Combining PyJS and Python-Spidermonkey 

--------------------------------------

pyjs.py is a stand-alone python-to-javascript.  Python-Spidermonkey

provides python bindings to the Netscape / Mozilla spidermonkey javascript

engine.  The combination of the two results in python being compiled

to javascript, and then executed.

pysmrun.py demonstrates how this can be achieved.  It takes as input

as its first argument a filename to be compiled to javascript and

handed to the spidermonkey execution library.

Dependencies

------------

You will require Python-Spidermonkey from this locations:

    http://pypi.python.org/pypi/python-spidermonkey

Follow the build instructions.

Testing

-------

very simple!

echo print "hello" > test.py

./pysmrun.py ./test.py

What's Going On?

----------------

pysmrun.py uses pyjs.py and simply adds pysm as yet another "platform".

Presently, the only function override that's supported is pyjslib.printFunc,

which can be found in pyjamas/library/platform/pyjslibpysm.py and this

simple example is sufficient to demonstrate the principle.

In the pysm-platform-specific version of printFunc, a global routine

named "pysm_print_fn" is called.  This is pre-added, before execution,

to the javascript execution context, as a global, using

python-spidermonkey's "add_global()" function.
