Always resumed list does not always resume if invoked from within an environment
The resume
option is always local, i.e. only within the current group. Using a list within some environment and trying to resume the list in another environment later on will fail in the sense that the information is lost.
The remedy is resume*
, which must be specified locally, however and can't be given as option to the \setlist
macro.
\documentclass{article}
\usepackage{enumitem}
\usepackage{xcolor}
\newlist{MyList}{enumerate}{2}
\setlist[MyList,1]{label={\arabic*.},resume}% ALWAYS resumed
\setlist[MyList,2]{label={\alph*)}}% NOT resumed
\newenvironment{MyColoredList}[2][]{%
\color{#2}%
\MyList[#1]
}{%
\endMyList%
}%
\begin{document}
\begin{MyColoredList}{red}
\item First Item
\end{MyColoredList}
Some text
\begin{MyColoredList}[resume*]{orange}% <--- This should be number 2
\item First Item
\end{MyColoredList}
Some text
\begin{MyList}% <--- This should be number 3
\item Second Item
\end{MyList}
Some text
\begin{MyList}
\item Third Item
\end{MyList}
Some text
\begin{MyColoredList}{blue}
\item Fourth Item (this works!!)
\begin{MyList}[resume*]
\item Inner Item
\end{MyList}
\end{MyColoredList}
\begin{MyColoredList}{violet}
\item Fifth Item (this works!!)
\begin{MyList}[resume*]
\item Inner Item
\end{MyList}
\end{MyColoredList}
\end{document}
A better way can be achieved with the series=
key:
\documentclass{article}
\usepackage{enumitem}
\usepackage{xcolor}
\newlist{MyList}{enumerate}{2}
\setlist[MyList,1]{label={\arabic*.},resume=foo}% ALWAYS resumed
\setlist[MyList,2]{label={\alph*)}}% NOT resumed
\newenvironment{MyColoredList}[2][]{%
\color{#2}%
\begin{MyList}[#1]
}{%
\end{MyList}%
}%
\begin{document}
\begin{MyColoredList}[series=foo]{red}
\item First Item
\end{MyColoredList}
Some text
\begin{MyColoredList}{orange}% <--- This should be number 2
\item First Item
\end{MyColoredList}
Some text
\begin{MyList}% <--- This should be number 3
\item Second Item
\end{MyList}
Some text
\begin{MyList}
\item Third Item
\end{MyList}
Some text
\begin{MyColoredList}{blue}
\item Fourth Item (this works!!)
\begin{MyList}[resume*]
\item Inner Item
\end{MyList}
\end{MyColoredList}
\begin{MyColoredList}{violet}
\item Fifth Item (this works!!)
\begin{MyList}[resume*]
\item Inner Item
\end{MyList}
\end{MyColoredList}
\end{document}
You can do it the hard way:
\documentclass{article}
\usepackage{enumitem}
\usepackage{xcolor}
\newlist{MyList}{enumerate}{2}
\setlist[MyList,1]{
label=\arabic*.,
before=\setcounter{MyListi}{\value{MyList}},
after=\setcounter{MyList}{\value{MyListi}},
}% ALWAYS resumed
\setlist[MyList,2]{label=\alph*)}% NOT resumed
\newcounter{MyList}
\newenvironment{MyColoredList}[2][]{%
\color{#2}\begin{MyList}[#1]
}{%
\end{MyList}%
}%
\begin{document}
\begin{MyColoredList}{red}
\item First Item
\end{MyColoredList}
Some text
\begin{MyColoredList}{orange}% <--- This should be number 2
\item First Item
\end{MyColoredList}
Some text
\begin{MyList}% <--- This should be number 3
\item Second Item
\end{MyList}
Some text
\begin{MyList}
\item Third Item
\end{MyList}
Some text
\begin{MyColoredList}{blue}
\item Fourth Item (this works!!)
\end{MyColoredList}
\end{document}
You can try this
\documentclass{article}
\usepackage{enumitem}
\usepackage{xcolor}
\makeatletter
\newlist{MyList}{enumerate}{2}
\setlist[MyList,1]{label={\arabic*.},
after={\xdef\enit@resume@MyList{\noexpand\c@MyListi=\the\c@MyListi}},resume}% ALWAYS resumed
\setlist[MyList,2]{label={\alph*)}}% NOT resumed
\makeatother
\newenvironment{MyColoredList}[2][]{%
\color{#2}%
\begin{MyList}[#1]
}{%
\end{MyList}%
}%
\begin{document}
\begin{MyColoredList}{red}
\item First Item
\end{MyColoredList}
Some text
\begin{MyColoredList}{orange}% <--- This should be number 2
\item First Item
\end{MyColoredList}
Some text
\begin{MyList}% <--- This should be number 3
\item Second Item
\end{MyList}
Some text
\begin{MyList}
\item Third Item
\end{MyList}
Some text
\begin{MyColoredList}{blue}
\item Fourth Item (this works!!)
\end{MyColoredList}
\end{document}
