JLua

[ramsdell@... (John D. Ramsdell)]

JLua is an incomplete implementation of Lua in Java similar to Jython
in need of help from volunteers.  You can find the sources at

STATUS

The lexical scanner and the parser are fully functioning.  A past
version was able to correctly print Lua source from the syntax tree
produced by the parser.

The next milestone is to translate Lua into Java source code, write it
to disk, and then compile and load it.  The implementation uses flat
closures.  The variable binding analysis has been completed, however,
only some of the code generators are complete.  The parallel
assignment statement was the last focus of activity.

The final milestone is to translate Lua into Java Bytecode and load
them directly from memory.  In other words, the plan is to write the
translation of Lua functions in classfile format into byte arrays, and
then load them via a tailored classloader.  The particular way in
which Java source is produced for the previous milestone was selected
as it models the bytecode in memory generation model.

My current work responsibilities include no use for Lua, so I find it
hard to allocate time for this project.  This is the reason I am
seeking volunteers.
