ScheduledValue

ScheduledValue provides a set of Ruby classes for representing values that change over time based on a schedule. One way to think about this is that for a regular variable, you could reasonably ask "what is its value?" For a ScheduledValue, you have to ask "what is its value right now?" Some examples of this might be:

• an on-call rotation (who is on call right now?)
• pricing for an event with early bird tickets (what is the price right now?)

ScheduledValue also provides a ScheduledValue::Timespan class that represents a span of time, which may have a defined start point, a defined end point, both, or neither. ScheduledValue::Timespans are Ruby Comparable objects.

All classes in the ScheduledValue gem are designed to be serializable to and from dictionary-like formats, such as JSON and YAML. This makes it easy to use them with ActiveRecord's serialize class method and other similar techniques for storing them in a database column.

Installation

Add this line to your application's Gemfile:

gem 'scheduled_value'

And then execute:

$ bundle

Or install it yourself as:

$ gem install scheduled_value

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
