README
Booter
Complex applications can be composed of multiple subsystems or groups or processes, independants or dependants of
each others. And starting theses subsystems is not easy as :application.start/2
or a supervisor child spec.
Booter allows modules to define a list of boot steps using Module attributes. Each step define what to call, what it requires and enables. A directed acyclic graph is then created from theses steps, and called in the correct order.
Inspired/adapted to Elixir by RabbitMQ's boot process implemented in rabbit.erl and rabbit_misc.erl. For an in-depth explaination, read Alvaro Videla's article and slides.
Usage
Read the API documentation for full usage.
Defining boot steps
Using Booter
and the boot_step/3
macro:
defmodule MyModule do
use Booter
# without name (__MODULE__ is assumed)
boot_step mfa: {mod, fun, args}, requires: :required_step, enables: :another_step
# with name
boot_step :awesome_name, mfa: {mod, fun, args}, requires: :required_step, enables: :another_step
# With name and description
boot_step :awesome_name, "Unicorn generator", mfa: {mod,fun,args}, requires: :rainbow_server, enables: :magic
end
Start boot
Just call Booter.boot!
