The branch 'feature/context-menu' is ready for merging to master.

It was created after the discussion in
https://lists.gnu.org/archive/html/emacs-devel/2021-07/msg00300.html
as a proof-of-concept.

And after testing with different modes, it proved to be flexible enough
to support various needs.

After merging it could be improved further with more development in master.

The branch contains a NEWS entry and changes in the documentation.

I haven't tested the branch, but reading the diff, it looks like an
excellent feature to me.  Looking at the implementation of the stuff in
various modes, I'm wondering whether the interface should perhaps be
tweaked a bit:

+(defun eww-context-menu (menu)
[...]
+  (when (or (mouse-posn-property (event-start last-input-event) 'shr-url)
+            (mouse-posn-property (event-start last-input-event) 'image-url))
+    (define-key menu [shr-mouse-browse-url-new-window]

Perhaps the signature of the context menu functions should be:

+(defun eww-context-menu (menu event)

?

I'm also wondering whether we should add a `context-menu' text property.

To get an event would be nice, but I see no way to do this.
The top function 'context-menu-map' is called by:

  `(menu-item ,(purecopy "Context Menu") ignore
              :filter (lambda (_) (context-menu-map))))

that has no access to the event - an unused argument of lambda above
is just the binding that is 'ignore' in this case.

> I'm also wondering whether we should add a `context-menu' text property.

As soon as such a need arises, a text property could be added as well.
But it seems currently much cleaner is to use a single context-menu
function for every mode.

Could just use `last-input-event', I guess?  But that doesn't really
give us anything better than what we have, so there's probably no point.

Right.  I was thinking that it's pretty likely that all button-like
things are going to grow a context menu, but we can add `context-menu'
later if that turns out to be the case.

It would be easier to make more experiments with code in master,
so now merged the branch to master.

I see the context menu after M-x context-menu-mode.  Thank you for
working on this.

I will see how it works and try to give feedback soon.

Thank you for the great idea of using a list of functions.

Waiting for your feedback.

The raison d'être for the special mode context-menu-mode is to
rebind the default keys optionally.  So it would make sense to bind
context-menu-entry conditionally:

1. to [C-mouse-1] on macOS depending on ‘(featurep 'ns)’;
2. to [down-mouse-3] everywhere else.

in the function body of context-menu-mode.

Additionally, a Buffer menu is accessible from the context menu
when context-menu-functions is customized to contain ‘context-menu-global’.

After trying to remove it altogether, there is no title at all,
but maybe it's platform-dependent (I tested on GTK):

Could you please provide a test case?  Because I've thoroughly tested
“Find Definition” to apply where the click occurred, and it works as expected.

We'd like both bindings to work on macOS (the user could have a mouse with a right button) but that should be doable.

After your suggested change I still get the "Select" title; needs to be investigated further.

Yes it works for elisp, because its xref backend is simplistic enough to just accept the symbol given as argument. An example of a package where it doesn't work is merlin which is rather more sophisticated and wants to find the exact context so that it can find the right definition, so it ignores the argument.

It would be useful to do this for elisp as well, so that it would work for local variables etc.

I see you already pushed this, but it's a bad idea: it makes ugly
context menus on TTYs (and AFAIU also on non-toolkit X builds): these
_require_ the menu name because they display a caption which looks bad
with an empty name.

I don't really understand the original complaint: we have similar
captions on the menu shown by C-mouse-3 in the default configuration:
do macOS users want those to be removed as well?  If not, what is the
difference?

That "Select" is probably macOS specific, I don't see it here.

We definitely do but few people use that (rather useless) menu so its appearance doesn't matter much.
If the goal here is to make a genuinely useful context menu that people actually want to use, then it should look like one.

I'm probably wrong, but Windows context menus haven't titles either as I remember it and they would look quite out of place on that platform as well.

I guess the presence of the title should be platform-dependent.
For example, without a title it looks great on the GTK build.

OK, so I guess this change should be done only on macOS (but not on
TTY frames displayed on macOS).

Well, C-mouse-3 shows the caption of a menu on MS-Windows, so I see no
problem with showing "Context menu" there (or any other string, if we
find a better one, actually).  That serves as a small description of
what this menu is about.

What happens if the GTK build displays a TTY frame?  Isn't the menu
definition global, and thus doesn't distinguish between frame types?

