Air

Functional collections and utilities for Julia as light as air.

Description

Air is a Julia library that aims to take advantage of Julia's builtin immutable paradigms to provide a set of functional utilities. Air is currently heavily under development and will be changing drastically in the foreseeable future. Inspiration for Air's design is derived largely from paradigms in Clojure and Scala.

Plans

Note that most of the basic plans have already been implementted, but are currently undergoing testing.

  • Completed plans
    • None
  • Plans that are implemented but requiier testing
    • Persistent data structures:
      • PArray, a persistent array type that mimics Julia's native Array
      • PDict, a persistent dictionary type that mimics Julia's native Dict
      • PSet, a persistent set type.
      • LazyDict, a persistent lazy dictionary type.
    • Multi-threading utilities, inspired by Clojure
      • Thread-safe Delay and Promise types.
      • Thread-local Var type.
      • A Volatile type that operates with the @tx macro to ensure that all updates to references within a synchronized block are performed atomically.
      • An Actor type for sending asynchronous jobs to independent threads which also respects the atomic requirements of transactional tx blocks.
      • A Source type for safely reading from inputs such as sockets or files while respecting the syncronization of transactional tx blocks.
  • Plans that are not yet implemented
    • Persistent Record Types. Tool for defining data structures that support lazy reification of members.
    • Trransient types
      • PDict should be O(1)-time convertable into the transient TDict type that can be updated without copying memory and that can be converted into a persistent equivalent very quickly.
      • PArray and TArray should have a similar relationship.
    • ChannelSourceKernel type that creates a source kernel that pops values from a channel.
    • Better query/build/update API tools?
