Is it possible to delete one item of a 'repeated' message field (in Python)
I'm building a generic gpb editor, that can create gpb encoded files. The UI is completely dynamic, based on the .proto files that one chooses (http://github.com/bvdeenen/gpbedit/tree/master) In this editor I'm currently generating a gpb object on the fly, but since it's a gui editor, it is necessary to delete one item anywhere in a range of 'repeated' items. Is this currently possible with the python interface (ClearField removes all items of a repeated field)? Or should I hack around it, or maybe have a separate data representation and only build the gpb object when I'm done editting. (That's probably the easiest).

Re: Is it possible to delete one item of a 'repeated' message field (in Python)
I think this was added in rev 90: http://code.google.com/p/protobuf/source/detail?r=90 But it hasn't made it into an official release yet.

Re: Problem with dynamic __import__ of gpb modules
+petar, who may be able to answer this.

Hi
I'm building a generic editor for creating loading and saving gpb
objects and am running into problems with dynamic __import__
statements. I've nailed it down to a very simple testcase. This is all
with python 2.5.2 and protobuf 2.0.3 on Linux.
test.proto:
message test {optional int32 x=1; }
C.py:
class K:
def __init__(self):
print new K
import test_pb2, C
a=getattr(test_pb2,test)
a
class 'test_pb2.test'
b=getattr(C,K)
b
class C.K at 0xb64ceddc
Why is one of the classnames in quotes, and the other not?
When I try a dynamic import I've narrowed my problem down to :
#!/usr/bin/python
def test():
for module,klass in [('test_pb2','test'), ('C', 'K')]:
m=__import__(module)
k=getattr(m, klass)
print *, m, k, type(k)
print k()
test()
Which when run gives me the following
* module 'test_pb2' from 'gpbedit/test_pb2.pyc' class
'test_pb2.test' class
'google.protobuf.reflection.GeneratedProtocolMessageType'
new k=
* module 'C' from '...gpbedit/C.pyc' C.K type 'classobj'
new k= new K
C.K instance at 0xb7d2764c
When I try to create a protocol object of the 'test' type, my python
script returns None.
So where does this go wrong?
Bart
P.S. the editor is at http://github.com/bvdeenen/gpbedit/tree/master.
It's still alpha quality, but it is capable of editing proto objects
and generating a gui from proto files

C++ to Java and vice versa
A Quick newbie question: Can i use Protocol Buffers to serialize in c+ + and deserialize in java? Basically I need to transfer data from a c+ + layer to Java and we were planning to use XML. I was wondering whether Protocol Buffer can be used instead. thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Protocol Buffers group.
