Compiler from CuMin to SaLT

This implements a translation from the functional-logic language CuMin to the lower-level language SaLT. These programming languages and the translation are described in detail in my bachelor's thesis.

I currently don't maintain this project anymore.

Example run

The CuMin input program

length :: forall a. List a -> Nat
length list = case list of
  Nil -> 0
  Cons x xs -> 1 + length<:a:> xs

is automatically translated (after optimizations) to

length :: forall a. Set (List a -> Set Nat)
length = {\list_56 :: List a -> case list_56 of
    Nil -> {0}
    Cons x_57 xs_58 -> length<:a:> >>= (\arg_59 :: (List a
                                           -> Set Nat) -> arg_59 xs_58 >>=
      (\primOpArg_60 :: Nat -> {1 + primOpArg_60}))}

A manual translation gives the same result (up to variable renaming):

length :: forall a. Set (List a -> Set Nat)
length = { \list :: List a -> case list of
  Nil -> {0}
  Cons x xs -> length<:a:> >>=
    \length' :: (List a -> Set Nat) ->
    length' xs >>= \l :: Nat -> {1 + l} }
