Package minted: \mint Command Not Working Inside tabularx Environment

Question

The question, How to embed a minted environment inside a tabular environment?, addresses a similar issue, but I am using:

1. the tabularx package, and
2. the inline \mint command

Is there a workaround available for this?

\documentclass[10pt]{article}
\usepackage[scaled]{beramono}
\usepackage[T1]{fontenc}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{minted}


\begin{document}

\begin{tabularx}{\linewidth}{@{}lrX}

Type & Meaning & Size \\
\cmidrule(r){1-1} \cmidrule(lr){2-2} \cmidrule(lr){3-3}

\mint{c++}|float| & single precision floating point  & 6 significant digits \\
            &               & Typically represented in 32 bits \\   

\mint{c++}|double| & double precision floating point  & 10 significant digits \\
            &               & Typically represented in 64 bits \\

\mint{c++}|long double| & extended precision floating point  & 10 significant digits \\
            &               & Typically represented in 96 or 128 bits \\        

\bottomrule                                                     

\end{tabularx}              

\end{document}

Answer 1

There are at least two ways to get this to work.

First method

Edit: For this approach to work, you will need to use the patch for \mint that is here.

Use \savebox. Before the tabularx, define something like the following for each of the terms you need.

\newsavebox{\floatinabox}
\begin{lrbox}{\floatinabox}
\mint{c++}|float|
\end{lrbox}

Then, inside the tabularx, use something like \usebox{\floatinabox}.

The lrbox typesets its contents in a box, and saves the box for later use rather than inserting the box in the document.

This same approach can be used for inserting a minted environment, except that a minipage is required to allow linebreaks (see this).

\newsavebox{\mintedbox}
\begin{lrbox}{\mintedbox}
\begin{minipage}{3cm}
\begin{minted}{c++}
long double
\end{minted}
\end{minipage}
\end{lrbox}

Second method

Use the Pygments highlighting from my pythontex package. The \pygment command takes the same arguments as \mint, and usually works in these types of situations as long as # and % aren't involved. I checked, and it does work in this case.
