Little interpreter for Scheme

#uLisp

A small Scheme Interpreter done in Python

##Objectives

Create a Scheme language from Python, by first creating an interpreter based on a Python implementation.

Working examples

We can interpret simple expresions like the one below:

  evaluator = SyntacticEvaluator()
  global_env = add_globals(Environment())
  parser = uLispParser()

  parser.parse(('(begin '
                '(car (list 3 2))'
                ')'))
  evaluator.evaluate(parsed) #returns 3

Another simple example

  evaluator.evaluate(parser.parse("(equal 5 3)"))

What's missing

• A File parser that takes a file with .scm, that will parse and interpret the results
• A console that will support functions similar to REPL
• Add more primitives and support for global, local functions
• Bootstrap part of the langauage to Scheme
