attaching a file in dired mode

attaching a file in dired mode

[Eythan Weg]

Hi,

When I use  gnus-dired-attach while the cursor is on a
file in dired buffer it results in 
 
       Invalid function:   gnus-setup-message

Attaching a file works  correctly when a mail
buffer  exists.

What should be expected?

I use gnus in a recent cvs emacs

Thanks, Eythan

This happens with Gnus bundled with Emacs.  `gnus-setup-message'
is a macro that should be provided when compiling gnus-dired.el,
however I realized it is not loaded when compiling gnus-dired.el
along with Emacs (no problem when performing `make' on No Gnus).
I've fixed it in the Emacs trunk as follows:

Note: using `eval-when-compile' generates useless warnings.

This is bug 1060.

For me, this has the problem described in bug #1060:

emacs -Q
C-x d
M-x turn-on-gnus-dired-mode

just sits there showing the Gnus logo (though it does seem to work if
one just kills the logo buffer).


Oh, but I see you installed a different change. This has the other
problem described in bug 1060:

emacs -Q 
C-x d
M-x turn-on-gnus-dired-mode
mark file
C-c C-m C-a

void-variable gnus-article-reply



Note one of the goals of FOR-RELEASE is to "minimize Gnus dependencies
in gnus-dired.el" (see also the comments in gnus-dired: "These are
used only if the user customizes `gnus-dired-mail-mode' to use Message
and/or Gnus"). So it would be nice if gnus-dired did not
unconditionally require other Gnus features.

Oops.  So, what I did was only having fixed the byte code that
was made so as to funcall a macro symbol.  I didn't think that
gnus-dired.el is used without launching Gnus.  But I may not be
wrong at least in `C-c C-m C-a' (gnus-dired-attach).  Why one
wishes to use `C-c C-m C-a' is that one wants to use one's Gnus
configuration for message sending, message archiving, etc.  So,
it is not unreasonable requirement that one has to run Gnus in
advance, is it?  How about making it stop with a warning like
"You must run Gnus first"?

OTOH, `report-emacs-bug', if `mail-user-agent' is set to
`gnus-user-agent', loads many Gnus modules, but doesn't necessarily
require running Gnus.  If `gnus-dired-attach' has to be improved
to get to be like it, it will take time.  I don't feel like doing
it very much, though.

For the other gnus-dired features, `gnus-dired-find-file-mailcap'
and `gnus-dired-print', they have no inevitability to be prefixed
with `gnus-', I think.

I didn't follow the discussion, but I think rms wants gnus-dired to be
capable of (optionally) working without the rest of Gnus.

That's probably fine, if the message says something like:
"You must run Gnus, or customize `gnus-dired-mail-mode', first"

Or, how about something like changing the default value of
gnus-dired-mail-mode to something like:

(if (featurep 'gnus) 'gnus-user-agent
  'mail-user-agent)

(It's possible none of this makes sense, I'm not familiar with how
this works...)

At last I discovered what causes the Gnus logo screen.  That is
the following snippet that has been put in gnus.el:

(eval-when (load)
  (let ((command (format "%s" this-command)))
    (when (string-match "gnus" command)
      (if (string-match "gnus-other-frame" command)
	  (gnus-get-buffer-create gnus-group-buffer)
	(gnus-splash)))))

It is evaluated when gnus.elc is being autoloaded.  Note that
what causes that autoloading then is `gnus-dired-attach', of
which the name matches "gnus".  So, how about faking the value
of `this-command'?  The patch is below.  Could you try it?

> emacs -Q
> C-x d
> M-x turn-on-gnus-dired-mode
> mark file
> C-c C-m C-a

This works well for me.  I don't know why I don't observe bug
1060, i.e. ``void-variable gnus-article-reply'', though.  Do you
still get that error?

In addition, `gnus-dired-attach' seems to have been written
before I improved Gnus' `compose-mail' handling.  Now it should
work with `gnus-user-agent' and the `gnus-setup-message' macro
is not necessary.

It works just fine for me, thanks!
