I've added the following during the pGnus days:

(add-to-list 'mm-inline-media-tests '("text/html" nil (lambda (h) nil)))
(add-to-list 'mm-discouraged-alternatives "text/html")
(add-to-list 'mm-discouraged-alternatives "text/richtext")
(add-to-list 'mm-discouraged-alternatives "text/enriched")
(setq mm-automatic-display (remove "text/html" mm-automatic-display))
(setq mm-automatic-display (remove "text/richtext" mm-automatic-display))
(setq mm-automatic-display (remove "text/enriched" mm-automatic-display))

It doesn't handle all possible, broken ways HTML can get to you but it
helps a bit.

(Improvements that doesn't involve W3 or similar are welcome.)

Hi,

This approach seems to best fit my need.  How do you hook
my:gnus-html2text into gnus so that it is run automatically on
html mail?

Thanks.

And after a few changes, it works fine for me, too.  Thanks!

Here everything together:


(defun my:gnus-html2text (handle)
  (let (text)
    (with-temp-buffer
      (mm-with-unibyte-buffer
	(mm-insert-part handle)
	(save-window-excursion
	  (my:html2text-region (point-min) (point-max))
	  (setq text (buffer-string)))))
    (mm-insert-inline handle text)))

(defun my:html2text-region (min max)
  "Replace the HTML region from MIN to MAX with lynx --dump."
  (interactive "r")
  (let ((file "/tmp/email.html"))
    (unwind-protect
	 (progn
	   (write-region min max file)
	   (delete-region min max)
	   (insert (shell-command-to-string
		    (concat "lynx "
			    "lynx -dump "
			    (shell-quote-argument
			     (expand-file-name file))))))
      (delete-file file))))

(setq mm-inline-media-tests
      (cons '("text/html" my:gnus-html2text
	      (lambda (handle)
		(fboundp 'my:gnus-html2text)))
	    (let ((old (assoc "text/html" mm-inline-media-tests)))
	      (if old
		  (delete old mm-inline-media-tests)
		  mm-inline-media-tests))))

(See Robin Socha's mail in a similar thread pointing to the page: 
http://my.gnus.org/Lisp/1012919677 )

[1] I was missing the 'credits' line in my .gnus---apologies for that.
i now see that that code was written by Mark Thomas.

[2] The code is perhaps now improved further on that page. 

[3] in any case, The code may have now been rendered obsolete (?) ---
the page says so.. (by gnus-art.el?)
