The Cyan Language

TL;DR

Cyan is a prototype-based object-oriented programming language that combines features like gradual typing, inheritance, generics, and metaprogramming, aiming to provide a flexible and powerful development environment.

Contribution

This paper introduces Cyan, a new language integrating gradual typing, prototype-based inheritance, generics, and a metaobject protocol for advanced metaprogramming.

Findings

Supports both static and dynamic typing

Enables safe object initialization and exception handling

Provides a powerful compile-time metaprogramming system

Abstract

This is the manual of Cyan, a prototype-based object-oriented language. Cyan supports gradual typing (both static and dynamic typing), single inheritance, anonymous functions, generic prototypes with concepts, non-nullable types, partially safe object initialization, an object-oriented exception handling system, and a powerful Metaobject Protocol for metaprogramming at compile-time (this is described elsewhere).
