protogen golang - finding source line for diagnostics?

[Steve Simon]

Hi,

I am using protogen for go successfully. We are using 

extend google.protobuf.ServiceOptions {  as we need to

encode extra fields for our backend.

When I find typos in the serviceOptions I am parsing I would like to generate diagnostics which reference the source proto file and line number.

I have not found any way to extract the source line number for an object (Service record in my case). Is it possible?

Things like comments and line numbers from the .proto file are represented in the SourceCodeInfo message here. Unfortunately I'm not familiar enough with Go protos or protogen to say exactly how to get ahold of that, but this Location type looks promising.
