Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “In the previous chapter, we learned how to use if, if-else, else-if, switch, case, continue, break, and goto in Go.”

A block of code is set as follows:

package main
import "fmt"
func main() {
  fmt.Println(10 > 5)
  fmt.Println(10 == 5)
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

go doc -all

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

error, unexpected nil value

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “ Once done, select View from the top menu bar, then select Explorer.”
