Merge branch 'mc-1.15.x' into mc-1.16.x

No, I don't really know what the difference is either :). Closes #518.

+# Contributing to CC: Tweaked
+As with many open source projects, CC: Tweaked thrives on contributions from other people! This document (hopefully)
+provides an introduction as to how to get started in helping out.
+
+If you've any other questions, [just ask the community][community] or [open an issue][new-issue].
+
+## Reporting issues
+If you have a bug, suggestion, or other feedback, the best thing to do is [file an issue][new-issue]. When doing so,
+do use the issue templates - they provide a useful hint on what information to provide.
+
+## Developing
+In order to develop CC: Tweaked, you'll need to download the source code and then run it. This is a pretty simple
+process. When building on Windows, Use `gradlew.bat` instead of `./gradlew`.
+
+ - **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
+ - **Setup Forge:** `./gradlew build`
+ - **Run Minecraft:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
+
+If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
+These commands may take a few minutes to run the first time, as the environment is set up, but should be much faster
+afterwards.
+
+### Code linters
+CC: Tweaked uses a couple of "linters" on its source code, to enforce a consistent style across the project. While these
+are run whenever you submit a PR, it's often useful to run this before committing.
+
+ - **[Checkstyle]:** Checks Java code to ensure it is consistently formatted. This can be run with `./gradlew build` or
+   `./gradle check`.
+ - **[illuaminate]:** Checks Lua code for semantic and styleistic issues. See [the usage section][illuaminate-usage] for
+   how to download and run it.
+
+## Translations
+Translations are managed through [Weblate], an online interface for managing language strings. This is synced
+automatically with GitHub, so please don't submit PRs adding/changing translations!

-CC: Tweaked is a fork of ComputerCraft which aims to provide earlier access to the more experimental and in-development
-features of the mod. For a more stable experience, I recommend checking out the

+CC: Tweaked is a fork of [ComputerCraft](https://github.com/dan200/ComputerCraft), adding programmable computers,
+turtles and more to Minecraft.
 
 ## What?
-CC: Tweaked (or CC:T for short) does not aim to create a competing fork of ComputerCraft, nor am I planning to take it
-in in a vastly different direction to the original mod. In fact, CC:T aims to be a nurturing ground for various
-features, with a pull request against the original mod being the end goal.
+ComputerCraft has always held a fond place in my heart: it's the mod which really got me into Minecraft, and it's the
+mod which has kept me playing it for many years. However, development of the original mod has slowed, as the original
+developers have had less time to work on the mod, and moved onto other projects and commitments.
 
-CC:T also includes many pull requests from the community which have not yet been merged, offering a large number
-of additional bug fixes and features over the original mod.
+CC: Tweaked (or CC:T for short) is an attempt to continue ComputerCraft's legacy. It's not intended to be a competitor
+to CC, nor do I want to take it in a vastly different direction to the original mod. Instead, CC:T focuses on making the
+ComputerCraft experience as _solid_ as possible, ironing out any wrinkles that may have developed over time.
 
 ## Features
-CC: Tweaked contains the all features of the latest alpha, as well as numerous fixes, performance improvements and
-several additional features. I'd recommend checking out [the releases page](https://github.com/SquidDev-CC/CC-Tweaked/releases)

- - Websocket support in the HTTP library.
- - Wired modems and cables act more like multiparts.
- - Add map-like rendering for pocket computers and printed pages/books.
- - Adds the `/computercraft` command, offering various diagnostic tools for server owners. This allows operators to
-   track which computers are hogging resources, turn on and shutdown multiple computers at once and interact with

- - Add full-block wired modems, allowing one to wrap non-solid peripherals (such as turtles, or chests if Plethora is
+ - Improvements to the `http` library, including websockets, support for other HTTP methods (`PUT`, `DELETE`, etc...)
+   and configurable limits on HTTP usage.
+ - Full-block wired modems, allowing one to wrap non-solid peripherals (such as turtles, or chests if Plethora is
    installed).
+ - Pocket computers can be held like maps, allowing you to view the screen without entering a GUI.
+ - Printed pages and books can be placed in item frames and held like maps.
+ - Several profiling and administration tools for server owners, via the `/computercraft` command. This allows operators
+   to track which computers are hogging resources, turn on and shutdown multiple computers at once and interact with
+   computers remotely.
+ - Closer emulation of standard Lua, adding the `debug` and `io` libraries. This also enables seeking within binary
+   files, meaning you don't need to read large files into memory.
+ - Allow running multiple computers on multiple threads, reducing latency on worlds with many computers.

+Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you want to get started
+developing the mod, [check out the instructions here](CONTRIBUTING.md#developing).
 
-That being said, in order to start helping develop CC:T, you'll need to follow these steps:
+## Community
+If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about
+ComputerCraft we have a [forum](https://forums.computercraft.cc/) and [Discord guild](https://discord.computercraft.cc)!
+There's also a fairly populated, albeit quiet [IRC channel](http://webchat.esper.net/?channels=computercraft), if that's
+more your cup of tea.
 
