Build failed with `MathJaxMacros`

[deepimpactmir]

I am using the GitHub Actions workflow that you have written out in this post. Tried using MathJax for better display of math equations but I'm running into an error when I add \Configure{MathJaxMacros}{header.tex} in the config.cfg file.

make4ht -c config.cfg -ua debug -d out ./IA_M/groups.tex "mathml,mathjax,fn-in"

An excerpt from the logs:

If you want to use LaTeX math with MathJax, remove the mathml option from your call to make4ht. It translates LaTeX commands to MathML, so your header.tex file wouldn't have any effect.

[deepimpactmir]

Mm. Unfortunately, I still have the issue after removing mathml option from the call

Here's the config.cfg

\Preamble{xhtml,mathjax,fn-in}
\Configure{MathJaxMacros}{header.tex}
\Css{body{max-width:50em; margin: 2em auto;}}
\Css{body{font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Bitstream Vera Serif", "Liberation Serif", Georgia, serif;}}
\Css{ span.verb, span.cmtt-10, span.cmtt-8{font-family:monospace,monospace;font-size:1em}}
\Css{.footnotes p + p{margin-top:0.3rem;line-height:1.5;margin-left:1rem;text-indent:-1rem;}}

It is possible that the make4ht-action used too old TeX Live. I've just rebuilt it, so it should get an update with the support for \Configure{MathJaxMacros}

[deepimpactmir]

I think it's still on TexLive 2022. An excerpt:

This is pdfTeX, Version 3.141592653-2.6-1.40.24 (TeX Live 2022/Debian) (preloaded format=latex)

Full run here.

[michal-h21]

Ah, it seems that the update created another package, I couldn't write to the original one. I had to resolve some permission issues, which hopefully should be fixed now.

[deepimpactmir]

Thanks! Seems like I'm getting a new error:

[michal-h21]

Ah, that's bad! It seems like make4ht doesn't use a correct version of it's libraries, so you get this error message about missing make_path function. I will need to investigate it more. In the meantime, you can try to use the TeX Live action, which includes make4ht too.

[deepimpactmir]

I will try that. Thanks!

[michal-h21]

BTW, I think make4ht-action now works too, at least in my tests it doesn't cause a fatal error. But the TeX Live action will be more up-to-date, so I think it is better to use that.

[deepimpactmir]

I see. Thanks for update! :). I'll close the issue.
