+- Java 25 +- Maven 3.9+ -Luaj in interpreted mode performs well for the benchmarks, and even better when -the lua-to-java-bytecode (luajc) compiler is used, -and actually executes faster than C-based lua in some cases. -It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks tested. +The repository includes a Maven Wrapper: -

2 - Examples

+- Windows: `mvnw.cmd` +- Unix-like shells: `./mvnw` -

Run a lua script in Java SE

+## Build -

-From the main distribution directory line type: +Build all modules: -

-	java -cp luaj-jse-3.0.2.jar lua examples/lua/hello.lua
-
+```powershell +.\mvnw.cmd clean package +``` -

-You should see the following output: -

-	hello, world
-
+Run the full test suite: -To see how luaj can be used to acccess most Java API's including swing, try: +```powershell +.\mvnw.cmd clean test +``` -
-	java -cp luaj-jse-3.0.2.jar lua examples/lua/swingapp.lua
-
+Build a single module with dependencies: -

-Links to sources:

-	examples/lua/hello.lua
-	examples/lua/swingapp.lua
-
+```powershell +.\mvnw.cmd -pl jse -am package +``` -

Compile lua source to lua bytecode

+## Quick Start -

-From the main distribution directory line type: +Minimal JSE embedding example: -

-	java -cp luaj-jse-3.0.2.jar luac examples/lua/hello.lua
-	java -cp luaj-jse-3.0.2.jar lua luac.out
-
- -

-The compiled output "luac.out" is lua bytecode and should run and produce the same result. - - -

Compile lua source or bytecode to java bytecode

- -

-Luaj can compile lua sources or binaries directly to java bytecode if the bcel library is on the class path. From the main distribution directory line type: - -

-	ant bcel-lib
-	java -cp "luaj-jse-3.0.2.jar;lib/bcel-5.2.jar" luajc -s examples/lua -d . hello.lua
-	java -cp "luaj-jse-3.0.2.jar;." lua -l hello
-
- -

-The output hello.class is Java bytecode, should run and produce the same result. -There is no runtime dependency on the bcel library, -but the compiled classes must be in the class path at runtime, unless runtime jit-compiling via luajc and bcel are desired (see later sections). - -

-Lua scripts can also be run directly in this mode without precompiling using the lua command with the -b option and providing the bcel library in the class path: -

-	java -cp "luaj-jse-3.0.2.jar;lib/bcel-5.2.jar" lua -b examples/lua/hello.lua
-
- - -

Run a script in a Java Application

- -

-A simple hello, world example in luaj is: - -

-	import org.luaj.vm2.*;
-	import org.luaj.vm2.libs.jse.*;
-
-	Globals globals = JsePlatform.standardGlobals();
-	LuaValue chunk = globals.load("print 'hello, world'");
-	chunk.call();
-	
-
- -Loading from a file is done via Globals.loadFile(): - -
-	LuaValue chunk = globals.loadfile("examples/lua/hello.lua");
-
- -Chunks can also be loaded from a Reader as text source - -
-	chunk = globals.load(new StringReader("print 'hello, world'"), "main.lua");
-
- -or an InputStream to be loaded as text source "t", or binary lua file "b": - -
-	chunk = globals.load(new FileInputSStream("examples/lua/hello.lua"), "main.lua", "bt"));
-
- -

-A simple example may be found in -

-	examples/jse/SampleJseMain.java
-
- -

-You must include the library luaj-jse-3.0.2.jar in your class path. - -

Run a script in a MIDlet

- -

-For MIDlets the JmePlatform is used instead: - -

-	import org.luaj.vm2.*;
-	import org.luaj.vm2.libs.jme.*;
-
-	Globals globals = JmePlatform.standardGlobals();
-	LuaValue chunk = globals.loadfile("examples/lua/hello.lua");
-	chunk.call();
-
- -

-The file must be a resource within within the midlet jar for the loader to find it. -Any files included via require() must also be part of the midlet resources. - -

