<div>I write lecture notes for my students including program listings in</div>
<div>the language R. I want to process these with tex4ht to HTML with</div>
<div>MathJax to post on my class webpages. The program listings use the</div>
<div>package "listing".</div>
<div><br>
</div>
<div>When processing with files (see below for example) with tex4ht, I get the following error:</div>
<div>! Missing } inserted.</div>
<div><inserted text> </div>
<div> }</div>
<div>l.9 S <-</div>
<div> 50</div>
<div><br>
</div>
<div>Answering with a "q" during each processing pass seems to ignore the</div>
<div>problem and produce a valid HTML file. The error does not</div>
<div>occur when processing with pdflatex, and the pdf is fine. </div>
<div><br>
</div>
<div>I want to automate the processing. Therefore, either fixing the problem</div>
<div>altogether (best!) or commanding tex4ht to run quietly without asking</div>
<div>(good enough!) would be a solution.</div>
<div><br>
</div>
<div>A minimal working example demonstrating the problem:</div>
<div>\documentclass[12pt]{article}</div>
<div>\usepackage{listings} %for computer code fragments</div>
<div><br>
</div>
<div>\begin{document}</div>
<div><br>
</div>
<div>Some text that precedes the listing for $S = 50$ in R notation.</div>
<div><br>
</div>
<div>\begin{lstlisting}[language=R]</div>
<div>S <- 50</div>
<div>\end{lstlisting} </div>
<div><br>
</div>
<div>\end{document}</div>
<div><br>
</div>
<div>Command and Envrionment:</div>
<div>htlatex minworkexample.tex "~/ht5mathjax,xhtml,mathml" " -cunihtf" "-cvalidate"</div>
<div><br>
</div>
<div>I'm using TeX Live 2014 on a Fedora 23 installation.</div>
<div><br>
</div>
<div>Thanks in advance!</div>
