The tubes package
This package provides the Tube monad transformer, allowing any monad computation to become a stream processing pipeline. A computation of type Tube a b m r consumes values of type a and produces values of type b.
Specialized Tubes exist which allow for stream branching, merging, and other non-linear control. These are Source, Sink, and Channel.
Also provided are Pumps, the comonadic dual to Tubes. Examples are provided of how they can be used with Tubes but we have almost certainly only scratched the surface.
Examples and more information may be found at https://github.com/gatlin/tubes.
I seem to have trouble uploading packages where the documentation can be built correctly on Hackage. If I have (once again) messed this up, you can find Haddock documentation at https://niltag.net/tubes. I apologize for any inconvenience!
This should compile on GHC 7.8, but the problem is that previous attempts at setting the versions properly rendered Hackage unable to generate documentation. Hopefully I have this fixed but any advice is welcome.
