import HaskBF.Eval
import qualified Data.ByteString.Lazy as BS
import Control.Monad.State

main = do
  -- The following will evaluate the file using stdin and stdout for I/O.

  file <- BS.readFile "/path/to/file.bf"
  (EvalSuccess _) <- evalBS defaultIOMachine file
  print "ok"


  -- The following will evaluate the file using the State monad and input
  -- provided by input

  let input  = []
      output = []
      result = execState (evalStr simulatorMachine "+.>-.") (SimState input output)
  print $ simStateOutput result == [1, -1]

Executable
