This package is a fork of the original pipes package by Gabriel Gonzalez. See for a comparison between the two packages. . Differences with traditional iteratees: . * /Simpler semantics/: There is only one data type ('Pipe'), two basic primitives ('await' and 'yield'), and only one way to compose 'Pipe's ('>+>'). In fact, ('>+>') is just convenient syntax for the composition operator in 'Category'. Most pipes can be implemented just using the 'Monad' instance and composition. . * /Different naming conventions/: Enumeratees are called 'Pipe's, Enumerators are 'Producer's, and Iteratees are 'Consumer's. 'Producer's and 'Consumer's are just type synonyms for 'Pipe's with either the input or output end closed. . * /Pipes form a Category/: that means that composition is associative, and that there is an identity 'Pipe'. . * /"Vertical" concatenation works on every 'Pipe'/: ('>>'), concatenates 'Pipe's. Since everything is a 'Pipe', you can use it to concatenate 'Producer's, 'Consumer's, and even intermediate 'Pipe' stages. Vertical concatenation can be combined with composition to create elaborate combinators, without the need of executing pipes in \"passes\" or resuming partially executed pipes. . Check out "Control.Pipe" for a copious introduction (in the spirit of the @iterIO@ library), and "Control.Pipe.Combinators" for some basic combinators and 'Pipe' examples.
