A simple universally unique ID generation library.

UUID generator for producing universally unique identifiers based on RFC 4122 (http://www.ietf.org/rfc/rfc4122.txt).

Contains make configuration changes since this thing is a bitch to compile correclty. This library generates and parses Universally Unique Identifier (UUID), based on OSSP uuid C library. So, libossp-uuid library is pre-required. OSSP uuid (http://www.ossp.org/pkg/lib/uuid/) is a ISO-C:1999 application programming interface (API) for the generation of DCE 1.1, ISO/IEC 11578:1996 and RFC 4122 compliant UUID. It supports DCE 1.1 variant UUIDs of version 1 (time and node based), version 3 (name based, MD5), version 4 (random number based) and version 5 (name based, SHA-1).

You need to assign UUIDs to your model? UuidIt makes it as simple as adding one line of code to the according models.

The Rails UUID-aware Logger (RUL) is a plugin that adds a UUID from the current thread to all messages getting logged. With a UUID-aware log statement, you can more easily track your user's activity through your application.

HasSecureUuid provides you an easily way to generate random uuids for any model in ruby on rails. **SecureRandom::uuid** is used to generate a unique uuid, so collisions are highly unlikely.

Temporally Ordered IDs. Generate universally unique identifiers (UUID) that sort lexically in time order. Torid exists to solve the problem of generating UUIDs that when ordered lexically, they are also ordered temporally. I needed a way to generate ids for events that are entering a system with the following criteria: 1. Fast ID generation 2. No central coordinating server/system 3. No local storage 4. Library code, that is multiple apps on the same machine can use the same code and they will not generate duplicate ids 5. Eventually stored in a UUID field in a database. So 128bit ids are totally fine. The IDs that Torid generates are 128bit IDs made up of 2, 64bit parts. * 64bit microsecond level UNIX timestamp * 64bit hash of the system hostname, process id and a random value.

Provides UUID generation for Mongoid models. It includes a validator for UUIDs.

FFI Wrapper for libuuid with extra helpers for common UUID tasks like getting an array of uuids for quicker distribution

Adds a :uuid column to ActiveRecord MySQL2 Adapter. Store UUIDs as 16 bytes binary column.

UUIDs that are byte-ordered lamport clocks (timestamp, worker_id). Much simpler than type-1 UUID's crappy, weirdo layout.

Helpers to use UUID with uuidtools

Class/Module Candy For gem uuid4r

Generates RFC 4122 compliant UUIDs. These UUIDs can be treated as their raw byte representation or as human-readable strings.

UUID v4 identifier generator with support for generating and parsing UUIDs, and dependency substitution

This module creates an isomorphic representation of a UUID which is guaranteed to fit into the grammar of the XML NCName construct, which also happens to exhibit (modulo case and hyphens) the same constraints as identifiers in nearly all programming languages. Provides case sensitive (Base64) and case-insensitive (Base32) variants.

pg_space_cadet is a simple hack for postgreSQL and ActiveRecord which provides a uuids table of distributable identities of space cadets -- ActiveRecord::Base instances which use the SpaceCadetWrapper. Each space cadet has a default ActiveRecord id unique in the set of all local space cadets; a space cadet's id is derived from its uuid - UUID's are by design universally distributable.

space_cadet is a simple hack, for any ActiveRecord supported database, which provides a uuids table of distributable identities of space cadets -- ActiveRecord::Base instances which use the SpaceCadetWrapper. Each space cadet has by reference a space_id unique in the set of all local space cadets; a space cadet's space_id is derived from its uuid - UUID's are by design universally distributable.

Typed UUIDs 2 bytes are reserved in the UUID for the class enum
