Universally Unique Lexicographically Sortable Identifier
See details: https://github.com/ulid/spec
(asdf:load-system :ulid)
(format t "~a~&" (ulid:generate-now))represents unsigned 128-bits integer.
represents 26-characters string encoded with Crockford's Base32.
holds unsigned 128-bit integer that represents unique lexicographically sortable identifier. The first 48 bits of 128 bits are a UNIX timestamp in milliseconds for lexicographically sorting. The remaining 80 bits are randomness that ensure the identifier is unique.
returns timestamp part of ulid.
returns randomness part of ulid.
are signaled when you try to decode invalid Base32 encoded string.
converts ulid into unsigned 128-bits integer.
encodes unsigned 128-bits integer to 26-characters Crockford's Base32.
encodes ulid to 26-characters Crockford's Base32.
decodes 26-character Crockford's Base32 to unsigned 128-bit integer.
converts unsigned 128-bits integer to ulid.
decodes 26-characters Crockford's Base32 string to ulid.
generates ulid from current timestamp and randomness.
First, you should clone this repository to ~/common-lisp/ulid.
Try ULID generation on your shell:
$ make build
$ ./ulid
You can copy ./ulid binary anywhere you like.
