The MLP programming language

MLP is a simple ALGOL-like programming language with closures which I designed
and implemented for a Programming Language Models course back in 2011. This
project provides a graphical interpreter for it.

MLP is implemented in Common Lisp, using the Ltk graphical toolkit. It is
known to work with Ltk 0.91 (which is included in this project), and known
NOT to work with Ltk 0.96.

How to run it

You will need:

You can then run MLP with:

sbcl --script load.lisp

You can also generate a standalone executable with:

sbcl --script load.lisp --make-executable


I wrote this for a class back in 2011 and I'm actually a bit surprised that I
can still run it at all. This project is thin on documentation (the only
documentation it had was the class final report, in Portuguese). Maybe I'll
add more information to the project wiki in the future.
