<h1>1 - <a name="1">Introduction</a></h1>
<h2>Goals of Luaj</h2>
Luaj is a lua interpreter based on the 5.1.x line of lua with the following goals in mind:
<ul>
<li>Java-centric implementation to take advantage of native Java features like garbage collection, and a robust class model.
<li>Lightweight to allow for small, fast interpretation of lua bytecode.
<li>Complete set of libraries and tools for integration into real-world projects.
<li>Multi-platform to be able to run on JME, JSE, or JEE environments.
<li>Dependable due to sufficient unit testing of vm and library features.
</ul>
<h1>1 - <a name="1">Simple Examples</a></h1> <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 into Java off-line for JME, and at runtime for JSE.
<li>More alignment with C API (see <a href="names.csv">names.csv</a> for details)
<li>Faster bytecode processing for interpreted code.
<li>Tighter integration between lua and Java layers.
<li>Stackless implementation of interpreted code.
<li>Streamlined processing model with modular interpreter.
<li>More uniform naming of classes.
<li>Better package layout.
<li>Better unit tests of core classes.
</ul>
