Re: Processing now supports python thanks to Jython

Python mode, including its command-line equivalent, "processing.py", is
built using a patched Jython 2.7. The patch monkeys around with the
semantics of longs, silently downcasting them as needed, in order to
support the use of integer constants as colors (as in 0xAARRGGBB) and other
processing-isms.

https://github.com/jdf/processing.py/blob/master/buildtime/lib/jython/jython-patch.diff

Of course, processing.py adds a bunch of Processing stuff to the global
namespace, too.

https://github.com/jdf/processing.py/blob/master/runtime/src/jycessing/core.py

And it goes through all kinds of crap to allow certain Processing keywords
that intersect with Python builtins to work in either context, mostly found
in
https://github.com/jdf/processing.py/blob/master/runtime/src/jycessing/PAppletJythonDriver.java
.

I hope this helps.
