MIME handling for common MS Windows attachments?

MIME handling for common MS Windows attachments?

[John Cooper]

[NT Emacs 20.3.1, Pterodactyl Gnus v0.69]

By default pGnus doesn't seem to offer to attempt external display of common
Microsoft attachments, e.g., MS Word (MIME type application/msword), excel,
powerpoint, etc.

I just created the following entry in ~/.mailcap which allows word files to be
launched:

application/msword; C:/Progra~1/Micros~1/Office/WINWORD.EXE %s

  [Note: my shell-file-name is cmdproxy and using spaces in the path failed]


Is it intended for pGnus to eventually support many Windows file types OOTB?
If not, has anyone put together a comprehensive .mailcap for many of these?

Thanks,

    --- John

I still think relieving users by defaulting ms-word to MS Word
viewers, etc., might be useful, even if strictly against FSF's
philosophy.

I think so, to.  Defaulting *.doc to ms-word is bad, but I see no harm 
in defaulting application/ms-word to MS Word (or something else that
can understand these files).

Could someone who uses stuff like that mail me a patch for mailcap.el?

A more sticky issue is whether to default image/* to the un-free, but
commonly installed xv, or to some free image viewing program.

What image viewing programs exist out there?

(Well, it isn't really a sticky issue, because we could default to
free programs, and then use non-free programs as the backup default
values if the free programs don't exist on the system.)

xli and ee (from GNOME).

I've now asked around, it seems things are not as easy as I thought.
If we discount the giant stuff such as StarOffice (and, of course, The
Real Thing on Windows-running Emacsen), a useful default can be
constructed.  There is an `mswordview' that can grok *some* of the
Word formats (only Word 97, I'm told.)  We need to do the following:

1) Look at the contents of the part, and see if it is something
   mswordview can grok (one should study mswordview source to see how
   this is done).

2) If yes, then invoke mswordview which will produce HTML.  Feed the
   resulting HTML to W3.

3) If mswordview cannot grok it, it displays a list of other programs, 
   which supposedly can.  We should look into using them.

Not a bright future, all in all.

The trouble is that xv is much better than most of the other stuff out 
there, especially for 8bit displays.  Defaulting to free stuff might
be a politically good idea, but it's a lousy choice for users.

> What image viewing programs exist out there?

There is imlib/gtk-based gqview, then there's ee (Electric Eyes) (also
imlib-based), ImageMagick's display (it produces high quality display,
but it's very slow, making it unsuitable for MIME viewers).

Lars knows that.  Read carefully: "un-free, but commonly installed xv".

Here's what I've saved up links for:
	<URL:http://word2x.alcom.co.uk/>
	<URL:http://www.gnu.org/~caolan/docs/MSWordView.html>
	<URL:http://www.ice.ru/~vitus/catdoc/>

Word2x attempts to convert Word documents to either HTML, TeX or plain 
text, while preserving as much of the structure as possible.  Seems to 
support at least Word 6 and 7.  MSWordView does indeed support only
Word 8 (Office97) and has HTML as its only output.

catdoc is simpler, and aims at just preserving the text from the Word
document.

This hasn't been my experience; ImageMagick is enough better than xv that
I never use xv any more.

This surprises me.  I've found ImageMagick relatively competative with xv
for most images.  It's a good bit slower when it has to dither 24-bit, but
that's not the common case for a MIME viewer, surely.  And the quality
difference is noticeable.

I'll point out as an aside that xv doesn't appear to deal at all well with
virtual desktops, tending (at least for me) to put the popup window in the
upper left corner pane.  ImageMagick correctly displays the image in the
current pane.

I keep hearing about IM, but I'd never used it, so I just experimented
a while with it.  Woof -- I thought xv was memory intensive:

USER       PID %CPU %MEM  SIZE   RSS TTY STAT START   TIME COMMAND
karl      7932  8.5 11.0  8308  6944  p2 S    08:30   0:01 xv .pict/s/ssf-nasa.j
karl      7935 46.7 31.4 22284 19828  p2 S    08:31   0:05 display .pict/s/ssf-n

19Mbytes resident, just to display *one* .jpg?  3 times xv's already
large requirements?  Sure, the image is 1280x1024 and 227Kbytes.  But
/really/ now.  Even with a puny 333x800, 33Kbyte image, xv weighs in
at 4Mbytes while display punishes the scales at 7.8Mbytes.

