jgm / pandoc-tex2svg Goto Github PK

I am running pandoc 2.1.1 and have installed mathjax-node and the pandoc-tex2svg filter.

I have also installed mathjax-node-cli and have tex2svg available from my Path. It is located here:

/c/Users/~/AppData/Roaming/npm/tex2svg

When running the pandoc command

pandoc math-samples.md --filter pandoc-tex2svg -s -t html5 -o math-samples2.html

I get the following error:

The tex2svg program was not found in the path.
Install MathJax-node (https://github.com/mathjax/MathJax-node)
and ensure that tex2svg is in your path.
Error running filter pandoc-tex2svg:
Filter returned error status 1

Hello!

A search does not return anything: see here. Is there a workaround?

EDIT: It seems that a tex2svg executable is available here, and it seems to work. :)

Thank you for the nice script!

Markdown:

\begin{equation}
E = mc^2
\end{equation}

\begin{equation}
E = pc
\end{equation}

Command:

pandoc --mathjax -F pandoc-tex2svg

The resultant HTML is untouched by MathJax-node.

And by the way, the same test can be used to test AMS equation numbering. Because it is rendered by mj-single.js, I expect it not able to increment the numbering. I'm not sure what's the solution though (besides using mj-page.js which is supposed to work on HTML5 output. But obviously the one need this most is ePub output. I'm now thinking if it is possible to throw in the whole HTML file before combining it to ePub. However, I don't know the pandoc ePub build process so I don't know if it is possible.) I should have thought about this point before suggesting passing each equation to tex2svg rather than page2svg. I thought this is more robust, but now we lost AMS-numbering... Sorry!

I tried running it on a large file (book-size), and there's a lot of error message, a sample is like this:

Probably it is some syntax it is complaining about (I also configure the MathJax manually), but unlike MathJax that will show the wrong syntax in red, MathJax-node will just choke and complain. So it would be helpful by showing some error message. Perhaps if there's an error, print the Math sent into MathJax-node?
