PLambda 1.0.0

The PLambda language

An attempt to produce a workable version of JLambda for Python. To be used mainly as a part of the IOP imaude system.

We’ll start out building a recursive interpreter, then if it gets any major use, turn it into a continuation passing style interpreter.

Note that python is not java so there will be some differences, but hopefully the spirit will shine through.

Dependencies

Python 2.7 is desired, though it might work on most pythons. You will need the antlr4 runtime:

pip install antlr4-python2-runtime

Develop

Checkout the repository and do:

make develop

Install

There is a pip package, but that will move along much slower than developing from the repository.

pip install plambda
