Hi,
I have exported a jupyter notebook to markdown. The problem is that has encoded its generated latex as html like this example (which I think is mathjax).
> <html><script type="math/tex; mode=display">\newcommand{\Bold}[1]{\mathbf{#1}}\left\{\begin{array}{lcl} r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = & \arctan\left(\frac{y}{x}\right) \end{array}\right.</script></html>
I really want it to be something like
> $$\begin{array}{lcl} r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = & \arctan\left(\frac{y}{x}\right) \end{array}$$
Is there an easy way of doing this and / or has someone written a filter to do something like this? I’d rather avoid having to write a filter myself if possible. NB I do *not* want latex as I need to convert this into something that WordPress likes. In this example, it would be something like
> $latex \begin{array}{lcl} r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = & \arctan\left(\frac{y}{x}\right) \end{array}$
Many thanks,
Dominic Steinitz

Hi Dominic.
How did you export your Jupyter notebook to Markdown?
I just tried it both via the menu ("File" -> "Download as" ->
"Markdown") and via nbconvert (python3 -m nbconvert --to markdown
mynotebook.ipynb). In both cases, the LaTeX math was unchanged, no
HTML stuff was added.
I've created a pandoc filter to convert "raw LaTeX" nodes to "math"
nodes, this might give some pointers how to add "$latex ... $":
https://github.com/spatialaudio/nbsphinx/blob/18a4a32bd98e8bfa92612f9ab9d5fce212eff205/nbsphinx.py#L713
BTW, from a LaTeX point of view it doesn't make sense to put dollar
signs around a math environment, this would make more sense (just
remove the dollar signs):
\begin{array}{lcl}
r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = & \arctan\left(\frac{y}{x}\right)
\end{array}
... and it is actually supported by Jupyter (and by pandoc).
You could use nbconvert to convert your notebooks to Markdown, and
then run pandoc on them with a custom filter that adds the "$latex ...
$".
cheers,
Matthias

The LaTeX I write myself is fine but the output from the notebook is the
problem. I am using sagemath to do symbolic manipulations. Hmmm maybe I can
coax jupyter / sagemath into producing latex. Let me try.

Ok I am making progress. In my .ipynb file I now have
print(latex(cartesianToPolar.display()))
and after processing with
jupyter-nbconvert --to markdown Mercator.ipynb
I can see
\left\{\begin{array}{lcl} r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = & \
arctan\left(\frac{y}{x}\right) \end{array}\right.
I have written a filter as suggested

But no joy :( I still have
\left\{\begin{array}{lcl} r & = & \sqrt{x^{2} + y^{2}} \\ \theta & = &
\arctan\left(\frac{y}{x}\right)\end{array}\right.
I am not sure what I should pattern match on.
Thanks, Dominic.

This has some unnecessary steps. Try the simpler:
#!/usr/bin/env runhaskell
import Text.Pandoc.JSON
wordpressify :: Inline -> Inline
wordpressify (Math x y) = Math x ("LaTeX " ++ y)
wordpressify x = x
main :: IO ()
main = toJSONFilter wordpressify
toJSONFilter does all the work of lifting wordpressify
into a transformation Pandoc -> Pandoc -- and there's
no need to involve IO.
Try your filter with some simple math first:
$x=y$
and see if it works. Then see if it works for your
intended application.
