I have the following versions of the forest and etextools packages:

Package: forest 2015/07/15 v1.0.10 Drawing (linguistic) trees
Package: etextools 2010/12/07 v3.1415926 e-TeX more useful tools for LaTeX pack
age writers

When I try to compile the following MWE:

\documentclass{standalone}

\usepackage{forest}
\usepackage{etextools}

\begin{document}
  \begin{forest}
    [a [b] [c]] 
  \end{forest}
\end{document}

I get the following error:

! Argument of \ettl@forloop has an extra }.
<inserted text> 
                \par 
l.9   \end{forest}

The MWE works fine if I remove the etextools include. How can I use both at the same time?

  • No, you can't. The etextools package redefines several constructs in etoolbox in incompatible ways. Unfortunately, some of the commands introduced by etextools, which was based on the first version of etoolbox were later incorporated into the “parent” package, but the “child” package didn't acknowledge it. – egreg Nov 12 '15 at 09:37
  • @egreg Thanks, I can see now that it is a problem with etoolbox and etextools. I can hack a solution to get it working by forcing the etoolbox macro, but I guess I will have to start using something else in the future. – TonioElGringo Nov 12 '15 at 09:42
