Ah, exce= llent. The additional div makes a big difference in processing.

I realized I over-simplified my = example. It's actually:

\begin{algorithm}
\caption{...}
\label{alg:my_= alg}
\begin{algorithmic}
...statements...
= \end{algorithmic}
\end{algorithm}

"algorithm" is just a float like "fig= ure" or "table", and "algorithmic" actually defines the commands "\Require"= , etc. pandoc now makes divs for both algorithm and algorithmic, but still = loses the commands, as you've mentioned.

I've just been using a bash/sed script to pre-proce= ss the latex document before processing with pandoc which seems to work wel= l for now.

Pandoc's latex reader doesn't know about the algorithm

With the latest pandoc release, we get this outpu= t with
pandoc -f latex = -t html --mathjax on your input:

<div class=3D"algorithm= ">
<p><span= class=3D"math inline">\(x &gt; 0\)</span>. <span class=3D"= math inline">\(x \gets x^2\)</span> <span class=3D"math inline"= >\(x\)</span></p>
</div>

Better, though we lose the line brea= ks and we lose \Require, etc.

If you want to handle this pr= operly, one option would be to use
pandoc -f latex+raw_tex --lua-filter handle_algorithm.lua

You'd have to write handle_algorithm.lua, but what it would do=
is find raw latex bloc= ks with algorithm environments and convert
them to some form that works in your Jekyll blog.

You might also try this approach:

Add macro de= finitions to your latex:

\renewcommand{\Require}{1]{Require= #1}

and so on for \State and \Procedure.

Then pandoc will parse them and you'll get better output. That
gets you almost all the way there,= except for the newlines and
<= span style=3D"caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size:= 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; = letter-spacing: normal; text-align: start; text-indent: 0px; text-transform= : none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: = 0px; text-decoration: none; float: none; display: inline !important;" class= =3D"">whitespace, if they're significant in this environment.

For the newlines, you could add a filter that intercepts
SoftBreak.

Hi all,

= Is there a *reverse* of this solution? I'm trying to go from LaTeX to 
markdown/html f= or 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}{$x$}
 &= nbsp;   \State $x \gets x^2$
   = ;  \State \Return $x$
   \EndProcedu= re
\end{algorithm}

Currently the= output is:

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

I'd like to have to something like:
=
<div class=3D"algorithm">
  &n= bsp;<span class=3D"Require">$x > 0$</span>
&nb= sp;  <span class=3D"Procedure">SquareX</span>($x$)   <span class=3D"State">$x \gets x^2$<= /span>
   <span class=3D"State" class=3D= "Return">$x$</span>
   <span class= =3D"EndProcedure"></span>
</div>

or something to that effect to allow formatting of the indi= vidual elements.

and Jekyll Talk discussion&= nbsp;
<h= ttps://talk.jekyllrb.com/t/kramdown-latex-usepackage-algorithm-pseudocode/2= 861/7?u=3Dbroesler>
.

I c= an do my own wrangling and add a verbatim environment before running it 
through pando= c and then parse that chunk of the markdown file afterwards, 
but I was curious if the= re was a more elegant solution to dealing with 
unknown environments.
Thanks,
Bernie

Yo= u need a filter, but it would be a simple one.

Something like

function latex(s)
 return pandoc.RawBlock('latex', s) 
end

function = Div(el)
 if el.classes[1] =3D=3D 'solution' then
   return { latex('\begin{solution}'), el.content, 
latex('\end{= solution}') }
 end
end

Hello,

I'm looking for advic= e on how to produce HTML and LaTeX from Markdown 
using 
fenced divs (or something else) to apply custom styles to specifi= c 
portions 
of the document. 

For exampl= e, I'm hoping to write something like this:

::= : solution
Solution text here.
:::

in order to produce this when HTML is the output (already = works):

<div class=3D"solution">
Solution text here.
</div>

and this when LaTeX/PDF is the output:

\begin{solution}
Solution text here.
\end{solu= tion}

This idea comes from Bookdown's 
<https://boo= kdown.org/yihui/bookdown/custom-blocks.html> Custom Blocks 
feature, but I'm wo= ndering if there's a way to do this with Pandoc, or 
if 
this would require a Lua filter. 

Thanks,
Chris=
