I'll try to implement a simple tool to decompile messages, if I succeed, I
post the solution here.
Thank you

  Hmm, that's true.  Although I'm not sure if there's actual code for

  the .proto file in Java.  In C++, descriptors have a DebugString() method
  which returns a compilable .proto file.

 So it would be a matter of either re-implementing the DebugString in
 Java or dumping out the descriptor from the Java code (after all, it
 is just a proto buffer), re-read that and DebugString it.
 (maybe protoc could have a
 'read-binary-descriptor-and-dump-it-as-protofile' option ;) ).

Generating.proto files from java source file

2009-10-08 Thread grasshopper
Hi all, a guy that isn't working in my company anymore has defined some
protocol buffer messages that we still use. We need to extend these messages
now, but we don't have the .proto file. Is there a straight way to generate
the proto files from the java classes? How could I do this?
Thanks