-A simple example may be found in -

-	examples/jme/SampleMIDlet.java
-
- -

-You must include the library luaj-jme-3.0.2.jar in your midlet jar. - -

- -

-You must install the wireless toolkit and define WTK_HOME for this script to work. - -

Run a script using JSR-223 Dynamic Scripting

- -

-The standard use of JSR-223 scripting engines may be used: - -

-	ScriptEngineManager mgr = new ScriptEngineManager();
-	ScriptEngine e = mgr.getEngineByName("luaj");
-	e.put("x", 25);
-	e.eval("y = math.sqrt(x)");
-	System.out.println( "y="+e.get("y") );
-
- -You can also look up the engine by language "lua" or mimetypes "text/lua" or "application/lua". - -

-All standard aspects of script engines including compiled statements are supported. - -

-You must include the library luaj-jse-3.0.2.jar in your class path. - -

-A working example may be found in -

-	examples/jse/ScriptEngineSample.java
-
- -To compile and run it using Java 1.6 or higher: - -
-	javac -cp luaj-jse-3.0.2.jar examples/jse/ScriptEngineSample.java
-	java -cp "luaj-jse-3.0.2.jar;examples/jse" ScriptEngineSample
-
- -

Excluding the lua bytecode compiler

- -By default, the compiler is included whenever standardGlobals() or debugGlobals() are called. -Without a compiler, files can still be executed, but they must be compiled elsewhere beforehand. -The "luac" utility is provided in the jse jar for this purpose, or a standard lua compiler can be used. - -

-To exclude the lua-to-lua-bytecode compiler, do not call -standardGlobals() or debugGlobals() -but instead initialize globals with including only those libraries -that are needed and omitting the line: -

-	org.luaj.vm2.compiler.LuaC.install(globals);
-
- - -

Including the LuaJC lua-bytecode-to-Java-bytecode compiler

- -

-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. - -

-The requires bcel to be on the class path, and the ClassLoader of JSE or CDC. - -

3 - Concepts

- -

Globals

-The old notion of platform has been replaced with creation of globals. -The Globals -class holds global state needed for executing closures as well as providing -convenience functions for compiling and loading scripts. - -

Platform

-To simplify construction of Globals, and encapsulate differences needed to support -the diverse family of Java runtimes, luaj uses a Platform notion. -Typically, a platform is used to construct a Globals, which is then provided as a global -environment for client scripts. - -

JsePlatform

-The JsePlatform -class can be used as a factory for globals in a typical Java SE application. -All standard libraries are included, as well as the luajava library. -The default search path is the current directory, -and the math operations include all those supported by Java SE. - -

Android

- -Android applications should use the JsePlatform, and can include the Luajava library -to simplify access to underlying Android APIs. -A specialized Globals.finder should be provided to find scripts and data for loading. -See examples/android/src/android/LuajView.java -for an example that loads from the "res" Android project directory. -The ant build script is examples/android/build.xml. - -

Applet

- -Applets in browsers should use the JsePlatform. The permissions model in applets is -highly restrictive, so a specialization of the Luajava library must be used that -uses default class loading. This is illustrated in the sample Applet -examples/jse/SampleApplet.java, - - -

JmePlatform

-The JmePlatform -class can be used to set up the basic environment for a Java ME application. -The default search path is limited to the jar resources, -and the math operations are limited to those supported by Java ME. -All libraries are included except luajava, and the os, io, and math libraries are -limited to those functions that can be supported on that platform. - -

MIDlet

- -MIDlets require the JmePlatform. -The JME platform has several limitations which carry over to luaj. -In particular Globals.finder is overridden to load as resources, so scripts should be -colocated with class files in the MIDlet jar file. Luajava cannot be used. -Camples code is in -examples/jme/SampleMIDlet.java, - - -

Thread Safety

- -Luaj 3.0 can be run in multiple threads, with the following restrictions: - - -For an example of loading allocating per-thread Globals and invoking scripts in -multiple threads see examples/jse/SampleMultiThreaded.java - -

