Re: [Haskell] refactoring, catamorphism, termination of programs
Hi Jahannes, I don't want to make a big research project out of this, rather I think of quickly putting together a prototype that proves the concept. I figure it could be distilled from some existing refactoring suite, or be manufactured from existing building blocks. Well, HaRe -- the Haskell refactorer -- offers a full API for building transformations and refactorings for the full Haskell 98 standard. http://www.cs.kent.ac.uk/projects/refactor-fp/hare.html A new release will hopefully be released very soon (even in the next few days) which will be compatible with ghc-6.6.1. The releases on our refactoring page currently only work with GHC-6.4.*. E.g. Language.Haskell.* from the ghc libs, and perhaps Typing Haskell in Haskell? http://citeseer.ist.psu.edu/424440.html HaRe also uses the GHC API and type checker, with parts of the HaRe API extended to retrieve type information from GHC on abritrary expressions and functions. Kind regards, Chris. ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
[Haskell] refactoring, catamorphism, termination of programs
Dear all, I'm looking for a tool that implements the source code transformation replace recursion by catamorphism (fold etc.). My application is that if the transformation succeeds, it implies that the program terminates. (roughly) I don't want to make a big research project out of this, rather I think of quickly putting together a prototype that proves the concept. I figure it could be distilled from some existing refactoring suite, or be manufactured from existing building blocks. E.g. Language.Haskell.* from the ghc libs, and perhaps Typing Haskell in Haskell? http://citeseer.ist.psu.edu/424440.html Any hints appreciated. Of course, if you already have some termination prover for Haskell programs, using any method whatsoever, then you're invited to take part in the FP category of the upcoming Termination Competition, see http://www.lri.fr/~marche/termination-competition/2007/ (Also, I'd welcome your comments on the proposed form and semantics of the FP category.)

Hi Maybe this link is of interest to you: http://wiki.di.uminho.pt/twiki/bin/view/Research/PURe/WebHome. A tool called DrHylo, developed in the context of this project is available, altough I don't know how suitable it could be for you: http://wiki.di.uminho.pt/twiki/bin/view/Personal/Alcino/DrHylo.
