Golang common style settings

As Golang continues to develop, more and more developers are starting to use it to build efficient and maintainable applications. However, in order to make the code easy to read, understand, and facilitate later maintenance, it is recommended that developers use Golang's commonly used coding style to write. This article will introduce the commonly used style settings in Golang.

1. Naming convention

In Golang, variable names, function names, constant names, structure names, etc. all need to follow certain naming conventions. The following are some common naming conventions:

• Use camel case naming: the first letter is lowercase, and the first letter of each word is capitalized, for example: firstName, lastName.
• The names of public variables or functions should start with a capital letter, such as: UserInfo, GetUserInfo().
• Avoid using single characters or abbreviations unless their meaning is very clear.

2. Code indentation

In Golang, indentation is very important. Use the tab key or 4 spaces to indent. Use a tab key or 4 spaces at the beginning of a code block to make it more readable. For example:

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

3. Comments

Comments are essential. In Golang, single-line comments start with //, and multi-line comments use /* */. Comments can help us better understand the function and details of the code. When writing comments, you should consider the following points:

• Provide a suitable explanation of the code and explain the role and function of the code.
• Explain variables and functions.
• Write down less obvious coding tips in your code for other developers to review.

4. Variable declaration

In Golang, variables need to be used through declaration. The following are some common variable declaration styles:

• When declaring a variable, put the variable type after the variable name, for example: var name string.
• If a variable needs to be initialized, it can be initialized when it is declared, for example: var name string = "John".
• Golang also provides a short variable declaration method :=, which can automatically infer the variable type, for example: name := "John".

5. Function declaration

In Golang, functions can receive multiple parameters and return multiple values. Here are some common function declaration styles:

• Use meaningful function names so that other developers can understand their purpose.
• Ensure that the function's parameters and return value have type declarations so that other developers can use the function correctly.
• If the function has multiple return values, the return value type needs to be added when declaring.

6. Code formatting

When writing code, you need to always pay attention to the formatting of the code. A good habit is to use a code formatting tool to format your code after you write it. This makes the code consistent, readable, and easy to maintain.

Summary

This article introduces some commonly used coding styles in Golang, including naming conventions, code indentation, comments, variable and function declarations, and code formatting. Through these specifications, more efficient, better readable, and easier to maintain code can be written, thereby improving development efficiency. Of course, these are just some suggestions, and developers can make adjustments based on actual development needs.
