marmot

Marmot is a scheduler, use it to schedule tasks.

The most detailled documentation is the api doc.

Installation

  1. Add the dependency to your shard.yml:

    dependencies:
  marmot:
    github: erdnaxeli/marmot

  2. Run shards install

Usage

require "marmot"

# This task will repeat every 15 minutes.
repeat_task = Marmot.every(15.minutes) { puts Time.local }
# This task will run every day at 15:28:43, and will cancel the previous task.
Marmot.every(:day, hour: 15, minute: 28, second: 43) do
  puts "It is 15:28:43: #{Time.local}"
  repeat_task.cancel
end

times = 0
channel = Channel(String).new
# This task will run every 10 seconds and will cancel itself after 10 runs.
Marmot.every(10.seconds) do |task|
  times += 1
  channel.send("#{times} times")
  if times == 10
    task.cancel
    channel.close
  end
end

Marmot.on(channel) do |task|
  if value = task.as(Marmot::OnChannelTask).value
    puts value
  else
    puts "The task was canceled"
  end
end

# Start the scheduler.
Marmot.run

Debug

You can set the env var MARMOT_DEBUG to any value to make marmot outputs debug logs.

Development

Don't forget to run the test.

As they deal with timing, they could fail if your computer is busy. Do not hesitate to run then many times if that happens.
