My preamble is as follows:

\documentclass{llncs}
\usepackage{xcolor}
\usepackage{harvard}
\usepackage{listings}
\usepackage{chngcntr}
\makeatletter
\lst@InstallKeywords k{attributes}{attributestyle}\slshape{attributestyle}{}ld
\makeatother

}

I have the following listing in my document:

\begin{lstlisting}[basicstyle=\ttfamily, caption={class foo managing private memory},label={lst:baseFoo}]

class foo
{
  public:
    foo() { aReallyLargeArray = new char[123456789]; }
    ~foo() { delete [] aReallyLargeArray; }
  private:
    char* aReallyLargeArray;
};

int main(int argc, char** argv)
{
   foo bar;  
}

\end{lstlisting}\bigskip

However, indentation in the input is not preserved in the output. Note how the ~foo() destructor is indented much more than foo on the previous line. This improper indentation occurs in other listings of mine as well. I suspect it has to do with the ~... Any thoughts?

  • No problem here: http://i.stack.imgur.com/k5Dcl.png . May be you need an update for the tex distro. –  May 16 '14 at 02:09
  • The problem most likely stems from ~foo being preceded by a tab character, whereas foo (on the previous line) is preceded instead by 4 spaces; see http://tex.stackexchange.com/questions/166585/tabs-vs-spaces-in-listings-whats-the-difference-and-should-i-care. To avoid any surprises like this one, I recommend using spaces throughout your listing. – jub0bs May 16 '14 at 12:10

    In the future, please don’t break your code apart: keep the preamble and body in one minimal working example (MWE), so that people can copy & paste it easily and start working on an answer more quickly. – jub0bs May 16 '14 at 12:11
