Text Formatting ⇒ How to number definitions ... ?

[helllo]

Hi everyone ,
I've got a quick question :
I don't have numbers with my definitions using this :

Code: Select all

\newenvironment{definition}[1][Definition]{\begin{trivlist}

Do you know how to change it so I can get numbered definitions ?
Thanks !

You don't have anything at all using that. By now, you should be well acquainted with Board Rules.

However, why not using amsmath's theorem? E.g.:

Code: Select all

\documentclass{article}

\usepackage{lipsum}% just to generate some dummy text

\usepackage{amsmath}

\newtheorem{definition}{Definition}
\newcommand{\mydef}[1]{\begin{definition}#1\end{definition}}

\begin{document}

\section{A section}

\begin{definition}
\lipsum[1]
\end{definition}

\mydef{\lipsum[2]} 

\section{Another section}

\mydef{\lipsum[3]}

\end{document}

More infos and how to do further customizations can be found here.

Hi,
I don't have the "lipsum" package, but the rest worked!
Thanks
