I have a bunch (or will have a bunch) of Python code that uses the OpenCV libraries, as well as SimpleCV. I also have a bunch of Haskell code that does some other stuff, but wants to call one function that I define in the Python. This one function returns a three-tuple of doubles.
What's the best way to go about calling this function in Haskell?
For instance, a simplified case is if I have a function in Python
# foo.py
import SimpleCV
def foo():
return (1.0,2.0,3.0)
I want to be able to do this in Haskell
-- bar.hs
main = do
putStrLn $ show pyThingy.foo
I've tried using MissingPy (http://hackage.haskell.org/package/MissingPy), but whenever I try to import the local file I just get
*** Exception: <<MissingPy.Python.Types.PyException>>
Thanks!
