syzygy

A next-gen todo library.

Powerful recurring tasks.

• Repeating tasks are common in our lives and making them should be easy. syzygy has simple and expressive interfaces into making a wide variety of repeating behaviors from a task: ranging from one-time deadlines to repeating at arbitrary intervals until a given date.

Expressive dependencies.

• Tasks naturally have dependencies, and should have flexible ways of declaring them. A task isn’t only ever dependent on its parent - it can be dependent on another arbitrary task, a given date, or some external event on your computer like an e-mail. syzygy has a highly generic template for dependencies extendable by the user as well as powerful defaults to address this problem.

Unopinionated by default.

• syzygy attempts to impose as little structure as possible by default: interfaces to Recur rules, dependencies, and tasks themselves have been designed to be as barebones as possible to allow for flexible usage on the user.
• syzygy encourages the user to layer on any complexity they need themselves via the metadata attribute of each task: a string-to-string hashmap suitable for any form of serialized data.

Infinitely extensible.

• Recur rules and dependencies are easily creatable by a user, allowing for tremendous flexibility
• Any extra information needed about a Task is storeable in the metadata hashmap, allowing for limitless client-side functionality.

Simple to the core.

• syzygy has understandable interfaces and is easy to extend, allowing the best of both worlds: power by default like in systems such as org-mode without any need to wade through half-implemented parsers and obscure documentation.
