[Hugs-bugs] Winhugs startup error
by Jim Kerr 28 Jan '04

28 Jan '04

I just installed Hugs from the file hugs98-Nov2003-1.msi. The installation seemed to go just fine, and I can start the command-line version of Hugs without any problem. If I try to run winhugs, however, this error message appears in the main window: ERROR - a closing quote, '"', was expected . and an error dialog appears with this message: FATAL ERROR: Unable to load Prelude I have attached a screenshot of this info in case that's any help. I tried uninstalling and reinstalling the package, but that didn't help. Any assistance you could provide would be much appreciated. Thanks, Jim ============= Jim Kerr Software Engineer Agilent Technologies, Inc. Santa Rosa, CA

Unfortunately the Windows version of the Nov 2003 release lacks the compiled version of Text.Regex.Posix, which is used by Text.Regex and hence by Network.URI. I don't think there's any way round this with your setup (compiling with MSVC) -- you can recompile the interpreter, but not FFI libraries (I guess?). (It needs to be linked with the stuff in fptools/base/cbits/regex)

New moderation policy and
by Byron Hale 25 Jan '04

I have had two email outages this week and may have been dropped from your list. I have been receiving as many as 1000 SPAM's/day. I notice that the Hugs-users/Hugs-bugs lists do not have any identifying header. I would like to see one, so that I know where an email belongs, without having to open it immediately. If I can get all my lists to do the same, then I can trash SPAM much more easily, and without opening it. Secondarily, I have put restrictive filters on domain name recipients. Later I plan to remove my current email address. Before I do that, I want to see my lists do something like make it difficult to harvest email addresses from lists. That could be by mangling the return address so that human intervention was needed. Any list that does not adopt these measures will ultimately be dropped. I just can't take so much SPAM, 4 or 5 times the volume of email that can efficiently be handled.. Best Regards, Byron Hale

[Hugs-bugs] problem with winhugs
by K, W, Armstrong 25 Jan '04

25 Jan '04

I am using Windows ME. When I attempt to start WinHugs the window opens and gives an error message of " ERROR - a closing quote, ' " ' , was expected". Also a windows dialog box appears and says "Fatal error: unable to load prelude". Hugs itself works fine. I have tried reinstalling (and with new downloads) but it makes no diference. Ken Armstrong

Oops - looks like we didn't have list name tags on any of the Haskell lists. I've fixed haskell, haskell-cafe, hugs-bugs, and hugs-users. You'll see [Hugs-bugs] at the start of all subjects to this list now. John

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

Winhugs crashes

Hi, I just programmed something for a class, when I discovered the following bug. I am running "winhugs +s +t +f -g -G -l +e -. -q -Q +w -k -o -O +u -I +i +R -H -T -W +X -N" under Windows XP. My piece of code: -- code start data Monat = Januar | Februar | März | April | Mai | Juni | Juli | August | September | Oktober | November | Dezember deriving Show instance Enum Monat where toEnum 1 = Januar toEnum 2 = Februar toEnum 3 = März toEnum 4 = April toEnum 5 = Mai toEnum 6 = Juni toEnum 7 = Juli toEnum 8 = August toEnum 9 = September toEnum 10 = Oktober toEnum 11 = November toEnum 12 = Dezember fromEnum Januar = 1 fromEnum Februar = 2 fromEnum März = 3 fromEnum April = 4 fromEnum Mai = 5 fromEnum Juni = 6 fromEnum Juli = 7 fromEnum August = 8 fromEnum September = 9 fromEnum Oktober = 10 fromEnum November = 11 fromEnum Dezember = 12 succ m = toEnum (rem (1 + (fromEnum m)) 12) pred m | (fromEnum m) == 1 = Dezember | otherwise = (toEnum . subtract 1 . fromEnum) m data Datum = Datum Int Monat Int deriving Show instance Eq Datum instance Ord Datum -- code end Now if I ask in Winhugs what (Datum 12 Januar 2004) == (Datum 12 Januar 2004) is, it crashes: Process winhugs exited with code 128.
