LoopDance¶ ↑

No forks. No threads. Just looped scheduler based on ‘daemon_controller` and `looper`. We call it ’Dancer’.

Easy to install¶ ↑

gem 'loop_dance'

Simple to setup¶ ↑

Create file ‘lib/loop_dance.rb’:

class Dancer1 < LoopDance::Dancer

  every 3.hours do
    User.notify_all
  end

  every 60.seconds do
    Report.checks
  end

end

LoopDance automatically starts at the rails 3 server startup.

Useful management¶ ↑

From the rails application:

Dancer1.controller.start unless Dancer1.controller.running?

By the rake tasks (TODO):

rake loop_dance:start_all
rake loop_dance:stop_all
rake loop_dance:status

rake loop_dance:dancer1:start
rake loop_dance:dancer1:stop
rake loop_dance:dancer1:status

Settings¶ ↑

class Dancer1 < LoopDance::Dancer
  mute_log            # mute redundant logging, just start, stop and errors
  disable_autostart   # disable autostart at rails server startup

Contributing to loop_dance¶ ↑

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
