Best practices for naming golang functions

Best practices for function naming in Go: Function names should clearly describe their functionality and avoid ambiguity or abstraction. Use the verb-noun form, with the verb describing the action and the noun expressing the result. Use snake nomenclature, with words separated by underscores. The first letter of package member functions is capitalized and follows camel case. Avoid abbreviations and use compound words or delimiters for complex names. Avoid using common names such as process, handle, do.

Go function naming best practices

Function naming is a crucial step in Go programming, it can improve the quality of the code Readability and maintainability. Here are the best practices for function naming in Go:

Clearly descriptive

Function names should clearly convey their functionality. Avoid using vague or abstract names and try to use concise and precise names that represent the specific purpose of the function. For example, use CalculateOrderTotal instead of ProcessOrder.

Use the verb-noun form

Go convention combines verbs and nouns to name functions. A verb describes the action a function performs, and a noun indicates the result of that action. For example, ReadFile, SendEmail.

Use snake nomenclature

Go function names should use snake nomenclature, that is, words are separated by underscores. For example, calculate_order_total.

Follow camel case capitalization

For package member functions, the first letter should be capitalized. For example, func ReadFile(filePath string) ([]byte, error).

Avoid abbreviations

Function names should be as concise as possible, but avoid abbreviations. For longer names, you can use compound words or separators.

Avoid common names

Avoid using common function names, such as process, handle, do. These names do not provide enough semantic information, making the code difficult to understand.

Practical case

The following example shows the best practice of function naming:

// 计算订单总额
func CalculateOrderTotal(order *Order) (float64, error) {
    // ... 你的代码 ...
}

// 向指定的地址发送电子邮件
func SendEmail(to string, subject string, body string) error {
    // ... 你的代码 ...
}

// 从指定的文件路径读取文件内容
func ReadFile(filePath string) ([]byte, error) {
    // ... 你的代码 ...
}