- - **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
- - **Setup Forge:** `./gradlew setupDecompWorkspace`
- - **Test your changes:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
+I'd generally recommend you don't contact me directly (email, DM, etc...) unless absolutely necessary (i.e. in order to
+report exploits). You'll get a far quicker response if you ask the whole community!
 
-If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
+## Using
+If you want to depend on CC: Tweaked, we have a maven repo. However, you should be wary that some functionality is only
+exposed by CC:T's API and not vanilla ComputerCraft. If you wish to support all variations of ComputerCraft, I recommend
+using [cc.crzd.me's maven](https://cc.crzd.me/maven/) instead.
+
+```groovy
+dependencies {
+  maven { url 'https://squiddev.cc/maven/' }
+}
+
+dependencies {
+  implementation fg.deobf("org.squiddev:cc-tweaked-${mc_version}:${cct_version}")
+}
+```
+
+You should also be careful to only use classes within the `dan200.computercraft.api` package. Non-API classes are
+subject to change at any point. If you depend on functionality outside the API, file an issue, and we can look into
+exposing more features.

-<h1>1 - <a name="1">Introduction</a></h1>
-<h2>Goals of Luaj</h2>
-Luaj is a lua interpreter based on the 5.1.x version of lua with the following goals in mind:
-<ul>
-<li>Java-centric implementation of lua vm built to leverage standard Java features.
-<li>Lightweight, high performance execution of lua. 
-<li>Multi-platform to be able to run on JME, JSE, or JEE environments. 
-<li>Complete set of libraries and tools for integration into real-world projects.
-<li>Dependable due to sufficient unit testing of vm and library features. 
-</ul>
-
-<h2>Differences with 1.0</h2>
-In addition to the basic goals of luaj, version 2.0 is aimed 
-at improving on the 1.0 vm in the following aspects. 
-<ul>
-<li>Support for compiling lua source code into Java source code.
-<li>Support for compiling lua bytecode directly into Java bytecode.
-<li>Improved performance of of lua bytecode processing.
-<li>Stackless vm design centered around dynamically typed objects.
-<li>More alignment with C API (see <a href="names.csv">names.csv</a> for details)
-<li>Improved class and package naming conventions. 
-<li>Improved unit tests of core classes. 
-<li>Improved quality due to major redesign and rewrite of core elements. 
-<li>More complete implementation including weak keys and values, and all metatags. 
-</ul>
-
-<h2>Performance</h2>
-Good performance is a major goal of luaj.  
-The following table provides measured execution times on a subset of benchmarks from 
-<a href="http://shootout.alioth.debian.org/">the computer language benchmarks game</a>  
-in comparison with the standard C distribution.

