PulsarApi.proto

Getting error with the file PulsarApi.proto:

falanx --inputfile PulsarApi.proto --outputfile Pulsar.Proto.fs --defaultnamespace Pulsar.Proto --serializer binary
Generating code for: PulsarApi.proto
ERROR: proto file was not able to be parsed.

Error in Ln: 55 Col: 11
    optional int32 partition = 3;
          ^

Looks nothing suspect for me on this place:

message MessageIdData {
    required uint64 ledgerId = 1;
    required uint64 entryId  = 2;
    optional int32 partition = 3 [default = -1];
    optional int32 batch_index = 4 [default = -1];
}

Haven't worked this code in forever, but I think the root cause has to do with the core parsing for messages: something was consuming a token and leaving the parser in a bad state.

Can you try PR #107?

@vilinski The commit above was included in release 0.7.2. Can you verify the change worked, so that this issue can be closed?

sorry, waited for falanx updates it's deps.

Falanx 0.6.0 still doesn't work with actual PulsarApi.proto with the parser bug on the same line.

❯ falanx --inputfile PulsarApi.proto --outputfile Pulsar.Proto.fs --defaultnamespace Pulsar.Proto --serializer binary

But type provider works without errors.

#r "nuget: Froto.TypeProvider"

open Froto.TypeProvider

let [<Literal>] PulsarApiProto = __SOURCE_DIRECTORY__ + "/PulsarApi.proto"
type PulsarApi = ProtocolBuffersTypeProvider<PulsarApiProto>

let msg = PulsarApi.Pulsar.Proto.MessageIdData()
msg.Partition <- Some 42

so not a Froto issue anymore.
Rather falanx still does not include the changes (09.04.2020)
