Page Layout ⇒ Problem with new custom List Environment

[ghodsi]

Dear All,

I would like to write a list environment that only writes the non-empty items, but with the same label that would have appeared if that item was non-empty.

This is what I have:

Code: Select all

\documentclass{book}

\newcounter{mnum}
\newenvironment{mlist}{\setcounter{mnum}{0}     % 1) 2) 3)
\begin{list}{\thechapter.\arabic{mnum})}{\usecounter{mnum}\rightmargin=6mm
    \labelwidth=7mm\labelsep=2mm\setlength{\parsep}{\parskip}
    \setlength{\listparindent}{\parindent}
    \partopsep=0cm}}{\end{list}}
    
\begin{document}
\chapter{Test}
\begin{mlist}
\item
\item second item second item second item second item second item second item second item second item second item second item 
\item third
\item
\item fifth
\item
\item
\item eight
\item
\end{mlist}
\end{document}

I would like to have a new list environment that typeset something like the following animation does:

\documentclass{book}
\begin{document}
\noindent 	I want it to automatically generate this:
\begin{description}
\itemsep=0in
\item[\normalfont 1.2)] second item second item second item second item second item second item second item second item second item second item 
item[\normalfont 1.3)] third
\item[\normalfont 1.5)] fifth
\item[\normalfont 1.8)] eight
\end{description}                                                        	          	                
\end{document}

I would appreciate your help.

If you don't mind to use a different name than \item and put curly braces around the items, this would be quite simple:

Code: Select all

\documentclass{article}
\usepackage{ifthen}

\newcommand{\oitem}[1]
           {\ifthenelse%
             {\equal{#1}{}}%
             {\stepcounter{enumi}}%
             {\item#1}%
           }

\begin{document}
  \begin{enumerate}
    \oitem{first}
    \oitem{}
    \oitem{}
    \oitem{fourth}
    \oitem{}
  \end{enumerate}
\end{document}
