How can I enable search within verbatim sections of a LaTeX document rendered to PDF?

Question

I'm generating a LaTeX document as so:

\documentclass{article}
\usepackage[letterpaper, margin=0.75in]{geometry}
\usepackage[tocindentauto]{tocstyle}
\usetocstyle{standard}
\usepackage{parskip}% http://ctan.org/pkg/parskip
\usepackage[hidelinks]{hyperref}
\usepackage{spverbatim}
\usepackage{listings}
...
\subsubsection{HEADER\_SNTP\_POLL\_FAILURE}
Request function: \verb#SNTP_POLL_FAILURE#

Assignments: \begin{lstlisting}
msg = some_interesting_function_call(&etc)
\end{lstlisting}

The difficulty I'm having is twofold:

1. The header is not searchable. If a user searches for "HEADER_SNTP_POLL_FAILURE" they do not get a hit on the subsubsection header. However, "SNTP_POLL_FAILURE" does get a hit, on the "Request function" text inside the \verb.
2. If a user searches for "some_interesting_function_call" they will not get a hit on the lstlisting. And if I copy the text out of the PDF and into a terminal, it comes out like this: s ome i n t e r e s t i n g f u n c t i o n c a l l This makes the code listing pretty useless, as it makes using the document as a reference pretty awkward.

How can I solve this? I want the listings to be useful as a copy-and-paste source, and I want to be able to search for symbols in the listings and in section headings.

Answer 1

The minted package renders code snippets searchable and copyable. The package provides syntax coloring and supports line breaking with the environment option breaklines=true. If you don't want coloring, the lexer text can be used. Run with pdflatex --shell-escape. Additionally, pygmentize must be installed on the system (see, e.g., How to use minted under MikTeX and Windows 7? or I can't get minted package to work under Ubuntu (pygments error)).

MWE:

\documentclass{article}
\usepackage{minted}
\begin{document}
\section{HEADER\_SNTP\_POLL\_FAILURE}
Request function: \verb#SNTP_POLL_FAILURE#\\
Assignments:
\begin{minted}[breaklines=true]{cpp}      % C++ lexer
msg = some_interesting_function_call(&etc)
VectorHistogram::VectorHistogram(size_t bins, size_t cache) : bins(std::vector<double>(bins)), cache(std::min(cache, MAX_CACHE_ENTRIES)) {}
\end{minted}
\end{document}

Result:
