[Hugs] #76: Add pattern guards

#76: Add pattern guards -------------------------+-------------------------------------------------- Reporter: neil | Owner: nobody Type: enhancement | Status: new Priority: minor | Milestone: Component: hugs | Version: 200609 Keywords: | -------------------------+-------------------------------------------------- Yhc, nhc and GHC all support pattern guards. It would be lovely if Hugs did as well, since they are incredibly handy. The absence of pattern guards means that Hugs cannot compile the central StackSet module in XMonad, amongst other things. http://research.microsoft.com/Users/simonpj/Haskell/guards.html -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/76> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell

Stack overflow on words (repeat 'a')
by Neil Mitchell 26 Jun '07

26 Jun '07

Hi With the expression: words (repeat 'a') Using WinHugs Sep 06 I get a stack overflow. Using Hugs Linux May 06 I get a GC fails to reclaim sufficient space error Using GHC and Yhc both of these succeed. I have a similar issue in one of my functions which is showing the same behaviour. Thanks Neil

Build system corrupts LDFLAGS options
by Fatih Aşıcı 17 Jun '07

Hi, I am trying to compile hugs98 with LDFLAGS="-Wl,-Bdirect -Wl,-hashvals -Wl,-zdynsort" While compiling OpenGL stuff, somehow it changes LDFLAGS to -Wl -Bdirect -hashvals -zdynsort and causes the build process to fail with the following messages: i686-pc-linux-gnu-gcc: unrecognized option `-hashvals' i686-pc-linux-gnu-gcc: unrecognized option `-zdynsort' cc1: error: unrecognized command line option "-Wl" runhugs: Error occurred How can I build hugs98 with these flags? Thanks, Fatih

[Hugs] #74: Data.Word64: arithmetic overflow when evaluating maxBound + 1

#74: Data.Word64: arithmetic overflow when evaluating maxBound + 1 ---------------------------------------------------+------------------------ Reporter: guest | Owner: nobody Type: defect | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: Data.Word.Word64, arithmetic overflow | ---------------------------------------------------+------------------------ The function (fromInteger x) in Num(Data.Word.Word64) causes a program error, if x is greater or equal 2^64^. This is particularly annoying when two valid Word64 variables are to be multiplied. Take for instance {{{ Data.Word> maxbound :: Word64 18446744073709551615 Data.Word> 2*(2^63) :: Word64 Program error: arithmetic overflow Data.Word> (2^64) :: Word64 Program error: arithmetic overflow }}} GHC and GHCi return values mod 2^64^, as Hugs does also for Word32 and 2^32^. -- Ticket URL: <http://hackage.haskell.org/trac/hugs/ticket/74> Hugs <http://www.haskell.org/hugs/> Hugs 98, an interpreter for Haskell
