Even though I wanted to get the first version published, I still have plenty of ideas in the pipeline. This post will serve as a running list of planned short- to mid-term updates. I'll keep updating it as progress is made or as new ideas arise.

If you have any preferences for priorities or ideas of your own, feel free to share them! Your feedback is always welcome.

Occurify

• ✅ Implementing extension methods for timeline collections (e.g. IEnumerable<ITimeline> and IEnumerable<KeyValuePair<ITimeline, TValue>>).
• ✅ Implementing extension methods for period timeline collections (e.g. IEnumerable<IPeriodTimeline> and IEnumerable<KeyValuePair<IPeriodTimeline, TValue>>).
• Implement exclusive operator (^) for ITimeline and IPeriodTimeline.
• Implement Excludes for IPeriodTimeline
• Implement TakeWithin, TakeLastWithin, SkipWithin and SkipLastWithin for IPeriodTimeline (with PeriodIncludeOptions).
• Extend TakeWithin, TakeLastWithin, SkipWithin and SkipLastWithin with PeriodIncludeOptions.
• Cache method for ITimeline and IPeriodTimeline.
  • Could be useful for complex timelines that contain a lot of filters and need to be iterated multiple times.
• Add the option to provide a maximum amount of iterations on filter methods before throwing an exception.
• Add the option for Consolidate, Merge and Invert to throw an exception if it generates an infinte period, rather than returning a period that starts at DateTime.MinValue.
• Ability to flip timelines around a certain instant
• Ability to grow/shrink periods on a period timeline.
• Performance tests
• Performance optimizations.
• ✅ Add overloads on period ToString with format providers.
• Investigate adding iCalendar files/formats.

Occurify.TimeZones

• ✅ Investigate Cronos limitation of the year 2499. -> Proposal: Remove or Make Cronos' Year 2499 Upper Limit Configurable HangfireIO/Cronos#78
  • ✅ Possibly fix this in a fork and publish a Cronos.Unlimited or something simular, depending on whether it will be fixed in Cronos.
• Investigate adding more flexibility in handling daylight savings times.
• DateTimeOffset support
• ✅ Better ToString support for periods
• Implementation of UtcInstants & UtcPeriods classes with static helper methods.

Occurify.Astro

• Implementing moon phases/state timelines.
• Allow solar angles.

Occurify.Reactive

• ✅ Implement extension methods for scheduling composite timelines.
• ✅ Implement scheduler extension methods.

Other

• Add Quartz support.
• Possibly introducing a lower abstraction for Occurify to apply the same filtering and transformations on a INumberLine<T> rather than just ITimeline. ITimeline would then implement INumberLine<T>.
  • As I want to prevent overengineering at this point, please raise an issue if you're interested in this. The more support for such a feature, the more likely I will implement it.
