How to set up windows in golang

As a high-performance programming language, Golang has the advantages of fast compilation and efficient operation. When developing applications for the Windows platform, how to set up the Golang environment for better development and debugging? Next, we will introduce in detail how Golang sets up the Windows environment.

Step one: Install Golang

Visit Golang’s homepage (https://golang.org/) to download the corresponding Windows version, for example, the 1.15.3 version of the Windows installation package is named go1 .15.3.windows-amd64.msi.

Download and run the installation package and follow the prompts to install. After the installation is complete, you need to configure the environment variables and add the Go installation directory to the PATH variable. You can test whether the installation is successful by running the following command:

go version

After running this command, the version number of Go will be displayed, indicating that Golang is installed successfully.

Step 2: Set up the Golang development environment

1. Create a new project

Enter the development directory on the command line and execute the following command:

go mod init <projectname>

Among them, projectname is your project name. After executing the above command, a go.mod file will be generated for managing project dependencies.

2. Edit code

Use a text editor to open your Go code file and edit the corresponding code. For example, the following code:

package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello, Golang!")
}

Save the code file as main.go.

3. Compile and run

Enter the project directory in the command line and execute the following command:

go run main.go

After execution, Hello will be output in the command line , Golang!. If you want to generate a binary file, you can execute the following command:

go build

After execution, the generated executable file can be found in the project directory.

Step Three: Integrated Development Environment (IDE)

In addition to developing and compiling in the command line, you can also use the Integrated Development Environment (IDE) for development and debugging. The following recommends several commonly used Golang IDEs:

1. Visual Studio Code

Visual Studio Code is a free lightweight IDE launched by Microsoft. When using VS Code for Golang development, you can install plug-ins to support code syntax highlighting, code prompts, code verification and other functions.

2. GoLand

GoLand is a Go language IDE launched by JetBrains. It has rich functions and a good user experience. When developing Golang, you can use the tools provided by GoLand to quickly create projects, write code, debug, etc.

3. Sublime Text

Sublime Text is a lightweight text editor that can support Golang development by installing plug-ins. Compilation and running can be achieved by setting Golang's build system.

Step 4: Common commands

When developing Golang, we need to master some common commands, as shown below:

1. go mod tidy

When using third-party dependencies in the project, you can automatically identify and download the dependencies through the go mod tidy command.

2. go get

Use the go get command to download and install third-party dependencies.

3. go test

Use the go test command to run the test code.

4. go fmt

Use the go fmt command to format the code to make it beautiful and easy to read.

5. go vet

Use the go vet command to check for potential problems in your code.

Step 5: Summary

The above is how to set up Golang on the Windows platform. When developing Golang, you need to master Golang's syntax, common commands, and development tools so that you can better write high-quality Golang code. Through the above setting method, I hope it can help students who are developing Golang.
