tcolorbox dispExample in Beamer

Question

I used the @egreg's answer in beamer, but it doesn't work. How to handle it?

Answer 1

You need the fragile frame option if your frame contains something fragile like a lstlisting.

(and don't forget to compile with shell-escape enabled)

% !TeX program = txs:///arara
% arara: pdflatex: {synctex: on, interaction: nonstopmode, shell: yes}
\documentclass{beamer}
\usepackage[all]{tcolorbox}
\setbeamertemplate{background canvas}{\includegraphics[height=\paperheight]{example-image-duck}}
\tcbset{
  boxrule=0pt,
  opacityfill=0,
  listing engine=minted,
  docexample/.add style={}{
    fontlower=\normalsize,
    minted language=latex, % <--------
    documentation minted options={
      autogobble=true,
      fontsize=\small,
      style=bw, % <-------
    }
  }
}
\begin{document}
\begin{frame}[fragile]
\begin{dispExample}
\begin{equation}
  \int_{-\infty}^{\infty} \exp (-x^2) , dx = \sqrt{\pi}
\end{equation}
\end{dispExample}
\end{frame}
\end{document}