-Luaj in interpreted mode performs well for the benchmarks, and even better when source-to-source (lua2java) 
-or bytecode-to-bytecode (luajc) compilers are used, 
-and actually executes <em>faster</em> than C-based lua in some cases.  
-It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks tested.  
-
-<h1>2 - <a name="2">Simple Examples</a></h1>
-
-<h2>Run a lua script in Java SE</h2>
-
-<p>
-From the main distribution directory line type:
-
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/hello.lua
-</pre>
-
-<p>
-You should see the following output:
-<pre>
-	hello, world
-</pre>
-
-To see how luaj can be used to acccess most Java API's including swing, try:
-
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
-</pre>
-
-<h2>Compile lua source to lua bytecode</h2>
-
-<p>
-From the main distribution directory line type:
-
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar luac examples/lua/hello.lua
-	java -cp lib/luaj-jse-2.0.3.jar lua luac.out
-</pre>
-
-<p>
-The compiled output "luac.out" is lua bytecode and should run and produce the same result.
-
-<h2>Compile lua source to java source</h2>
-
-<p>
-Luaj can compile to lua source code to Java source code:
-
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar lua2java -s examples/lua -d . hello.lua
-	javac -cp lib/luaj-jse-2.0.3.jar hello.java
-	java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
-</pre>
-
-<p>
-The output <em>hello.java</em> is Java source, that implements the logic in hello.lua directly.
-Once <em>hello.java</em> is compiled into <em>hello.class</em> it can be required and used in place of the original lua script, but with better performance.  
-There are no additional dependencies for compiling or running source-to-source compiled lua. 
-
-<p>
-Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-j</em></b> option when run in JDK 1.5 or higher:
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar lua -j examples/lua/hello.lua
-</pre>
-
-<h2>Compile lua bytecode to java bytecode</h2>
-
-<p>
-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:
-
-<pre>
-	ant bcel-lib
-	java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; luajc -s examples/lua -d . hello.lua
-	java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
-</pre>
-
-<p>
-The output <em>hello.class</em> 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).
-
-<p>
-Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-b</em></b> option and providing the <em>bcel</em> library in the class path:
-<pre>
-	java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; lua -b examples/lua/hello.lua
-</pre>
-
-
-<h2>Run a script in a Java Application</h2>
-
-<p>
-The following pattern is used within Java SE
-
-<pre>
-	import org.luaj.vm2.*;
-	import org.luaj.vm2.lib.jse.*;
-
-	String script = "examples/lua/hello.lua";
-	LuaValue _G = JsePlatform.standardGlobals();
-	_G.get("dofile").call( LuaValue.valueOf(script) );
-</pre>
-
-<p>
-A simple example may be found in
-<pre>
-	examples/jse/SampleJseMain.java
-</pre>
-
-<p>
-You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
-
-<h2>Run a script in a MIDlet</h2>
-
-<p>
-The for MIDlets the <em>JmePlatform</em> is used instead:
-
-<pre>
-	import org.luaj.vm2.*;
-	import org.luaj.vm2.lib.jme.*;
-
-	String script = "examples/lua/hello.lua";
-	LuaValue _G = JmePlatform.standardGlobals();
-	_G.get("dofile").call( LuaValue.valueOf(script) );
-</pre>
-
-<p>
-The file must be a resource within within the midlet jar for <em>dofile()</em> to find it.
-Any files included via <em>require()</em> must also be part of the midlet resources.
-
-<p>
-A simple example may be found in
-<pre>
-	examples/jme/SampleMIDlet.java
-</pre>
-
-<p>
-You must include the library <b>lib/luaj-jme-2.0.3.jar</b> in your midlet jar.
-
-<p>
-An ant script to build and run the midlet is in
-<pre>
-	build-midlet.xml
-</pre>
-
-<p>
-You must install the wireless toolkit and define <em>WTK_HOME</em> for this script to work. 
-
-<h2>Run a script using JSR-223 Dynamic Scripting</h2>
-
-<p>
-The standard use of JSR-223 scripting engines may be used:
-
-<pre>
-	ScriptEngineManager mgr = new ScriptEngineManager();
-	ScriptEngine e = mgr.getEngineByExtension(".lua");
-	e.put("x", 25);
-	e.eval("y = math.sqrt(x)");
-	System.out.println( "y="+e.get("y") );
-</pre>
-
-<p>
-All standard aspects of script engines including compiled statements should be supported.
-
-<p>
-You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
-
-<p>
-A working example may be found in
-<pre>
-	examples/jse/ScriptEngineSample.java
-</pre>
-
-To compile and run it using Java 1.6 or higher:
-
-<pre>
-	javac examples/jse/ScriptEngineSample.java
-	java -cp &quot;lib/luaj-jse-2.0.3.jar;examples/jse&quot; ScriptEngineSample
-</pre>
-
-<h2>Excluding the lua bytecode compiler</h2>
-
-By default, the compiler is included whenever <em>standardGlobals()</em> or <em>debugGlobals()</em> 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.  
-
-<p>
-To exclude the lua-to-lua-bytecode compiler, do not call 
-<em>standardGlobals()</em> or <em>debugGlobals()</em> 
-but instead initialize globals with including only those libraries 
-that are needed and omitting the line:
-<pre>
-	org.luaj.vm2.compiler.LuaC.install();
-</pre>
-
-
-<h2>Including the Lua2Java lua-source-to-Java-source compiler</h2>
-
-<p>
-To compile from lua sources to Java sources for all lua loaded at runtime, 
-install the Lua2Java compiler <em>after</em> globals have been created using:
-
-<pre>
-	org.luaj.vm2.jse.lua2java.Lua2Java.install();
-</pre>
-
-This uses the system Java compiler to compile from Java source to Java bytecode, 
-and cannot compile lua binary files containing lua bytecode at runtime. 
-
-<h2>Including the LuaJC lua-bytecode-to-Java-bytecode compiler</h2>
-
-<p>
-To compile from lua to Java bytecode for all lua loaded at runtime, 
-install the LuaJC compiler <em>after</em> globals have been created using:
-
-<pre>
-	org.luaj.vm2.jse.luajc.LuaJC.install();
-</pre>
-
-<p>
-This will compile all lua bytecode into Java bytecode, regardless of if they are loaded as
-lua source or lua binary files.
-
-<p>
-The requires <em>bcel</em> to be on the class path, and the ClassLoader of JSE or CDC.  
-
-<h1>3 - <a name="3">Concepts</a></h1>
-
-<h2>Globals</h2>
-The old notion of platform has been replaced with creation of globals. 
-Two classes are provided to encapsulate common combinations of libraries.  
-
-<h3>JsePlatform</h3>
-
-This 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.
-
-<h3>JmePlatform</h3>
-
-This 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.
-
-
-<h1>4 - <a name="4">Libraries</a></h1>
-
-<h2>Standard Libraries</h2>
-
-Libraries are coded to closely match the behavior specified in 
-See <a href="http://www.lua.org/manual/5.1/">standard lua documentation</a> for details on the library API's
-
-<p>
-The following libraries are loaded by both <em>JsePlatform.standardGlobals()</em> and <em>JmePlatform.standardGlobals()</em>:
-<pre>	base
-	coroutine
-	io
-	math
-	os
-	package
-	string
-	table
-</pre>
-
-<p>
-The <em>JsePlatform.standardGlobals()</em> globals also include:
-<pre>	luajava 
-</pre>
-
-<p>
-The <em>JsePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobals()</em> functions produce globals that include:
-<pre>	debug
-</pre>
-
-<h3>I/O Library</h3>
-The implementation of the <em>io</em> library differs by platform owing to platform limitations.
-
-<p>
-The <em>JmePlatform.standardGlobals()</em> instantiated the io library <em>io</em> in 
-<pre>
-	src/jme/org/luaj/vm2/lib/jme/JmeIoLib.java
-</pre>
-
-The <em>JsePlatform.standardGlobals()</em> includes support for random access and is in 
-<pre>
-	src/jse/org/luaj/vm2/lib/jse/JseIoLib.java
-</pre>
-
-<h3>OS Library</h3>
-The implementation of the <em>os</em> library also differs per platform.
-
-<p>
-The basic <em>os</em> library implementation us used by <em>JmePlatform</em> and is in:
-<pre>
-	src/core/org/luaj/lib/OsLib.java
-</pre>
-
-A richer version for use by <em>JsePlatform</em> is : 
-<pre>
-	src/jse/org/luaj/vm2/lib/jse/JseOsLib.java
-</pre>
-
-Time is a represented as number of milliseconds since the epoch, 
-and most time and date formatting, locales, and other features 
-are not implemented.
-
-<h3>Coroutine Library</h3>
-The <em>coroutine</em> library is implemented using one JavaThread per coroutine.   
-This allows <em>coroutine.yield()</em> can be called from anywhere, 
-as with the yield-from-anywhere patch in C-based lua. 
-
-<p>
-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 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaThread.html">LuaThread</a>
-and <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/OrphanedThread.html">OrphanedThread</a>
-javadoc for details. 
-
-<h3>Debug Library</h3>
-The <em>debug</em> library is not included by default by 
-<em>JmePlatform.standardGlobals()</em> or <em>JsePlatform.standardGlobsls()</em> .
-
-The functions <em>JmePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobsls()</em> 
-create globals that contain the debug library in addition to the other standard libraries. 
-
-To install dynamically from lua use java-class-based require:</em>:
-<pre>
-	require 'org.luaj.vm2.lib.DebugLib'
-</pre>
-
-The <em>lua</em> command line utility includes the <em>debug</em> library by default.
-
-
-<h3>The Luajava Library</h3>
-The <em>JsePlatform.standardGlobals()</em> includes the <em>luajava</em> library, which simplifies binding to Java classes and methods.  
-It is patterned after the original <a href="http://www.keplerproject.org/luajava/">luajava project</a>.
-
-<p>
-The following lua script will open a swing frame on Java SE:
-<pre>
-	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)
-</pre>
-
-<p>
-See a longer sample in <em>examples/lua/swingapp.lua</em> for details, including a simple animation loop, rendering graphics, mouse and key handling, and image loading. 
-Or try running it using: 
-<pre>
-	java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
-</pre>
-
-<p>
-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. 
-
-<p>
-The <em>lua</em> connand line tool includes <em>luajava</em>.

