Vbar and Rbar don't work with new lists

Nokel81 commented 4 years ago

The following small file fails to compile.

\documentclass{book}
\usepackage{enumitem}
\usepackage{etoolbox}
\usepackage[autocompile]{gregoriotex}

\newlist{alternate}{enumerate}{1}
\renewcommand\labelalternatei{\bfseries\protect\ifnumodd{\value{alternatei}}{\Vbar.}{\Rbar.}}

\begin{document}

Some text some text some text some text some text some text some text some text some text some text some text some text some text.
\begin{alternate}[wide=0pt]
  \item First
  \item Second
  \item Third
  \item Fourth
  \item Fifth
  \item Sixth
\end{alternate}

\end{document}

With the following error: ! Use of \\alternate doesn't match its definition..

However, if you change the \renewcommand... to ...{V.}{R.}} then it does compile.

I think \Vbar et al. are fragile commands. Try adding \protect in front of them in the original definition of your list.
