Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Before you go to the Groovy documentation for MarkupBuilder to look for the book, author, and surname methods in MarkupBuilder, let me save you the effort."

A block of code is set as follows:

<?xml version="1.0"?>
<book>
   <author>
              <first_name>Fergal</first_name>
              <surname> Dearle</surname>
   </author>
   <title>Groovy for DSL</title>
</book>

Any command-line input or output is written as follows:

Hello, World!
Goodbye, World!
