Reactive-banana is a library for Functional Reactive Programming (FRP), written in Haskell.
See the project homepage for documentation, examples and so on.
To build and install the core library from the source repository, simply type
cd reactive-banana && cabal install && cd ..
However, to try out the GUI examples, you have to install one of the of the additional packages.
Prerequisites: the wxHaskell package
cabal install wx
Note that you need to have a development version of the wxWidgets libraries installed before building wx. If you run into
ExitFailure 1exceptions, please follow the wxHaskell Quick Start instructions and try again.
To build the wx examples, type
cd reactive-banana-wx cabal configure -fbuildExamples && cabal build cd ..
The project contains several directories:
reactive-banana— the core library
