validate.proto is still in proto2, which is not supported by codegen of Ruby

[gongcon]

Protobuf is not going to add support of proto2 in Ruby, see here. The fundamental validate.proto in still in v2. We are not able to generate Ruby code because of that. The goal we are trying achieve is to stream access log to Logslash, which is written in Ruby.

Found another request here: #113. Is there any plan to implement that?

Based on @rodaine's comments in the linked issue, switching from proto2 to proto3 for validate.proto would be both a breaking change for PGV, and not particularly useful towards fixing your issue with the Ruby generator.

validate.proto imports and heavily depends on descriptor.proto, which is itself proto2. Migrating validate.proto to proto3 would not fix your problem. It would only push your problem around.

I think the outgoing data should not have the dependencies back on the configurations. It will resolve my problem if it can be a standalone proto file without such kind of dependencies.

Due to the nature of protobuf extensions, validate.proto and descriptor.proto are inseparable. https://github.com/envoyproxy/protoc-gen-validate/blob/master/validate/validate.proto#L12-L30