Come to think about it: aren't menu keymaps _required_ to have this
string?  The ELisp manual says:

   -- Function: make-sparse-keymap &optional prompt
       This function creates and returns a new sparse keymap with no
       entries.  (A sparse keymap is the kind of keymap you usually want.)
       The new keymap does not contain a char-table, unlike ‘make-keymap’,
       and does not bind any events.

	    (make-sparse-keymap)
		⇒ (keymap)

       If you specify PROMPT, that becomes the overall prompt string for
       the keymap.  You should specify this only for menu keymaps (*note
       Defining Menus::).  A keymap with an overall prompt string will
       always present a mouse menu or a keyboard menu if it is active for
       looking up the next input event.

Stefan, did we remove this requirement at some point, or is it still a
requirement?

If this is still needed (and it seems to be, at least on some frame
types), I guess it's the code which produces native menus that wants
not to have this caption (e.g., on macOS and GTK) -- that code should
ignore this string and not stuff it into the native menu widget.  But
internally the menu name should still be present in the Lisp data
structure.

The menu definition is constructed dynamically, so it possible
to set the title when (framep (selected-frame)) returns t on tty.

OK, but as I wrote elsewhere, I think the string should always be
present, and if some GUI toolkit wants to ignore it, it should avoid
putting it into the native menu structure when it creates the menu
widget(s).  The Lisp data should remain the same, IMO.

If memory serves it's used (as the title) for the non-toolkit menus and
it's not used for the toolkit menus, but the reality is probably less
clear cut than that.

That's also my recollection.  In particular TTY menus actually
_expect_ to find a meaningful string there.

So I think we need to reinstate the name in the context menus (though
perhaps we could come up with a better name than "Context menu"), and
if some toolkit wants to ignore it, they should do it when they create
the menu widgets to show the menu on the screen.

GUI toolkits can't ignore titles for all menus.  Some menus should be
displayed with a title for all toolkits.  The context menu is special.
Nowadays everyone is accustomed to down-mouse-3 popping up a context menu
without title.  But other Emacs-specific menus that are not familiar to users
such as mouse-buffer-menu bound C-<down-mouse-1> should display a title
for all toolkits to explain to the user what choice the menu presents.

Which popup menus have titles that cannot be ignored, and why?

If we want some titles to behave in special ways, we could put a text
property on the title string to mark those titles that should get
special treatment.  That is better than removing the title, and
certainly better than removing it based on the frame type, because
then Lisp code which handles the menu keymaps will need to be prepared
to handle both kinds of menu keymaps, the ones with a title and ones
without it.  It is also against the documented practice.

So let's please reinstate the title, and use properties or some other
mechanism to mark the title strings that need special handling in some
circumstances.

Thanks.

Having actually read the doc strings I see that xref backends are supposed to define `xref-backend-identifier-at-point` which can stuff any information it needs in a property of the string it returns, as sort of a semi-covert channel to `xref-backend-definitions` etc. Sorry about the unfounded complaint.

Would adding `xref-find-references-at-mouse` be handy for use in the context menu?

An example of such menu is mouse-buffer-menu bound to C-<down-mouse-1>
where the user might wonder what do these menu items with mode names mean?

Using a text property would be a good solution.  Should then
the NS-specific "Select" title be removed in menu.c
when the title has a special text property?

If the existing `xref-backend-identifier-at-point` can't be reused
by adding a new optional arg `click`, then a cleaner solution
would be to add `xref-backend-identifier-at-mouse` indeed.

That's moot for macOS since C-mouse-1 will be used for the context menu. (Proposed patch attached.)

In macOS/NS, "titles" as disabled menu entries simply do not exist in the GUI vocabulary and look alien, amateurish, confusing or wrong. The menu is expected to be understood in its context of activation.

Where menus have titles, it's the corresponding entry in the parent menu (or menu bar). They are never named "something Menu" because that would be silly; typically it's a verb, or a noun setting a context for the entries in the sub-menu. For a menu of buffers to switch to, the title (if any) might be "Switch to buffer", "Buffer", "Switch to" or similar.

OK, but I still don't think I fully understand how context menus are
different.  Are we sure the user will immediately understand the
purpose of the context menus, but not of a buffer-menu?

I'm not sure I understand what is the NS-specific "Select" title.  Can
you point me to the relevant code?

I fully agree. I'll see what I can do.

Meanwhile I'm pushing the C-mouse-1 change since it seems to be in line with the intent of context-menu-mode.

Context menus displayed up by down-mouse-3 are ubiquitous nowadays,
they are everywhere, and the users expect them without a title,
unlike Emacs-specific menus unfamiliar to most users.

