To compile from lua to Java bytecode for all lua loaded at runtime, install the LuaJC compiler into a globals object use: org.luaj.vm2.jse.luajc.LuaJC.install(globals); This will compile all lua bytecode into Java bytecode, regardless of if they are loaded as lua source or lua binary files.
Dec 10, 2018 · Java follows a more verbose syntax with a strong emphasis on object-oriented programming principles. On the other hand, Lua has a more lightweight and flexible syntax, making it suitable for scripting and embedding into other applications. Typing: Another difference lies in the typing system of both languages.
The Java Virtual Machine (JVM) is a close analogue to the Lua VM – both are bytecode VMs. A difference we can ignore here is that the JVM is a stack machine, so the JVM instruction set operates implicitly on the values at the top of its stack, not registers.
It also bypasses the overhead of the full Java compiler, so is suitable for dynamic script-to-bytecode compiling in most Java environments. Naturally, the compiled bytecode includes support for closures, metatables, and all standard features of the lua language, even though the underlying Java runtime does not. For more details see the luaj ...
Jul 31, 2015 · 2. Lua is just insane fast with JIT compiling by LuaJIT, the reference implementation (also known as CLua) is fast too but no match for JIT compiled Java. LuaJ can compile Lua to Java bytecode but not as effective as Java to bytecode because the Java language is nearer to hardware architecture and thus results in faster machine code. Using LuaJ ...
Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics.

About. Luna is an implementation of Lua 5.3 for the Java Virtual Machine (JVM), written in pure Java with minimal dependencies. The goal of the Luna project is to develop a correct, complete and scalable Lua implementation for running sandboxed Lua programs on the JVM. Luna implements Lua 5.3 as specified by the Lua Reference Manual, explicitly ...