-<h1>5 - <a name="5">LuaJ API</a></h1>
-
-<h2>API Javadoc</h2>
-The javadoc for the main classes in the LuaJ API are on line at
-<pre>
-	 <a href="http://luaj.sourceforge.net/api/2.0/index.html">http://luaj.sourceforge.net/api/2.0</a>
-</pre>
-
-You can also build a local version from sources using 
-<pre>
-	 ant doc
-</pre>
-
-<h2>LuaValue and Varargs</h2>
-All lua value manipulation is now organized around 
-<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">LuaValue</a>
-which exposes the majority of interfaces used for lua computation.  
-<pre>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">org.luaj.vm2.LuaValue</a>
-</pre>
-
-<h3>Common Functions</h3>
-<em>LuaValue</em> exposes functions for each of the operations in LuaJ.  
-Some commonly used functions and constants include:
-<pre>
-	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	 
-</pre>
-
-<h2>Varargs</h2>
-The interface <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> provides an abstraction for 
-both a variable argument list and multiple return values.  
-For convenience, <em>LuaValue</em> implements <em>Varargs</em> so a single value can be supplied anywhere 
-variable arguments are expected.      
-<pre>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">org.luaj.vm2.Varargs</a>
-</pre>
-
-<h3>Common Functions</h3>
-<em>Varargs</em> exposes functions for accessing elements, and coercing them to specific types:
-<pre>
-	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
-</pre>
- 
-See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> API for a complete list.
- 
-<h2>LibFunction</h2>
-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.   
-<pre>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ZeroArgFunction.html">org.luaj.vm2.lib.ZeroArgFunction</a>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/OneArgFunction.html">org.luaj.vm2.lib.OneArgFunction</a>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/TwoArgFunction.html">org.luaj.vm2.lib.TwoArgFunction</a>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ThreeArgFunction.html">org.luaj.vm2.lib.ThreeArgFunction</a>
-	 <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/VarArgFunction.html">org.luaj.vm2.lib.VarArgFunction</a>
-</pre>
-
-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.
-
-<p>
-For example, to implement a &quot;hello, world&quot; function, we could supply:
-<pre>
-	pubic class hello extends ZeroArgFunction {
-		public LuaValue call() {
-			env.get("print").call(valueOf("hello, world"));
-		}
-	}
-</pre>
-
-The value <em>env</em> is the environment of the function, and is normally supplied 
-by the instantiating object whenever default loading is used. 
-
-<p>
-Calling this function from lua could be done by:
-<pre> 
-	require( 'hello' )()
-</pre>
-
-while calling this function from Java would look like:
-<pre> 
-	new hello().call();
-</pre>
-
-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. 
- 
-<h2>Closures</h2>
-Closures still exist in this framework, but are optional, and are only used to implement lua bytecode execution.  
-
-<h1>6 - <a name="6">Parser</a></h1>
-
-<h2>Javacc Grammar</h2>
-A Javacc grammarwas developed to simplify the creation of Java-based parsers for the lua language.
-The grammar is specified for <a href="https://javacc.dev.java.net/">javacc version 5.0</a> because that tool generates standalone 
-parsers that do not require a separate runtime.     
-
-<p>
-A plain undecorated grammer that can be used for validation is available in <a href="grammar/Lua51.jj">grammar/Lua51.jj</a>
-while a grammar that generates a typed parse tree is in  <a href="grammar/LuaParser.jj">grammar/LuaParser.jj</a>
-
-<h2>Creating a Parse Tree from Lua Source</h2>
-The default lu compiler does a single-pass compile of lua source to lua bytecode, so no explicit parse tree is produced.  
-
-<p>
-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.
-
-<p>
-For example, to parse a file and print all variable names, use code like:
-<pre>
-	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);
-			}
-		} );
-	} 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);
-	}
-</pre> 
-In luaj 2.0.3 error reporting was turned on in the parser so line numbers are avaiable for most parse exceptions.
-This example may be found in
-<pre>
-	examples/jse/SampleParser.java
-</pre>
-
-<p>
-See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/ast/package-summary.html">org.luaj.vm2.ast package</a> javadoc for the API relating to the syntax tree that is produced.

