bug#1761: 23.0.60; Can't reach info nodes that aren't in TOC

[David Abrahams]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This is arguably a feature request, but it seems so glaring that you
might consider it a bug.  If I'm in an xterm and type `info dbus' I get
a nice info session about emacs/dbus integration.  But there doesn't
seem to be any way to visit the same page from within emacs using
info-mode other than `M-: (info "dbus")'.  This seems needlessly
inconvenient.  `C-u M-x info <RET> dbus <RET>' ought to get me to the
same node if there's no info file named "dbus" in the current working
directory.  Also, there should be some syntax to disambiguate:
`C-u M-x info <RET> :dbus <RET>' maybe

Thanks and regards,
Dave

When you are in Info mode of Emacs, you can type "g (dbus)". This will
show you the DBus info page, if there is a corresponding file in one of
the directories of `Info-default-directory-list'.

I also wanted something like that, so I wrote this as a start:

(defun srb-info ()
  "Enter Info at the Info file the user chooses, tabbing for completion.
If you type parentheses around the Info file name and then type a
node name, e.g. `(emacs)Buffers', then Info enters the file at
that node (completion for nodes below the file level is not
provided)."
  (interactive)
  (require 'info)
  (let (files idx info-files info-file)
    (dolist (d Info-default-directory-list files)
      (when (file-readable-p d)
	(setq files (cons (directory-files d) files))))
    (setq files (append (car files) (cadr files)))
    (dolist (f files)
      (setq idx (string-match "\\." f))
      (setq info-files (cons (substring f 0 idx) info-files)))
    (dolist (f info-files)
      (when (string-match "-[1-9][0-9]?$" f)
	(setq info-files (delete f info-files))))
    (setq info-file (completing-read "Info file name: " info-files))
    (unless (string-match "^\([^ ]+\)" info-file)
      (setq info-file (concat "(" info-file ")")))
    (Info-goto-node info-file)))

But "g (dbus)" already can complete on a file name when point is located
after the opening parenthesis.

From within Info, yes, but the purpose of the function I wrote (and what
I understood the OP to be requesting) is to open any info file with a
single command invocation when you're not in Info mode.

That's exactly right.  It's a very odd that I can type "info foo" at the
shell command-line and get what I want, but Emacs makes me look at the
entire info index before I can tell it that I'm really interested in a
section that isn't in the index.

Now you can use

M-x info-display-manual RET dbus RET

You can also use g (dbus) in any info buffer.

"g (dbus)" loads the dbus manual into the current info buffer, which
means you lose the previous manual that was loaded there.
info-display-manual doesn't have that problem.

l will go back there, though.

True.  But in my workflow, I want all the manuals I need to be
available simultaneously, so they can be displayed side by side when I
need that.  YMMV, of course.

This is apparently irrelevant to the OP.

Before `g (dbus)' you can type `M-n' (`clone-buffer').

Or type `C-u g (dbus)' and it will display a new Info buffer
with the name "*info-(dbus)*".
