How to use \scalebox around my environment?

Question

I tried putting scalebox{.2} while defining my new environment, but it is not being applied:

\documentclass[10pt,a5paper,twoside]{memoir}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage[brazil]{babel}
\usepackage[showframe,pass]{geometry}

\usepackage{graphicx}

\makeatletter

\newenvironment{myenvironment}[0]
{scalebox{.2}\{myenvironment start\par\verbatim}
{\endverbatim\endgraf myenvironment end\}}

\makeatother

\begin{document}

\begin{myenvironment}
    test
\end{myenvironment}

\end{document}

How to use \scalebox around my environment?

Answer 1

Two ways to do this with the verbatimbox package. Note that approach two requires a scalable font, which is why I added the lmodern package.

\documentclass[10pt,a5paper,twoside]{memoir}

\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}

\usepackage[brazil]{babel}
\usepackage[showframe,pass]{geometry}

\usepackage{graphicx,verbatimbox}

\begin{document}

\begin{verbbox}
test
of my
\%\@# verbatim stuff
\end{verbbox}
\noindent\scalebox{.2}{\theverbbox} 

versus normal size

\begin{verbnobox}[\fontsize{2pt}{2.5pt}\selectfont]
test
of my
\%\@# verbatim stuff
\end{verbnobox}

Back to normal
\end{document}

Answer 2

Or use the environ package.

\documentclass{article}

\usepackage{graphicx}
\usepackage{environ}

\NewEnviron{test}{%
\scalebox{5}{\BODY}}

\begin{document}
    This is nuts
\begin{test}
    This is nuts
\end{test}

\end{document}

Answer 3

Quite similar to \scalebox in column specification operator >{...}, however verbatim also cannot be put inside hbox so you need the primitive setbox as suggested in https://tex.stackexchange.com/a/41707/250119:

%! TEX program = lualatex
\documentclass[10pt,a5paper,twoside]{memoir}
\usepackage{graphicx}
\newbox\mybox
\makeatletter
\ExplSyntaxOn
\newenvironment{myenvironment}[0]
{
    \setbox\mybox\vbox\bgroup
    myenvironment~start
    \par
    \verbatim}
{
    \endverbatim
    \endgraf myenvironment~end
    \egroup
    \scalebox{.2}{\box\mybox}}
\ExplSyntaxOff

\makeatother

\begin{document}
\begin{myenvironment}
    test
\end{myenvironment}
\end{document}

I prefer \ExplSyntaxOn, but you can also % every lines.

Answer 4

If you want verbatim mode, you can use fancyvrb

\documentclass[10pt,a5paper,twoside]{memoir}

\usepackage[T1]{fontenc}
\usepackage[brazil]{babel}
\usepackage{fancyvrb}
\usepackage{graphicx}

\usepackage[showframe,pass]{geometry}

\makeatletter
\newsavebox{\mybox}
\newenvironment{myenvironment}
 {\VerbatimEnvironment\begin{lrbox}{\mybox}\begin{BVerbatim}}
 {%
  \end{BVerbatim}\end{lrbox}%
  \par\smallskip\hrule\smallskip % or whatever you want at the top
  \noindent\scalebox{.2}{\usebox{\mybox}}%
  \par\smallskip\hrule\smallskip % or whatever you want at the bottom
  \@endpetrue
 }
\makeatother

\begin{document}

Some text before the scaled verbatim
some text before the scaled verbatim
some text before the scaled verbatim
\begin{myenvironment}
test
\end{myenvironment}
Some text after the scaled verbatim
some text after the scaled verbatim
some text after the scaled verbatim

\end{document}