On emacs-devel Ergus proposed to add such bindings to a new
context-menu-mode-map.  Do you think this is feasible?

`xref-backend-identifier-at-point` is a generic function implemented by each backend; a new function appears cleaner. Suggested patch attached!

More discoveries and questions:

* If I start emacs -Q and enable context-menu-mode, right-clicking on an identifier in an elisp buffer still doesn't produce the Find Definition entry, presumably because xref hasn't been loaded. Shouldn't it be arranged to be autoloaded somehow, which is how xref works when invoked by keystrokes?

* `xref-make-match` requires (contrary to its doc string) its LOCATION argument to be of type `xref-file-location`, but some backends may only be able to make an `xref-buffer-location`. Would anyone object to changing the :location slot of `xref-match-item` to have type `xref-location`? I don't see how it could hurt.

Quite possibly, but the proof is in the pudding.

So if some menu is popped up by mouse-3, it is automatically
considered ubiquitous and expected?  I really doubt that, but I won't
argue any further.

OK, but where in that patch is the NS-specific "Select" title that
should be removed?

I'm not Juri, but the following patch removes the default "Select" title used by the NS port. Not sure why it was ever added -- perhaps something Gnustep-specific? Works well with Cocoa in any case.

I wonder what could be the reason for that. It would seem the menu 
should handle autoloaded commands fine. Even the visibility predicate 
should work: xref-find-backend is autoloaded as well.

Try rewriting it with a let, to ensure that xref-find-backend is called 
first:

(let ((backend (xref-find-backend)))
   (xref-backend-identifier-at-point backend))

Makes sense to me, seems like an accident. I've done this change 
locally, no obvious bugs fell out.

I’m new to 28 and it will take a while to adopt to it.
I’m sending comments so far.

* Binding

I suggest to assign [drag-mouse-3] as well, as shown below.

(define-key map [mouse-3] context-menu-entry)
(define-key map [drag-mouse-3] context-menu-entry)
 
On Mac, I suggest to assign [C-double-mouse-1] as well as shown below.

(define-key map [C-down-mouse-1] #'ignore)
(define-key map [C-mouse-1] context-menu-entry)
(define-key map [C-double-mouse-1] context-menu-entry)
(define-key map [C-triple-mouse-1] context-menu-entry)
(define-key map [C-drag-mouse-1] context-menu-entry)

* Error detection system

It is good if the context-menu system is ready for
an error that occurs on one of context-menu-functions.
For now, when there is error, Emacs only tells
`<mouse-3> is undefined'.

* Long click system

It’s time to discuss long-left-click also as trigger to
show context menu.

https://lists.gnu.org/archive/html/emacs-devel/2020-09/msg01277.html

* Open by other frame

File would be opened by this window. Sometimes I want to open it by
other frame.  It is good if which window to open, is selectable after
showing context-menu. I do not know how to do so.

* Details

It is handy to have buffer menu when right click mode bar.

(define-key map [remap buffer-menu-open] context-menu-entry)

Also it is handy to have frame menu when right click title bar.
I do not know how to do so.

Also it is nice to show word candidates by ispell when click a word.

** context-menu-region

All commands belong to `Edit' in menu bar.
I think `context-menu-edit' sounds better.

Isn't it better to use `menu-bar-edit-menu' as a source rather than
create a menu from scratch?

On paste when there is a region and delete-selection-mode is t, the
region should be replaced by the text.

** no multiple horizontal lines

Sometimes I see double lines on the context menu.  I think that there is
no useful case to have double lines.  To allow only one horizontal line
would look cool.

** reuse existing menu

I cannot figure out how to include pre-existing menu such for
(mouse-buffer-menu-map).  To lean how to manipulate menu is not easy.
It's nice to have an example something like below (does not work).

  (defun context-menu-buffer (menu)
  "Add a buffer menu entry to MENU."
    (let ((map (mouse-buffer-menu-map)))
      (define-key-after menu [buffer] map))
    menu)

GNUstep, and I believe NEXTstep and old school macOS, allows you to
"tear off" menus and leave them on screen as sort of custom toolbars.
Hence the title on each menu.

Emacs doesn't support this with the main menus (it was the source of a
crash, so I removed it), but I don't know if it's something we should
support. I suspect not because once Emacs updates the menus it
probably can't handle clicks on old ones.

