Slate Programming Language Help For Students

Introduction to Slate

Slate is a prototype-based object-oriented programming language based on Self, CLOS,and Smalltalk-80. Slate syntax is intended to be as familiar as possible to a Smalltalker, for the clarity of messages as phrases. Unlike the Smalltalk family, methods within Slate can be assigned to a signature of objects, instead of being installed on one favored receiver. Slate has also many further expansions of the semantics which enable more concise and natural ways to express solutions to problems. Slate also has a section for code samples (complete with syntax highlighting) on the right side of the page.
