Flix download | SourceForge.net

Flix is a statically typed programming language combining functional, imperative, and logic paradigms, with first‑class Datalog constraints and a polymorphic effect system. Designed to run on the JVM, Flix enforces purity tracking at compile time, supports algebraic data types, tail‑call elimination, and allows entire Datalog programs as values.

Features

Functional-first design with algebraic data types and pattern matching
Built-in Datalog support and logical programming within the type system
Polymorphic effect system distinguishing pure vs impure functions
Tail-call elimination over the JVM via transformation
Whole-program compilation with monomorphization and tree-shaking
No unused code or variable shadowing allowed—enforced via compiler errors
