Hello,
I made several tests with tex4ht. The tool nicely converts most of
the objects/environments, but I noticed two problems:
1. split environment
I use that for typesetting long formulas, for instance
This is my very long formula
\begin{displaymath}
\begin{split}
\tau(\eta^0) & = \frac{\hbar}{\Gamma(\eta^0)} =
\frac{\hbar c}{c \Gamma(\eta^0)} =
\frac{0{,}197~\gev\cdot\mathrm{fm}}{3\cdot
10^{8}~\mathrm{m}\cdot\mathrm{s}^{-1}\times 1{,}30~\mathrm{keV}}
= \\
& = \frac{0{,}197\cdot 10^{-15}~\gev\cdot\mathrm{m}}{3\cdot
10^{8}~\mathrm{m}\cdot\mathrm{s}^{-1}\times 1{,}30\cdot
10^{-6}~\mathrm{GeV} = % \nonumber\\
0{,}0505\cdot 10^{-17}~\mathrm{s} = 5{,}05\cdot
10^{-19}~\mathrm{s} % \nonumber
\end{split}
\end{displaymath}
This works perfectly in pdflatex, but when running htlatex, I get the
following error message:
=======
! Package amsmath Error: \begin{split} won't work here.
See the amsmath package documentation for explanation.
Type H <return> for immediate help.
...
l.79 \end{split}
?
! Emergency stop.
...
l.79 \end{split}
============
Can someone please help me in figuring out what's wrong and how to avoid
that?
2. I am using exerquiz package of AcroTeX education bundle
(https://ctan.org/pkg/acrotex) which easily allows to typeset individual
exercises and display/hide solutions. Unfortunately, it does not seem to
work with tex4ht, when running htlatex, there is a conflict with one of
the include file (epdfmark.def, part of this CTAN package)
====================
) (/usr/share/texlive/texmf-dist/tex/latex/hyperref/htex4ht.def)
(./insdljs.sty
) (./eforms.sty (./epdfmark.def))
exerquiz: * Using dvipsone/dvips option *
! LaTeX Error: Command \theHquizno undefined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.297 \renewcommand\theHquizno
{\curr@quiz.\theeqquestionnoi.\alph{quizno}}
?
! Emergency stop.
...
l.297 \renewcommand\theHquizno
{\curr@quiz.\theeqquestionnoi.\alph{quizno}}
==========
I understand that processing some environments that are not part of
standard TeXLive distribution might be problematic. Nevertheless, is
there a way to tell htlatex to e.g. to deal with them as images? Or any
other way?
Thanks a lot for any hint
best regards,
Tomas
