[tex4ht] help on syntax add a \Configure{@HEAD}

[Michal Hoftich]

Hello,

the issue here is that TeX commands are expanded in \HCode{}, so in
your case these lines are causing troubles:

  inlineMath: [ ['$','$'], ["\\(","\\)"] ],
  displayMath: [ ['$$','$$'], ["\\[","\\]"] ]

you have to prevent expansion of these commands and characters. You
can use `\unexpanded` for this purpose, this works for me:

 \Configure{@HEAD}{\HCode{%
     <script type="text/x-mathjax-config">\Hnewline
       MathJax.Hub.Config({\Hnewline
         extensions: ["tex2jax.js"],
         jax: ["input/TeX", "output/HTML-CSS"],
         tex2jax: {
           \unexpanded{inlineMath: [ ['$','$'], ["\\(","\\)"] ],}\Hnewline
           \unexpanded{displayMath: [ ['$$','$$'], ["\\[","\\]"] ],}\Hnewline
           processEscapes: true
         },
         "HTML-CSS": { availableFonts: ["TeX"] }
       });\Hnewline
     </script>
  }}

Best regards,
Michal
