Automating mathjax customisation

[tvercaut]

Somewhat of a follow-up from #23, I am wondering if there is a way to bypass the need for manually "wrapping" math macros with \CustomizeMathJax?

I have documents using definitions such as

\newcommand{\bA}{\boldsymbol{A}}
\DeclareMathOperator{\Expec}{\mathbb{E}}

which don't render well by default with lwarp. The lwarp documentation mentions that the following should be added to correct this:

\begin{warpMathJax}
\CustomizeMathJax{\newcommand{\bA}{\boldsymbol{A}}}
\CustomizeMathJax{\DeclareMathOperator{\Expec}{\mathbb{E}}}
\end{warpMathJax}

meaning we end up with "duplication":

\newcommand{\bA}{\boldsymbol{A}}
\DeclareMathOperator{\Expec}{\mathbb{E}}

\begin{warpMathJax}
\CustomizeMathJax{\newcommand{\bA}{\boldsymbol{A}}}
\CustomizeMathJax{\DeclareMathOperator{\Expec}{\mathbb{E}}}
\end{warpMathJax}

I assume this means there is no easy way of automating this but I thought I would ask in case I missed it. Can this be bypasssed while still having nice mathjax output?

I understand this can be really complex as \newcommand and others can be used for non-math related things. So maybe an intermediate approach could be to only require a minimal manual change? Something along the lines of only needing to surround math macros with a bespoke environment (say addForWarpMathJax) which would automatically add the \CustomizeMathJax versions?

\begin{addForWarpMathJax}
\newcommand{\bA}{\boldsymbol{A}}
\DeclareMathOperator{\Expec}{\mathbb{E}}
\end{addForWarpMathJax}

It may be possible to form something like your addForWarpMathJax, which would have to execute the contents for LaTeX and also process the contents line-by-line for MathJax. Some things are not directly supported in MathJax and must be emulated, meaning the code would look different than the LaTeX version. But I may add this to the todo list.

Thanks. That would be handy!