Thank you, I pushed the removal of the default "Select" title: titles will still be there if given explicitly. If this causes trouble for Gnustep, then we'll reinsert the default title for that platform only.

It was just a (featurep 'xref) test which didn't seem to be needed; as you say, all the functions involved are autoloaded and I have verified that xref will indeed be loaded when the menu is used the first time. Pushed to master.

Thank you, fixed on master.

Also pushed:

* Previous patch that adds "Find References" to the menu; it seemed to be the right thing to do.
* A fringe arrow is now used to indicate the current position in the *xref* buffer
* Messages added to assuage the boredom of users while searching for references. Could be moved, rephrased, made optional or removed altogether, but it did look a lot better than freezing for a long time.

I think it may be confusing that the arrow doesn't appear immediately
after M-., only when you switch from the XREF buffer.

Thanks.

I don't quite follow -- M-. typically doesn't create an *xref* buffer at all; when it does, it does not follow any of the matches found therein.

The arrow indicates the latest match reference that has been followed to its target, in the same way as in compile, grep and occur buffers. In neither of these buffers the arrow appears immediately.

Oh, so it's only appearing when the tag is shown?  Confusing... but I
guess we will have to live with that.

Got it.

There is no need to bind [drag-mouse-3] because [down-mouse-3] is bound.

I leave this for the users of Mac to decide what would be better on Mac.

I agree, a better error reporting would be nice.  Patches welcome.

I tried to implement this, but soon found that long-left-click is unusable,
because such artificial delay is a hassle - no one would have
patience to wait even half a second until the menu finally appears.
But this could be implemented anyway when users will demand this.

Sorry, I don't understand what menu do you mean, maybe in Dired mode?

I don't see where buffer-menu-open currently is used on the mode-line.

This gives the error "void-variable map".

I think this is a good idea.

I do not know how to do this for the frame title bar.
But currently I'm doing this for the tab bar.

Maybe like flyspell-mode?

> ** context-menu-region

I already tried to use your idea to name it `context-menu-edit'.
But the problem is that other functions like context-menu-undo are also
related to editing.  OTOH, some items in context-menu-region don't do
editing such as "Select All" is not editing, "Copy" is not editing, etc.

> Isn't it better to use `menu-bar-edit-menu' as a source rather than
> create a menu from scratch?

I already tried this idea but this menu is already available
in the global menu that already can be enabled by adding
context-menu-global to context-menu-functions.
But maybe `context-menu-edit' could be added as well
from `menu-bar-edit-menu'.

Please explain how the region should be replaced by the text,
when mouse-yank-at-click or mouse-yank-primary is used
to paste where the mouse is clicked.  Should it delete the region
and paste where mouse is clicked on another part of the buffer?
What if the mouse is clicked in another window?

Right, double separators should be removed.

Adding the existing menu is not easy.  There are some examples in
context-menu-global, context-menu-local, context-menu-minor.

What is confusing? We do the same in Grep and Compilation.

That's not exactly the same, because with M-. I already asked to show
me a definition.  Anyway, not worth an argument.

Perhaps your complaint is instead about no definition being shown, even 
though you feel like you already asked Emacs to show one (which the 
fileloop UI does).

Yes.  But that ship has sailed long ago.

This is something I wanted to have for a long time.  I do not have

I think this is useful especially on laptop computer with Mac.
As inferred on other posts laptop computer with Mac does not have
mouse-3.  However, it is possible that I’m the only one.

`ffap-at-mouse’ will open a file under pointer on `this window’.
Randomly I want to open it by `other frame’.
It’s good if I can choose open the file on `this window’ or `other frame’.
Is there a way to detect meta key pressed when select one of menu items?

This suggestion may be unrelated to context-menu.
On mode bar, both mouse-1 and mouse-3 switches buffer. 
I think mouse-3 should show something like (mouse-buffer-menu-map).

OK.

OK.  I only wanted to suggest reducing maintenance cost.

When there is a region and yank text by `C-y’, the text would
be replaced.

I think when there is a region and point in on region, region
should be replaced by text.  No?

OK.  I did not know it is not easy.
I cannot find guid line how the menu should be created.
Do you know where to look?

Recently Mattias bound C-mouse-1 to use instead of mouse-3 on Mac.

There is no way to detect meta key.  But you can create a new command
to open in a new frame, and add this command to the menu.  Or use
the existing `ffap-other-frame'.

