Hi i am trying to add an inline code block in a Latex document. I know how to add a separate code block using lstlisting but i want to instead add an inline code block. I am attaching the screenshot of output that i am expecting .As you can see in the same line a code block is added which contains the expression print(g). I want something like that. So that it should be customizable that is the background color of the box, width and height of the box, border width etc. Also the text of the code inside that inline code block should be customizable as well. Is there a way to achieve this in Latex? Below is the screenshot.

It is possible, and here is one way do it. (This code is an excerpt from a package I maintain and for some reason, realboxes must be loaded after xcolor whereas in my package, which loads several other packages, that is not the case and I'm not yet sure why.)

The background color is an argument to the \Colorbox command.

% !TEX program = lualatexmk
% !TEX encoding = UTF-8 Unicode

\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}
\usepackage{realboxes} % needed for \Colorbox

\definecolor{gsbggray}     {rgb}{0.90,0.90,0.90} % background gray
\definecolor{gsgray}       {rgb}{0.30,0.30,0.30} % gray
\definecolor{gsgreen}      {rgb}{0.00,0.60,0.00} % green

  • Can we add border width and color using this? This looks good . Thanks man.

    Not with listings unfortunately, but I've added a variant showing how to use the immensely powerful tcolorbox package. Commented Feb 15, 2021 at 14:01

Since you're familiar with the listings package and its lstlisting environment, you could use its \lstinline macro to typeset, well, an inline code block.

enter image description here

\documentclass{article}
\usepackage{listings} % for '\lstset' and '\lstinline' macros
% For this example, we use just a very basic set of arguments for \lstset:
\lstset{basicstyle=\ttfamily,keywordstyle=\underbar,morekeywords={print}}
\begin{document}
\sffamily\bfseries % just to mimic the OP's screenshot
The command \lstinline{print(g)} prints something.
\end{document}

  • Is it possible to add the kind of customization that i expect, using this macro? The background color and the border width and color? Thanks

    @JasonLiam - In my opinion, the listings package wisely doesn't provide too many options for decorating inline code, as otherwise pages quickly start to look like overly decorated, gaudy Christmas trees. Much too distracting, really. In particular, AFAICT, background color and framelines around inline code blocks are not supported. If you simply can't do without those questionable visual distractions, all I can suggest is that you look into the capabilities of the fancyvrb package.

  • I found another link to \colorbox macro. It seems to do the trick but still i don't think border width is possible using colorbox. I ll read more about it and your link as well.
