I use the package "answers" in a Markdown file. After compilation with Pandoc the PDF I get is ok (solutions at the right place) but the option of the following LaTeX command \Optionsolutionfile{ans}[ex1] produces the writing of [ex1]. How to avoid that?

I precise that there are two series of exercises in my document and each series is followed by the solutions.

That's why I use \Optionsolutionfile{ans}[ex1] and then \Optionsolutionfile{ans}[ex2] at another place.

Thanks in advance

Pandoc doesn't like the option in brackets after the latex command. In order to make it work you have to use a recent version of pandoc that supports generic raw attributes. Now you can create a raw latex block around the offending command:


Or inline:

  • Thanks DG but it's not good. Which version of pandoc should I use ?

In fact it works even with pandoc old version (1.12 debian jessie)

In the file default.latex I've created a newcommand

\newcommand{\fic}[1]{ \Optionsolutionfile{ans}[ex#1] }

and inside my file.md I call the command by

\fic {1}

at the right place to get the solutions of the first serie of exercises and the

\fic {2}

to get the second serie of solutions etc...
