Haxe – cross-platform toolkit

Haxe is a powerful open-source, general-purpose, high-level, multiplatform programming language and compiler that can produce applications and source code for many different platforms using a single unified programming language.

Code written in Haxe can be source compiled to Javascript, PHP, C++, C#, Java, Flash, and NekoVM.

Haxe is a general-purpose language with object-oriented programming, exceptions, and type inference with class parameters. Generic classes, reflectivity, iterators, and functional programming are built-in functionality of the language and libraries.

Features include:

  • Standardized language.
  • ECMA style programming for client-side, server-side & desktop.
  • Fast compiling.
  • Classic Object-Oriented class + interface model (similar to Java).
  • Strict typing but with Dynamic support.
  • Tight type checking.
  • Packages and modules.
  • Generics (type parameters) with one or several constraints, but not variance.
  • Advanced Type Inference for all variables including methods arguments and return types (except member variables).
  • Anonymous Structures with structural subtyping.
  • Strictly typed function types, functions closures and partial applications.
  • Polymorphic Methods (per-method type parameters), with constraints.
  • Optional and constant default value function arguments.
  • Explicit Inline methods and constant inlined variables.
  • Local function declarations with this capturing.
  • Automatic closure creation.
  • Powerful Enums (with constructor parameters and pattern matching) – enums are different from classes and are declared with a finite number of constructors.
  • No statements : only expressions.
  • Exceptions (try/catch).
  • Metadata.
  • Partial function call with callback.
  • Getter/Setter and more with Properties.
  • Method injection with “using” mixin.
  • Conditional Compilation.
  • Iterators.
  • Syntax shortcuts using Macros. The Haxe macro system allows compile-time code-generation without modifying the Haxe syntax.
  • Standard library that works on all platforms.
  • Platform-specific API.
