What is the naming convention for golang functions?

Go function naming follows the camel case rule, using prefixes and suffixes to distinguish functions with different uses. For example, functions starting with Is are used for Boolean checks and Get functions are used to obtain data. The suffix error indicates that the function may return an error, and the Error function returns a value of type error. Constants are written in all caps with underscores separating words.

Go function naming convention

Naming style

Go function naming adopts camel case naming method (the first letter lowercase, with the first letter of the rest of the words capitalized), which helps improve code readability and consistency. For example:

func calculateTax(amount float64) float64 {
  // ...
}

Prefixes and Suffixes

• Prefix: Some functions use specific prefixes depending on their purpose, for example Is represents the Boolean check function (IsValidEmail), Get represents the getter function (GetUserDetails).
• Suffix: Sometimes a suffix is ​​used to specify the function or return type, for example All means returning all elements of the collection (GetAllUsers) , Count represents the number of elements in the returned collection (GetUserCount).

Error handling

• error: The suffix indicates that the function may return an error (ReadFile, ComputeAverage).
• Error: The function returns a value of type error (ValidateInputError, EncodeJSONError).

Constant

• ALL_CAPS: Constants are named using all uppercase letters, and words are separated by underscores (USER_ROLE_ADMIN, MAX_LENGTH).

Practical case

// 获取当前用户的详细信息
func GetUserDetails(userID int) (User, error) {
  // ...
}

// 检查电子邮件是否有效
func IsValidEmail(email string) bool {
  // ...
}

// 计算给定金额的税费
func CalculateTax(amount float64) float64 {
  // ...
}
