Unexpected list in typespec: [:high, :low]

[Martin Elvar]

Hi,

First of all, thank you for putting effort into this library. :-)

I'm trying to compile the counter strike proto files found here
https://github.com/SteamRE/SteamKit/blob/master/Resources/Protobufs/csgo/cstrike15_usermessages.proto

If i run protoc -I./ --descriptor_set_out=./protox_test.test cstrike15_usermessages.proto i get no errors, and my file is populated.

But when i run

defmodule Demex.UserMessages do
  @external_resource "./lib/protobufs/cstrike15_usermessages.proto"

  use Protox, files: [
    "./lib/protobufs/cstrike15_usermessages.proto",
  ], namespace: Ost
 end

I can't compile my project, getting the following compile error.

⇒  mix compile

I simply don't know where to look, hope someone can help me.

Could i be, that it's trying to parse this.

Seems to be different params.

== Compilation error in file lib/user_messages.ex ==
** (CompileError) lib/user_messages.ex:4: unexpected list in typespec: [:is_extension, :name_part]

Even tho. i don't change a thing.

Hello, thanks for the report! It's fixed by 0.16.2, available on hex.pm.

Works like a charm, thx for the quick action.
