storing to a file

Hello, I am new to haskell, and to functional programming, and wondering how to store a Double, or any non-char, to a file. Do I have to make a char array of the double and store that? Or is it preferred to use the show and read functions? Thanks in advance, johan steunenberg

Hello Feri, thanks for your advice, I guess it sweetens the situation, though I really would like to know how to store in a binary format. Have a nice day, Johan Am Don, 2002-11-14 um 11.15 schrieb Ferenc Wagner: Johan Steunenberg [EMAIL PROTECTED] writes: how to store a Double, or any

For some reason, the York ftp links never work for me, so here are the links for the Binary data papers (practically all of their webpages only point to ftp://; for papers): Heap Compression and Binary I/O in Haskell Malcolm Wallace and Colin Runciman

Re: storing to a file

There's been mention of a Binary module; there is also one in the GHC CVS repository under (I think) compiler/ghc/utils/Binary.hs. There is currently discussion on the libraries list about getting a Binary module into the standard libraries. We are currently working out some details, but it will

There's been mention of a Binary module; .. That said, there was also a post about using plain text. I tend to agree, except for certain cases. However, that is *not* to say that you should necessarily use Show/Read. | Actually, deriving binary would be a nice thing to have in general |

Binary read/write WAS [storing to a file]

I've been fiddling with binary read/write in Haskell. I put together a little example demonstrating my lack of understanding. It creates a connection requestion XAtom and spits it out over a socket. My real hangup occurs when I get a String back from the Socket and would like it nicely
