How does golang function naming consider readability and recognizability?

When naming functions in Go, you should follow these guidelines: Use verbs that clearly describe the behavior of the function. Keep function names as short and unambiguous as possible. Use camel nomenclature and capitalize the first letter of the word. For similar behavior, use similar naming patterns. Avoid using abbreviations or acronyms.

Golang Function Naming: Readability and Recognizability

In Go, functions are the basic building blocks of a program. Pay attention to readability and recognizability when naming functions to make it easier to read and understand the code. Here are some guidelines:

1. Use verbs as function names

Function names should clearly describe the behavior of the function. This is best expressed using verbs, such as CalculateAverage, ValidateInput, and SendEmail.

2. Keep it as short as possible

Function names should be as short as possible, but not at the expense of clarity. For example, you can use Validate instead of the lengthy PerformInputValidation.

3. Use camel nomenclature

The words in the function name should use camel nomenclature, that is, the first letter is capitalized. For example, calculateAverage instead of calculate_average.

4. For similar behaviors, use similar names

If multiple functions perform similar behaviors, consider using similar naming patterns. For example, you can use the GetItem and PutItem functions for different data storage operations.

5. Avoid using abbreviations or acronyms

Abbreviations and acronyms reduce readability. Try to use the full name or a self-explanatory name, such as calculateStandardDeviation instead of calcSD.

Practical case:

The following is an example of a ValidateInput function that conforms to the above principles:

func ValidateInput(input string) error {
    if len(input) == 0 {
        return errors.New("input cannot be empty")
    }
    return nil
}

By following these principles , you can create readable and easily identifiable Go function names, thereby improving the maintainability and overall quality of your code.
