ZML is a work-in-progress ML compiler which targets the Z-Machine (and probably also Glulx, at some point). The intent is to provide a feature set roughly comparable to Caml Light, including:

• Hindley-Milner static type system with type inference
• Mark/sweep/compact GC
• Closures
• Tail-call optimization
• Arrays, lists, tuples, records
• Variant types
• Pattern matching
• Parametric polymorphism

Think "OCaml, but without objects, modules, polymorphic variants, or labels."

This project is very incomplete and should not be considered "useful" at this point in time. But some of the harder problems have already been solved, and some toy programs can be compiled successfully.

The compiler is licensed under the GPL version 2; see LICENSE.COMPILER for details.

The runtime library is licensed under a simplified BSD license; see LICENSE.RUNTIME-LIB for details.
