state.swift

Finite state machine for Swift.

If you like the way this is progressing, please star it...

This is very much a work in progress; please check back for progress. If you'd like to see what's coming, take a look at the state.js and state.cs projects.

Swift is a very new language to me so any suggestions via Github issues are very welcome.

Progress

  • 2016-04-18: Split runtime code from model code.
  • 2016-04-15: Add element removal code.
  • 2016-04-13: Finish commenting.
  • 2016-04-12: Tidying and comments.
  • 2016-04-08: Added exception handling and starting to tidy and comment code.
  • 2016-04-01: Last of the file refactoring
  • 2016-03-25: Remove ++ and -- operators as they're now deprecated and will be dropped in Swift 3.
  • 2016-03-18: Initial re-factoring into a file per class.
  • 2016-03-18: Well, it's been a long journey, but here is some working code; still a way from RC1 but proves it can be done in Swift.
  • 2016-01-29: Simplify example code; added another visitor.
  • 2016-01-28: Add templated state machine instance into the model; migrate some functions to computed properties.
  • 2016-01-13: Complete the model building code.
  • 2016-01-09: Declare immutable properties of classes with let; extract Element from NamedElement and derive Transition from Element; add transitions to their parent vertex.
  • 2016-01-08: Make NamedElement implement Hashable to be able to use model elements in Sets and as the key to Dictionaries.
  • 2016-01-07: Add guards to transitions.
  • 2016-01-06: Add entry/exit callbacks for states.
  • 2016-01-05: Add convenience init methods to allow direct use of states as vertex parents.
  • 2016-01-04: Add a lazy defaultRegion mehtod to state and stronger example model.
  • 2015-12-11: Add a Guard and Behavior types.
  • 2015-12-09: Building the model structure is underway.
