The preferred language for cross-platform development: Practical experience in learning Go language

With the continuous development of Internet technology, cross-platform development has become more and more common and important. When choosing a programming language suitable for cross-platform development, people often consider factors such as ease of learning, stability, and performance. The Go language has become the first choice of many developers because of its simplicity, efficiency and cross-platform development advantages.

Go language is developed by Google and has obvious advantages in cross-platform development. First of all, the Go language compiler can directly compile source code into machine code without relying on a virtual machine or interpreter. This allows the Go language to run on different operating systems and platforms, including Linux, Windows and Mac OS.

Secondly, the Go language provides a rich standard library, covering various fields such as network programming, concurrent programming, and file operations. These standard libraries provide great convenience in cross-platform development. Developers can directly use these libraries to implement cross-platform functions.

Below, we will learn the cross-platform development of Go language through practical experience. First, we need to install the Go language development environment. You can visit the official website (https://golang.org/) to download the installation package suitable for your operating system and follow the prompts to install it.

After the installation is complete, we can write a simple cross-platform program to verify the cross-platform nature of the Go language. The following is a sample program:

package main

import (
    "fmt"
    "runtime"
)

func main() {
    fmt.Printf("当前操作系统：%s
", runtime.GOOS)
    fmt.Printf("当前架构：%s
", runtime.GOARCH)
}

In this sample program, we use the runtime package of the Go language to obtain the current operating system and architecture information, and then pass fmtPackage is printed. Next, we can try running this program on different operating systems.

Enter the directory where the program is located at the command line and execute the following command to compile and run the program:

go build main.go
./main

On Linux and Mac OS, you will get output similar to the following:

当前操作系统：linux
当前架构：amd64

On Windows, you will get output similar to the following:

当前操作系统：windows
当前架构：amd64

As you can see, through the runtime package of the Go language, we can easily obtain and print out the current Operating system and architecture information. This demonstrates the advantages of cross-platform development.

Of course, the cross-platform development of Go language is not limited to simple functions such as obtaining operating system and architecture information. In fact, we can use Go language to develop various types of applications, including web applications, command line tools, and desktop applications.

When developing cross-platform web applications, we can use the net/http package of the Go language to handle HTTP requests and responses. This package provides functionality to develop web servers and clients and can be easily deployed and run on different operating systems.

When developing cross-platform command line tools, we can use the os and bufio packages of the Go language to process command line parameters and user input and output. These packages provide rich functionality and easy-to-use APIs, allowing developers to easily implement cross-platform command line tools.

When developing cross-platform desktop applications, we can use third-party libraries of Go language, such as fyne and qt, etc. These libraries provide rich interface components and event handling mechanisms, allowing developers to quickly build cross-platform desktop applications and run them on different operating systems.

To sum up, Go language, as a preferred language for cross-platform development, has the advantages of ease of learning, stability and high performance. Through learning from practical experience, we can not only understand the cross-platform features of the Go language, but also master its applications in different fields. I believe that through learning and practice, you will discover the convenience and efficiency that Go language brings to cross-platform development.
