Tagging and new environment

Question

I am using the tagging package in my document to "customize it. To include/exclude some parts of my document using a taglist, I could use the following : \begin{taggedblock}{<taglist>} and \end{taggedblock}. But I wanted to include this into a new environment (which is more complicated than the example which follows) so here is what I did :

\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\usepackage{tagging}

\newenvironment{myenvironment}[1]{\begin{taggedblock}{#1}}{\end{taggedblock}}

\usetag{1}

\begin{document}

\begin{myenvironment}{1,2}
test 1,2
\end{myenvironment}

\begin{myenvironment}{2}
test 2
\end{myenvironment}

\end{document}

But this example produces an error. From what I understand, the problem is this one : the way I defined myenvironment, it does not accept lists of tags. If I replace my second block with \begin{myenvironment}{1,2} test 2 \end{myenvironment} then there is no problem when I compile the document. How could I modify this environment to accept a list of tags ?

Answer 1

If you define your environment as

\newenvironment{myenvironment}[1]{\taggedblock{#1}}{\endtaggedblock}

then things work:

Note:

• I have seen this trick used when wrapping environment around tabular but not sure why it is needed.

Code:

\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\usepackage{tagging}

\newenvironment{myenvironment}[1]{\taggedblock{#1}}{\endtaggedblock}

\usetag{1}
%\droptag{2}

\begin{document}

\begin{myenvironment}{1,2}
test 1,2
\end{myenvironment}

\begin{myenvironment}{2}
test 2
\end{myenvironment}

\end{document}