-/**
-* Class to manage loading of {@link Prototype} instances.
-* <p>
-* The {@link LoadState} class exposes one main function, 
-* namely {@link #load(InputStream, String, LuaValue)}, 
-* to be used to load code from a particular input stream.  
-* <p>
-* A simple pattern for loading and executing code is
-* <pre> {@code
-* LuaValue _G = JsePlatform.standardGlobals();
-* LoadState.load( new FileInputStream("main.lua"), "main.lua", _G ).call();
-* } </pre>
-* This should work regardless of which {@link LuaCompiler}
-* has been installed.
-* <p>
-*  
-* Prior to loading code, a compiler should be installed. 
-* <p>
-* By default, when using {@link JsePlatform} or {@JmePlatform}
-* to construct globals, the {@link LuaC} compiler is installed. 
-* <p>
-* To override the default compiler with, say, the {@link LuaJC}
-* lua-to-java bytecode compiler, install it before loading, 
-* for example:
-* <pre> {@code
-* LuaValue _G = JsePlatform.standardGlobals();
-* LuaJC.install();
-* LoadState.load( new FileInputStream("main.lua"), "main.lua", _G ).call();
-* } </pre>

-/**
- * Extension of {@link LuaFunction} which executes lua bytecode. 
- * <p>
- * A {@link LuaClosure} is a combination of a {@link Prototype} 
- * and a {@link LuaValue} to use as an environment for execution. 
- * <p>
- * There are three main ways {@link LuaClosure} instances are created:
- * <ul> 
- * <li>Construct an instance using {@link #LuaClosure(Prototype, LuaValue)}</li>
- * <li>Construct it indirectly by loading a chunk via {@link LuaCompiler#load(java.io.InputStream, String, LuaValue)}
- * <li>Execute the lua bytecode {@link Lua#OP_CLOSURE} as part of bytecode processing
- * </ul>
- * <p>
- * To construct it directly, the {@link Prototype} is typically created via a compiler such as {@link LuaC}:
- * <pre> {@code
- * InputStream is = new ByteArrayInputStream("print('hello,world').getBytes());
- * Prototype p = LuaC.instance.compile(is, "script");
- * LuaValue _G = JsePlatform.standardGlobals()
- * LuaClosure f = new LuaClosure(p, _G);
- * }</pre> 
- * <p>
- * To construct it indirectly, the {@link LuaC} compiler may be used, 
- * which implements the {@link LuaCompiler} interface: 
- * <pre> {@code
- * LuaFunction f = LuaC.instance.load(is, "script", _G);
- * }</pre>
- * <p>
- * Typically, a closure that has just been loaded needs to be initialized by executing it, 
- * and its return value can be saved if needed:
- * <pre> {@code
- * LuaValue r = f.call();
- * _G.set( "mypkg", r ) 
- * }</pre>
- * <p> 
- * In the preceding, the loaded value is typed as {@link LuaFunction} 
- * to allow for the possibility of other compilers such as {@link LuaJC}
- * producing {@link LuaFunction} directly without 
- * creating a {@link Prototype} or {@link LuaClosure}.
- * <p> 
- * Since a {@link LuaClosure} is a {@link LuaFunction} which is a {@link LuaValue}, 
- * all the value operations can be used directly such as:
- * <ul>
- * <li>{@link LuaValue#setfenv(LuaValue)}</li>
- * <li>{@link LuaValue#call()}</li>
- * <li>{@link LuaValue#call(LuaValue)}</li>
- * <li>{@link LuaValue#invoke()}</li>
- * <li>{@link LuaValue#invoke(Varargs)}</li>
- * <li>{@link LuaValue#method(String)}</li>
- * <li>{@link LuaValue#method(String,LuaValue)}</li>
- * <li>{@link LuaValue#invokemethod(String)}</li>
- * <li>{@link LuaValue#invokemethod(String,Varargs)}</li>

