bug#43308: 28.0.50; Improvements to Edit->Search menu

[Ihor Radchenko]

Following up with "Changes for emacs 28" discussion about improving menu
[1]

Source: http://ergoemacs.org/emacs/modernization_menu.html

The following menus seems to be more confusing than helpful:
- Edit->Search menu->String Forward
- Edit->Search menu->String Backwards
- Edit->Search menu->Regexp Forward
- Edit->Search menu->Regexp Backwards
- Edit->Search menu->Repeat Forward
- Edit->Search menu->Repeat Backwards

In most of other applications, the search functionality is squeezed into
single search dialogue, providing searching forward, backwards, and
repeating search together (via next/prev buttons).
Current Emacs menu forces the user to click Edit->Search menu->...
multiple times to repeat the search. That is not a pleasant experience.

Also, the functionality of the above menu items seems to be strictly
inferior in comparison with isearch items from Edit->Search->Incremental
search sub-menu. The only apparent advantage is that user would not need
to know that moving to next/prev match is C-s/C-r.

The article suggests to remove the above Search menu items completely
and replace them by incremental search versions.

I would also add that we can show transient next match/previous match
toolbar icons to assist users, unfamiliar with key bindings. Though need
to make sure that these new toolbar icons can be easily associated with
the search process. For example, we may show additional toolbar at the
bottom (above the mini-buffer isearch prompt) with only these two new
toolbar icons (maybe also "exit search" icon).

Also, the article suggests to rename "Forward/Backward String..." into
"Search Forward/Backwards...", which sounds reasonable since
non-programmer users may be confused by the meaning of word "String".

Finally, find "Search tagged files..." and the following "Repeat" menu
confusing. What does "tagged files" mean? I tried to click it, got a
prompt about regex, then prompt about tag table (what is it?). Finally,
I got error "File ~/TAGS does not exist". This made me recall vague
memory about Emacs manual talking about some kind of completion feature
for large code projects - something I never used.

The above is my actual first impression. The menu seems useless for me,
though may have a value for programmers. However, I have two
suggestions:

1. Menu items do not show the key binding (is in Incremental search
   menu). I think that showing bindings is generally a great idea for
   discoverability

2. There is currently no way to understand what some unfamiliar menus do
   except blindly trying. As I explained about, it does not always help.
   Probably, Emacs could show some kind of tooltip on top of menu items,
   explaining what it does in more details. Also, it would be cool to be
   able to move to Manual page talking about topic relevant to the menu
   item (on right click?).

Best,
Ihor

I disagree.  Many applications have only the non-incremental search
commands, so removing them will leave the user who are used to those
with the incremental variant, which might be confusing for people who
have no experience with comparable commands.

If you are suggesting a "repeat last search" menu item, it could be a
useful idea.  But removing those items because we don't have a simple
repeat item is a step in the wrong direction, IMO.

> Also, the functionality of the above menu items seems to be strictly

See above: it is there for those who are not familiar enough with the
incremental variants.

Please don't forget that the menu bar targets mainly newcomers, so
judging it from the POV of a veteran Emacs user might yield incorrect
conclusions.

Please show the code.  Please also keep in mind that changes on the
tool bar require redrawing of the tool bar, which could cause
unpleasant flickering.  We need to consider this potential downside.

The "Search" part is in the parent menu item, so repeating it would be
a waste of space, which is at premium here.

If people agree that removing "String" will help, maybe we could do
that.  But please note that "String" contrasts with "Regexp" in the
next items; if we remove it, won't that be less clear?

> Finally, find "Search tagged files..." and the following "Repeat" menu

Feel free to suggest a better name for the item and/or a better help
string.

Did you try "C-h k" before selecting that?  This would display the
documentation of that command.  It's a canonical way of learning about
menu items that don't explain themselves enough at first reading.  (Of
course if we can make them more self-explanatory, it's better.)

If there's no key binding shown in the menu, it means the command
invoked by the menu item doesn't have a key.  When there's a key
binding, the machinery that displays the menu adds them automatically.

See above: "C-h k" is the way to understand that.

Thanks.

I think this is less of a concern these days.

