Learn indentation techniques in Go language from examples

Go language is a concurrency-oriented programming language with the characteristics of simplicity and efficiency, and good code indentation style is a very important part when writing Go programs. In the Go language, indentation is usually done using a tab or a certain number of spaces. In general, Go officially recommends using 4 spaces as indentation. This article will introduce common indentation techniques in Go language through examples, so that readers can better master this technology.

1. Basic indentation skills:

In Go language, indentation is usually used to indicate the scope of code blocks, such as after keywords such as if, for, func, etc. The code segment belongs to the code block of the statement and needs to be indented to distinguish the code level.

package main

import "fmt"

func main() {
    for i := 0; i < 10; i++ {
        if i%2 == 0 {
            fmt.Println(i, "是偶数")
        } else {
            fmt.Println(i, "是奇数")
        }
    }
}

In the above example, you can see that the code blocks after the if statement and the for statement are properly indented, and the code structure is clear and easy to read and understand.

2. Indentation skills for multi-line code:

When a line of code is too long and needs to be wrapped, you can use indentation to keep the code tidy. Generally speaking, new The start of a line of code should be aligned with the end of the current line.

package main

import "fmt"

func main() {
    message := "这是一个非常长的字符串，需要换行才能完整显示出来，这时候可以使用缩进来对齐。"
    fmt.Println(message)
}

In the above example, the message string is longer. For the beauty and readability of the code, we use indentation to align the new line of code.

3. Indentation tips for structures and methods:

In Go language, structures and methods are usually defined together. In order to make the code look clearer, we You can use indentation to align methods within a structure.

package main

import "fmt"

type Person struct {
    Name string
    Age int
}

func (p Person) PrintInfo() {
    fmt.Println("姓名：", p.Name)
    fmt.Println("年龄：", p.Age)
}

In the above example, the PrintInfo method uses indentation alignment to make it readable with the definition of the Person structure, making it easier to read the code structure.

Through the above examples, readers can better understand the techniques of using indentation in the Go language. Reasonable indentation can improve the readability and maintainability of the code. It is recommended to develop good habits when writing Go programs. Indentation habits.
