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)
