# Bold code in listings environment

I want to do a box like this

but the bold text doesn't appear.

Edited:

\documentclass{article}
\usepackage{listings,xcolor,etoolbox,lmodern}
\definecolor{verbgray}{gray}{0.9}
\newcommand*\prompt{}% empty default
\lstnewenvironment{sh}{%
% redefine bash prompt:
\def\prompt{user@linux:\textasciitilde\$\space}% \lstset{backgroundcolor=\color{verbgray}, frame=single, framerule=1pt, basicstyle=\ttfamily, columns=fullflexible, escapechar=@ }% }{} \begin{document} \begin{sh} @\prompt\space\textbf{date}@ Thu Oct 25 13:51:54 EDT 2007 \end{sh} \end{document}  • A couple pointers, you need a comma after columns=fullflexible. Also, you're misreading the syntax of the escape character, it should be either escapechar=@ or escapechar=\@. – A.Ellett Jan 24 '15 at 22:22 • Thanks I changed that, but still doesn't seems to work – Arturo Jan 24 '15 at 22:24 • Because of the indentation I'd add gobble=4 to the setup. And I'd probably use language=bash,keywordstyle=\bfseries,morekeywords=date or something instead of escapechars. (This actually depends if date is the only occurence where you want bold...) – clemens Jan 24 '15 at 22:36 • no there will be more ocurrences – Arturo Jan 24 '15 at 22:37 ## 1 Answer Here's a slightly modified version of what you wrote: \documentclass{article} \usepackage{lmodern} \usepackage{listings,xcolor,etoolbox} \definecolor{verbgray}{gray}{0.9} \newcommand*\prompt{}% empty default \lstnewenvironment{sh}{% % redefine bash prompt: \def\prompt{user@linux:\textasciitilde\$\space}%
\lstset{backgroundcolor=\color{verbgray},
frame=single,
framerule=1pt,
basicstyle=\ttfamily,
columns=fullflexible,
escapechar=@
}%
}{}
% patch \lst@NewLine:
\makeatletter
\patchcmd\lst@NewLine
{\hbox{}}% search
{\hbox{}\prompt}% replace
{}% success
{}% failure
\makeatother
\begin{document}
\begin{sh}
@\textbf{date}@
Thu Oct 25 13:51:54 EDT 2007
\end{sh}
\end{document}


You need fonts which will allow bold when creating ttfamily. Hence the loading of

\usepackage{lmodern}

• why I don't see mine in bold? – Arturo Jan 24 '15 at 22:26
• @Arturo you need a monospaced font with a bold variant – clemens Jan 24 '15 at 22:33
