HTML export for math markup

HTML export for math markup

[Lawrence Bottorff]

[-- Attachment #1: Type: text/plain, Size: 665 bytes --]

I've got an org file with Latex math markup, e.g. $x_2/y^3$. When I export
this to HTML, it produces png files for each markup and puts them in a
subfolder ltximg. Is there any way to skip this translating to pictures and
just use MathJax directly. I've seen this
<http://orgmode.org/manual/Math-formatting-in-HTML-export.html>, but my
setup seems to be defaulted to png picture production, not direct MathJax
rendering via "
http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML. I
understand that what's happening is this
<http://orgmode.org/worg/org-tutorials/org-latex-preview.html>, but that's
not MathJax. What am I doing (thinking) wrong?

Have you tried exporting with a minimal init file and none of your customizations?

The default behavior with a plain vanilla installation is, indeed, to use
png files and create the ltximg subdirectory. It's not a huge problem, but
I'd prefer it not doing that; instead, using MathJax. Anyone know how to
switch this behavior?

No, the default with a plain vanilla install is MathJax. In your minimal init environment,
what is the value of org-html-with-latex? What about org-export-with-latex? Both of these
should be t by default.

If they are, I would edebug org-html-format-latex, run the export and,
when it stops at org-html-format-latex, look at its arguments: the
second argument is the processing-type and it *should* be mathjax.

MathJax should be the default behaviour. See `org-html-with-latex'.

This is the entirety of my header section. I'm sure there are redundancies
etc. But again, the clean vanilla of Emacs 25.1.1 and org-mode 9.0.2 is
defaulting to producing png's.

org-html-with-latex is t and org-export-with-latex is also t. I don't have
a org-html-format-latex, or at least nothing comes up with C-h
v org-html-format-latex. Also, how does edebug work as you, Nick, described?

Yes, I tested all my header lines and found that was the 'offender." It got
there on someone's suggestion it was needed for proper TikZ. Or was it
bibtex? Or does a ton of pngs come if you choose Latex preview? No time for
further investigation. Confusion will be my epitaph. . . .

I think, IIUC, the tex: option is for inline LaTeX and maybe (maybe not)
exported LaTeX.  If you want to use mathjax for this, then tikz et
al. need to be done differently, e.g. using src blocks with a :file
output.
