The pipes package
"Iteratees done right". This library implements iteratees/enumerators/enumeratees simply and elegantly, using different naming conventions.
Advantages over traditional iteratee implementations:
Simpler semantics: There is only one data type (
Pipe), two primitives (
yield), and only one way to compose
.). In fact, this library implements its entire behavior using its
Categoryinstances and enforces their laws strictly!
Clearer naming conventions: Enumeratees are called
Pipes, Enumerators are
Producers, and Iteratees are
Consumers are just type synonyms for
Pipes with either the input or output end closed.
Pipes are Categories: You compose them using ordinary composition.
Intuitive: Pipe composition is easier to reason about because it is a true
Category. Composition works seamlessly and you don't have to worry about restarting iteratees, feeding new input, etc. "It just works".
Vertical concatenation works flawlessly on everything: (
Pipes, but since everything is a
Pipe, you can use it to concatenate
Consumers, and even intermediate
Pipestages. Vertical Concatenation always works the way you expect, picking up where the previous
Bidirectionality: The library now provides a bidirectional
Pipetype, called a

Control.Pipe for the actual implementation. Control.Proxy.Tutorial
introduces bidirectional iteratees that are backwards-compatible with
and Control.Proxy provides the implementation.
