Kryten
Kryten Series 4000 Mechanoid is a modular task runner written in Ruby. It's meant to run simple recurring tasks in the background using threads or daemons.
Installation
Add this line to your application's Gemfile:
gem 'kryten'And then execute:
$ bundle
Or install it yourself as:
$ gem install kryten
Usage
require 'kryten'
include Kryten
# Define work to be done in a class with a run method.
# This method will be run at an interval defined by the timer method.
# Execution happens in the background based on the type of task included.
class Work
include ThreadedTask
def run
log "working..."
end
end
# The worker can run on it's own and responds to interrupt signals.
Work.new.start # loop run method in foreground
Work.new.start_worker # loop run method in a thread
# A worker can have any number of child workers
class WorkList
include ThreadedTask
end
WorkList.new('app').workers do
[Work.new('task1'), Work.new('task2')]
end
# Run the work in separate processes instead of threads
class WorkList
include BackgroundTask

end
WorkList.new('app').workers do
[Work.new('task1'), Work.new('task2')]
end
