README

Cronex

Travis Build

A cron like system, built in Elixir, that you can mount in your supervision tree.

Cronex's DSL for adding cron jobs is inspired by whenever Ruby gem.

Installation

Add cronex to your list of dependencies in mix.exs:

def deps do
  [{:cronex, "~> 0.4.0"}]
end

Then run mix deps.get to get the package.

Getting started

Cronex makes it really easy and intuitive to schedule cron like jobs.

You use the Cronex.Scheduler module to define a scheduler and add jobs to it.

Cronex will gather jobs from the scheduler you defined and will run them at the expected time.

# Somewhere in your application define your scheduler
defmodule MyApp.Scheduler do
  use Cronex.Scheduler

  every :hour do
    IO.puts "Every hour job"
  end

  every :day, at: "10:00" do
    IO.puts "Every day job at 10:00"
  end
end

# Start scheduler with start_link
MyApp.Scheduler.start_link

# Or add it to your supervision tree
defmodule MyApp.Supervisor do
  use Supervisor

  # ...

  def init(_opts) do
    children = [
      # ...
      supervisor(MyApp.Scheduler, [])
      # ...
    ]

    supervise(children, ...)
  end

  # ...
end

You can define as much schedulers as you want.

Testing

Cronex comes with Cronex.Test module which provides helpers to test your cron jobs.

defmodule MyApp.SchedulerTest do
  use ExUnit.Case
  use Cronex.Test

  test "every hour job is defined in MyApp.Scheduler" do
    assert_job_every :hour, in: MyApp.Scheduler 
  end

  test "every day job at 10:00 is defined in MyApp.Scheduler" do
    assert_job_every :day, at: "10:00", in: MyApp.Scheduler 
  end
end
