Hi all, hgmp 0.1.0.0 is released! [0] hgmp is a Haskell interface to GMP[1] (for GHC with the default integer-gmp implementation of Integer). Contains type definitions and marshalling functions, to be able to write FFI bindings using Haskell's Integer and Rational types. Function bindings may come in a future version. A simple example illustrating binding to GMP's next probable-prime function: {-# LANGUAGE ForeignFunctionInterface #-} import Foreign.Ptr (Ptr(..)) import Numeric.GMP.Types (MPZ) import Numeric.GMP.Utils (withInInteger, withOutInteger_) import System.IO.Unsafe (unsafePerformIO) foreign import ccall safe "__gmpz_nextprime" mpz_nextprime :: Ptr MPZ -> Ptr MPZ -> IO () nextPrime :: Integer -> Integer nextPrime n = unsafePerformIO $ withOutInteger_ $ \rop -> withInInteger n $ \op -> mpz_nextprime rop op You can cabal install (or otherwise get it) from Hackage[2], or get (or browse[3]) the freshest sources from git: git clone https://code.mathr.co.uk/hgmp.git Any and all feedback welcome! I'm sure there are some things that could be improved, and ideas for future versions will be appreciated too.
