#grpc

is there a go based grpc cli that uses reflection like the C++ one?

i would rather have something statically linked than have to deal with dependency hell

I added reflection to my grpc server yet grpc_cli still complains about missing imports

I was under the impression reflection means no imports needed

does reflection not properly work with proto imports?

cause it surely doesn't seem to

I just get "[libprotobuf ERROR google/protobuf/descriptor.cc:3457] Invalid proto descriptor for file"

when trying to call a service

it works if I pass the proto paths but that is silly when I enabled reflection

lungaro: No, there isn't such a Go CLI. Go's Protobuf implementation doesn't support "generic message" where is serializes based on a descriptor, which is necessary.

how does the grpc_cli make a descriptor dynamically?

lungaro: That's weird that you're having trouble when using reflection.

C++ and Java have a "generic message" API.

i have .proto files with "import public "...." " in them and it fails on the imports

Oh. I... can believe that.

well grpc_cli works if I properly pass --protofiles and --proto_path

I've seen some other things broken with import public.

:-/

lame

Could you file a bug in grpc/grpc for us to take a look?

the complexity of the DSL always breaks downstream tools

kinda bad experience

Sure

i wonder if go has a generic message api

it probably doesn't eh?

hmm, maybe python. The fact there is reflection is a big step forward

I think I've seen a Go one, but it isn't "official"

lungaro: Here is Java's DynamicMessage for reference:

For Go implementation, see: https://github.com/golang/protobuf/issues/199

I guess it's a "dynamic message" API, not generic message. Meh.

hah

cool

fyi https://github.com/grpc/grpc/issues/13295

hope this is enough info

lungaro: Thanks. That looks reasonable.
