How to get info pages for Emacs?

How to get info pages for Emacs?

[KARR, DAVID]

I've got Cygwin Emacs 24.5.1 on my desktop and Emacs 24.3.1 on my CentOS 7 VM.

If I open the main "info" node on each, I see an "Emacs" node on the first, but not on the second.  How do I get the missing Emacs info pages on my CentOS 7 VM?

There's a couple of things I can think of.  First off, is there an
"emacs-doc" package for Centos?  If so, is it installed?
Honestly, I don't think this is the problem, since emacs' info
file should be part of the emacs package, but it's easy to check:

    yum list emacs-\* | grep -i doc

Next, check in "/usr/share/info" for the file "emacs.info".  If it
isn't there, try re-installing emacs.  If it is there, check the
same directory for the file "doc", which is the top-level node for
Info.  It should have the lines:

    Emacs
    * Emacs: (emacs).

(possibly more) in there, under Editors.

Beyond that, I'm lost.

I hope this helps.

% ls *emacs*
emacs-gnutls.info.gz  emacs.info.gz  emacs-mime.info.gz

% ls *doc*
ls: cannot access *doc*: No such file or directory

However, if I run "info emacs" from the command ilne, it brings up the Emacs info node.  It's just Emacs that can't find its own info page.

That file is called "dir".

Ok, that's helpful.
------------------
% ls -lt dir emacs*
-rw-r--r--. 1 root root  83214 Jun  3 13:31 dir
-rw-r--r--  1 root root  10853 Jun  9  2014 emacs-gnutls.info.gz
-rw-r--r--  1 root root  28148 Jun  9  2014 emacs-mime.info.gz
-rw-r--r--  1 root root 651392 Jun  9  2014 emacs.info.gz
-------------------

However, the "dir" file doesn't have the main Emacs nodes.  It looks exactly like what I see in Emacs.

That file is actually named "dir".

What's the value of `Info-directory-list'?  I guess it doesn't contain
/usr/share/info/, and then that's the problem.  That variable is
documented to be initialized from `Info-default-directory-list', so
what's the value of that variable?

Yeah, I didn't think there would be.  As I said, emacs.info is
supposed to be included in the emacs package.

Interesting.  There is no /usr/share/info/doc file at all?  What
does info show you when you run just "info" from the command line,
without specifying a subject?

I'm running Fedora 21, which shouldn't be much different from
Centos.  To me, this looks like a packaging error on Centos' part.
So far as I know, /usr/share/info/doc has to be there; it's the
top-level info node.  (I could be wrong, of course; if so, I hope
someone more knowledgeable will jump in here.)

Strange.  I think that file is used both by info on the command line and
by emacs, so you should get the same index in both.

Anyway, normally the package manager should update the dir file when
packages get installed or removed but that doesn't seem to have happened
on your system for whatever reasons.  But you can do that manually, too:

  % install-info info-file dir-file

adds an entry for the given info-file in the given dir-file.  So you can
do that for the missing files and hopefully that will resolve the issue.

That variable isn't even defined.

I guess this is consistent, as it looks like what I get from Emacs, with none of the Emacs info.

It should be defined after info has been loaded, e.g., after you've done
`M-x info' or `C-h i'.

Ok, well, that fixed it.  I can now see the Emacs info both from the command line and from within Emacs, and the variable is set and correct.  It seems likely this was some sort of flaw in the image assembly.  I'll first ask the person who gave me access to this image.  We'll see how far he can take it.

Thanks, Tassilo.  I was completely ignorant of those variables.
My dealings with Info are limited to reading the docs.  (Fedora's
packaging seems to always put things in the right place.)  I've
never tried to build an info file myself.

When you specify a manual on the command line using info, like "info
emacs", info will search the relevant files like /usr/share/info for the
specified file.  It doesn't have to be mentioned in the dir file.  But,
if nothing is specified then the dir file is used and if there's no
entry for an info file then nothing is shown.  Emacs works the same
way.  Before you edited your dir file if you'd have done (info-display
manual "emacs") it would have worked.

The underlying problem is that the package manager should have called
install-info for you.  The installation script isn't complete.
