Go language function naming: best practices for using verbs

In the Go language, the function naming convention is to use Action verb, a word that describes the behavior or goal of a function. Use verbs to make function names clear, concise, and easy to understand.

When to use verbs?

• When creating, updating or deleting resources (such as CreateUser(), UpdateUser(), DeleteUser() )
• When operating or converting data (such as SortData(), FilterData(), ConvertToString())
• When controlling a process or making a decision (such as HandleRequest(), Decide(), CheckPermissions())
• when returning information or values ​​( For example GetUserDetails(), CalculateTotal(), PrintMessage())

Actual case:

// 计算订单总额
func CalculateOrderTotal(order *Order) float64 {
    // ... 计算订单总额的代码 ...
    return total
}

// 处理 HTTP 请求
func HandleRequest(w http.ResponseWriter, r *http.Request) {
    // ... 处理 HTTP 请求的代码 ...
}

// 将字符串转换为整型
func ConvertStringToInt(s string) int {
    // ... 将字符串转换为整型的代码 ...
    return i
}

Tip:

• Use verbs in the past tense or progressive tense to express actions completed immediately after the function is executed (for example, CreatedUser(), CreatingUser()).
• Use verbs in the present tense to express ongoing or ongoing actions in function execution (such as HandleRequest(), CalculatingOrderTotal()).
• Avoid using descriptive words (such as GoodUser(), BadFunction()) as these words may change meaning over time.
• Make sure the function name is specific enough to reflect its exact behavior.
• Keep function names short and consistent to improve readability and maintainability.
