[protobuf] Re: Why does Protobuf generate outer classes for Java?
Oh okay. So it sounds like many languages, including Java, originally generated code where every message's type was placed into a single generated file (a file per .proto file). For Java, you can only have one public class per file, so the outer class technique was used so that it could be the single public class in the generated file, with each message's class as an inner class within the outer class. But then some users wanted the option of splitting up the generated code, which let to the Java option to use multiple files, in which case there's no need for the outer class technique. So the outer class technique wasn't to enable any specific Protobuf feature, it was just to work around the limitations of Java to make the code look like the code generated when using other languages.

[protobuf] Why does Protobuf generate outer classes for Java?
I googled this and found questions like "How to use Protobuf message as java class without a java outer class?" ( https://stackoverflow.com/questions/60312156/how-to-use-protobuf-message-as-java-class-without-a-java-outer-class) which talk about how one might tweak their Protobuf Java code generation. For example, that person wants to avoid having outer classes. The answer tells them about the "multiple files" option. But I'd like to know why the Java generated code, by default, is split up this way. I didn't notice code split up like that when I used my same Protobuf files to generate Go code. I got just one struct per Protobuf message I defined. In Java, I get two classes per Protobuf message defined, and I can choose between them being nested or in separate files.

[protobuf] C++ Compilation issues propagating from google::protobuf::internal
Hi all, I have been having difficulties trying to compile my project, when integrating protobuf. [image: Capture.PNG] I am using cmake to compile a project that uses the protobuf libraries. I am including protobuf_INCLUDE_DIR in my target include and libprotobuf and libprotobuf in my target link, in my cmakelists. The errors do not make me think any of this is the problem though. The errors do make me wonder if compiler flags are a problem, so I tried adding the '-std=c++11' flag. I thought this worked at first, but it turns out not to be the case. Does anyone have an idea of what the problem might be? Thank you all in advance! -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.

At the request of some of its users, I would like to request that dproto (https://github.com/msoucy/dproto) be added to the list at https://github.com/google/protobuf/wiki/Third-Party-Add-ons under the D programming language. The major reason for the implementation is that the other two implementations listed are no longer under active development and unidiomatic D code, while dproto takes advantage of the language's compile-time computation and reflection capabilities.
