Does protogen.exe support options of protobuf messages? #156

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I use protogen.exe to generate .cs files from .proto files, but the options are 
missing, eg.

message MyMessage {
    option (my_option) = ...;
}

I can not see my_option in the generated .cs file.Has this feature been 
implemented? If so, how to enable it?
thx.

Not currenty. This could potentially be done via clr attributes, but it isn't 
something I've looked at hugely. Do you have a specific scenario in mind?

I'm working on a cross-language project, we intended to serialize/deserialize 
via the typeid specified in the option. eg:
message MyMessage {
    option (type_id) = 37;
    ...
}
when the message being sent, the type_id is automatically written to the 
package header,which can help the remote receiver deserialize it.Is there any 
better option?

Hey Marc, I'm currently running head-long into this issue, and was wondering if 
you'd rethunk your stance on adding support for option in protobuf.net - 
alternatively, was wondering what approach you might have in mind for it (and 
whether you'd be willing to accept an outside patch to add support?)

(more context) Specifically, I'm in almost the exact same scenario: a common 
imported proto file that extends to include an optional "message type id", 
which is set in each actual message proto file via "option 
(foo.message_type_id) = 42;"
