Readme for wires-0.2.0

[back to package description]


This is a functional reactive programming library for interactive applications with the following features:

  • heavy focus on real-time applications like games and simulations,

  • very small core abstraction,

  • efficient in both time and space.

Until a proper tutorial has been written, please check out the examples directory. If you have questions, join #haskell-game on If you would like to report a bug or request a feature, please file an issue.

Module overview

The library is split into two roles: applications and controllers. An application developer models interactions and implements reactive systems, i.e. the application logic. A controller developer implements the glue between the application and the real world, i.e. how events and time-varying values map to actual things on the screen or in the network. The module structure reflects that distinction:

Module | Purpose --------------------------|----------------------------------------------- Control.Wire | Application language (basically core + utils). Control.Wire.Controller | Controller language. Control.Wire.Core | Core application language. Control.Wire.Internal | You should never need this module. Control.Wire.Utils | Extra application utilities.

Modules not listed here are highly experimental and should not be used.

If you are asking yourself whether you are an application or a controller developer: at this early stage of development you are probably both, which means that you will write the application as well as connect its inputs and outputs to the real world.
