How does golang function naming adapt to continuous development and refactoring?

Careful choice of function names is crucial for persistent code in Go. Function names should clearly communicate the purpose of the function (such as Calculate Sales Tax), stay concise (such as OrderTotalByCustomer), and follow a consistent naming style (such as snake case or camel case). By following these principles, you can improve the readability, maintainability, and debuggability of your code.

Golang Function Naming: Adapting to Continuous Development and Refactoring

Key factors for writing durable and maintainable code in Go One is to choose function names carefully. Function names should accurately reflect the functionality and intent of the function while maintaining simplicity. Doing so helps improve the readability, maintainability, and debuggability of your code.

Readability and Clarity

Function names should clearly convey the purpose of the function and use domain-specific terminology. Avoid using vague or general names, such as process() or handle(), which may make it difficult to understand their specific functionality.

Examples of correct function names:

func Calculate營業稅(amount float64, percentage float64) float64
func GetCustomerByName(name string) (*Customer, error)

Succinctness

While names should be descriptive, they should also be kept concise and avoid unnecessary of verbosity. Use abbreviations, compound words, and other concise techniques while ensuring that the meaning of the function name is not compromised.

Example of overly verbose function name:

func FunctionToCalculateTheTotalAmountOfOrdersPlacedByCustomer(customerID int) float64

Improved concise example:

func OrderTotalByCustomer(customerID int) float64

Consistency

Perform function naming Style is very important. This helps maintain consistency and style throughout the code base. It is recommended to use snake case or camel case naming conventions and be sure to use them consistently throughout your code.

Practical Cases

The following are some examples of how to apply these principles to function naming in actual scenarios:

E-commerce system

• Calculate Sales Tax(): Calculate the sales tax for a given amount.
• GetOrderTotal(): Get the total amount of a specific order.
• AddProductToCart(): Add a product to a specific location in the shopping cart.

User Management System

• CreateUser(): Create a new user.
• GetUserByEmail(): Get a specific user by email.
• UpdateUserPassword(): Update user password.

By adopting these principles, you can create descriptive, understandable, and consistent function names, thereby improving the quality and maintainability of your Golang code.
