Proto Schematics

Making Protobuf messages as cute as Python.

Motivation

Protobuf and gRPC are great when it comes to high performance schema aware APIs, but when Google designed Protobuf, it didn't tried to make the generated code idiomatic in Python, which brings a problem when exporting messages outside interface modules. Schematics is a cute and Pythonic schema library that goes well with most applications. Why not join both?

Installing

Using pip:

pip install proto_schamatics

Examples

Inspecting a module is as simple as:

from proto_schematics import ProtobufModule

models = ProtobufModule('my.protobuf.lib').import_schema()
MySchamticsModel = models['ProtobufMessageName']

You can also do it on a lazy lint unfriendly way:

from proto_schematics import ProtobufModule
ProtobufModule('my.protobuf.lib').meta_import()

from protobuf_schematics import ProtobufMessageName as MySchematicsModel

Supports

• Datetimes as native Python
• Duration as TimeDeltas
• Wrappers as native nullable types
