# enumerate custom label

I writting a project documentation with LaTeX. I am doing the user requeriments and the structure that I want to put in the documents is something like this:

UR-1: The client ...
UR-2: ...
UR-3: ...


I've create an enumerate list like this:

\begin{enumerate}
\item The client
\end{enumerate}


but this only put the number and the text. How I can put the label "UR-" before the number in all the enumerate?

This question came from our site for professional and enthusiast programmers.

You can also use the optional parameter \item [UR-1], etc.. –  Peter Grill Nov 2 '12 at 20:48

With enumitem package you can create your own enumeration using \newList, where you can define view of it and then use it instead of default enumeration:

\documentclass{article}

\usepackage{enumitem}

\newlist{UR}{enumerate}{1}
\setlist[UR]{label=UR-\arabic*:}

\begin{document}
\begin{UR}
\item First
\item Second
\end{UR}
\end{document}

Hello I think the solution is good, but this doesn't work to me. I use a preamble where I put \usepackage{enumitem} \newlist{UR}{enumerate}{1} \setlist[UR]{label=UR-\arabic*:} and then I use the other part, but this can't work. Thanks for the response but I think I don't have the package enumitem. I'm using Fedora –  Juanma Jurado Nov 2 '12 at 16:25
Are you using \begin{UR} instead of \begin{enumerate} after adding this preamble? Could you send fragment of code? –  kpater87 Nov 2 '12 at 16:33
I think that the problem is that I can't use \userpackage{enumitem}. This give me an error. It's problem of my texlive package in Fedora. I'll search a solution. –  Juanma Jurado Nov 2 '12 at 17:16
How to force a newline after the UR-*? –  ziyuang Oct 28 '14 at 16:48
