Package: emacs
Version: 24.0.93
Severity: wishlist
emacs -Q
M-x info-display-manual RET gnus RET
M-x info-display-manual RET emacs RET
Now my Gnus manual is gone, replaced by the Emacs manual.
I expected it to use a new buffer for the Emacs manual.

Maybe it would be good to append manual names to buffer names
as suffixes like "*info*<gnu>" and "*info*<emacs>" to make
unique and recognizable buffer names?
But since currently uniqueness is provided by adding a number
like "*info*<2>", the following patch will work with the
current naming convention:

It doesn't create new buffers, only finds existing ones. (Did the doc
string suggest otherwise?)
IOW, do it like this:
M-x info-display-manual RET gnus RET
M-x rename-buffer *info*<1> RET
M-x info-display-manual RET emacs RET
M-x rename-buffer *info*<2> RET
(The second rename is not necessary, but it clears the way for yet
another info-display-manual.)
Now you can use info-display-manual, and it will switch to the right
buffer automatically.
I wrote that command because I always have several dozens of Info
manuals open in my Emacs session, and I want to be able to switch
between them without any hassle.

Yes, I can do that. But I think it would be more useful to me if it
worked the way Juri suggested:
Maybe it would be good to append manual names to buffer names as
suffixes like "*info*<gnu>" and "*info*<emacs>" to make unique and
recognizable buffer names?
Maybe require a prefix arg, or have an option, to get that behaviour if
you don't like it.
Anyway, just a feature request, not a bug report.

PS maybe there should be an `info-rename' command that renames an info
buffer to include the name of the displayed manual. Presumably it was
the fact that you had *info*<1>, *info*<2> etc rather than *info*<emacs>
that led you to write info-display-manual in the first place.

Juri's patch for generating *info*<N> automatically is OK with me.

Also because typing "emacs" or "make" is shorter than "*info*<emacs>"
etc., and completion doesn't help much when all the candidates begin
with the same substring.

Huh? Prefix completion for things that share a common prefix just abstracts
away that prefix (by completing to it), so you do not have to type it. The
difference would be that completion would help with the *non*-prefix part.
(I do not have a particular opinion about the rest of what was discussed. Just
pointing out that it is not the case that completion doesn't help much when all
candidates share a common prefix.)

But completion is smart now! :)
C-x b <emTAB
will happily complete to *info*<emacs>

Or maybe `rename-uniquely' should get some (optional) smart behaviour to
use more meaningful names. Names of manuals in info, names of recipient
of current mail message, etc.

But for that, I need to _think_ first. When I go to another manual, I
don't want to think about how to set up the completion thingy.

Then functions like `occur-rename-buffer' could be replaced with a simple
buffer-local naming function (named e.g. `rename-buffer-name-function')
with the behaviour similar to `compilation-buffer-name-function'.
This will help to replace such customizations as:
(add-hook 'occur-hook (lambda () (occur-rename-buffer t)))
(setq compilation-buffer-name-function
(lambda (mode-name)
(generate-new-buffer-name
(concat "*" (downcase mode-name) "*"))))
with just:
(add-hook 'occur-hook 'rename-uniquely)
(add-hook 'compilation-mode-hook 'rename-uniquely)

You mean improve uniquify to handle these cases as well?
Agreed, that would be good,

If we want info-display-manual to do that, we'd need to make sure that
either you can't move up to `dir' and select some other manual in those
info buffers, or otherwise catch this case and dynamically rename the
buffer (e.g. with uniquify).

Me too; added to trunk. The other suggestions discussed in this thread
don't seem particularly necessary to me.
