w3 trouble

w3 trouble

[Björn Lindström]

I have some trouble with w3 and Emacs 21.3.1. When I try to open a page
I get this error:

set-face-attribute: Wrong type argument: stringp, nil

And when I try to view HTML mails/RSS posts in Gnus I get this, followed
by Gnus showing the post with tags and all:

Parsed 100% of 148...done
Drawing... \
Error while rendering html; showing as text/plain

This is very weird, since it worked up until a couple of days ago, and I
can't remember changing any settings that might have affect this. Clues,
please?

Since nobody seems to be able to answer this, could maybe someone share
their working w3/gnus settings, so I could try them out?

First, I have only: GNU Emacs 21.2.1

Then, I have quite a lot of settings that might affect.

First old Xresources:

Emacs*w3-tt-style.attributeFont:	-adobe-courier-medium-r-normal--12-120-75-75-m-70-iso8859-1
Emacs*w3-header-style.attributeForeground:	AntiqueWhite2
Emacs*w3-italic-style.attributeFont:	-adobe-courier-medium-o-normal--12-120-75-75-m-70-iso8859-1
Emacs*w3-node-style.attributeForeground:	CadetBlue2
Emacs*w3-visited-node-style.attributeFont:	-adobe-courier-medium-o-normal--12-120-75-75-m-70-iso8859-1
Emacs*w3-visited-node-style.attributeForeground:	CadetBlue3

Then some things at various levels in my emacs-lisp files:

(custom-set-faces
 '(cperl-array-face ((((class color) (background dark)) (:bold nil :foreground "wheat" :background "DeepSkyBlue4"))))
 '(widget-button-pressed-face ((t (:foreground "CadetBlue3"))))

 '(message-header-name-face ((t (:foreground "Goldenrod"))))
 '(message-header-cc-face ((t (:bold t :foreground "LimeGreen"))))

It didn't seem to break anything, in any case.
Once I was there, I "Customized" a bit the defaults.

Thanks for all that. But nothing of that really affects Gnus, or does
it?

This is all the settings I have that concerns w3:

(require 'w3)

; Open links in Gnus articles with browse-url.
(eval-after-load "w3"
  '(progn
     (fset 'w3-fetch-orig (symbol-function 'w3-fetch))
     (defun w3-fetch (&optional url target)
       (interactive (list (w3-read-url-with-default)))
       (if (eq major-mode 'gnus-article-mode)
           (browse-url url)
         (w3-fetch-orig url target)))))

Viewing HTML in Gnus with this used to work alright, but now it
doesn't. Is there anything else I might need?

Is there anything I can do to make w3 give some more helpful error
messages than the

Parsed 100% of 240...done
Drawing... \
Error while rendering html; showing as text/plain

stuff?

You might like advice.el:


(defadvice w3-fetch (around gnus-browse-url activate)
   "Open links in Gnus with `browse-url' instead."
   (if (eq major-mode 'gnus-article-mode)
       (browse-url (ad-get-arg 0))	; URL
     ad-do-it))

Yeah, I might, if I got w3 to show anything at all.

I gave up on getting w3 to work, and installed emacs-w3m instead. Now I
would like to know how to translate any of the snippets above for use
with emacs-w3m instead of w3.

(setq browse-url-browser-function 'w3m-browse-url)

Thanks, but that wasn't what was I was after. I want links in mails
viewed by emacs-w3m, in Gnus, to open with browse-url-browser-function
(Firebird, in my case).

And my point is that the snippets merely cause Gnus to call browse-url,
which should do what you want if browse-url-browser-function is set to
the right emacs-w3m function.  Does it?  If not, what happens?

I don't really understand your question. Anyway, the problem is that
following links in w3m in Gnus, does apparently nothing, except for
showing the URI in the message buffer.

Sorry, I can't help you.  Maybe you should ask over on gnu.emacs.gnus?

Which version of W3 have you got?  I think *pre46 is not enough, you
need *pre47.

You could also try the version from CVS.  Search for a w3 project on
savannah.gnu.org.  That should give you the CVS downloading
instructions.  (If you go that route, you'll need to download another
project, "url", first!  It was split out from W3, and W3 depends on
it.)

I have w3-4.0_pre47. Do you think it will help to get the CVS version?

Hm.  I don't really know.  I remember that I used the CVS version and
it worked.  But that was around the time when *pre47 was created. 
Since then, I've been using emacs-w3m.

If it isn't too much trouble for you, I suggest to try.  Then at the
worst you have wasted 15 minutes.

That's what I did, too.

If there is no word on what was wrong, I think I'll just keep using
emacs-w3m.
