Learning Go Programming

Chapter 2. Go Language Essentials

In the previous chapter, we established the elemental characteristics that make Go a great language with which to create modern system programs. In this chapter, we dig deeper into the language's syntax to explore its components and features.

We will cover the following topics:

  • The Go source file
  • Identifiers
  • Variables
  • Constants
  • Operators

The Go source file

We have seen, in Chapter 1, A First Step in Go, some examples of Go programs. In this section, we will examine the Go source file. Let us consider the following source code file (which prints "Hello World" greetings in different languages):

The Go source file

golang.fyi/ch02/helloworld2.go

A typical Go source file, such as the one listed earlier, can be divided into three main sections, illustrated as follows:

  • The Package Clause:
          //1 Package Clause 
      package main
  • The Import Declaration:
          //2 Import Declaration 
      import "fmt" 
      import "math/rand" 
      import "time"
  • The Source Body:
          //3 Source Body 
      var greetings = [][]string{ 
        {"Hello, World!","English"}, 
        ... 
      } 
 
      func greeting() [] string { 
        ... 
      } 
 
      func main() { 
        ... 
      }

The package clause indicates the name of the package this source file belongs to (see Chapter 6, Go Packages...

Go identifiers

Go identifiers are used to name program elements including packages, variables, functions, and types. The following summarizes some attributes about identifiers in Go:

  • Identifiers support the Unicode character set
  • The first position of an identifier must be a letter or an underscore
  • Idiomatic Go favors mixed caps (camel case) naming
  • Package-level identifiers must be unique across a given package
  • Identifiers must be unique within a code block (functions, control statements)

The blank identifier

The Go compiler is particularly strict about the use of declared identifiers for variables or packages. The basic rule is: you declare it, you must use it. If you attempt to compile code with unused identifiers such as variables or named packages, the compilers will not be pleased and will fail compilation.

Go allows you to turn off this behavior using the blank identifier, represented by the _ (underscore) character. Any declaration or assignment that uses the blank identifier is not bound...

Go variables

Go is a strictly typed language, which implies that all variables are named elements that are bound to both a value and a type. As you will see, the simplicity and flexibility of its syntax make declaring and initializing variables in Go feel more like a dynamically-typed language.

Variable declaration

Before you can use a variable in Go, it must be declared with a named identifier for future reference in the code. The long form of a variable declaration in Go follows the format shown here:

var <identifier list> <type>

The var keyword is used to declare one or more variable identifiers followed by the type of the variables. The following source code snippet shows an abbreviated program with several variables declared outside of the function main():

package main 
 
import "fmt" 
 
var name, desc string 
var radius int32 
var mass float64 
var active bool 
var satellites []string 
 
func main() { 
  name = "Sun" 
  desc = "Star" 
  radius...

Go constants

In Go, a constant is a value with a literal representation such as a string of text, Boolean, or numbers. The value for a constant is static and cannot be changed after initial assignment. While the concept they represent is simple, constants, however, have some interesting properties that make them useful, especially when working with numeric values.

Constant literals

Constants are values that can be represented by a text literal in the language. One of the most interesting properties of constants is that their literal representations can either be treated as typed or untyped values. Unlike variables, which are intrinsically bound to a type, constants can be stored as untyped values in memory space. Without that type constraint, numeric constant values, for instance, can be stored with great precision.

The followings are examples of valid constant literal values that can be expressed in Go:

"Mastering Go" 
'G' 
false 
111009 
2.71828 
94314483457513374347558557572455574926671352...

      import "math/rand" 
      import "time"

          //3 Source Body 
      var greetings = [][]string{ 
        {"Hello, World!","English"}, 
        ... 
      } 
 
      func greeting() [] string { 
        ... 
      } 
 
      func main() {

Vladimir Vivien's Learn Go Programming is a timely and practical hands-on guide to accelerate your learning curve with Google's fast growing program. Go is know for its ability to handle large, complex software in a team environment. Vladimir provides sample code, tips and warnings to help programmers at all levels avoid pitfalls. As a former IBM principal & E&Y consultant working with multinational corporations, I appreciate the value of what Vivien's Learn Go Programming can bring to individuals and large enterprise teams. Finally, as Director of Analytics and Continuous Improvement I see how Go plays a vital role for writing the code to manage complex server networks, needed to handle #big data, #machine learning and #IoT. I give Mr Vivien's Learn Go my highest recommendation

I own dozens of programming language books and i have been programming for 24 years. This is one of the best introductory books i own on learning a new programming language, and the best, hands down, on the GO programming Language.If you want to learn programming in this powerful and wonderful language and you are already familiar with programming you must read this book first, the author is honest with his words, he wishes he had such a book when he begun learning GO, i wish the same!

Good book overall. Straight forward, easy examples. My one issue is that it is literally riddled with typos and small code errors. I could tell based on previous programming experience where they were but if I didn't have the experience it could be very confusing

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.
