That's right - castCWcharToChar and its dual are unlikely to be correct on Windows, where wchar_t is UTF-16. However, AFAICS the whole Windows API works in terms of UTF-16, only dealing with surrogate pairs in the text output routines. So it might sometimes be more convenient and efficient, but not strictly speaking correct, to do no conversion between a UTF-16 value and Haskell's Char in the FFI on Windows. I think we want to provide an interface that lets you do this if you know what you're doing. Cheers, Simon

RE: -fno-monomorphism-restriction

I'm not sure whether you are saying (a) or (b): a) This is a compiler bug; even with -fno-monomorphism-restriction the module should compile. Are you sure? b) this is a feature request: you want a flag -fmonomorphism-restriction to restore the monomorphism restriction even if it's been turned off by an earlier flag? rsvp Simon | -----Original Message----- | From: glasgow-haskell-users-bounces(a)haskell.org [mailto:glasgow-haskell-users- | bounces(a)haskell.org] On Behalf Of Christian Maeder | Sent: 24 November 2004 13:44 | To: GHC Users Mailing List | Subject: -fno-monomorphism-restriction | | Hi, | | I've a file ATC/Sml_cats.hs that does not compile (see below) with the | flag -fno-monomorphism-restriction (ghc 6.2.2), whereas it compiles fine | without that option.

No, the fact that GHC doesn't wait for all forked threads before terminating is the intended behaviour. If you want anything else, you can implement it. Cheers, Simon

ghc -e
by Benjamin Franksen 24 Nov '04

Hello, I want to use ghc as a script interpreter, using the '-e' option. The problem is that I can't give the script any command line arguments, because 'ghc -e' intepretes everything argument as the name of a module to compile. > cat Test.hs import System main = getArgs >>= print > ghc -e Main.main Test.hs [] > ghc -e Main.main Test.hs blabla Can't find module `blabla' (use -v to see a list of the files searched for) <interactive>:1: Failed to load interface for `Main': Bad interface file: Test.hi Test.hi: openBinaryFile: does not exist (No such file or directory) <interactive>:1: Variable not in scope: `Main.main' Is there a way to tell ghc that what follows are arguments to teh program ('main') and not to ghc itself?

User-defined operators and compound expressions using Happy
by Frank-Andre Riess 24 Nov '04

24 Nov '04

Hi there folks, once again, I've got a question related to Happy (I've got version 1.13 at the moment). Maybe, it's even more a question on formal languages, but well... How can I write a grammar that can cope with user-defined operators (of different precedences/associativities) and compound expression like function calls, if-then-else- and case-statements and the like. I tried to write it down straight forwardly, but failed terribly (alas, I didn't keep it, so I can't show you - if someone of you is versed in this issue, I can try to explain the language's constructs). Thank you so much, Frank-Andre Riess

It isn't necessary to performGC explicitly. However, you might be seeing a secondary effect due to Handles being finalised at program termination too - a common problem is writing a finaliser that tries to output something on a Handle, where the Handle gets finalised first. The original finaliser will then deadlock (or in 6.2.2 it'll get a more informative exception). This is because at program termination we just run all the outstanding finalisers without regard to ordering. Ordering is too hard to establish, and would at the least require a full GC before running each finaliser. > BTW, the sensible thing to do in this case would be to throw an > exception whenever a deadlock condition is detected. (That is, if it > can be detected.) Yes, GHC does cause exceptions to be raised on deadlock. > However, what I don't understand is why touchForeignPtr is not > honored in my example program: Note that the output text lines from > the finalizers appear *before* the last action in the program (which > is a second getChar). The finalizers *are* called by the GC, and > still the order is wrong. Note that the GC only starts the finaliser thread. The program can still terminate before this thread has run to completion (this is one reason why we say that finalisers don't always run before program termination). You have a point that the documentation is plain wrong. I'll try to fix it up for 6.4, and I think at the same time I'll remove the at-exit finalisation. Cheers, Simon

I think it was my bug report which caused the gcc folks to implement that warning message :-) GCC 3.4 is being terribly helpful by taking a rather extreme interpretation of the term "undefined behaviour" in the C99 spec to mean "abort". Unfortunately it looks like I haven't patched GHC to work around it. I patched my tree on the sourceforge Sparc machine I was using, but I can't access that right now (perhaps my account expired). IIRC, it was a simple change to the type cast in the definition of the JMP_ macro in ghc/includes/TailCall.h. Maybe change StgFunPtr to StgFun? You'll know when you get it right, because the warning will go away. Cheers, Simon

RE: [Haskell] package with ghc and ghci

I'm afraid that hasn't helped. GHC appears to be looking for a package '=DSP', but there's no indication why. Could you give us enough instructions to be able to reproduce the problem here, please?
