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

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