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: "You will notice that the deployable artifact for your application is the webApp.war file."

A block of code is set as follows:

package meander
type Cost int8
const (
  _ Cost = iota
  Cost1
  Cost2
  Cost3
  Cost4
  Cost5
)

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

go build -o project && ./project

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: "Once you install Xcode, you open Preferences and navigate to the Downloads section"
