Subject: 24.0.50; (emacs) `Menu Mouse Clicks' conflicts with code obsolescence
Date: Mon, 22 Nov 2010 08:51:11 -0800

The footnote on this manual page tells you how to put the mouse-3 menu
on mouse-3 instead of on C-mouse-3 (the default).  It tells you to bind
`mouse-popup-menubar-stuff'.

But in mouse.el, that function (as well as the other mouse-3 menu
functions) has been declared obsolete since 23.1.
 
There is no comment in the code indicating what now replaces these
functions - what to use instead.  And I find nothing in NEWS or NEWS.23
(or NEWS.22) about "mouse-3" or "popup".  Grepping the Lisp sources
didn't help either.

How are users supposed to know how to code this, now that these
functions are obsolete?  What is the right way to do it now?  Where in
the Lisp code is C-mouse-3 doted with menus (e.g. the major-mode
menubar menu)?

Good question.  I see from bzr that Juanma marked the function as
obsolete.  Do you know what this is all about?

No, I didn't, I just added the "23.1" WHEN argument.

You use `d' to check the change, and if it is not the one you're
interested in, C-u C-x v g and pass the revno just before that change
(I mean, revno - 1), so you get a new vc-annotate log. Repeat until
`d' in the line you're intested shows the change you're after.

Thanks; very useful.

Perhaps there should be a command in the Annotate buffer to do this?  I
mean, to re-run annotate on (1- commit-under-point)?

Do you mean `vc-annotate-revision-previous-to-line', bound to a
in the annotate buffer, by any chance?

Yes, thanks.

I knew it wasn't a good idea to bet against it.

C-h f mouse-major-mode-menu RET tells me

   This function is obsolete since 23.1;
   use `mouse-menu-major-mode-map' instead.

So for me it does say what replaces it.

> Good question.  I see from bzr that Juanma marked the function as

It's mostly about what C-h k returns:

Before my patch "C-h k mouse-3" returns "mouse-3 runs mouse-major-mode-menu"
whereas after my patch it pops up the menu, lets you choose an entry from
it and then gives you the name and docstring of the function
corresponding to the entry you selected.

Still true, in the latest Windows build:

In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
 of 2011-07-11 on 3249CTO
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (4.5) --no-opt --cflags
-Ic:/build/include'

Likewise, this is still true:

It does not tell you "how to put the mouse-3 menu on mouse-3 instead of on
C-mouse-3".  It is not specific wrt doing what that now-obsolete variable did.
Likewise, wrt doing what the other mouse-3 menu functions (also made obsolete)
did.

Several things have been declared obsolete, and there is not even a comment in
the code indicating what to do in their stead.  And nothing in NEWS.  And the
doc still refers to what is obsolete - "since 23.1", as you point out.

And, as you point out, the manual says:

   (1) Some systems use `Mouse-3' for a mode-specific menu.  We took a
survey of users, and found they preferred to keep `Mouse-3' for
selecting and killing regions.  Hence the decision to use `C-Mouse-3'
for this menu.  To use `Mouse-3' instead, do `(global-set-key [mouse-3]
'mouse-popup-menubar-stuff)'.

I assume that we're not asking people to bind mouse-3 to
(mouse-menu-major-mode-map)?

Because I tried that, and it didn't give me the same menu that's
currently on `C-mouse-3'.  :-)

Oh, right it's not what I thought.  Yes, it's a bit inconvenient to move
the mapping from C-mouse-3 to mouse-3 because you really want to put
onto mouse-3 the menu-item that's on C-mouse-3, but

(global-set-key [down-mouse-3] (key-binding [C-down-mouse-3]))

will only give you the keymap returned by mouse-menu-major-mode-map
rather than the menu-item itself.  You'd like to be able to do:

  (global-set-key [down-mouse-3] [C-down-mouse-3])

But that doesn't work because such remapping don't work right for events
with parameters such as mouse clicks.  I guess you can do:

  (global-set-key [down-mouse-3] (cdr (assq 'C-down-mouse-3 global-map)))

but it's ugly.  Maybe we need a way to ask `key-binding' to return
menu-items rather than the binding specified in them.  But key-binding
already takes many parameters..maybe we could abuse the `no-remap' arg
for that?

Like the normal command loop, `key-binding' will remap the command
resulting from looking up KEY by looking up the command in the
current keymaps.  However, if the optional third argument NO-REMAP
is non-nil, `key-binding' returns the unmapped command.
---

Using `no-remap' for that sounds like a reasonable thing to do.

This text is no longer there in the manual, presumably it has been
updated in the 12 years since this was reported.  I'm therefore closing
this bug report.

OK, that text is no longer there.

But "how to put the mouse-3 menu on mouse-3 instead
of on C-mouse-3"?  Is that documented somewhere?
Is it still possible?  If it was documented before,
and it's still possible, shouldn't it be documented
now (somewhere)?

In Emacs 28.1, this should be (from NEWS):

** New minor mode 'context-menu-mode' for context menus popped by 'mouse-3'.
When this mode is enabled, clicking 'down-mouse-3' anywhere in the buffer
pops up a menu whose contents depends on surrounding context near the
mouse click.  You can change the order of the default sub-menus in the
context menu by customizing the user option 'context-menu-functions'.
You can also invoke the context menu by pressing 'S-<F10>' or,
on macOS, by clicking 'C-down-mouse-1'.
