How to create two versions of a document?

Question

I've read similar questions, but my problem seems to require a little more sophisticated solution.

I have some notes that I want as my lecture notes and as handouts. These two versions will have a different set of questions and answers. I'm using ExSheets package and tried to change the value of question/print option. (I don't really understand the differences between an option and a property. So at first I assumed that the option is just same as property.)

\documentclass {tufte-book}
\usepackage{exsheets}
\usepackage{ifthen}

\DeclareQuestionClass{user}{users}
\SetupExSheets{use-users={b,t}}
\def \forHandouts {true}

\begin{document}

\ifthenelse{\equal{\forHandouts}{true}} {
  \ForEachQuestion {
    \ifthenelse{\equal {\GetQuestionClass{user}}{t}}{
       \SetQuestionProperties{question/print = false}
       % \SetupExSheets{question/print = false} %this or the above
     }}}
\begin{question}[user=b] blah, blah...
\end{question}
\end{document}

Answer 1

You don't need any complicated conditionals. The “question class” concept and the option use-<classes>=... should actually suffice.

If I understand correctly in the handout version you only want to print questions with user=b while in the other version both user=b and user=t may be printed?

Then you can use \SetupExSheets{use-users={b}} in the handout version and \SetupExSheets{use-users={b,t}} in the other one. If you prefer a switch I'd use a simple \newif\ifhandout and make the setup dependent on it's setting:

\documentclass {tufte-book}

\usepackage{exsheets}
\DeclareQuestionClass{user}{users}

% new switch:
\newif\ifhandout

% set the switch:
\handoutfalse
% \handouttrue

\ifhandout
  \SetupExSheets{use-users={b}}
\else
  \SetupExSheets{use-users={b,t}}
\fi

\begin{document}

\begin{question}[user=b]
  I'm in both versions
\end{question}
\begin{question}[user=t]
  I'm not in the handout version
\end{question}

\end{document}

---

Reading the comments you probably want something else. The following defines a new question/solution pair lecture/lecturesol which has the default option print=false if the handout switch is set to true so the corresponding exercises only are printed in the lecture notes:

\documentclass {tufte-book}

\usepackage{exsheets}
% new switch:
\newif\ifhandout

% set the switch:
\handoutfalse % this is set by default but doesn't hurt to be set explicitly either
% \handouttrue

\ifhandout
  \NewQuSolPair{lecture}[print=false]{lecturesol}
\else
  \NewQuSolPair{lecture}{lecturesol}
\fi

\begin{document}

\section{Exercises}
\begin{question}
  I'm both in the lecture \emph{and} the handout version.
\end{question}
\begin{solution}
  Solution to exercise one.
\end{solution}

\begin{lecture}
  I'm only in the lecture version but not in the handout version.
\end{lecture}
\begin{lecturesol}
  Solution to exercise two.
\end{lecturesol}

\begin{question}
  I'm both in the lecture \emph{and} the handout version.
\end{question}
\begin{solution}
  Solution to exercise three.
\end{solution}

\begin{lecture}
  I'm only in the lecture version but not in the handout version.
\end{lecture}
\begin{lecturesol}
  Solution to exercise four.
\end{lecturesol}

\section{Solutions}
\printsolutions

\end{document}

With \handoutfalse:

With \handouttrue:

Trying to clear up the confusion: »properties« are not the same as options! Options usually are set up with \SetupExSheets or if necessary with the optional argument.

Properties either are set up automatically -- this is only true for some predefined properties like counter, subtitle or question-body -- or must be set explicitly with \SetQuestionProperties in the question body of the corresponding question.
