Hands-On Go Programming

By: Tarik Guney

Overview of this book

<p>With its C-like speed, simplicity, and power for a growing number of system-level programming domains, Go has become increasingly popular among programmers. Hands-On Go Programming teaches you the Go programming by solving commonly faced problems with the help of recipes. You will start by installing Go binaries and get familiar with the tools used for developing an application. Once you have understood these tasks, you will be able to manipulate strings and use them in built-in function constructs to create a complex value from two floating-point values. You will discover how to perform an arithmetic operation date and time, along with parsing them from string values. In addition to this, you will cover concurrency in Go, performing various web programming tasks, implementing system programming, reading and writing files, and honing many fundamental Go programming skills such as proper error handling and logging, among others. Whether you are an expert programmer or newbie, this book helps you understand how various answers are programmed in the Go language.</p>

Finding today's date and time


In this section, we are going to learn how to find today's date and time. We can use time.Now to get today's date, and it imports a time package, and time returns a time type, and so we are going to assign this to another variable and use the String function. The following code will help you understand better:

package main

import (
  "time"
  "fmt"
)

func main(){
  current := time.Now()
  fmt.Println(current.String())
}

The output for the preceding code is as follows:

As you can see, we get a big string here that has everything, and we can, of course, format that to our needs. For instance, I can add the current.Format function and a predefined layout as seen in the following screenshot:

package main

import (
 "time"
 "fmt"
)

func main(){
 current := time.Now()
 fmt.Println(current.String())

 fmt.Println("MM-DD-YYYY :", current.Format("01-02-2006"))
}

The output to the code shown in the preceding screenshot is as follows:

 

In the previous screenshot, you will...
