ProtoBuf.jl

This is a Julia package that provides a compiler and a codec for Protocol Buffers.

Protocol Buffers are a language-neutral, platform-neutral extensible mechanism for serializing structured data.

Example

Given a test.proto file in your current working directory:

syntax = "proto3";

message MyMessage {
    sint32 a = 1;
    repeated string b = 2;
}

You can generate Julia bindings with the protojl function:

using ProtoBuf
protojl("test.proto", ".", "output_dir")

This will create a Julia file at output_dir/test_pb.jl which you can simply include and start using it to encode and decode messages:

include("output_dir/test_pb.jl")
# Main.test_pb

io = IOBuffer();

e = ProtoEncoder(io);

encode(e, test_pb.MyMessage(-1, ["a", "b"]))
# 8

seekstart(io);

d = ProtoDecoder(io);

decode(d, test_pb.MyMessage)
# Main.test_pb.MyMessage(-1, ["a", "b"])
