ksuid

This library generates random KSUID identifiers:

https://github.com/segmentio/ksuid

This library requires a backend supporting unbounded integer arithmetic.

By default, identifiers are represented as atoms and encoded using the canonical Base62 alphabet:

0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

The generation of random identifiers uses the /dev/urandom random number generator when available. This includes macOS, Linux, *BSD, and other POSIX operating systems. On Windows, a pseudo-random generator is used, randomized using the current wall time.

Identifiers can be generated as atoms, lists of characters, or lists of character codes.

See also the cuid2, ids, nanoid, snowflakeid, uuid, and ulid libraries.

Loading

To load all entities in this library, load the loader.lgt file:

| ?- logtalk_load(ksuid(loader)).

Testing

To test this library predicates, load the tester.lgt file:

| ?- logtalk_load(ksuid(tester)).

Usage

To generate a KSUID using the default configuration:

| ?- ksuid::generate(KSUID).
KSUID = '2YBXxVf8R5A1x6Yx5Y1AL7bEmel'
yes

To generate a KSUID represented as a list of characters:

| ?- ksuid(chars, '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz')::generate(KSUID).
KSUID = ['2','Y','B','X','x','V','f','8','R','5','A','1','x','6','Y','x','5','Y','1','A','L','7','b','E','m','e','l']
yes