The applications you talk about also have search dialog boxes, which
make the non-incremental search actually useful.

Firefox also has incremental search by default, which many (most?) of
our users will already be familiar with.

This is a separate discussion, I think, but on graphical displays I
would ideally like to see a user interface like the one in C-f Firefox.
It shows clickable buttons for next/previous match, toggles for "Match
Case", "Whole Words" and how many matches there are.

Alternatively, see my suggestion about doing it like Firefox above.
IMHO, the tool bar is not a place where you would expect to find this.

I think removing it is fine.  Already saying "Regexp" makes it clear
that this is the odd one out.

(IIRC, this is what you find in other software: the regexp case is the
one with a special mention, otherwise it's just called "Search".)

We could perhaps move it to a menu related to tags functionality?  Just
an idea.

Right.  The problem here is that these commands are specifically
designed to be run from the menu.  Is there any way to work around that?

Maybe this should be clarified more in the doc string of C-h k.  I never
realized you can use "C-h k" to find out more about menu options, but I
suppose it makes sense now that you mention it.

Perhaps we could add a special command under the "Help" menu that says
"Help for menu" that when clicked runs C-h k with a special message in
the mini-buffer "Click the menu command you want help for"?

In what way is this less of a concern?

That's true in some cases, but not in all of them.  And the dialog is
not really relevant here: the issue I raise is with the concept of
incremental searching being unfamiliar.

> Firefox also has incremental search by default, which many (most?) of
> our users will already be familiar with.

Some applications added incremental search, but many don't have it,
and probably never will.  Simple editors are in that class.

Improving the (non-existing) search dialog is a separate discussion.
If you want to work on such a dialog, please do.  but that is not what
we are talking here.  The proposal on the table is to remove
non-incremental search commands from the Search menu.  let's stay
focused on that issue, okay?

No, I think this is fundamentally a search command.  TAGS is just an
aid.

What kind of workaround do you have in mind?

There's something new to learn about Emacs every day ;-)

I don't mind, if this will really help this to be more discoverable.
(Of course Xah Lee thinks that our Help menu is too large as it is...)

Users are more familiar with incremental search, for example from
Firefox.  I checked, and Chromium also has it, and IIRC so does Safari.
Assuming that our users have used any of those web browsers, they will
already have had exposure to incremental search.

In any case, even if they haven't, the feature will quickly be learned
once you start using it.

I'm not sure.  Either we add specific workarounds for them in the menu
code, or we make sure the original commands are adapted to suit this
task.  But it would be good to show the keybindings, since one of the
main purposes of the menu is to make functionality discoverable.

The example apps you show are not editors.

The menus are supposed to help first-time users, with little or no
experience in using Emacs.  Once they start using the incremental
search, the menus are probably not for them anymore.

The problem is that the key sequence invokes a different command.

About the only solution I see is to mention the keyboard equivalent in
the doc string of the command invoked by the menu.

And, btw, their incremental search works subtly differently: once you
click the Next or Previous button, typing characters doesn't
necessarily modify the search string, you need to click in the search
field for that.

So even if the user has some experience with these browsers, they
won't necessarily feel at home with Emacs's Isearch.

I think there is no need in such dialog because when Isearch is active,
there is the isearch-specific tool-bar and Isearch submenu in the menu bar.

There is a menu item in the Isearch submenu named "Nonincremental search".

But it you really don't want to remove nonincremental menu items from
the Edit menu then they could be swapped with incremental menu items,
i.e. to promote incremental menu items higher, and demote nonincremental
menu items deeper to the submenu where currently more often used
incremental menu items are located.

That'd be the opposite of what the menu should be doing, which is
putting the easier and more familiar commands closer to the top level.

TUTORIAL teaches about incremental commands:

  * SEARCHING
  -----------

  The Emacs search command is "incremental".  This means that the
  search happens while you type in the string to search for.

  The command to initiate a search is C-s for forward search, and C-r
  for reverse search.  BUT WAIT!  Don't try them now.

  When you type C-s you'll notice that the string "I-search" appears as
  a prompt in the echo area.  This tells you that Emacs is in what is
  called an incremental search waiting for you to type the thing that
  you want to search for.  <Return> terminates a search.