-As an alternative, the JSR-223 scripting interface can be used, and should always provide a separate Globals instance -per script engine instance by using a ThreadLocal internally. - -

Sandboxing

-Lua and luaj are allow for easy sandboxing of scripts in a server environment. -

-Considerations include -

- -Luaj provides sample code covering various approaches: - - -

4 - Libraries

- -

Standard Libraries

- -Libraries are coded to closely match the behavior specified in -See standard lua documentation for details on the library API's - -

-The following libraries are loaded by both JsePlatform.standardGlobals() and JmePlatform.standardGlobals(): -

	base
-	bit32
-	coroutine
-	io
-	math
-	os
-	package
-	string
-	table
-
- -

-The JsePlatform.standardGlobals() globals also include: -

	luajava 
-
- -

-The JsePlatform.debugGlobals() and JsePlatform.debugGlobals() functions produce globals that include: -

	debug
-
- -

I/O Library

-The implementation of the io library differs by platform owing to platform limitations. - -

-The JmePlatform.standardGlobals() instantiated the io library io in -

-	src/jme/org/luaj/vm2/lib/jme/JmeIoLib.java
-
- -The JsePlatform.standardGlobals() includes support for random access and is in -
-	src/jse/org/luaj/vm2/lib/jse/JseIoLib.java
-
- -

OS Library

-The implementation of the os library also differs per platform. - -

-The basic os library implementation us used by JmePlatform and is in: -

-	src/core/org/luaj/lib/OsLib.java
-
- -A richer version for use by JsePlatform is : -
-	src/jse/org/luaj/vm2/lib/jse/JseOsLib.java
-
- -Time is a represented as number of seconds since the epoch, -and locales are not implemented. - -

Coroutine Library

-The coroutine library is implemented using one JavaThread per coroutine. -This allows coroutine.yield() can be called from anywhere, -as with the yield-from-anywhere patch in C-based lua. - -

-Luaj uses WeakReferences and the OrphanedThread error to ensure that coroutines that are no longer referenced -are properly garbage collected. For thread safety, OrphanedThread should not be caught by Java code. -See LuaThread -and OrphanedThread -javadoc for details. The sample code in examples/jse/CollectingOrphanedCoroutines.java -provides working examples. - -

Debug Library

-The debug library is not included by default by -JmePlatform.standardGlobals() or JsePlatform.standardGlobsls() . - -The functions JmePlatform.debugGlobals() and JsePlatform.debugGlobsls() -create globals that contain the debug library in addition to the other standard libraries. - -To install dynamically from lua use java-class-based require:: -
-	require 'org.luaj.vm2.libs.DebugLib'
-
- -The lua command line utility includes the debug library by default. - - -

The Luajava Library

-The JsePlatform.standardGlobals() includes the luajava library, which simplifies binding to Java classes and methods. -It is patterned after the original luajava project. - -

-The following lua script will open a swing frame on Java SE: -

-	jframe = luajava.bindClass( "javax.swing.JFrame" )
-	frame = luajava.newInstance( "javax.swing.JFrame", "Texts" );
-	frame:setDefaultCloseOperation(jframe.EXIT_ON_CLOSE)
-	frame:setSize(300,400)
-	frame:setVisible(true)
-
- -

-See a longer sample in examples/lua/swingapp.lua for details, including a simple animation loop, rendering graphics, mouse and key handling, and image loading. -Or try running it using: -

-	java -cp luaj-jse-3.0.2.jar lua examples/lua/swingapp.lua
-
- -

-The Java ME platform does not include this library, and it cannot be made to work because of the lack of a reflection API in Java ME. - -

-The lua connand line tool includes luajava. - -

5 - LuaJ API

- -

API Javadoc

-The javadoc for the main classes in the LuaJ API are on line at -
-	 http://luaj.org/luaj/3.0/api
-
- -You can also build a local version from sources using -
-	 ant doc
-
- -

LuaValue and Varargs

-All lua value manipulation is now organized around -LuaValue -which exposes the majority of interfaces used for lua computation. -
-	 org.luaj.vm2.LuaValue
-
- -