Yes, this would be useful.

mouse-yank-at-click is intended to paste where you click.
So when there is a region, and you click mouse-3 at some other position
where you want to paste, and select "Paste" from the context-menu,
it's unclear what to do with the region.  It makes no sense
to delete the region, when you paste at the clicked position
outside of the region, but not on the region.

Please see more in mouse-yank-at-click and mouse-yank-primary
that contain such comment about the need to deactivate the region:

  ;; Without this, confusing things happen upon e.g. inserting into
  ;; the middle of an active region.
  (when select-active-regions
    (let (select-active-regions)
      (deactivate-mark)))

>>> I cannot figure out how to include pre-existing menu such for
>>> (mouse-buffer-menu-map).

Actually, the right function to use is (mouse-buffer-menu-keymap)
instead of (mouse-buffer-menu-map).

> I cannot find guid line how the menu should be created.
> Do you know where to look?

Good documentation is in (info "(elisp) Defining Menus").

Only if the chief maintainer thinks that the UI must be frozen in time.

We could add an option, at the very least.

An option to display the first match right away will be most
appreciated, thanks.

I started to understand the system.
A plug-in to list frames would be something like this.
I think it is good to have interface to basic utilities such for
recentf and bookmarks.

(defun context-menu-frame (menu)
  "Add MENU a list of frames."
  (let (frame-map)
    (dolist (frame (visible-frame-list))
      (let ((nickname (cdr (assoc 'name (frame-parameters frame))))
            (cmd `(lambda nil (interactive) (funcall 'menu-bar-select-frame ,frame))))
        (push (vector nickname cmd :active (not (equal frame (selected-frame)))) frame-map)))
    (push ["--" ignore] frame-map)
    (push ["New" make-frame-command] frame-map)
    (setq frame-map (reverse frame-map))
    (push "Frames" frame-map)
    (easy-menu-add-item menu nil frame-map)
    menu))

There are endless possibilities in creating various submenus.
So the default set of submenus is limited only to already existing menus:

context-menu-toolbar copied from the tool-bar
context-menu-global copied from the global menu-bar
context-menu-local copied from the local menu-bar
context-menu-minor copied from the minor-modes menu-bar
context-menu-vc copied from the vc menu
context-menu-undo copied from the Edit menu
context-menu-region copied from the Edit menu

So if you can find an existing menu, it could be added.
But I can't find the existing menu with a list of frames.
There are only the existing menu with a list of buffers
like you proposed (mouse-buffer-menu-map) from [C-down-mouse-1],
but better to use (mouse-buffer-menu-keymap),
so now context-menu-buffers is added to the default list.

The remaining existing menu is 'mouse-appearance-menu' bound to
[S-down-mouse-1].  I don't know if it's significant enough
to be added to the default list?

Also you proposed a good idea to have a frame menu when
right clicking on the title bar.

So we even have a precedent, very good.

Could you both check out the attached patch?

Together with (setq xref-auto-jump-to-first-definition t)

Questions for feedback:

1. Does the new behavior work okay window management-wise (it does 
occupy +1 window, after all)?

2. Should this setting also extend to other commands like 
xref-find-references? Asking for personal preferences here.

* flyspell menu

It is handy to show 'flyspell-correct-word when click on typo word.
However, menu is embedded inside of pre existing
'flyspell-correct-word and it is hard to collect menu.  Since
popup-menu interface can accept both menu and function with `e', it's
good to utilize 'flyspell-correct-word.

How about something like below to interrupt evaluation of
context-menu-functions in the middle when one of
context-menu-functions returns symbol instead of menu?

Thanks, adapting flyspell to use the context menu is our next priority.
But it seems interrupting evaluation is too hackish solution, and it still
uses x-popup-menu.  Would it be possible for flyspell to put its context
function to the end of context-menu-functions, and then replace all
previously added menus with own menu that contains word corrections?

Here is the first step that adds support for overlay-local context-menu,
and removes the recently added 'flyspell-use-mouse-3-for-menu'.
But 'flyspell-context-menu' still returns 'flyspell-correct-word'.

I invite you or anyone else to refactor 'flyspell-correct-word' and
related functions to return a keymap menu where every menu item
is bound to a function that calls flyspell-do-correct with an argument
that is a correct word.

Not sure I understand the question: we pop up an additional window
when there are more than one candidate even without this option, so
why do you say "+1 window"?  Maybe you had some recipe in mind that I
didn't try?

> 2. Should this setting also extend to other commands like

Not necessarily.  Perhaps xref-auto-jump-to-first-definition should be
tri-state, to allow users to request the same with
xref-find-references as well?

