Export source code of tex file

1. Export source code of tex file

I have to create a training guide for Maple as part of an assignment. Obviously I need to hand in the final PDF document, but I also need to hand in the LaTeX source code to prove that I created the document using LaTeX. Is there a way of exporting the source code with all the colours, indentation etc. still in place?

Comments

(JP-Ellis) Welcome to LaTeX! Welcome to TeX.SX! Just to clarify, where are you intending to export the LaTeX source? Are you looking to embed the TeX file into the PDF? or do you want to pretty-print the LaTeX source?
(George Wilson) Ideally, the LaTeX source code would follow the actual PDF document.
(jamesqf) I think you have a major misunderstanding here. The colors you may see as you write your LaTeX source (I’m assuming you mean syntax colorization?) are not part of LaTeX or the source file, they are applied by whatever editor you’re using to write the LaTeX code. Likewise, there’s no need to ’export’ the LaTeX file, as your editor should already have saved it on your hard drive. Indentation is a part of that file. You can, as others have said, include that file in your LaTeX document, or you can simply print it as a plain text file.
(Bakuriu) When they tell you to provide the sources it means you just hand them the .tex file so that they can compile them and check the output pdf is the same you handed in…

Here is a tcolorbox - listings way of inputting the document itself to the file and displaying the code.

\documentclass{article}


\usepackage[most]{tcolorbox}

\begin{document}
This is my nice \LaTeXe{} file.

It shows the code of itself:

\tcbinputlisting{breakable,listing file=\jobname.tex,listing only,colback=white!40!yellow,sharp corners}
\end{document}

[[][]] For breakable boxes:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage[most]{tcolorbox}

\begin{document}
This is my nice \LaTeXe{} file.

It shows the code of it self -- and here is some blind text to make the text longer

(George Wilson) I love that. My source code spans over many pages (over 300 lines at the moment) and this solution seems to not split the code over several pages. How can I solve this?
(user31729) @Will: Add the breakable option to the \tcbinputlisting options. See the updated code (but i did not add a new screen shot (yet))
(George Wilson) Just added that argument in. Thanks a lot, looks great!
(George Wilson) Another question, when the inputted code is in math mode, it goes off the screen. How can I prevent this?
(user31729) @Will: That’s another question ;-)

1.2. Answer 2

One possibility is to simply input the TeX file in a verbatim environment. A really neat option is the minted package which has nice syntax highlighting:

\documentclass{article}

\usepackage{minted}
\usepackage{mwe}

\begin{document}

\blinddocument

\clearpage

\inputminted[bgcolor=gray!10]{latex}{will.tex}

\end{document}

This places, on the last page, the following: [[][]] You can customize the appearance of the output in minted. If you don’t like minted, there are other packages to typeset code as well and you should be able to use them in essentially the same way. Have a search through this website to see a few other options.

1.3. Answer 3

I use this construction in the \LaTeX source for exercises for my students

\usepackage{verbatim}    
...
\newpage
\emph{
Here is the \LaTeX{} source for this document. You can cut it from the
pdf and use it to start your answers. I used the \verb!\jobname! 
\emph{macro for the source file name, so you can call your file by any
  name you like.}
\verbatiminput{\jobname}
\end{document}

try

\begin{verbatimwrite}{myfile}
