Hacking

To hack on this library locally, complete the installation step above. We recommend installing the nix package manager to facilitate development.

After the above tools are installed, clone the source from Github.

git clone git@github.com:arrayfire/arrayfire-haskell.git
cd arrayfire-haskell

To build and run all tests in response to file changes

nix-shell --run test-runner

To perform interactive development w/ ghcid

To interactively evaluate code in the repl

To produce the haddocks and open them in a browser

Example

{-# LANGUAGE TypeApplications, ScopedTypeVariables #-}
module Main where

import qualified ArrayFire as A
import           Control.Exception (catch)

main :: IO ()
main = print newArray `catch` (\(e :: A.AFException) -> print e)
  where
    newArray = A.matrix @Double (2,2) [ [1..], [1..] ] * A.matrix @Double (2,2) [ [2..], [2..] ]
