[Tex/LaTex] No indent for verbatim environment

Question

I would like to deactivate the indent for the verbatim environment, such that left margin is the same for everything.

\documentclass{article}
\usepackage{verbatimbox}
 \makeatletter
 \setcounter{VerbboxLineNo}{-1}
 \renewenvironment{verbnobox}{%
  %  \setcounter{VerbboxLineNo}{-1}%
   \let\my@par\par%
   \def\verbatim@processline{%
  {\addtocounter{VerbboxLineNo}{1}%
 \@tmp\setbox0=\hbox{\@tmp\the\verbatim@line}%
 \hsize=\wd0 \the\verbatim@line\my@par}}%
 \verbatim\verbbox@inner%
   }
  {%
  \endverbatim%
  \global\def\@tmp{}%
    \addtocounter{VerbboxLineNo}{-1}%
   }
  \makeatother
  \begin{document}
   \def\tmp{\makebox[0pt][r]{\scriptsize\theVerbboxLineNo\ \smash{%
    \rule[-1.4\dp\strutbox]{1pt}{1.4\baselineskip}}\ }\small}
  NO INDENT SHOULD BE AFTER THIS 
  \begin{verbnobox}[\tmp]
   ADASFASFASF
  \end{verbnobox}
  NO INDENT SHOULD BE AFTER THIS 
 \begin{verbnobox}[\tmp]
  AFASDASFASGASDF

   \end{verbnobox}
   RESET LINE NUMBERS
  \setcounter{VerbboxLineNo}{-1}
  \begin{verbnobox}[\tmp]
   Reset Line Numbers should appear here
   \end{verbnobox}
   \end{document}

Answer 1

Simply removing the leading space from your verbatim content takes care of the problem.

Normally, leading spaces in LaTeX code are ignored. But that is not the case in verbatim style environments, where spaces are interpreted literally.

\documentclass{article}
\usepackage{verbatimbox}
 \makeatletter
 \setcounter{VerbboxLineNo}{-1}
 \renewenvironment{verbnobox}{%
  %  \setcounter{VerbboxLineNo}{-1}%
   \let\my@par\par%
   \def\verbatim@processline{%
  {\addtocounter{VerbboxLineNo}{1}%
 \@tmp\setbox0=\hbox{\@tmp\the\verbatim@line}%
 \hsize=\wd0 \the\verbatim@line\my@par}}%
 \verbatim\verbbox@inner%
   }
  {%
  \endverbatim%
  \global\def\@tmp{}%
    \addtocounter{VerbboxLineNo}{-1}%
   }
  \makeatother
  \begin{document}
   \def\tmp{\makebox[0pt][r]{\scriptsize\theVerbboxLineNo\ \smash{%
    \rule[-1.4\dp\strutbox]{1pt}{1.4\baselineskip}}\ }\small}
  NO INDENT SHOULD BE AFTER THIS 
  \begin{verbnobox}[\tmp]
ADASFASFASF
  \end{verbnobox}
NO INDENT SHOULD BE AFTER THIS 
 \begin{verbnobox}[\tmp]
AFASDASFASGASDF

   \end{verbnobox}
   RESET LINE NUMBERS
  \setcounter{VerbboxLineNo}{-1}
  \begin{verbnobox}[\tmp]
Reset Line Numbers should appear here
   \end{verbnobox}
   \end{document}
