How can I automatically include all source code files located in a given directory?

Question

Is there a way to include all files in a directory and all sub directories in a report as a code appendix using the listings package?

I know I can include each individual file using the listings package and \lstinputlisting, but I'm just wondering whether there is a quicker way to insert them in a code appendix...

Answer 1

A good solution that also works for listings was provided here: How to iterate through the name of files in a folder. You just have to modify the code like this:

\documentclass{article}
\usepackage{listings}

\makeatletter
\def\app@exe{\immediate\write18}
\def\listDir#1{%
  \app@exe{ls #1/* | xargs cat >> \jobname.tmp}%
  \lstinputlisting{\jobname.tmp}
  \AtEndDocument{\app@exe{rm -f #1/\jobname.tmp}}}
\makeatother

\begin{document}

\listDir{your_directory}

\end{document}

Note that, if you are running under windows, you will have to replace \app@exe commands by something like (not tested, but based on the answer given in the previous thread):

\app@exe{cmd /c dir /b * > \jobname.tmp}%
\AtEndOfDocument{\app@exe{rm -f #1/\jobname.tmp}}}

The code I gave will include all the files of the directory. If you want to only include files with a given extension you can specify it directly in \app@exe command.

Don't forget to compile using pdflatex -shell-escape yourfile.tex.

Answer 2

I was trying to use this to load python code. However, your example only listed the names of the files. Was that the intention? Anyway, the following seems to work for me. Is there a more elegent way?

\documentclass{article}
\usepackage[cache=false]{minted}
\usepackage{listings}
\usepackage{pgffor}
\usepackage{pgfplotstable}
\usemintedstyle{friendly} % Python Code Style

\makeatletter
\def\app@exe{\immediate\write18}
\def\createData#1{%
  \app@exe{cmd /c dir /b *.py > \jobname.dat}%
    \AtEndDocument{\app@exe{cmd rm -f #1/\jobname.dat}}}
\makeatother


\begin{document}

\createData{.}% from the current dir 
\pgfplotstableread[header=false]{\jobname.dat}{\mytable}
\pgfplotstablegetrowsof{\mytable}
\pgfmathsetmacro{\rows}{\pgfplotsretval-1}

\foreach \i in {0,...,\rows} {
                \pgfplotstablegetelem{\i}{[index]0}\of\mytable
        \subsection*{Source code for \textsf{\pgfplotsretval}}
                \inputminted[
                                        frame=lines,
                                        framesep=2mm,
                                        baselinestretch=1.2,
                                        %bgcolor=gray,
                                        fontsize=\footnotesize,
                                        linenos
                                        ]
                                        {python}{\pgfplotsretval}
}

\end{document}
