Aug 3, 2020 · Lua is a C library, you can embed it in Java but you'll have to interface the java virtual machine and Lua with some C code. The LuaJava authors have already done that work - you're better off using that than writing your own. answered Jan 21, 2010 at 22:57. nos.
The Need for Integrating Lua with Java Advantages of Using Lua in Java. Integrating Lua within Java applications provides several benefits: Dynamic Scripting Capabilities: Lua allows developers to modify and execute scripts at runtime, offering flexibility that is not easily achievable with static Java code. Improved Performance in Specific ...
Feb 13, 2012 · 1. One alternative is LuaJava. It allows you to use Lua scripting in Java program. Speaking literally about implementing interfaces in Lua: LuaJava also allows Java to implement an interface using Lua. This way any interface can be implemented in Lua and passed as parameter to any method, and when called, the equivalent function will be called ...

JLua is a scripting tool for Java. This tool allows scripts written in Lua to manipulate components developed in Java and vice versa.
JLua is a fork of "LuaJava". It offers the following improvements:
•Added LuaState wrapper to ease manipulation of lua objects.
•Simpler creation of Java objects from Lua.
•Lua error automatically causes Java exception and vice versa.
•Added "try ... catch ... finally" mechanism to Lua.
First, change your current working directory to the build directory. Then, run cmake:
For 64-bit build run:
On Linux/Mac the default generator is Unix Makefiles, so the build can be started by invoking the make executable:
On Windows the default generator is a Visual Studio project file. You can open the file and build manually or execute the following command from the VS Native Tools command prompt:
This library offers 5 functions:
•jlua.getClass ( class_name )
Get a Java class to lua code. Examples:
•jlua.newArray ( class_name, num_of_elements )
Create new Java array from Lua. Examples:
•jlua.throw ( trowable_or_string )
The "Lua" object offer many methods to manipulate lua objects. See src/java/org/jlua/Console.java for simple usage example.
Lua has been traditionally used as an embedded scripting language. Luna aims to serve a similar purpose on the JVM, with an explicit focus on sandboxing the client Lua programs. There are two main use-cases for Luna: running untrusted Lua scripts on the JVM, and enhancing Java applications by adding the ability to script them with Lua.
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.

jLuaScript is a Java/Lua bridge which allows to execute Lua scripts (through Luaj) in Java, but with access to all classes and the whole Java environment. The main use-case is to allow to write scripts in Lua which have access to the complete Java ecosystem. So what we can do, is import any class we want and use it just like that in our script:
