Rendering with text and code block

Question

How to get, in Latex, this kind of rendering with firstly a text and just after a block of code with a shaded grey background ? I would like to get the same font for code block.

Answer 1

Your example shows a fixed font for the code. Using package ffcode might be one way.

\documentclass{article}
\usepackage{ffcode}
\begin{document}
\begin{ffcode}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{ffcode}
\end{document}

With package minted though you can have several themes with colored characters. Note that I have also customized a background color using the xcolor package for the vim theme as the characters weren't easily visible.

\documentclass{article}
\usepackage{minted}
\usepackage{xcolor}
\colorlet{myblack}{black!50!white}
\begin{document}
\section{Minted styles with non-italic comments}
\subsection{Light theme}
\subsubsection*{\texttt{perldoc}}
\usemintedstyle{perldoc}
\begin{minted}[linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsubsection*{\texttt{rrt}}
\usemintedstyle{rrt}
\begin{minted}[linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsubsection*{\texttt{pastie}}
\usemintedstyle{colorful}
\begin{minted}[linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsubsection*{\texttt{colorful}}
\usemintedstyle{colorful}
\begin{minted}[linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsubsection*{\texttt{vs}}
\usemintedstyle{vs}
\begin{minted}[linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsection{Dark theme}
\subsubsection{\texttt{vim}}
\usemintedstyle{vim}
\begin{minted}[bgcolor=myblack,linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}
\subsubsection*{\texttt{monokai}}
\usemintedstyle{monokai}
\begin{minted}[bgcolor=black,linenos]{r}
set.seed(123)
do grid
y <- rcoga(100000, c(2, 5, 7), c(3, 2, 4))
grid <- seq(0,15,length.out=100)
calculate pdf and cdf
\end{minted}

Note: For using any of these packages; you need to install python3-pygments package and invoke --shell-escape flag in the terminal as follows.

pdflatex --shell-escape filename.tex
