Name the imports

[complynx]

Instead of

import a.b.c_pb2

some use() -> a.b.c_pb2.Something

do

import a.b.c_pb2 as a_dot_b_dot_c_pb2

some use() -> a_dot_b_dot_c_pb2.Something

as it's done in protoc generator

This would be major feature for us, since we are replacing inserting a package name at start of the imports after files are generated.

Due to ignorance of protobuf adding a package name for python generated code (like protocolbuffers/protobuf#2283) we manually rename like:
import a.b.c_pb2 -> import package_name.a.b.c_pb2

Of course this does not work because of missing alias for imports.

import a.b.c_pb2 as a_dot_b_dot_c_pb2 -> import package_name.a.b.c_pb2 as a_dot_b_dot_c_pb2
would work

Note this used to work in mypy-protobuf 1.24 in the past but for each class import:

from common.decimal_pb2 import (
    Decimal as common___decimal_pb2___Decimal,
)

we changed it to:

from mypackage.common.decimal_pb2 import (
    Decimal as common___decimal_pb2___Decimal,
)
