The elerea package
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 a latching mechanism where a signal changes its behaviour as dictated by a boolean input signal.
Elerea provides an easy to use applicative interface, supports recursive signals (a definition like sine = integral 0 (integral 1 (-sine)) works without a hitch) and arbitrary external input. 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.
