# ESDL Formatting (LaTeX)

Most publications in this field (and computer science more generally) are created using LaTeX. To simplify/assist/encourage the inclusion of ESDL in publications, this page provides settings for the listings package for an ESDL environment. At present, this is a little hacked together, but over time will be improved (feedback is very welcome). Anyone is welcome to freely use and/or modify these settings for their own purposes (no attribution required).

An example (click for larger image):

Listings are introduced using either of the following two lines, depending on whether line numbers are desired. I usually put listings within a \begin{minipage}{0.95\textwidth} or \begin{minipage}{\columnwidth}.

\begin{esdl}[label={label},caption={caption},style=nonumbers]}
\begin{esdl}[label={label},caption={caption},style=numbers]}


The definition below should be included in your preamble. It uses @ as a LaTeX escape, allowing labels and crossreferences in the listing.

\usepackage{listings}
