Lux is a functional, statically-typed Lisp programming language with a compiler that targets the JVM, JavaScript, Python, Lua, and Ruby. It features monadic macros, extensible compiler semantics, first-class types as data structures, and multiple concurrency paradigms including STM, FRP, and the actor model.

Use cases

• write statically-typed functional programs in a lisp syntax
• compile one codebase to jvm bytecode and javascript
• build polyglot libraries consumable from java python ruby or lua
• experiment with extensible language semantics and compiler extensions
• use macros to generate type-driven code
• explore concurrency paradigms like stm frp and actors

When to choose

• you want a lisp with static types and functional programming
• you need a single language compiling to multiple platforms like jvm and javascript
• you want deep macro and compiler extensibility for language experimentation
• you need glue code across polyglot projects

When to avoid

• you need a production-proven language with a large ecosystem and hiring pool
• you require guaranteed stability, since the language is in beta
• you need first-class tooling, ides, or extensive third-party libraries
• your team has no experience with lisps or advanced type systems