  Did you see what happened?  Emacs, in an incremental search, tries to
  go to the occurrence of the string that you've typed out so far.  To
  go to the next occurrence of "cursor" just type C-s again.  If no such
  occurrence exists, Emacs beeps and tells you the search is currently
  "failing".  C-g would also terminate the search.

  If you are in the middle of an incremental search and type <DEL>, the
...

so this is what newbies need to know and use from the menu.

bug#43308: 28.0.50; Improvements to Edit->Search menu

[Ihor Radchenko]

It seems that the opinions are a bit split here, so I will try to
summarise the current state of the discussion in this message and refine
my suggestions from original bug report.

First of all, let me clarify on the purpose of the menu/toolbar as I
understand it. I tried to make sure that it is consistent with opinions
of others, but feel free to reply if you disagree.

Target users:

1. Menu is designed for users unfamiliar with Emacs concepts
2. Moreover, we do not expect those users to read Emacs manual or even
   tutorial
3. All the users are expected to know functionality, which is common
   among modern editor apps
4. Menu does not try to show all possible functionality of Emacs, just
   the most important (otherwise, people will be lost in too many menu
   items)

The aims of the menu:

1. Show people Emacs equivalents text editing functions they would
   expect to use from other editors
2. Provide an indication how to switch to Emacs-specific commands (by
   indicating key bindings and command help)
3. Provide the most important Emacs-specific commands, which can be
   useful even though they have no equivalent in other editors

Now, let me go through my original proposal and put in into the context
of the above principles, while taking into account the comments on this
bug report.

----------
1. Replacing non-interactive search by interactive search
----------

There seems to be controversy on this part of the proposal:

My reply:

The above comment that incremental search may be unfamiliar is a valid
concern. However, non-interactive search is not commonly used in Emacs
by people who get some minimal experience (correct me if I am wrong). We
are promoting the command that may be relatively easy to used for the
user, but it does not help the user to learn the more common and
powerful Emacs equivalent (which is isearch).

As Stefan Kangas mentioned, we can expect that users are somehow
familiar with incremental search concept from browsers. People
unfamiliar with browsers are very uncommon case - if we start to
consider all such possibilities, menu will grow into duplicate of custom
interface (in terms to overly too many features).

It was also mentioned that isearch behaves differently from what users
might expect. However, the non-interactive search also behaves very
differently - users cannot go to next/previous match easily. They have
to go to menu->edit->search->repeat forward/backwards. On the contrary,
isearch does provide forward/backward search buttons at least (though
they are located far from the entered search string - in the toolbar). I
would argue that isearch does a better (not ideal though) job creating
familiar interface.

Therefore, I would favour isearch over the non-interactive version.

2. Showing next match/previous match toolbar icons to assist users, unfamiliar with key bindings
-----------

When writing this suggestion, I did not know that these icons are
already shown on the toolbar. In fact, toolbar during isearch does even
better job - it provides next/prev match _and_ more useful commands from
isearch-mode-map. Moreover, it even gives a button to show help buffer
about isearch.

There is no such toolbar functionality for non-interactive search
though.

My reply:

I think I need to clarify that by showing toolbar buttons during search,
I proposed something similar to C-f in Firefox - buttons for prev/next
search are shown right above/below the input box for search string.

In the case of Emacs, that would mean showing prev/next match toolbar
buttons right above the minibuffer.

Moreover, as I mentioned earlier, there is already toolbar functionality
for isearch. If the toolbar was moved to the bottom of the frame during
isearch, it would be sufficient to achieve what I had in mind. Current
top position is very easy to miss (I did miss it even though I was
looking into isearch menu item specifically).

I believe that the same functionality can be implemented for
non-interactive search - we can reuse the same toolbar as in isearch.
Moreover, having prev/next match buttons will effectively provide the
following separate menu items in a single search command (or maybe in
two commands for forward/backward search):
- Edit->Search menu->String Forward
- Edit->Search menu->String Backwards
- Edit->Search menu->Regexp Forward
- Edit->Search menu->Regexp Backwards
- Edit->Search menu->Repeat Forward
- Edit->Search menu->Repeat Backwards

Same with isearch, I believe that the toolbar position would better be
right above the minibuffer.

