idgen

idgen is a drop in replacement for uuidgen implemented in Odin. Additionally, it also supports UUIDv8 and TypeIDs.

Usage

# generate UUIDv4
$ idgen
c1c792d8-8656-4c32-b245-55acf9b6e376

# generate UUIDv7
$ idgen -7
019f9a54-6594-708b-b624-15436b2053ca

# generate TypeID with prefix
$ idgen -T user

$ idgen --help
Usage:
	idgen [-C|--count] [-8|--hash-v8] [-x|--hex] [-m|--md5] [-N|--name] [-n|--namespace] [-r|--random] [-s|--sha1] [-t|--time] [-6|--time-v6] [-7|--time-v7] [-T|--type-id] [-V|--version]
Flags:
	-C, --count <uint>                | generate more uuids in loop
	-8, --hash-v8 <UUID_V8_Hash>      | generate hash-based UUIDv8 using this algorithm
	-x, --hex                         | interpret name as hex string
	-m, --md5                         | generate md5 hash (UUIDv3)
	-N, --name <string>               | generate hash-based uuid from this name
	-n, --namespace <UUID_Namespace>  | generate hash-based uuid in this namespace. available namespaces: @dns @url @oid @x500
	-r, --random                      | generate random-based UUIDv4
	-s, --sha1                        | generate sha1 hash (UUIDv5)
	-t, --time                        | generate time-based UUIDv1
	-6, --time-v6                     | generate time-based UUIDv6
	-7, --time-v7                     | generate time-based UUIDv7
	-T, --type-id <string>            | generate a TypeID with this prefix
	-V, --version                     | show version number and quit
