Re: readFile close behaviour

Maybe I'm confused but I thought the original complaint was that GHC (which plays all these tricks) was leaking objects (file descriptors) worse than Hugs (which plays very few of these tricks). -- Alastair Reid[EMAIL PROTECTED]http://www.cs.utah.edu/~reid/ ___ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
HDirect - Make install on Win32
Hi there. Trivial comments about things that can make builds smoother: Make install in CVS HDirect doesn't copy WideString.hs and WideString.hi to the target directory. It copies the *.hi files to share rather than imports/com. It copies lib*.a to lib rather than ghc/ghc-5.02.

Re: hGetContents bug?
I'll get a strange result if the file contains the character 1A-hexadecimal (or 26-decimal): all characters beyond this point won't be printed on the screen. I think this is correct behaviour for a text file under Windows/DOS... you should open the file as binary instead. --KW 8-) ___ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
Re: Help in calling Haskell from C
On Tue, Aug 14, 2001 at 11:28:57AM -0700, Sigbjorn Finne wrote: Hi, the 0.17 documentation (and examples) wasn't updated to cover the extra argument that startupHaskell() now takes, I'm afraid. Attached is a version of tst.c from examples/server/ which shows you how to now use startupHaskell() from C. Now that 5.02 is out, I was able to get this to work with hdirect 0.18. However, there was a slight glitch. The sample code contained the following: extern void* __init_MathLibProxy; and startupHaskell(argc,argv,__init_MathLibProxy); When I tried to link the code, __init_MathLibProxy came up undefined. In looking though the library produced, __init_MathLibProxy was in fact missing. However, there was a __stginit_MathLibProxy, and when I changed the code to startup using that symbol, the code worked as it should. Don't know if I was doing anything wrong, but I though I'd mention it in case anyone else was having problems. --Mark ___ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
monad comrehension query
Hello. Is list-like monad comprehension not supported? Is there a simple elegant way of expressing ghc-extended pattern matching using `do' notation instead of list comprehension? (I dont want to end up using the case statement). I still dont understand monads too well so i apologize if this is a silly question.

Re: performUnsafeIO
[Sebastian Schulz [EMAIL PROTECTED]] hi. I need to extract an IO String to String. Remembering some function like 'performUnsafeIO :: IO a - a', I searched the hugs libs, but without a match. Does a function like this still exists? Or how can I transform IO a to a? it's called unsafePerformIO, but i'm forced to ask: are you really sure it's what you want? ;) what are you trying to do? matt -- matt hellige [EMAIL PROTECTED] http://matt.immute.net ___ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
