Question about the math mode table exporting for latex and html

Question about the math mode table exporting for latex and html

[bsun]

hello list,

Here is the example.

------------------------------------------------------------------------
#+ATTR_LATEX: :mode math :environment pmatrix :math-prefix \mathbf{H}=
| \vdots | 0 | \vdots |
| \vdots | H | \vdots |
| \vdots | 0 | \vdots |
------------------------------------------------------------------------

These lines generate perfect latex code. But the html exporter omits
the #+attr_latex line (which is correct), and produces a plain text
table.

The question is, is it possible to export the math mode table as latex
code in html exporting? Maybe there is some option like
"#+attr_html: :mode latex"?

Thanks.

Regards,
Bing

I have noticed this "bug" as well, but forgot to report it since it
isn't really a bug.

No.

AFAIK, mathjax supports amsmath matrices, e.g. the third example here¹ .
Thus, we'd really just want to insert the output of org-latex-table in
the html-file.

Perhaps something like the following would be OK?  Nicholas?

#+ATTR_HTML: :mode latex
#+ATTR_LATEX: :mode math :environment pmatrix :math-prefix \mathbf{H}=
| \vdots | 0 | \vdots |
| \vdots | H | \vdots |
| \vdots | 0 | \vdots |

This would tell ox-html.el to transcode the table via ox-latex-tabel
and feed the string via org-html-format-latex (assuming latex-frag is
a string).  Of course ox-html could also check out ATTR_LATEX but this
would lead to a spurious solution since LaTeX ≠ HTML IMO.

Alternatively, you'd have to use one the following hooks described in
ox.html (since filters would work on a transcoded elements).

;; Eventually, two hooks (`org-export-before-processing-hook' and
;; `org-export-before-parsing-hook') are run at the beginning of the
;; export process and just before parsing to allow for heavy structure
;; modifications.

Nicholas, if you want I can look into this.

puzzling org-mime-htmlize

[Joseph Vidal-Rosset]

Hello the list,

Back to gnus in order to improve my life in emacs, I meet a very strange
problem with  org-mime-htmlize. The  more surprising  fact is  that this
problem does  not appear  on my  laptop (running  with GNU  Linux Debian
testing) but only with my PC (running also with a Crunchbang + Debian
wheezy upgraded to  testing). Therefore I have imported  my .gnus.el and
my  init.el from  my laptop  to my  pc, but  very strangely  the problem
persists ! 

It is the same settings, the  same O.S. , even the same org-mime.el
and it works on laptop, not on my pc. 

Here is the error message: 

Creating LaTeX Image...
Failed to create dvi file from /tmp/orgtex11506Npy.tex
Auto-saving...


I do not know what to do, because I can't guess where the problem is. 

I send this message with Gnus to say you that your help is very welcome. 

Jo.

Many thanks Nick. I did not think about  it.

I have no opinion on this one. Nicolas, if you think this is the
correct approach syntactically, then it works for me.

Fwd: puzzling org-mime-htmlize

[-- Attachment #1: Type: text/plain, Size: 1599 bytes --]

Dear Eric (cc. the list),

I apologize to insist with this problem that I meet with org-mime-htmize in
the gnus on my PC.

On my laptop, with the same OS and I believe the same configuration, it
runs perfectly. Here I meet always this sort of message:

Creating LaTeX Image...
Failed to create dvi file from /tmp/orgtex11506Npy.tex
Auto-saving...


I have tried to run latex /tmp/orgtex11506Npy.tex - as adviced Nick -  and
the dvi file was created.

I  understand neither what happens nor how I can fix this problem. Do you
see  an possible explanation ?

Best wishes,

Jo.

Not enough information: post the procedure you follow and a minimal org

Hi Nick,  I apolgize, it's difficult for me to be more complete that I was.
It is not org, but gnus with org. M-x  org-mime-htmlize creates the html
email, but fails to make access to /temp/image.png . That's it.

