Greetings! The protoc compiler will write a FileDescriptorProto protocol buffer describing its input files when given the --descriptor_set_out flag. If --include_source_info is also given, then comments (and other information) for each element will also be included.
However, any comments at the beginning of the file that are NOT attached to an element will be dropped. I am working on a documentation generator for Protocol Buffers, using the existing plugin infrastructure, and in many cases the leading comments in the file act as an introduction. Therefore, it's important to me that these comments show up in the FileDescriptorProto provided by the compiler. Would you accept a patch that preserves these comments? I have made the changes locally and would be glad to submit it. Justin p.s. To reproduce the issue, I'll use descriptor.proto. Running the following command puts 'descriptor.pb' in /tmp (assuming descriptor.proto is in the current directory): protoc --include_source_info --descriptor_set_out=/tmp/descriptor.pb descriptor.proto descriptor.proto begins with these lines (v2.5.0): // Protocol Buffers - Google's data interchange format // Copyright 2008 Google Inc. All rights reserved. // http://code.google.com/p/protobuf/ And that text is missing from descriptor.pb -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
