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}

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}

  • Thanks you very much for your rapid answer!! I had tried it before, and I still have the same error... I'm working with TexMaker on Mac Os X, and the coloration begins to be all red after my old "\begin{verbatim}" or the new "\verbatim", till the end of the file. Any idea?

  • @MathTolliob: No, I haven't. I have shown you that it works on Linux and TL 2016, TeXMaker is an 'editor' only -- I don't use such 'editors' Commented Aug 18, 2016 at 13:25
