Greetings, I am considering writing -in Haskell of course - a small program to translate binary files to human readable text. The trouble is that I can find no easily digestible tutorial style info on how to do binary IO in Haskell. I have read about some of the libraries that people have created to do binary IO, but the documentation wasn't sufficient to get me started (perhaps because I'm a bit dense, and also relatively new to Haskell). What I would like is to see a short example showing some code that reads from a binary file. I would also like to know what the most widely used library for doing binary IO in Haskell is. I would greatly appreciate it if someone could post a small example or two illustrating how to do binary IO in Haskell using the most widely used binary IO lib (if there is such a thing). Failing that, I would appreciate a link to some Haskell code that does binary IO that I could study. Lastly, if there is a good tutorial on doing binary IO in Haskell then I would appreciate a link to that as well. Thanks in advance, Jeff Lasslett
Here's a howto: http://www.haskell.org/hawiki/BinaryIo Look for the instance Binary code. That's where you set up your binary parsers for each Haskell type. lso, these day,s you can do a fair bit of binary hacking with Data.ByteString, without the Binary class layer over the top. Hope that helps. -- Don
