Required documentation tag in Go function documentation

Go function documentation is written through comments, which contain metadata related to the function. These labels are critical to understanding and using functions and help developers write high-quality, easy-to-maintain code.

Required Document Tags:

1. Description

  • Tags: //
  • Usage: Provide a high-level description of the purpose and functionality of the function.
  • Example:

    // GetName 返回给定用户 ID 的用户姓名。
    func GetName(userID int) string {
      // ...
    }

2. Parameter

  • Tag: //param
  • Usage: Provide a name and description for each function parameter.
  • Example:

    // GetName 返回给定用户 ID 的用户姓名。
    //
    // userID:要查找的用户 ID。
    func GetName(userID int) string {
      // ...
    }

3. Return value

  • Tag: // return
  • Usage: Describe the value, type and meaning returned by the function.
  • Example:

    // GetName 返回给定用户 ID 的用户姓名。
    //
    // 返回:用户姓名,如果用户不存在则返回空字符串。
    func GetName(userID int) string {
      // ...
    }

4. Error

  • Tag://error
  • Usage: If the function may return an error, describe the type and cause of the potential error.
  • Example:

    // GetName 返回给定用户 ID 的用户姓名。
    //
    // 如果用户不存在,则返回错误。
    func GetName(userID int) (string, error) {
      // ...
    }

Practical case:

Consider the following function:

// IncrementValue 增量给定整数值。
//
// value:要增量的值。
func IncrementValue(value int) int {
    return value + 1
}

Full documentation comments:

// IncrementValue 增量给定整数值。
//
// value:要增量的值。
//
// 返回:增量后的值。
func IncrementValue(value int) int {
    return value + 1
}

Wrapping Errors in Go: Adding Context to Error ChainsWrapping Errors in Go: Adding Context to Error ChainsApr 28, 2025 am 12:02 AM

In Go, errors can be wrapped and context can be added via errors.Wrap and errors.Unwrap methods. 1) Using the new feature of the errors package, you can add context information during error propagation. 2) Help locate the problem by wrapping errors through fmt.Errorf and %w. 3) Custom error types can create more semantic errors and enhance the expressive ability of error handling.

Understanding Go's error InterfaceUnderstanding Go's error InterfaceApr 27, 2025 am 12:16 AM

Go's error interface is defined as typeerrorinterface{Error()string}, allowing any type that implements the Error() method to be considered an error. The steps for use are as follows: 1. Basically check and log errors, such as iferr!=nil{log.Printf("Anerroroccurred:%v",err)return}. 2. Create a custom error type to provide more information, such as typeMyErrorstruct{MsgstringDetailstring}. 3. Use error wrappers (since Go1.13) to add context without losing the original error message,
