Description
What version of CUE are you using (cue version)?
250524b0d6e0a2d64e2be220d55334ef62d65df6
Does this issue reproduce with the latest stable release?
Yes
What did you do?
exec cue import -I . x.proto
exec cat x.cue
exec cue vet -c -d '#StructWrap' x.cue foo.json
-- foo.json --
{
"x": {
"something": true
}
}
-- x.proto --
syntax = "proto3";
package something.v1;
import "google/protobuf/struct.proto";
message StructWrap {
google.protobuf.Struct x = 1;
}
-- google/protobuf/struct.proto --
syntax = "proto3";
package google.protobuf;
option csharp_namespace = "Google.Protobuf.WellKnownTypes";
option cc_enable_arenas = true;
option go_package = "types";
option java_package = "com.google.protobuf";
option java_outer_classname = "StructProto";
option java_multiple_files = true;
option objc_class_prefix = "GPB";
message Struct {
map<string, Value> fields = 1;
}
message Value {
oneof kind {
NullValue null_value = 1;
double number_value = 2;
string string_value = 3;
bool bool_value = 4;
Struct struct_value = 5;
ListValue list_value = 6;
}
}
enum NullValue {
NULL_VALUE = 0;
}
message ListValue {
repeated Value values = 1;
}
What did you expect to see?
A passing test. The google.protobuf.Struct type should allow non-empty structs, but does not.
It should be generating {...} not {}.
What did you see instead?
> exec cue import -I . x.proto
> exec cat x.cue
[stdout]
package v1
#StructWrap: {
x?: {} @protobuf(1,google.protobuf.Struct)
