New moderation policy
by John Peterson 15 Jan '04

15 Jan '04

I'm about to take off for the holidays and I'm going to change the spam policy for the hugs mailing lists. Previously, non-listmember mail was held for approval. As part of the approval process I would whitelist email addresses so that you only had messages held the first time you post. This only affects people with multiple email addresses who are posting from an address different from thier subscription address. Since I'll be gone for a couple of weeks, I've set the list to reject instead of approve non-member email. This means that you're going to be on your own to modify your subscription address if there are problems with posting. I'll still take private email requests to whitelist addresses but I won't be attending to email much for the next few weeks. Over the last few months I've observed fewer and fewer problems with legitimate posts being held and more and more spam being held for approval so I'm hoping that this new policy will make my life easier without being a burden to too many posters. Keeping your email spam free, John

INTERNAL ERROR: findBtyvsInt strikes again!
by Alexandru D. Salcianu 19 Dec '03

19 Dec '03

Hello! I'm using Hugs (the November 2002 version) and I've encountered the "INTERNAL ERROR: findBtyvsInt" error. I've read online that this error was known in the November 1999 version, but was fixed in the 2000 version. I'm using the 2002 version and still get it. I've encountered the error while working on a collection library (of course, I'm using the multi-parameter typeclass extension). $ hugs -98 __ __ __ __ ____ ___ _________________________________________ || || || || || || ||__ Hugs 98: Based on the Haskell 98 standard ||___|| ||__|| ||__|| __|| Copyright (c) 1994-2002 ||---|| ___|| World Wide Web: http://haskell.org/hugs || || Report bugs to: hugs-bugs(a)haskell.org || || Version: November 2002 _________________________________________ Hugs mode: Restart with command line option +98 for Haskell 98 mode Reading file "/usr/lib/hugs/lib/Prelude.hs": Hugs session for: /usr/lib/hugs/lib/Prelude.hs Type :? for help Prelude> :load Map.hs Reading file "Map.hs": Type checking INTERNAL ERROR: findBtyvsInt Prelude> :version -- Hugs Version November 2002 Here is the content of Map.hs: module Map where -- objects of type ce represent sets of e's class (Eq e) => Set e ce | ce -> e where equalSet :: ce -> ce -> Bool -- objects of type map represent maps from key to value class (Eq key) => FiniteMap key value map | map -> key value where -- returns all keys from map, as a set of type keyset mapKeys :: (Set key keyset) => map -> keyset equalMap :: map -> map -> Bool {-- ERROR in this incomplete default implem. of equalMap --} equalMap m1 m2 = let (keys1 :: [key]) = (mapKeys m1) (keys2 :: [key]) = (mapKeys m2) in equalSet keys1 keys2 instance (Eq a) => Set a [a] where equalSet = (==) (I've trimmed the code down to obtain a small bug report; the above code should be enough to trigger the error).

WinHugs
by Peter Bachmann 17 Dec '03

17 Dec '03

Dear friends, I have used Haskell for education since several years very succesfully. Just today; I downloaded the hugs98-Nov/2003-1.msi version. The first time I startet WinHugs it worked. Then I changed the option using Textpad as Editor. After that I got always the message Window: "FATAL ERROR: Unable to load Prelude" and in the client area of hugs the message ERROR - a closing quote , '"', was expected. I deinstalled hugs completely and repeated installation procedure but, the same effect I got again. What can I do? Thank you for the hints, Peter ------------------------------------------------------ Prof. Dr. Peter Bachmann Cottbus University of Technology P.O.

FLOAT PRECISSION
by mike V 15 Dec '03

15 Dec '03

What is the precission with which floating point operations are performed ? The following example shows an incorrect answer in the second case ? How can this problem be addressed i.e. the apparent precission seems to be a sevre limitation to any scientific computation ?

Haskell
by "Борис Каменов" 15 Dec '03

15 Dec '03

Hallo freaks, I just wanna say that your stupid language called Haskell is getting on my nerves. In our stupid university our stupid professors have decided that we MUST learn this stupid language. Can you tell me pleaZZZZZe what is the purpose of using this shit instead of writing smart and normal programs in C++ or ASM or in whatever smarter than this BIG shit. I was unable to find some normal documentation about your Virus-kind script neither an INTERPRETER that gives me some easyness when I write my heart-breaking homeworks. I was also unable to find JUST ONE program that uses this script (I would not call this a language). Tell me why, tell me why you had made this. You had to waste your time with something different. There are, for example, women. They are smarter then this shit and can make more things such as "openWindow", "cloaseWindow" and so on and so fort. OK, I must go. My homework awaits me but before I say good bye I wanna say "I`m not one of the lamers which have no idea what the word programming means. That is why I criticize you on developing such things."

Registry problems
by Sven Panne 07 Dec '03

07 Dec '03

Perhaps we (= Sigbjorn :-) should make a patchlevel release of the new Hugs, otherwise I fear that we continue getting daily complaints about the malformed registry entry... Apart from that nothing really bad has been reported, so this could be the only change. Any opinions on this? Cheers, S.

Corrupted registry when changing Options in Nov 2003 release
by Bernd Holzmüller 05 Dec '03

05 Dec '03

I use winhugs of Hugs98 November 2003 version. I observer the following problems: 1) When I change the options of winhugs using the menu, the registry seems to become corrupted, so that further calls to winhugs abort with the message: ERROR, a closing quote was expected. 2) Dropping a file into winhugs leads to strange error messages like: ERROR "C:\Programme\Hugs98\libraries\Hugs\Char.hs":19 - Undefined type constructor "Char".

INTERNAL ERROR: Error in graph
by Henk-Jan.van.Tuyl 04 Dec '03

04 Dec '03

Sorry, forgot to attach the source code. L.S., Hugs gives the following error message when running the attached program: Program error: Program error: pattern match failure (288112 reductions, 525181 cells, 9 garbage collections) INTERNAL ERROR: Error in graph This happens after reading 508 files; heap space is 250000. The problem most probably stems from the return of function collectFileData, as this was the last changed part. I am runnnig Hugs Nov 2003 on Windos 98. -- Best regards, Henk-Jan van Tuyl
