multiple mailcap entries

multiple mailcap entries

[Klaus Zeitler]

On my Solaris workstation I use qvpunix to read msword and excel files.
I've used the following entry in my .mailcap file to read msword files
automatically, when I press enter on a msword attachment:

 application/msword; qvpunix -mn %s

This has been working fine. Now I tried to do the same for excel files
and added:

 application/octet-stream; qvpunix -mn %s

But this doesn't work, instead gnus asks me where to save the attachment.
The difference between these to entries seems to be that the variable 
mailcap-mime-data contains (amongst many others) only one entry for
application/msword , but 2 for application/octet-stream:

(("application"
  ("octet-stream"
   (viewer . "qvpunix -mn %s")
   (type . "application/octet-stream"))
  ("msword"
   (viewer . "qvpunix -mn %s")
   (type . "application/msword"))
  ...
  ("octet-stream"
   (viewer . mailcap-save-binary-file)
   (non-viewer . t)
   (type . "application/octet-stream"))
  ...))

and function mailcap-mime-info returns mailcap-save-binary-file as viewer
for "application/octet-stream", i.e. the 2nd entry.

I thought that entries in ~/.mailcap would have highest preference, but it
seems to be the opposite. It seems that I have to modify the variable
mailcap-mime-data instead or do I miss something?

Yes, ~/.mailcap entries are normally preferred.  There is one exception,
though, internal Emacs functions (such as `mailcap-save-binary-file')
are always preferred over external commands.

Me too.  This is also the right way according to RFC 1524.

What is it about the ordering, that doesn't make sense?

It looks like "Choose user-preference first, then go systemwide -
preferring the most global existing mailcap", to me?

Don't agree. IMHO we should keep this ordering.

I have never heard of such a convention. IIRC, FHS doesn't mention
/usr/(local/)?/etc at all.

IMHO, if I have both /usr/local/etc/aa.conf and /etc/aa.conf, that's
wrong by itself and I shouldn't care much about the sequence.

The reason to have /etc/mailcap before /usr/local/etc/mailcap is: it's
more standard and frequently used.

Why not invent a ~/.mailcap.el and put it at the beginning of the
search path?

That way it doesn't matter whether it is an internal or external
command. If the command is specified in ~/.mailcap.el it is the
command that is to run from emacs.

No :

gnus-treat-leading-whitespace's value is nil

I am really clueless.

Is it worth that I upgrade to the latest Oort release ?
