Best practices include: use action verbs, specify parameters explicitly, avoid negative naming, use consistency, and consider readability.

Golang function naming rules and best practices

Naming rules

• The function name must Start with a lowercase letter.
• Compound words are joined by underscores (for example, add_two_numbers).
• The function name should accurately describe its function.
• Avoid using abbreviations or jargon.
• Keep function names concise, but descriptive enough.

Best Practices

• Use action verbs: Function names should begin with a verb describing the action it performs ( For example, create_user, find_product).
• Explicitly specify parameters: You can provide additional context by including the parameter name in the function name (e.g., add_user_to_group, get_product_by_id).
• Avoid negative naming: Do not use negative words as function names (for example, is_not_valid).
• Usage Consistency: The naming convention for functions should remain consistent throughout the project.
• Consider readability: Function names should be easy to read and understand.

Practical Case

Here are some examples of well-named functions in Go:

// 根据用户名返回用户
func getUserByUsername(username string) (*User, error)

// 根据产品 ID 获取产品
func getProductByID(id int64) (*Product, error)

// 将用户添加到组
func addUserToGroup(user *User, group *Group) error

Follow these naming rules and best practices Will help improve the readability, maintainability and understandability of Go code.
