Matching instances of Num
by Sven Panne 16 Jun '04

16 Jun '04

Consider the following module: ------------------------------------------------ module Foo where newtype Blah = Blah Int deriving (Eq, Show) instance Num Blah where (Blah i) + (Blah j) = Blah (i + j) (Blah i) - (Blah j) = Blah (i - j) (Blah i) * (Blah j) = Blah (i * j) negate (Blah i) = Blah (negate i) abs (Blah i) = Blah (abs i) signum (Blah i) = Blah (signum i) fromInteger x = Blah (fromInteger x) bar :: Blah -> Bool bar 0 = False bar _ = True ------------------------------------------------ nhc98 (HEAD) fails with: ------------------------------------------------ panne@jeanluc:> nhc98 -c Foo.hs Fail: What? matchAltIf at 15:9 ------------------------------------------------ I'm not sure if the error is in FixSyntax.fsExp' or Case.matchAltIf itself because I don't know enough about nhc98's dictionary handling and pattern matching. Help required... :-} Cheers, S.

malcolm 2004/06/16 07:23:10 PDT Modified files: src/compiler98 FixSyntax.hs Log: Fix a pattern-matching bug. Consider the following example: ------------------------------------------------ module Foo where newtype Blah = Blah Int deriving (Eq, Show) instance Num Blah where (Blah i) + (Blah j) = Blah (i + j) ... fromInteger x = Blah (fromInteger x) bar :: Blah -> Bool bar 0 = False bar _ = True ------------------------------------------------ nhc98 previously failed with: Fail: What? matchAltIf at 15:9 because the dictionary for (Num.fromInteger {dict:Blah} 0) in the pattern-match was being flattened to (Num.Blah.fromInteger 0), which made it impossible to later choose the right instance of (Eq.==). This fix ensures that fsExp knows whether it is in an expression context or a pattern-context, and for patterns it now refuses to flatten the dictionary.

This should really be automated somehow + be tested via a test suite... :-( Revision Changes Path 1.12 +30 -0 nhc98/include/NHC/FFI.hi

panne 2004/06/14 11:02:26 PDT Modified files: src/prelude/FFI CTypes.h CTypes.hs CTypesExtra.hs Log: * s/NUMERIC_TYPE/ARITHMETIC_TYPE/ * ARITHMETIC_TYPEs now have a Real instance (should probably be tracked in some magic .hi files => Malcolm?) * Reverted most of my attempt to make CTypes* conform to the FFI spec: I can't manage to compile any Bit instances at this stage, neither Data.Bits nor NHC.SizedTypes is available. There must be some way to teach this to nhc98 by hand first => Malcolm?
