A Compiler and Type Inference System for a subset of Standard ML called Small.
- MLComp is a compiler for the Small language. Small is
- a subset of Standard ML with a few additional functions
- that may be called. This compiler is written in
- Standard ML and targets the CoCo Virtual Machine. The
- code provided here is a partial implementation of the
- compiler, serving as a starting point for students
- working in the text "Fundamentals of Programming
- Languages" by Kent D. Lee and published by Springer.

The project requires Standard ML of New Jersey be installed, SWI Prolog, and the CoCo or JCoCo virtual machine. Once these three platforms are installed the project can be compiled and run with these commands.
% make % mlcomp test0.sml
The project consists of both a compiler and a type checker. The compiler is written in Standard ML and targets the CoCo virtual machine. The type checker is written in Prolog and implements the Standard ML type inference system. The call to the type checker is initially commented out in the mlcomp script. When beginning to work with the type checker uncomment the two lines that call the type checker in the mlcomp compiler script.
Additional tests are found in this directory. Some will work right away, others require the compiler be extended to support them.
