Communicating with other programs (Win32)

Hi all, In my free time, I'm writing a Go program in Haskell. Main platform is GHC and GHCi under Win32. It is coming along nicely: it has a GUI and the moves it comes up with are starting to make some sense. For testing (and maybe later training :) purposes I want it to be able to play against

Wanted: Hash Tables

Dear all, I would like to use hash tables in my Haskell programs (especially in places where I use `FiniteMap String a' now). I remember there was a `class Hash' in hbc (?) and I imagine this should be combined with STArray or the like. Is there already some re-usable code for doing this?

runtime effect of polymorphic Array.!

Of course (!) is polymorphic (!) :: Ix a = Array a b - a - b but on the other hand the GHC manual says Overloaded functions are not your friend: Haskell's overloading (using type classes) is elegant, neat, etc., etc., but it is death to performance if left to linger in an

Where to ask questions regarding categories and datatypes

Hi, I have a number of questions regarding categories and datatypes. I know that many of the folk in this mailing list could answer these question, but I wonder if there is a more appropriate forum. (i.e. the question are not Haskell specific). Thanks, --Peter Douglass

Possible bug/omission in Numeric library?

There is something strange about the Haskell'98 Numeric library, which I think could be considered a bug of sorts. There are functions readDec, readOct, readHex :: (Integral a) = ReadS a which read an integer from a string in base 10, 8, or 16, but there are no corresponding show functions

Re: Possible bug/omission in Numeric library?

Hi! In fact, we might want to be slightly more general. Why don't go for a general base conversion, much like Malcolms idea but without converting every digit to a Char. Say something like toBase :: (Integral a) = a - a - [a] toBase base n | n 0 = error Numeric.toBase: can't

IO library report

The report has the following example: import IO main = do hSetBuffering stdout NoBuffering putStr Enter an integer: x1 - readNum putStr Enter another integer: x2 - readNum

IO errors

Hi guys, Me again I'm afraid... A quick look at the source looks like both GHC and NHC will simply pass on errors from the OS, so for example with module Main where import IO import Directory main :: IO() main = do catch (createDirectory this/does/not/exist/foo)
