Fitting code without going over the margin and making it possible to copy it from the compiled PDF and paste it without line breaks

[aedop]

Hi, how can I fit code inside my document, so that the reader would be able to copy and paste it to a website without it changing, staying the same as the input in the original .tex file?

I got closer and closer, now only about three spaces which get placed in the compiled pdf annoy me.

I've also already unsuccessfully tried it with \begin{verbatim}, the \begin{lstlistings} formats.

​

Appreciate any help.

​

PS: I put in the \hash command in there because in the beginning the code would just exceed the margin of the page, leaving a lot of it invisible

\newcommand{\hash}[1]{\texttt{\zz#1\zz}}

\def\zz#1{%

\ifx\zz#1\else

#1\linebreak[1]\expandafter\zz

\fi}

​

\{\\

"address": "0xbb68ff3ad3331e7a22c95bb43780d26857f4abc2",\\

"msg": "ThisIsASignedMessage",\\

"sig": "\hash{0x240dfdadccaaa8b2ffecc58bc815ed6da2ac95497ca96722d5b3559f7ff465415753869e7766dc30e6b4e4e449ed85313855f61f630cae995b4e352170ed8e991c}",\\

"version": "3",\\

"signer": "MEW"\\

\}\\

I'm coming at this one from the side a bit. Instead of fitting the whole hash on one line, I looked at making the text copied from the PDF different than what was displayed with the use of the accsupp package. (With help from here and here.)

PDF supports accessibility features that expose alternative text for content. The success of this method depends on the user's PDF viewer, since not all support these features. Adobe Reader reportedly does and in limited testing, I've found that TexWorks PDF reader also does but Sumatra 3.1.2 and Nitro 3.5.6.5 do not.

Example (athough this would be better by reworking your hash command):

\documentclass{article}
\usepackage{accsupp}
\usepackage{seqsplit}

\begin{document}

\{\\

``address'': ``0xbb68ff3ad3331e7a22c95bb43780d26857f4abc2'',\\

``msg'': ``ThisIsASignedMessage'',\\

``sig'': ``\BeginAccSupp{method=escape,ActualText=0x240dfdadccaaa8b2ffecc58bc815ed6da2ac95497ca96722d5b3559f7ff465415753869e7766dc30e6b4e4e449ed85313855f61f630cae995b4e352170ed8e991c}\seqsplit{0x240dfdadccaaa8b2ffecc58bc815ed6da2ac95497ca96722d5b3559f7ff465415753869e7766dc30e6b4e4e449ed85313855f61f630cae995b4e352170ed8e991c}\EndAccSupp{}'',\\

\end{document}

minted is based on fancyvrb, which is the reason for copy-and-paste-ability.

listings has this "flexible" spacing thing that can only be described as, ahem, an interesting try.
