Hi all,
In the attached patch I add a new command for org-attach: save *all*
attachments from the current Gnus article to the current org-attach-dir.
(Sorry for repeating the word "attach" so much :-))
NB:
1. If no Gnus article is open, it returns an error message.
2. I've only tested it on Emacs 28. I don't know if it can cause any
problems on earlier Emacs/Gnus versions.
3. Although there are several alternatives to Gnus, I have chosen Gnus
specifically because it is part of GNU Emacs.
4. I think an option could be added to save only certain types of files
(pdf, png, jpg, docx, etc.).
Best regards,
Juan Manuel

I think that supporting only Gnus is too specific. Not all the people
use Gnus as mail reader. And the extra menu option you propose will only
eat up space for people not using Gnus.
I'd prefer a more generic approach working in any kind of email reader,
be it rmail, gnus, mu4e, notmuch, or wunderlust. The approach can
probably making use of message-mode or MML libraries from Emacs core.
Also, I do not like adding yet another menu option even if it is working
for other mail readers. Instead, it would be more consistent to follow
what we do for dired. See interactive spec in org-attach-attach.
Best,
Ihor

Well, as I said, I have chosen Gnus because it is part of GNU Emacs. In
any case, if anyone wants to write a patch with a more general solution,
I'd encourage them. I think that would be an interesting feature for
org-attach. I only use Gnus and unfortunately I'm not familiar with
other mail reader libraries (I could try to do something more "agnostic"
from message-mode, when I have some more time...).
What I don't quite understand is why it wouldn't be appropriate to add a
new entry with the new feature to the org-attach menu.
Best regards,
Juan Manuel

Thinking about it more, new feature in org-attach menu should actually
be ok.
My initial logic was that we cannot easily select attach method for
entries in the attach menu. However, anything other than 'cp method is
meaningless when saving article attachments.

I think that a good example implementation is from notmuch.el. It does
not use anything specific to notmuch, just built-in mm-*.el from gnus:
(defun notmuch-save-attachments (mm-handle &optional queryp)
(notmuch-foreach-mime-part
(lambda (p)
(let ((disposition (mm-handle-disposition p)))
(and (listp disposition)
(or (equal (car disposition) "attachment")
(and (equal (car disposition) "inline")
(assq 'filename disposition)))
(or (not queryp)
(y-or-n-p
(concat "Save '" (cdr (assq 'filename disposition)) "' ")))
(mm-save-part p))))
mm-handle))
(defun notmuch-foreach-mime-part (function mm-handle)
(cond ((stringp (car mm-handle))
(dolist (part (cdr mm-handle))
(notmuch-foreach-mime-part function part)))
((bufferp (car mm-handle))
(funcall function mm-handle))
(t (dolist (part mm-handle)
(notmuch-foreach-mime-part function part)))))
Best,
Ihor
