Go UUID implementation
========================
[![Build Status](https://travis-ci.org/twinj/uuid.png?branch=master)](https://travis-ci.org/twinj/uuid)
[![GoDoc](http://godoc.org/github.com/twinj/uuid?status.png)](http://godoc.org/github.com/twinj/uuid)
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](http://www.ietf.org/rfc/rfc4122.txt).
# 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](http://godoc.org/github.com/twinj/uuid)
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)
