Work with binary ProtoBuf messages based on https://sourceforge.net/projects/protobuf-delphi/files/ by marat1961 (sources have some modifications)

Main features:

• generate classes, not records (like most other parsers)
• cross-platform(???) realization

Limitations:

• no comments in the middle of declaration:

  // this is correct
  message Sample { // this is correct
    // and this too
    repeated // this is NOT supported (comment in the middle of field declaration)
      sint32 Foo = 1;
    optional string FooString = 2; // this is correct

• field types Any and OneOf not supported

• reserved word extensions not supported

• groups (deprecated feature) not supported

How to use

1. add root folder of this project to library path (Tools - Options - Delphi options - Library)
2. open ProtoBufGeneratorGroup.groupproj from root folder of this project
3. compile and run ProtoBufGenerator.exe
4. open .proto file(s) by press "Open" button
5. select directory for new generated .pas file(s) and press "Generate" button
6. add generated file to your project.

Do not use LoadFromBuf/SaveToBuf methods in generated classes! Use LoadFromStream and SaveToStream methods, which inherited from base class. See Example2, how to use generated classes.

ToDo:

• add tests with "original" ProtoBuf generated binary messages.
