Starting Hugs98
by Amy Barnes 14 Apr '03

Hi, I don't think this was the correct email address to send queries to, but I couldn't find another. I have just installed Hugs98 on my Macintosh. I assume I need to use Darwin. I don't however know how to load the Interpreter and the user guide doesn't help much. Does anyone know the answer? Thank you, Amy Barnes

Beat the Budget!

Dear Sir or Madam If you are a smoker in the UK, in the ROI, or in Scandinavia, then we have something for you. You are probably fed up with paying high prices for your cigarettes and tobacco. Take a look at what we can do for you at http://www.cbup.com/?S=16&E=a468434eafca2f16269af754acef437f We can send you, legally, by registered air mail, direct to your door, 4 cartons of cigarettes or 30 fifty gram pouches of rolling tobacco (all brands are available) from only 170 Euros - about 115 British pounds - fully inclusive of postage and packing. Why pay more? Especially with a UK budget rise of 3.20p - which does not affect our prices!!! If you would rather not hear from us any more, this link will ensure that you are not bothered again. http://www.cbup.com/bs/off.php?S=16&E=a468434eafca2f16269af754acef437f Yours faithfully. British Smokers http://www.cbup.com/?S=16&E=a468434eafca2f16269af754acef437f

RE: fromInteger :: Integer -> Int/Word

If I remember correctly (this point has come up several times in the past), the reasoning is something like this: since Int arithmetic doesn't do any overflow checking, it's inconsistent for fromInteger to do any. Q: should (0xffffffff :: Int32) == (-1 :: Int32) we take the view that it's useful if this holds. So fromInteger on *sized* integral types doesn't do any overflow checking. Now, if a, b :: Int, should (a + b) :: Int == fromInteger (toInteger a + toInteger b) :: Int (eg. take a to be maxBound :: Int, and b to be 1, and this doesn't hold in Hugs). We take the view that this should hold, i.e. it makes no difference if the addition is done with Int or Integer because the final result is modulo 2^n (where n is the number of bits in Int). If you were to do overflow checking on Int addition, then it would also make sense to do overflow checking on fromInteger, and the above property would still hold, but to do one but not the other is inconsistent. Cheers, Simon

fromInteger :: Integer -> Int/Word
by Ross Paterson 09 Apr '03

09 Apr '03

Under Hugs, fromInteger (and thus fromIntegral) throws an exception if the argument is outside the representable range of values, while GHC just truncates. And some of the libraries rely on the GHC behaviour. It seems it's not a matter of principle with Hugs, since operations on Int or Word silently overflow, as do the built-in conversions between Int and Word types.

converting packages for Hugs
by Ross Paterson 08 Apr '03

08 Apr '03

How do you do the package conversion under Windows? I'm planning to move the ffihugs calls into convert_package, because it has a list of the modules and knows where the package's cbits and include directories are, so that less additional information is required. (The only additional information needed is which files out of cbits go with which module, and what additional libraries are needed.)
