After some time using the component, I realized I often needed to quickly generate new ulids or to convert them from one format to another so I thought having those commands would be useful.

Usage

Generate a ULID - outputs N ULID(s) separated by new lines in base 32, base 58 or RFC 4122 format

Generate 1 ULID now

php bin/console ulid:generate

Generate 1 ULID with a specific timestamp

php bin/console ulid:generate --time="2021-02-02 14:00:00"

Generate 2 ULIDs and ouput the RFC4122 format

php bin/console ulid:generate --count=2 --format=rfc4122

Generate a UUID - outputs N UUID(s) separated by new lines in RFC 4122, base 58 or base 32 format

Generate 1 UUID (defaults from the underlying factory)

php bin/console uuid:generate

Generate 1 time-based UUID now

php bin/console uuid:generate --time-based=now

Generate 1 time-based UUID with a specific timestamp

php bin/console uuid:generate --time-based="2021-02-02 14:00:00"

Generate 1 time-based UUID with a specific node

php bin/console uuid:generate --time-based=now --node=fb3502dc-137e-4849-8886-ac90d07f64a7

Generate 1 name-based UUID (there must be a default namespace in the underlying factory)

php bin/console uuid:generate --name-based=foo

Generate 1 name-based UUID with a specific namespace (overrides the default namespace from the underlying factory)

php bin/console uuid:generate --name-based=foo --namespace=fb3502dc-137e-4849-8886-ac90d07f64a7

Generate 1 random-based UUID

php bin/console uuid:generate --random-based

Generate 2 UUIDs and output their base 58 format

php bin/console uuid:generate --count=2 --format=base58

Inspect a ULID - outputs base32, base58 and RFC 4122 formats of a ULID and its humand readable timestamp if it is time-based

php bin/console ulid:inspect 01EWAKBCMWQ2C94EXNN60ZBS0Q
php bin/console ulid:inspect 1BVdfLn3ERmbjYBLCdaaLW
php bin/console ulid:inspect 01771535-b29c-b898-923b-b5a981f5e417

Inspect a UUID - outputs RFC 4122, base 58 and base 32 formats of a UUID and its human readable timestamp

php bin/console uuid:inspect a7613e0a-5986-11eb-a861-2bf05af69e52
php bin/console uuid:inspect MfnmaUvvQ1h8B14vTwt6dX
php bin/console uuid:inspect 57C4Z0MPC627NTGR9BY1DFD7JJ
