The following is a minimal example which demonstrates my problem. The error

TeX capacity exceeded, sorry [input stack size=5000] \end{latexresult}

is depending more or less on the number of codelines, not the actual code (therefore it is so long). One can comment out nearly any line and the error vanishes. I have no clue what could cause the problem. I have mdframed in mind, but can not see what should cause the error.

\documentclass[]{scrbook}

\usepackage{url}
\RequirePackage{etoolbox}
\RequirePackage{filecontents}
\RequirePackage{mdframed}

\RequirePackage{listings}

\lstnewenvironment{latexcode}{}{}
\newenvironment{latexresult}{%
Result:
\mdframed[skipabove=6pt]%

EDIT: I uncommented one line to let it compile again and got this filelist then:

afterwards I updated texlive and then mdframed changed to version 0.9e and many packages are loaded which were not loaded before:

mdframed.sty 2011/09/11 v0.9e: mdframed
...

md-frame-0.mdf 2011/09/10 v0.9e: md-frame-0

now it compiles without error.

As mentioned in the comments, the code as provided compiles fine for me using TeXLive2011, so perhaps you are using an older version of some package. What follows is not a direct solution to the problem reported here, but rather an alternate way of displaying code:

If you want to show LaTeX code and it's output you should consider using the showexpl package along with thelistings package as that produces very nice output:

enter image description here

\documentclass[]{scrbook}

\usepackage{url}
\usepackage{xcolor}

\usepackage{listings}
\usepackage{showexpl}
    \lstset{
        backgroundcolor=\color{yellow},
        basicstyle=\small\ttfamily,% print whole listing small
        keywordstyle=\color{blue}\bfseries\underbar,
        numbers=left, numberstyle=\tiny, stepnumber=2, numbersep=5pt,
        showstringspaces=false
    }
    \lstloadlanguages{[LaTeX]TeX}


\begin{document}
\begin{LTXexample}[pos=b]
The standard commands for font attributes:  
\textbf{bold}, \textit{italic}, \textsl{slanted},
\textsf{sans serif}, \textsc{small caps} and
\texttt{monospaced typewrite}.
And any combination of them:
\textit{\textbf{bold italic}},
\textsl{\textbf{bold slanted}},
\textsf{\textbf{bold sans serif}},
\textsc{\textbf{bold small caps}}
\textsl{\textsf{sans serif slanted}}. 
\end{LTXexample}

The url package provides a failsafe way to print
urls with characters not allowed by LaTeX.

\begin{LTXexample}
\url{http://www.dante.de}
\end{LTXexample}

  • showexpl can not be modified in its style and using LTXexample within an iscsdef is not allowed (as with any verbatim material). So what I do is more or less an alternative version of LTXexample where the code is exported to a file before. Oct 3, 2011 at 21:21
