protogen | Compile proto3 to generate C code for JSON serialization | JSON Processing library

No Google reference is needed here; you have extended FieldOptions, which is the descriptor metadata type that relates to fields. protobuf-net has an implementation of that in the protobuf-net.Reflection package, in exactly where this could be expected: Google.Protobuf.Reflection.FieldOptions.

However! I doubt that this is going to do what you expect. In this scenario, you have defined a "custom option". Custom options aren't related to runtime instance data - they are part of the .proto DSL, and are usually used to influence code generation; in your case, it would be something like:

Excellent question. I've been meaning to address this area for ages. The answer is a simple "no, I haven't even looked at it". I'd be happy to do so, but reality is that I have limited time and need to prioritise effort on features people are asking for. "Any" is something I've heard basically no noise about, until today. If you have a genuine use case for it, we can probably look. GitHub or email may be a better place to explore it, unless you're happy to handle it simply via byte[] and your own code.

The size of a varint is determined by the value: there is nothing to configure or determine.

As for the sub-objects: instead of using string, use a concrete (non-abstract) class, and you should be fine - just use that type instead of string. The library shows both possibilities because without the schema, it can't be sure which it is, since strings and sub-objects use the same protocol layout. But field 5 could be:

The csharp_out parameter is a folder, not a file, and that isn't how you use proto_path (again, a folder); and it is =, not : - in your case you probably want:

This seems to be a cocoapods issue caused by a recommended build setting. A fix is at CocoaPods/CocoaPods#9905 and targeted for CocoaPods 1.10. As a (temporary) workaround you can set "Quoted include in framework headers" in pods project build settings to NO.

I had similar issues when I switched to pycharm as well. To me is seems like the environment (Project Interpreter) that we selected affects what we install and how. Have to tried to conda install them and see if that works?

There is also a possibility that AquisATP is available only on Linux and not on Windows.

It looks like you've serialized a header, then serialized some other data immediately afterwards, meaning: instead of serializing a SessionLogs that has some SessionLogsDetail records, you've serialized a SessionLogs, and then you've serialized (separately) a SessionLogsDetail - does that sound about right? if so: yes, that will not work correctly; there are ways to do what you're after, but it isn't quite as simple as just serializing one after the other, because the root protobuf object is never terminated; so what actually happens is that it overwrites the root object with later fields by number.

There's two ways of addressing this, depending on the data volume. If the size (including all of the detail rows) is small, you can just change the code so that it is a true parent / child relationship, i.e. so that the rows are all inside the parent. When writing the data, this does not mean that you need to have all the rows before you start writing - there are ways of making appending child rows so that you are sending data as it becomes available; however, when deserializing, it will want to load everything in one go, so this approach is only useful if you're OK with that, i.e. you don't have obscene open-ended numbers of rows.

If you have large numbers of rows, you'll need to add your own framing, essentially. This is often done by adding a length-prefix between each payload, so that you can essentially read a single message at a time. Some of the libraries include helper methods for this; for example, in the java API this is parseDelimitedFrom and writeDelimitedTo. However, my understand is that the python API does not currently support this utility, so you'd need to do the framing yourself :(

To summarize, you currently have:
