I would like to conditionally add text (for example, "- Answers") to my exercise sheet title based on the global solution/print option set in \xsimsetup.

My goal is to have the title change automatically when I toggle the option, without any manual edits. I have tried many conditionals in the documentation, such as \ExerciseParameterIfSetTF but couldn't manage to make it work. I think it just work inside exercise environment.

\documentclass{article} \usepackage{xsim} \xsimsetup{ solution/print = true } \begin{document} {\Huge My Awesome Exercise Sheet : \ExerciseParameterIfSetTF{solution}{print}{Answers}{ }} \begin{exercise}[title=First Question] What is the result of $2+2$? \end{exercise} \begin{solution} The result is $4$. \end{solution} \end{document}

The option solution/print is stored per exercise type, with the default type being exercise. There is an internal command \xsim_if_solution_print:nTF{exercise type}{true}{false} that queries the option for the specified exercise type. You can write a wrapper command around this internal command, with exercise as the first argument.

In the code below I used exercise as the default value for an optional argument to the wrapper command. If you have a different exercise type then you can use that optional argument with the name of the exercise type.

MWE:

\documentclass{article} \usepackage{xsim} \xsimsetup{ solution/print = true } \ExplSyntaxOn \NewDocumentCommand\IfPrintSolutions{O{exercise}mm}{% \xsim_if_solution_print:nTF {#1} {#2} {#3} } \ExplSyntaxOff \begin{document} {\LARGE My Awesome Exercise Sheet: \IfPrintSolutions{Answers}{No answers}} \begin{exercise}[title=First Question] What is the result of $2+2$? \IfPrintSolutions{Answer below}{Answer yourself} \end{exercise} \begin{solution} \IfPrintSolutions{This is the answer}{This is not the answer}: the result is $4$. \end{solution} \end{document}

Result:

text shown for print=true

  • Excellent, thank you very much. Is there an analogous command that is triggered based on the option exercise/print = true or false ? Commented Sep 24 at 13:28

    @AymaneFihadi not directly, but as an untested first guess you might be able to use \bool_if:cTF {l__xsim_exercise_exercise_print_bool}{true}{false} inside of \ExplSyntaxOn. Commented Sep 24 at 13:44
  • Thanks again \NewDocumentCommand\IfPrintExercises{mm}{ \bool_if:cTF {l__xsim_exercise_exercise_print_bool} {#1} {#2} works perfectly. I just don't know how to integrate the optional parameter for the exercise type. Commented Sep 24 at 14:15
  • @AymaneFihadi I think \NewDocumentCommand\IfPrintExercises{O{exercise}mm}{ \bool_if:cTF {l__xsim_#1_exercise_print_bool} {#2} {#3} may work for that. Commented Sep 24 at 17:47
