Hi,

I have problems with the usage of the DBSpec module. The following used to work a year ago:

testDB :: DBInfo testDB = makeDBSpec "testDB" (DBOptions False) [t1]

t1 :: TInfo t1 = makeTInfo "t1" [c1,c2]

c1 :: CInfo c1 = makeCInfo "c1" (IntT,False) c2 :: CInfo c2 = makeCInfo "c2" (StringT,False)

Now the problem is type error in (DBOptions False):

Couldn't match expected type `DBOptions' against inferred type `Database.HaskellDB.DBSpec. PPHelpers.MakeIdentifiers

So my precise problem is the usage of that "MakeIdentifiers":

MakeIdentifiers moduleName :: String -> String identifier :: String -> String toType :: String -> String

Could someone please demonstrate how to use MakeIdentifiers reasonably e.g. for the above testDB? And more general: I cannot find uptodate documentation on haskelldb. Is there something around?

Thanks Immanuel
