Hello

Now that the bug in org-mime-htmlize is fixed, I would like
to comment on the visual representation. Most likely this
has to do with the mml package.

When I write the following message 
Integral


$$\int fdx=0$$
And


\begin{equation} 
\sum_{\alpha} 
\end{equation}

and apply org-preview-latex-fragment and then
org-mime-htmlize and send this message to gmail. 
The 'gmail-reader' displays them fine.

However thunderbird does not and I apply the resulting eml 
file below (I presume a screenshot is not appropriated)

Now tunderbird itself has an extension (latex-it) which does
something similar to org-mime-htmlize, it sends latex math
as png. However there are "better* displayed, I attach the
relevant eml file below.

Could org-mime-htmlize use the structure of latex-it?

Thanks 

Uwe Brauer

This sounds like a thunderbird bug -- not properly displaying multi-part
messages.

The difference between org-mime-htmlize and latex-it is that the former
converts each formulas to its own png image, while the later converts
the entire message to one large pdf file which is then attached as a
single image.

The ability to convert the entire message to one monolithic image
(through latex and pdf) could certainly be added as an export option
(patches welcome), but I would not want this behavior to be the default,
as sending messages as large images is not (to my mind at least) a
desirable option.

yes and no: latexit can do what you describe (and the author admits that 
it only makes sense for documents whose size does not exceed one page. 
latexit can also embed in html pages latex formulas, however only
$$ are allowed no equations (which makes it inferior to 
org-preview-latex-fragments)

In any case I attached the wrong eml file (the one with just one page) I 
now attach the eml with the embedded formula. Maybe some useful 
information can be extracted.

I'm not clear on how this differs from the messages produced using
org-mime-htmlize, and it has been a while since I've looked into email
mime mechanics.  However, since the emails generated using
org-mime-htmlize display correctly in Gmail and in gnus I'm inclined to
say that this is a Thunderbird issue and leave it for them to debug.

Sorry I'm not more helpful,

I send a bug report to the Thunderbird developer and the
answer was that *one* source of the problem is 

,----
| Here, the message has a multipart/mixed structure at the top
| with "cid:" references to the image/png part which is inside
| that structure (the text/html part is correctly in a
| multipart/alternative but there is no multipart/related;
| both images are in the multipart/mixed context). Also, the
| images have a "Content-Disposition: attachment", both
| reasons to show them as attachment as Thunderbird does it.
| 
| Now it seems that Gmail completely ignores multipart/related
| vs. mixed and simply takes the reference regardless of that
| context, which would explain what you see. Strictly
| speaking, the message is incorrectly formed. Please file a
| bug with Emacs, the latexit structure appears to be correct.
`----


So how could "Content-Disposition: attachment" be changed to
"Content-Disposition: inline" in your code? I can't find the
relevant piece of code.

Thanks

Uwe

Hi Uwe,

Thanks for sending along this helpful review.  I've just pushed two
changes to org-mime so that it now (1) wraps html and images in a
multipart/related mime structure and (2) marks images as "disposition
inline" so that they don't show up as attachments.

I can confirm this new version works in gnus and in the gmx webmail
client as expected, but I don't have access to Thunderbird to check the
behavior there.  Please let me know if this fixes the problem.

Thanks,

Hi Eric, 

Thanks for your efforts. I have good and bad news. The bad
news is your changes make things worse in Thunderbird, for
reasons I don't understand the header of the resulting
messages reads:
Content-type: text/plain; charset=us-ascii
which is wrong and now png are displayed!

Which brings me to the good news. After I wrote to you I
received a message from  the TB developers  which emphasised
that, besides the information I have gave you, the main
point is the header, which should be 

  Content-type: multipart/related; boundary="=-=-="
 and the thunderbird developers insist that this is the 
 RFC 2387 standard.

Gnus actually generate  via the mml-generate-mime function
the header 
  Content-type: multipart/mixed; boundary="=-=-="
which is wrong.

I brought up the issue in the gnus mailing list and the
developers agreed that in the case of a html message with
png the Content-type should follow the RFC standard.

I checked this explicitly: your old code but with a different
mml-generate-mime function generates a message which is
correctly displayed in thunderbird and GMail and Ipod for
that manner. 

BTW I don't know how this issue, of the Content-type in the
header,  is treated in VM or Wanderlust.

Now the question is how to proceed:
I had the idea of introducing a new variable mml-mime-use-related and wrap it
into the mml-generate-mime code. Then org-mime-htmlize
should set this variable to t, and later a different
function should be added to the mail-send-hook setting the
variable to nil again.

Lars didn't like the idea and came up with a different
implementation. However I don't see how to use it easily. So
I include both solutions and let you decide which fits best
for org-mime-htmlize.
But as it is now you should undo your recent changes because
even with  the *new* mml-generate-mime function and your
*new* code the resulting mail is not displayed correctly in
TB.

I have now added lars and the ding mailing list to the CC.

Regards

Uwe 

My solution:
,----
| (defvar mml-mime-use-related t
| "*Variable to control whether to use `multipart/mixed' or `multipart/related'.")
| 
| (defun mml-generate-mime ()
|   "Generate a MIME message based on the current MML document."
|   (let ((cont (mml-parse))
| 		(mml-multipart-number mml-multipart-number))
|     (if (not cont)
| 		nil

| 		(if (and (consp (car cont))

| 			(mml-generate-mime-1 (car cont))
| 		  (if mml-mime-use-related

| 										  cont))

which wraps the html and images into a multipart/related type.

Why is this later structure illegal?  Are nested multi type parts not
allowed?  Also, it seems that everything I've tried works in gnus and in
most web user agents.  Is thunderbird simply a stickler for the letter
of the RFC law?

OK, I've just reverted my change, but I'm keeping the change of image
disposition to "inline".

OK.  Then I will assume that this issue is out of my hands and wait for
gnus to change its mime wrapping behavior upstream.

I do my best to provide reasonable implementations for these other two
mailers and assume that if anything goes wrong then someone will submit
a bug report.

While Lars' solution does look cleaner it is not clear to me how this
would be used from an external tool (such as org-mime) which does not
call `mml-generate-mime' explicitly, but rather relies on the normal
mailing process to handle these specifics.  Wouldn't it make the most
sense for the mailing process to inspect the email and set the
appropriate multipart type automatically.

I cannot answer this. However I rechecked everything and the

I own you an apology!  If I leave mml-generate-mime
untouched, that is I neither use my modification nor do I
use  use Lars new code, but  I use your *new* code then the
generated and sent message is displayed *correctly* in
thunderbird.

The resulting  message contains 

Content-type: multipart/alternative; boundary="=-=-="

Instead of 

Content-type: multipart/related; boundary="=-=-="

As it would in my case, but it seems that thunderbird is OK
with that.

The reason I wrote you earlier that your changes made things
worse was that I did make a mistake in my modification of
mml-generate-mime. I also thought I checked your code with
the old mml function but  for some reason the old version was
not used even after a restart.

Sorry for the trouble!

Uwe

Hi Uwe,

No problem at all.  I just reverted by reversion in git, so if I read
this email correctly everything should be working now in TB.  Please let
me know if this is not the case.
