verbatim with black background and white text

Question

How could I set up a verbatim-environment which has

• black background
• white text in scriptsize ?

Answer 1

Here is a solution inspired by the code of the moreverb package and using code lines of it:

\documentclass{article}
\usepackage{color}
\usepackage{verbatim}
\makeatletter
\def\inverseverbatim{%
  \color{white}\scriptsize
  \def\verbatim@processline{%
    {\setbox0=\hbox{\the\verbatim@line}%
    \hsize=\wd0 \the\verbatim@line\par}}%
  \@minipagetrue
  \@tempswatrue
  \@totalleftmargin\z@
  \setbox0=\vbox\bgroup \verbatim
}
\def\endinverseverbatim{%
  \endverbatim
  \unskip\setbox0=\lastbox
  \egroup
  \colorbox{black}{\box0}%
}
\makeatother
\begin{document}
Test:

\begin{inverseverbatim}
\begin{document}
\end{document}
\end{inverseverbatim}
\end{document}