I'll stick with xv; my machine pages hard enough as it is.

(General IM operational gripes: Why can't I type `q' on the image to
make the program exit, or get a nice directory listing that doesn't do
some weird thumbnail thing when I select an image from it?  [I want a
listing such as one gets in an xv controls window -- general
selectability, without thumbnailing.]  And just what is the supposed
mnemonic value in having Transform->Flop as horizontal swap while
Transform->Flip is vertical swap -- I'm supposed to remember this sort
of cuteness?  Also, the "image info" window's presence prevents
anything else from being done until you dismiss it -- but often I want
xv's info window to remain across images.  This UI needs help.)

My offhand suspicion is that you're using an old window manager.  xv
pops up windows wherever I am under fvwm2, for example.  But I
remember tvtwm suffering that sort of problem.

I don't think so... I can easily see people passing around jpegs from
their scanner/digital camera.  In fact, I tend to think more people will
be passing around 24-bit images than 8-bit.

How about defaulting to running "start" on Mickeysoft platforms, which will
generally Do The Right Thing, and will allow users to change things
without having to mess with mailcap files ? (but have mailcap be
preferred, obviously).

  Even better would be the ability to sniff the registry for the
appropriate mime viewer directly.  But using 'start' would be a good
start. :)

I think defaulting .doc to ms-word is good when running under Win32.

Anyway, Debian Linux has an /etc/mime.types file that does what
mailcap.el's mailcap-mime-extensions does.  I'm not sure how Debian
specific it is, but are people open to having Gnus look for it (or
maybe a ~/.mime.types file)?

I assume that files like /etc/mailcap override Gnus' defaults?

  The old 'mm.el' stuff that lars based his mime decoding stuff on
supported this.  This is a very standard file, dating back to the dark
ages. :)

If you make it selectable, I don't mind if xv is first (apparently other
people have a very different experience than I do).  Just as long as it's
selectable.  :)

I'm currently able to send application/msword attachments to Word; however, I
also get a lot of Word attachments from Outlook users with a MIME type
application/octet-stream, which I now manually save to disk and then invoke
`cmd /c start' on them from a zsh shell window.

How easy would it be to add a new "MIME part" menu option "Save and start...",
which calls "start" (or "cmd /c start") on the saved file?  This would make
launching attachments in NT Emacs much more convenient.

If I select the "View Interactively" menu and enter `winword' when prompted for
Viewer, Word starts up displaying an empty document.  I seem to need to type
the following value for Viewer:

  winword<C-q><SPACE>%s

.. to get it to work.  Shouldn't Gnus add the ` %s' suffix by default?

I'd rather not have the default start things like word or excel
automatically. Doing it on a button-click is of course ok. But to

I should have said "default to running start when the user clicks on
a button". I wasn't advocating automatically starting the viewer
(unless that's what the user wants, of course). (setq-default
gnus-mime-allow-gaping-redmond-security-hole t) anyone? ;-)

You can either select it via `View Interactively...', or override it
in your own .mailcap, e.g. like this:

image/*; YOUR-VIEWER-HERE %s

Indeed.  Whether displaying it automatically or not -- doing things
that are known to be dangerous without warning gives me a bad vibe.

Most of the other viewers are "harmless" -- xv is unlikely to execute
parts of the data contained in pictures.  The Microsoft "viewers" are
all infamous for executing whatever you throw at them.

  So then I assume we pass -dSAFER to ghostview or ghostscript?  Wouldn't
want a postscript attachment deleting, renaming, or overwriting files. :)

  I know XV does this by default when viewing postscript files.

Thanks for the reminder; you're right I missed the point ;-(
