I was wondering if there has been any talk or plan to make TextFormat and JsonFormat extensible. For example, we are writing code to log input and output protos for gRPC services. In our case, we need to filter certain sensitive fields (which we currently mark via custom options in the proto file). Ideally, we'd be able to subclass the Printer and use most of the logic in JsonFormat or TextFormat. However, the important methods are currently private, such as:

I was also a little surprised to find that the two Printers don't share an interface, allowing others to more easily add custom printers. Is this something that has come up before? Or maybe we're off the beaten path? Thanks, Paul -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
