okeuday/uuid

This system is an Erlang library for generating and manipulating UUIDs, currently at version 2.0.7. It supports RFC 9562 standards, including versions 1, 3, 4, 5, 6, 7, and 8, and provides utilities for extracting datetime information and handling clock sequences. The library exposes standard namespace constants and relies on the quickrand dependency for random number generation.

The library now exposes standard UUID constants and namespaces via the new \uuid.hrl\ header file. Users can access the nil UUID (\UUID\_NIL\) and the maximum UUID value (\UUID\_MAX\) as defined in RFC 4122 and RFC 9562, as well as the standard namespaces for DNS, URL, OID, and X.500 (\UUID\_NAMESPACE\_DNS\, \UUID\_NAMESPACE\_URL\, \UUID\_NAMESPACE\_OID\, \UUID\_NAMESPACE\_X500\), facilitating consistent UUID generation and comparison across applications.

include · high confidence

The uuid library has been updated to version 2.0.7, introducing support for RFC 9562 UUID versions 6, 7, and 8 alongside the existing versions 1, 3, 4, and 5. This update includes new functions for generating and inspecting these UUID types, such as get\_v6, get\_v7, and get\_v8, and modifies the version 1 node ID generation to incorporate the distributed Erlang node name. The library now depends on the quickrand and kernel applications in addition to stdlib, and the license has changed from BSD-4-Clause to MIT.

src · high confidence

The documentation in the doc/ directory has been regenerated to reflect the uuid application version 2.0.6. This update includes the new get\_v1\_datetime/1 and get\_v1\_datetime/2 functions for extracting ISO8601 datetimes from v1 UUIDs, the increment/1 function for handling clock sequence adjustments, and the updated uuid\_to\_string/2 function with additional options. The documentation also reflects the author's email change to protonmail and the inclusion of the ordered v1 variant description.

doc · high confidence

The library now follows the RFC 9562 standard, adding support for version 6 (ordered v1), version 7 (UNIX epoch), and version 8 (custom) UUIDs, while recommending version 6 over the legacy ordered v1 variant. The license has changed from BSD to MIT, and the build system has been updated to support rebar3 with explicit dependency management for the \quickrand\ library (v2.0.7). Additionally, the README has been updated to reflect these changes and provide usage instructions for initializing the \quickrand\ dependency.

(repo-wide) · high confidence

This change introduces the initial version (2.0.7) of the Erlang UUID implementation library. The package is licensed under MIT and depends on quickrand version 2.0.7 or higher.
