Using a Verbatim inside bclogo in a new environment definition

Question

I would like to create a new environment to provide some LaTeX code (or from other languages)

So far, I tried the following code

\usepackage{bclogo}
\newenvironment{code}
{   \begin{bclogo}
        [couleur = black!10, couleurBord = black!50,
        arrondi = 0.1, logo = \bccrayon]
        {Code \LaTeX :}

        \bigskip

        \begin{verbatim}
}
{       \end{verbatim}
    \end{bclogo}
}

But, this creates an error during the compilation...

! File ended while scanning use of \next. \par <*> essai3.tex

I suspect you have forgotten a '}', causing me to read past where you wanted me to stop. I'll try to recover; but if the error is serious, you'd better type E' orX' now and fix your file.

! Emergency stop. <*> essai3.tex

*** (job aborted, no legal \end found)

Here is how much of TeX's memory you used:

...

! ==> Fatal error occurred, no output PDF file produced!

If someone have an idea to get through this error, I would sincerely say "Thank you very much, Master"

You can use fancyvrb:

\documentclass{article}

\usepackage{fancyvrb}

\usepackage[tikz]{bclogo}
\newenvironment{code}
{\VerbatimEnvironment
  \begin{bclogo}[couleur = black!10, couleurBord = black!50,
  arrondi = 0.1, logo = \bccrayon]
  {Code \LaTeX :}\par\nobreak\bigskip
  \begin{Verbatim}}
{\end{Verbatim}\end{bclogo}}

\begin{document}
\begin{code}
\documentclass{article}
\begin{document}
Hello
\end{document}
\end{code}
\end{document}

Answer 2

Nesting verbatim inside macros is not possible, but it is possible inside environments using the starter and 'end' - commands of the verbatim environment, i.e. \verbatim and \endverbatim.

At the end of my code answer I provide also a way with tcolorbox showing LaTeX code and its compilation:

\documentclass{article}

\usepackage{verbatim}

\usepackage[most]{tcolorbox}
\usepackage[tikz]{bclogo}
\newenvironment{code}
{%   
  \bclogo[couleur = black!10, couleurBord = black!50,
  arrondi = 0.1, logo = \bccrayon]
  {Code \LaTeX :}
  \bigskip
  \verbatim
}
{ 
  \endverbatim
  \endbclogo
}

\begin{document}
\begin{code}
\documentclass{article}
\usepackage[most]{tcolorbox}
\begin{document}
\begin{tcblisting}{listing only}

\end{tcblisting}

\end{document}
\end{code}

And a \verb!tcolorbox! version:

\begin{tcblisting}{colback={white!40!yellow}}
\LaTeXe\ is nice!
\end{tcblisting}

\end{document}


\end{document}
