[Tex/LaTex] Enumitem: Restart/Reset counter of new list

Question

I use the enumitem package to manipulate the appearance of my list. Because I want to keep the default enumerate list, I defined a new list edulist and configured it.

The list should be used in an environment edulistvar, which gives the user the ability to change the itemsep with an optional argument.

I want this list to resume until several points in my document are reached (see \exercise in the example below). Resetting the counter of the list I want to do with \restartlist<list-name>} which seems to exist exact for this reason:

enumitem documentation

Currently, with

\setlist[enumerate]{resume}

you can get a continuous numbering through a document.A new command
has been added for restarting the counter in the middle of the
document:

\restartlist{<list-name>}

It is based solely in the list name, not the list type, which means
enumerate* as defined with the package option inline is not the same
as enumerate, because its name is different.

Unfortunately, I don't get it work in the following MWE.

Code

\documentclass{scrartcl}

\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{enumitem}
\usepackage{xparse}

\DeclareDocumentEnvironment {edulistvar} { O{0pt} } {
  \begin{edulist}[itemsep=#1]
}{
  \end{edulist}
}

\DeclareDocumentCommand \exercise {  } {%
  \bigskip
  \textsf{\bfseries\Large Exercise}
  \medskip
  \par
  \restartlist{edulist}
}


\newlist{edulist}{enumerate}{1}

\setlist[edulist]{%
  label=\alph*),    
  format=\sffamily,
  resume=edulist,
  partopsep=0ex,
  topsep=0.5\baselineskip,
  parsep=\parskip,
}

\begin{document}

\exercise

Bli Bla Blub

\begin{edulist}
  \item One
  \item Two
  \item Three
\end{edulist}

Bli Bla Blub

\begin{edulist}
  \item One
  \item Two
  \item Three
\end{edulist}

\exercise

Bli Bla Blub

\begin{edulistvar}[\baselineskip]
  \item One
  \item Two
  \item Three
\end{edulistvar}

\end{document}

Any idea how to reset the counter of the list? Manually resetting it (\setcounter{edulisti}{0}) doesn't work, as well.

Answer 1

I'm not sure I understand your question, either, but it seems straightforward to modify the MWE to do what you appear to want, if I've understood correctly, without the need for intervention by the end user:

\documentclass{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{enumitem}
\usepackage{xparse}

\DeclareDocumentEnvironment {edulistvar} { O{0pt} } {
  \begin{edulist}[itemsep=#1, resume=edulist]
}{
  \end{edulist}
}

\DeclareDocumentCommand \exercise {  } {%
  \bigskip
  \textsf{\bfseries\Large Exercise}
  \medskip
  \par
  \restartlist{edulist}
}


\newlist{edulist}{enumerate}{1}

\setlist[edulist]{%
  label=\alph*),
  format=\sffamily,
  partopsep=0ex,
  topsep=0.5\baselineskip,
  parsep=\parskip,
  resume}

\begin{document}

\exercise

Bli Bla Blub

\begin{edulist}
  \item One
  \item Two
  \item Three
\end{edulist}

Bli Bla Blub

\begin{edulist}
  \item One
  \item Two
  \item Three
\end{edulist}

\exercise

Bli Bla Blub

\begin{edulistvar}[\baselineskip]
  \item One
  \item Two
  \item Three
\end{edulistvar}

\begin{edulistvar}[\baselineskip]
  \item One
  \item Two
  \item Three
\end{edulistvar}

\end{document}
