Finally, in case the lack of constraints on dependencies put anyone off, please note that all deps in all three projects now have minimum and maximum bounds.

Also, I should take this chance to note that there were no cache controls in the homepages linked above, so please force reloads in your browser to see latest versions. (The pages /now/ have caching prevention so this should not be necessary again.)

And, it's nice to share your thoughts, don't you think?

This trio of related packages explores strictness control in a variety of ways.

deepseq-bounded provides classes and generic functions to artificially force evaluation, to extents controlled by static or dynamic configuration.

seqaid puts that into practise, providing a GHC plugin to auto-instrument your package with a strictness harness, which is dynamically optimisable during runtime.  This is supported directly in the GHC compilation pipeline, without requiring (or performing!) any edits to your sources.

leaky is a minimal, prototypic executable that leaks space under current state-of-the-art compilation (GHC 7.8.3 -O2, at the present time).

Reddit discussion for the three together:

Easiest way to try them all, is to install seqaid and run the demo:

  cabal install seqaid
  seqaid demo

This tests seqaid on a local copy of the leaky source package.

It turned out to be routine to extend deepseq-bounded and seqaid to dynamically configurable parallelisation (paraid?).  Many other wrappers could be explored, too!  Maybe seqaid should be renamed to koolaid or something...

It's a pretty complicated system, and just first release, so there's bound to be lots of problems.  I've not set up a bug tracker, but will maintain a casual list of bugs and feature requests at

  http://www.fremissant.net/seqaid/trac

and will set up a proper tracker if there's interest.

Any isssues (or comments), I'm here, or on the reddit discussion (or email).