-/**
- * Subclass of {@link LuaValue} for representing lua strings.

- * Because lua string values are more nearly sequences of bytes than 
- * sequences of characters or unicode code points, the {@link LuaString}
- * implementation holds the string value in an internal byte array.  
- * <p>
- * {@link LuaString} values are generally not mutable once constructed, 
- * so multiple {@link LuaString} values can chare a single byte array.
- * <p>
- * Currently {@link LuaString}s are pooled via a centrally managed weak table.
- * To ensure that as many string values as possible take advantage of this, 
- * Constructors are not exposed directly.  As with number, booleans, and nil, 
- * instance construction should be via {@link LuaValue#valueOf(byte[])} or similar API.
- * <p>
- * When Java Strings are used to initialize {@link LuaString} data, the UTF8 encoding is assumed. 
- * The functions 
- * {@link LuaString#lengthAsUtf8(char[]),
- * {@link LuaString#encodeToUtf8(char[], byte[], int)}, and 
- * {@link LuaString#decodeAsUtf8(byte[], int, int) 
- * are used to convert back and forth between UTF8 byte arrays and character arrays.

- * {@link #istable()}, 
- * {@link #checktable()}, or
- * {@link #opttable(LuaTable)}

- * <li>{@link #set(LuaValue,LuaValue)}</li>  
- * <li>{@link #rawget(LuaValue)}</li>  
- * <li>{@link #rawset(LuaValue,LuaValue)}</li>
- * <li>plus overloads such as {@link #get(String)}, {@link #get(int)}, and so on</li>  
- * </ul>
- * <p>
- * To iterate over key-value pairs from Java, use
- * <pre> {@code
- * LuaValue k = LuaValue.NIL;
- * while ( true ) {

- * <p>
- * A LuaThread is typically created in response to a scripted call to 
- * {@code coroutine.create()}
- * <p>
- * The threads must be initialized with the globals, so that 
- * the global environment may be passed along according to rules of lua. 
- * This is done via a call to {@link #setGlobals(LuaValue)} 
- * at some point during globals initialization.
- * See {@link BaseLib} for additional documentation and example code.  
- * <p> 
- * The utility classes {@link JsePlatform} and {@link JmePlatform} 
- * see to it that this initialization is done properly.  
- * For this reason it is highly recommended to use one of these classes
- * when initializing globals. 
- * <p>
- * The behavior of coroutine threads matches closely the behavior 
- * of C coroutine library.  However, because of the use of Java threads 
- * to manage call state, it is possible to yield from anywhere in luaj. 
- * <p>
- * Each Java thread wakes up at regular intervals and checks a weak reference
- * to determine if it can ever be resumed.  If not, it throws 
- * {@link OrphanedThread} which is an {@link java.lang.Error}. 
- * Applications should not catch {@link OrphanedThread}, because it can break
- * the thread safety of luaj.

-/** 
- * Subclass of {@link LibFunction} which implements the lua basic library functions. 
- * <p>
- * This contains all library functions listed as "basic functions" in the lua documentation for JME. 
- * The functions dofile and loadfile use the 
- * {@link #FINDER} instance to find resource files.
- * Since JME has no file system by default, {@link BaseLib} implements 
- * {@link ResourceFinder} using {@link Class#getResource(String)}, 
- * which is the closest equivalent on JME.     
- * The default loader chain in {@link PackageLib} will use these as well.
- * <p>  
- * To use basic library functions that include a {@link ResourceFinder} based on 
- * directory lookup, use {@link JseBaseLib} instead. 
- * <p>
- * Typically, this library is included as part of a call to either 
- * {@link JmePlatform#standardGlobals()}
- * <p>
- * To instantiate and use it directly, 
- * link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
- * <pre> {@code
- * LuaTable _G = new LuaTable();
- * LuaThread.setGlobals(_G);
- * _G.load(new BaseLib());
- * _G.get("print").call(LuaValue.valueOf("hello, world"));
- * } </pre>
- * Doing so will ensure the library is properly initialized 
- * and loaded into the globals table. 
- * <p>
- * This is a direct port of the corresponding library in C.

