Naming Conventions for Const in Go

When naming constants in Golang, a clear and consistent naming convention is crucial for code readability and maintainability. While there is no formal specification, the Go community generally follows these guidelines:

Camel Case:

For constants intended to be exported outside the package, it is recommended to use camel case. The first letter of the constant name is lowercase, and the subsequent letters of each word are capitalized.

Examples:

const MaxSize = 100
const MinTemperature = -10

Upper Case:

For constants that are internal to the package and are not meant to be exported, it is acceptable to use all uppercase letters. This convention helps distinguish between exported and unexported constants.

Examples:

const PACKAGE_VERSION = "1.0.0"
const DEBUG_MODE = true

Exceptions:

There are a few exceptions to these conventions, such as os.O_RDONLY which was borrowed directly from POSIX. However, it is generally advisable to follow the recommended naming patterns for greater code clarity.

Additional Tips:

• Avoid using abbreviations for constant names as they can be confusing.
• Consider adding a suffix, such as "_DEFAULT", to indicate a default value.
• Use descriptive and self-explanatory names to make the purpose of the constant clear.
