Adding a highlight to \texttt blocks

Question

I'm trying the add a grey highlight to the \texttt command to essentially achieve the same effect as the code blocks on here.

This is something I attempted to do when I first started writing my current document. I don't remember how I got there but the renew command I wrote looks like this:

\definecolor{Light}{gray}{.90}
\sethlcolor{Light}

\renewcommand{\texttt}{\hl}

This gives me the grey highlight, but the font it no longer monospace.

Can anyone help me?

See this answer for verbatim mode, but it could be what you want — egreg, Jan 31 '12 at 19:10

You need to make a small tweak:

\let\OldTexttt\texttt
\renewcommand{\texttt}[1]{\OldTexttt{\hl{#1}}}

to get normal text \texttt{foo bar} normal text to yield:

Alternative Solution:

Note that the above solution will effect all uses of \texttt{}. If that is not desired, an alternative solution would be to define a custom macro:

\newcommand{\hltexttt}[1]{\texttt{\hl{#1}}}

and then use \hltexttt{} when you want both the \hl and \texttt effect.

Code:

\documentclass{article}
\usepackage{xcolor}
\usepackage{soul}
\definecolor{Light}{gray}{.90}
\sethlcolor{Light}
\let\OldTexttt\texttt
\renewcommand{\texttt}[1]{\OldTexttt{\hl{#1}}}% will affect all \texttt
%\newcommand{\hltexttt}[1]{\texttt{\hl{#1}}}% comment above \renewcommand if want this
\begin{document}
normal text \texttt{foo bar} normal text 
\end{document}

I like the alternative better than the main solution. – DrBeco Jun 30 '19 at 00:48
Please, what would be the modification in a Beamer document . – robintux Jan 01 '20 at 16:21
@robintux: AFAIK, this should work in Beamer. If not, please ask a new question and include a fully compilable MWE including \documentclass and the appropriate packages that sets up the problem. – Peter Grill Jan 02 '20 at 01:33
@robintux this question have some alternatives to using highlight in beamer, although scavi's answer is probably even better. – hlovdal Mar 10 '24 at 13:02

Peter Grill already provided a great answer. Just as an alternative, you can also achieve this using \colorbox or \fcolorbox. The letter additionally allows you to specify a border color:

Code:

\usepackage{xcolor}
\definecolor{codebg}{gray}{0.95}
\definecolor{codeframe}{gray}{0.8}
\newcommand{\inlinecode}[1]{\fcolorbox{codeframe}{codebg}{\small!\texttt{#1}!}}

normal text \inlinecode{foo bar} normal text
