Cofy - A Lisp compiler / interpreter running inside a web browser.

[public domain]

The purpose of this project is to allow executing dynamically generated code
inside a web browser without security risks. For that purpose a small dialect of
Lisp is used.

There are three stages of the code:

 1. textual representation of the source in a string
 2. parsed recursive lisp data structures
 3. compiled functions ready for evaluation

A result of the evaluated functions is a Lisp data structure.
A data stucture can be converted to a string, processed by a Lisp or JavaScript
function, or compiled again as a Lisp code (metaprogramming).

Evaluation environment is capability-based. The evaluated code has access only
to features which are passed by the invoking code.


Source code:

lang/core.js       - the language compiler/interpreter

tools/test.js      - JS unit testing framework
tests/test-cofy.js - Cofy language unit tests
tests/test-test.js - unit testing framework unit tests
