I found interesting problem. In my tex4ht configuration file, I have the line that says
\catcode`\:=11 \catcode`\@=11
It have been there forever. I think it was to solve a problem from this answer. Or I might got it from another place. I do not remember now. It never caused a problem, except now.
But I just found out that htlatex fails on one tikz picture. Here is the MWE
\documentclass[12pt]{article}
\ifdefined\HCode
\def\pgfsysdriver{pgfsys-tex4ht.def}
\fi
\usepackage{tikz}
\usetikzlibrary{arrows,calc,decorations.markings,math}
\begin{document}
\begin{tikzpicture}
\draw let \n1={2} in (0,0) -- (30:\n1);
\end{tikzpicture}
\end{document}
Only on the above example, with the polar coordinate. If I use normal coordinates, no error:
\begin{tikzpicture}
\draw let \n1={2} in (0,0) -- (1,\n1);
\end{tikzpicture}
The polar coordinates example compiles fine with pdflatex. But with htlatex it gives this error
htlatex foo.tex "nma"
and the error
(/usr/local/texlive/2014/texmf-dist/tex/generic/tex4ht/html4.4ht)
(/usr/local/texlive/2014/texmf-dist/tex/generic/tex4ht/html4-math.4ht))
(./foo.aux))
! Package pgf Error: No shape named 30:2 is known.
See the pgf package documentation for explanation.
Type H <return> for immediate help.
l.11 \draw let \n1={2} in (0,0) -- (30:\n1)
;
? x
The file nma.cfg used above just has this catcode command: (my .cfg file is much larger, but I narrowed it down to this one line) Here is the nma.cfg file to use to reproduce the error.
\Preamble{ext=htm,charset="utf-8",p-width,pic-align}
\catcode`\:=11 \catcode`\@=11
\begin{document}
\EndPreamble
Without using the .cfg file, htlatex compiles the polar coordinates example ok and generated the image
htlatex foo.tex
I think I will end up removing this catcode line from my .cfg file, since I do not know now exactly why it is there and hope nothing else breaks.
But I was wondering if someone have an idea why would this happen. It might indicate a more serious problem somewhere else, this is why I posted this.
I also just updated to the latest TL 2014. Here is the filelist for reference
