[pypy-dev] how can i pickle an application-level object from interpreter code?

[Philip Guo]

Hi all,

I'm brand-new to PyPy, and here is my question: I want to selectively pickle
Python objects that appear in application-level code, from *within* the
interpreter.  e.g., let's say i'm using the PyPy Python interpreter to run
this program:

import foo
x = foo.ComplicatedObject()

right after the interpreter creates an instance of foo.ComplicatedObject(),
I want to serialize that instance to disk, in effect simulating this
statement:

pickle.dump(x, open('data.pickle'))

What is the easiest way for me to do this from within the interpreter code?

It seems like an instance object is represented within the interpreter as of
type "class W_InstanceObject(Wrappable)", and I can't directly pickle that
object.  If I could just call the Python standard library's pickle on 'x'
from within the interpreter, that would be great.

Thanks in advance,
Philip
