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
