Haskell Ports Library provides ports in Haskell. Ports are an abstraction for modelling variables whose values evolve over time without the need to resort to mutable variable, such as IORefs. More precisely, a port represents all values that a time-dependent variable successively take as a stream, where each element of the stream corresponds to a state change. A port supports concurrent construction of the time series, or stream of values. Ports are ideally suited for purely functional GUI interfaces that completely avoid the use of mutable variables.  [edit]  Less
