[Tex/LaTex] How to include (print) Latex source code in generated pdf

pdfpdftex

I want to include the source code of my latex generated pdf file in the pdf file itself as printed text. Is there any way to do this?

Best Answer

if the purpose of this exercise is to make the source code visible to readers of the pdf file, say to document self-contained code examples, i've had excellent results with this simple approach.

\documentclass{article}
\usepackage{verbatim}

% your preamble

\begin{document}

% your text

\newpage
\verbatiminput{\jobname.tex}
\end{document}

Most recipients shouldn't find it inconvenient to receive a zip file of all the needed files?

The alternative would be to (for example) base64 encode the pdf file so it is all safe characters and put it in a filecontents environment in the latex file and then specify a graphic rule which base64 decodes the file that latex will then write. But then you have to make sure the recipient's latex setup allows calling external scripts (and that they have a necessary decoder) which is harder to setup usually than simply unzipping an archive.

pdfTeX contains the primitive \pdfmdfivesum for this purpose, available in recent XeTeX as \mdfivesum and implemented in Lua for LuaTeX in the pdftexcmds package. Using the latter as a wrapper we might have

\documentclass{article}

\usepackage{blindtext}
\usepackage{fancyhdr}
\usepackage{pdftexcmds}
\makeatletter
\ifx\pdf@filemdfivesum\undefined\def\pdf@filemdfivesum#{\mdfivesum file}\fi
\let\filesum\pdf@filemdfivesum
\makeatother
\pagestyle{fancy}
\fancyhf{}

\cfoot{\filesum{\jobname}}

\begin{document}
\blindtext[5]
\end{document}

The primitive syntax (if we assume pdfTeX/XeTeX):

\documentclass{article}

\usepackage{blindtext}
\usepackage{fancyhdr}
\makeatletter
\ifx\pdfmdfivesum\undefined
  \let\pdfmdfivesum\mdfivesum
\fi
\edef\filesum{\pdfmdfivesum file {\jobname}}
\makeatother
\pagestyle{fancy}
\fancyhf{}

\cfoot{\filesum}

\begin{document}
\blindtext[5]
\end{document}
