[luatex] luatex and minted

[Robert Alessi]

Thank you both.  I didn't pay attention to Scott's previous post,
sorry about that.

I now think it is clear enough ;)

This works, thank you!  Unfortunately, the following fails for the
same reason (namely ` instead of '):

---------------snip---------------
\documentclass{article}

\usepackage{minted}

\begingroup
\makeatletter
\catcode`\'=\active
\gdef\minted at patch@PYGZsq at i{\gdef\PYGZsq{\mbox{'}}}
\endgroup

\begin{document}

\begin{minted}{latex}
   a-`
\end{minted}

\end{document}
---------------snip---------------

Another way would be to have the hyphen itself inserted in a box, like
so: \def\PYGZhy{\mbox{\char`\-}}

This work, but unfortunately \PYGZhy is only defined in the
'default-pyg-prefix.pygstyle' file that is generated inside minted
output dir.  However, as this file is untouched if it exists, one can
modify this file after the first run.

Or this may boils down to inserting this in the preamble:

---------------snip---------------
\usepackage{etoolbox}
\usepackage{minted}
\makeatletter
\patchcmd{\minted at checkstyle}{\minted at input{%
          \minted at outputdir\minted at cachedir/\ifstrempty{#1}{default-pyg-prefix}{#1}.pygstyle}%
      }{\minted at input{%
          \minted at outputdir\minted at cachedir/\ifstrempty{#1}{default-pyg-prefix}{#1}.pygstyle}%
        \def\PYGZhy{\mbox{\char`\-}}}{}{}
\makeatother
---------------snip---------------

Thanks again!

Robert
