(Updated to Netwire 3.0.0 – incomplete)
Revision as of 15:17, 1 December 2011
Netwire is a library for functional reactive programming, which uses the concept of arrows for modelling an embedded domain-specific language. This language lets you express reactive systems, which means systems that change over time. It shares the basic concept with Yampa and its fork Animas, but it is itself not a fork and has many additional features.
This wiki page corresponds to Netwire version 3 and is currently a work in progress.
Here is a list of some of the features of Netwire:
- arrow interface (or optionally an applicative interface),
- signal inhibition (ArrowZero / Alternative),
- signal selection (ArrowPlus / Alternative),
- self-adjusting wires (ArrowChoice),
- rich set of event wires,
- signal analysis wires (average, peak, etc.),
- effectful wires.
2 BasicsThe Netwire library is based around a data type called
data Wire e (>~) a b
comp :: Wire e (>~) a b
a >~ Either e b