Common Functions

-LuaValue exposes functions for each of the operations in LuaJ. -Some commonly used functions and constants include: -
-	call();               // invoke the function with no arguments
-	call(LuaValue arg1);  // call the function with 1 argument
-	invoke(Varargs arg);  // call the function with variable arguments, variable return values
-	get(int index);       // get a table entry using an integer key
-	get(LuaValue key);    // get a table entry using an arbitrary key, may be a LuaInteger
-	rawget(int index);    // raw get without metatable calls
-	valueOf(int i);       // return LuaValue corresponding to an integer
-	valueOf(String s);    // return LuaValue corresponding to a String
-	toint();              // return value as a Java int
-	tojstring();          // return value as a Java String
-	isnil();              // is the value nil
-	NIL;                  // the value nil
-	NONE;                 // a Varargs instance with no values	 
-
- -

Varargs

-The interface Varargs provides an abstraction for -both a variable argument list and multiple return values. -For convenience, LuaValue implements Varargs so a single value can be supplied anywhere -variable arguments are expected. -
-	 org.luaj.vm2.Varargs
-
- -

Common Functions

-Varargs exposes functions for accessing elements, and coercing them to specific types: -
-	narg();                 // return number of arguments
-	arg1();                 // return the first argument
-	arg(int n);             // return the nth argument
-	isnil(int n);           // true if the nth argument is nil
-	checktable(int n);      // return table or throw error
-	optlong(int n,long d);  // return n if a long, d if no argument, or error if not a long
-
- -See the Varargs API for a complete list. - -

LibFunction

-The simplest way to implement a function is to choose a base class based on the number of arguments to the function. -LuaJ provides 5 base classes for this purpose, depending if the function has 0, 1, 2, 3 or variable arguments, -and if it provide multiple return values. -
-	 org.luaj.vm2.libs.ZeroArgFunction
-	 org.luaj.vm2.libs.OneArgFunction
-	 org.luaj.vm2.libs.TwoArgFunction
-	 org.luaj.vm2.libs.ThreeArgFunction
-	 org.luaj.vm2.libs.VarArgFunction
-
- -Each of these functions has an abstract method that must be implemented, -and argument fixup is done automatically by the classes as each Java function is invoked. - -

-An example of a function with no arguments but a useful return value might be: -

-	pubic class hostname extends ZeroArgFunction {
-		public LuaValue call() {
-			return valueOf(java.net.InetAddress.getLocalHost().getHostName());
-		}
-	}
-
- -The value env is the environment of the function, and is normally supplied -by the instantiating object whenever default loading is used. - -

-Calling this function from lua could be done by: -

 
-	local hostname = require( 'hostname' )
-
- -while calling this function from Java would look like: -
 
-	new hostname().call();
-
- -Note that in both the lua and Java case, extra arguments will be ignored, and the function will be called. -Also, no virtual machine instance is necessary to call the function. -To allow for arguments, or return multiple values, extend one of the other base classes. - -

Libraries of Java Functions

-When require() is called, it will first attempt to load the module as a Java class that implements LuaFunction. -To succeed, the following requirements must be met: - - -

-If luaj can find a class that meets these critera, it will instantiate it, cast it to LuaFunction -then call() the instance with two arguments: -the modname used in the call to require(), and the environment for that function. -The Java may use these values however it wishes. A typical case is to create named functions -in the environment that can be called from lua. - -

-A complete example of Java code for a simple toy library is in examples/jse/hyperbolic.java -

+```java
+import org.luaj.vm2.Globals;
 import org.luaj.vm2.LuaValue;
-import org.luaj.vm2.libs.*;
+import org.luaj.vm2.libs.jse.JsePlatform;
 
-public class hyperbolic extends TwoArgFunction {
+Globals globals = JsePlatform.standardGlobals();
+LuaValue chunk = globals.load("print('hello, world')");
+chunk.call();
+```
 
