ifmmode

[jtwspoon1]

I am trying to use pandoc on a LaTeX document that uses ifmmode, but the resulting html file shows that pandoc did not process ifmmode properly.
In LaTeX source: \newcommand{\sig} {\ifmmode\sigma\else\mbox{$\sigma$}\fi}
in html output: wherever \sig is referenced, pandoc simply displays the source command in red rather than interpreting it properly .
Any idea why and/or how to fix?

I found a workaround. I have TeXLive installed and discovered that this distribution includes make4ht, which produces html output from a LaTeX source file without the glitches I have experienced with pandoc (including more than just problems with ifmmode).

I will add support for \ifmmode.
