Hello, I am seriously punching my way to build Swish via .cabal ... My head is totally to the wall .... punch .. punch ..... Graham Lyle has written some seriously beautiful code .... I am trying to get to adhere to contemporary Haskell namespace convention ..... I still awaiting response from Graham vis-a-vis posting on Hackage ... I strongly think that in bioinformatics and also oil/gas industry(<< I am stuck here everyday ;^)) that Swish is a strong arena of discussion! In any case .. there are some issues: 1) I strongly suspect that in Swish 0.2.1 that some of Graham's libaries are already superseded by the Haskell prelude , e.g. HUnit, Parsec(!!!), his Sort directory/library .. Don ...please 2) Graham wrote a deterministic finite automaton ..... which is giving some grieve namespace-wise ..... please see following Swish/HaskellRDF/Dfa/Dfa.lhs:1:0: Failed to load interface for `Prelude': it is a member of package base, which is hidden vigalchin here is a fragement of Dfa.lhs:

{-# OPTIONS -fglasgow-exts #-} {-# OPTIONS -fallow-undecidable-instances #-}

module Swish.HaskellRDF.Dfa.Dfa ( Re(..), matchRe, matchRe2 ) where {- ???? import Control.Monad.Identity import Control.Monad.Reader import Control.Monad.State import Data.FiniteMap import List import Data.Array -}

import IOExts The type of a regular expression.