On the flickering issue: Does it exist with the current toolbar for
isearch? If there no bug reports on it, it is probably just hypothetical
and we should not care about it.

My reply:

No space will be wasted when renaming "Forward/Backward string" to
"Search forward/backward". The char count is the same. But, as I said we
add an extra benefit of not using word that is potentially confusing for
non-programmers.

My reply:

I cannot suggest a better name since I have no idea how the TAGS
functionality works. I just wanted to point out that it was confusing
for me. I never had to deal with big multi-file projects where TAGS
search is needed.

As you said in another message:

We cannot expect the user to know about "C-h k".

My concrete suggestion is using the tooltip to hint the user how to get
more information about the command. The tooltip is already showing a
short (yet longer than menu item name) command description. I suggest to
add something like "Use mouse-3 (middle click) to get more information"
and bind mouse-3 to show help buffer on the command.

Thanks, but this method of summarizing the discussion by repeating
most of it is not useful.  It makes the "summary" very long and
tedious to read.  A summary should just show the main arguments
without citing the OPs.  People who want more details can always read
the archives.

I don't think there's disagreement about the principles.  When you
posted them the last time, I don't think anyone objected.  So I see no
need to reiterate them.

> Therefore, I would favour isearch over the non-interactive version.

And I'm against it.  Where does that leave us?

More generally, how is it useful to keep repeating your opinions which
are clearly not agreed to by at least some?  A useful step would be to
propose some compromise, or modify your proposal in some other way
that might take away some of the objections.

And what are we actually arguing about here?  Both non-incremental and
incremental search commands are already in the menus.  The proposal to
_remove_ the non-incremental commands is based on some (unproven)
assumptions, so it runs a risk of adversely affecting users which
those assumptions failed to consider.  Why take that risk?  I've seen
no answer to that question.  I agree that incremental search is more
powerful, but your principles don't (and shouldn't, IMO) state that we
want to show there only the most powerful commands.  So having both is
having the best of all worlds, and I see no reason to change that.

This can be fixed by providing tool-bar buttons for repeated search,
or reusing the buttons we already have for incremental search.  It's a
separate issue that is easy to fix, and no one objected to providing
this.  So it doesn't have to be an argument regarding the main issue
here.

Let's add it, then.  This would be a good improvement, I think.

Firefox is just one application.  Other applications show the
next/prev match just below the tool bar, above the text area.  I see
no reason why we couldn't do the latter.

Moving the tool bar downwards is a non-starter in the context of this
discussion.  It means a very serious redesign of the Emacs display,
and will confuse many users.  It makes little sense to make such
significant changes, for a minor issue like this one, because we
insist on following the example of Firefox, instead of reusing what we
already have.

We will not do this, not because of the search commands.

Feel free to start a more general discussion of moving the tool bar to
below the windows, but let's not complicate this particular discussion
by such grandiose and radical ideas.

> We cannot expect the user to know about "C-h k".

But we can expect them to know about the corresponding item in the
Help menu.

Improving tooltips is of course welcome.  Please suggest text you
think will be more helpful.

Thanks.

bug#43308: 28.0.50; Improvements to Edit->Search menu

[Ihor Radchenko]

It seems that the opinions are a bit split here, so I am try to
summarise the current state of the discussion in this message and refine
my suggestions from original bug report.

First of all, let me clarify on the purpose of the menu/toolbar as I
understand it. I tried to make sure that it is consistent with opinions
of others, but feel free to reply if you disagree.

Target users:

1. Menu is designed for users unfamiliar with Emacs concepts
2. Moreover, we do not expect those users to read Emacs manual or even
   tutorial
3. All the users are expected to know functionality, which is common
   among modern editor apps
4. Menu does not try to show all possible functionality of Emacs, just
   the most important (otherwise, people will be lost in too many menu
   items)

The aims of the menu:

1. Show people Emacs equivalents text editing functions they would
   expect to use from other editors
2. Provide an indication how to switch to Emacs-specific commands (by
   indicating key bindings and command help)
3. Provide the most important Emacs-specific commands, which can be
   useful even though they have no equivalent in other editors

Now, let me go through my original proposal and put in into the context
of the above principles, while taking into account the comments on this
bug report.

