[Haskell-cafe] question on the Prelude .. vis-a-vis
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already superseded by the Haskell prelude , e.g. HUnit, Parsec(!!!), his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:

That would be Graham _Klyne_.

Graham includes in his source distribution a full (but out-of-date) copy
of Parsec and HUnit. I would recommend to remove them, and depend on
released Hackage versions (probably both 1.0 or thereabouts).
The Sort library came from Ralf Hinze
http://www.informatik.uni-bonn.de/~ralf/software.html
It has not been cabalised or uploaded to Hackage.

Should become {-# LANGUAGE ... #-} where the "..." needs to be
determined by experimentation.

These are in package mtl.

Data.FiniteMap no longer exists - it was superseded by Data.Map.
The two APIs are similar, except that the order of arguments is
generally reversed.

Malcolm
