Hello everybody,
I have a problem with HTML export and Mathjax.
On the Mathjax site it is written that:"
There are two ways to access MathJax: the easiest way is to use the copy
of MathJax available from our distributed network service at
cdn.mathjax.org,
[and some lines below: "We recommend using the CDN service"]
but you can also download and install a copy of MathJax on your own server,
or for use locally on your own hard disk (with no need for network access)."
So I went for the CDN service.
Incidentally, if it worked, we could drop the
http://orgmode.org/mathjax/MathJax.js support.
In the section "Putting mathematics in a web page" of the
[[http://www.mathjax.org/docs/1.1/start.html#putting-mathematics-in-a-web-page][Mathjax documentation]]
it is written that: "To put mathematics in your web page, you can use
either TeX and LaTeX notation or MathML notation or both within the
same page;"
and this is done putting two scripts in the html file[1]
"The default math delimiters are $$...$$ and \[...\] for displayed
mathematics, and \(...\) for in-line mathematics."
Now if I try to export to HTML the following file
--------------------------------------
-*- mode: org -*-

---------------------------------------------------------------------------------------------
the math snippets are always "converted" in HTML format e.g.: α = \frac{1}{L<sub>0</sub>}
:-(
unless they're inside the #+BEGIN_HTML block.
Is there another way to tell the HTML exporter to copy verbatim the lines inside the
math delimiters?
cheers,
Giovanni

Do I understand correctly that this is your problem? (Not very clear
from your long example, which starts with the CDN service.)
If so, I can't reproduce it. Your
$$
\alpha = \frac{1}{L_{0}} \left( \frac{L_2-L_1}{T_2-T_1} \right)
= \frac{1}{L_0}\frac{\Delta L}{\Delta T}
$$
exports verbatim for me, and is correctly formatted.
Yours,
Christian

I tried. Yes and no.
Yes, You're right. It is exported correctly and correctly formatted
if you export only *this* subheading. The subheading "** $$".
But, if you export the whole subtree, from the
"* mathjax test " heading, the equation is
"converted" in HTML format e.g.:α = \frac{1}{L<sub>0</sub>}

Ah, I see.
The problem is that the "$$" in the subheading is interpreted as an
unclosed math snippet. (Interesting that it's still exported as a
heading.) After that, math closes when it should open.
Try closing the subheading: "* $$ $$" and exporting again.
Getting "$$" as a subheading is not quite straightforward, but the
following will work. Create a user-defined dollar-sign entity (org
doesn't have one by default):
(setq org-entities-user
'(("dollar" "\\$" nil "$" "$" "$" "$")))
Now "* \dollar\dollar" should work.
Yours,
Christian

Hi, Christian,
thank you for cheching again.... well *MY* mistake
was setting the option:
:EXPORT_OPTIONS: H:3 num:nil toc:nil \n:t @:t ::t |:t ^:t f:nil *:t
tags:nil TeX:t LaTeX:nil
^^^^^^
Consequently the LaTeX fragments are "converted" in HTML format e.g.:
u(α) = δα = {\left(
\left[\frac{-(Δ L+c)}{L<sub>0</sub>⋅ [...]
Why not, since I set this option? :-(
Sorry for the noise and thank you again for your time,
Giovanni
