xsim and beamer about xsim

[romildo]

I would like to use xsim to write slides for programming classes with practices, where I intersperse explanatory material, examples, and tasks (exercises).

[cgnieder]

Add \newcounter{paragraph} and use \begin{frame}[fragile] ... \end{frame}.

I must say I am quite surprised by this use of xsim. It aims at creating exercise sheets or exercises with solutions in books, maybe also for creating exams. But I never anticipated that it might be used in presentations… o.O

hello @romildo,
https://tex.stackexchange.com/questions/187905/beamer-exsheets-package
just add
\let\solution\relax
thanks you

[ptoche]

just for your information Clemens, my use case is an in-class test where the questions are projected on screen and not printed on paper: Since I have an extended database of questions, it makes sense to use xsim. And while it would be reasonably easy to use the article class with a custom geometry to mimic the effect of beamer, well it's natural to want to use beamer. :-)

Just add \newcounter{paragraph} with what you do @romildo .
You need to defined a new \DeclareExerciseType to have the headings. (There is a good one with tcolorbox).

MWE :

\documentclass[12pt,aspectratio=1610]{beamer}%Information to be included in the title page:
\makeatletter
\@ifclassloaded{beamer}{%
  %%% save beamer's `solution' environment as `beamersolution':
  \let\beamersolution\solution
  \let\endbeamersolution\endsolution
  %%% "delete" the `solution' environment:
