Unknown wire type: 6

[prewk]

Hi! I'm trying to decode a METADATA.pb from Google Fonts:

name: "Open Sans"
designer: "Steve Matteson"
license: "APACHE2"
category: "SANS_SERIF"
date_added: "2011-02-02"
fonts {
  name: "Open Sans"
  style: "normal"
  weight: 300
  filename: "OpenSans-Light.ttf"
  post_script_name: "OpenSans-Light"
  full_name: "Open Sans Light"
  copyright: "Digitized data copyright © 2010-2011, Google Corporation."
}
fonts {
  name: "Open Sans"
  style: "italic"
  weight: 300
  filename: "OpenSans-LightItalic.ttf"
  post_script_name: "OpenSansLight-Italic"
  full_name: "Open Sans Light Italic"
  copyright: "Digitized data copyright © 2010-2011, Google Corporation."
}
subsets: "menu"
subsets: "cyrillic"
subsets: "cyrillic-ext"
subsets: "devanagari"
subsets: "greek"
subsets: "greek-ext"
subsets: "latin"
subsets: "latin-ext"
subsets: "vietnamese"

With the proto google_font_metadata.proto:

message FamilyProto {
  required string name = 1;
  required string designer = 2;
  required string license = 3;
  required string category = 4;
  required string date_added = 5;
  repeated FontProto fonts = 6;
  repeated string aliases = 7;
  repeated string subsets = 8;
}

message FontProto {
  required string name = 1;
  required string style = 2;
  required int32 weight = 3;
  required string filename = 4;
  required string post_script_name = 5;
  required string full_name = 6;
  optional string copyright = 7;
}

And I'm getting Error: Unknown wire type: 6 when I decode like this:

var messages = protobuf(fs.readFileSync(__dirname + '/google_font_metadata.proto'));
var buf = messages.FamilyProto.decode(fs.readFileSync(__dirname + '/METADATA.pb'));

I assume it has something do with the protocol buffer text format, perhaps? Do I have to do something special in order to enable "text format mode" or something?

Thanks!

text format mode is currently not supported. do you have a link to some docs that describes that format in a formal way and not just the cpp impl?

[prewk]

I found the cpp impl linked in the Developer Guide Overview (scroll down to "while the corresponding protocol buffer message (in protocol buffer text format) is:"), other than that I'm afraid I don't have any info.

Any ideas on how I should approach my problem? My last resort will be manual text parsing without a lib.

How to solve the problem?

Same problem here.
