Name: elerea Version: 2.6.0 Cabal-Version: >= 1.2 Synopsis: A minimalistic FRP library Category: reactivity, FRP Description: Elerea (Eventless reactivity) is a tiny discrete time FRP implementation without the notion of event-based switching and sampling, with first-class signals (time-varying values). Reactivity is provided through various higher-order constructs that also allow the user to work with arbitrary time-varying structures containing live signals. Signals have precise and simple denotational semantics. . Stateful signals can be safely generated at any time through a monadic interface, while stateless combinators can be used in a purely applicative style. Elerea signals can be defined recursively, and external input is trivial to attach. The library comes in three major variants: . * Simple: signals are plain discrete streams isomorphic to functions over natural numbers; . * Param: adds a globally accessible input signal for convenience; . * Clocked: adds the ability to freeze whole subnetworks at will. . This is a minimal library that defines only some basic primitives, and you are advised to install @elerea-examples@ as well to get an idea how to build non-trivial systems with it. The examples are separated in order to minimise the dependencies of the core library. The @dow@ package contains a full game built on top of the simple variant. . The basic idea of the implementation is described in the WFLP 2010 paper /Efficient and Compositional Higher-Order Streams/ ().
