pyb -- Main interface.
Load a pyb.DescriptorSet. Create types. Then use the types to decode byte
strings.
TODO: Need encoding. Create a type. Then call encode() on it to create a
byte string.
For Poly, I think I need another interface. No types!
Takes a Dict.
And then a schema.
db = pyb.DescriptorSet.FromBinary('addressbook.desc.encoded')
address_book_pb = db.AllTypes()
address_book_pb.AddressBook.FromDict(
{ person: [
{ name: "Andy",
email: "andy@foo.com"
phone: [
{ number: "123-345-5655"
type: "MOBILE"
},
{ number: "123-345-5655"
type: "WORK"
},
]
},
{ name: "Bob",
email: "bob@foo.com"
}
]
})
# Hm, there already is a ToDict() thing. Is that what you want? Maybe better
# to minimize it.
a = address_book_pb.AddressBook()
d = a.ToDict()
# d is now { "person": }
The thing is that in Poly I don't care about internal Python types. It could
be a simpler interface like:
desc_set = pyb.DescriptorSet("addressbook.desc.encoded")
dict = desc_set.decode("address_book.Person", "some binary data")
encoded = desc_set.encode("address_book.Person", { "foo": 1 })
Do you need the whole Python type tree? It might not be that bad I guess.
Otherwise it calls decoding.DecodePart in the constructor, which does all this
setaddr BS. You don't need that. Just fork decoding.py (again). And write
encoding.py.
raw_decode.py -- Decode without a schema. Move to bin/?
pyb_tool.py -- Command line tool. Maybe move to bin/
TODO
----
- encoding of messages -- somewhat DONE
- encoding needs to check REQUIRED fields! We can create invalid messages now
- enum decoding and encoding
- Tests: copy golden message from protobuf repository