-/** 
- * Abstract base class extending {@link LibFunction} which implements the 
- * core of the lua standard {@code io} library.   
- * <p> 
- * It contains the implementation of the io library support that is common to
- * the JSE and JME platforms. 
- * In practice on of the concrete IOLib subclasses is chosen:  
- * {@link org.luaj.vm2.lib.jse.JseIoLib} for the JSE platform, and 
- * {@link org.luaj.vm2.lib.jme.JmeIoLib} for the JME platform.
- * <p>
- * The JSE implementation conforms almost completely to the C-based lua library, 
- * while the JME implementation follows closely except in the area of random-access files, 
- * which are difficult to support properly on JME. 
- * <p> 
- * Typically, this library is included as part of a call to either 
- * {@link JsePlatform#standardGlobals()} or {@link JmePlatform#standardGlobals()}
- * <p>
- * To instantiate and use it directly, 
- * link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
- * <pre> {@code

-/**
- * Subclass of {@link LuaFunction} common to Java functions exposed to lua. 
- * <p>
- * To provide for common implementations in JME and JSE, 
- * library functions are typically grouped on one or more library classes
- * and an opcode per library function is defined and used to key the switch
- * to the correct function within the library.  
- * <p>
- * Since lua functions can be called with too few or too many arguments, 
- * and there are overloaded {@link LuaValue#call()} functions with varying 
- * number of arguments, a Java function exposed in lua needs to handle  the
- * argument fixup when a function is called with a number of arguments 
- * differs from that expected.  
- * <p>
- * To simplify the creation of library functions, 
- * there are 5 direct subclasses to handle common cases based on number of 
- * argument values and number of return return values.
- * <ul>
- * <li>{@link ZeroArgFunction}</li>
- * <li>{@link OneArgFunction}</li>
- * <li>{@link TwoArgFunction}</li>
- * <li>{@link ThreeArgFunction}</li>
- * <li>{@link VarArgFunction}</li>
- * </ul>
- * <p>
- * To be a Java library that can be loaded via {@code require}, it should have 
- * a public constructor that returns a {@link LuaValue} that, when executed, 
- * initializes the library. 
- * <p> 
- * For example, the following code will implement a library called "hyperbolic" 
- * with two functions, "sinh", and "cosh":
- <pre> {@code 
- * import org.luaj.vm2.LuaValue;
- * import org.luaj.vm2.lib.OneArgFunction;
- * 
- * public class hyperbolic extends OneArgFunction {
- *
- *	public hyperbolic() {}
- *
- *	public LuaValue call(LuaValue libname) {
- *		LuaValue library = tableOf();
- *		library.set( "sinh", new sinh() );
- *		library.set( "cosh", new cosh() );
- *		env.set( "hyperbolic", library );
- *		return library;
- *	}
- *
- *	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()));
- *		}
- *	}
- *}
- *}</pre>
- * The default constructor is used to instantiate the library 
- * in response to {@code require 'hyperbolic'} statement,
- * provided it is on Javas class path. 
- * This instance is then invoked with the name supplied to require() 
- * as the only argument, and library should initialized whatever global
- * data it needs to and place it into the environment if needed.
- * In this case, it creates two function, 'sinh', and 'cosh', and puts 
- * them into a global table called 'hyperbolic.'
- * It placed the library table into the globals via the {@link #env} 
- * local variable which corresponds to the globals that apply when the
- * library is loaded.
- * <p>
- * To test it, a script such as this can be used:
- * <pre> {@code
- * local t = require('hyperbolic')
- * print( 't', t )
- * print( 'hyperbolic', hyperbolic )
- * for k,v in pairs(t) do
- * 	print( 'k,v', k,v )
- * end
- * print( 'sinh(.5)', hyperbolic.sinh(.5) )
- * print( 'cosh(.5)', hyperbolic.cosh(.5) )
- * }</pre> 
- * <p>
- * It should produce something like:
- * <pre> {@code
- * t	table: 3dbbd23f
- * hyperbolic	table: 3dbbd23f
- * k,v	cosh	function: 3dbbd128
- * k,v	sinh	function: 3dbbd242
- * sinh(.5)	0.5210953
- * cosh(.5)	1.127626
- * }</pre> 
- * <p> 
- * See the source code in any of the library functions 
- * such as {@link BaseLib} or {@link TableLib} for other examples.

- * Subclass of {@link LibFunction} which implements the lua standard {@code math}

- * <p> 
- * It contains only the math library support that is possible on JME.  
- * For a more complete implementation based on math functions specific to JSE 
- * use {@link org.luaj.vm2.lib.jse.JseMathLib}. 
- * In Particular the following math functions are <b>not</b> implemented by this library:
- * <ul>
- * <li>acos</li>
- * <li>asin</li>
- * <li>atan</li>
- * <li>cosh</li>
- * <li>log</li>
- * <li>log10</li>
- * <li>sinh</li>
- * <li>tanh</li>
- * <li>atan2</li>
- * </ul>
- * <p>
- * The implementations of {@code exp()} and {@code pow()} are constructed by 
- * hand for JME, so will be slower and less accurate than when executed on the JSE platform.
- * <p> 
- * Typically, this library is included as part of a call to either 
- * {@link JmePlatform#standardGlobals()}
- * <p>
- * To instantiate and use it directly, 
- * link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
- * <pre> {@code
- * LuaTable _G = new LuaTable();
- * LuaThread.setGlobals(_G);
- * _G.load(new BaseLib());
- * _G.load(new PackageLib());
- * _G.load(new MathLib());
- * System.out.println( _G.get("math").get("sqrt").call( LuaValue.valueOf(2) ) );
- * } </pre>
- * Doing so will ensure the library is properly initialized 
- * and loaded into the globals table. 
- * <p>
- * This has been implemented to match as closely as possible the behavior in the corresponding library in C.

