gnus-mime-view-all-parts fails in 1.14

[Christopher Gray]

I have gnus-mime-view-all-parts bound with 

(add-hook 'mu4e-after-view-rendered-hook

(keymap-set mu4e-view-mode-map "s-<f12>"
                      'gnus-mime-view-all-parts))

and this worked in  1.12 to render an an image tagged like this

<img id=3D"mailpiece-image-src-id" style=3D"pa=
dding-top:15px;" src=3D"cid:1113274109-011.jpg" alt=3D"Mailpiece Image">

but 1.14 gives the error funcall-interactively: No buffer named *Summary*

It was by accident that it worked I guess... But you could try
binding to something like the following instead:

--8<---------------cut here---------------start------------->8---
(defun my-gnus-mime-view-all-parts (&optional handles)
(interactive)
(get-buffer-create "*Summary*")
(gnus-mime-view-all-parts))
--8<---------------cut here---------------end--------------->8---

Kind regards,
Dirk.

It was by accident that it worked I guess… But you could try binding to something like the following instead:

–8<----------–—cut here----------–—start--------–—>8— (defun my-gnus-mime-view-all-parts (&optional handles) (interactive) (get-buffer-create "Summary") (gnus-mime-view-all-parts)) –8<----------–—cut here----------–—end----------–—>8—

Kind regards, Dirk.

I had a similar problem: I had bound gnus-view-part-externally to SPC in gnus-mime-button-map (essentially so that I can preview an attachment without saving it anywhere permanent), and it had stopped working in 1.14 with the same error message ( funcall-interactively: No buffer named Summary).

Your fix above worked for me, but I was interested in learning more about the background: why did the 'vanilla' gnus-view-part-externally command work before 1.14? And is there a more mu4e-idiomatic way of previewing an attachment without saving it?

All the best, Matt

That works! Thank you.
