Hi Michal, I started using make4ht again after a long time, but I ran into a problem I had never encountered before. I am sending you a minimal example that compiles perfectly with lualatex, but fails with make4ht.

The versions of lualatex and TexLive are as follows:

$> lualatex --v This is LuaHBTeX, Version 1.18.0 (TeX Live 2025/dev/Debian)

$> texliveonfly --v 1.2

Thanks for your attention.

\sigma x

\[\frac{f_{i;j}}{f_{i;}.}=\frac{f._{;j}}{N} \sand 
  \frac{f_{i;j}}{f._{;j}}=\frac{f_{i;}.}{N} \ssRarrow 
  f_{i;j}=\frac{f_{i;}. \times f._{;j}}{N}\]

\[\forall i,j\colon\; c_{ij}=0 
\ssRarrow\sum_{i=1}^{i=h}\sum_{j=1}^{j=k}\frac{c_{ij}^2}{f_{ ij}}=0\]

\bigskip
These works around work correctly.

Hi Danielle, I only get the error with this command: \sigma x, used outside the math mode on line 23. I think it is an error, but you are right that LuaLaTeX compiles it without errors. When I compile it with the -l option of make4ht, which requires LuaLaTeX backend, it compiles without error too.

I get the error only in the default PDFLaTeX mode. And I get an error also with PDFLaTeX, so the behavior of make4ht seems to be the same.

Compiling with:

make4ht macro.tex -c ml_make4ht -l -u -s -d ./html/mathjax2 "mathjax, 2, sec-filename, fn-in, blind"

Ah, I can see it now. Try to add these definitions to your config file:

\def\quad{\HCode{<span class="quad"></span>}}
\Css{.quad{min-width: 2rem;display: inline-block;}}
\def\qquad{\HCode{<span class="qquad"></span>}}
\Css{.qquad{min-width: 3rem;display: inline-block;}}
\def\sigma{\HCode{<i>&sigma;</i>}}

This will have an effect on these commands used outside of the math mode.

But I get: \text{Teorema di Pitagora: } \qquada^2 = b^2 + c^2 instead of: \text{Teorema di Pitagora: } \qquad a^2 = b^2 + c^2

michal-h21 commented 1 week ago

Ah, you shouldn't get that with the current TeX4ht code, but there was a bug that could lead to this. I fixed it a month ago.

danielezambelli commented 1 week ago

How can I install the correct version?

michal-h21 commented 1 week ago

If you use TeX Live, tlmgr update --all should suffice. The correct version of mathjax-latex-4ht.4ht (you can find the location using kpsewhich mathjax-latex-4ht.4ht) should be:

  % mathjax-latex-4ht.4ht (2024-09-27-09:25), generated from tex4ht-mathjax.tex
danielezambelli commented 1 week ago

Unfortunately, both sudo tlmgr update --all and tlmgr update --all

give as a result:

(running on Debian, switching to user mode!) (see /usr/share/doc/texlive-base/README.tlmgr-on-Debian.md) TLPDB: not a directory, not loading: /root/texmf tlmgr: user mode not initialized, please read the documentation!

And I couldn't get out of it from here.

I searched at https://github.com/michal-h21/make4ht/tree/master for the file mathjax-latex-4ht.4ht, to replace it directly in the dir tex4ht but couldn't find it.

Can you give me any hints?

Thanks.

michal-h21 commented 1 week ago

Ah, so you use TL in your distro, so you cannot use tlmgr directly. I think Debian is a bit slower in picking up updates, but I hope they will do it eventually.

In the meantime, here is the up-to-date mathjax-latex-4ht.4ht file:

Thanks for your expertise and helpfulness!

michal-h21 commented 6 days ago

You are welcome! I hope TL in Debian will get the fixed version soon.
