I believe this patch should be much less controversial since it allows users to get the old behavior back and still keeps the same semantics for existing `mouse-wheel-*-event` variables in case some other code still generates such events. It's basically a half-way step between what I proposed at first and the status quot. But I'd like some confirmation that you think it's acceptable, and maybe if you could comment on the FIXME included in there (I needed it for clicks on the tab-bar, but I don't understand that code).

This will simplify the work of packages which can thus just bind their commands to `wheel-up/down/left/right`. * lisp/mouse.el (mouse-wheel-buttons): New custom variable. * src/keyboard.c (make_lispy_event): Adjust for "wheel-clicks" on the tab-bar. * src/xterm.c (x_construct_mouse_click): Add `xi2` argument and obey `mouse-wheel-buttons` variable. (handle_one_xevent): Adjust calls accordingly. (syms_of_xterm): Define the `mouse-wheel-buttons` and the `wheel-up/down/left/right`symbols. * lisp/xt-mouse.el: Don't require `mwheel` any more. (xterm-mouse--same-button-p): Delete function. (xterm-mouse--read-event-sequence): Use `mouse-wheel-buttons`. * lisp/mwheel.el (mouse-wheel-up-event, mouse-wheel-down-event) (mouse-wheel-left-event, mouse-wheel-right-event): Make obsolete.

Fascinating. Is there any way I could get to peek at that code? Also interested in the backstory about why your X11 servers are configured without XInput2. Maybe we should provide a better "reverse" story: with the current patch users can recover their old `mouse-4/5/6/7` events by setting `mouse-wheel-*-event` to nil, but then they lose mwheel-based scrolling (plus a few other bindings, mostly one in completion-preview and one in flymake), so the etc/NEWS entry should describe how to recover that scrolling behavior. Or maybe we should keep `mouse-wheel-*-event` untouched (tho, maybe mark them obsolete) and instead introduce a new set of variables that control the remapping of `mouse-4/5/6/7` to `wheel-*` events. That would provide a smoother transition: users can set those new vars to nil to recover the old behavior. Another benefit is that the new var(s) could hold just the button numbers (i.e. an integer) instead of a symbol, which should simplify the remapping code (both in the `xterm.c` and the `xt-mouse.el` cases).

Can we make some progress here? I converted most of the Lisp code at my organization (where X servers are configured with the input extension disabled) to use wheel events under Emacs 30 and arranged for a modified version of Stefan's patch to be built. Which was incidentally not straightforward to do cleanly, as the code in question assumed that events it received would be pairs of button press and release events, and was very much designed around that assumption. Unfortunately the holidays are in full swing, and conclusions from this cannot be drawn until once enough experience accumulates some time after they end. To complicate matters, users at my site don't often work with Emacs 30, except for a few early adopters.

Hmm... indeed there was a crash here, which I just fixed in the patch below. But with that fix, I do see `wheel-up/down` events on the tab-tab as well. Am I missing something? > Lastly, plenty of old code that binds just the button events will be > broken, Indeed. But that should be a disappearing breed because such bindings never worked under non-X11 GUIs and now they don't work either under X11 builds that use XInput2, which I expect is the vast majority of Emacs=E2=89= =A529 builds in GNU/Linux distributions. > and the code that keeps track of button-down and up events in > read_key_sequence and friends will cease applying to X wheel events. Hmm... the only code I can think of in `read_key_sequence` which cares about button up/down is the code that drops the button down events and the one that turns pairs into drag events. Is that ever useful currently with the `mouse-4/5/6/7` events? No one has lamented this under non-X11 builds so far nor under XInput2, so it seems unlikely to be a problem. > This area has given me a lot of grief over the years (as it has given > you), so I'm reluctant to see any change there, as no matter how well > the argument in favor of its safety is posed, some unforeseen problem > invariably emerges afterwards. There's no doubt that event representation is a delicate/nasty part of Emacs code, but I think it's really a trade-off between possible short-term pain and the longer term simplification of unifying all wheel handling under `wheel-*` events. Also, I think we *will* have go through that pain sooner or later.

I'm still opposed to this for reasons I will try to communicate below. First, there are several logic errors in this patch: > + /* Convert pre-XInput2 wheel events represented as mouse-clicks. */ > +#ifdef HAVE_XINPUT2 > + if (!dpyinfo->supports_xi2) > +#endif dpyinfo->supports_xi2 is no guarantee that exclusively input extension events will be received, but only indicates that the X display supports the input extension. There are several scenarios where it may be true while core events are still delivered to windows, such as a combination of GTK 3 and GDK_CORE_DEVICE_EVENTS=1's being enabled. The correct test of event type is whether x_construct_mouse_click is being called from the XI_ButtonPress or XI_ButtonRelease label in handle_one_xevent. Incidentally, servers with the input extension always assign buttons 4 through 7 to wheel movement. > + Lisp_Object base = base_mouse_symbol (result->code); > + int wheel > + /* BEWARE: `mouse-wheel-UP-event' corresponds to > + `wheel-DOWN' events and vice versa!! */ > + = BASE_EQ (base, find_symbol_value (Qmouse_wheel_up_event)) ? 0 > + : BASE_EQ (base, find_symbol_value (Qmouse_wheel_down_event)) ? 1 > + : BASE_EQ (base, find_symbol_value (Qmouse_wheel_left_event)) ? 2 > + : BASE_EQ (base, find_symbol_value (Qmouse_wheel_right_event)) ? 3 > + : -1; > + if (wheel >= 0) > + { > + result->kind = (event->type != ButtonRelease ? NO_EVENT > + : wheel & 2 ? HORIZ_WHEEL_EVENT : WHEEL_EVENT); > + result->code = 0; /* Not used. */ > + result->modifiers &= ~(up_modifier || down_modifier); > + result->modifiers |= wheel & 1 ? up_modifier : down_modifier; > + } > + } Isn't this insufficient to completely supersede mouse events by wheel events, considering that such events will still be delivered as mouse button events to tab bars? Lastly, plenty of old code that binds just the button events will be broken, and the code that keeps track of button-down and up events in read_key_sequence and friends will cease applying to X wheel events. This area has given me a lot of grief over the years (as it has given you), so I'm reluctant to see any change there, as no matter how well the argument in favor of its safety is posed, some unforeseen problem invariably emerges afterwards.

IIUC Po Lu wasn't favorable to the idea, but maybe seeing the code will make a convert? Beside that, the patch has 2 remaining issues: - Lack of corresponding updates to `etc/NEWS` and `doc/lispref/commands.texi`. - Lack of testing for the left/right remapping. This is *really* necessary because even after (re)reading the various parts of the code that handle horizontal scrolling, I'm still very much unsure if I got the direction right[left?], so if you have a mouse with a horizontal wheel, please compare the `wheel-left/right` events generated with and without building `--without-xinput2`.
