Registry Helper

Helps with Registry related tasks...

Using

To use Registry Helper in your Mix project, first add it as a dependency:

def deps do
  [{:reg_helper, "~> 0.1"}]
end

Then run mix deps.get to install all dependencies or more specifically:

• mix deps.get reg_helper
• mix deps.unlock reg_helper (if required)
• mix deps.update reg_helper (if required)
• mix deps.compile reg_helper

In your config/config.exs file, you should then name the registry:

config :reg_helper, registry: :Registry

Examples

To log the start of an Application:

  use RegHelper
  ...
  def start _type, _args do
    import Supervisor.Spec, warn: false

    # Define workers and child supervisors to be supervised
    children = [
      supervisor(Registry, [:unique, reg_name()]),
      supervisor(SomeSupervisor, [])
    ]
    opts = [strategy: :rest_for_one, name: name()]
    log_start Supervisor.start_link(children, opts)
  end

To log the start of a Supervisor:

  use RegHelper
  ...
  def start_link do
    log_start Supervisor.start_link(__MODULE__, :ok, name: name())
  end

To log the initialization of a Supervisor:

  use RegHelper
  ...
  def init(_) do
    log_init()
    children = [...]
    supervise(children, strategy: :one_for_one)
  end

To log the initialization of a GenServer:

  use RegHelper
  ...
  def init(_) do
    log_init()
    ...
  end
