golang annotation template

Golang is one of the most widely used programming languages ​​in the Internet industry today. It has the characteristics of efficiency, simplicity, and security, which makes it the first choice language for many developers. In the development process using Golang, comments are one of the essential elements. It can help us better understand the code and facilitate future maintenance and expansion. This article will introduce Golang comment templates to help developers write better comments and improve code readability.

1. The role of comments

Comments are text used in the program to explain and illustrate the code. When writing code, good comments can help make the code easier to read and understand. Comments can help other developers quickly understand important information such as code functions, implementation details, input and output, and can also help with code maintenance and updates.

2. Introduction to comment templates

1. File header comment template

At the top of the Golang code file, it is usually necessary to add file header comments to explain the basic information and author information. For example:

/**
 * @file   MyFile.go
 * @author John
 * @brief  This file is used for xxx
 */

 package main // 代码实现

Among them, the @file field is used to specify the file name, the @author field is used to specify the author of the file, @brief Field used to specify an overview of the file.

2. Function comment template

In Golang code, functions are an important way of organizing code, so it is necessary to add comments to each function to explain function functions, input and output and other information. . For example:

/**
 * @brief     This function is used to xxx
 * @param[in] a, b: input parameters of the function
 * @param[out] c, d: output parameters of the function
 * @return    return value: xxx
 */

 func myFunc(a int, b int)(c int, d int){
   // 代码实现
   return 0, 1
 }

where the @brief field is used to specify the overview of the function, @param[in] and @param[out] The fields are used to specify input parameters and output parameters, and the @return field is used to specify the return value of the function.

3. Variable annotation template

In Golang code, variables are the basic unit of data, so annotating variables can help other developers better understand the type and purpose of data, etc. Information, for example:

/**
 * @brief define a constant
 */
 const maxNum = 100

 /**
  * @brief define a variable
  */
  var name string

Among them, const defines constants, and var defines variables.

3. Comment specifications

1. Comments should be concise, clear and easy to understand.

2. Comments should follow the code. Comments can be on the same line immediately after the code, or they can be commented in context at a certain distance from the code.

3. Comments should be in English as much as possible, and each field label should be used in a standardized manner, such as @param, @return, etc.

4. Comments should include necessary information, such as function functions, input and output, data types, etc.

5. Comments should avoid cold jokes and language that is unfriendly to other developers to maintain a harmonious atmosphere of teamwork.

4. Benefits of comments

1. Speed ​​up the development progress of the project.

2. Improve the maintainability of the project and reduce the probability of hidden bugs.

3. It facilitates project collaboration and code reading is more convenient.

4. Facilitate the upgrade and expansion of later projects.

Summary

Through the Golang comment template introduced in this article, we can realize the importance of comments for code development. When writing code, be sure to pay attention to the writing and specification of comments, and write the specifications and technical details in the code in comments as much as possible to make the code more readable and maintainable.
