Subject: 30.0.50; Consider changing info buffer names to info<(org)> rather
 than info<3>
Date: Wed, 13 Sep 2023 12:09:48 +0800

Dear Emacs Developers,

I would like to ask for a small usability improvement to Emacs. Could we
name info buffers as "info<(manual)>" (or, maybe, just
"info<org.info>"), not as "info<3>"? I do not always remember in which
order I open info manuals, and having a file name in the buffer name
should be nice an easily readable.

So far I worked around this by adding:
#+begin_src
(advice-add 'info-display-manual :after
            (lambda (x)
              (rename-buffer (seq-concatenate 'string "info<" (file-name-nondirectory Info-current-file) ">"))))
#+end_src

But advices are generally a hack (albeit very useful), so I thought that
someone might like this feature to be "official".

Thanks a lot!

Did you try using "C-h R"?  It will find the existing Info buffer
without your need to remember any numbers.  Just type

  C-h R org RET

I have dozens of Info manuals in my Emacs sessions, and I always use
"C-h R" to get to those whose numbers I don't remember (which is all
but the 2 Emacs manuals).

But it's not the same thing, is it?
If I open some manual recently and then forget its name, how do I switch
back _to that manual which I have been reading in the past hour but
which name I do not remember_?

At the moment I have installed an advice:

#+begin_src
(advice-add 'info-display-manual :after
            (lambda (x)
              (rename-buffer (seq-concatenate 'string "info<" (file-name-nondirectory Info-current-file) ">"))))
#+end_src

I also have a hack to show buffer names in window titles, and seeing
there info<org> is nicer than info<3>.
(But that snippet is a little suboptimal, so I am a little hesitant to
show it.)

#+begin_src elisp
(defvar-local lockywolf/org-buffer-memoized-title nil)
(defun lockywolf/generate-frame-title ()
  "Generated frame title from all buffers."
  (interactive)
  (let* ((retval "")

                 (walk-window-tree
                  (lambda (x) (setf nwin (+ 1 nwin))))
                 nwin))
         (maxlen (if (= nwin 1) 999 11)))
    ;; (message "lwf:debug:nwin=%s" nwin)
    (walk-window-tree
     (lambda (x)
       ;; (message "mode=%s" major-mode)
       (defun truncate-title (title)
         (seq-subseq
          title
          0
          (min maxlen (seq-length title))))
       (setf retval

It's not?  I think it is the same.  You wanted a simply way of getting
back to a manual that you were reading earlier in the session, which
you still have in some Info buffer, no?  That's what "C-h R" does: it
first looks in the Info buffers already present in the session, and,
if not found, then looks for the manual installed on the system.  In
your case, the first step will succeed.

That's what "C-h R" does.  Did you try it?  If you did, how did it not
"switch back _to that manual which I have been reading in the past
hour"?  For me, it switches back to that manual and to the same place
where I was before.  What am I missing?

If you want to show the name of the Info file on the title bar, you
can modify frame-title-format to use Info-current-file in Info
buffers.

No, it does not do that. C-h R just prompts for a "Manual name: " in the
minibuffer, and if I press TAB, shows all the names for all the
installed manuals in the system.

It does switch to the previously open buffer, if I happen to remember
the name of the manual. But if I do not remember whether I was reading
epa's manual, or pgg's manual (similar features!), I have to go through
them by trial and error.

My hackish script is doing that, but I don't want to cater for each mode
possible. Whey wouldn't a mode name it's buffers informatively?

You are supposed to type "org" and press RET when it prompts.  Because
you know you want to go to the Org manual, right?

Then I don't understand something.  Your original request was to name
the buffer "*info*<org>", so that you could type

  C-x b *info*<org> RET

to return to it, right?  But if you don't remember the name of the
manual, how would you know to type the "<org>" part in the above?  And
if you do remember the name of the manual, then how does

  C-h R org RET

require more from your memory than

  C-x b *info*<org> RET

?  What am I missing here?

Speaking for myself: "C-x b PATTERN TAB" is kind of ingrained in my
muscle memory to switch back to all sorts of buffers I know are open.
So my brain turns "Switch back to that Info buffer for the FOO manual"
into "C-x b info TAB", then I stare blankly at the "*info<N>*"
candidates for a couple of seconds, and pick one at random.

Point taken re. C-h R (which even limits completion to opened manuals
with C-u, neat), though switching buffers with C-x b is such a generic
action that I perform dozens of times an hour without thinking twice,
that I suspect stopping myself from C-x b'ing just for Info buffers is
going to be hard.

Not an urgent issue by any means; just one of the things I plan on
digging into someday.  Adding an option to control that call to `info'
at the end of `info-display-manual' doesn't seem too hard; just haven't
found the time yet (and maybe eventually I'll end up sticking a call to
rename-buffer in Info-mode-hook and calling it a day instead).

No, that is the point, I _do not_ know which manual I am going to.
I am typing C-x b info TAB to see all open info buffers.
And I would like to see: info<org> info<epa> info<mu4e> rather than
info<1> info<2> info<3>.

With TAB-completion. (Or, if someone uses a narrowing framework, like
ivy or helm, it would get by even without TAB.)

Exactly!

C-u C-h R ??? I didn't know about this behaviour of the prefix argument!
It does make things simpler, although really, I think that just adding a
call to (rename-buffer) at the end of 'info-display-manual would not be
that bad.

It isn't, rest assured: I walked that way myself.
