Changelog for the reactive-banana package

version 0.8.0.4

• Just a reupload. The previous archive was broken.

version 0.8.0.3

• Export the Future type.
• Restrict containers dependency to lower bound 0.5.

version 0.8.0.2

• Fix compilation issue with hiding empty from the module Reactive.Banana.Prim.Order.

version 0.8.0.1

• New examples Counter.hs and Octave.hs.
• Bump transfomers dependency.

version 0.8.0.0

• A new module Reactive.Banana.Prim exports primitive combinators that you can use to implement your own FRP library with a different API.
• The push-driven implementation in Reactive.Banana.Prim now has the performance characteristics of an actual push-driven implementation. Some work has gone into optimizing constant factors as well. However there is still no garbage collection for dynamically created events and behaviors.
• The accumE and accumB combinators evaluate their state to WHNF to avoid a space leak. (Fixes issue #52). On the other hand, Behavior values are evaluated on demanded, i.e. only when required by the apply combinator <@> or similar.
• Recursion between events and behaviors should now work as advertised. (Fixed issue #56).
• The deprecated liftIONow function has been removed.
• The type of the changes function now indicates that the new Behavior value is only available in the context of reactimate. A variant reactimate' makes this explicit.
• The module Control.Event.Handler now exports the AddHandler type, which is now a newtype. The module Reactive.Banana.Frameworks.AddHandler has been removed.

version 0.7.1.0

• Deprecate the liftIONow function in favor of liftIO.

version 0.7.0.0

• Dynamic event switching. Combinators are now available in the module Reactive.Banana.Switch.
• Rename NetworkDescription to Moment, add class constraint Frameworks t.
• No longer compiles with the JavaScript backend of the Utrecht Haskell compiler.
• Change the changes combinator to be less useful.

version 0.6.0.0

• Can now be compiled with the JavaScript backend of the Utrecht Haskell compiler.
• The push-driven implementations needs the UseExtensions flag to work. This flag is enabled by default.
• Minor module reorganization.

version 0.5.0.0 -- announcement

This update includes numerous changes, in particular a complete overhaul of the internal implementation. Here a partial list.

• Add collect, spill and unionWith combinators to deal with simultaneous events.
• Remove general Monoid instance for Event to simplify reasoning about simultaneous events.
• Add initial and changes combinators that allow you to observe updates to Behavior. Remove the Reactive.Banana.Incremental module.
• Rename most modules,
• Change type singaturs: The main types Event, Behavior and NetworkDescription now carry an additional phantom type.

version 0.4.3.1

• Model implementation of accumE now has the intended semantics.

version 0.4.3.0

• Change semantics: IO actions from inside reactimate may now interleave as dictated by your event-based framework (issue #15).
• Fix bug: compiling a network twice no longer fails due to lingering global state (issue #16).
• Change type: remove Typeable constraint from interpret and interpretAsHandler.
• Misc: Remove the BlackBoard application from the repository.

version 0.4.2.0

• Change type: remove Typeable constraint from fromAddHandler.
• Misc: the Vault data type gets its own package.
• Misc: reactive-banana-wx now compiles properly with cabal.
• Add some more examples to the reactive-banana-wx package.

version 0.4.1.0

• Add <@> operator for more convenience when using apply.
• Add support for value recursion to the NetworkDescription monad.
• Add many examples to reactive-banana-wx.

version 0.4.0.0 -- announcement

• Add function fromPoll to obtain behaviors from mutable data.
• Change name: run is now called actuate.
• Add derived data type Discrete.
• Add function interpretAsHandler.

version 0.3.0.0 -- announcement

• change: event networks are now first-class values, you can pause or run them.
• change type: AddHandler now expects a way to unregister event handlers.
• add example RunPause.hs

version 0.2.0.0 -- announcement

• change: now implements proper semantics as pioneered by Conal Elliott
• model implementation for semantics
• push-driven implementation for efficiency
• add example SlotMachine.hs

version 0.1.0.0

• initial release
