How can I create numbered flashcards?

Question

I'm using the "flashcards" document class and I want to implement an automatic numbering in the front part, such that, for example, when I write:

\documentclass[avery5388,grid,frame]{flashcards}
\cardfrontstyle[\large\slshape]{headings}

\begin{document}
\begin{flashcard}[Definition]{Something}
   Text
\end{flashcard}
\end{document}

it gets rendered to "Definition (i)", where "i" is the flashcard's number in the document. For now I tried to create a custom counter, and manually writing the code to show it inside the [Definition] part of the flashcard's command, but it is unpractical in the long run. Is there a better way to do it?

Answer 1

A way with tcolorbox and its tcbraster environment, there is no direct connection to printer labels producers like Avery etc, the specification has to be done manually.

The auto counter provides a new counter, here named 'flashcard' (well, hidden in a complex internal name) and \thetcbcounter is a wrapper for \the... macro connected to the counter.

I chose some of the most frequently used tcolorbox options which are pretty easy to remember and are very clear in their meanings (in my opinion)

\documentclass{article}

\usepackage[margin=1cm]{geometry}

%[avery5388,grid,frame]{flashcards}
%\cardfrontstyle[\large\slshape]{headings}

\usepackage[most]{tcolorbox}

\usepackage{blindtext}


\newtcolorbox[auto counter]{flashcard}[1][]{enhanced,
 title={Definition \thetcbcounter},
 sharp corners,
 boxrule=0.5pt,
 height=5cm,
 coltitle=black,
 colback=white, 
 colbacktitle=yellow,
 #1}

\begin{document}
\begin{tcbraster}[raster columns=4,raster equal height]
\begin{flashcard}
   Text
\end{flashcard}
\begin{flashcard}
\end{flashcard}
\begin{flashcard}
\end{flashcard}
\begin{flashcard}
\end{flashcard}
\end{tcbraster}
\end{document}
