Hi,

when visiting .info files in Emacs via find-file Emacs opens the file in the
default major-mode instead of Emacs' info-mode. I suggest therefore to add the
following default-association:

 (add-to-list 'auto-mode-alist '("\\.info\\'" . info))


HTH,

Geralt.

This doesn't work for me.  However, the following does:

(add-to-list 'auto-mode-alist '("\\.info\\'" .
              (lambda () (interactive)
                (info (buffer-file-name)))))

I think this has too bad consequences: it visits the Info file,
but doesn't display it.  Instead, it displays another buffer
with the Info manual.

Maybe `dired-info' from `dired-x.el' is more suitable for your needs?
At least, it doesn't visit the Info file.

The value of major-mode in an Info buffer is Info-mode:

(add-to-list 'auto-mode-alist '("\\.info\\'" . Info-mode))

This doesn't work too.  It seems `Info-on-current-buffer' was created
exactly for the purpose to be associated with .info in auto-mode-alist.
It is not used anywhere else.

Yes, I wrote Info-on-current-buffer specifically for this kind of use,
but no it doesn't work for the auto-mode-alist, really.
There is no good reason why it can't work for auto-mode-alist, but it's
the way it currently is.  Patches welcome,


        Stefan

That doesn't work either: even if the file is editable, the buffer is read-only.

It should be something like:

(lambda ()
   (let ((Info-enable-edit buffer-read-only))
     (Info-on-current-buffer)
     (when Info-enable-edit
       (Info-edit))))

Definitely not.  `Info-edit' is not recommended to use according
to the docstring of `Info-enable-edit'. It is disabled by default.
Your code overrides its default value.

Oops, I meant (let ((Info-enable-edit (not buffer-read-only)) ...)

That is a good default, because normally one is viewing an Info file via
`C-h i' (including `C-u C-h i').  But if one has explicitly visited a file
via `find-file' and friends, then The Full Power of Emacs Shall Be at Your
Fingertips.  :-)

Only temporarily.

That's not necessarily a problem.  Several major modes put their buffer
in a read-only mode even if the underlying file is writable.  This is
typically the case for modes that change the appearance of the buffer
(use things like after-string and display properties).

I think in the case of Info buffers, it's perfectly OK to open them in
read-only mode even if the file is writable.

I see only one problem with using Info-on-current-buffer for the
auto-mode-alist.  Since it can't read the node name interactively,
it defaults to `Top' that may be missing in the current file of the
multi-file Info manual.  Perhaps it should default to the first node of
the current file.

I think it would be a bad idea to open in Info mode, since one
occasionally comes across plain text files with the .info extension.
Anyway, we have the `info-display-manual' command for this now.
Closing.

To say nothing about "C-u C-h i", which we had for ages.
