[tex4ht] exerquiz problems

[Tomas Davidek]

Dear all,

   I have made few more tests with exerquiz package. The LaTeX source uses exerquiz package from the AcroTeX education bundle (https://ctan.org/pkg/acrotex), the latest version as available in CTAN is used. The LaTeX source file perfectly compiles with pdflatex (I am using the TeXLive distribution v. 2020 on Debian testing). Now when running make4ht on that, I noticed several interesting features:

* make4ht -c split.cfg -u exerquiz_ex.tex



* make4ht -c split.cfg -u exerquiz_ex.tex "2"

Attempting to split the Web pages on the per-chapter basis results in


[FATAL]   make4ht-lib: Fatal error. Command htlatex returned exit code 1







Thanks a lot for any hint.

Best regards,

                         Tomas

Although there are many errors from htlatex, the code compiles and the resulting Web page contains everything. Nevertheless, most of the error messages come from /usr/share/texlive/texmf-dist/tex/generic/tex4ht/exerquiz.4ht [ERROR]   htlatex: ?    116      TeX capacity exceeded, sorry [input stack size=5000]. I suspected that the problem is  due to exerquiz package. Unfortunately yes, the problem can be removed by commenting out _all_ exerquiz stuff, then all error messages disappear. I am afraid that exerquiz.4ht filter is old (as Michal already pointed out) and needs to be updated. I have no idea how difficult it is, please can someone have a look? Attached is a tarball containing the LaTeX source file used for these tests, the configuration file and all files required by the exerquiz package.
