Who knows, please, where there are explained
hierarchical module names?
Is this a matter of Haskell-98 or of GHC ?
I looked into both of them (and also a bit into [EMAIL PROTECTED])
but could not find a basic explanation of the point, somehow missed.
Suppose that my user package called dumatel exports a module
of kind
---------------------------
module List (union)
where
import Data.List
import qualified List
union xs ys = f (Data.List.union xs (List.union ys ys))
f = ...
---------------------------
First, the module name List conflicts with such of the base package
of GHC.
So, I change this to
---------------------------
module Dumatel.List (union)
where
where
import Data.List
import qualified List
union xs ys = f (Data.List.union xs (List.union ys ys))
f = ...
---------------------------
Second, -v key in ghc --make shows that GHC decides to search for
the module Dumatel.List only in the files
./Dumatel/*.hs
and ./Dumatel/*.lhs
So, I create a directory and put the above module to the file
./Dumatel/List.hs
Does this all mean "to use hierarchical module names"?
Does the module name "Dumatel.List" agree with Haskell-98 ?
What is the currently most convenient way to resolve module name
clashes between the packages?
Is this the above arrangement with subdirectories and module names
with dots (and with "qualified-as" import) ?
Thank you in advance for explanation.