Very good. Let's now discuss a couple of minor alterations. We can 
always go back to this patch if we don't decide on anything better.

I think I remember now why it didn't make sense to me to have this 
behavior OOTB: I think the main goal of the user who calls 
xref-find-definitions is, usually, to pick one definition they wanted to 
visit. Which also means having the xref buffer dismissed at the end.

With the patch under discussion we automatically jump to the first 
location. We can even iterate through locations with 
next-error/previous-error (M-g M-n/M-g M-p). But to close 
(quit/kill/etc) the list of locations, you have to switch back to its 
window and press 'q'. Didn't that look like a bother to you?

Here's how it could look instead:

1. When you press M-., the first location is "shown", but not jumped to. 
The focus remains on the Xref window, with point on its first item (the 
arrow beside it is visible, like you wanted). Location is visible in the 
other window, and we can either visit it and dismiss the Xref buffer 
(with 'C-u RET'), simply visit it with 'RET', or look at the other 
locations with 'n'/'p'.

For this to work, the patch will need to change xref--auto-jump-first, 
swapping

+  (xref-next-line-no-show)
+  (xref-goto-xref))

for

+  (xref-next-line)

The new option's name would probably be different too.

And you could also use a "transient" show-definitions-function like:

(setq xref-show-definitions-function
       #'xref-show-definitions-buffer-at-bottom)

Then you'd only need to press RET in the results buffer to jump and 
dismiss the results buffer.

2. Simply have point move to the first location in the list (rather than 
remain on the group name). From there, the user can press 'C-o' to show 
the location without visiting, or 'RET', or 'C-u RET' like described 
above. I understand this does not fit your prior workflows, but it does 
require the least number of button presses in the scenario "go to the 
first location and dismiss the Xref buffer", especially in combination 
with the (setq xref-show-definitions-function ...) form above.

It's "+1 window" compared to how 'find-tag' worked/works, which I assume 
is the target.

So it's still not the same behavior.

Sure. Or we can have two variables, especially if we end up cramming 
different variations of behavior into them.

We can do a lot of things. What would help, is better knowledge about 
what people *want* to do.

I clicked mouse-3 on the Flymake mode-line indicator expecting a context menu,
but mouse-3 abruptly closed the current buffer.  This can be fixed by such patch:

That's one use case.  Another use case is when the candidates are all
related to some issue the user is working on, and therefore leaving
the xref buffer displayed for a long time is what they want.

No.  In my case, I just never bother to dismiss the xref buffer.  The
window showing it is a small one, and sooner or later the xref buffer
gets replaced by *Help* or ChangeLog or one of the other buffers I
display at the bottom of the frame.

This AFAIU corresponds to the situation where the user is not certain
which of the candidates is the one he/she wants.  I don't see how it
fundamentally differs from the original patch, since "M-g M-n" (or
"C-x `", which is what I use) isn't less convenient than 'n' followed
by "C-x o".  It might be more convenient to those who like to dismiss
the xref buffer, but (a) I'm not one of them, and (b) one can dismiss
it without going into it with "C-x 4 C-o".

Do a lot of people really like to dismiss the xref buffer?

In any case, I think questions about this aspect are better answered
by someone who does like to dismiss the buffer, because the issue
simply doesn't bother me enough to give you any useful input.

That's just a minor change in what we have now.  I don't object to
such a change, not even by default, but it isn't what we were
discussing until now.

No, I think xref is actually an improvement in this department,
because it shows the list of candidates instead of letting the user
guess how many are there.

If we don't want to take a guess, I'd suggest leaving the option as it
is, affecting only xref-find-definitions, and extend it to other
commands as user requests arrive.

Hi.  I'm one of the users of Emacs-jp.  Tak introduced us to this
thread and it got me interested, I'm sending this Email.  This
mail thread is huge and I haven't read all of it, so I'm sorry if
I misread the context.

I've created a context menu for ispell (referencing `context-menu-ffap`).
You may find some inspiration from this.

    (defun context-menu-ispell (menu)
      "Ispell at point menu."
      (when t ;; (ffap-guess-file-name-at-point)
        (define-key menu [ispell-separator] menu-bar-separator)
        (define-key menu [ispell-at-mouse]
          '(menu-item "Check spelling of word" ispell-word
                      :help "Check spelling of word under or before the
cursor.")))
      menu)

Regards,
Naoya.