-	public hyperbolic() {}
+## Maven Usage
 
-	public LuaValue call(LuaValue modname, LuaValue env) {
-		LuaValue library = tableOf();
-		library.set( "sinh", new sinh() );
-		library.set( "cosh", new cosh() );
-		env.set( "hyperbolic", library );
-		return library;
-	}
+Use the published modules directly from Maven:
 
-	static class sinh extends OneArgFunction {
-		public LuaValue call(LuaValue x) {
-			return LuaValue.valueOf(Math.sinh(x.checkdouble()));
-		}
-	}
-	
-	static class cosh extends OneArgFunction {
-		public LuaValue call(LuaValue x) {
-			return LuaValue.valueOf(Math.cosh(x.checkdouble()));
-		}
-	}
-}
-
+```xml + + org.openautonomousconnection.luaj + jse + 3.0.2 + +``` -In this case the call to require invokes the library itself to initialize it. The library implementation -puts entries into a table, and stores this table in the environment. +For the core VM without the JSE platform layer: -

-The lua script used to load and test it is in examples/lua/hyperbolicapp.lua -

-	require 'hyperbolic'
+```xml
+
+  org.openautonomousconnection.luaj
+  core
+  3.0.2
+
+```
 
-	print('hyperbolic', hyperbolic)
-	print('hyperbolic.sinh', hyperbolic.sinh)
-	print('hyperbolic.cosh', hyperbolic.cosh)
+## Notable Runtime Notes
 
-	print('sinh(0.5)', hyperbolic.sinh(0.5))
-	print('cosh(0.5)', hyperbolic.cosh(0.5))

+- LuaJ runs on the host JVM garbage collector. Resource cleanup is not equivalent to native Lua finalization. +- Explicit close is still the correct pattern for files, iterators, and host-backed resources. +- `LuaJC` is available on JSE and covered by the current Maven test path. +- JME support remains in the Maven build, with environment-specific limitations depending on available Java ME APIs. -For this example to work the code in hyperbolic.java must be compiled and put on the class path. - -

Closures

-Closures still exist in this framework, but are optional, and are only used to implement lua bytecode execution, -and is generally not directly manipulated by the user of luaj. -

-See the org.luaj.vm2.LuaClosure -javadoc for details on using that class directly. +## Examples -

6 - Parser

+Relevant examples are in: -

Javacc Grammar

-A Javacc grammar was developed to simplify the creation of Java-based parsers for the lua language. -The grammar is specified for javacc version 5.0 because that tool generates standalone -parsers that do not require a separate runtime. +- `examples/jse` +- `examples/jme` +- `examples/lua` +- `examples/maven` -

-A plain undecorated grammer that can be used for validation is available in -grammar/Lua52.jj -while a grammar that generates a typed parse tree is in -grammar/LuaParser.jj +## Status -

Creating a Parse Tree from Lua Source

-The default lu compiler does a single-pass compile of lua source to lua bytecode, so no explicit parse tree is produced. +Current implementation notes for the Lua 5.4 work are tracked in `LUA54_STATUS.md`. -

-To simplify the creation of abstract syntax trees from lua sources, the LuaParser class is generated as part of the JME build. -To use it, provide an input stream, and invoke the root generator, which will return a Chunk if the file is valid, -or throw a ParseException if there is a syntax error. +## License -

-For example, to parse a file and print all variable names, use code like: -

-	try {
-		String file = "main.lua";
-		LuaParser parser = new LuaParser(new FileInputStream(file));
-		Chunk chunk = parser.Chunk();
-		chunk.accept( new Visitor() {
-			public void visit(Exp.NameExp exp) {
-				System.out.println("Name in use: "+exp.name.name
-					+" line "+exp.beginLine
-					+" col "+exp.beginColumn);
-			}
-		} );
-	} catch ( ParseException e ) {
-		System.out.println("parse failed: " + e.getMessage() + "\n"
-			+ "Token Image: '" + e.currentToken.image + "'\n"
-			+ "Location: " + e.currentToken.beginLine + ":" + e.currentToken.beginColumn 
-			         + "-" + e.currentToken.endLine + "," + e.currentToken.endColumn);
-	}
-
- -An example that prints locations of all function definitions in a file may be found in -
-	examples/jse/SampleParser.java
-
- -

