Convert gRPC .proto files to Apache .avro files

Quickstart

The purpose of this module is to convert Google Protocol Buffer files to Apache Avro files. The following example demonstrates how to use the parser:

$ python parser.py -f helloworld.proto --out helloworld.avro

Given that the input file is helloworld.proto:

message HelloRequest {
  string name = 1;
}

message HelloReply {
  string message = 1;
}

The output will be helloworld.avro:

[
    {
        "type": "record",
        "name": "HelloRequest",
        "fields": [
            {
                "type": "String",
                "name": "name"
            }
        ]
    },
    {
        "type": "record",
        "name": "HelloReply",
        "fields": [
            {
                "type": "String",
                "name": "message"
            }
        ]
    }
