Re: [Haskell-cafe] Navigating 'Strategic' programming babel
Hi Ravi, You might want to browse through Comparing Libraries for Generic Programming in Haskell: http://www.cs.uu.nl/research/techreps/repo/CS-2008/2008-010.pdf SYB and Uniplate are two widely used and well-maintained systems for strategic traversals over arbitrary datatypes. There are other options, too, but it depends on exactly what you want to do.

There are other options, too, but it depends on exactly what you want to do. My interest is language processing for which stratego, strafunski, UUAG etc are specially tailor-made. Yes Ive read the 'comparing libraries' paper in which it says that strafunski and SYB approaches are so similar that strafunski is subsumed under SYB for the purposes of that paper. However it seems that the strafunski-ecosystem being integrated with aterm etc, likewise stratego, are more suited to full-scale language processing. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Navigating 'Strategic' programming babel
Strafunski is now rather out of date - it was developed before Cabal and used a custom install depending whether or not you wanted to use the DriFt preprocessor. Andy Gill has a modern re-implementation of Strafuski on Hackage called KURE. Aside from SYB, Neil Mitchell's Uniplate is popular and generally well documented.

Re: [Haskell-cafe] Navigating 'Strategic' programming babel
I won't compare and contrast all these, but I want to point out that there is a nicer version of uniplate in the lens package.
