These are some simple dirty files for fast IO in Haskell. Note that this is not supposed to be used for anything too serious. It simply exists to read large amounts of data quickly for programming competition style problems.

No emphasis are put on safety what so ever.

To compile you will simply need to add the ‘io.c’ file when compiling:

ghc Main.hs io.c

• [ ] Rewrite bytestring reader, to read giant buffer (Use GHC.IO.Decide.RawIO with FD (file descriptor)) or Sysmtm.Posix.Internals use nonblocks (
• [ ] Make Bystering parser (Buffer + offset)
• [ ] Matrix or vector vector thingies
• [ ] Benchmark number conversions
• [ ] Hashable / Hashmap
• [ ] Ouput