Thanks for the suggestion.  I think such menus should be added to their
respective packages.  context-menu-ispell could be added to ispell.el
(when flyspell is unavailable).

Then dictionary.el could provide own context menu too:

I see.

This does not correspond to my usage and expectations, but, fingers 
crossed, this addition will satisfy the needs of other former users of 
'find-tag' as well.

All right. You still prefer the original patch, then?

Yes, the original patch satisfies my needs, AFAICT.  It would be good
to hear from Juri as well, though.

Thanks.

Sorry, I can't find the original patch.  This bug#50067 collected
so many different things, so it's now hard to find anything.

Oh, I thought there were two patches: the patch above and also
the original patch.  But it the above is the original patch,
then I'd recommend to add more already discussed additions,
so the new option could provide at least these choices:

1. 'jump': Jump to the first location by selecting its window;
2. 'show': Show the first item, but keep focus in the Xref window;
3. 'move': Move point to the first item in the Xref window
   without showing it (maybe this should be the default behavior).

To be able to add later a similar variable for xref-find-references,
the new variable for xref-find-definitions could be named accordingly
with a name that refers to xref-find-definitions, for example,
xref-find-definitions-auto-jump.  Then later xref-find-references-auto-jump.

But maybe still it should delete the region before yanking?
I suggest to try these settings:

  (put 'mouse-yank-primary 'delete-selection 'yank)
  (put 'mouse-yank-at-click 'delete-selection 'yank)
  (put 'menu-bar-select-yank 'delete-selection 'yank)

Then maybe they should be added to delsel.el.

This is not easy to do.  Because there are menu-items
that use the filter :visible, e.g.:

  (defun prog-context-menu (menu)
    (require 'xref)
    (define-key-after menu [prog-separator] menu-bar-separator
      'mark-whole-buffer)
    (define-key-after menu [xref-find-def]
      '(menu-item "Find Definition" xref-find-definitions-at-mouse
                  :visible (save-excursion
                             (mouse-set-point last-input-event)
                             (xref-backend-identifier-at-point
                              (xref-find-backend)))
                  :help "Find definition of identifier")
      'prog-separator)

So it's not known whether the menu-item will be displayed
until the menu is displayed.  So there is no way to remove
a stray separator in the context-menu function that creates
the context menu.

Maybe such items should be rewritten to avoid the filter :visible,
e.g.:

  (defun prog-context-menu (menu)
    (require 'xref)
    (define-key-after menu [prog-separator] menu-bar-separator
      'mark-whole-buffer)
    (when (save-excursion
            (mouse-set-point last-input-event)
            (xref-backend-identifier-at-point
             (xref-find-backend)))
      (define-key-after menu [xref-find-def]
        '(menu-item "Find Definition" xref-find-definitions-at-mouse
                    :help "Find definition of identifier")
        'prog-separator))

Can I ask why do we need the separators in the context menus?  Why not
remove them all, unconditionally?

We can do that. Do you expect to be using more than 1 of these values 
yourself, or is it just for completeness?

Regarding 3 as default, it makes a certain sense, but then you won't be 
able to iterate through all locations with just 'n'. You'd have to press 
'C-o' and then 'n', 'n', 'n'...

I think the "other" variable would be called something with the word 
"xrefs", not "references", and apply to other commands as well, such as 
xref-find-apropos and project-find-regexp.

So the proposed scheme would not quite work. Maybe like this instead?

  - xref-auto-jump-to-first-definition
  - xref-auto-jump-to-first-<xref/item/match/result>. Or just 
xref-auto-jump-to-first.

A good indication that all values are needed is that I still can't decide
which to use, so it would be possible to switch to another value when
one of them does too much or too little.

I agree, it should not be the default.

grep/compilation already supports the value 'jump' by non-nil
'compilation-auto-jump-to-first-error', and the value 'move' when
'compilation-scroll-output' is customized to 'first-error'.

But I think for xref still two separate options are needed
xref-auto-jump-to-first-definition for xref-find-definitions, and
xref-auto-jump-to-first-xref for other more grep-like xref commands.

