Go UUID implementation

Build Status GoDoc

This package provides RFC 4122 compliant UUIDs. It will generate the following:

  • Version 1: based on timestamp and MAC address
  • Version 3: based on MD5 hash
  • Version 4: based on cryptographically secure random numbers
  • Version 5: based on SHA-1 hash

Functions NewV1, NewV3, NewV4, NewV5, New, NewHex and Parse() for generating versions 3, 4 and 5 UUIDs are as specified in RFC 4122.

Requirements

Go 1.4, 1.3, 1.2 and tip supported.

Recent Changes

  • Removed use of OS Thread locking and runtime package requirement
  • Changed String() output to CleanHyphen to match the canonical standard
  • Plenty of minor change and housekeeping
  • Removed default saver and replaced with interface
  • API changes to simplify use.
  • Added formatting support for user defined formats
  • Added support for Google App Engine
  • Variant type bits are now set correctly
  • Variant type can now be retrieved more efficiently
  • New tests for variant setting to confirm correctness
  • New tests added to confirm proper version setting
  • Type UUID change to UUIDArray for V3-5 UUIDs and UUIDStruct added for V1 UUIDs ** These implement the BinaryMarshaller and BinaryUnmarshaller interfaces
  • New was added to create a base UUID from a []byte slice - this uses UUIDArray
  • ParseHex was renamed to ParseUUID
  • NewHex now performs unsafe creation of UUID from a hex string
  • NewV3 and NewV5 now take anything that implements the Stringer interface
  • V1 UUIDs can now be created
  • The printing format can be changed

Installation

Use the go tool:

$ go get github.com/twinj/uuid

Usage

See documentation and examples for more information.

var config = uuid.StateSaverConfig{SaveReport: true, SaveSchedule: 30 * time.Minute}
uuid.SetupFileSystemStateSaver(config)

u1 := uuid.NewV1()
uP, _ := uuid.Parse("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
u3 := uuid.NewV3(uP, uuid.Name("test"))
u4 := uuid.NewV4()
fmt.Printf(print, u4.Version(), u4.Variant(), u4)

u5 := uuid.NewV5(uuid.NamespaceURL, uuid.Name("test"))

if uuid.Equal(u1, u3) {
	fmt.Printf("Will never happen")
}
fmt.Printf(uuid.Formatter(u5, uuid.CurlyHyphen))

uuid.SwitchFormat(uuid.BracketHyphen)
