Gnus not showing article

[Robert Epprecht]

I'm running actual CVS Gnus in GNU Emacs 20.7.2 on a Linux text console.  

Quite often when I follow mailinglist discussions I enter an article and
see...  nothing.   Why?

Maybe Gnus is trying to display the text/html part but you don't have
W3 installed?  Hm.  What happens when you hit `K b' on the message?
Can you then click on the other alternative and have that shown?

It might also help to say

    (require 'mm-decode)
    (add-to-list 'mm-discouraged-alternatives "text/html")

But I think that Gnus should do something useful even without this.

Oops, I'm not a native speaker ;-)
Thought you could say that [searching dictionary]... can't you?

Yes, that's probably the case.
(My attempt to install W3 failed last time, I'll try again).

I'm a bit confused about W3 and Emacs/W3 (hope I got the names right)
Which one do I want for the text console and GNU Emacs 20.7?

Yes, that works fine, thank you.

When I select the alternative I get 
'Displaying gnome-help-browser '/tmp/emm.2663yF/mm.266E9L'...'
Looks as if my (Debian) installation is broken somehow, as I do
not use Gnome (but had tried it once).

Yes, that works.

Thank you for your help.

Either one can be correct depending on what you intend to convey.

`actual cvs gnus' could mean simply any version of cvs gnus since cvs
began, which would allow some quite old versions.

current cvs gnus would define it to be the most recent version of cvs
gnus. Or at least a very recent version.

Actual == real.  So an actual Gnus version would be something which
released, as opposed to a hypothetical version which people only talk
about.

There's only one Emacs/W3 and it goes by the name of W3 :-)
I guess w3-4.0pre46 (or some other number after pre) would be the
right one for Emacs 20.x.

Maybe you can do dpkg --purge on the gnome packages, that will delete
the config files, too.

If you put something like the following in ~/.mailcap, Emacs ought to
use Netscape:

    text/html; netscape %s

>> But I think that Gnus should do something useful even without this.

It's now clear that this is an issue outside of Gnus' control.  After
all, Gnus can't know that you have gnome-help-browser in your .mailcap
or mail.cap even though that program doesn't exist.

And for W3?
What if I want W3 on the console (normally) and netscape in X (rare)?

Yes, I found it in /etc/mailcap

Gnus automatically uses W3 when it is installed, even with the above
entry.

If you want to tell Gnus not to use W3, even when installed, you have
to frob the variable mailcap-mime-data.  It contains this entry:

 ("text"
  [...]
  ("html"
   (viewer . mm-w3-prepare-buffer)
   (test fboundp 'w3-prepare-buffer)
   (type . "text/html")))

I think you can just remove it.