You are kidding, right? Here, let me start and maybe you can see where
I'm going.

In gnus, I was reading your message and did "f" to follow up. I then
entered this org fragment:

--8<---------------cut here---------------start------------->8---
* Org fragment for org-mime-htmlize to chew on.

Does this work?
--8<---------------cut here---------------end--------------->8---

I then called org-mime-htmlize. That added the html part and I then sent
it with C-c C-c. How hard is that?

BTW, just in case I made you feel bad: I've been ranting about things
like this for years, e.g.

[[http://article.gmane.org/gmane.emacs.orgmode/32130/match=ask+questions]]

You are not the first, and you are not going to be the last: asking good
questions is learned, so there is hope :-)

BTW, I think the reference to ESR's "smart questions" paper has been
added somewhere in Worg, but a few minutes search did not uncover it.
Anybody know where it is?

Also btw: I almost never send HTML mail - this is a very special case.

Nick

There is a link to it on the front page.  Second to last line in the
"Documentation and Literature" section.

Of course, it may be linked elsewhere too.

Hi Nick,

No, I did not kidding, unfortunately.

I'm replying with gmail, and I am afraid I will give up the project to use
Gnus. From yesterday evening, suddenly I have on my two computers an error
message with gnus:

'smtp-server'  not defined.

I've of course tried to solve this new problem, with help of archives of
mailing lists given by Google, all my tentative are at the moment
unsuccessful...

It's both boring and irritating.

The least that I expect from an email client is to work correctly. Gnus
worked, for sending and receiving emails, and suddenly without clear
reason, it does not work no more... It is not stable because I have not
changed .gnus.el ...

I am sorry to have bothered you for nothing, but I am tired and
disappointed by emailing via emacs. I loose more time in trying to
configure gnus for my gmail account than in reading and replying to my
emails...

I will going to try to improve my use of org-mode, but Gnus is not made for
me...

Best wishes,

Jo.

If you haven't changed anything in your Gnus configuration and if
you are still using the exact same setup that used to be working,
it's hardly Gnus fault... maybe gmail changed something?

Anyway, just to give you some more encouragement: it's really worth
insisting.

Hi Bastien,

It was FLIM's fault. The bug is here:

My gnus works now. But I'm still using Gmail at the moment.

Hi again Nick, 

What is  easy for you in  one domain can  be hard for other  people, and
conversely for other domains.

I saw your other message where FLIM (whatever that is) is identified as
the culprit. One piece of advice: do not install random software
packages without thorough testing. The best way to test is with a
minimal .emacs that just loads the package under test, start a new emacs
with it (emacs -q -l /path/to/min.emacs) and test the heck out of it
before admitting it into the set of trusted packages that you load in
your everyday emacs session. I routinely have three emacs sessions
going: my everyday emacs, a separate one that I use as an IRC client
(running erc) and a third short-lived one for tests.  My everyday emacs
runs for weeks at a time; the irc emacs gets restarted every time I
switch networks (I wish erc would maintain the connections, but they get
dropped); the short-lived one(s) lasts from a few minutes to a few
hours.

... but you installed FLIM, right? That installed its own smtpmail.el
which apparently you picked up in preference to the one that came with
emacs. This is a fairly common mistake.

Bastien's channeling of Beckett was the perfect answer here, but as
usual I have a few more comments :-)

Gnus is indeed peculiar: I switched to it about 8 months ago and I'm
still not quite comfortable with it. However, although I occasionally
use gmail and thunderbird, I'll take an emacs-based mail client over
them every time: I used mh-e for many years and switched to gnus only
because I wanted an imap server at home - afaik, mh-e (and nmh underneath
it) just did not support that use case.

As a general principle however, you need to decouple your attempts to
use gnus from your attempts to use org. I recently advised somebody not
to use all the blades of the org swiss-army knife at the same time.
Trying to do that in combination with gnus is turning the knife into a
chainsaw (swiss-army chainsaw anyone?)

