Updated code for [ProtoBuf.jl 1.0.0](https://discourse.julialang.org/t/ann-protobuf-jl-1-0-0/85885/11)

```julia
# important: .proto files are required in runtime!

const _proj_path = normpath(joinpath(@ __FILE__ , "..", ".."))
const _proto_path = "some_path"

const ENV_ = copy(ENV)
ENV_["JULIA"] = joinpath(Sys.BINDIR, Base.julia_exename())

function protobuf_from_text(
    input::String,
    proto_type::Type{T},
    proto_file = "my.proto"
) where {T}
    proto_type_name = string(Base.typename(proto_type).wrapper)
    args = `--proto_path=$_proto_path --encode=namespace.$proto_type_name $proto_file`
    protoc_jll.protoc() do protoc_path
        inbuf = PipeBuffer()
        write(inbuf, input)
        outbuf = PipeBuffer()
        run(pipeline(setenv(`$protoc_path $args`, ENV_); stdin = inbuf, stdout = outbuf))
        d = ProtoDecoder(outbuf)
        return decode(d, proto_type)::T
    end
end

function protobuf_to_text(input::T, proto_file = "my.proto") where {T}
    proto_type = typeof(input)
    proto_type_name = string(Base.typename(proto_type).wrapper)
    args = `--proto_path=$_proto_path --decode=namespace.$proto_type_name $proto_file`
    protoc_jll.protoc() do protoc_path
        inbuf = PipeBuffer()
        e = ProtoEncoder(inbuf)
        encode(e, input)
        outbuf = PipeBuffer()
        run(pipeline(setenv(`$protoc_path $args`, ENV_); stdin = inbuf, stdout = outbuf))
        return read(outbuf, String)
    end
end
