Text Formatting ⇒ Using listings to create code that can be copied and pasted

[squiggle]

Hello,
I would really like to make a pdf that has code that can be copied and pasted into an editor and run, however, when I use:

\documentclass{article}
\usepackage{listings}
\begin{document}
\lstset{language=C}
\begin{lstlisting}
// Basic command
fprintf("I'm sad this doesn't work");
\end{lstlisting}
\end{document}

And copy and paste from the resultant pdf into a text editor, it looks like this:

// B a s i c command
f p r i n t f ( ” I ’m sad t h i s doesn ’ t work ” ) ;

I'd like to not have those spaces between each letter. I have tried tweaking things with \lstset, however, nothing I have tried yet seems to work.

Add this option to your \lstset command:

Code: Select all

columns=fullflexible

You may also want to use a monospaced font for your code listings; it just looks better. I use the beramono package for that. Here's how I would do your code:

Code: Select all
