Complete list of commonly used commands in Go

As a fast and reliable programming language, Go language has been widely praised and used. In daily development, it is very important to master some commonly used commands. This article will introduce some common commands in Go language and provide specific code examples to help readers better understand and use them.

1. go run

Use the go run command to run Go programs directly. Enter the following code example at the command line:

go run main.go

This will compile and run the Go program named main.go.

2. go build

The go build command is used to compile Go programs. Enter the following example command:

go build -o output main.go

This will compile a program named main.go and name the resulting executable file output.

3. go test

The go test command is used to run tests in Go programs. The following is a simple test example:

package main

import "testing"

func TestAdd(t *testing.T) {
    result := Add(2, 3)
    if result != 5 {
        t.Errorf("Expected 5, got %d", result)
    }
}

Use the go test command to run the test and output the results.

4. go get

go get -u github.com/gin-gonic/gin

This will obtain and install the gin framework package.

5. go mod

The go mod command is used to manage Go module dependencies. Initialize a Go module with the following command example:

go mod init mymodule

This will create a new Go module.

6. go fmt

The go fmt command is used to format Go code. For example, enter the following command example:

go fmt main.go

This will format the code in the main.go file.

7. go vet

The go vet command is used to statically analyze Go code. For example, enter the following command example:

go vet main.go

This will perform static analysis on the main.go file.

The above are some common commands and code examples of Go language. I hope it can help readers better use Go language for development. Keep learning and practicing, and you will become more proficient in this excellent programming language.
