How should constants be named in Go?

Go Naming Conventions for Constant Initialization

In Go, constants are represented by the const keyword. While the Go language does not explicitly define naming conventions for constants, it adopts the camel-case style as used in the standard library.

Depending on whether you want to export the constant or not, the first letter of the constant's name can be uppercase or lowercase, respectively.

Here are some examples from the standard library:

  • md5.BlockSize
  • os.O_RDONLY (an exception borrowed from POSIX)
  • os.PathSeparator

By following these naming conventions, you can maintain consistency in your codebase and make it easier for others to understand your intent.
