However, I'm not sure it's worth making this generalisation, since it would necessarily complicate the library quite a bit. Do you have an application where being in the IO monad to do this stuff isn't possible, or is inconvenient? Cheers, Simon

The home page of the York Binary library seems to be http://www.cs.york.ac.uk/fp/nhc13/libs/Binary.html Malcolm will doubtless have something to say here. However I would say not that there's something "wrong" with the Binary/BinArray library, but that it seems to be addressed towards a different class of problems (specifically data-compression) to those I am interested in (blasting data rapidly in and out). The main differences are (1) the framework I proposed in the original message: http://haskell.org/pipermail/glasgow-haskell-users/2003-May/005166.html is byte-based, while the York Binary framework is bit-based. I would imagine that this means the York Binary framework would be very much less efficient at handling long sequences of bytes, since they will presumably have to be shifted before being written to the destination. (2) the York Binary library uses the IO monad, and presumably various variables within a BinHandle, to keep track of state. I think this is unnecessary, for example I don't think the process of converting a value to a byte array should really have to go through IO. We are supposed to be functional programmers after all. (3) the York binary library provides two things you can write bits to (a Handle, and a fixed area in memory) and a large set of operations (seek and co), but it would be difficult for a normal programmer to extend this. (For example, what about someone in GHC wanting to write to a Posix Fd?) On the other hand the framework I propose has only two basic operations for writing, and two for reading, which means it should be much easier to define alternative consumers and sources of binary data.

Whether you > use functional arrays or lists is somewhat irrelevant -- functional arrays > are also exceedingly slow. I completely agree that going via lists of Word8's is unacceptable. My design does not require this. An array of Word8's can be written or read to a file in a single operation (not counting the length, which needs to be communicated some other way). When you need to write to an intermediate data structure, the most efficient implementation would probably be to write directly to an array, which you realloc as necessary. This could be wrapped up into a single pure operation of type :: HasBinaryWrite a => a -> Bytes (say). Of course you would need to use IO in the middle, since it happens that the current interfaces to blocks of reallocable bytes require IO, but I don't really see how that can be avoided, and the end-user doesn't have to see it.

hsc2hs feature request
by Nicolas Oury 20 May '03

20 May '03

Hello, I don't know if it's the place for that but I've got a problem with hsc2hs. In the C output file, it produces a main function of type int main (void) I think, it would be better to produce int main (int argc, char *argv []) It could seem not important, but with some C libs (for example SDL on OS X) that overwrite the main function with their main function and redirect main to SDL_main, it creates problems. (I've got a conflicting type with declaration which disappears if I correct this). Best regards, Nicolas Oury

Converting things to and from binary
by George Russell 20 May '03

20 May '03

Sorry, I know there was an ongoing discussion on this topic somewhere, but I can't find it, so I'll have to hope this list is the most appropriate. The general problem to solve is "How to we convert things to and from a binary format, so they can be efficiently written to and from disk". I have solved this (incompletely) twice myself, I expect Glasgow Haskell has solved it too, there really ought to be a standard solution. From the deficiencies of my incomplete solutions I conclude: (1) you don't want to force everything to go via single Haskell characters. This is horrendously inefficient when what you want is to blast in and out large quantities of binary data, and of course that's precisely where you probably want efficiency. (2) you don't want a binary converter only to be able to write to Handles. I've found myself that it's useful to be able to convert to (for example) vectors of bytes. Now my idea is that this be implemented using monads. For example, consider the problem of writing out data to be converted into binary. We might consider there to be two primitive operations, based on the types Byte (a single Byte) and Bytes (an array of bytes). (I'm not sure exactly what these types should actually be in GHC.) The consumer of binary data should provide a record like data WriteBinaryData m = WriteBinaryData { writeByte :: Byte -> m (), writeBytes :: Bytes -> m () } Then something which can be written out in a binary form would instance the class class HasBinaryWrite a where writeA :: Monad m => WriteBinaryData m -> a -> m () The advantage of this approach is that an instance of HasBinary can both be written to a file (m = IO) and to a byte vector. Also this should be fairly efficient I think, and it should be easy to build up more complex instances of binary. The converse functions would likewise use monads data ReadBinaryData m = ReadBinaryData { readByte :: m Byte, readBytes :: Int -> m Bytes } class HasBinaryRead a where readA :: Monad m => ReadBinaryData m -> m a and again we can instance this either for files or for byte vectors, and again building up more complex instances should be easy enough. I wonder if this is the best way of doing this kind of thing, and if so should it be implemented and put in the standard libraries? Also, what should Byte and Bytes actually be?

please help me
by John Jonas Savimbi 19 May '03

From: John Jonas Savimbi Johannesburg, South Africa Email: jjsavimbi(a)phantomemail.com May 19TH, 2003. Dear Sir, It is my humble pleasure to write you this letter irrespective of the fact that you do not know me. However, I got your name through your country business directory here in my search for a reliable and trustworthy person that can assist me confidently. My name is Mr.John Jonas Savimbi. I am the son of Late Dr. Jonas Savimbi from Angola. I am 29 years old and I have got two younger sisters of same blood. Our mother died almost a year ago. We are all fighting for political asylum in South Africa. We cannot find a home in Angola anymore because of the war that our late father fought with the government of Angola until he died in that war. The government of Angola is now mad at us because our late father also wanted to be president and caused the people to fight the war for him because he was the president of UNITA political movement of Angola. So now we are in South Africa and we are suffering too much because we don't have money and the government of South Africa will not give jobs to asylum seekers. I am much concerned about my younger sisters who are finding it very difficult to manage in the situation. But I know that we should not suffer this way. I know that I must not let my younger sisters get into trouble because of money. So after consideration I am hereby begging for your assistance to help me to recover the sum of USD $29 Million which is my inheritance from my late mother. My late mother had taken this money with her to Spain in a diplomatic metal box marked (Precious Stones). Subsequently she lodged the metal box (As precious Stones) with a Securities and Valuables Protection company in Spain. I am supposed to be the beneficiary in the event of her death. However, all effort I made to go Spain to claim was refused by the Spainish embassy. And this was while it was still possible for me to travel. Now I cannot travel anywhere anymore. So in the situation that we are facing now, I must find somebody who can go to the Spain on my behalf. I understand that I will have to transfer my beneficiary rights unto you. I am willing to do so in the hope that you are a God fearing person who will not abandon us after you have the money. So from the bottom of my heart I am giving you 20% of the all the money. Once we have enough to sustain us sufficiently, you may be come our fund manager and invest the rest wisely for us. If you will be kind to assist us, please inform me urgently. Kind regards to you and your family. Sincerely, John Jonas savimbi

How can I compile C/Haskell program with my own WinMain function? I try ghc -fglasgow-exts -c Foo.hs gcc -Ie:\ghc\include -c win_ghc.c ghc -o win_ghc.exe -no-hs-main Foo_stub.o win_ghc.o Foo.o and got an error > ghc -o win_ghc.exe -no-hs-main -lgdi32 Foo_stub.o win_ghc.o Foo.o e:/ghc/libHSrts.a(Main.o)(.text+0x82):Main.c: undefined reference to `__stginit_Main' e:/ghc/libHSrts.a(Main.o)(.text+0x93):Main.c: undefined reference to `Main_zdmain_closure' Similar works properly: ghc -fglasgow-exts -c Foo.hs gcc -Ie:\ghc\include -c ffi.c ghc -o ffi.exe -no-hs-main Foo_stub.o ffi.o Foo.o ffi.c contains main(), but win_ghc.c contains WinMain() instead of main(). Best regards, Roman Beslik.