----------
1. Replacing non-interactive search by interactive search
----------

There seems to be controversy on this part of the proposal:

My reply:

The above comment that incremental search may be unfamiliar is a valid
concern. However, non-interactive search is not commonly used in Emacs
by people who get some minimal experience (correct me if I am wrong). We
are promoting the command that may be relatively easy to used for the
user, but it does not help the user to learn the more common and
powerful Emacs equivalent (which is isearch).

As Stefan Kangas mentioned, we can expect that users are somehow
familiar with incremental search concept from browsers. People
unfamiliar with browsers are very uncommon case - if we start to
consider all such possibilities, menu will grow into duplicate of custom
interface (in terms to overly too many features).

It was also mentioned that isearch behaves differently from what users
might expect. However, the non-interactive search also behaves very
differently - users cannot go to next/previous match easily. They have
to go to menu->edit->search->repeat forward/backwards. On the contrary,
isearch does provide forward/backward search buttons at least (though
they are located far from the entered search string - in the toolbar). I
would argue that isearch does a better (not ideal though) job creating
familiar interface.

Therefore, I would favour isearch over the non-interactive version.

-----------
2. Showing next match/previous match toolbar icons to assist users, unfamiliar with key bindings
-----------

When writing this suggestion, I did not know that these icons are
already shown on the toolbar. In fact, toolbar during isearch does even
better job - it provides next/prev match _and_ more useful commands from
isearch-mode-map. Moreover, it even gives a button to show help buffer
about isearch.

There is no such toolbar functionality for non-interactive search
though.

On the flickering issue: Does it exist with the current toolbar for

bug#43308: 28.0.50; Improvements to Edit->Search menu

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Eli didn't like that idea, but I wonder whether it makes sense to just
move "Incremental Search" up out of "Search"?  Because "Incremental
Search" is probably as popular as non-incremental search.

I.e., have both

Search
Incremental Search

directly under Edit.

I won't object to such a change, but IMO it's important to keep the
above order, i.e. not to put "Incremental Search" first.

OK; now done in Emacs 29.

The "because" is true, but it doesn't motivate such a move.

Leave all search under Search.  Don't add menus needlessly.

(And I have a top-level Search menu on the menu-bar.)

FWIW: Attached are screenshots showing the Search menu
that I use, in menu-bar+.el.

The only thing in the screenshots that isn't vanilla
is submenu Search > Icicles.  The rest is all vanilla.
There are 5 submenus (besides Icicles).

You can see how I deal with forward & backward, with
with incremental & nonincremental, and with repeated
nonincremental (forward & backward).  I think it's
pretty clear for users.

(I used to have nonincremental items at top level,
but moved them to a submenu because their use is
less common now.  Admittedly, if someone uses this a
lot then accessing via submenu is less efficient.)

Why no keybindings are shown for nonincremental menu items?
They still have keybindings, e.g. nonincremental forward search
can be started with 'C-s RET', nonincremental backward search
with 'C-r RET', nonincremental regexp search 'C-M-s RET', etc.

Those are not ordinary key bindings that can be discovered by
where-is-internal (which doesn't know about any temporary use of
overriding(-terminal)-local-map).

I suppose I could add some explicitly, with :keys.
That makes sense.  Unfortunately, none show up
automatically.  It would be good to somehow fix that.
E.g., `C-h f nonincremental-search-forward':

  nonincremental-search-forward is an interactive compiled Lisp function
  in 'menu-bar.el'.

  It is bound to <menu-bar> <edit> <search> <search-forward>.

  (nonincremental-search-forward &optional STRING BACKWARD)

  Read a string and search for it nonincrementally.

I've done that now.

Of course, advertising such keys is a lie whenever
option `search-nonincremental-instead' is nil.

Too bad we can't have :keys be a sexp that is eval'd at
menu display/update time, and have a :keys value of nil
mean not to show any thing for the key bindings.

How about the following patch?

