LoopDance¶ ↑

<img src=“http://travis-ci.org/dapi/loop_dance.png” />

No forks. No threads. Just looped pseudo-scheduler based on ‘daemon_controller` and `looper`.

One dancer is one daemon.

Easy to install¶ ↑

gem 'loop_dance'

Simple to setup¶ ↑

Create file ‘lib/dancers.rb’:

class Dancer1 < LoopDance::Dancer

  every 3.hours do
    User.notify_all
  end

  every 60.seconds do
    Report.checks
  end

end

Useful management¶ ↑

From the rails application:

Dancer1.start unless Dancer1.running?

By the rake tasks:

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  true       # mute redundant logging, just start, stop and errors
  autostart true       # enable autostart at rails server startup. False by default

  # Don't trap signals. True by default (trapped)
  trap_signals false

  # daemon_controller`s options
  start_timeout   60            # 15 by default
  stop_timeout    60            # 15 by default
  log_file_activity_timeout 17  # 7 by default

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.
