Dear list,
I have a couple of gripes about LaTeX handling in ODT export when one
needs MathML conversion, and therefore a couple of questions:
The first one is possibly a gripe with the ox-pandoc exporters. The doc
(info manual) states :
"Add this line to the Org file. This option is activated on a per-file
basis.
#+OPTIONS: LaTeX:t"
It seems that this option is *NOT* handled by the ox-pandoc exporters :
when using one of these, the text "LaTeX:t" appears at the top of the
output.
Hence my first question : what should be responsible for handling this
option : org mode or ox-pandoc ?
The second one is that I can't get org to acknowledge the configuration
of org-latex-to-mathml-convert-command. A bit of peeking int the source
leads to this function, responsible for testing it :
=======================================================================
(defun org-format-latex-mathml-available-p ()
"Return t if `org-latex-to-mathml-convert-command' is usable."
(save-match-data
(when (and (boundp 'org-latex-to-mathml-convert-command)
org-latex-to-mathml-convert-command)
(let ((executable (car (split-string
org-latex-to-mathml-convert-command))))
(when (executable-find executable)
(if (string-match
"%j" org-latex-to-mathml-convert-command)
(file-readable-p org-latex-to-mathml-jar-file)
t))))))
=======================================================================
As written, I can't see how one can use latexmlmath WITHOUT having ALSO
the MathToWeb jar file somewhere : the test for it is systematic ;
therefore, it fails if the jarfile isn't configured/available.
The value of executable should be tested, and the test for the jarfile
should be done *only* if executable is "java" (or, better, belongs to a
list of "reasonable" java executables or scripts...).
So my second question is : what do you think ?
HTH,

Sorry for the noise : the bugs do exist, but my previous analysis was
false (one paren too much).
More data points :
* I installed also MathToWeb, and configured it in emacs
(via file-local-variables), with the same problematic result.
* The error message "LaTeX to MathML converter not configured"
appears exactly twice in org.el:
+ In org-format-latex
+ In org-create-math-formula
* In both cases, the call has the form :
=================================================================
(unless (org-format-latex-mathml-available-p)
(user-error "LaTeX to MathML converter not configured")))
=================================================================
* When evaluated from M-: (org-format-latex-mathml-available-p)
returns t (as it should...).
* I have been so far unable to trace the origin of the faulty
evaluations. I'll probably have to run an uncompiled org for this,
and I don't (yet) know how to do that.
Interim hypothesis : the relevant variables
(org-latex-to-mathml-jar-file and org-latex-to-mathml-convert-command)
may be inadvertently shadowed somewhere upstream in the call tree.
I'm afraid to be a bit out of my depth here...
Suggestions ?
