Luaj is a pure Java implementation of a Lua interpreter (for versions 5.1 and now 5.2)

  • Java-centric implementation of lua vm built to leverage standard Java features.
  • Lightweight, high performance execution of lua.
  • Multi-platform to be able to run on JME, JSE, or JEE environments.
  • Complete set of libraries and tools for integration into real-world projects.
  • Dependable due to sufficient unit testing of vm and library features.

Luaj is written for JME and JSE, with string, table, package, math, io, os, debug, coroutine & luajava libraries, JSR-223 bindings, all metatags, weak tables and unique direct lua-to-java-bytecode compiling.
