Is this a known bug? If not, I can enter official report on it.
When using \TocAt with \PauseCutAt, tex4ht gives error. Please see the following MWE ================== \documentclass[11pt,notitlepage]{book} \begin{document} \ifdefined\HCode \TocAt{chapter,section} %show subsection only in sections TOC \TocAt{section,subsection} %show subsection only in sections TOC \fi \ifdefined\HCode \PauseCutAt{section} \fi \chapter{Introduction} chapter \section{test} stuff \subsection{more stuff} stuff \end{document} =================================== Compiled using make4ht -ulm default -a debug t.tex "htm,3,notoc*,p-width" ./t.aux) (/usr/local/texlive/2019/texmf-dist/tex/latex/base/ts1cmr.fd) [1] [2] Chapter 1. (./t.4ct) (/usr/local/texlive/2019/texmf-dist/tex/latex/lm/ot1lmtt.fd) (./t.4ct ) (./t.4ct ! Missing number, treated as zero. <to be read again> \TitleCount l.3 ...k\endcsname{2}{x2-20001.1}{QQ2-2-2}{test}}{3} \relax ? 2 ways to make the error goes away: ====================================== A) use split level 2 instead of 3 (but I want to use 3). So this works make4ht -ulm default -a debug t.tex "htm,2,notoc*,p-width" B) use split 3, but comment out the line %\TocAt{section,subsection} In the above tex file. (But I want to have toc at section level). Is this known? And why it happens and is there a workaround other than these two above? TL 2019 on Linux. Thnaks --Nasser
