# The mathlink package

Makes it easy to write *Mathematica* packages in Haskell. Just write some
functions and provide a package specification in a simple DSL that
mimics that of *Mathematica*'s `mprep` utility.

Data marshaling is accomplished via the `MLGet` and `MLPut` classes, which
specify types that that can be read from or written to the *MathLink*
connection. Instances of these classes are provided for the obvious
standard data types, including tuples, lists, `Array`s and `UArray`s.

A Haskell function that is to be exposed to *Mathematica* has the type
signature `( MLGet a, MLPut b) => a -> IO b`.

A simple example of a *Mathematica* package:

import Foreign.MathLink -- define a function addTwo :: (Int,Int) -> IO Int addTwo (x,y) = return $ x+y -- specify a package spec :: MLSpec spec = -- start a package definition [ Eval $ "BeginPackage":@[St "Test`"] -- define a usage message for the public symbol , DeclMsg "AddTwo" "usage" "AddTwo[..] adds a pair of numbers" -- open a new (private) namespace , Eval $ "Begin":@[St "`Private`"] -- declare the function , DeclFn { callPattern = "AddTwo[x_Integer,y_Integer]" , argPattern = "{x,y}" , func = addTwo } -- close the namespaces , Eval $ "End":@[] , Eval $ "EndPackage":@[] ] -- runs theMathLinkconnection main :: IO () main = runMathLink spec
