[Haskell-cafe] How to organize code

28 Jan 2008

      Hi,

How do you organize code ?

Here is a sample.
Acturally, I am thinking about using this plan.

Any suggestions ?
...
-- BasicalType.hs
type Position = (Int,Int)
data Box = Box { pos :: Position }
data Chain = Chain { pos :: [Position] }
...
-- Object.hs
import BasicalType
class Object o where
  pos :: o -> [Position]
...
-- Type.hs
import BasicalType
import Object
instance Object Box where
  pos = return . BasicalType.pos
instance Object Chain where
  pos = BasicalType.pos
...
-- Main.hs
import Type
...
