I was attempting to generate different programming languages code snippets to highlight the different syntax in different programming languages like: Python, Matlab and C++ (more to be added later).

In the code given below, I am getting the error:

! TeX capacity exceeded, sorry [input stack size=5000].
cl@chapter ->cl@chapter
@elt {matlab}
l.73 ...code,number within=chapter]{inputcppcode}
[3]{listing options={lan...

Can you tell me how to get rid of this error to get my file to compile correctly?

Thanks.

The problematic code is the numberwithin=chapter in the definitions. The article document class does not have a counter chapter since it does not have chapters and so resetting by chapter is not really a well-defined concept.

The same issue can be reproduced with

documentclass{article}

usepackage{tcolorbox}

tcbuselibrary{listings}

newcounter{a}

newcounter{b}



newtcbinputlisting[use counter=a, number within=chapter]{inputverba}[1]{listing file={#1}}

newtcbinputlisting[use counter=b, number within=chapter]{inputverbb}[1]{listing file={#1}}



usepackage{filecontents}

begin{filecontents*}{sample.x}

Lorem

end{filecontents*}



begin{document}

inputverba{sample.x}

inputverbb{sample.x}

end{document} 

and ultimately by tracing back what number within does also with

documentclass{article}

newcounter{a}

newcounter{b}



makeatletter

@addtoreset{a}{chapter}%

@addtoreset{b}{chapter}%

makeatletter



begin{document}

Lorem

end{document} 

This error occurs when you want to @addtoreset a second time to a counter that does not exist.

Incidentally, @removefromreset has a bit of error checking here, according to source2e (p. 147, file m)

Even through this is internal and the programmer should know what he/she is doing we test here if counter #2 is defined.

but no such error checking is done for @addtoreset.

The solution is to either pick an existing counter to reset with, i.e. number within=section, or to use a document class with chapters, i.e. report or book.
