tubes: Effectful, iteratee-inspired stream processing based on a free monad.

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.



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.

Tubes are coroutines which can suspend computation to yield an intermediate value or continue execution by requesting an upstream value.

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

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 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.
