VSoft.Ulid

A Delphi Implementation of ULID for Delphi XE2 or later.

  • 128-bit compatibility with UUID
  • Lexicographically sortable!
  • Canonically encoded as a 26 character string, as opposed to the 36 character UUID
  • Uses Crockford's base32 for better efficiency and readability (5 bits per character)
  • Case insensitive
  • No special characters (URL safe)
  • Monotonic sort order (correctly detects and handles the same millisecond)

Installation

DPM

Install VSoft.Ulid in the DPM IDE plugin, or

dpm install VSoft.Ulid .\yourproject.dproj

Manually

Clone the repository and add the VSoft.Ulid.pas file to your project, or add the repo\Source folder to your project's search path.

var
  ulid : TUlid;

  s := ulid.ToString;
  
  .....
  ulid := TUlid.Parse('01J4H739Z46PZEFF5F6X5Q338Z');
  writeln(ulid.ToString);
end;
