I'm confused! Having never used this, I gave it a try since it's not
too involved. I'm completely at a loss.
- Downloaded jsMath-3.6e and the image fonts
- Unzipped both, creating a jsMath-3.6e dir (main js) and a jsMath dir (fonts)
- Moved jsMath/fonts to jsMath-3.6e/fonts
- Tried the sample from Worg you posted
(http://orgmode.org/worg/org-tutorials/org-jsmath.html)
- Edited jsMath-3.6e/easy/load.js to contain this revised loadFiles line:
#+begin_src load.js
loadFiles: ["extensions/AMSmath.js","extensions/AMSsymbols.js",
"extensions/autobold.js", "extensions/eqn-number.js"],
#+end_src
Used this file to test:
#+begin_src Org
#+STYLE: <SCRIPT SRC="../jsMath/easy/load.js"></SCRIPT>
\[
\label{a_label}
x=2*y
\]
Bla bla bla from equation \(\ref{a_label}\)
#+end_src
Exported to html, and get the undefined sequence error. I *also* don't
get a numbered equation, which jsMath says I should get:
- http://www.math.union.edu/~dpvc/jsmath/authors/eqn-number.html
Looking at the raw html, I saw no mention of jsMath anywhere, only
MathJax. Then I wondered if #+STYLE is even the correct syntax for Org
8.0 anymore, partly due to this recent post and the fact that I've
migrated to my response for css:
- http://lists.gnu.org/archive/html/emacs-orgmode/2014-06/msg00095.html
So, I replaced #+style with #+html_head, and at least I get this line now:
<SCRIPT SRC="/home/jwhendy/Downloads/jsMath-3.6e/easy/load.js"></SCRIPT>
The equation renders, but I get no equation number, which tells me
something's probably not right with the \label{} command; perhaps this
is the reason or the \ref{} error (no matching label, and thus no
ability to reference it)?
**Edit**: if I delete the auto-inserted MathJax script stuff from my
.html file, the equation does not render, either. I think it only
renders because Orgmode includes some MathJax functionality; it's not
really working with jsMath, hence it's not accessing the functionality
to label and refer to equations.
Oddly, I *don't* get rendered math with the test/index.html file as
described here:
- http://www.math.union.edu/~dpvc/jsmath/authors/installation.html
I get raw TeX and a red warning that jsMath is not functioning properly.
Sorry I can't be of more help. Mainly wanted to write and confirm that
this isn't working correctly for me, either.
