I think it is possible to add a test in .mailcap -- you only need to
find out what is the syntax and what is a test that passes in Gnus but
fails in Netscape.

Anyone?

The format is defined/suggested in RFC 1524:

Ah.  The easiest solution seems to be to put (setenv "EMACS_RUNNING"
"1") in the ~/.emacs file and then test this environment variable.

Re: Adding MIME viewer to variable instead of .mailcap

[Jake Colman]

Sorry to jump into this thread but how do I use .mailcap to get gif or jpegs
to automatically view through an external application instead of internally
in the XEmacs article buffer?

I do have the following entry in my .mailcap

        image/gif; xv %s

yet the images always display inside the buffer?

Actually, what I really want is that images that are too large to fit in the
buffer should be displayed by xv, otherwise they should be displayed
internally to the buffer.

Thanks!

...Jake

After M-x shell RET you can type `echo $EMACS' with interesting
effects, but this variable is not present in process-environment, and
M-! echo $EMACS RET doesn't look promising.

Well, Gnus reads .mailcap and puts the findings in mailcap-mime-data,
which you can then frob to your heart's content.

This is only mildly related to your question, but I think Emacs defines
the environment variable EMACS to `t' at least within the shell spawn
through `M-x shell'.  I'm using EMACS from login to hold the path to the
Emacs executable I want, and Emacs was overriding the value with `t',
breaking some later scripts called from within Emacs.  After I reported
the problem, Richard told me he was to leave the variable undisturbed if
it already existed (if I remember correctly, this was a while ago).

You need to remove the stuff you don't want inlined from the
`mm-inlined-types' variable.

Setting gnus-mime-multipart-functions could probally solve you
problem:

  gnus-mime-multipart-functions's value is 
  nil

  Documentation:
  An alist of MIME types to functions to display them.

  Defined in `gnus-art'.
