Tinkerbell

• Small utility libraries
• Driven (mostly) by webdev and UI
• Very "haxey"
• Active development

tink_core

• Very generic building blocks
• Base dependency for tink and coconut

tink_core 2.0

• Callback
• Signal
• Lazy
• Future
• Outcome
• Promise
• ...and more

Callback<T>

• Abstraction over T->Void
• Also supports ()->Void
• And Array<Callback<T>>
• Guards against stack overflows

CallbackLink

• Generic type for "cancellation"
  • Unsubscribe
  • Abort process
  • Dispose resources
  • etc.
• Single-use (do nothing after first use)
• Composable (pairs, sequences)
• Created from function(s)

CallbackList<T>

• Generic "listener" list
• Adds Callback<T>
• Return CallbackLink
• Handles modification during call

Signal<T>

• Type-safe signals \o/
• CallbackList with extras
• (Optionally) lazy and suspendable
• Map/filter and more

Lazy<T>

• Generic type for lazy computations
• Created from factory function or a known value
• Map/flatMap
• Implicit conversion to T

Future<T>

• Generic type for dealing with asynchrony
• (Optionally) lazy and suspendable
• Map/flatMap/etc.
• inParallel/inSequence

Outcome<Data,Failure>

• Generic Success/Failure container
• Type-safe enum type
• Convenience extension methods

Promise<T>

• Essentially a Future<Outcome<T,Error>>
• All the features of Future, plus sugar
• Convenience functions for dealing with errors

Our helpers

• promise.then(onSuccess, onError)
• FutureTools/PromiseTools.combine()
• future.with*Loader()
