In general, we don't need to parse or process Pypy object in C code, but
only transfer the object from one Pypy enviroment to another Pypy
enviroment.
I am thinking could we have the alternavtive easier way to do this, like
PyObject in Python?
Could we get the address of the Pypy Object and the le
yes, you need a serializer protocol, like JSON (or protobuf or
anything). You generally need to express stuff in a way C can
understand and read it in python

The problem is we might need to support several kinds of collection
objects: list, dict, tuple.
In addition, we might not know what is exact type of objects stored in the
collections. A list might store int, string, double.
So it might involve a lot of work to write the python wrapper.
Do you have
you really can't convert it to the C stuff like that. You need to do:
foo = ffi.new("int[]", 13)
foo[0] = 12
foo[1] = 55
etc.
You can write nice python wrapper around those things too, if the data
is too bare bone.

Hi Maciej,
Could you provide some details on how to use cffi buffers? (a simple demo
code or documents)
I tried the below code but it did not work.
#python list
x=[1,2,3,4]
#intend to convert to c++ char*, but failed
p=ffi.from_buffer(x)
#intend to covert back to python list, but failed
y=ffi.buf
Can't you use pickle or the json module?
Cheers,
Carl Friedrich

you can use cffi buffers (e.g. cffi char*) that you manipulate from
python using wrappers. They would behave (sort of) like python objects
and the wrapper code is really not a performance penalty in most cases

Hi,
Are there any good methods to serialize Pypy object to C++ char* and
deserialize to Pypy object from C++ char*?
Our scenario like this:
We have at least two C++ process running, and each process embeded Pypy to
execute some functions.
And we woule like to reuse Pypy object from one process t
