IceCubeEx

Extends gem ice_cube to handle custom rules, outside of the iCalendar spec.

First require ice_cube, and then require ice_cube_ex, by adding the following line to your application's Gemfile:

gem 'ice_cube'
gem 'ice_cube_ex'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ice_cube_ex

ice_cube_ex has new rules that can be used with ice_cube's schedules:

This rule allows to specify a number of days, which indicates a cycle, and another number of days to skip inside that cycle. For example, we want an event that starts at 2015-1-1 to recur every 5 days while skipping the last 3 days, we would do something like this:

schedule = IceCube::Schedule.new(Time.new(2015, 1, 1)) do |s|
  s.rrule IceCubeEx::Rule.day_cycle(5, 3)
end

Now try calculating next occurrences:

occurrence_time = schedule.next_occurrence(Time.new(2014-12-30))
# returns 2015-1-1

occurrence_time = schedule.next_occurrence(occurrence_time)
# returns 2015-1-2

occurrence_time = schedule.next_occurrence(occurrence_time)
# returns 2015-1-3

occurrence_time = schedule.next_occurrence(occurrence_time)
# returns 2015-1-6

occurrence_time = schedule.next_occurrence(occurrence_time)
# returns 2015-1-7

occurrence_time = schedule.next_occurrence(occurrence_time)
# returns 2015-1-8

You can also use count and until to limit your rule as you would normally do with a regular ice_cube rule.
