[BUG] optional|required fields are no longer a thing in protobuf 3

[smoya]

Describe the bug.

The following is a protobuf3 valid message

message Example {
    string name = 1;
}

As you see, no need for adding optional or required (e.g. required string name = 1;) because such a concept is not present anymore in v3.

However, the parser fails with: illegal token 'string' unless I add optional or required keywords.

Expected behavior

required and optional keywords are not required (I don't even know if they are legal atm?)

This is expected behavior. When ever you not give a hint to the protobuf version. V2 will be assumed.

Please try:

syntax = "proto3";

message Example {
    string name = 1;
}

Makes sense. Thanks for the clarification!
