Naming conventions and rules for golang functions

Go language function naming follows the camel case naming method and must not conflict with built-in functions or keywords, and it is recommended to avoid abbreviations. Specific rules include: use camelCase naming for function names; function names that return errors are suffixed with "Err"; function names must not be the same as package names; function names must not conflict with built-in function names; function names must not use reserved words or keywords.

Go language function naming conventions and rules

In the Go language, the naming of functions follows strict conventions and rules to Ensure code readability, consistency and maintainability.

Naming convention

• Function names use camel case naming, that is, words are connected with uppercase letters.
• Do not use a leading underscore (_) as it indicates that the function is not public.
• If the function returns an error, the function name will end with "Err".
• Avoid using abbreviations or jargon unless they are well known and consistent.

Naming rules

In addition to naming conventions, the Go language also has some specific naming rules:

• Function name It must not be the same as its package name.
• Function names must not conflict with built-in function names.
• Function names must not use reserved words or keywords.

Practical case

The following is an example of a function that follows the Go language naming convention:

func ParseInt(s string, base int) (int64, error) {
    // 从字符串 s 中解析整数，以基数 base 为基准。
    // 如果解析成功，则返回整数和 nil。
    // 如果解析失败，则返回 0 和错误信息。
}

This function uses camel case naming. Its name clearly describes the purpose of the function. It also follows the "Err" rule to indicate that the function may return an error.

Additional Guidelines

• Keep function names concise and meaningful.
• Avoid using generic names such as "do" or "process".
• Name a function considering its arguments and return value.
• For private functions, you can precede the function name with a leading underscore (_).
• Use tools like gofmt or golangci-lint to enforce naming conventions and rules.
