identifier_uuid

UUID v4 identifier generator with support for generating and parsing UUIDs, and dependency substitution.

More on UUID v4: https://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_(random)

Synopsis

require 'identifier/uuid'

uuid = Identifier::UUID::Random.get
# => "df95804e-02fc-490a-a946-e7304942b09e"

string = "My UUID v4 is: #{uuid}"

Identifier::UUID.parse(string)
# => "df95804e-02fc-490a-a946-e7304942b09e"

Identifier::UUID.uuid?('df95804e-02fc-490a-a946-e7304942b09e')
# => true

Identifier::UUID.uuid?('something')
# => false

Dependency Configuration

This library was written according to The Doctrine of Useful Objects. As such, it can be configured as either :identifer or :uuid, and has a useful inert substitute.

require 'identifier/uuid'

class MyClass
  dependency :identifier, Identifier::UUID::Random

  def self.build
    instance = new

    Identifier::UUID::Random.configure(instance)

    instance
  end
end

instance = MyClass.new

instance.identifier.get # nil
instance.identifier.set("my string")
instance.identifier.get # "my string"

operational = MyClass.build
operational.identifier.get # "df95804e-02fc-490a-a946-e7304942b09e"