BTW, I'm testing compilation errors/warnings on xref context menu,
and it reposts this warning:

  prog-mode.el:60:12: Warning: the function `xref-backend-identifier-at-point'
      is not known to be defined.

on this code:

  (defun prog-context-menu (menu)
    (require 'xref)
    (define-key-after menu [prog-separator] menu-bar-separator
      'mark-whole-buffer)
    (when (save-excursion
            (mouse-set-point last-input-event)
            (xref-backend-identifier-at-point
             (xref-find-backend)))
      (define-key-after menu [xref-find-def]
        '(menu-item "Find Definition" xref-find-definitions-at-mouse
                    :help "Find definition of identifier")
        'prog-separator))

Maybe `xref-backend-identifier-at-point' should be autoloaded?

The separators are of great help to provide visual cues for groups
of objects.  All menus on the menu-bar in Emacs use separators.
Anyway, this is implemented now:

I don't know. What are the rules?

There is no risk to call it before xref.el is loaded because 
xref-find-backend itself is autoloaded.

But the lack of autoloading can cause byte-compilation warnings. They 
can be dealt with by other means too, though.

It's now in master: two variables, three methods of behavior for each.

Let me know if you see any problems.

Thanks, one problem is that defcustoms have no '(const nil :tag'
for the default value 'nil'.  I don't know what tag to use,
maybe "No auto-jump".  There were other problems so that it was
easier to just push the fix :)

Thanks! I really skipped on testing the Customize behavior.

Other programs don't show the keys in context menus.
The Human Interface Guidelines say:

  Show keyboard shortcuts in menu bar menus, not contextual menus.
  Contextual menus are already shortcuts to task-specific commands;
  it's redundant to display keyboard shortcuts too.

This patch hides all keys from the context menus:

I'm not sure I agree with those guidelines -- displaying the key
bindings increases the discoverability of those key bindings.  (Not
using the mouse is more productive in the long term for most people.)

+1.

Provided, that is, that the (context) menu-item
is bound to exactly the same command as the key.
But if the key does something different from what
the item does (e.g. dependent on the context),
then omitting the key name can make sense.

Unconditionally? why??  Emacs always shows the keyboard bindings in
its menus, so why should we care what other apps do?  And why force
this on everyone?

For example, how to explain to the users why a keybinding
is displayed for "Undo", but not for "Redo".

Another question is why currently `C-x u' is displayed
instead of the shorter `C-/' for "Undo".

So maybe simpler just to disable keys only for "Undo"
with ‘:keys ""’.  Or the other way around: to manually
add some suggested keybinding to "Redo".

The patch disables the keys conditionally by adding a new
text property to the menu title.

I meant user's ability to request the display of key bindings in the
menu.  I hope you don't expect users to change text properties on menu
titles as the means to have that control.  There should be an option,
and frankly I don't understand why these menus should behave
differently from any other menu in Emacs that shows commands.

When & why does that need to be explained?
Is there a missing binding, perhaps?

That's an orthogonal problem, which is not
specific to context menus, right?  That's
a general, longstanding problem, IIUC.

Is there a reason why one has and the other
doesn't have a binding?  Does it matter?

How is this related to the general question
of whether _context menu_ items should be
able to have keys listed?  Doesn't all that
you wrote apply to menus generally?

I think it would be better to rebind "Undo" from 'undo'
to 'undo-only'.  Since 'undo-only' has no keybinding,
it will not be displayed in the menu.

Currently the option context-menu-global of context-menu-functions
doesn't take into account the variable menu-bar-final-items
to properly order the menu items.  This patch makes it possible
to order the items of global-map instead of menu-bar-current-active-maps
used in menu-bar-keymap by default:

Actually, here is a better patch that will also allow sorting items on
context-menu-local as well.  The same KEYMAP arg of menu-bar-keymap
could be used also in mouse-menu-bar-map to sort items of [C-down-mouse-3]
in the right order (they were unsorted for a long time):

Only part of the patch that fixes the new feature was pushed to emacs-28.
But the following part that fixes the old function could pushed to master later:

After clicking the right mouse button e.g. on the mode-line's minor-modes,
typing S-F10 on a misspelled word pops up the context menu over the mode-line
instead of the position over the misspelled word.  Because it tries to find
the last event that is a mouse event.  In case of keyboard-based 'context-menu-open'
that let-binds 'inhibit-mouse-event-check' to t, this is not needed:

Why check this condition inside the loops, rather than avoid entering
the loops when the condition is right, in the first place?

And please add comments there explaining the meaning of the
inhibit_mouse_event_check test.

Thanks.

I thought that checking the condition inside the loops
would be less risky for the emacs-28 release branch.

This patch also adds comments, and removes one condition
that is not unnecessary when event with parameters
is not searched when inhibit_mouse_event_check is non-nil:
