[protobuf] Re: Why does protoc convert properties name with 'Url' suffix to 'URL' when converting Objective-C?
The protos style guide for fields:
https://developers.google.com/protocol-buffers/docs/style#message_and_field_names
> Use underscore_separated_names for field names (including oneof field and
extension names) – for example, song_name
To make the generated ObjC code a better fit for ObjC conventions, it
attempts break things apart into the segments and apply Apple's naming
guidelines when building the names. Those include turning some acronym
into allcaps.

[protobuf] How to get a field object using name in proto3 like MutableExtension
Hello everyone,
Intro: My company is in the process of migrating schemas from proto2 to
proto3. I am eliminating extensions as they are not supported.
Question: I am wondering if it is possible to get a field object using it's
name.
Example: In proto2, my current code looks like this:
*> Foo.proto*
message Foo {
message Bar {
unint32 a = 1;
}
extend Foo {
Bar b = 1;
}
}
*> in C++*
*Foo::Bar b_val = foo.MutableExtension(Foo::b);*
Now in proto3, I could do this:
*> Foo.proto*
syntax="proto3";
message Foo {
message Bar {
unint32 a = 1;
}
Bar b = 1;
}
*> in C++*
*Foo::Bar b_val = foo.mutable_b();*
However, I want to use the name Foo::b to get a Foo::Bar object. Is there a
way to do this? If there is, which one is recommended?
Thanks,
Mihir
