Hi all,

Is there a *reverse* of this solution? I'm trying to go from LaTeX to 
markdown/html for posting to a Jekyll blog, but pandoc parses out much of 
the algorithm/algorithmic environments, and does not put the contents in a 
div like it does for theorems/proofs.

With the input:

\begin{algorithm}
    \Require $x > 0$.
    \Procedure{SquareX}{$x$}
      \State $x \gets x^2$
      \State \Return $x$
    \EndProcedure
\end{algorithm}

Currently the output is:

$x > 0$. $x \gets x^2$ $x$

I'd like to have to something like:

<div class="algorithm">
    <span class="Require">$x > 0$</span>
    <span class="Procedure">SquareX</span>($x$)
    <span class="State">$x \gets x^2$</span>
    <span class="State" class="Return">$x$</span>
    <span class="EndProcedure"></span>
</div>

or something to that effect to allow formatting of the individual elements.

See also my StackOverflow question 
<https://stackoverflow.com/questions/65930404/pandoc-latex-to-markdown-do-not-parse-environment>
 and Jekyll Talk discussion 
<https://talk.jekyllrb.com/t/kramdown-latex-usepackage-algorithm-pseudocode/2861/7?u=broesler>
.

I can do my own wrangling and add a verbatim environment before running it 
through pandoc and then parse that chunk of the markdown file afterwards, 
but I was curious if there was a more elegant solution to dealing with 
unknown environments.

Thanks,
Bernie
