Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Protolk

Flexible Scheme objects with message passing and prototypes

Project Info

Description

Protolk provides flexible object oriented programming in Scheme, combining encapsulation and message passing a la Smalltalk and Ruby, with prototypal inheritance a la Self and JavaScript.

Protolk is not a new language or dialect. It offers a Scheme record type and collection of procedures that can be seamlessly integrated with other Scheme code. Some optional reader extensions are also available, to add some syntax sugar for convenience.

Protolk is designed with four core principles in mind:

Requirements

Protolk itself has no runtime requirements beyond the standard library provided by Chicken 4.7.0.

The automated test suite requires the test and miscmacros eggs.

Documentation
