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: "However, declaring libraries in project.clj is much simpler than doing it in the pom.xml file of Maven."

A block of code is set as follows:

String str = "Hello ".concat("world !");

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

$ mv lein ~/bin

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Go to the Data Buckets tab and click on the Create New Data Bucket option."
