on whether the code happened to use quit-window instead of bury-buffer is wrong, IMO. Both bury-buffer and quit-window should hide dedicated frames in the same way, either both by iconifying, or both by deleting the frame (and they should share the same code to do it). This shared code can provide a hook to let the user choose how the frame gets hidden, but the default should be to iconify since that's how it's worked until now (and also because I think it's a safer default, in the sense that iconifying throws away less information than deleting the frame). >> But of course, if we can get the *Completions* window/frame deleted >> without marking it as dedicated, that'd be fine as well. > We could give `quit-window' a third argument telling it to iconify the > frame instead of deleting it or add an option to deal with this case. An argument doesn't seem right, since the choice doesn't depend on the caller, AFAIK, but on the user. > Since I still intend to eventually replace window excursions by > `display-buffer' + `quit-window' (which will probably take years) some > general pattern would be useful anyway. Yes, we agree on this overarching goal, tho I think the issue is not so much save-window-excursion (which generally needs to be solved by changing the code so it doesn't call display-buffer at all) but rather "stash current-window-configuration + set-window-configuration".

With emacs 23 help frames are deleted by default. So if I interpret you strictly, `quit-window' should iconify a dedicated frame and delete a non-dedicated one. Is that correct? Basically, it would be nice to get rid of either `bury-buffer' or `quit-window'. Having two functions do approximately the same thing is neither reasonable for developers nor for users. martin ^ permalink raw reply [flat|nested] 23+ messages in thread

No. Either both are deleted or both are iconified, since (again) it is mostly a choice that depends on the general window-manager usage and user preference. > Basically, it would be nice to get rid of either `bury-buffer' or > `quit-window'. Having two functions do approximately the same thing is > neither reasonable for developers nor for users. I think both are in fairly wide use, so getting rid of one of them is not really an option.

Provide a user option. (And removing is not "hiding". And even hiding does not leave behind little icons.) > but the default should be to iconify since that's how it's > worked until now Oh, that's rich. If you resist bug reports long enough, sure, you can then claim that "that's how it's worked until now", and that's the reason it should continue to be the default ("since"). But no, that's not how it worked, even as recently as Emacs 22, IIRC. At least in Emacs 18,...21,22 quitting the debugger, say, does _not_ iconify a dedicated *Backtrace* frame - it simply _deletes_ it - behavior that makes sense. Seems to me this iconification is something that you introduced. Iconifying is hardly "how it worked" before that. emacs -Q ; Emacs 22 (setq special-display-regexps '("[ ]?[*][^*]+[*]")) M-: (/ 0) q ; in buffer *Backtrace*. Poof - the frame is _deleted_. So by your logic, "since" that's _not_ how it worked throughout Emacs's history until you introduced the iconification bug/feature, the traditional default behavior should be restored: delete the frame. > (and also because I think it's a safer default, in the > sense that iconifying throws away less information than deleting the > frame). You did add "in the sense that", but it's not about _safety_. Deleting a frame does not destroy any important information (buffer/file content etc.). And nothing prevents you from saving the frame position, shape, and size for your own use - e.g. in a register. Do that in a hook if you like. But the default behavior should simply do what a user expects: _remove_ the frame. That could be done by making it invisible or deleting it. Making it invisible would save all of your precious frame info, BTW. Invisibility, like deletion (and unlike iconification), is instantaneous and unclutters the display, and it would presumably be a reasonable compromise. In principle, it should address both your concerns and mine. Supposedly, there are some bugs associated with invisible frames, but it's not clear just what they are (?). Maybe it's time to find out (and fix them). In sum, invisibility would probably be an acceptable compromise default. Iconifying as default should be a non-starter - a bad idea. > the choice doesn't depend on the caller, AFAIK, but on the user. Which means it should be easily customizable by the user - a user option, not just hooks. ^ permalink raw reply [flat|nested] 23+ messages in thread

Upon Stefan's request this variable was renamed to `frame-auto-hide-function' and is now supposed to specify a function that takes a frame as argument.

I think both `quit-window' and `bury-buffer' should handle this the same way now. So if bug#7368 has not been resolved yet we should be able to display completions in a non-dedicated window and quit that afterwards. martin ^ permalink raw reply [flat|nested] 23+ messages in thread

Better yet, the behavior should be customizable (delete, make invisible, iconify, put on a different tab,...), but the _default_ behavior should simply be to *delete* the frame. 1. The analogy to `delete-window' is `delete-frame', and that is just what the behavior here (at least the default behavior) should be: delete the frame. 2. There is no _need_ to iconify a frame that we no longer need (!). 3. Iconifying, at least on Windows, takes longer and distracts the user, sweeping an animation across the screen. 4. If someone binds the window-manager `iconify-frame' event to do something slightly different then things can be even worse: (define-key special-event-map [iconify-frame] 'foobar) 5. Iconifying puts icons (of one form or another) on the desktop. There is no general need for a *Completions* buffer icon. Occam's razor. Anyone really needing to access buffer *Completions* to see the candidate completions from the _last_ command can just use C-x C-b. 6. If *Completions* is always created as a standalone frame, then there is no need to save an icon for it. The buffer is one thing, the frame/icon is another. If you want the frame always created in the same position with the same size or something (the only argument Stefan has ever given for iconifying, AFAIK), then just _create_ it that way each time. 7. Just because Stefan's own use case prefers iconifying is _no reason_ to hard-code iconifying as the behavior. That's several reasons why iconifying is a bad idea. What's the argument _for_ iconifying? Only this: Stefan likes it. He likes it because it saves the frame position and size. That's the only reason that's ever been given, AFAIK. Position, shape, and size of a standalone frame can be handled at its creation, as is usual in Emacs. There is no need to create an icon just to save that info here. ^ permalink raw reply [flat|nested] 23+ messages in thread
