[Tex/LaTex] Minted with frame and bgcolor

Question

I have a problem with minted. I have created a new minted environment like so:

\definecolor{dhscodebg}{rgb}{0.95,0.95,0.95}
\newminted[dhscode]{hs}{tabsize=4, fontsize=\footnotesize, frame=lines, framesep=\fboxsep, bgcolor=dhscodebg, rulecolor=\color{gray!40}}

If I use it like so:

\begin{dhscode}
foo :: Double -> Int
\end{dhscode}

The result is:

You will notice the space between the frame and where the background ends. Is there a way to get rid of this space?

Answer 1

This affects all your minted environments. One work around is to set \fboxsep to 0pt in the definition of minted@colorbg as follows.

\makeatletter
\renewenvironment{minted@colorbg}[1]{
\setlength{\fboxsep}{\z@}
\def\minted@bgcol{#1}
\noindent
\begin{lrbox}{\minted@bgbox}
\begin{minipage}{\linewidth}}
{\end{minipage}
\end{lrbox}%
\colorbox{\minted@bgcol}{\usebox{\minted@bgbox}}}
\makeatother

Here is a full minimal working example (MWE). (You should construct one in succeeding posts for speedier replies. A lot of answerers do not like to work from scratch.)

\documentclass[preview,border=5]{standalone}

\usepackage{minted}

\makeatletter
\renewenvironment{minted@colorbg}[1]{
\setlength{\fboxsep}{\z@}
\def\minted@bgcol{#1}
\noindent
\begin{lrbox}{\minted@bgbox}
\begin{minipage}{\linewidth}}
{\end{minipage}
\end{lrbox}%
\colorbox{\minted@bgcol}{\usebox{\minted@bgbox}}}
\makeatother

\definecolor{dhscodebg}{rgb}{0.95,0.95,0.95}
\newminted[dhscode]{hs}{tabsize=4, fontsize=\footnotesize, frame=lines, framesep=5\fboxrule,framerule=1pt,
bgcolor=dhscodebg, rulecolor=\color{gray!40}}
