Generate consistent UUIDs based on an array of arguments in Ruby (via SHA256 hash)

generate_uuid.rb

require 'digest'
require 'securerandom'

def generate_uuid_from_arguments(args)
  # Convert the array to a string and then hash it
  hash = Digest::SHA256.hexdigest(args.join)

  # Use the first 32 characters of the hash to form a UUID
  uuid = [
    hash[0..7],
    hash[8..11],
    hash[12..15],
    hash[16..19],
    hash[20..31]
  ].join('-')

  uuid
end

# Example usage:
args = ['argument1', 'argument2', 'argument3']
puts generate_uuid_from_arguments(args)