BTW, why "Search Tagged Files..." and "Continue Tags Search" have
no keybindings?

Another problem is that selecting "Continue Tags Search"
signals the error:

emacs -Q
Select "Edit" -> "Search" -> "Continue Tags Search"

  Lisp error: (wrong-type-argument commandp fileloop-continue)

I think "Continue Tags Search" should be disabled when it has no effect.

But the keys this will show don't invoke the same commands, they
invoke slightly different commands, don't they?  I don't think we ever
show keys that invoke a different command, why do this here?

I guess this is a leftover from migration to Xref.

Yes, it should be.

The comment in 'nonincremental-search-forward' says:

  ;; Ideally, this whole command would be equivalent to `C-s RET'.

This seems to imply that currently it's not equivalent.
Then indeed displaying wrong keys would be misleading.

Do you mean these obsolete menu items should be removed since
now there are Xref commands in the "Go To" submenu?

No, the commands do exist, but I think we have a bug there which
causes the error you saw.

It doesn't fix the nonautomatic display of keys, does it?

> BTW, why "Search Tagged Files..." and "Continue Tags Search" have
> no keybindings?

Because they have no keyboard key bindings.  Or was
that your question?  Did `tags-search' ever have a
default keyboard binding?  For `Continue Tags Search'
I think the reason was that when Emacs moved to xref
it dropped the `M-,' key binding for that command
(`tags-loop-continue').  (I wasn't in favor of that.)

I don't see that with emacs -Q, loading menu-bar+.el,
and using that item in the Search menu (which is not
under Edit).  Dunno why.  I see just this error message:
"No operation in progress", which makes sense.

I've done that now, in menu-bar+.el.  I use this, but
perhaps someone can let me know if it's not the right,
or best, condition to use.  (I use condition-case, not
ignore-errors, for compatibility with older Emacs.)

:enable (not (condition-case nil
                 (tags-loop-eval tags-loop-scan)
               (error t)))

The error occurs only when fileloop.el is not yet loaded.

I tried this, but it doesn't enable "Continue Tags Search"
after starting "Search Tagged Files...".  And I don't know
what else could be checked.

I think the xref changes broke the use of the tags code.
You can use `M-x tags-loop-continue'.  I think that
:enable code should work - and it does work for Emacs < 27.

But you're right that it no longer works.  Looks like the
code for the tags-search feature was changed partially,
and stuff was declared obsolete (which shouldn't have been
done, IMO).

* Xref as an alternative is one thing - OK.
* Xref as the new default is another thing - OK, but not my
  preference.
* Xref stealing the same keys is yet another thing - Not OK, IMO.
* But declaring the tags functionality and code to be
  obsolete is KO, IMO.  Overzealous NIH'ism, I expect.

Users should have both tags and xref available, as equals.

Guess I'll have to :enable that menu item unconditionally
for Emacs 27 and later (and leave it conditional for
Emacs before the breakage):

(define-key menu-bar-search-tags-menu [tags-continue]
  '(menu-item "Continue Tags Search/Replace" tags-loop-continue
    :help "Continue last tags search or replace operation"
    :enable (or (> emacs-major-version 26)
                (not (condition-case nil
                         (tags-loop-eval tags-loop-scan)
                       (error t))))))

As usual, because the menu invokes different commands, not those for
which key sequences exist.

Someone else will need to do that, I'm afraid.

Or if you post something here that I can use
to replace the :enable code I showed, I'll be
glad to try that and let you know what I see.

You can see the code via the Git Web interface offered by Savannah's
Emacs page.  I provided a link several times in the past.

If you post something here that I can use to
replace the :enable code I showed, I'll be
glad to try that and let you know what I see.

Sigh...  As mentioned several times before, please go to

  https://git.savannah.gnu.org/cgit/emacs.git

Click on "emacs-27", find my change from a few hours ago, click on its
line, and you will see the diffs.

(Can I convince you to bookmark that page, and use it henceforth when
you want to see some change installed in the repository?)

Good advice, but this reminds me of something that occurred to me some
time ago: Perhaps it would be nice if the script that sends out diff
emails also looked for text in the commit message that says "bug#4242"
and then Cc's 4242@debbugs.gnu.org?

