First, I agree that it doesn't seem feasible for latex2html to
implement all of TeX.
Below is a short simple program showing my current macros and
usage. I wrote the macros a long time ago, and on looking at
them again, they're kind of ugly. But they get the job done --
as long as I only want to use integers. That's starting to
feel restrictive.
There are various options for doing arithmetic on floating-point
values, including what seem to be a variety of LaTeX packages.
It occurs to me, however, that very likely none of them will do
what I want to, *because* I want to be able to print the total
at the top of the document. My current macros can do that using
\refstepcounter and \label, but I don't think any of the LaTeX
packages I've looked at would do that.
More and more I think I need to just write a preprocessor! "How
hard can it be" .... :-)?
==== start of .tex file ====
\documentclass{article}
% ---- macros ----
\newcounter{Tpoints}
\setcounter{Tpoints}{0}
\newcommand{\EndAll}{
\addtocounter{Tpoints}{-1}
\refstepcounter{Tpoints}
\label{tpoints}
}
\newcommand{\Points}[1]{
({#1} points)
\addtocounter{Tpoints}{#1}
}
% ---- document ----
\begin{document}
Total credit: \ref{tpoints} points.
\begin{enumerate}
\item \Points{10} Do this problem.
\item \Points{30} Do that problem.
\end{enumerate}
\EndAll
\end{document}
