Latex command compilation in HTML export

Latex command compilation in HTML export

[Sylvain Salvati]

Dear Orgmode list,

during the HTML export of an org document, I would like to compile its
latex fragments to SVG using the sequence of commands

lualatex --shell-escape --interaction=nonstopmode --output-format=dvi --output-directory=%o %b
dvisvgm %b

but I have not been able to find out where I could do this
customization.

Any help is wellcome,

best,

Sylvain.

I am not sure this is possible although maybe it should be...  The info
pages at

    (org) LaTeX fragments

seem to imply rather hard-coded methods and the only variable that seems
relevant is this one:

,----[ C-h v org-html-with-latex RET ]
| org-html-with-latex is a variable defined in ‘ox-html.el’.
| Its value is ‘imagemagick’
| Original value was t
| 
| Documentation:
| Non-nil means process LaTeX math snippets.
| 
| When set, the exporter will process LaTeX environments and
| fragments.
| 
| This option can also be set with the +OPTIONS line,
| e.g. "tex:mathjax".  Allowed values are:
| 
| nil            Ignore math snippets.
| ‘verbatim’     Keep everything in verbatim
| ‘dvipng’       Process the LaTeX fragments to images.  This will also
|                include processing of non-math environments.
| ‘imagemagick’  Convert the LaTeX fragments to pdf files and use
|                imagemagick to convert pdf files to png files.
| ‘mathjax’      Do MathJax preprocessing and arrange for MathJax.js to
|                be loaded.
| t              Synonym for ‘mathjax’.
| 
| You can customize this variable.
| 
| This variable was introduced, or its default value was changed, in
| version 24.4 of Emacs.

You could maybe export to verbatim and then apply an export filter to
do what you want.  Non-trivial, or at least beyond my capabilities ;-)
