Elerea (Eventless reactivity) is a tiny continuous-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.
Stateful signals can be safely generated at any time through a specialised monad, while stateless combinators can be used in a purely applicative style. Elerea signals can be defined recursively, and external input is trivial to attach. A unique feature of the library is that cyclic dependencies are detected on the fly and resolved by inserting delays dynamically, unless the user does it explicitly.
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.
