The Gosu Language

Gosu is a pragmatic programming language for the JVM. It has been designed with Java developers in mind by providing a set of features that allow them to be more productive without sacrificing the benefits of Java's simple syntax and type-safety. Gosu is an object oriented language with a sprinkle of functional programming features.

Gosu features:

  • Open Type System
  • Advanced type inference
  • Program files (scripts containing statements, functions, and classes at the same level)
  • Structural typing (similar TypeScript's interfaces)
  • Extension methods (aka enhancements)
  • Java interoperability
  • Lambda expressions
  • Classes/Interfaces/Enums
  • Generics (reified, covariant type parameters and no wildcards)
  • Composition (with the delegate keyword)
  • Properties
  • Null Safety (supports operator ?. etc.)
  • Named Arguments and Default Parameter Values
  • A powerful for each statement with user-defined intervals types
  • Member Literals
  • Object Initializers
  • Classpath Statement and Shebang (useful when you use Gosu as a scripting language)
  • ...and more