-/** 
- * Subclass of {@link LibFunction} which implements the lua standard package and module 
- * library functions. 
- * 
- * <p>
- * Typically, this library is included as part of a call to either 
- * {@link JsePlatform#standardGlobals()} or {@link JmePlatform#standardGlobals()}
- * <p>
- * To instantiate and use it directly, 
- * link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
- * <pre> {@code
- * LuaTable _G = new LuaTable();
- * LuaThread.setGlobals(_G);
- * _G.load(new BaseLib());
- * _G.load(new PackageLib());
- * System.out.println( _G.get("require").call(LuaValue.valueOf("hyperbolic")) );
- * } </pre>
- * In practice, the first 4 lines of the above are minimal requirements to get 
- * and initialize a globals table capable of basic reqire, print, and other functions, 
- * so it is much more convenient to use the {@link JsePlatform} and {@link JmePlatform} 
- * utility classes instead.  
- * <p>
- * This has been implemented to match as closely as possible the behavior in the corresponding library in C.
- * However, the default filesystem search semantics are different and delegated to the bas library 
- * as outlined in the {@link BaseLib} and {@link JseBaseLib} documetnation.

-	 *

-	 *  
-	 * First require queries package.preload[modname]. If it has a value, this value 
-	 * (which should be a function) is the loader. Otherwise require searches for a Lua loader 
-	 * using the path stored in package.path. If that also fails, it searches for a C loader 
-	 * using the path stored in package.cpath. If that also fails, it tries an all-in-one loader 
-	 * (see package.loaders).
-	 * 
-	 * Once a loader is found, require calls the loader with a single argument, modname. 
-	 * If the loader returns any value, require assigns the returned value to package.loaded[modname]. 
-	 * If the loader returns no value and has not assigned any value to package.loaded[modname], 
-	 * then require assigns true to this entry. In any case, require returns the final value of 
-	 * package.loaded[modname].

-	 * the module, then require signals an error.

-/** The {@link JmePlatform} class is a convenience class to standardize 
- * how globals tables are initialized for the JME platform. 
- * <p>
- * The JME platform, being limited, cannot implement all libraries in all aspects.  The main limitations are
- * <ul>
- * <li>Some math functions are not implemented, see {@link MathLib} for details</li>
- * <li>Scripts are loaded via Class.getResourceAsStream(), see {@link BaseLib} for details</li>
- * <li>OS functions execute(), remove(), rename(), and tmpname() vary, see {@link OsLib} for details</li>
- * <li>I/O seek is not implemented, see {@link JmeIoLib} for details</li>
- * <li>luajava is not available, see {@link LuajavaLib} for details</li>
- * </ul>
- * <p>
- * It is used to allocate either a set of standard globals using 
- * {@link #standardGlobals()} or debug globals using {@link #debugGlobals()}
- * <p>
- * A simple example of initializing globals and using them from Java is:
- * <pre> {@code
- * LuaValue _G = JmePlatform.standardGlobals();
- * _G.get("print").call(LuaValue.valueOf("hello, world"));
- * } </pre>
- * <p>
- * Once globals are created, a simple way to load and run a script is:
- * <pre> {@code
- * LoadState.load( getClass().getResourceAsStream("main.lua"), "main.lua", _G ).call();
- * } </pre>
- * <p>
- * although {@code require} could also be used: 
- * <pre> {@code
- * _G.get("require").call(LuaValue.valueOf("main"));
- * } </pre>
- * For this to succeed, the file "main.lua" must be a resource in the class path.
- * See {@link BaseLib} for details on finding scripts using {@link ResourceFinder}.
- * <p>
- * The standard globals will contain all standard libraries in their JME flavors:
- * <ul>
- * <li>{@link BaseLib}</li>
- * <li>{@link PackageLib}</li>
- * <li>{@link TableLib}</li>
- * <li>{@link StringLib}</li>
- * <li>{@link CoroutineLib}</li>
- * <li>{@link MathLib}</li>
- * <li>{@link JmeIoLib}</li>
- * <li>{@link OsLib}</li>
- * </ul>
- * In addition, the {@link LuaC} compiler is installed so lua files may be loaded in their source form. 
- * <p> 
- * The debug globals are simply the standard globals plus the {@code debug} library {@link DebugLib}.
- * <p>
- * <p>
- * The class ensures that initialization is done in the correct order, 
- * and that linkage is made  to {@link LuaThread#setGlobals(LuaValue)}. 
- * @see JsePlatform
- * @see LoadState
