# Cronex
[](https://travis-ci.org/jbernardo95/cronex/)
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](https://github.com/javan/whenever) Ruby gem.
## Installation
Add `cronex` to your list of dependencies in `mix.exs`:
```elixir
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.
```elixir
# 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.
```elixir
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
```