-See the org.luaj.vm2.ast package javadoc for the API relating to the syntax tree that is produced. - -

Known Issues

-

Limitations

- -

Garbage Collection And Resources

-LuaJ does not implement the same garbage collector semantics as native Lua. Garbage collection is delegated to the host JVM or CLDC runtime, so collectgarbage() is only a hint and should not be used as a resource-management primitive. -

-In particular: -

-

-Short-lived locals may also remain reachable longer than expected because host stack/register reuse is implementation-dependent. If prompt reclamation matters, isolate temporary allocations in functions and clear large references explicitly instead of assuming block exit is enough. -

File Character Encoding

-Source files can be considered encoded in UTF-8 or ISO-8859-1 and results should be as expected, -with literal string contianing quoted characters compiling to the same byte sequences as the input. - -For a non ASCII-compatible encoding such as EBSDIC, however, there are restrictions: - -These restrictions are mainly a side effect of how the language is defined as allowing byte literals -within literal strings in source files. - -Code that is generated on the fly within lua and compiled with lua's load() function -should work as expected, since these strings will never be represented with the -host's native character encoding. +This project is distributed under the terms in `LICENSE`. diff --git a/core/src/main/java/org/luaj/vm2/LoadState.java b/core/src/main/java/org/luaj/vm2/LoadState.java index 2010eed8..e3841e13 100644 --- a/core/src/main/java/org/luaj/vm2/LoadState.java +++ b/core/src/main/java/org/luaj/vm2/LoadState.java @@ -127,8 +127,10 @@ public class LoadState { public static final String SOURCE_BINARY_STRING = "binary string"; - /** for header of binary files -- this is Lua 5.2 */ - public static final int LUAC_VERSION = 0x52; + /** for header of binary files -- this is Lua 5.4 */ + public static final int LUAC_VERSION = 0x54; + public static final int LUAC_VERSION_53 = 0x53; + public static final int LUAC_VERSION_52 = 0x52; /** for header of binary files -- this is the official format */ public static final int LUAC_FORMAT = 0; @@ -136,6 +138,13 @@ public class LoadState { /** size of header of binary files */ public static final int LUAC_HEADERSIZE = 12; + public static final int LUA_TNUMFLT = LUA_TNUMBER; + public static final int LUA_TSHRSTR = LUA_TSTRING; + public static final int LUA_TNUMINT = LUA_TNUMBER | (1 << 4); + public static final int LUA_TLNGSTR = LUA_TSTRING | (1 << 4); + public static final long LUAC_INT = 0x5678; + public static final double LUAC_NUM = 370.5; + // values read from the header private int luacVersion; private int luacFormat; @@ -143,6 +152,7 @@ public class LoadState { private int luacSizeofInt; private int luacSizeofSizeT; private int luacSizeofInstruction; + private int luacSizeofLuaInteger; private int luacSizeofLuaNumber; private int luacNumberFormat; @@ -165,6 +175,10 @@ public class LoadState { public static void install(Globals globals) { globals.undumper = instance; } + + private boolean isModernVersion() { + return luacVersion == LUAC_VERSION || luacVersion == LUAC_VERSION_53; + } /** Load a 4-byte int value from the input stream * @return the int value laoded. @@ -217,6 +231,19 @@ public class LoadState { * @return the {@link LuaString} value laoded. **/ LuaString loadString() throws IOException { + if (isModernVersion()) { + long size = is.readUnsignedByte(); + if (size == 0) { + return null; + } + if (size == 0xFFL) { + size = this.luacSizeofSizeT == 8 ? loadInt64() : (loadInt() & 0xffffffffL); + } + int len = (int) size - 1; + byte[] bytes = new byte[len]; + is.readFully(bytes, 0, len); + return LuaString.valueUsing(bytes); + } int size = this.luacSizeofSizeT == 8?