It would be especially useful when doing bug triage on reopened bug
reports, where you could see what the patch applied was without going on
an archaeological expedition into git log, but also generally more
friendly towards bug reporters, who could then see the patch immediately
themselves.

I don't think I want to get patches in my mailbox twice.  There's
emacs-diffs for that purpose.

I thought the bug reporter got a copy of all mail to the
@debbugs.gnu.org address?  Hm.  But...  come to think of it, they don't

Not unless there's some magic on debbugs.  They get the message which
closes a bug, but I don't think they automatically get other messages,
unless they are CC'ed.

That sounds like the direct opposite of what is being saiught here,
doesn't it?

It doesn't help with sending the patch to the bug reporter, but it does
fix the problem of stashing a copy of the patch in the bug tracker (and
not annoying anybody when doing so), though.

Yes, that's the issue I was thinking about (sorry for not being explicit
enough, I counted on my selective quoting to do the work for me).

FWIW this feature (having the BTS record what patches were applied in
the context of a specific report) is a thing other forges do.

I can't speak for the maintainers of projects hosted on these forges,
but I can imagine it being handy: sure, finding all commits referencing
a bug ID is "just one Git command away", but that can mean a couple of
seconds twiddling one's thumbs while the disk spins; having that
information readily displayed in the thread sounds like a timesaver.

It also helps the people who are looking at the web interface -- the
patch that resolves the bug report would be there, which I often find
helpful when looking at problems in other systems.

It could also be an HTTP URL instead of the patch itself, if we wanted 
to avoid duplication.

I'd prefer the patch itself -- systems come and go, and URLs don't last.

I think we're miscommunicating.  I didn't ask
to see your patch (diff).

I said that if you post here code I can use
to replace the :enable code I showed then I'll
be glad to help out by trying it and letting
you know what I see.  If you don't want to do
that, fine.

And thanks for patching, assuming the result
takes care of the problem discussed.  In that
case, when Emacs releases again (27.2?), with
the patch applied, Emacs will no longer present
the reported regression - the same :enable
will work for all Emacs releases (except 27.1).

In that case, the :enable condition will become:

(or (version= "27.1" emacs-version) ; bug #43569
    (not (condition-case nil
             (tags-loop-eval tags-loop-scan)
           (error t))))

so that the menu item is still enabled
unconditionally for the (presumably still)
broken 27.1.

The patch shows the code, doesn't it?  So why do you insist on seeing
the code and not the change?

I didn't insist on anything.  If you want me to help
by trying some alternative :enable code I'm willing
to do that, if you show that :enable code.

If not, that's OK by me.  I'll go with this as a guess:

(or (version= "27.1" emacs-version) ; bug #43569
    (not (condition-case nil
             (tags-loop-eval tags-loop-scan)

That's not what I've done.

[Drew Adams]

> That's not what I've done.

OK, I've looked at your patch; thx.  And I've updated
my code.  For Emacs < 27, I've found that there's no
good condition for :enable.  I was mistaken thinking
that (tags-loop-eval tags-loop-scan) could be used.
___

FWIW:

I call the menu item for [tags-repl-continue]
"Continue Search/Replace", with :help "Continue last
tags search or replace operation".

It's incorrect to say that it continues the last tags
replace operation.  It continues the last tags search
or replace operation.  If the last tags operation was 
`tags-search' and not `tags-query-replace', then it
continues the last search, not the last replace.

That is factually correct, but I think the current menus are less
confusing to newbies than your proposal.

I won't argue about it, but I think that as soon as a
user tries tags-searching and then tries to go back to
continue a tags query-replace, s?he will be mightily
surprised.  Likewise, trying to go back to continue a
tags search after having last done a tags query-replace.

That's exactly how I discovered this.

If we had separate "continue" commands, at least from
the menus, then this wouldn't be a gotcha.

I do agree that simply having a menu item or help echo
that refers to continuing the last search or replace is
hardly the best remedy.  It would be good, I think, for
some remedy to be applied.

Like I said: factually correct, but there's no reason for the user to
do something like that, except by accident.