Do them one at a time: it may seem slow and inefficient to you now, but
it is much more efficient than the alternative - damhikt...

Dear Nick and dear all,

Sorry for my previous message. I have had to cut the html code in order to
succed to sent my message with Gnus. The result is not beautiful. But I
hope that it will help to understand the problem.

Nick, many thanks for your patience with me and for all your efforts with
the community.

Best wishes

Exactly. FWIW, it works fine for me, so it's not an org-mime (or oher
org) problem.  It is probably a problem in your setup: it seems that you
cannot generate latex fragment images.

Create a file, foo.org say, and insert the above content:

--8<---------------cut here---------------start------------->8---
* This title

should work

But the following formula 

$$ \neg \neg A \nvdash_{i} A $$

should not. 
--8<---------------cut here---------------end--------------->8---

Split the window and visit the *Messages* buffer in one of the
windows. Then do C-c C-x C-l in the foo.org window (or what amounts to
the same thing, M-x org-preview-latex-fragment). Does it fail? What does
the *Messages* buffer say?

Yes, I agree,  it is very probably a  problem in the setup of  my PC, in

C-c C-x C-l works fine: I see the equation image in the buffer. 

Here is the result of Messages buffer:

Loading reftex...done
Mark set
Creating images for entry...1
Process completed.
Creating images for entry...done.  Use `C-c C-c' to remove images.
byte-code: End of buffer

Unfortunately, the same problem persists in boring me. I have even tried an
"aptitude reinstall emacs24", nothing has changed.

I got this result with a formula:

Where you'll can see the image of Peirce Law, but I cannot send the message
via Gnus because the message error:

I do not understand.

I send this message from Gmail  (Gmail-Tex displays the image), because I
am unable to find our thread in the Group of this List  in Gnus, but it is
another problem....

Yes, you are right Bastien. 

Good news: I have finally the explanation  of the "bug". Here is, and it
could be a lesson for all Debian users. 

All the problems that I had theses times came from the same cause: I had
decided to  install some  very useful packages  not via  Debian aptitude
system, but  via direct sources  in /usr/local/  just in order  to avoid
boring and long re-installation of texlive-full for example. 

But it has certainly created some  confusion, probably my .bashrc is not
correctly written, I do not know. 

This morning I have removed and purge all what could be in relation with
latex and re-installed bibtex2html, texlive, and so on. And now it works
fine. 

Here is Peirce formula: 


$$ ((A \to B) \to A) \to A $$


End of this thread. I am going to  open another one about Gnus - Org and
$ \LaTeX $

Best wishes,

Jo.

I have attached a rough proof-of-concept that will export the above
table correctly with mathjax.  But I guess it will also have to handle
it correctly in the case of static png images.

I'm not sure how to handle captions.  I guess the most natural way is
to let org-latex-table handle is.  Let me know if something like this
is OK in which case I can polish it up and add documentation.

Thank you. 

I agree that PNG handling is required. I think you need to call
`org-html-format-latex' around the generated table. You get
PROCESSING-TYPE with (plist-get info :with-latex). See
`org-html-latex-environment' for gory details.

A few comments follow.

`org-export-read-attribute' returns a plist, so it should be:

  (plist-get (org-export-read-attribute :attr_html table) :mode)

But, if there is only one mode to implement, wouldn't it be more
straightforward to call it ":latex t" instead?

> +       (cond
> +	((member-ignore-case "latex" mode)

Using `plist-get', MODE will be a string, as expected. You can then use
`compare-strings'. If you use ":latex t" syntax, you can have instead:

  (if (plist-get (org-export-read-attribute :attr_html table) :latex)
      (org-html-table--as-latex ...)
    (let* (...)))

You will have a LaTeX table with HTML markup in its cells. Also, calling
`org-latex-table' directly is a bit fragile. Use:

  (org-export-with-backend table 'latex info)

CONTENTS will be computed again with `latex' export back-end.
